PART I
Item 1. Business
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 alternatives 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 Composition) and the investment in the External Investment Manager (as 
defined below).
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 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 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.
The following diagram depicts our organizational structure:
___________________________
* 
Other Holding Companies includes the Taxable Subsidiaries, the Structured Subsidiaries and other consolidated 
entities formed for operational purposes. Each of these companies is directly or indirectly wholly-owned by 
MSCC.
** 
The External Investment Manager is accounted for as a portfolio investment at fair value, as opposed to a 
consolidated subsidiary, and is indirectly wholly-owned by MSCC.
CORPORATE INFORMATION
Our principal executive offices are located at 1300 Post Oak Boulevard, 8th Floor, Houston, Texas 77056. We 
maintain a website on the Internet at www.mainstcapital.com. We make available free of charge on our website our annual 
reports on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K, and all amendments to those reports 
as soon as reasonably practicable after such material is electronically filed with or furnished to the SEC. Information 
contained on our website is not incorporated by reference into this Annual Report on Form 10-K, and you should not 
consider that information to be part of this Annual Report on Form 10-K. Our annual reports on Form 10-K, quarterly 
reports on Form 10-Q, current reports on Form 8-K, and all amendments to those reports and other public filings are also 
available free of charge on the EDGAR Database on the SEC’s website at www.sec.gov.
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 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 lien on the assets of the portfolio 
company and typically have a term of between five and seven years from the original investment date.
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. 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 private equity funds 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.
Subject to changes in our cash and overall liquidity, our Investment Portfolio (as defined below) may also include 
short-term portfolio investments that are atypical of our LMM, Private Loan and Middle Market 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. The Investment Portfolio, 
as used herein, refers to all of our investments in LMM portfolio companies, investments in Private Loan portfolio 
companies, investments in Middle Market portfolio companies, Other Portfolio investments, short-term portfolio 
investments and our investment in the External Investment Manager.
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 (see Regulation). 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.
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 shareholders 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). For each of the years ended December 31, 2024 
and 2023, the ratio of our total operating expenses, excluding interest expense, as a percentage of our quarterly average 
total assets was 1.3%. 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%, respectively, for the years ended December 31, 2024 and 2023. Our ratio of 
expenses as a percentage of our average net asset value is described in greater detail in Note F — Financial Highlights to 
the consolidated financial statements included in Item 8. Consolidated Financial Statements and Supplementary Data of 
this Annual Report on Form 10-K.
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 (the “Private Loan Fund”) and MS Private Loan Fund II, LP (the “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 years ended December 31, 2024, 2023 and 2022, the External Investment Manager earned $23.9 million, 
$22.4 million and $21.8 million in base management fees, respectively, $13.7 million, $13.4 million and $2.5 million in 
incentive fees, respectively, and $0.6 million of administrative service fee income for each of the years ended 
December 31, 2024, 2023 and 2022.

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 years ended December 31, 
2024, 2023 and 2022 are net of expenses allocated to the External Investment Manager of $23.1 million, $22.1 million and 
$13.0 million, respectively. 
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 years ended December 31, 2024, 2023, and 2022, dividends accrued by us from the 
External Investment Manager were $11.3 million, $11.3 million and $9.3 million, respectively. For the years ended 
December 31, 2024, 2023 and 2022, the total contribution of the External Investment Manager to our net investment 
income was $34.3 million, $33.4 million and $22.3 million, respectively.
We have received an exemptive order from the SEC permitting co-investments among us, MSC Income and other 
funds and clients advised by 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, the Private Loan Fund, the Private Loan Fund II and other funds and clients 
advised by 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 receive 
performance-based fee compensation from funds and clients advised by the External Investment Manager, this may provide 
the Company and the External Investment Manager an incentive to allocate opportunities to other participating funds and 
clients instead of us. However, both we and the External Investment Manager have policies and procedures in place to 
manage this conflict, including oversight by the independent members of our Board of Directors. In addition to the co-
investment program described above, we also co-invest in syndicated deals and other transactions where price is the only 
negotiated point by us and our affiliates.
BUSINESS STRATEGIES
Our principal investment objective is to maximize our 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 have adopted the 
following business strategies to achieve our investment objective:
•
Deliver Customized Financing Solutions in the Lower Middle Market. We offer LMM portfolio companies 
customized long-term debt and equity financing solutions that are tailored to the facts and circumstances of 
each situation. We believe our ability to provide a broad range of customized financing solutions to LMM 
companies sets us apart from other capital providers that focus on providing a limited number of financing 
alternatives. Our ability to invest across a company’s capital structure, from senior secured loans to 
subordinated debt to equity securities, allows us to offer LMM portfolio companies a comprehensive suite of 
financing options, or a “one-stop” financing solution.
•
Focus on Established Companies. We generally invest in companies with established market positions, 
experienced management teams and proven revenue streams. We believe that those companies generally 
possess better risk-adjusted return profiles than newer companies that are building their management teams or 
are in the early stages of building a revenue base. We also believe that established companies in our targeted 
size range also generally provide opportunities for capital appreciation.

•
Leverage the Skills and Experience of our Investment Team. Our investment team has significant experience 
in lending to and investing in LMM, Private Loan and Middle Market companies. The members of our 
investment team have broad investment backgrounds, with significant experience and long-term tenure with 
Main Street and prior experience at private investment funds, corporate entities with active acquisition growth 
strategies and activities, investment banks and other financial services companies. The expertise of our 
investment team in analyzing, valuing, structuring, negotiating and closing transactions should provide us 
with competitive advantages by allowing us to consider customized financing solutions and non-traditional or 
complex structures for our portfolio companies. Also, the reputation of our investment team has and should 
continue to enable us to generate additional revenue in the form of management and incentive fees in 
connection with us providing advisory services to other investment funds.
•
Invest Across Multiple Companies, Industries, Regions and End Markets. We seek to maintain a portfolio of 
investments that is appropriately balanced among various companies, industries, geographic regions and end 
markets. This portfolio balance is intended to mitigate the potential effects of negative economic events for 
particular companies, regions, industries and end markets.
•
Capitalize on Strong Transaction Sourcing Network. Our investment team seeks to leverage its extensive 
network of referral sources for portfolio company investments. We have developed a reputation in our 
marketplace as a responsive, efficient and reliable source of financing, which has created a growing stream of 
proprietary deal flow for us.
•
Grow our Asset Management Business. Our asset management business provides us with a recurring source 
of income, additional income diversification from sources of income directly tied to invested capital and the 
opportunity for greater stockholder returns through the utilization of our existing investment expertise, strong 
historical track record and favorable reputation. We seek to grow our asset management business within our 
internally managed BDC structure in order to increase the value of this unique benefit to our stakeholders. We 
expect such growth to come organically through the expansion of the investment capital that we manage for 
third parties and the potential extension of our asset management business to new investment strategies, and 
potentially through mergers and acquisition activities.
•
Benefit from Lower, Fixed, Long-Term Cost of Capital. The SBIC licenses held by the Funds have allowed 
them to issue SBA-guaranteed debentures. SBA-guaranteed debentures carry long-term fixed interest rates 
that are generally lower than interest rates on comparable bank loans and other debt. Because lower-cost SBA 
leverage is, and will continue to be, a significant part of our capital base through the Funds, our relative cost 
of debt capital should be lower than many of our competitors. In addition, the SBIC leverage that we receive 
through the Funds represents a stable, long-term component of our capital structure with proper matching of 
duration and cost compared to our LMM portfolio investments. We also maintain investment grade ratings 
from both Standard & Poor’s Ratings Services and Fitch Ratings, which provide us the opportunity and 
flexibility to obtain additional, attractive long-term financing options to supplement our capital structure, 
including the unsecured notes with fixed interest rates we issue. 
INVESTMENT CRITERIA
Our investment team has identified the following investment criteria that it believes are important in evaluating 
prospective portfolio companies. Our investment team uses these criteria in evaluating investment opportunities. However, 
not all of these criteria have been, or will be, met in connection with each of our investments:
•
Proven Management Team with Meaningful Equity Stake. We look for operationally-oriented management 
with direct industry experience and a successful track record. In addition, we expect the management team of 
each LMM portfolio company to have meaningful equity ownership in the portfolio company to better align 
our respective economic interests. We believe management teams with these attributes are more likely to 
manage the companies in a manner that both protects our debt investment and enhances the value of our 
equity investment.
•
Established Companies with Positive Cash Flow. We seek to invest in established companies with sound 
historical financial performance. We primarily pursue investments in LMM companies that have historically 
generated EBITDA of $3 million to $20 million and commensurate levels of free cash flow. We also pursue 
investments in Private Loan companies that have historically generated annual EBITDA of $7.5 million to 
$50 million. We generally do not invest in start-up companies or companies with speculative business plans.

•
Defensible Competitive Advantages/Favorable Industry Position. We primarily focus on companies having 
competitive advantages in their respective markets and/or operating in industries with barriers to entry, which 
may help to protect their market position and profitability.
•
Exit Alternatives. We exit our debt investments primarily through the repayment of our investment from 
internally generated cash flow of the portfolio company and/or a refinancing. In addition, we seek to invest in 
companies whose business models and expected future cash flows may provide alternate methods of repaying 
our investment, such as through a strategic acquisition by other industry participants or a recapitalization.
INVESTMENT PORTFOLIO
Our LMM portfolio investments primarily consist of secured debt, direct equity investments and equity warrants 
in privately held, LMM companies based in the United States. Our Private Loan portfolio investments primarily consist of 
investments in debt securities that are primarily 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 Middle Market portfolio 
investments are generally debt investments in companies owned by private equity funds 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 Other Portfolio investments primarily consist of investments that are not consistent with the typical 
profiles for our LMM, Private Loan and 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.
Debt Investments
Historically, we have made LMM debt investments principally in the form of single tranche debt. Single tranche 
debt financing involves issuing one debt security that blends the risk and return profiles of both first lien secured and 
subordinated debt. We believe that single tranche debt is more appropriate for many LMM companies given their size in 
order to reduce structural complexity and potential conflicts among creditors.
Our LMM debt investments generally have a term of five to seven years from the original investment date, with 
limited required amortization prior to maturity, and provide for monthly or quarterly payment of interest at interest rates 
generally between 10% and 14% per annum, payable currently in cash on either a fixed or floating rate basis. The LMM 
debt investments with floating interest rates will generally bear interest at the Secured Overnight Financing Rate (“SOFR”) 
or the Prime rate typically subject to a contractual minimum interest rate (an “interest rate floor”), plus a margin. In 
addition, certain LMM debt investments may have a form of interest that is not paid currently but is accrued and added to 
the loan balance and paid at maturity. We refer to this form of interest as payment-in-kind, or PIK, interest. We typically 
structure our LMM debt investments with the maximum seniority and collateral that we can reasonably obtain while 
seeking to achieve our total return target. In most cases, our LMM debt investment will be collateralized by a first priority 
lien on substantially all the assets of the portfolio company. In addition to seeking a senior lien position in the capital 
structure of our LMM portfolio companies, we seek to limit the downside potential of our LMM debt investments by 
negotiating covenants that are designed to protect our LMM debt investments while affording our portfolio companies as 
much flexibility in managing their businesses as is reasonable. Such restrictions may include affirmative and negative 
covenants, default penalties, lien protection, change of control or change of management provisions, key-man life 
insurance, guarantees, equity pledges, personal guaranties, where appropriate, and put rights. In addition, we typically seek 
board representation or observation rights in all of our LMM portfolio companies.
While we will continue to focus our LMM debt investments primarily on single tranche debt investments, we may 
structure some of our debt investments as mezzanine loans. These mezzanine loans would be primarily junior secured or 
unsecured, subordinated loans that would provide for relatively high interest rates, payable currently in cash, and would 
provide us with significant interest income. These mezzanine loans would afford us the additional opportunity for income 
and gains through PIK interest and equity warrants and other similar equity instruments issued in conjunction with these 
mezzanine loans. These loans typically would have interest-only payments in the early years, with amortization of principal 
deferred to the later years of the mezzanine loan term. Typically, these mezzanine loans would have maturities of three to 
five years. We would generally target interest rates of 12% to 14%, payable currently in cash, for our mezzanine loan 
investments with higher targeted total returns from equity warrants or PIK interest.

The debt investments in our Private Loan portfolio have rights and protections that are similar to those in our 
LMM debt investments, which may include affirmative and negative covenants, default penalties, lien protection, change 
of control provisions, guarantees and equity pledges. Our Private Loan portfolio debt investments are generally secured by 
a first priority lien and typically have a term of between three and seven years from the original investment date. Our 
Private Loan debt investments generally have floating interest rates at SOFR or Prime rate typically subject to an interest 
rate floor, plus a margin.
Our Middle Market 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. The debt 
investments in our Middle Market portfolio usually have rights and protections that are similar to those in our LMM and 
Private Loan debt investments. The Middle Market debt investments generally have floating interest rates at SOFR or 
Prime rate typically subject to an interest rate floor, plus a margin.
Direct Equity Investments
We also seek to make direct equity investments to align our interests with key management and stockholders of 
our LMM portfolio companies, and to allow for participation in the appreciation in the equity values of our LMM portfolio 
companies. We usually make our direct equity investments in connection with debt investments in our LMM portfolio 
companies. In addition, we may have both equity warrants and direct equity positions in some of our LMM portfolio 
companies. We seek to maintain fully diluted equity positions in our LMM portfolio companies of 5% to 50%, and may 
have controlling equity interests in some instances. We have a value orientation toward our direct equity investments and 
have traditionally been able to purchase our equity investments at reasonable valuations. We will also have, from time to 
time, the opportunity to co-invest with the private equity funds in the equity securities of our Private Loan portfolio 
companies. The equity co-investment aligns our interests with those of the private equity fund and provides us with the 
opportunity to benefit from appreciation in the equity values of our Private Loan portfolio companies.
Warrants
In connection with our LMM debt investments, we occasionally receive equity warrants to establish or increase 
our equity interest in the portfolio company. Warrants that we receive in connection with a debt investment typically 
require only a nominal cost to exercise, and thus, as a portfolio company appreciates in value, we may achieve additional 
investment return from this equity interest. We typically structure the warrants to provide provisions protecting our rights 
as a minority-interest holder, as well as secured or unsecured put rights, or rights to sell such securities back to the portfolio 
company, upon the occurrence of specified events. In certain cases, we also may obtain registration rights in connection 
with these equity interests, which may include demand and “piggyback” registration rights.
INVESTMENT PROCESS
Our management team’s investment committee is responsible for all aspects of our investment processes. The 
current members of our investment committee are Dwayne L. Hyzak, our Chief Executive Officer, David Magdol, our 
President and Chief Investment Officer, and Vincent D. Foster, the Chairman of our Board of Directors.
The investment processes for portfolio investments are outlined below. Our investment strategy involves a “team” 
approach, whereby potential transactions are screened by several members of our investment team before being presented 
to the investment committee. Our investment committee meets on an as-needed basis depending on transaction volume. We 
generally categorize our investment process into seven distinct stages:
Deal Generation/Origination
Deal generation and origination is maximized through long-standing and extensive relationships with industry 
contacts, brokers, commercial and investment bankers, entrepreneurs, service providers such as lawyers, financial advisors 
and accountants, and current and former portfolio companies and investors. Our investment team has developed a 
reputation as a knowledgeable, reliable and active source of capital and assistance in these markets.
Screening
During the screening process, if a transaction initially meets our investment criteria, we will perform preliminary 
due diligence, taking into consideration some or all of the following information:
•
a comprehensive financial model based on quantitative analysis of historical financial performance, 
projections and pro forma adjustments to determine the estimated internal rate of return;
•
a brief industry and market analysis;
Table of contents
9

•
direct industry expertise imported from other portfolio companies or investors;
•
preliminary qualitative analysis of the management team’s competencies and backgrounds;
•
potential investment structures and pricing terms; and
•
regulatory compliance.
Upon successful screening of a proposed transaction, the investment team makes a recommendation to our 
investment committee. If our investment committee concurs with moving forward on the proposed transaction, we typically 
issue a non-binding term sheet or letter of intent to the company.
Term Sheet
For proposed transactions, the non-binding term sheet or letter of intent will include the key economic terms based 
upon our analysis performed during the screening process, as well as a proposed timeline and our qualitative expectation 
for the transaction. While the term sheet or letter of intent for investments is non-binding, we typically receive an expense 
deposit in order to move the transaction to the due diligence phase. Upon execution of a term sheet or letter of intent, we 
begin our formal due diligence process.
Due Diligence
Due diligence on a proposed LMM investment is performed by a minimum of three of our investment 
professionals, whom we refer to collectively as the investment team, and certain external resources, who together conduct 
due diligence to understand the relationships among the prospective portfolio company’s business plan, operations and 
financial performance. Our LMM due diligence review includes some or all of the following:
•
site visits with management and key personnel;
•
detailed review of historical and projected financial statements;
•
operational reviews and analysis;
•
interviews with customers and suppliers;
•
detailed evaluation of company management, including background checks;
•
review of material contracts;
•
in-depth industry, market and strategy analysis;
•
regulatory compliance analysis; and
•
review by legal, environmental or other consultants, if applicable.
Due diligence on a proposed Private Loan investment is generally performed on materials and information 
obtained from certain external resources and assessed internally by a minimum of three of our investment professionals, 
who work to understand the relationships among the prospective portfolio company’s business plan, operations and 
financial performance using the accumulated due diligence information. Our typical Private Loan due diligence review 
includes some or all of the following:
•
detailed review of historical and projected financial statements
•
site visits or other discussions with management and key personnel;
•
in-depth industry, market, operational and strategy analysis;
•
regulatory compliance analysis; and
•
detailed review of the company’s management team and their capabilities.
During the due diligence process, significant attention is given to sensitivity analyses and how the company might 
be expected to perform given downside, base-case and upside scenarios. In certain cases, we may decide not to make an 
investment based on the results of the diligence process.

If any adjustments to the transaction terms or structures are proposed by the investment committee, such changes 
are made and applicable analyses are updated prior to approval of the transaction. Approval for the transaction must be 
made by the affirmative vote from a majority of the members of the investment committee, with the committee member 
managing the transaction, if any, abstaining from the vote. Upon receipt of transaction approval, the investment team will 
re-confirm regulatory compliance, process and finalize all required legal documents, and fund the investment.

Post-Investment
We continuously monitor the status and progress of the portfolio companies. We generally offer managerial 
assistance to our portfolio companies, giving them access to our investment experience, direct industry expertise and 
contacts. The same investment team that was involved in the investment process will continue its involvement in the 
portfolio company post-investment. This provides for continuity of knowledge and allows the investment team to maintain 
a strong business relationship with key management of our portfolio companies for post-investment assistance and 
monitoring purposes.
As part of the monitoring process of LMM portfolio investments, the investment team will analyze monthly and 
quarterly financial statements versus the previous periods and year, review financial projections, meet and discuss issues or 
opportunities with management, attend board meetings and review all compliance certificates and covenants. While we 
maintain limited involvement in the ordinary course operations of our LMM portfolio companies, we maintain a higher 
level of involvement in non-ordinary course financing or strategic activities and any non-performing scenarios. 
As part of the monitoring process of our Private Loan and Middle Market portfolio investments, the investment 
team will analyze monthly and quarterly financial statements versus the previous periods and year, review financial 
projections and review all compliance certificates and covenants. Depending upon the nature of our Private Loan and 
Middle Market portfolio investments, our investment team may also attend board meetings, and meet and discuss issues or 
opportunities with the portfolio company’s management team or private equity owners, however, due to the nature of our 
“lender only” relationship with these Private Loan and Middle Market companies in comparison to our LMM portfolio 
companies, is is not practical to have as much direct management interface.
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.
Exit Strategies/Refinancing
While we generally exit most investments through the refinancing or repayment of our debt and redemption or 
sale of our equity positions, we typically assist our LMM portfolio companies in developing and planning exit 
opportunities, including any sale or merger of our portfolio companies. We may also assist in the structure, timing, 
execution and transition of the exit strategy. The refinancing or repayment of Private Loan investments and Middle Market 
debt investments typically do not require our assistance due to the additional resources available to these larger Private 
Loan and Middle Market companies.
DETERMINATION OF NET ASSET VALUE AND INVESTMENT PORTFOLIO VALUATION PROCESS
We determine the net asset value (“NAV”) per share of our common stock on a quarterly basis. The NAV per 
share is equal to our total assets minus total liabilities divided by the total number of shares of common stock outstanding.
We are required to report our investments at fair value. As a result, 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 follow the provisions of the Financial Accounting Standards Board 
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.
We determine in good faith the fair value of our Investment Portfolio pursuant to a valuation policy in accordance 
with ASC 820 and a valuation process approved by our Board of Directors and in accordance with the 1940 Act. Our 
valuation policies and processes are intended to provide a consistent basis for determining the fair value of our Investment 
Portfolio. See Note B.1. — Summary of Significant Accounting Policies — Valuation of the Investment Portfolio included 
in Item 8. Consolidated Financial Statements and Supplementary Data of this Annual Report on Form 10-K for a detailed 
discussion of our Investment Portfolio valuation process and procedures.
Table of contents
12

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.
The 1940 Act requires valuation of a portfolio security at “market value” if market quotations for the security are 
“readily available.” Portfolio securities for which market quotations are not readily available must be valued at fair value as 
determined in good faith by the board of directors. 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 designated a group of our executive officers to serve as the Board’s valuation designee thereunder (the “Valuation 
Committee”). Pursuant to the Valuation Procedures, we undertake a multi-step process each quarter in connection with 
determining the fair value of our investments. 
The following outlines our valuation process as established under the Valuation Procedures:
•
Our quarterly process begins with an initial valuation of each portfolio investment performed by the valuation 
team consisting of several professionals who apply the appropriate valuation methodology depending on the 
type of investment.
•
Each valuation model is then reviewed by the investment team responsible for monitoring the portfolio 
investment for accuracy, with any recommended changes reviewed by the valuation team.
•
Updated valuation conclusions are then reviewed by and discussed with the Valuation Committee at quarterly 
valuation meetings. Valuation meetings are generally attended by the Valuation Committee, the valuation 
team, members of the investment team responsible for each investment and members of the compliance team. 
Valuation models and valuation conclusions are adjusted as necessary following such meetings.
•
A nationally recognized independent financial advisory services firm analyzes and provides observations, 
recommendations and an assurance certification regarding the determinations of the fair value for the majority 
of our portfolio companies on a rotational basis.
•
After incorporating commentary by the Valuation Committee and review of recommendations provided by 
the independent financial advisory services firm, valuation results are finalized and approved by the Valuation 
Committee.
•
The Board of Directors oversees the process through its Audit Committee in accordance with Rule 2a-5 
pursuant to the Valuation Procedures.
Determination of fair value involves subjective judgments and estimates. The notes to our consolidated financial 
statements refer to the uncertainty with respect to the possible effect of such valuations, and any change in such valuations, 
on our financial results and financial condition.
COMPETITION
We compete for investments with a number of investment funds (including private equity funds, mezzanine funds, 
BDCs and SBICs), as well as traditional financial services companies such as commercial banks and other sources of 
financing. Many of the entities that compete with us are larger and have more resources available to them. We believe we 
are able to be competitive with these entities primarily on the basis of our focus on the underserved companies described in 
our LMM investment strategy and the less competitive nature of the market for companies described in our Private Loan 
investment strategy, the experience and contacts of our management team, our responsive and efficient investment analysis 
and decision-making processes, our comprehensive suite of customized financing solutions and the investment terms we 
offer.

We believe that some of our competitors make senior secured loans, junior secured loans and subordinated debt 
investments with interest rates and returns that are comparable to or lower than the rates and returns that we target. 
Therefore, we do not seek to compete primarily on the interest rates and returns that we offer to potential portfolio 
companies. For additional information concerning the competitive risks we face, see Item 1A. Risk Factors — Risks Related 
to Our Business and Structure — We face increasing competition for investment opportunities.
HUMAN CAPITAL
Our employees are vital to our success as a principal investment firm. As a human-capital intensive business, the 
long-term success of our company depends on our people. We strive to attract, develop and retain our employees by 
offering unique employment opportunities, superior advancement and promotion opportunities, attractive compensation 
and benefit structures and a close-knit culture. The departure of our key investment and other personnel could cause our 
operating results to suffer. 
Our LMM business depends heavily on the business owners and management teams of our portfolio companies 
and their respective employees, contractors and service providers. In our investment process for LMM portfolio 
investments, the analysis of these individuals is a critical part of our overall investment underwriting process and as a result 
we carefully review the qualifications and experience of the portfolio company’s business owners and management team 
and their employment practices. We strive to partner with business owners and management teams whose business 
practices reflect our core values. 
We strive to recruit talented and driven individuals who share our values. We have competitive programs 
dedicated to attracting and retaining new talent and enhancing the skills of our employees. Our recruiting efforts utilize 
strong relationships with a variety of sources from which we recruit. Among other opportunities, we offer selected students 
investment analyst internships, which are expected to lead to permanent roles for high performing and high potential 
interns. Through our internship program, individuals who want to become investment analysts have the opportunity to see 
the full investment process from origination to closing, as well as post-closing portfolio management activities. We 
routinely recruit from within, promoting current employees who have shown the technical ability, attitude, interest and the 
initiative to take on greater responsibility. 
We have designed a compensation structure, including an array of benefit plans and programs, that we believe is 
attractive to our current and prospective employees. We also offer formal and informal training and mentorship programs 
that provide employees with access to senior level executives. Through our annual goal setting and performance review 
processes, our employees are annually evaluated by supervisors and our senior management team to ensure employees 
continue to develop and advance as expected. We are committed to having a diverse workforce, and an inclusive work 
environment is a natural extension of our culture. We also maintain a Women’s Initiative that provides employees with 
opportunities to network internally at Main Street and externally with other women in the financial services industry. Our 
employees have access to several programs designed to enable our employees to balance work, family and family-related 
situations including flexible working arrangements and parental leave for birth and adoption placement. We are committed 
to creating and maintaining an atmosphere where all employees feel welcomed, valued, respected and heard so that they 
feel motivated and encouraged to contribute fully to their careers, our company and our communities.
We seek to maintain a close-knit culture, which we believe is an important factor in employee retention, which is 
reinforced by our Community Building Committee. Our Community Building Committee, which is composed of a 
substantial cross section of employees across our organization, develops programs and initiatives that promote an open and 
inclusive atmosphere and encourage employee outreach with our community, in each case based upon feedback received 
from our employees. Initiatives generated by our Community Building Committee include employee well-being and 
engagement activities along with volunteer and donation opportunities with local charitable organizations. We encourage 
you to visit our website for more information about charitable organizations receiving our ongoing support. Nothing on our 
website, however, shall be deemed incorporated by reference into this Annual Report on Form 10-K.
We monitor and evaluate various turnover and attrition metrics throughout our management team. Our annualized 
voluntary turnover is relatively low, a record which we attribute to our strong corporate culture, commitment to career 
development and attractive compensation and benefit programs. For additional information concerning the competitive 
risks we face, see Item 1A. Risk Factors — Risks Related to Our Business and Structure — Our success depends on 
attracting and retaining qualified personnel in a competitive environment.

As of December 31, 2024, we had 104 employees, 58 of whom we characterize as investment and portfolio 
management professionals, and the others include operations professionals and administrative staff. None of our employees 
are represented by a collective bargaining agreement. As necessary, we will hire additional investment professionals and 
administrative personnel. All but three of our employees are located in our Houston, Texas office.
REGULATION
Regulation as a Business Development Company
We have elected to be regulated as a BDC under the 1940 Act. The 1940 Act contains prohibitions and restrictions 
relating to transactions between BDCs and their affiliates, principal underwriters and affiliates of those affiliates or 
underwriters. The 1940 Act requires that a majority of the members of the board of directors of a BDC be persons other 
than “interested persons,” as that term is defined in the 1940 Act. In addition, the 1940 Act provides that we may not 
change the nature of our business so as to cease to be, or to withdraw our election as, a BDC unless approved by a majority 
of our outstanding voting securities.
The 1940 Act defines “a majority of the outstanding voting securities” as the lesser of (i) 67% or more of the 
voting securities present at a meeting if the holders of more than 50% of our outstanding voting securities are present or 
represented by proxy or (ii) more than 50% of our outstanding voting securities.
Qualifying Assets
Under the 1940 Act, a BDC may not acquire any asset other than assets of the type listed in Section 55(a) of the 
1940 Act, which are referred to as qualifying assets, unless, at the time the acquisition is made, qualifying assets represent 
at least 70% of the company’s total assets. The principal categories of qualifying assets relevant to our business are any of 
the following:
(1)
Securities purchased in transactions not involving any public offering from the issuer of such securities, 
which issuer (subject to certain limited exceptions) is an eligible portfolio company (as defined below), 
or from any person who is, or has been during the preceding 13 months, an affiliated person of an eligible 
portfolio company, or from any other person, subject to such rules as may be prescribed by the SEC.
(2)
Securities of any eligible portfolio company that we control.
(3)
Securities purchased in a private transaction from a U.S. issuer that is not an investment company or 
from an affiliated person of the issuer, or in transactions incident thereto, if the issuer is in bankruptcy 
and subject to reorganization or if the issuer, immediately prior to the purchase of its securities was 
unable to meet its obligations as they came due without material assistance other than conventional 
lending or financing arrangements.
(4)
Securities of an eligible portfolio company purchased from any person in a private transaction if there is 
no ready market for such securities and we already own 60% of the outstanding equity of the eligible 
portfolio company.
(5)
Securities received in exchange for or distributed on or with respect to securities described in (1) through 
(4) above, or pursuant to the exercise of warrants or rights relating to such securities.
(6)
Cash, cash equivalents, U.S. government securities or high-quality debt securities maturing in one year or 
less from the time of investment.
In addition, a BDC must have been organized and have its principal place of business in the United States and 
must be operated for the purpose of making investments in the types of securities described in (1), (2) or (3) above.
An eligible portfolio company is defined in the 1940 Act as any issuer which:
(a)
is organized under the laws of, and has its principal place of business in, the United States;
(b)
is not an investment company (other than a small business investment company wholly-owned by the 
BDC) or a company that would be an investment company but for certain exclusions under the 1940 Act; 
and
Table of contents
15

(c)
satisfies any of the following:
(i)
does not have any class of securities that is traded on a national securities exchange or has a 
class of securities listed on a national securities exchange but has an aggregate market value of 
outstanding voting and non-voting common equity of less than $250 million;
(ii)
is controlled by a BDC or a group of companies including a BDC and the BDC has an affiliated 
person who is a director of the eligible portfolio company; or
(iii)
is a small and solvent company having total assets of not more than $4 million and capital and 
surplus of not less than $2 million.
Managerial Assistance to Portfolio Companies
As noted above, a BDC must be operated for the purpose of making investments in the type of securities described 
in (1), (2) or (3) above under the heading entitled “— Qualifying Assets.” In addition, BDCs must generally offer to make 
available to such issuer of the securities (other than small and solvent companies described above) significant managerial 
assistance. Making available managerial assistance means, among other things, any arrangement whereby the BDC, 
through its directors, officers or employees, offers to provide, and, if accepted, does so provide, significant guidance and 
counsel concerning the management, operations or business objectives and policies of a portfolio company. However, if a 
BDC purchases securities in conjunction with one or more other persons acting together, one of the other persons in the 
group may make available such significant managerial assistance on behalf of all investors in the group.
Temporary Investments
Pending investment in “qualifying assets,” as described above, our investments may consist of cash, cash 
equivalents, U.S. government securities and high-quality debt securities maturing in one year or less from time of 
investment therein, so that 70% of our assets are qualifying assets.
Senior Securities
Prior to 2018 legislation that modified the asset coverage requirements of the 1940 Act, we were permitted, as a 
BDC, to issue senior securities only in amounts such that our asset coverage, or BDC asset coverage ratio, as defined in the 
1940 Act, equals at least 200% of all debt and/or senior stock immediately after each such issuance. However, 2018 
legislation modified the 1940 Act by allowing a BDC to increase the maximum amount of leverage it may incur such that a 
BDC’s asset coverage ratio could be reduced from an asset coverage ratio of 200% to an asset coverage ratio of 150%, if 
certain requirements are met. In May 2022, our stockholders approved the application of the reduced BDC asset coverage 
ratio. As a result, the BDC asset coverage ratio applicable to us decreased from 200% to 150% effective May 3, 2022.
We have received exemptive relief from the SEC to permit us to exclude the SBA-guaranteed debentures of the 
Funds from our 150% asset coverage test under the 1940 Act. As such, our ratio of total consolidated assets to outstanding 
indebtedness may be less than 150%. This provides us with increased investment flexibility but also increases our risks 
related to leverage.
In addition, while any senior securities remain outstanding (other than senior securities representing indebtedness 
issued in consideration of a privately arranged loan which is not intended to be publicly distributed), we must generally 
include provisions in the documents governing new senior securities to prohibit any cash distribution to our stockholders or 
the repurchase of such securities or shares unless we meet the applicable asset coverage ratios at the time of the distribution 
or repurchase. We may also borrow amounts up to 5% of the value of our total assets for temporary or emergency purposes 
without regard to asset coverage with such borrowings not constituting senior securities for purposes of the asset coverage 
ratio requirements of the 1940 Act. A loan is presumed to be for temporary purposes if it is repaid within sixty days and not 
extended or renewed. For a discussion of the risks associated with leverage, see Item 1A. Risk Factors — Risks Related to 
Leverage, including, without limitation, — Because we borrow money, the potential for gain or loss on amounts invested in 
us is magnified and may increase the risk of investing in us.

Common Stock
We are not generally able to issue and sell our common stock at a price below NAV per share. We may, however, 
sell our common stock, warrants, options or rights to acquire our common stock, at a price below the current NAV of the 
common stock if our Board of Directors determines that such sale is in our best interests and that of our stockholders, and 
our stockholders approve such sale. In any such case, the price at which our securities are to be issued and sold may not be 
less than a price which, in the determination of our Board of Directors, closely approximates the market value of such 
securities (less any distributing commission or discount). 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 2024 Annual Meeting of Stockholders, 
and have not sought such stockholder authorization since 2012, because our common stock price had been trading 
significantly above the NAV per share of our common stock since 2011. Our stockholders have previously approved a 
proposal that authorizes us to issue securities to subscribe to, convert to, or purchase shares of our common stock in one or 
more offerings. We may also make rights offerings to our stockholders at prices per share less than the NAV per share, 
subject to applicable requirements of the 1940 Act. See Item 1A. Risk Factors — Risks Related to our Securities — 
Stockholders may incur dilution if we sell shares of our common stock in one or more offerings at prices below the then 
current NAV per share of our common stock or issue securities to subscribe to, convert to or purchase shares of our 
common stock.
Code of Ethics
We have adopted a code of ethics pursuant to Rule 17j-1 under the 1940 Act that establishes procedures for 
personal investments and restricts certain personal securities transactions. Personnel subject to the code may invest in 
securities for their personal investment accounts, including securities that may be purchased or held by us, so long as such 
investments are made in accordance with the code’s requirements. The code of ethics is available on the EDGAR Database 
on the SEC’s website at http://www.sec.gov.
Proxy Voting Policies and Procedures
We vote proxies relating to our portfolio securities in a manner in which we believe is consistent with the best 
interest of our stockholders. We review on a case-by-case basis each proposal submitted to a stockholder vote to determine 
its impact on the portfolio securities held by us. Although we generally vote against proposals that we expect would have a 
negative impact on our portfolio securities, we may vote for such a proposal if there exists compelling long-term reasons to 
do so.
Our proxy voting decisions are made by the investment team which is responsible for monitoring each of our 
investments. To ensure that our vote is not the product of a conflict of interest, we require that anyone involved in the 
decision-making process discloses to our chief compliance officer any potential conflict regarding a proxy vote of which he 
or she is aware.
Stockholders may obtain information, without charge, regarding how we voted proxies with respect to our 
portfolio securities by making a written request for proxy voting information to: Chief Compliance Officer, 1300 Post Oak 
Boulevard, 8th Floor, Houston, Texas 77056.
Other 1940 Act Regulations
We are also prohibited under the 1940 Act from knowingly participating in certain transactions with our affiliates 
without the prior approval of our Board of Directors who are not interested persons and, in some cases, prior approval by 
the SEC.
We are required to provide and maintain a bond issued by a reputable fidelity insurance company to protect us 
against larceny and embezzlement. Furthermore, as a BDC, we are prohibited from protecting any director or officer 
against any liability to us or our stockholders arising from willful misfeasance, bad faith, gross negligence or reckless 
disregard of the duties involved in the conduct of such person’s office.
We are required to adopt and implement written policies and procedures reasonably designed to prevent violation 
of the federal securities laws, review these policies and procedures no less frequently than annually for their adequacy and 
the effectiveness of their implementation, and to designate a chief compliance officer to be responsible for administering 
the policies and procedures.
We may be periodically examined by the SEC for compliance with the 1940 Act.

Small Business Investment Company Regulations
Each of the Funds is licensed by the SBA to operate as a SBIC under Section 301(c) of the Small Business 
Investment Act of 1958. MSMF obtained its SBIC license in 2002 and MSC III obtained its license in 2016.
SBICs are designed to stimulate the flow of private capital to eligible small businesses. Under SBIC regulations, 
SBICs may make loans to eligible small businesses, invest in the equity securities of such businesses and provide them 
with consulting and advisory services. Each of the Funds has typically invested in secured debt, acquired warrants and/or 
made equity investments in qualifying small businesses.
The Funds are subject to regulation and oversight by the SBA, including requirements with respect to reporting 
financial information, such as the extent of capital impairment if applicable, on a regular basis and annual examinations 
conducted by the SBA. The SBA, as a creditor, will have a superior claim to the Funds’ assets over our securities holders in 
the event the Funds are liquidated or the SBA exercises its remedies under the SBA-guaranteed debentures issued by the 
Funds upon an event of default.
Under present SBIC regulations, eligible small businesses generally include businesses that (together with their 
affiliates) have a tangible net worth not exceeding $24 million or have average annual net income after U.S. federal income 
taxes not exceeding $8 million (average net income to be computed without benefit of any carryover loss) for the two most 
recent fiscal years. In addition, an SBIC must devote 25% of its investment activity to “smaller enterprises” as defined by 
the SBA. A smaller enterprise generally includes businesses that have a tangible net worth not exceeding $6 million and 
have average annual net income after U.S. federal income taxes not exceeding $2 million (average net income to be 
computed without benefit of any net carryover loss) for the two most recent fiscal years. SBIC regulations also provide 
alternative size standard criteria to determine eligibility for designation as an eligible small business or smaller enterprise, 
which criteria depend on the primary industry in which the business is engaged and are based on such factors as the number 
of employees and gross revenue. However, once an SBIC has invested in a company, it generally may continue to make 
follow-on investments in the company, regardless of the size of the portfolio company at the time of the follow-on 
investment, up to the time of the portfolio company’s initial public offering.
The SBA prohibits an SBIC from providing funds to small businesses for certain purposes, such as relending and 
investment outside the United States, to businesses engaged in certain prohibited industries, and to certain “passive” (non-
operating) companies. In addition, without prior SBA approval, an SBIC may not invest an amount equal to more than 30% 
of the SBIC’s regulatory capital, as defined by the SBA, in any one portfolio company and its affiliates.
The SBA places certain limitations on the financing terms of investments by SBICs in portfolio companies (such 
as limiting the permissible interest rate on debt securities held by an SBIC in a portfolio company). Included in such 
limitations are SBIC regulations which allow an SBIC to exercise control over a small business for a period of seven years 
from the date on which the SBIC initially acquires its control position. This control period may be extended for an 
additional period of time with the SBA’s prior written approval.
The SBA restricts the ability of an SBIC to lend money to any of its officers, directors and employees or to invest 
in affiliates thereof. The SBA also prohibits, without prior SBA approval, a “change of control” of an SBIC or transfers 
that would result in any person (or a group of persons acting in concert) owning 10% or more of a class of equity of a 
licensed SBIC. A “change of control” is any event which would result in the transfer of the power, direct or indirect, to 
direct the management and policies of an SBIC, whether through ownership, contractual arrangements or otherwise.
The SBIC licenses allow the Funds to incur leverage by issuing SBA-guaranteed debentures, subject to the 
issuance of a capital commitment and certain approvals by the SBA and customary procedures. SBA-guaranteed 
debentures carry long-term fixed rates that are generally lower than rates on comparable bank and other debt. Under 
applicable regulations, an SBIC may generally have outstanding debentures guaranteed by the SBA in amounts up to twice 
the amount of the privately raised funds of the SBIC. Debentures guaranteed by the SBA have a maturity of ten years, 
require semiannual payments of interest, do not require any principal payments prior to maturity, and are not subject to 
prepayment penalties. As of December 31, 2024, we, through the Funds, had $350.0 million of outstanding SBA-
guaranteed debentures, which had an annual weighted-average interest rate of 3.3%.

SBICs must invest idle funds that are not being used to make loans in investments permitted under SBIC 
regulations in the following limited types of securities: (i) direct obligations of, or obligations guaranteed as to principal 
and interest by, the United States government, which mature within 15 months from the date of the investment; (ii) 
repurchase agreements with federally insured institutions with a maturity of seven days or less (and the securities 
underlying the repurchase obligations must be direct obligations of or guaranteed by the federal government); (iii) mutual 
funds, securities or other instruments that exclusively consist of, or represented pooled assets of investments described in 
(i) and (ii) above; (iv) certificates of deposit with a maturity of one year or less, issued by a federally insured institution; (v) 
a deposit account in a federally insured institution that is subject to a withdrawal restriction of one year or less; (vi) a 
checking account in a federally insured institution; or (vii) a reasonable petty cash fund.
SBICs are periodically examined and audited by the SBA’s staff to determine their compliance with SBIC 
regulations and are periodically required to file certain financial information and other documents with the SBA.
Neither the SBA nor the U.S. government or any of its agencies or officers has approved any ownership interest to 
be issued by us or any obligation that we or any of our subsidiaries may incur.
Securities Exchange Act of 1934 and Sarbanes-Oxley Act Compliance
We are subject to the reporting and disclosure requirements of the Securities Exchange Act of 1934 (the 
“Exchange Act”), including the filing of quarterly, annual and current reports, proxy statements and other required items. 
In addition, we are subject to the Sarbanes-Oxley Act of 2002, which imposes a wide variety of regulatory requirements on 
publicly-held companies and their insiders. For example:
•
pursuant to Rule 13a-14 of the Exchange Act, our Chief Executive Officer and Chief Financial Officer are 
required to certify the accuracy of the consolidated financial statements contained in our periodic reports;
•
pursuant to Item 307 of Regulation S-K, our periodic reports are required to disclose our conclusions about 
the effectiveness of our disclosure controls and procedures;
•
pursuant to Rule 13a-15 of the Exchange Act, our management is required to prepare a report regarding its 
assessment of our internal control over financial reporting, and our independent registered public accounting 
firm separately audits our internal control over financial reporting; and
•
pursuant to Item 308 of Regulation S-K and Rule 13a-15 of the Exchange Act, our periodic reports must 
disclose whether there were significant changes in our internal control over financial reporting or in other 
factors that could significantly affect these controls subsequent to the date of their evaluation, including any 
corrective actions with regard to significant deficiencies and material weaknesses.
The New York Stock Exchange Corporate Governance Regulations
The New York Stock Exchange (“NYSE”) has adopted corporate governance regulations that listed companies 
must comply with. We believe we are in compliance with such corporate governance listing standards. We intend to 
monitor our compliance with all future listing standards and to take all necessary actions to ensure that we stay in 
compliance.
Investment Adviser Regulations
The External Investment Manager, which is wholly-owned by us, is subject to regulation under the Investment 
Advisers Act of 1940, as amended (the “Advisers Act”). The Advisers Act establishes, among other things, recordkeeping 
and reporting requirements, disclosure requirements, limitations on transactions between the adviser’s account and an 
advisory client’s account, limitations on transactions between the accounts of advisory clients, and general anti-fraud 
prohibitions. The External Investment Manager may be examined by the SEC from time to time for compliance with the 
Advisers Act.

Taxation as a Regulated Investment Company
MSCC has elected to be treated for U.S. federal income tax purposes as a RIC under Subchapter M of the Code. 
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 income that we distribute to our stockholders as dividends. To qualify as a RIC, we must, 
among other things, meet certain source-of-income and asset diversification requirements (as described below). In addition, 
in order to obtain RIC tax treatment, we must distribute to our stockholders, for each taxable year, at least 90% of our 
“investment company taxable income,” which is generally our net ordinary taxable income plus the excess of realized net 
short-term capital gains over realized net long-term capital losses, and 90% of our tax-exempt income (the “Annual 
Distribution Requirement”). 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.
For any taxable year in which we qualify as a RIC and satisfy the Annual Distribution Requirement, we will not 
be subject to U.S. federal income tax on the portion of our income or capital gains we distribute (or are deemed to 
distribute) to stockholders. We will be subject to U.S. federal income tax at the regular corporate rates on any income or 
capital gains not distributed (or deemed distributed) to our stockholders.
We are subject to a 4% non-deductible U.S. federal excise tax on certain undistributed income unless we distribute 
in a timely manner an amount at least equal to the sum of (1) 98% of our net ordinary taxable income for each calendar 
year, (2) 98.2% of our capital gain net income for the one-year period ending December 31 in that calendar year and (3) 
any taxable income recognized, but not distributed, in preceding years on which we paid no U.S. federal income tax (the 
“Excise Tax Avoidance Requirement”). Dividends declared and paid by us in a year will generally differ from taxable 
income for that year as such dividends may include the distribution of current year taxable income, exclude amounts 
carried over into the following year, and include the distribution of prior year taxable income carried over into and 
distributed in the current year. For amounts we carry over into the following year, we will be required to pay the 4% U.S. 
federal excise tax on the excess of 98% of our annual investment company taxable income and 98.2% of our capital gain 
net income over our distributions for the year.
In order to qualify as a RIC for U.S. federal income tax purposes, we must, among other things:
•
continue to qualify as a BDC under the 1940 Act at all times during each taxable year;
•
derive in each taxable year at least 90% of our gross income from dividends, interest, payments with respect 
to certain securities, loans, gains from the sale of stock or other securities, net income from certain “qualified 
publicly traded partnerships,” or other income derived with respect to our business of investing in such stock 
or securities (the “90% Income Test”); and
•
diversify our holdings so that at the end of each quarter of the taxable year:
•
at least 50% of the value of our assets consists of cash, cash equivalents, U.S. government securities, 
securities of other RICs, and other securities if such other securities of any one issuer do not represent 
more than 5% of the value of our assets or more than 10% of the outstanding voting securities of the 
issuer; and
•
no more than 25% of the value of our assets is invested in the securities, other than U.S. government 
securities or securities of other RICs, (i) of one issuer, (ii) of two or more issuers that are controlled, as 
determined under applicable Code rules, by us and that are engaged in the same or similar or related 
trades or businesses or (iii) of certain “qualified publicly traded partnerships” (collectively, the 
“Diversification Tests”).

In order to comply with the 90% Income Test, we formed the Taxable Subsidiaries as wholly-owned taxable 
subsidiaries for the primary purpose of permitting us to own equity interests in portfolio companies which are “pass-
through” entities for tax purposes. Absent the taxable status of the Taxable Subsidiaries, a portion of the gross income from 
such portfolio companies would flow directly to us for purposes of the 90% Income Test. To the extent such income did 
not consist of income derived from securities, such as dividends and interest, it could jeopardize our ability to qualify as a 
RIC and, therefore, cause us to incur significant U.S. federal income taxes. The Taxable Subsidiaries are consolidated with 
Main Street for generally accepted accounting principles in the United States of America (“U.S. GAAP”) purposes and are 
included in our consolidated financial statements, and the portfolio investments held by the Taxable Subsidiaries are 
included in our consolidated financial statements. The Taxable Subsidiaries are not consolidated with MSCC for income 
tax purposes and may generate income tax expense, or benefit, as a result of their ownership of the portfolio investments. 
The income tax expense, or benefit, if any, and any related tax assets and liabilities, are reflected in our consolidated 
financial statements.
The External Investment Manager is accounted for as a portfolio investment for U.S. GAAP purposes and is an 
indirect wholly-owned subsidiary of MSCC, owned through a Taxable Subsidiary. The External Investment Manager is 
owned by a Taxable Subsidiary in order to allow us to comply with the 90% Income Test, since the External Investment 
Manager’s income would likely not consist of income derived from securities, such as dividends and interest, and as result, 
if held directly by us, it could jeopardize our ability to qualify as a RIC and, therefore, cause us to incur significant U.S. 
federal income taxes. As it is wholly-owned by a Taxable Subsidiary, the External Investment Manager is disregarded for 
tax purposes. The External Investment Manager has also 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.
We may be required to recognize taxable income in circumstances in which we do not receive cash. For example, 
if we hold debt obligations that are treated under applicable tax rules as having original issue discount (such as debt 
instruments issued with warrants and debt securities invested in at a discount to par), we must include in income each year 
a portion of the original issue discount that accrues over the life of the obligation, regardless of whether cash representing 
such income is received by us in the same taxable year. We may also have to include in income other amounts that we have 
not yet received in cash such as PIK interest, cumulative dividends or amounts that are received in non-cash compensation 
such as warrants or stock. Because any original issue discount or other amounts accrued will be included in our investment 
company taxable income for the year of accrual, we may be required to make a distribution to our stockholders in order to 
satisfy the Annual Distribution Requirement, even though we will not have received any corresponding cash amount.
Although we do not presently expect to do so, we are authorized to borrow funds and to sell assets in order to 
satisfy distribution requirements. However, under the 1940 Act, we are not permitted to make distributions to our 
stockholders in certain circumstances while our debt obligations and other senior securities are outstanding unless certain 
“asset coverage” tests are met. See Regulation — Regulation as a Business Development Company — Senior Securities. 
Moreover, our ability to dispose of assets to meet our distribution requirements may be limited by (1) the illiquid nature of 
our portfolio and/or (2) other requirements relating to our status as a RIC, including the Diversification Tests. If we dispose 
of assets in order to meet the Annual Distribution Requirement or the Excise Tax Avoidance Requirement, we may make 
such dispositions at times that, from an investment standpoint, are not advantageous.

We may distribute taxable dividends that are payable in part in our stock. Under certain applicable provisions of 
the Code and the U.S. Department of the Treasury (“Treasury”) regulations, distributions payable by us in cash or in shares 
of stock (at the stockholders’ election) would satisfy the Annual Distribution Requirement. The Internal Revenue Service 
has issued guidance indicating that this rule will apply even where the total amount of cash that may be distributed is 
limited to no more than 20% of the total distribution. According to this guidance, if too many stockholders elect to receive 
their distributions in cash, each such stockholder would receive a pro rata share of the total cash to be distributed and would 
receive the remainder of their distribution in shares of stock. Taxable stockholders receiving such dividends will be 
required to include the full amount of the dividend (whether received in cash, our stock, or a combination thereof) as (i) 
ordinary income (including any qualified dividend income that, in the case of a noncorporate stockholder, may be eligible 
for the same reduced maximum tax rate applicable to long-term capital gains to the extent such distribution is properly 
reported by us as qualified dividend income and such stockholder satisfies certain minimum holding period requirements 
with respect to our stock) or (ii) long-term capital gain (to the extent such distribution is properly reported as a capital gain 
dividend), to the extent of our current and accumulated earnings and profits for U.S. federal income tax purposes. As a 
result, a U.S. stockholder may be required to pay tax with respect to such dividends in excess of any cash received. If a 
U.S. stockholder sells the stock it receives in order to pay this tax, the sales proceeds may be less than the amount included 
in income with respect to the dividend, depending on the market price of our stock at the time of the sale. Furthermore, 
with respect to non-U.S. stockholders, we may be required to withhold U.S. tax with respect to such dividends, including in 
respect of all or a portion of such dividend that is payable in stock. In addition, if a significant number of our stockholders 
determine to sell shares of our stock in order to pay taxes owed on dividends, it may put downward pressure on the trading 
price of our stock.
Failure to Qualify as a RIC
If we fail to satisfy the 90% Income Test or the Diversification Tests for any taxable year, we may nevertheless 
continue to qualify as a RIC for such year if certain relief provisions are applicable (which may, among other things, 
require us to pay certain corporate-level U.S. federal taxes or to dispose of certain assets). We cannot assure you that we 
will qualify for any such relief should we fail the 90% Income Test or the Diversification Tests.
If we were unable to qualify for treatment as a RIC and the foregoing relief provisions are not applicable, we 
would be subject to tax on all of our taxable income at regular corporate rates. We would not be able to deduct distributions 
to stockholders, nor would they be required to be made. If we were subject to tax on all of our taxable income at regular 
corporate rates, then distributions we make after being subject to such tax would be taxable to our stockholders and, 
provided certain holding period and other requirements were met, could qualify for treatment as “qualified dividend 
income” eligible for the maximum 20% rate (plus a 3.8% Medicare surtax, if applicable) applicable to qualified dividends 
to the extent of our current and accumulated earnings and profits. Subject to certain limitations under the Code, corporate 
taxpayers would be eligible for a dividends-received deduction on distributions they receive. Distributions in excess of our 
current and accumulated earnings and profits would be treated first as a return of capital to the extent of the stockholder’s 
tax basis, and any remaining distributions would be treated as a capital gain. To requalify as a RIC in a subsequent taxable 
year, we would be required to satisfy the RIC qualification requirements for that year and dispose of any earnings and 
profits from any year in which we failed to qualify as a RIC. Subject to a limited exception applicable to RICs that 
qualified as such under Subchapter M of the Code for at least one year prior to disqualification and that requalify as a RIC 
no later than the second year following the nonqualifying year, we could be subject to tax on any unrealized net built-in 
gains in the assets held by us during the period in which we failed to qualify as a RIC that are recognized within the 
subsequent five years, unless we made a special election to pay corporate-level U.S. federal income tax on such built-in 
gain at the time of our requalification as a RIC.
Item 1A. Risk Factors
Investing in our securities involves a number of significant risks. In addition to the other information contained in 
this Annual Report on Form 10-K, you should consider carefully the following information before making an investment in 
our securities. The risks set out below are not the only risks we face. Additional risks and uncertainties not presently known 
to us or not presently deemed material by us might also impair our operations and performance. If any of the following 
events occur, our business, financial condition and results of operations could be materially and adversely affected. In 
such case, our NAV, the trading price of our common stock and the value of our other securities could decline, and you 
may lose all or part of your investment.
SUMMARY OF RISK FACTORS
The following is a summary of the principal risk factors associated with an investment in our securities. Further 
details regarding each risk included in the below summary list can be found further below.
Table of contents
22

Risks Related to our Business and Structure
• Because our Investment Portfolio is recorded at fair value, there is and will continue to be uncertainty as to the value 
of our portfolio investments.
• Our financial condition and results of operations depends on our ability to effectively manage and deploy capital.
• We are subject to risks associated with the interest rate environment and changes in interest rates will affect our cost of 
capital, net investment income and the value of our investments.
• We face increasing competition for investment opportunities.
• We are dependent upon our key investment personnel for our future success.
• Our success depends on attracting and retaining qualified personnel in a competitive environment.
• Our business model depends to a significant extent upon strong referral relationships.
• Our Board of Directors may change our operating policies and strategies without prior notice or stockholder approval, 
the effects of which may be adverse.
Risks Related to our Investments
• The types of portfolio companies in which we invest involve significant risks and we could lose all or part of our 
investment.
• Economic recessions or downturns could impair our portfolio companies’ performance and defaults by our portfolio 
companies will harm our operating results.
• Rising credit spreads could affect the value of our investments, and rising interest rates make it more difficult for 
portfolio companies to make periodic payments on their loans.
• Inflation could adversely affect the business, results of operations and financial condition of our portfolio companies.
• We may be exposed to higher risks with respect to our investments that include original issue discount or PIK interest.
• The lack of liquidity in our investments may adversely affect our business.
• We may not have the funds or ability to make additional investments in our portfolio companies.
• There may be circumstances where our debt investments could be subordinated to claims of other creditors or we 
could be subject to lender liability claims.
• We generally will not control our portfolio companies.
• Defaults by our portfolio companies will harm our operating results.
• Any unrealized depreciation that we experience in our portfolio may be an indication of future realized losses, which 
could reduce our income and gains available for distribution.
• Prepayments of our debt investments by our portfolio companies could adversely impact our results of operations and 
reduce our return on equity.
• We may be subject to risks associated with “covenant-lite” loans.
• We may not realize gains from our equity investments.
Risks Related to Leverage
• Because we borrow money, the potential for gain or loss on amounts invested in us is magnified and may increase the 
risk of investing in us.
• Substantially all of our assets are subject to security interests under our senior securities and if we default on our 
obligations under our senior securities, we may suffer adverse consequences, including foreclosure on our assets.
• We are subject to risks associated with any revolving credit facility that utilizes a Structured Subsidiary as our interests 
in any Structured Subsidiary are subordinated and we could be prevented from receiving cash on our equity interests 
from a Structured Subsidiary.
Risks Related to our Investment Management Activities
• Our executive officers and employees, through the External Investment Manager, may manage other investment funds 
that operate in the same or a related line of business as we do, and may invest in such funds, which may result in 
significant conflicts of interest.
• We, through the External Investment Manager, derive revenues from managing third-party funds pursuant to 
management agreements that may be terminated.
Risks Related to BDCs
• Operating under the constraints imposed on us as a BDC and RIC may hinder the achievement of our investment 
objectives.
Risks Related to our Securities
• Investing in our securities may involve a high degree of risk.
• Shares of closed-end investment companies, including BDCs, may trade at a discount to their NAV.
Table of contents
23

• We may not be able to pay distributions to our stockholders, our distributions may not grow over time, and a portion of 
distributions paid to our stockholders may be a return of capital.
Risks Related to our SBIC Funds
• We, through the Funds, issue debt securities guaranteed by the SBA and sold in the capital markets. As a result of its 
guarantee of the debt securities, the SBA has fixed dollar claims on the assets of the Funds that are superior to the 
claims of our securities holders.
Federal Income Tax Risks
• We will be subject to corporate-level U.S. federal income tax if we are unable to qualify as a RIC under Subchapter M 
of the Code.
• We may have difficulty paying the distributions required to maintain RIC tax treatment under the Code if we recognize 
income before or without receiving cash representing such income.
General Risk Factors
• Events outside of our control, including public health crises, supply chain disruptions and inflation, could negatively 
affect our portfolio companies and the results of our operations.
• Market conditions may materially and adversely affect debt and equity capital markets in the United States and abroad, 
which may have a negative impact on our business and operations.
• Failure to comply with applicable laws or regulations and changes in laws or regulations governing our operations may 
adversely affect our business or cause us to alter our business strategy.
RISKS RELATED TO OUR BUSINESS AND STRUCTURE
Because our Investment Portfolio is recorded at fair value, there is and will continue to be uncertainty as to the value of 
our portfolio investments.
Under the 1940 Act, we are required to carry our portfolio investments at market value or, if there is no readily 
available market value, at fair value as determined by us pursuant to procedures established and overseen by our Board of 
Directors. Typically, there is not a public market for the securities of the privately held companies in which we invest 
through our LMM and Private Loan investment strategies. As a result, we value these securities quarterly at fair value 
based on inputs from management and a nationally recognized independent financial advisory services firm (on a rotational 
basis) pursuant to Valuation Procedures approved by our Board of Directors. In addition, the market for investments in 
companies that we invest through our Middle Market investment strategy is generally not a liquid market, and therefore, we 
primarily use 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, pursuant to our Valuation Procedures. 
See Note B.1. — Summary of Significant Accounting Policies — Valuation of the Investment Portfolio included in Item 8. 
Consolidated Financial Statements and Supplementary Data of this Annual Report on Form 10-K for a detailed discussion 
of our Investment Portfolio valuation process and procedures.
The determination of fair value and consequently, the amount of unrealized gains and losses in our portfolio, are 
to a certain degree, subjective and dependent on a valuation process approved by our Board of Directors. Certain factors 
that may be considered in determining the fair value of our investments include external events, such as private mergers, 
sales and acquisitions involving comparable companies. Because such valuations, and particularly valuations of securities 
in privately held companies, are inherently uncertain, may fluctuate over short periods of time and may be based on 
estimates, our determinations of fair value may differ materially from the values that would have been used if a ready 
market for these securities existed. Due to this uncertainty, our fair value determinations may cause our NAV on a given 
date to materially understate or overstate the value that we may ultimately realize on one or more of our investments. As a 
result, investors purchasing our securities based on an overstated NAV would pay a higher price than the value of our 
investments might warrant. Conversely, investors selling our securities during a period in which the NAV understates the 
value of our investments may receive a lower price for their securities than the value of our investments might warrant.
Our financial condition and results of operations depends on our ability to effectively manage and deploy capital.
Our ability to achieve our investment objective of maximizing our 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, 
depends on our ability to effectively manage and deploy capital, which depends, in turn, on our investment team’s ability to 
identify, evaluate and monitor, and our ability to finance and invest in, companies that meet our investment criteria.

Accomplishing our investment objective on a cost-effective basis is largely a function of our investment team’s 
handling of the investment process, its ability to provide competent, attentive and efficient services and our access to 
investments offering acceptable terms. In addition to monitoring the performance of our existing investments, members of 
our investment team are also called upon, from time to time, to provide managerial assistance to some of our portfolio 
companies. These demands on their time may distract them or slow the rate of investment.
Even if we are able to grow and build upon our investment operations, any failure to manage our growth 
effectively could have a material adverse effect on our business, financial condition, results of operations and prospects. 
The results of our operations will depend on many factors, including the availability of opportunities for investment, 
readily accessible short and long-term funding alternatives in the financial markets and economic conditions. Furthermore, 
if we cannot successfully operate our business or implement our investment policies and strategies as described herein, it 
could negatively impact our ability to pay dividends.
We are subject to risks associated with the interest rate environment and changes in interest rates will affect our cost of 
capital, net investment income and the value of our investments.
To the extent we borrow money or issue debt securities or preferred stock to make investments, our net investment 
income will depend, in part, upon the difference between the rate at which we borrow funds or pay interest or dividends on 
such debt securities or preferred stock and the rate at which we invest these funds. In addition, many of our debt 
investments and borrowings have floating interest rates that reset on a periodic basis, and many of our investments are 
subject to interest rate floors. As a result, a change in market interest rates could have a material adverse effect on our net 
investment income. In periods of rising interest rates, our cost of funds will increase because the interest rates on the 
amounts borrowed under our credit facilities are floating, and any new fixed rate debt may be issued at higher coupon rates, 
which could reduce our net investment income to the extent any debt investments have either fixed interest rates, or in 
periods when debt investments with floating interest rates are subject to an interest rate floor above then current levels. In 
periods of declining interest rates, our interest income and our net investment income could be reduced as the interest 
income earned on our floating rate debt investments declines and any new fixed rate debt may be issued at lower coupon 
rates. See further discussion and analysis at Item 7A. Quantitative and Qualitative Disclosures about Market Risk.
We can use interest rate risk management techniques in an effort to limit our exposure to interest rate fluctuations. 
Such techniques could include various interest rate hedging activities to the extent permitted by the 1940 Act and 
applicable commodities laws. These activities could limit our ability to participate in the benefits of lower interest rates 
with respect to the hedged borrowings. Adverse developments resulting from changes in interest rates or hedging 
transactions could have a material adverse effect on our business, financial condition and results of operations.
An increase in the market pricing of the spreads charged over index rates on floating rate investments could lead 
to a decline in the fair value of the debt securities we own, which would adversely affect our NAV. Also, an increase in 
interest rates available to investors could make an investment in our common stock less attractive if we are not able to 
increase our dividends, which could reduce the value of our common stock.
We face increasing competition for investment opportunities.
We compete for investments with other investment funds (including private equity funds, debt funds, mezzanine 
funds, collateralized loan obligation funds, or CLOs, BDCs and SBICs), as well as traditional financial services companies 
such as commercial banks and other sources of funding. Many of our competitors are substantially larger and have 
considerably greater financial, technical and marketing resources than we do. For example, some competitors may have a 
lower cost of capital and access to funding sources that are not available to us. In addition, some of our competitors may 
have higher risk tolerances or different risk assessments than we have. These characteristics could allow our competitors to 
consider a wider variety of investments, establish more relationships and offer better pricing and more flexible structuring 
than we are able to do. We may lose investment opportunities if we do not match our competitors’ pricing, terms and 
structure. If we are forced to match our competitors’ pricing, terms and structure, we may not be able to achieve acceptable 
returns on our investments or may bear substantial risk of capital loss. A significant part of our competitive advantage 
stems from the fact that the market for investments in LMM companies is underserved by traditional commercial banks and 
other financing sources. A significant increase in the number and/or the size of our competitors in this target market could 
force us to accept less attractive investment terms. Furthermore, many of our competitors are not subject to the regulatory 
restrictions that the 1940 Act imposes on us as a BDC.

We are dependent upon our key investment personnel for our future success.
We depend on the members of our investment team, particularly Dwayne L. Hyzak, David L. Magdol, Jesse E. 
Morris, Jaime Arreola, K. Colton Braud, III, Damian T. Burke, Samuel A. Cashiola, Diego Fernandez, Nicholas T. 
Meserve and Jonathan B. Montgomery for the identification, review, final selection, structuring, closing and monitoring of 
our investments. These employees have significant investment expertise and relationships that we rely on to implement our 
business plan. Although we have entered into non-compete arrangements with all of our executive officers and other key 
employees, we cannot guarantee that any employees will remain employed with us. If we lose the services of the 
individuals mentioned above, we may not be able to operate our business as we expect, and our ability to compete could be 
harmed, which could cause our operating results to suffer.
Our success depends on attracting and retaining qualified personnel in a competitive environment.
Our growth will require that we retain new investment and administrative personnel in a competitive market. Our 
ability to attract and retain personnel with the requisite credentials, experience and skills depends on several factors 
including, but not limited to, our ability to offer competitive wages, benefits and professional growth opportunities. Many 
of the entities, including investment funds (such as private equity funds, debt funds and mezzanine funds) and traditional 
financial services companies, with which we compete for experienced personnel have greater resources than we have.
The competitive environment for qualified personnel may require us to take certain measures to ensure that we are 
able to attract and retain experienced personnel. Such measures may include increasing the attractiveness of our overall 
compensation packages, altering the structure of our compensation packages through the use of additional forms of 
compensation, or other steps. The inability to attract and retain experienced personnel would have a material adverse effect 
on our business.
Our business model depends to a significant extent upon strong referral relationships.
We expect that members of our management team will maintain their relationships with intermediaries, financial 
institutions, investment bankers, commercial bankers, financial advisors, attorneys, accountants, consultants and other 
individuals within our network, and we will rely to a significant extent upon these relationships to provide us with potential 
investment opportunities. If our management team fails to maintain its existing relationships or develop new relationships 
with sources of investment opportunities, we will not be able to grow our Investment Portfolio. In addition, individuals 
with whom members of our management team have relationships are not obligated to provide us with investment 
opportunities, and, therefore, there is no assurance that such relationships will generate investment opportunities for us.
Our Board of Directors may change our investment objective, operating policies and strategies without prior notice or 
stockholder approval, the effects of which may be adverse.
Our Board of Directors has the authority, except as otherwise provided in the 1940 Act, to modify or waive our 
investment objective, current operating policies, investment criteria and strategies without prior notice and without 
stockholder approval. However, absent stockholder approval, we may not change the nature of our business so as to cease 
to be regulated as, or withdraw our election as, a BDC. We cannot predict the effect any changes to our investment 
objective, current operating policies, investment criteria and strategies would have on our business, NAV, operating results 
and value of our stock. However, the effects might be material and adverse, which could negatively affect our business and 
impair our ability to pay interest and principal payments to holders of our debt instruments and to make distributions to our 
stockholders and cause our investors to lose all or part of their investment in us.

We are a non-diversified investment company within the meaning of the 1940 Act, and therefore we are not limited with 
respect to the proportion of our assets that may be invested in securities of a single issuer.
We are classified as a non-diversified investment company within the meaning of the 1940 Act, which means that 
we are not limited by the 1940 Act with respect to the proportion of our assets that we may invest in securities of a single 
issuer. Under the 1940 Act, a “diversified” investment company is required to invest at least 75% of the value of its total 
assets in cash and cash items, government securities, securities of other investment companies and other securities limited 
in respect of any one issuer to an amount not greater than 5% of the value of the total assets of such company and no more 
than 10% of the outstanding voting securities of such issuer. As a non-diversified investment company, we are not subject 
to this requirement. To the extent that we assume large positions in the securities of a small number of issuers, our NAV 
may fluctuate to a greater extent than that of a diversified investment company as a result of changes in the financial 
condition or the market’s assessment of the issuer. We may also be more susceptible to any single economic or regulatory 
occurrence than a diversified investment company. Beyond our RIC asset diversification requirements and any 
requirements under our financing arrangements, we do not have fixed guidelines for diversification, and our investments 
could be concentrated in relatively few portfolio companies. See Risk Factors — Federal Income Tax Risks — We will be 
subject to corporate-level U.S. federal income tax if we are unable to qualify as a RIC under Subchapter M of the Code. 
Although we have historically operated as a non-diversified investment company within the meaning of the 1940 Act, our 
investment portfolio may, from time to time, be comprised of assets that could permit us to qualify as a “diversified” 
investment company under the 1940 Act. To the extent that we operate as a non-diversified investment company, we may 
be subject to greater risk.
We and our portfolio companies may maintain cash balances at financial institutions that exceed federally insured 
limits and may otherwise be materially affected by adverse developments affecting the financial services industry, such 
as actual events or concerns involving liquidity, defaults or non-performance by financial institutions or transactional 
counterparties.
 Cash held by us and by our portfolio companies in non-interest-bearing and interest-bearing operating accounts 
may exceed the Federal Deposit Insurance Corporation (“FDIC”) insurance limits. If such banking institutions were to fail, 
we or our portfolio companies could lose all or a portion of those amounts held in excess of such insurance limitations. In 
addition, actual events involving limited liquidity, defaults, non-performance or other adverse developments that affect 
financial institutions, transactional counterparties or other companies in the financial services industry or the financial 
services industry generally, or concerns or rumors about any events of these kinds or other similar risks, have in the past 
and may in the future lead to market-wide liquidity problems, which could adversely affect our and our portfolio 
companies’ business, financial condition, results of operations and prospects.
Although we assess our portfolio companies’ banking relationships as we believe necessary or appropriate, our 
and our portfolio companies’ access to funding sources and other credit arrangements in amounts adequate to finance or 
capitalize our respective current and projected future business operations could be significantly impaired by factors that 
affect us or our portfolio companies, the financial institutions with which we or our portfolio companies have arrangements 
directly or the financial services industry or economy in general. These factors could include, among others, events such as 
liquidity constraints or failures, the ability to perform obligations under various types of financial, credit or liquidity 
agreements or arrangements, disruptions or instability in the financial services industry or financial markets or concerns or 
negative expectations about the prospects for companies in the financial services industry. These factors could involve 
financial institutions or financial services industry companies with which we or our portfolio companies have financial or 
business relationships, but could also include factors involving financial markets or the financial services industry 
generally.
In addition, investor concerns regarding the U.S. or international financial systems could result in less favorable 
commercial financing terms, including higher interest rates or costs and tighter financial and operating covenants or 
systemic limitations on access to credit and liquidity sources, thereby making it more difficult for us or our portfolio 
companies to acquire financing on acceptable terms or at all.

We are subject to risks related to corporate social responsibility.
Our business faces increasing public scrutiny related to environmental, social and governance (“ESG”) activities. 
We risk damage to our brand and reputation if we fail to act responsibly in a number of areas, such as diversity and 
inclusion, environmental stewardship, support for local communities, corporate governance and transparency and 
considering ESG factors in our investment processes. Adverse incidents with respect to ESG activities could impact the 
value of our brand, the cost of our operations and relationships with investors, all of which could adversely affect our 
business and results of operations. Additionally, new regulatory initiatives related to ESG could adversely affect our 
business.
RISKS RELATED TO OUR INVESTMENTS
The types of portfolio companies in which we invest involve significant risks and we could lose all or part of our 
investment.
Investing in the types of companies that comprise our portfolio companies exposes us to a number of significant 
risks. Among other things, these companies:
•
may have limited financial resources and may be unable to meet their obligations under their debt instruments 
that we hold, which may be accompanied by a deterioration in the value of any collateral and a reduction in 
the likelihood of us realizing any guarantees from subsidiaries or affiliates of our portfolio companies that we 
may have obtained in connection with our investment, as well as a corresponding decrease in the value of our 
investments;
•
may have shorter operating histories, narrower product lines, smaller market shares and/or significant 
customer concentrations than larger businesses, which tend to render them more vulnerable to competitors’ 
actions and market conditions, as well as general economic downturns;
•
are more likely to depend on the management talents and efforts of a small group of persons; therefore, the 
death, disability, resignation, termination or significant under-performance of one or more of these persons 
could have a material adverse impact on our portfolio company and, in turn, on us;
•
generally have less predictable operating results, may from time to time be parties to litigation, may be 
engaged in rapidly changing businesses with products subject to a substantial risk of obsolescence, and may 
require substantial additional capital to support their operations, finance expansion or maintain their 
competitive position; and
•
generally have less publicly available information about their businesses, operations and financial condition. 
We are required to rely on the ability of our management team and investment professionals to obtain 
adequate information to evaluate the potential returns from investing in these companies. If we are unable to 
uncover all material information about these companies, we may not make a fully informed investment 
decision, and may lose all or part of our investment.
In addition certain of our officers and directors may serve as directors on the boards of our portfolio companies. 
To the extent that litigation arises out of our investments in these companies, our officers and directors may be named as 
defendants in such litigation, which could result in an expenditure of funds (through our indemnification of such officers 
and directors) and the diversion of management time and resources.
Economic recessions or downturns could impair our portfolio companies’ performance and defaults by our portfolio 
companies will harm our operating results.
Many of our portfolio companies are susceptible to economic slowdowns or recessions and could be unable to 
repay our loans during these periods. Therefore, the number of non-performing assets are likely to increase and the value of 
our portfolio is likely to decrease during these periods. Adverse economic conditions could decrease the value of collateral 
securing any of our loans and the value of any equity investments. A severe recession could further decrease the value of 
such collateral and result in losses of value in our portfolio and a decrease in our revenues, net income, assets and net 
worth. Economic slowdowns or recessions could lead to financial losses in our portfolio and a decrease in revenues, net 
income and assets. Unfavorable economic conditions also could increase our funding costs, limit our access to the capital 
markets or result in a decision by lenders not to extend credit to us. These events could prevent us from maintaining or 
increasing the level of our investments and harm our operating results.

Any deterioration of general economic conditions could lead to significant declines in corporate earnings or loan 
performance, and the ability of corporate borrowers to service their debt, any of which could trigger a period of global 
economic slowdown, and have an adverse impact on our performance and financial results, and the value and the liquidity 
of our investments. In an economic downturn, we could have non-performing assets or an increase in non-performing 
assets, and we would anticipate that the value of our portfolio would decrease during these periods. Failure to satisfy 
financial or operating covenants imposed by lenders, including us, to a portfolio company could lead to defaults and, 
potentially, acceleration of payments on such loans and foreclosure on the assets representing collateral for the portfolio 
company’s obligations. Cross default provisions under other agreements could be triggered and thus limit the portfolio 
company’s ability to satisfy its obligations under any debt that we hold and affect the value of any securities we own. We 
would expect to incur expenses to the extent necessary to seek recovery upon default or to negotiate new terms with a 
portfolio company following or in anticipation of a default.
Rising credit spreads could affect the value of our investments, and rising interest rates make it more difficult for 
portfolio companies to make periodic payments on their loans.
Some of our portfolio investments are debt securities that bear interest at variable rates and may be negatively 
affected by changes in market interest rates. Rising interest rates make it more difficult for borrowers to repay debt, which 
could increase the risk of payment defaults and cause the portfolio companies to defer or cancel needed investment. Any 
failure of one or more portfolio companies to repay or refinance its debt at or prior to maturity or the inability of one or 
more portfolio companies to make ongoing payments following an increase in contractual interest rates could have a 
material adverse effect on our business, financial condition, results of operations and cash flows. The value of our 
securities could also be reduced from an increase in market credit spreads as rates available to investors could make an 
investment in our securities less attractive than alternative investments.
Conversely, decreases in market interest rates could negatively impact the interest income from our variable rate 
debt investments while the interest we pay on our fixed rate debt securities does not change. A decrease in market interest 
rates may also have an adverse impact on our returns by requiring us to accept lower yields on our debt investments and by 
increasing the risk that our portfolio companies will prepay our debt investments, resulting in the need to redeploy capital 
at potentially lower rates. 
Inflation could adversely affect the business, results of operations and financial condition of our portfolio companies.
Certain of our portfolio companies are in industries that could be impacted by inflation. If such portfolio 
companies are unable to pass any increases in their costs of operations along to their customers, it could adversely affect 
their operating results and impact their ability to pay dividends on our equity investments and/or interest and principal on 
our loans, particularly if interest rates rise in response to inflation. In addition, any projected future decreases in our 
portfolio companies’ operating results due to inflation could adversely impact the fair value of those investments. Any 
decreases in the fair value of our investments could result in future realized or unrealized losses and therefore reduce our 
net increase (decrease) in net assets resulting from operations.
We may be exposed to higher risks with respect to our investments that include original issue discount or PIK interest.
Our investments may include original issue discount and contractual PIK interest, which represents contractual 
interest added to a loan balance and due at the end of such loan’s term. To the extent original issue discount or PIK interest 
constitute a portion of our income, we are exposed to typical risks associated with such income being required to be 
included in taxable and accounting income prior to receipt of cash, including the following:
•
original issue discount and PIK instruments may have higher yields, which reflect the payment deferral and 
credit risk associated with these instruments;
•
cash distributions paid to investors representing original issue discount income may be effectively paid from 
offering proceeds or borrowings during any given period; thus, although the source for the cash used to pay a 
distribution of original issue discount income may come from the cash invested by investors, or our 
borrowings, the 1940 Act does not require that investors be given notice of this fact;
•
original issue discount and PIK instruments may have unreliable valuations because their continuing accruals 
require continuing judgments about the collectability of the deferred payments and the value of the collateral; 
and
Table of contents
29

•
original issue discount and PIK instruments may represent a higher credit risk than coupon loans; even if the 
conditions for income accrual under U.S. GAAP are satisfied, a borrower could still default when actual 
payment is due upon the maturity of such loan.
The lack of liquidity in our investments may adversely affect our business.
We generally invest in companies whose securities are not publicly traded and whose securities will be subject to 
legal and other restrictions on resale or will otherwise be less liquid than publicly traded securities. The illiquidity of these 
investments may make it difficult for us to sell these investments when desired. In addition, if we are required to liquidate 
all or a portion of our portfolio quickly, we may realize significantly less than the value at which we had previously 
recorded these investments. As a result, we do not expect to achieve liquidity in our investments in the near-term. The 
illiquidity of most of our investments may make it difficult for us to dispose of them at a favorable price and, as a result, 
we may suffer losses.
We may not have the funds or ability to make additional investments in our portfolio companies.
We may not have the funds or ability to make additional investments in our portfolio companies. After our initial 
investment in a portfolio company, we may be called upon from time to time to provide additional funds to such company 
or have the opportunity to increase our investment through the extension of additional loans, the exercise of a warrant to 
purchase equity securities, or the funding of additional equity investments. There is no assurance that we will make, or will 
have sufficient funds to make, follow-on investments. Any decisions not to make a follow-on investment or any inability 
on our part to make such an investment may have a negative impact on a portfolio company in need of such an investment, 
may result in a missed opportunity for us to increase our participation in a successful operation, may reduce our ability to 
protect an existing investment or may reduce the expected yield on the investment.
There may be circumstances where our debt investments could be subordinated to claims of other creditors or we could 
be subject to lender liability claims.
Our portfolio companies may have, or may be permitted to incur, other debt that ranks equally with, or senior to, 
the debt in which we invest. By their terms, such debt instruments may entitle the holders to receive payment of interest or 
principal on or before the dates on which we are entitled to receive payments with respect to the debt instruments in which 
we invest. Also, in the event of insolvency, liquidation, dissolution, reorganization or bankruptcy of a portfolio company, 
holders of debt instruments ranking senior to our investment in that portfolio company would typically be entitled to 
receive payment in full before we receive any distribution. After repaying such senior creditors, such portfolio company 
may not have any remaining assets to use for repaying its obligation to us. In the case of debt ranking equally with debt 
instruments in which we invest, we would have to share on an equal basis any distributions with other creditors holding 
such debt in the event of an insolvency, liquidation, dissolution, reorganization or bankruptcy of the relevant portfolio 
company.
Even if our investment is structured as a senior-secured loan, principles of equitable subordination, as defined by 
existing case law, could lead a bankruptcy court to subordinate all or a portion of our claim to that of other creditors and 
transfer any lien securing such subordinated claim to the bankruptcy estate. The principles of equitable subordination 
defined by case law have generally indicated that a claim may be subordinated only if its holder is guilty of misconduct or 
where the senior loan is re-characterized as an equity investment and the senior lender has actually provided significant 
managerial assistance to the bankrupt debtor. We may also be subject to lender liability claims for actions taken by us with 
respect to a borrower’s business or instances where we exercise control over the borrower. It is possible that we could 
become subject to a lender liability claim, including as a result of actions taken in rendering significant managerial 
assistance or actions to compel and collect payments from the borrower outside the ordinary course of business.
We generally will not control our portfolio companies.
We do not, and do not expect to, control the decision making in many of our portfolio companies, even though we 
may have board representation or board observation rights, and our debt agreements may contain certain restrictive 
covenants. As a result, we are subject to the risk that a portfolio company in which we invest will make business decisions 
with which we disagree and the management of such company will take risks or otherwise act in ways that do not serve our 
interests as debt investors or minority equity holders. Due to the lack of liquidity for our investments in non-traded 
companies, we may not be able to dispose of our interests in our portfolio companies as readily as we would like or at an 
appropriate valuation. As a result, a portfolio company may make decisions that would decrease the value of our portfolio 
holdings.

Defaults by our portfolio companies will harm our operating results.
A portfolio company’s failure to satisfy financial or operating covenants imposed by us or other lenders could lead 
to non-payment of interest and other defaults and, potentially, termination of its loans and foreclosure on its secured assets, 
which could trigger cross-defaults under other agreements and jeopardize a portfolio company’s ability to meet its 
obligations under the debt or equity securities that we hold. We may incur expenses to the extent necessary to seek 
recovery upon default or to negotiate new terms, which may include the waiver of certain financial covenants, with a 
defaulting portfolio company.
Any unrealized depreciation that we experience in our portfolio may be an indication of future realized losses, which 
could reduce our income and gains available for distribution.
As a BDC, we are required to carry our investments at market value or, if no market value is ascertainable, at the 
fair value as determined in accordance with our Valuation Procedures adopted pursuant to Rule 2a-5 under the 1940 Act. 
Decreases in the market values or fair values of our investments will be recorded as unrealized depreciation. Any 
unrealized depreciation in our portfolio could be an indication of a portfolio company’s inability to meet its repayment 
obligations to us with respect to affected loans or a potential impairment of the value of affected equity investments. 
This could result in realized losses in the future and ultimately in reductions of our income and gains available for 
distribution in future periods.
Prepayments of our debt investments by our portfolio companies could adversely impact our results of operations and 
reduce our return on equity.
We are subject to the risk that the investments we make in our portfolio companies may be repaid prior to 
maturity. When this occurs, we will generally reinvest these proceeds in temporary investments, pending their future 
investment in new portfolio companies. These temporary investments will typically have substantially lower yields than the 
debt being prepaid and we could experience significant delays in reinvesting these amounts. Any future investment in a 
new portfolio company may also be at lower yields than the debt that was repaid. As a result, our results of operations 
could be materially adversely affected if one or more of our portfolio companies elect to prepay amounts owed to us. 
Additionally, prepayments could negatively impact our return on equity, which could result in a decline in the market price 
of our securities.
We may be subject to risks associated with “covenant-lite” loans.
Some of the loans in which we invest may be “covenant-lite” loans, which means the loans contain fewer 
maintenance covenants than other loans (in some cases, none) and do not include terms which allow the lender to monitor 
the performance of the borrower and declare a default if certain criteria are breached. Generally, “covenant-lite” loans 
provide borrower companies more freedom to negatively impact lenders because their covenants are incurrence-based, 
which means they are only tested and can only be breached following an affirmative action of the borrower, rather than by 
a deterioration in the borrower’s financial condition. To the extent we invest in covenant-lite loans, we may have fewer 
rights against a borrower and may have a greater risk of loss on such investments as compared to investments in loans with 
finance maintenance covenants.
We may not realize gains from our equity investments.
Certain investments that we have made in the past and may make in the future include warrants or other equity 
securities. Investments in equity securities involve a number of significant risks, including the risk of further dilution as a 
result of additional issuances, inability to access additional capital and failure to pay current distributions. Investments in 
preferred securities involve special risks, such as the risk of deferred distributions, credit risk, illiquidity and limited voting 
rights. In addition, we may from time to time make non-control, equity investments in portfolio companies. Our goal is 
ultimately to realize gains upon our disposition of such equity interests. However, these equity interests may not appreciate 
in value and, in fact, may decline in value. Accordingly, we may not be able to realize gains from our equity interests, and 
any gains that we do realize on the disposition of any equity interests may not be sufficient to offset any other losses we 
experience. We also may be unable to realize any value if a portfolio company does not have a liquidity event, such as a 
sale of the business, recapitalization or public offering, which would allow us to sell the underlying equity interests. We 
often seek puts or similar rights to give us the right to sell our equity securities back to the portfolio company issuer; 
however, we may be unable to exercise these put rights for the consideration provided in our investment documents if the 
issuer is in financial distress.

Our investments in foreign securities may involve significant risks in addition to the risks inherent in U.S. investments.
Our investment strategy contemplates potential investments in debt securities of foreign companies. Investing in 
foreign companies may expose us to additional risks not typically associated with investing in securities of U.S. companies. 
These risks include changes in exchange control regulations, political and social instability, expropriation, imposition of 
foreign taxes, less liquid markets and less available information than is generally the case in the U.S., higher transaction 
costs, less government supervision of exchanges, brokers and issuers, less developed bankruptcy laws, difficulty in 
enforcing contractual obligations, lack of uniform accounting and auditing standards and greater price volatility.
Although most of our investments will be U.S. dollar denominated, any investments denominated in a foreign 
currency will be subject to the risk that the value of a particular currency will change in relation to one or more other 
currencies. Among the factors that may affect currency values are trade balances, the level of short-term interest rates, 
differences in relative values of similar assets in different currencies, long-term opportunities for investment and capital 
appreciation, and political developments.
RISKS RELATED TO LEVERAGE
Because we borrow money, the potential for gain or loss on amounts invested in us is magnified and may increase the 
risk of investing in us.
Borrowings, also known as leverage, magnify the potential for loss on investments in our indebtedness and gain or 
loss on investments in our equity capital. As we use leverage to partially finance our investments, you will experience 
increased risks of investing in our securities. Accordingly, any event that adversely affects the value of an investment 
would be magnified to the extent we use leverage. Such events could result in a substantial loss to us, which would be 
greater than if leverage had not been used. In addition, our investment objectives are dependent on the continued 
availability of leverage at attractive relative interest rates.
We may also borrow from banks and other lenders and may issue debt securities or enter into other types of 
borrowing arrangements in the future. Lenders of these senior securities will have fixed dollar claims on our assets that are 
superior to the claims of our common stockholders, and we would expect such lenders to seek recovery against our assets 
in the event of a default. We have the ability to pledge up to 100% of our assets and can grant a security interest in all of 
our assets under the terms of any debt instruments we could enter into with lenders. The terms of our existing indebtedness 
require us to comply with certain financial and operational covenants, and we expect similar covenants in future debt 
instruments. Failure to comply with such covenants could result in a default under the applicable credit facility or debt 
instrument if we are unable to obtain a waiver from the applicable lender or holder, and such lender or holder could 
accelerate repayment under such indebtedness and negatively affect our business, financial condition, results of operations 
and cash flows. In addition, under the terms of any credit facility or other debt instrument we enter into, in the event of a 
default, we are likely to be required by its terms to use the net proceeds of any investments that we sell to repay a portion of 
the amount borrowed under such facility or instrument before applying such net proceeds to any other uses. See Item 7. 
Management’s Discussion and Analysis of Financial Condition and Results of Operations — Liquidity and Capital 
Resources — Capital Resources for a discussion regarding our outstanding indebtedness. 
If the value of our assets decreases, leveraging would cause NAV to decline more sharply than it otherwise would 
have had we not leveraged our business. Similarly, any decrease in our income would cause net investment income to 
decline more sharply than it would have had we not leveraged our business. Such a decline could negatively affect our 
ability to pay common stock dividends, scheduled debt payments or other payments related to our securities. 
Illustration: The following table illustrates the effect of leverage on returns from an investment in our common 
stock assuming various annual returns, net of expenses. The calculations in the table below are hypothetical and actual 
returns may be higher or lower than those appearing below.

Our ability to achieve our investment objective may depend in part on our ability to access additional leverage on 
favorable terms and there can be no assurance that such additional leverage can in fact be achieved. If we are unable to 
obtain leverage or if the interest rates of such leverage are not attractive, we could experience diminished returns. The 
number of leverage providers and the total amount of financing available could decrease or remain static.
Substantially all of our assets are subject to security interests under our senior securities and if we default on our 
obligations under our senior securities, we may suffer adverse consequences, including foreclosure on our assets.
Substantially all of our assets are currently pledged as collateral under our secured debt obligations. If we default 
on our obligations under our secured debt obligations, our lenders may have the right to foreclose upon and sell, or 
otherwise transfer, the collateral subject to their security interests or their superior claim. In such event, we may be forced 
to sell our investments to raise funds to repay our outstanding borrowings in order to avoid foreclosure and these forced 
sales may be at times and at prices we would not consider advantageous. Moreover, such deleveraging of our company 
could significantly impair our ability to effectively operate our business in the manner in which we have historically 
operated. As a result, we could be forced to curtail or cease new investment activities and lower or eliminate the dividends 
that we have historically paid to our stockholders. In addition, if the lenders exercise their right to sell the assets pledged 
under our secured debt obligations, such sales may be completed at distressed sale prices, thereby diminishing or 
potentially eliminating the amount of cash available to us after repayment of the amounts of outstanding borrowings.
If our operating performance declines and we are not able to generate sufficient cash flow to service our debt 
obligations, we may in the future need to refinance or restructure our debt, sell assets, reduce or delay capital investments, 
seek to raise additional capital or seek to obtain waivers from the required lenders under our debt obligations to avoid being 
in default. If we are unable to implement one or more of these alternatives, we may not be able to meet our payment 
obligations under our debt obligations. If we breach our covenants under our debt obligations and seek a waiver, we may 
not be able to obtain a waiver from the required lenders or debt holders. If this occurs, we would be in default under our 
debt obligations, the lenders or debt holders could exercise their rights as described above, and we could be forced into 
bankruptcy or liquidation. If we are unable to repay debt, lenders having secured obligations could proceed against the 
collateral securing the debt. Because certain of our debt obligations have customary cross-default provisions, if the 
indebtedness under our debt obligations is accelerated, we may be unable to repay or finance the amounts due.
We are subject to risks associated with any revolving credit facility that utilizes a Structured Subsidiary as our interests 
in any Structured Subsidiary are subordinated and we could be prevented from receiving cash on our equity interests 
from a Structured Subsidiary.
We own directly or indirectly 100% of the equity interests in MSCC Funding I, LLC (“MSCC Funding”), a 
special purpose Structured Subsidiary utilized in our senior secured special purpose vehicle revolving credit facility (the 
“SPV Facility”). We consolidate the financial statements of MSCC Funding in our consolidated financial statements and 
treat the indebtedness under the SPV Facility as our leverage. Our interest in MSCC Funding is subordinated in priority of 
payment to every other obligation of MSCC Funding and is subject to certain payment restrictions set forth in the SPV 
Facility.
We receive cash from MSCC Funding only to the extent that we receive distributions on our equity interests 
therein. MSCC Funding could make distributions on its equity interests only to the extent permitted by the payment priority 
provisions of the SPV Facility. The SPV Facility generally provides that payments on the respective interests could not be 
made on any payment date unless all amounts owing to the lenders and other secured parties are paid in full. In addition, if 
MSCC Funding does not meet the asset coverage tests or the interest coverage test set forth in the agreement governing the 
SPV Facility, a default could occur. In the event of a default under the SPV Facility credit agreement, cash would be 
diverted from us to pay the applicable lenders and other secured parties in amounts sufficient to cause such tests to be 
satisfied. In the event that we fail to receive cash from MSCC Funding, we could be unable to make distributions to our 
stockholders in amounts sufficient to maintain our status as a RIC, or at all. We also could be forced to sell investments in 
portfolio companies at less than their fair value in order to continue making such distributions. We cannot assure you that 
distributions on the assets held by MSCC Funding will be sufficient to make any distributions to us or that such 
distributions will meet our expectations.
Our equity interest in MSCC Funding ranks behind all of the secured and unsecured creditors, known or unknown, 
including the lenders in the SPV Facility. Consequently, to the extent that the value of MSCC Funding’s portfolio of loan 
investments has been reduced as a result of conditions in the credit markets, defaulted loans, capital gains and losses on the 
underlying assets, prepayment or changes in interest rates, the returns on our investments in MSCC Funding could be 
reduced. Accordingly, our investments in MSCC Funding could be subject to up to 100% loss.

The ability to sell investments held by a Structured Subsidiary is limited.
The credit agreement governing the SPV Facility places significant restrictions on our ability, as servicer, to sell 
investments. As a result, there could be times or circumstances during which we are unable to sell investments or take other 
actions that might be in our best interests.
We may invest in derivatives or other assets that expose us to certain risks, including market risk, liquidity risk and 
other risks similar to those associated with the use of leverage. 
We may invest in derivatives and other assets that are subject to many of the same types of risks related to the use 
of leverage. Derivative transactions, if any, will generally create leverage for us and involve significant risks. The primary 
risks related to derivative transactions include counterparty, correlation, liquidity, leverage, volatility, over-the-counter 
trading, operational and legal risks. In addition, a small investment in derivatives could have a large potential impact on our 
performance, effecting a form of investment leverage on our portfolio. In certain types of derivative transactions, we could 
lose the entire amount of our investment; in other types of derivative transactions the potential loss is theoretically 
unlimited.
Under SEC Rule 18f-4 under the 1940 Act (“Rule 18f-4”), related to use of derivatives, short sales, reverse 
repurchase agreements and certain other transactions by BDCs, we are permitted to enter into derivatives and other 
transactions that create future payment or delivery obligations, including short sales, notwithstanding the senior security 
provision of the 1940 Act if we comply with certain value-at-risk leverage limits, adopt a derivatives risk management 
program and implement board oversight and reporting requirements or otherwise comply with a “limited derivatives users” 
exception. Rule 18f-4 also permits us to enter into reverse repurchase agreements or similar financing transactions 
notwithstanding the senior security provision of the 1940 Act if we aggregate the amount of indebtedness associated with 
our reverse repurchase agreements or similar financing transactions with the aggregate amount of any other senior 
securities representing indebtedness when calculating the asset coverage ratios as discussed herein. In addition, we are 
permitted to invest in a security on a when-issued or forward-settling basis, or with a non-standard settlement cycle, and the 
transaction will be deemed not to involve a senior security under the 1940 Act, provided that (i) we intend to physically 
settle the transaction and (ii) the transaction will settle within 35 days of its trade date (the “Delayed-Settlement Securities 
Provision”). We may otherwise engage in such transaction as a “derivatives transaction” for purposes of compliance with 
the rule. Furthermore, we are permitted to enter into an unfunded commitment agreement, and such unfunded commitment 
agreement will not be subject to the asset coverage requirements under the 1940 Act if we reasonably believe, at the time 
we enter into such agreement, that we will have sufficient cash and cash equivalents to meet our obligations with respect to 
all such agreements as they come due. We cannot predict the effects of these requirements.
We have adopted updated policies and procedures in compliance with Rule 18f-4. We expect to qualify as a 
“limited derivatives user.” Future legislation or rules may modify how we treat derivatives and other financial 
arrangements for purposes of our compliance with the leverage limitations of the 1940 Act, which may be materially 
adverse to us and our investors.
RISKS RELATED TO OUR INVESTMENT MANAGEMENT ACTIVITIES
Our executive officers and employees, through the External Investment Manager, may manage other investment funds 
that operate in the same or a related line of business as we do, and may invest in such funds, which may result in 
significant conflicts of interest.
Our executive officers and employees, through the External Investment Manager, may manage other investment 
funds or assets for other clients that operate in the same or a related line of business as we do, and which funds may be 
invested in by us and/or our executive officers and employees. Accordingly, they may have obligations to, or pecuniary 
interests in, such other entities, and the fulfillment of such obligations may not be in the best interests of us or our 
stockholders and may create conflicts of interest. 
Table of contents
34

We have made and, in the future, intend to make co-investments with other funds or clients advised by the 
External Investment Manager in accordance with the conditions of an exemptive relief order from the SEC permitting such 
co-investment transactions. 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 and, 
if it is appropriate, to propose an allocation of the investment opportunity between such other parties. As a consequence, it 
may be more difficult for us to maintain or increase the size of our Investment Portfolio in the future. Although we will 
endeavor to allocate investment opportunities in a fair and equitable manner, including in accordance with the conditions 
set forth in the order issued by the SEC when relying on such order, we may face conflicts in allocating investment 
opportunities between us and other funds and accounts managed by the External Investment Manager. Because the 
External Investment Manager may receive performance-based fee compensation from other funds and accounts it manages, 
this may provide the Company and the External Investment Manager an incentive to allocate opportunities to other funds 
and accounts the External Investment Manager manages, instead of us. We and the External Investment Manager have 
implemented an allocation policy to ensure the equitable distribution of investment opportunities and, as a result, we may 
be unable to participate in certain investments based upon such allocation policy.
We, through the External Investment Manager, derive revenues from managing third-party funds pursuant to 
management agreements that may be terminated.
The External Investment Manager earns management fees based on the assets of the funds or other clients under 
management and may earn incentive fees, or a carried interest, based on the performance of the funds or accounts managed. 
The terms of fund investment management agreements generally give the manager of the fund and the fund itself the right 
to terminate the management agreement in certain circumstances. With respect to funds that are not exempt from regulation 
under the 1940 Act, the fund’s investment management agreement must be approved annually by (a) such fund’s board of 
directors or by the vote of a majority of such fund’s stockholders and (b) the majority of the independent members of such 
fund’s board of directors and, in certain cases, by its stockholders, as required by law. The funds’ investment management 
agreements can also be terminated by the majority of such fund’s stockholders. Termination of any such management 
agreements would reduce the fees we earn from the relevant funds or other clients through the External Investment 
Manager, which could have a material adverse effect on our results of operations. 
RISKS RELATED TO BDCs
Failure to maintain our status as a BDC would reduce our operating flexibility.
If we do not remain a BDC, we might be regulated as a closed-end investment company under the 1940 Act, 
which would subject us to substantially more regulatory restrictions under the 1940 Act and correspondingly decrease our 
operating flexibility.
Operating under the constraints imposed on us as a BDC and RIC may hinder the achievement of our investment 
objectives.
The 1940 Act and the Code impose numerous constraints on the operations of BDCs and RICs that do not apply to 
certain of the other investment vehicles that we may compete with. BDCs are required, for example, to invest at least 70% 
of their total assets in certain qualifying assets, including U.S. private or thinly traded public companies, cash, cash 
equivalents, U.S. government securities and other high-quality debt instruments that mature in one year or less from the 
date of investment. Moreover, qualification for taxation as a RIC requires satisfaction of source-of-income, asset 
diversification and distribution requirements. Operating under these constraints may hinder our ability to take advantage of 
attractive investment opportunities and to achieve our investment objective. Any failure to do so could subject us to 
enforcement action by the SEC, cause us to fail to satisfy the requirements associated with RIC status and subject us to 
entity-level corporate income taxation, cause us to fail the 70% test described above or otherwise have a material adverse 
effect on our business, financial condition or results of operations.
We may be precluded from investing in what we believe are attractive investments if such investments are not 
qualifying assets for purposes of the 1940 Act. If we do not invest a sufficient portion of our assets in qualifying assets, we 
will be prohibited from making any additional investment that is not a qualifying asset and could be forced to forgo 
attractive investment opportunities. Similarly, these rules could prevent us from making follow-on investments in existing 
portfolio companies (which could result in the dilution of our position).

35

If we fail to maintain our status as a BDC, we might be regulated as a closed-end investment company that is 
required to register under the 1940 Act, which would subject us to additional regulatory restrictions and significantly 
decrease our operating flexibility. In addition, any such failure could cause an event of default under any outstanding 
indebtedness we might have, which could have a material adverse effect on our business, financial condition or results of 
operations.
Regulations governing our operation as a BDC will affect our ability to, and the way in which we, raise additional 
capital.
Our business will require capital to operate and grow. We may acquire such additional capital from the following 
sources:
Senior Securities
We may issue debt securities or preferred stock and/or borrow money from banks or other financial institutions, 
which we refer to collectively as senior securities. As a result of issuing senior securities, we will be exposed to additional 
risks, including the following:
•
Prior to the approval of our stockholders, under the provisions of the 1940 Act we were permitted, as a BDC, 
to issue senior securities only in amounts such that our BDC asset coverage ratio, as defined in the 1940 Act, 
equaled at least 200% immediately after each issuance of senior securities. Following the approval of our 
stockholders of the reduced asset coverage requirements in Section 61(a)(2) of the 1940 Act and subject to 
our compliance with certain disclosure requirements, effective as of May 3, 2022, under the provisions of the 
1940 Act, we are permitted to issue senior securities in amounts such that our BDC asset coverage ratio, as 
defined in the 1940 Act, equals at least 150% after each issuance of senior securities. If the value of our assets 
declines, we may be unable to satisfy this test. If that happens, we will be prohibited from issuing debt 
securities or preferred stock and/or borrowing money from banks or other financial institutions and may not 
be permitted to declare a cash dividend or make any cash distribution to stockholders or repurchase shares 
until such time as we satisfy this test.
•
Any amounts that we use to service our debt or make payments on preferred stock will not be available for 
dividends to our common stockholders.
•
It is likely that any senior securities or other indebtedness we issue will be governed by an indenture or other 
instrument containing covenants restricting our operating flexibility. Additionally, some of these securities or 
other indebtedness may be rated by rating agencies, and in obtaining a rating for such securities and other 
indebtedness, we may be required to abide by operating and investment guidelines that further restrict 
operating and financial flexibility.
•
We and, indirectly, our stockholders will bear the cost of issuing and servicing such securities and other 
indebtedness.
•
Preferred stock or any convertible or exchangeable securities that we issue in the future may have rights, 
preferences and privileges more favorable than those of our common stock, including separate voting rights 
and could delay or prevent a transaction or a change in control to the detriment of the holders of our common 
stock.
•
Any unsecured debt issued by us would generally rank (i) pari passu with our current and future unsecured 
indebtedness and effectively subordinated to all of our existing and future secured indebtedness, to the extent 
of the value of the assets securing such indebtedness, and (ii) structurally subordinated to all existing and 
future indebtedness and other obligations of any of our subsidiaries.

Additional Common Stock
We are not generally able to issue and sell our common stock at a price below NAV per share. We may, however, 
sell our common stock, warrants, options or rights to acquire our common stock, at a price below the current NAV per 
share of the common stock if our Board of Directors determines that such sale is in the best interests of our stockholders, 
and our stockholders approve such sale. See Risk Factors — Risks Related to our Securities — Stockholders may incur 
dilution if we sell shares of our common stock in one or more offerings at prices below the then current NAV per share of 
our common stock or issue securities to subscribe to, convert to or purchase shares of our common stock. for a discussion 
related to us issuing shares of our common stock below NAV. Our stockholders have authorized us to issue warrants, 
options or rights to subscribe for, convert to, or purchase shares of our common stock at a price per share below the NAV 
per share, subject to the applicable requirements of the 1940 Act. There is no expiration date on our ability to issue such 
warrants, options, rights or convertible securities based on this stockholder approval. If we raise additional funds by issuing 
more common stock or senior securities convertible into, or exchangeable for, our common stock, the percentage 
ownership of our stockholders at that time would decrease, and they may experience dilution. Moreover, we can offer no 
assurance that we will be able to issue and sell additional equity securities in the future, on favorable terms or at all.
RISKS RELATED TO OUR SECURITIES
Investing in our securities may involve a high degree of risk.
The investments we make in accordance with our investment objective may result in a higher amount of risk than 
alternative investment options and a higher risk of volatility or loss of principal. Our investments in portfolio companies 
involve higher levels of risk, and therefore, an investment in our securities may not be suitable for someone with lower risk 
tolerance.
Shares of closed-end investment companies, including BDCs, may trade at a discount to their NAV.
Shares of closed-end investment companies, including BDCs, may trade at a discount to NAV. This characteristic 
of closed-end investment companies and BDCs is separate and distinct from the risk that our NAV per share may decline. 
We cannot predict whether our common stock will trade at, above or below NAV. In addition, 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. See Risk Factors — Risks 
Related to our Securities — Stockholders may incur dilution if we sell shares of our common stock in one or more offerings 
at prices below the then current NAV per share of our common stock or issue securities to subscribe to, convert to or 
purchase shares of our common stock. for a discussion related to us issuing shares of our common stock below NAV.
The market price of our securities may be volatile and fluctuate significantly.
Fluctuations in the trading prices of our securities may adversely affect the liquidity of the trading market for our 
securities and, if we seek to raise capital through future securities offerings, our ability to raise such capital. The market 
price and liquidity of the market for our securities may be significantly affected by numerous factors, some of which are 
beyond our control and may not be directly related to our operating performance. These factors include:
•
significant volatility in the market price and trading volume of securities of BDCs or other companies in our 
sector, which are not necessarily related to the operating performance of these companies;
•
changes in regulatory policies, accounting pronouncements or tax guidelines;
•
the exclusion of BDC common stock from certain market indices, such as what happened with respect to the 
Russell indices and the Standard and Poor’s indices, could reduce the ability of certain investment funds to 
own our common stock and limit the number of owners of our common stock and otherwise negatively 
impact the market price of our common stock;
•
inability to obtain any exemptive relief that may be required by us in the future from the SEC;
•
loss of our BDC or RIC status or any of the Funds’ status as an SBIC;
•
changes in our earnings or variations in our operating results;
•
changes in the value of our portfolio of investments;
•
any shortfall in our investment income or net investment income or any increase in losses from levels 
expected by investors or securities analysts;
Table of contents

•
loss of a major funding source;
•
fluctuations in interest rates;
•
the operating performance of companies comparable to us;
•
departure of our key personnel;
•
proposed, or completed, offerings of our securities, including classes other than our common stock;
•
global or national credit market changes; and
•
general economic trends and other external factors.
We may not be able to pay distributions to our stockholders, our distributions may not grow over time, and a portion of 
distributions paid to our stockholders may be a return of capital.
We intend to pay distributions to our stockholders out of assets legally available for distribution. We cannot assure 
you that we will achieve investment results that will allow us to pay a specified level of cash distributions, previously 
projected distributions for future periods, or year-to-year increases in cash distributions. Our ability to pay distributions 
might be adversely affected by, among other things, the impact of one or more of the risk factors described herein. In 
addition, the inability to satisfy the asset coverage test applicable to us as a BDC could limit our ability to pay distributions. 
All distributions will be paid at the discretion of our Board of Directors and will depend on our earnings, our financial 
condition, maintenance of our RIC status, compliance with applicable BDC regulations, compliance with our debt 
covenants and such other factors as our Board of Directors may deem relevant from time to time. We cannot assure you 
that we will pay distributions to our stockholders in the future.
When we make distributions, we will be required to determine the extent to which such distributions are paid out 
of current or accumulated taxable earnings, recognized capital gains or capital. To the extent there is a return of capital, 
investors will be required to reduce their basis in our stock for U.S. federal income tax purposes, which may result in 
higher tax liability when the shares are sold, even if they have not increased in value or have lost value. In addition, any 
return of capital will be net of any sales load and offering expenses associated with sales of shares of our common stock. In 
the future, our distributions may include a return of capital.
Stockholders may incur dilution if we sell shares of our common stock in one or more offerings at prices below the then 
current NAV per share of our common stock or issue securities to subscribe to, convert to or purchase shares of our 
common stock.
The 1940 Act prohibits us from selling shares of our common stock at a price below the current NAV per share of 
such stock, with certain exceptions. One such exception is prior stockholder approval of issuances below NAV provided 
that 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 2024 Annual Meeting of Stockholders, 
and have not sought such authorization since 2012, because our common stock price per share had been trading 
significantly above the NAV per share of our common stock since 2011. We may, however, seek such authorization at 
future annual or special meetings of stockholders. Our stockholders have previously approved a proposal to authorize us to 
issue securities to subscribe to, convert to, or purchase shares of our common stock in one or more offerings. Any decision 
to sell shares of our common stock below the then current NAV per share of our common stock or securities to subscribe 
to, convert to, or purchase shares of our common stock would be subject to the determination by our Board of Directors 
that such issuance is in our and our stockholders’ best interests.
If we were to sell shares of our common stock below NAV per share, such sales would result in an immediate 
dilution to the NAV per share. This dilution would occur as a result of the sale of shares at a price below the then current 
NAV per share of our common stock and a proportionately greater decrease in a stockholder’s interest in our earnings and 
assets and voting interest in us than the increase in our assets resulting from such issuance. In addition, if we issue 
securities to subscribe to, convert to or purchase shares of common stock, the exercise or conversion of such securities 
would increase the number of outstanding shares of our common stock. Any such exercise would be dilutive on the voting 
power of existing stockholders and could be dilutive with regard to dividends and our NAV, and other economic aspects of 
the common stock.
Table of contents
38

Because the number of shares of common stock that could be so issued and the timing of any issuance is not 
currently known, the actual dilutive effect cannot be predicted; however, the example below illustrates the effect of dilution 
to existing stockholders resulting from the sale of common stock at prices below the NAV of such shares.
Illustration: Example of Dilutive Effect of the Issuance of Shares Below NAV. Assume that Company XYZ has 
1,000,000 total shares outstanding, $15,000,000 in total assets and $5,000,000 in total liabilities. The NAV per share of the 
common stock of Company XYZ is $10.00. The following table illustrates the reduction to NAV and the dilution 
experienced by Stockholder A following the sale of 40,000 shares of the common stock of Company XYZ at $9.50 per 
share, a price below its NAV per share.

Provisions of the Maryland General Corporation Law and our articles of incorporation and bylaws could deter takeover 
attempts and have an adverse impact on the price of our common stock.
The Maryland General Corporation Law and our articles of incorporation and bylaws contain provisions that may 
have the effect of discouraging, delaying or making difficult a change in control of our company or the removal of our 
incumbent directors. The existence of these provisions, among others, may have a negative impact on the price of our 
common stock and may discourage third-party bids for ownership of our company. These provisions may prevent any 
premiums being offered to you for our common stock.
We may in the future determine to issue preferred stock, which could adversely affect the market value of our common 
stock.
The issuance of shares of preferred stock with dividend or conversion rights, liquidation preferences or other 
economic terms favorable to the holders of preferred stock could adversely affect the market price for our common stock 
by making an investment in the common stock less attractive. In addition, the dividends on any preferred stock we issue 
must be cumulative. Payment of dividends and repayment of the liquidation preference of preferred stock must take 
preference over any dividends or other payments to our common stockholders, and holders of preferred stock are not 
subject to any of our expenses or losses and are not entitled to participate in any income or appreciation in excess of their 
stated preference (other than convertible preferred stock that converts into common stock). In addition, under the 1940 Act, 
preferred stock constitutes a “senior security” for purposes of the asset coverage test.
RISKS RELATED TO OUR SBIC FUNDS
We, through the Funds, issue debt securities guaranteed by the SBA and sold in the capital markets. As a result of its 
guarantee of the debt securities, the SBA has fixed dollar claims on the assets of the Funds that are superior to the 
claims of our securities holders.
We, through the Funds, have outstanding SBIC debentures guaranteed by the SBA. The debentures guaranteed by 
the SBA have a maturity of ten years from the date of issuance and require semiannual payments of interest. We will need 
to generate sufficient cash flow to make required interest payments on the debentures. If we are unable to meet the 
financial obligations under the debentures, the SBA, as a creditor, will have a superior claim to the assets of the Funds over 
our securities holders in the event we liquidate or the SBA exercises its remedies under such debentures as the result of a 
default by us.
Table of contents
39

The Funds are licensed by the SBA, and therefore subject to SBIC regulations.
The Funds, our wholly-owned subsidiaries, are licensed to act as SBICs and are regulated by the SBA. The SBA 
also places certain limitations on the financing terms of investments by SBICs in portfolio companies and prohibits SBICs 
from providing funds for certain purposes or to businesses in a few prohibited industries. Compliance with SBA 
requirements may cause the Funds to forego attractive investment opportunities that are not permitted under SBIC 
regulations.
Further, the SBIC regulations require, among other things, that a licensed SBIC be periodically examined by the 
SBA and audited by an independent auditor, in each case to determine the SBIC’s compliance with the relevant SBIC 
regulations. The SBA prohibits, without prior SBA approval, a “change of control” of an SBIC or transfers that would 
result in any person (or a group of persons acting in concert) owning 10% or more of a class of capital stock of a licensed 
SBIC. If the Funds fail to comply with applicable SBIC regulations, the SBA could, depending on the severity of the 
violation, limit or prohibit their use of SBIC debentures, declare outstanding SBIC debentures immediately due and 
payable, and/or limit them from making new investments. In addition, the SBA can revoke or suspend a license for willful 
or repeated violation of, or willful or repeated failure to observe, any provision of the Small Business Investment Act of 
1958 or any rule or regulation promulgated thereunder. Such actions by the SBA would, in turn, negatively affect us.
Each of the Funds, as an SBIC, may be unable to make distributions to us that will enable us to meet or maintain RIC 
status, which could result in the imposition of an entity-level tax.
In order for us to continue to qualify for RIC tax treatment and to minimize corporate-level U.S. federal taxes, we 
will be required to distribute substantially all of our net ordinary taxable income and net capital gain income, including 
taxable income from certain of our subsidiaries, which includes the income from the Funds. We will be partially dependent 
on the Funds for cash distributions to enable us to meet the RIC distribution requirements. The Funds may be limited by 
SBIC regulations from making certain distributions to us that may be necessary to enable us to maintain our status as a 
RIC. We may have to request a waiver of the SBA’s restrictions for the Funds to make certain distributions to maintain our 
eligibility for RIC status. We cannot assure you that the SBA will grant such waiver and if the Funds are unable to obtain a 
waiver, compliance with the SBIC regulations may result in loss of RIC tax treatment and a consequent imposition of an 
entity-level tax on us.
FEDERAL INCOME TAX RISKS
We will be subject to corporate-level U.S. federal income tax if we are unable to qualify as a RIC under Subchapter M 
of the Code.
To maintain RIC tax treatment under the Code, we must meet the following annual distribution, income source 
and asset diversification requirements:
•
The Annual Distribution Requirement for a RIC will be satisfied if we distribute to our stockholders on an 
annual basis at least 90% of our net ordinary taxable income and realized net short-term capital gains in 
excess of realized net long-term capital losses, if any. Depending on the level of taxable income earned in a 
tax year, we may choose to carry forward taxable income in excess of current year distributions into the next 
tax year and pay a 4% U.S. federal excise tax on such income. Any such carryover taxable income must be 
distributed through a dividend declared prior to the later of (i) the filing of the final tax return related to the 
year which generated such taxable income or (ii) the fifteenth day of the ninth month following the close of 
the year in which such taxable income was generated. For more information regarding tax treatment, see 
Business — Regulation — Taxation as a Regulated Investment Company. Because we use debt financing, we 
are subject to certain asset coverage ratio requirements under the 1940 Act and are (and may in the future 
become) subject to certain financial covenants under loan and credit agreements that could, under certain 
circumstances, restrict us from making distributions necessary to satisfy the distribution requirement. In 
addition, because we receive non-cash sources of income such as PIK interest which involves us recognizing 
taxable income without receiving the cash representing such income, we may have difficulty meeting the 
distribution requirement. If we are unable to obtain cash from other sources, we could fail to qualify for RIC 
tax treatment and thus become subject to corporate-level U.S. federal income tax.
•
The source-of-income requirement will be satisfied if we obtain at least 90% of our gross income for each 
year from dividends, interest, gains from the sale of stock or securities or similar sources.
Table of contents
40

•
The asset diversification requirement will be satisfied if we meet certain asset diversification requirements at 
the end of each quarter of our taxable year. To satisfy this requirement, at least 50% of the value of our assets 
must consist of cash, cash equivalents, U.S. government securities, securities of other RICs, and other 
acceptable securities; and no more than 25% of the value of our assets can be invested in the securities, other 
than U.S. government securities or securities of other RICs, (i) of one issuer, (ii) of two or more issuers that 
are controlled, as determined under applicable Code rules, by us and that are engaged in the same or similar 
or related trades or businesses or (iii) of certain “qualified publicly traded partnerships.”
Failure to meet these requirements may result in our having to dispose of certain investments quickly in order to 
prevent the loss of RIC status. Because most of our investments are in privately held companies, and therefore illiquid, any 
such dispositions could be made at disadvantageous prices and could result in substantial losses. Moreover, if we fail to 
maintain RIC tax treatment for any reason and are subject to corporate income tax, the resulting corporate taxes could 
substantially reduce our net assets, the amount of income available for distribution and the amount of our distributions.
We may have difficulty paying the distributions required to maintain RIC tax treatment under the Code if we recognize 
income before or without receiving cash representing such income.
We will include in income certain amounts that we have not yet received in cash, such as: (i) amortization of 
original issue discount, which may arise if we receive warrants in connection with the origination of a loan such that 
ascribing a value to the warrants creates original issue discount in the debt instrument, if we invest in a debt investment at a 
discount to the par value of the debt security or possibly in other circumstances; (ii) contractual payment-in-kind, or PIK, 
interest, which represents contractual interest added to the loan balance and due at the end of the loan term; (iii) contractual 
preferred dividends, which represents contractual dividends added to the preferred stock and due at the end of the preferred 
stock term, subject to adequate profitability at the portfolio company; or (iv) amortization of market discount, which is 
associated with loans purchased in the secondary market at a discount to par value. Such amortization of original issue 
discounts, increases in loan balances as a result of contractual PIK arrangements, cumulative preferred dividends, or 
amortization of market discount will be included in income before we receive the corresponding cash payments. We also 
may be required to include in income certain other amounts before we receive such amounts in cash. Investments 
structured with these features may represent a higher level of credit risk compared to investments generating income which 
must be paid in cash on a current basis. 
Since, in certain cases, we may recognize taxable income before or without receiving cash representing such 
income, we may have difficulty meeting the Annual Distribution Requirement necessary to maintain RIC tax treatment 
under the Code. Accordingly, we may have to sell some of our investments at times and/or at prices we would not consider 
advantageous, raise additional debt or equity capital or forgo new investment opportunities for this purpose. If we are not 
able to obtain cash from other sources, we may fail to qualify for RIC tax treatment and thus become subject to corporate-
level U.S. federal income tax. For additional discussion regarding the tax implications of a RIC, please see Item 1. Business 
— Regulation — Taxation as a Regulated Investment Company.
We may in the future choose to pay dividends in our own stock, in which case you may be required to pay tax in excess 
of the cash you receive.
We may distribute taxable dividends that are payable in part in our stock. Under certain applicable provisions of 
the Code and the Treasury regulations, distributions payable by us in cash or in shares of stock (at the stockholders’ 
election) would satisfy the Annual Distribution Requirement. The Internal Revenue Service has issued guidance providing 
that a dividend payable in stock or in cash at the election of the stockholders will be treated as a taxable dividend eligible 
for the dividends paid deduction provided at least 20% of the total distribution is payable in cash and certain other 
requirements are satisfied. According to this guidance, if too many stockholders elect to receive their distributions in cash, 
each such stockholder would receive a pro rata share of the total cash to be distributed and would receive the remainder of 
their distribution in shares of stock. Taxable stockholders receiving such dividends will be required to include the full 
amount of the dividend as ordinary income (or as long-term capital gain to the extent such dividend is properly reported as 
a capital gain dividend) to the extent of our current and accumulated earnings and profits for U.S. federal income tax 
purposes. As a result, a U.S. stockholder may be required to pay tax with respect to such dividends in excess of any cash 
received. If a U.S. stockholder sells the stock it receives as a dividend in order to pay this tax, the sales proceeds may be 
less than the amount included in income with respect to the dividend, depending on the market price of our stock at the 
time of the sale. Furthermore, with respect to non-U.S. stockholders, we may be required to withhold U.S. tax with respect 
to such dividends, including in respect of all or a portion of such dividend that is payable in stock. In addition, if a 
significant number of our stockholders determine to sell shares of our stock in order to pay taxes owed on dividends, it may 
put downward pressure on the trading price of our stock.
Table of contents
41

Stockholders may have current tax liability on dividends they elect to reinvest in our common stock but would not 
receive cash from such dividends to pay such tax liability.
If stockholders participate in our dividend reinvestment plan, they will be deemed to have received, and for 
federal income tax purposes will be taxed on, the amount reinvested in our common stock to the extent the amount 
reinvested was not a tax-free return of capital. As a result, unless a stockholder is a tax-exempt entity, it may have to use 
funds from other sources to pay its tax liability on the value of the dividend that they have elected to have reinvested in our 
common stock.
Legislative or regulatory tax changes could adversely affect our stockholders.
At any time, the federal income tax laws governing RICs or the administrative interpretations of those laws or 
regulations may be amended. Any new laws, regulations or interpretations may take effect retroactively and could 
adversely affect the taxation of us or our stockholders. Therefore, changes in tax laws, regulations or administrative 
interpretations or any amendments thereto could diminish the value of an investment in our shares or the value or the resale 
potential of our investments. If we do not comply with applicable laws and regulations, we could lose any licenses that we 
then hold for the conduct of our business and may be subject to civil fines and criminal penalties.
GENERAL RISK FACTORS
Events outside of our control, including public health crises, supply chain disruptions and inflation, could negatively 
affect our portfolio companies and the results of our operations.
Periods of market volatility could occur in response to pandemics or other events outside of our control. We and 
the portfolio companies in which we invest in could be affected by force majeure events (i.e., events beyond the control of 
the party claiming that the event has occurred, such as acts of God, fire, flood, earthquakes, outbreaks of an infectious 
disease, pandemic or any other serious public health concern, war, terrorism, labor strikes, major plant breakdowns, 
pipeline or electricity line ruptures, failure of technology, defective design and construction, accidents, demographic 
changes, government macroeconomic policies, social instability, etc.). Some force majeure events could adversely affect 
the ability of a party (including us, a portfolio company or a counterparty to us) to perform its obligations until it is able to 
remedy the force majeure event. In addition, force majeure events, such as the cessation of the operation of equipment for 
repair or upgrade, could similarly lead to the unavailability of essential equipment and technologies. These risks could, 
among other effects, adversely impact the cash flows available from a portfolio company, cause personal injury or loss of 
life, including to an officer, director or a member of our investment team, damage property, or instigate disruptions of 
service. In addition, the cost to a portfolio company or us of repairing or replacing damaged assets resulting from such 
force majeure event could be considerable. 
It will not be possible to insure against all such events, and insurance proceeds received, if any, could be 
inadequate to completely or even partially cover any loss of revenues or investments, any increases in operating and 
maintenance expenses, or any replacements or rehabilitation of property. Certain events causing catastrophic loss could be 
either uninsurable, or insurable at such high rates as to adversely impact us or portfolio companies, as applicable. Force 
majeure events that are incapable of or are too costly to cure could have permanent adverse effects. Certain force majeure 
events (such as war or an outbreak of an infectious disease) could have a broader negative impact on the world economy 
and international business activity generally, or in any of the countries in which we invest or our portfolio companies 
operate specifically. Such force majeure events could result in or coincide with: increased volatility in the global securities, 
derivatives and currency markets; a decrease in the reliability of market prices and difficulty in valuing assets; greater 
fluctuations in currency exchange rates; increased risk of default (by both government and private issuers); further social, 
economic, and political instability; nationalization of private enterprise; greater governmental involvement in the economy 
or in social factors that impact the economy; less governmental regulation and supervision of the securities markets and 
market participants and decreased monitoring of the markets by governments or self-regulatory organizations and reduced 
enforcement of regulations; limited, or limitations on, the activities of investors in such markets; controls or restrictions on 
foreign investment, capital controls and limitations on repatriation of invested capital; inability to purchase and sell 
investments or otherwise settle security or derivative transactions (i.e., a market freeze); unavailability of currency hedging 
techniques; substantial, and in some periods extremely high, rates of inflation, which can last many years and have 
substantial negative effects on credit and securities markets as well as the economy as a whole; recessions; and difficulties 
in obtaining and/or enforcing legal judgments.

Market conditions may materially and adversely affect debt and equity capital markets in the United States and abroad, 
which may have a negative impact on our business and operations.
The success of our activities is affected by general economic and market conditions, including, among others, 
interest rates, availability of credit, inflation rates, economic uncertainty, changes in laws, and trade barriers. These factors 
could affect the level and volatility of securities prices and the liquidity of our investments. Volatility or illiquidity could 
impair our profitability or result in losses. These factors also could adversely affect the availability or cost of our leverage, 
which would result in lower returns.
Disruptions in the capital markets could increase the spread between the yields realized on risk-free and higher 
risk securities, resulting in illiquidity in parts of the capital markets. Such disruptions could adversely affect our business, 
financial condition, results of operations and cash flows, and future market disruptions and/or illiquidity could negatively 
impact us. These unfavorable economic conditions could increase our funding costs and limit our access to the capital 
markets, and could result in a decision by lenders not to extend credit to us in the future. These events could limit our 
investments, our ability to grow and could negatively impact our operating results and the fair values of our debt and equity 
investments.
Uncertainty about presidential administration initiatives could negatively impact our business, financial condition and 
results of operations.
There is significant uncertainty with respect to legislation, regulation and government policy at the federal level, 
as well as the state and local levels. Recent events, including the 2024 U.S. presidential election, have created a climate of 
heightened uncertainty and introduced new and difficult-to-quantify macroeconomic and political risks with potentially far-
reaching implications. The presidential administration’s changes to U.S. policy may impact, among other things, the U.S. 
and global economy, international trade and relations, unemployment, immigration, taxes, healthcare, the U.S. regulatory 
environment, inflation and other areas. Although we cannot predict the impact, if any, of these changes to our business, 
they could adversely affect our business, financial condition, operating results and cash flows. Until we know what policy 
changes are made and how those changes impact our business and the business of our competitors over the long term, we 
will not know if, overall, we will benefit from them or be negatively affected by them.
Failure to comply with applicable laws or regulations and changes in laws or regulations governing our operations may 
adversely affect our business or cause us to alter our business strategy.
We, the Funds, and our portfolio companies are subject to applicable local, state and federal laws and regulations. 
Failure to comply with any applicable local, state or federal law or regulation could negatively impact our reputation and 
our business results. New legislation may also be enacted or new interpretations, rulings or regulations could be adopted, 
including those governing the types of investments we are permitted to make, any of which could harm us and our 
stockholders, potentially with retroactive effect. Additionally, any changes to the laws and regulations governing our 
operations relating to permitted investments may cause us to alter our investment strategy in order to avail ourselves of new 
or different opportunities. Such changes could result in material differences to the strategies and plans set forth herein and 
may result in our investment focus shifting from the areas of expertise of our investment team to other types of investments 
in which our investment team may have less expertise or little or no experience. Thus, any such changes, if they occur, 
could have a material adverse effect on our results of operations and the value of your investment.
We may experience fluctuations in our operating results.
We could experience fluctuations in our operating results due to a number of factors, including our ability or 
inability to make investments in companies that meet our investment criteria, the interest rate payable on the debt securities 
we acquire, the level of portfolio dividend and fee income, the level of our expenses, variations in and the timing of the 
recognition of realized and unrealized gains or losses, the degree to which we encounter competition in our markets and 
general economic conditions. As a result of these factors, operating results for any period should not be relied upon as 
being indicative of performance in future periods.
Technological innovations and industry disruptions may negatively impact us.
Technological innovations have disrupted traditional approaches in multiple industries and can permit younger 
companies to achieve success and in the process disrupt markets and market practices. We can provide no assurance that 
new businesses and approaches will not be created that would compete with us and/or our portfolio companies or alter the 
market practices in which we have been designed to function within and on which we depend on for our investment return. 
New approaches could damage our investments, disrupt the market in which we operate and subject us to increased 
competition, which could materially and adversely affect our business, financial condition and results of investments.

We are highly dependent on information systems and systems failures could significantly disrupt our business, which 
may, in turn, negatively affect the market price of our common stock and our ability to pay dividends.
Our business is highly dependent on our and third parties’ communications and information systems. Any failure 
or interruption of those systems, including as a result of the termination of an agreement with any third-party service 
providers, could cause delays or other problems in our activities. Our financial, accounting, data processing, backup or 
other operating systems and facilities may fail to operate properly or become disabled or damaged as a result of a number 
of factors including events that are wholly or partially beyond our control and adversely affect our business. There could 
be:
•
sudden electrical or telecommunications outages;
•
natural disasters such as earthquakes, tornadoes and hurricanes;
•
disease pandemics;
•
events arising from local or larger scale political or social matters, including terrorist acts; and
•
cyber attacks, including software viruses, ransomware, malware and phishing and vishing schemes.
The failure in cybersecurity systems, as well as the occurrence of events unanticipated in our disaster recovery systems 
and management continuity planning could impair our ability to conduct business effectively.
The occurrence of a disaster such as a cyber-attack, a natural catastrophe, an industrial accident, a terrorist attack 
or war, events unanticipated in our disaster recovery systems, or a support failure from external providers, could have an 
adverse effect on our ability to conduct business and on our results of operations and financial condition, particularly if 
those events affect our computer-based data processing, transmission, storage, and retrieval systems or destroy data. If a 
significant number of our managers were unavailable in the event of a disaster, our ability to effectively conduct our 
business could be severely compromised.
We depend heavily upon computer systems to perform necessary business functions. Despite our implementation 
of a variety of security measures, our computer systems could be subject to cyber-attacks and unauthorized access, such as 
physical and electronic break-ins or unauthorized tampering. Like other companies, we may experience threats to our data 
and systems, including malware and computer virus attacks, unauthorized access, system failures and disruptions. If one or 
more of these events occurs, it could potentially jeopardize the confidential, proprietary and other information processed 
and stored in, and transmitted through, our computer systems and networks, or otherwise cause interruptions or 
malfunctions in our operations, which could result in damage to our reputation, financial losses, litigation, increased costs, 
regulatory penalties and/or customer dissatisfaction or loss.
Third parties with which we do business (including, but not limited to, service providers, such as accountants, 
custodians, transfer agents and administrators, and the issuers of securities in which we invest) may also be sources or 
targets of cybersecurity or other technological risks. While we engage in actions to reduce our exposure resulting from 
outsourcing, we cannot control the cybersecurity plans and systems put in place by these third parties and ongoing threats 
may result in unauthorized access, loss, exposure or destruction of data, or other cybersecurity incidents, with increased 
costs and other consequences, including those described above. Privacy and information security laws and regulation 
changes, and compliance with those changes, may also result in cost increases due to system changes and the development 
of new administrative processes.
We are subject to risks associated with artificial intelligence and machine learning technology.
Artificial intelligence, including machine learning and similar tools and technologies that collect, aggregate, 
analyze or generate data or other materials, or collectively, AI, and its current and potential future applications including in 
the private investment and financial industries, as well as the legal and regulatory frameworks within which AI operates, 
continue to rapidly evolve.
Recent technological advances in AI pose risks to us and our portfolio investments. We and our portfolio 
investments could also be exposed to the risks of AI if third-party service providers or any counterparties, whether or not 
known to us, also use AI in their business activities. We and our portfolio companies may not be in a position to control the 
use of AI technology in third-party products or services.
Table of contents
44

Use of AI could include the input of confidential information in contravention of applicable policies, contractual 
or other obligations or restrictions, resulting in such confidential information becoming part accessible by other third-party 
AI applications and users. While we do not currently use AI to make investment recommendations, the use of AI could also 
exacerbate or create new and unpredictable risks to our business and the business of our portfolio companies, including by 
potentially significantly disrupting the markets in which we and our portfolio companies operate or subjecting us and our 
portfolio companies to increased competition and regulation, which could materially and adversely affect business, 
financial condition or results of operations of us and our portfolio companies. In addition, the use of AI by bad actors could 
heighten the sophistication and effectiveness of cyber and security attacks experienced by us or our portfolio companies.
Independent of its context of use, AI technology is generally highly reliant on the collection and analysis of large 
amounts of data, and it is not possible or practicable to incorporate all relevant data into the model that AI technology 
utilizes to operate. Certain data in such models will inevitably contain a degree of inaccuracy and error—potentially 
materially so—and could otherwise be inadequate or flawed, which would be likely to degrade the effectiveness of AI 
technology. To the extent that we or our portfolio investments are exposed to the risks of AI use, any such inaccuracies or 
errors could have adverse impacts on us or our investments.
AI technology and its applications, including in the private investment and financial sectors, continue to develop 
rapidly, and it is impossible to predict the future risks that may arise from such developments.
Item 1B. Unresolved Staff Comments
None.
Item 1C. Cybersecurity
The Company maintains, and routinely reviews and evaluates its information technology (“IT”) and cybersecurity 
policies, practices and procedures (our “Cybersecurity Program”), which includes processes for assessing, identifying and 
managing material risks from cybersecurity threats. The Cybersecurity Program has various policies and procedures 
including a Cyber Incident Response Plan as part of the Company’s Crisis Management Plan. Our Cybersecurity Program 
is administered by our IT Manager, who is managed on a day-to-day basis by our General Counsel and overseen by our IT 
Steering Committee consisting of our Chief Executive Officer, our Chief Operating Officer and our General Counsel. Our 
General Counsel also serves as the crisis response team leader in connection with any material cybersecurity incident under 
the Cyber Incident Response Plan, with our Chief Operating Officer and our IT Manager also included on the crisis 
response team. We also utilize the services of IT and cybersecurity advisers, consultants and experts in the evaluation and 
periodic testing of our IT and cybersecurity systems, to recommend improvements to our Cybersecurity Program and in 
connection with any cybersecurity incident. Our IT Manager has over 10 years of experience advising on and managing 
risks from cybersecurity threats as well as developing and implementing cybersecurity systems, policies and procedures. 
Our General Counsel has served in his oversight function as General Counsel for over 16 years and previously as our Chief 
Compliance Officer for over 12 years, during which time he has gained expertise in assessing and managing risk applicable 
to the Company. Similarly, each of our Chief Executive Officer and our Chief Operating Officer have served in various 
executive management roles at the Company and, in the case of our Chief Operating Officer, other publicly traded 
organizations, involving extensive oversight and management of risks, including cybersecurity related risks, for over 20 
years.
As part of our overall risk management process, our management engages at least annually in an enterprise risk 
management review and evaluation, during which management reviews the principal risks relating to our business and 
operations. Included in this process is a review and evaluation of our risks relating to our Cybersecurity Program. 
Additionally, as part of our Rule 38a-1 compliance program, we review at least annually the compliance policies and 
procedures of our key service providers, including documentation discussing each service providers’ information security 
and privacy controls. Any failure in our or our key service providers’ cybersecurity systems could have a material impact 
on our operating results. See Item 1A. Risk Factors — General Risk Factors — The failure in cybersecurity systems, as well 
as the occurrence of events unanticipated in our disaster recovery systems and management continuity planning could 
impair our ability to conduct business effectively.
Our Board as a whole has responsibility for the Company’s risk oversight, with reviews of certain areas being 
conducted by the relevant Board committees that report on their deliberations to the full Board. The oversight responsibility 
of the Board and its committees is enabled by management reporting processes that are designed to provide visibility to the 
Board about the identification, assessment and management of critical risks and management’s risk mitigation strategies.
Table of contents
45

Oversight of risks relating to IT and cybersecurity has been delegated by our Board to its Audit Committee. The 
Audit Committee includes members of the Board who, in addition to each being designated as an “audit committee 
financial expert,” possess backgrounds and experience which we believe enable them to provide effective oversight of our 
IT and cybersecurity risks. Our management routinely reports to the Audit Committee on the status of the Company’s 
Cybersecurity Program and material risks from cybersecurity threats at the Audit Committee’s quarterly meetings. Such 
reports generally detail any testing, observations or developments concerning the Cybersecurity Program that occurred 
during the prior quarter. The results of periodic testing related to the Cybersecurity Program are also described in the Chief 
Compliance Officer’s annual report to the Board, provided pursuant to Rule 38a-1 under the 1940 Act. The crisis response 
team leader also collaborates with the Audit Committee chair to ensure that the Board is apprised of any material 
cybersecurity incident.
During the reporting period, the Company has not identified any impacts from cybersecurity threats, including as a 
result of previous cybersecurity incidents, that the Company believes have materially affected, or are reasonably likely to 
materially affect, the Company, including its business strategy, operational results and financial condition.
Item 2. Properties
We do not own any real estate or other physical properties materially important to our operations. Currently, we 
lease office space in Houston, Texas for our corporate headquarters.
Item 3. 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 4. Mine Safety Disclosures
Not applicable.

NAV has not yet been determined for the first quarter of 2025.
(1) NAV is determined as of the last day in the relevant quarter and therefore may not reflect the NAV per share on the 
date of the high and low closing prices. The net asset values shown are based on outstanding shares at the end of each 
period.
(2) Calculated for each quarter as (i) NAV subtracted from the respective high or low share price divided by (ii) NAV.
On February 26, 2025, the last sale price of our common stock on the NYSE was $59.58 per share, and there were 
401 holders of record of our common stock which did not include stockholders for whom shares are held in “nominee” or 
“street name.” The NAV per share of our common stock on December 31, 2024 was $31.65, and the premium of the 
February 26, 2025 closing price of our common stock was 88% to this NAV per share.
Shares of BDCs may trade at a market price that is less than the value of the net assets attributable to those shares. 
The possibility that our shares of common stock will trade at a discount from NAV per share or at premiums that are 
unsustainable over the long term are separate and distinct from the risk that our NAV per share will decrease. It is not 
possible to predict whether our common stock will trade at, above, or below NAV per share. Since our IPO in October 
2007, our shares of common stock have traded at prices both less than and exceeding our NAV per share.
DIVIDEND/DISTRIBUTION POLICY
We currently intend to distribute dividends or make distributions to our stockholders out of assets legally available 
for distribution. Our dividends and other distributions, if any, will be determined by our Board of Directors from time to 
time. Our ability to declare dividends depends on our earnings, our overall financial condition (including our liquidity 
position), maintenance of our RIC status and such other factors as our Board of Directors may deem relevant from time to 
time. When we make distributions, we are required to determine the extent to which such distributions are paid out of 
current or accumulated earnings, recognized capital gains or capital. To the extent there is a return of capital (a distribution 
of the stockholders’ invested capital), investors will be required to reduce their basis in our stock for federal tax purposes. 
In the future, our distributions may include a return of capital.

We have adopted a dividend reinvestment and direct stock purchase plan (the “Plan”). The dividend reinvestment 
feature of the Plan (the “DRIP”) provides for the reinvestment of dividends on behalf of our stockholders, unless a 
stockholder has elected to receive dividends in cash. As a result, if we declare a cash dividend, our 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 our common stock. The share requirements of the DRIP may be satisfied through the issuance of new 
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 our common stock on a valuation date determined for each 
dividend by our 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 by the DRIP plan administrator, before any associated 
brokerage or other costs. Our DRIP is administered by our transfer agent on behalf of our record holders and participating 
brokerage firms. Brokerage firms and other financial intermediaries may decide not to participate in our DRIP but may 
provide a similar dividend reinvestment plan for their clients.
SALES OF UNREGISTERED SECURITIES
During the year ended December 31, 2024, we issued a total of 721,963 shares of our common stock under the 
DRIP. These issuances were not subject to the registration requirements of the Securities Act of 1933, as amended. The 
aggregate value of the shares of our common stock issued under the DRIP during 2024 was $35.7 million.
PURCHASES OF EQUITY SECURITIES
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).

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations
The following discussion should be read in conjunction with our consolidated financial statements and the notes 
thereto included elsewhere in this Annual Report on Form 10-K.
Statements we make in the following discussion which express a belief, expectation or intention, as well as those 
that are not historical fact, are forward-looking statements that are subject to risks, uncertainties and assumptions. Our 
actual results, performance or achievements, or industry results, could differ materially from those we express in the 
following discussion as a result of a variety of factors, including the risks and uncertainties we have referred to under the 
headings “Cautionary Statement Concerning Forward-Looking Statements” and “Risk Factors” in this report.

(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, 11.5% for our Private Loan portfolio and 10.1% 
for our Middle Market 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 and Middle Market portfolios. These calculations exclude certain portfolio companies, including five 
LMM portfolio companies, five Private Loan portfolio companies and two Middle Market 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.

(a) As of December 31, 2023, we had equity ownership in all of our LMM portfolio companies, and the average fully 
diluted equity ownership in those portfolio companies was 40%.
(b) The weighted-average annual effective yields were computed using the effective interest rates for all debt investments 
as of December 31, 2023, 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, 2023. 
The weighted-average annual effective yield on our debt portfolio as of December 31, 2023, including debt 
investments on non-accrual status, was 12.9% for our LMM portfolio, 12.5% for our Private Loan portfolio and 10.8% 
for our Middle Market 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 and Middle Market portfolios. These calculations exclude certain portfolio companies, including two 
LMM portfolio companies and two 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.
For the years ended December 31, 2024 and 2023, we achieved a total return on investments of 17.9% and 16.3%, 
respectively. 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 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 and which comprised 2.5% and 
2.9% of our Investment Portfolio at fair value and cost, respectively. As of December 31, 2023, we had Other Portfolio 
investments in 30 entities, spread across 13 investment managers, collectively totaling $142.0 million in fair value and 
$149.1 million in cost basis and which comprised 3.3% and 4.0% of our Investment Portfolio at fair value and cost, 
respectively.
As previously discussed in Item 1. Business — Overview of Our Business of this Annual Report on Form 10-K, we 
hold an investment in the External Investment Manager, a wholly-owned subsidiary that is treated as a portfolio 
investment. 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. As of December 31, 2023, 
this investment had a fair value of $174.1 million and a cost basis of $29.5 million, which comprised 4.1% and 0.8% 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 Policies to the consolidated financial statements included in Item 8. 
Consolidated Financial Statements and Supplementary Data of this Annual Report on Form 10-K.
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 both December 31, 2024 and 2023, our Investment Portfolio valued at fair value represented 96% of our total assets. 
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. — Summary of Significant Accounting Policies — Valuation of the Investment Portfolio included in Item 8. 
Consolidated Financial Statements and Supplementary Data of this Annual Report on Form 10-K 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 December 31, 2024 and 2023 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. 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.
Table of contents
53

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 Taxes included in Item 8. 
Consolidated Financial Statements and Supplementary Data of this Annual Report on Form 10-K), 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 years ended December 31, 2024, 2023 and 2022 (i) 4.2%, 2.2% and 1.4%, respectively, of 
our total investment income was attributable to PIK interest income not paid currently in cash and (ii) 0.5%, 0.3% and 
0.5%, respectively, of our total investment income was attributable to cumulative dividend income not paid currently in 
cash.

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 
Factors — Risks Related to our Investments contained in this Annual Report on Form 10-K 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, 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 December 31, 2024, investments on non-accrual status comprised 0.9% of our total Investment Portfolio at 
fair value and 3.5% at cost. As of December 31, 2023, investments on non-accrual status comprised 0.6% of our total 
Investment Portfolio at fair value and 2.3% 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.

NM — Net Change % not meaningful
(a) Distributable net investment income is net investment income as determined in accordance with U.S. GAAP, 
excluding the impacts 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.

(a) The increase in interest income was primarily due to (i) higher average levels of income producing Investment 
Portfolio debt investments and (ii) increases in weighted-average interest rates on floating rate Investment Portfolio 
debt investments primarily resulting from increases in market spreads, partially offset by an increase in investments on 
non-accrual status.
(b) The increase in dividend income from Investment Portfolio equity investments was primarily a result of an increase of 
$3.8 million in dividend income from our LMM portfolio companies, partially offset by (i) a decrease of $0.8 million 
in dividend income from our Other Portfolio investments and (ii) a decrease of $0.6 million in dividend income from 
our Private Loan portfolio companies. 
(c) The increase in fee income was primarily related to (i) a $5.7 million increase in fees related to increased investment 
activity and (ii) a $2.6 million increase from the refinancing and prepayment of debt investments.
(d) The increase in total investment income includes a net reduction of $3.4 million in certain income considered less 
consistent or non-recurring, including (i) a $6.2 million decrease in such dividend income and (ii) a $0.4 million 
decrease in accelerated interest income from accelerated prepayment, repricing and other activity related to certain 
Investment Portfolio debt investments, partially offset by a $3.3 million increase in such fee income.
Expenses
Total expenses for the year ended December 31, 2024 were $186.0 million, a 15% increase from $161.4 million in

(a) The increase in cash compensation was primarily attributable to (i) increased base compensation rates and (ii) 
increased headcount to support our growing investment portfolio and asset management activities.
(b) The increase in general and administrative expense was primarily attributable to an increase in business development 
activities, technology costs and professional fees.
Table of contents
57

(c) The increase in interest expense was primarily related to (i) an increased weighted-average interest rate on our debt 
obligations resulting primarily from the issuance of the March 2029 Notes and the June 2027 Notes and the repayment 
at maturity of the May 2024 Notes (each as defined in the Liquidity and Capital Resources section below) and (ii) an 
increase in average borrowings outstanding of unsecured notes used to fund a portion of the growth of our Investment 
Portfolio, partially offset by a decrease in average borrowing outstanding on our floating rate multi-year revolving 
credit facility (the “Corporate Facility”) and special purpose vehicle revolving credit facility (the “SPV Facility” and, 
together with the Corporate Facility, the “Credit Facilities”).
(d) The increase in share-based compensation expense was primarily attributable to an increase in incentive based grants 
related to incentive compensation awards issued in April 2024.
(e) The increase in expenses allocated to the External Investment Manager was primarily related to (i) increased overall 
operating costs at Main Street, (ii) the positive operating results from the assets managed for clients of the External 
Investment Manager and (iii) an increase in assets under management.
Net Investment Income
Net investment income for the year ended December 31, 2024 increased 5% to $355.1 million, or $4.09 per share, 
compared to net investment income of $339.0 million, or $4.14 per share, in 2023. The increase in net investment income 
was principally attributable to the increase in total investment income, partially offset by higher operating expenses, both as 
discussed above. Net investment income per share reflects these changes and the impact of the increase in weighted-
average shares outstanding for the year ended December 31, 2024, primarily due to shares issued through our (i) at-the-
market offering program (the “ATM Program”), (ii) dividend reinvestment plan and (iii) equity incentive plans. The 
decrease in net investment income on a per share basis includes a $0.05 per share decrease in investment income 
considered less consistent or non-recurring in nature.
Distributable Net Investment Income
Distributable net investment income for the year ended December 31, 2024 increased 5% to $375.0 million, or 
$4.32 per share, compared to $356.8 million, or $4.36 per share, in 2023. The increase in distributable net investment 
income was primarily due to the increased level of total investment income, partially offset by higher operating expenses, 
excluding the impact of share-based compensation expense, as discussed above, and deferred compensation expense. The 
decrease in distributable net investment income per share reflects the impact of the increase in weighted-average shares 
outstanding for the year ended December 31, 2024, as discussed above. The decrease in distributable net investment 
income on a per share basis includes a $0.05 per share decrease in investment income considered less consistent or non-
recurring in nature.

Income Tax Provision
The income tax provision for the year ended December 31, 2024 of $30.6 million principally consisted of (i) a 
deferred tax provision of $22.3 million, which is primarily the result of the net activity relating to our portfolio investments 
held in our Taxable Subsidiaries, including changes in loss and interest expense carryforwards, changes in net unrealized 
appreciation/depreciation and other temporary book-tax differences and (ii) a current tax provision of $8.4 million related 
to a $5.9 million provision for excise tax on our estimated undistributed taxable income and a $2.5 million provision for 
current U.S. federal and state income taxes.
The income tax provision for the year ended December 31, 2023 of $22.6 million principally consisted of (i) a 
deferred tax provision of $16.0 million and (ii) a current tax provision of $6.6 million primarily related to a $3.4 million 
provision for current U.S. federal and state income taxes and a $3.2 million provision for excise tax on our estimated 
undistributed taxable income.
Net Increase in Net Assets Resulting from Operations
The net increase in net assets resulting from operations for the year ended December 31, 2024 was $508.1 million, 
or $5.85 per share, compared to $428.4 million, or $5.23 per share, during the year ended December 31, 2023. The tables 
above provide a summary of the reasons for the change in net increase in net assets resulting from operations for the year

LIQUIDITY AND CAPITAL RESOURCES
Cash Flows
For the year ended December 31, 2024, we realized a net increase in cash and cash equivalents of $18.2 million, 
which is the net result of $87.1 million of cash used in our operating activities and $105.3 million of cash provided by our 
financing activities.
The $87.1 million of cash used in our operating activities resulted primarily from cash uses totaling $1.576 billion 
for the funding of new and follow-on portfolio investments, partially offset by (i) cash proceeds totaling $1.157 billion 
from the sales and repayments of debt investments and sales and return of capital from equity investments, (ii) cash flows 
that we generated from the operating profits earned totaling $332.8 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 and (iii) $8.5 million in cash proceeds related to other 
assets and liabilities.
The $105.3 million of cash provided by our financing activities principally consisted of (i) $400.0 million in cash 
proceeds from the issuance of the June 2027 Notes, (ii) $350.0 million in cash proceeds from the issuance of the March 
2029 Notes, (iii) $122.6 million in net cash proceeds from equity offerings from our ATM Program, (iv) $63.8 million in 
proceeds from the issuance of SBIC debentures and (v) $24.0 million in net borrowings from our Credit Facilities, partially 
offset by (i) $450.0 million on the repayment of the May 2024 Notes, (ii) $320.4 million in dividends paid to our 
stockholders, (iii) $63.8 million in repayments of SBIC debentures, (iv) $13.6 million in debt issuance costs and (v) $7.3 
million in purchases of vested stock for employee payroll tax withholdings.
For the year ended December 31, 2023, we realized a net increase in cash and cash equivalents of $10.9 million, 
which is the net result of $285.3 million of cash provided by our operating activities and $274.4 million of cash used in our 
financing activities.
The $285.3 million of cash provided by our operating activities resulted primarily from (i) cash proceeds totaling 
$826.0 million from the sales and repayments of debt investments and sales of and return on capital from equity 
investments and (ii) cash flows that we generated from the operating profits earned totaling $328.4 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, partially offset by cash 
uses totaling $867.0 million for the funding of new and follow-on portfolio company investments.
The $274.4 million of cash used in our financing activities principally consisted of (i) $271.6 million in dividends 
paid to stockholders of our common stock, (ii) $247.0 million in net repayments from our Credit Facilities, (iii) $6.0 
million for purchases of vested restricted stock from employees to satisfy their tax withholding requirements upon the 
vesting of such restricted stock and (iv) $3.5 million in debt issuance costs, partially offset by (i) $203.7 million in net cash 
proceeds from equity offerings from our ATM Program (as described below) and direct stock purchase plan and (ii) $50.0 
million in cash proceeds from the issuance of additional aggregate principal amount of the December 2025 Notes (as 
defined below).
Capital Resources
As of December 31, 2024, we had $78.3 million in cash and cash equivalents and $1.326 billion of unused 
capacity under our Credit Facilities which we maintain to support our investment and operating activities. As of 
December 31, 2024, our NAV totaled $2.798 billion, or $31.65 per share.
As of December 31, 2024, we had $208.0 million outstanding and $902.0 million of undrawn commitments under 
our Corporate Facility, and $176.0 million outstanding and $424.0 million of undrawn commitments under our SPV 
Facility, both of which we estimated 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, as described below.
In June 2024, we entered into an amendment to our Corporate Facility to, among other things: (i) increase the 
revolving commitments from $995.0 million to $1.11 billion, (ii) increase the accordion feature from up to a total of $1.4 
billion to up to a total of $1.665 billion and (iii) extend the revolving period and the final maturity date through June 2028 
and June 2029, respectively, on $1.035 billion of revolving commitments, with the original revolving period and final 
maturity date of August 2026 and August 2027, respectively, on $0.075 billion of revolving commitments remaining the 
same.

In September 2024, we entered into an amendment to our SPV Facility, to among other things: (i) increase the 
total commitments from $430.0 million to $600.0 million, (ii) increase the accordion feature to up to a total of $800.0 
million, (iii) extend the revolving period from November 2025 to September 2027, (iv) extend the final maturity date from 
November 2027 to September 2029 and (v) decrease the interest rate to one-month term SOFR plus an applicable margin 
of (a) 2.35% during the revolving period (from 2.50% plus a 0.10% credit spread adjustment, or 2.60%), (b) 2.475% for the 
first year following the end of the revolving period (from 2.625%) and (c) 2.60% for the second year following the end of 
the revolving period (from 2.75%). 
For further information on our Credit Facilities, including key terms and financial covenants, refer to Note E — 
Debt included in Item 8. Consolidated Financial Statements and Supplementary Data of this Annual Report on Form 10-K.
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 
December 31, 2024 and 2023.
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 December 31, 2024.
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 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. On March 1, 
2024, we repaid $63.8 million of SBIC debentures that had reached maturity, which reduced our total outstanding SBIC 
debentures to $286.2 million. Subsequently, on September 12, 2024, we borrowed an additional $63.8 million of SBIC 
debentures, which increased our total outstanding SBIC debentures to $350.0 million. Under existing SBA-approved 
commitments, we had $350.0 million of outstanding SBIC debentures guaranteed by the SBA as of December 31, 2024 
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 5.6 years as of December 31, 2024. 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 December 2022, we issued $100.0 million in aggregate principal amount of 7.84% Series A unsecured notes 
due December 23, 2025 (the “December 2025 Notes”). In February 2023, we issued an additional $50.0 million in 
aggregate principal amount of the December 2025 Notes bearing interest at a fixed rate of 7.53% per year. The outstanding 
aggregate principal amount of the December 2025 Notes as of December 31, 2024 and 2023 was $150.0 million.
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”).

We maintain the ATM Program with certain selling agents through which we can sell up to 15,000,000 shares of 
our common stock by means of at-the-market offerings from time to time. 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. As of December 31, 2024, sales transactions representing 1,678 shares had not settled and 
thus were not issued and not included in shares issued and outstanding on the Consolidated Balance Sheets but are included 
as outstanding on the Consolidated Statement of Changes in Net Assets, in the weighted-average shares outstanding in the 
Consolidated Statements of Operations and in the shares used to calculate the NAV per share. As of December 31, 2024, 
2,823,949 shares remained available for sale under the ATM Program. During the year ended December 31, 2023, we sold 
5,149,460 shares of our common stock at a weighted-average price of $39.94 per share and raised $205.7 million of gross 
proceeds under the ATM Program. Net proceeds were $203.3 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. 
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 2024 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 addition, as a BDC, we generally are required to meet a coverage ratio, or BDC asset 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). In January 2008, we received an exemptive order 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. 
In May 2022, our stockholders also approved the application of the reduced BDC asset coverage ratio. As a result, the BDC 
asset coverage ratio applicable to us decreased from 200% to 150% effective May 3, 2022. As of December 31, 2024, our 
BDC asset coverage ratio was 256%.
Although we have been able to secure access to additional liquidity, including through the 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 Standards included in Item 8. Consolidated Financial Statements and 
Supplementary Data of this Annual Report on Form 10-K.

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, 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 December 31, 2024, we had a total of $322.2 million in outstanding commitments 
comprised of (i) 83 investments with commitments to fund revolving loans that had not been fully drawn or term loans 
with additional commitments not yet funded and (ii) nine investments with equity capital commitments that had not been 
fully called.
Contractual Obligations
As of December 31, 2024, the future fixed commitments for cash payments in connection with the July 2026 
Notes, the June 2027 Notes, the March 2029 Notes, SBIC debentures, the December 2025 Notes and rent obligations under 
our office lease for each of the next five years and thereafter are as follows.

As of December 31, 2024, we had $208.0 million in borrowings outstanding under our Corporate Facility, $14.1 
million of which is scheduled to mature in August 2027 and $193.9 million of which is scheduled to mature in June 2029, 
refer to Note E — Debt included in Item 8. Consolidated Financial Statements and Supplementary Data of this Annual 
Report on Form 10-K. As of December 31, 2024, we had $176.0 million in borrowings outstanding under our SPV Facility, 
and the SPV Facility is scheduled to mature in September 2029.
Related Party Transactions and Agreements
We have entered into agreements and transactions with the External Investment Manager, MSC Income, the 
Private Loan Fund and the 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 and Note L — Related 
Party Transactions included in Item 8. Consolidated Financial Statements and Supplementary Data of this Annual Report 
on Form 10-K 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 cash compensation and directors’ fees, subject to certain limitations. See Note L — 
Related Party Transactions included in Item 8. Consolidated Financial Statements and Supplementary Data of this Annual 
Report on Form 10-K for additional information regarding the deferred compensation plan.
Recent Developments
In January 2025, MSC Income completed a follow-on public offering of 6,325,000 shares of its common stock 
(including the exercise of the underwriters’ overallotment option) at the public offering price of $15.53 per share (the 
“MSIF Public Offering”). In connection with the MSIF Public Offering, MSC Income’s shares of common stock began 
trading on the New York Stock Exchange under the ticker symbol “MSIF.”
We purchased 289,761 shares of MSC Income common stock in the MSIF Public Offering at the public offering 
price of $15.53. Additionally, following the closing of the MSIF Public Offering, we entered into a share purchase plan to 
purchase up to $20.0 million in the aggregate of shares of MSC Income common stock in the open market for a twelve-
month period beginning in March 2025, at times when the market price per share of MSC Income common stock is trading 
below the most recently reported NAV per share of MSC Income’s common stock by certain pre-determined levels 
(including any updates, corrections or adjustments publicly announced by MSC Income to any previously announced NAV 
per share). The purchases of shares of MSC Income common stock pursuant to the share purchase plan are intended to 
satisfy the conditions of Rule 10b5-1 and Rule 10b-18 under the Exchange Act and will otherwise be subject to applicable 
law, including Regulation M, which may prohibit purchases under certain circumstances. MSC Income also entered into a 
share repurchase plan to purchase up to $65.0 million in the aggregate of its common stock in the open market with terms 
and conditions substantially similar to our share purchase plan for shares of MSC Income common stock, and daily 
purchases under the two plans, if any, are expected to be split pro rata (or as close thereto as reasonably possible) between 
us and MSC Income based on the respective plan sizes. In connection with our potential acquisition in excess of 3% of 
MSC Income’s outstanding shares of common stock as a result of any purchases pursuant to our share purchase plan for 
shares of MSC Income common stock or otherwise, we entered into a Fund of Funds Investment Agreement with MSC 
Income. The Fund of Funds Investment Agreement provides for the acquisition by us of MSC Income’s shares of common 
stock, and MSC Income’s sale of such shares to us, in a manner consistent with the requirements of Rule 12d1-4 under the 
1940 Act.
Additionally, in connection with the listing, the External Investment Manager and MSC Income entered into an 
Amended and Restated Investment Advisory and Administrative Services Agreement to, among other things, (i) reduce the 
annual base management fees payable by MSC Income to 1.5% of its average total assets (including cash and cash 
equivalents), payable in arrears (with additional future contractual reductions based upon changes to MSC Income’s 
investment portfolio composition), (ii) reduce to 17.5% the subordinated incentive fee on pre-incentive fee net investment 
income above a specified investment return hurdle rate payable by MSC Income, subject to a 50% / 50% catch-up feature, 
(iii) reduce to 17.5% and reset the incentive fee on cumulative net realized capital gains payable by MSC Income and (iv) 
establish a cap on the amount of expenses payable by MSC Income relating to certain internal administrative services, 
which varies based on the value of MSC Income’s total assets.
In February 2025, we declared a supplemental dividend of $0.30 per share payable in March 2025. This 
supplemental dividend is in addition to the previously announced regular monthly dividends that we declared of $0.25 per 
share for each of January, February and March 2025, or total regular monthly dividends of $0.75 per share for the first 
quarter of 2025, resulting in total dividends declared for the first quarter of 2025 of $1.05 per share. 
Table of contents
65

In February 2025, we also declared regular monthly dividends of $0.25 per share for each of April, May and June 
of 2025. These regular monthly dividends equal a total of $0.75 per share for the second quarter of 2025, representing a 
4.2% increase from the regular monthly dividends paid in the second quarter of 2024. Including the regular monthly and 
supplemental dividends declared through the second quarter of 2025, we will have paid $44.725 per share in cumulative 
dividends since our October 2007 initial public offering.
Item 7A. 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 Facilities 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 rate indices, including SOFR and Prime rates, to the extent that any debt investments include floating interest rates. 
See Risk Factors — Risks Related to our Business and Structure — We are subject to risks associated with the interest rate 
environment and changes in interest rates will affect our cost of capital, net investment income and the value of our 
investments. and Risk Factors — Risks Related to Leverage — Because we borrow money, the potential for gain or loss on 
amounts invested in us is magnified and may increase the risk of investing in us. included in Item 1A. Risk Factors of this 
Annual Report on Form 10-K for more information regarding risks associated with our debt investments and borrowings 
that utilize SOFR or Prime 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 December 31, 2024, 68% of our debt Investment 
Portfolio (at cost) bore interest at floating rates, 95% of which were subject to contractual minimum interest rates. As of 
December 31, 2024, 82% of our debt obligations bore interest at fixed rates. Our interest expense will be affected by 
changes in the published SOFR rate in connection with our Credit Facilities; however, the interest rates on our outstanding 
July 2026 Notes, June 2027 Notes, March 2029 Notes, SBIC Debentures and December 2025 Notes, which collectively 
comprise the majority of our outstanding debt, are fixed for the life of such debt. As of December 31, 2024, 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 Company expects to operate as a “limited 
derivatives user” under Rule 18f-4 under the 1940 Act. In addition, the investment management and other services 
provided by our External Investment Manager also involve floating rate debt investments and floating rate debt obligations, 
and as a result the incentive fees earned by our External Investment Manager, and the corresponding benefits to our net 
investment income contributions from our External Investment Manager, are subject to change based upon any changes in 
floating benchmark index rates.

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, or 
in the investments and borrowings related to the investment management and other services provided by our External 
Investment Manager, in both cases as of December 31, 2024.

(1) Main Street’s total contribution from the External Investment Manager is based on the performance of assets managed 
by the External Investment Manager (as discussed in Note D — External Investment Manager included in Item 8. 
Consolidated Financial Statements and Supplementary Data of this Annual Report on Form 10-K), and any related 
cost of debt obligations related to such managed assets, which may fluctuate depending on changes in interest rates. 
Although we believe that this analysis is indicative of the impact of interest rate changes to our Net Investment 
Income as of December 31, 2024, the analysis does not take into consideration future changes in the credit market, credit 
quality or other business or economic developments that could affect our Net Investment Income. Accordingly, we can 
offer no assurances that actual results would not differ materially from the analysis above. The hypothetical results assume 
that all SOFR and Prime rate changes would be effective on the first day of the period. However, the contractual SOFR and 
Prime rate reset dates would vary throughout the period. The majority of our investments, and the investments managed by 
our External Investment Manager, are based on contracts which reset quarterly, while our Credit Facilities, and the debt 
obligations related to the assets managed by our External Investment Manager, reset monthly. The hypothetical results 
would also be impacted by the changes in the amount of outstanding debt under our Credit Facilities (with an increase 
(decrease) in the debt outstanding under the Credit Facilities resulting in an (increase) decrease in the hypothetical interest 
expense).

Board of Directors and Stockholders
Main Street Capital Corporation
Opinion on the financial statements
We have audited the accompanying consolidated balance sheets of Main Street Capital Corporation (a Maryland 
corporation) and subsidiaries (the “Company”), including the consolidated schedules of investments, as of December 31, 
2024 and 2023, the related consolidated statements of operations, changes in net assets, and cash flows for each of the three 
years in the period ended December 31, 2024 and the related notes and financial statement schedule included under Item 
15(2) (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial 
statements present fairly, in all material respects, the financial position of the Company as of December 31, 2024 and 2023, 
and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2024, in 
conformity with accounting principles generally accepted in the United States of America. 
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board 
(United States) (“PCAOB”), the Company’s internal control over financial reporting as of December 31, 2024, based on 
criteria established in the 2013 Internal Control—Integrated Framework issued by the Committee of Sponsoring 
Organizations of the Treadway Commission (“COSO”), and our report dated February 28, 2025 expressed an unqualified 
opinion.
Basis for opinion
These consolidated financial statements are the responsibility of the Company’s management. Our responsibility 
is to express an opinion on the Company’s consolidated financial statements based on our audits. We are a public 
accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance 
with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission 
and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan 
and perform the audit to obtain reasonable assurance about whether the financial statements are free of material 
misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material 
misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those 
risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial 
statements. Our procedures included verification by confirmation of securities as of December 31, 2024 and 2023, by 
correspondence with the portfolio companies, agent banks and custodians, or by other appropriate auditing procedures 
where replies were not received. Our audits also included evaluating the accounting principles used and significant 
estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that 
our audits provide a reasonable basis for our opinion.
Critical audit matter
The critical audit matter communicated below is a matter arising from the current period audit of the financial 
statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts 
or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or 
complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial 
statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate 
opinion on the critical audit matter or on the accounts or disclosures to which it relates.
Fair Value of Level 3 Investments
As described further in Note C to the financial statements, the Company’s investments recorded at fair value, 
categorized as Level 3 investments within the fair value hierarchy, totaled $4,932,669 thousand at December 31, 2024. 
Approximately 98% of these investments have no readily available market values and are measured using significant 
unobservable inputs and assumptions, and generally use valuation techniques such as the income and market approach. The 
significant unobservable inputs disclosed by management include, among others, weighted-average cost of capital 
(“WACC”) inputs and market multiples for equity investments, and risk adjusted discount rates, and percentage of 
expected principal recovery for debt investments. Changes in these assumptions could have a significant impact on the 
determination of fair value. As such, we identified fair value of Level 3 investments measured using significant 
unobservable inputs and assumptions as a critical audit matter.
Table of contents
Report of Independent Registered Public Accounting Firm
69

The principal consideration for our determination that the fair value of Level 3 investments measured using 
significant unobservable inputs and assumptions is a critical audit matter is management’s judgement used in identifying 
and evaluating significant unobservable inputs which result in estimation uncertainty for the fair value of Level 3 
investments. Auditing these investments requires a high degree of subjective auditor judgment, including use of valuation 
professionals with specialized skills and knowledge, to evaluate the reasonableness of unobservable inputs and 
assumptions.
Our audit procedures related to the fair value of Level 3 investments measured using significant unobservable 
inputs and assumptions included the following, among others:
•
We tested the design and operating effectiveness of management’s review controls relating to the Level 3 fair 
value measurement of investments. This included identifying and evaluating significant assumptions used in 
the estimation of fair value, such as the relevance, adequacy and appropriateness of these significant 
assumptions and valuation methods used to determine investment fair value as of the reporting date.
•
With the assistance of internal valuation specialists, we tested management’s process for developing Level 3 
investment fair values. For a selection of investments, we assessed the appropriateness of the methods and 
significant assumptions used in developing the estimate. The significant assumptions tested by us included, 
but were not limited to, the following:
•
enterprise values,
•
WACC,
•
discount rates,
•
forecasted cash flows and long-term growth rates,
•
discount for lack of marketability,
•
market multiples,
•
weighting between valuation techniques,
•
risk adjusted discount factor, 
•
market debt yields, or
•
percentage of expected principal recovery

Board of Directors and Stockholders
Main Street Capital Corporation
Opinion on internal control over financial reporting
We have audited the internal control over financial reporting of Main Street Capital Corporation (a Maryland 
corporation) and subsidiaries (the “Company”) as of December 31, 2024, based on criteria established in the 2013 Internal 
Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission 
(“COSO”). In our opinion, the Company maintained, in all material respects, effective internal control over financial 
reporting as of December 31, 2024, based on criteria established in the 2013 Internal Control—Integrated Framework 
issued by COSO.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board 
(United States) (“PCAOB”), the consolidated financial statements of the Company as of and for the year ended 
December 31, 2024, and our report dated February 28, 2025 expressed an unqualified opinion on those financial 
statements.
Basis for opinion
The Company’s management is responsible for maintaining effective internal control over financial reporting and 
for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying 
Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the 
Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the 
PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities 
laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and 
perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was 
maintained in all material respects. Our audit included obtaining an understanding of internal control over financial 
reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness 
of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the 
circumstances. We believe that our audit provides a reasonable basis for our opinion.
Definition and limitations of internal control over financial reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance 
regarding the reliability of financial reporting and the preparation of financial statements for external purposes in 
accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes 
those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly 
reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are 
recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting 
principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of 
management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection 
of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial 
statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect 
misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls 
may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures 
may deteriorate.

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 SOFR+7.00% (Floor 1.50%) per the credit agreement and the 
Consolidated Schedule of Investments above reflects such higher rate.

NOTE A — ORGANIZATION AND BASIS OF PRESENTATION
1.
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 alternatives 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 Composition) and the investment in the External Investment Manager (as 
defined below).
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 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 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”).

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 Private 
Loan portfolio companies, investments in Middle Market portfolio companies, Other Portfolio investments, short-term 
portfolio investments and the investment in the External Investment Manager (see Note C — Fair Value Hierarchy for 
Investments — Portfolio Composition — Investment Portfolio Composition for additional discussion of Main Street’s 
Investment Portfolio). Main Street’s results of operations and cash flows for the years ended December 31, 2024, 2023 and 
2022 and financial position as of December 31, 2024 and 2023, are presented on a consolidated basis. The effects of all 
intercompany transactions between MSCC and its consolidated subsidiaries have been eliminated in consolidation.
Principles of Consolidation
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. Accordingly, as noted above, MSCC’s 
consolidated financial statements include the financial position and operating results for the Funds, the Taxable 
Subsidiaries and the Structured 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 Sheets at fair value, as discussed further in Note B.1. — Summary of Significant 
Accounting Policies — Valuation of the Investment Portfolio, with any adjustments to fair value recognized as “Net 
Unrealized Appreciation (Depreciation)” until the investment is realized, usually upon exit, resulting in any gain or loss 
being recognized as a “Net Realized Gain (Loss),” in both cases on the Consolidated Statements of Operations.
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. For purposes of determining the classification 
of its Investment Portfolio, Main Street has excluded consideration of any voting securities or board appointment rights 
held by third-party investment funds advised by the External Investment Manager.
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 LMM 
companies and debt securities issued by Private Loan companies. Main Street also maintains a legacy portfolio of 
investments in Middle Market companies and a limited portfolio of Other Portfolio investments. Main Street’s portfolio 
may also periodically include short-term portfolio investments that are atypical of Main Street’s LMM and Private Loan 
portfolio investments as they are intended to be a short-term deployment of capital and are more liquid than investments 
within the LMM and Private Loan investment portfolios. 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 Private 
Loan investments may include investments which have no established market or have established markets that are not 
active. Middle Market and short-term portfolio investments generally 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, with such 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”) valuation method for its LMM debt investments. For Private Loan and Middle 
Market 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 Middle Market and short-term portfolio investments in debt securities for which it has 
determined that third-party quotes or other independent prices are available, 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 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, changes in market-based interest rates 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 “Financial Advisory Firm”). The Financial 
Advisory Firm analyzes and provides observations, recommendations and an assurance certification regarding Main 
Street’s determinations of the fair value of its LMM portfolio company investments. The Financial Advisory 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 Financial Advisory 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 the Financial Advisory Firm in arriving at its 
determination of fair value for its investments in a total of 68 and 70 LMM portfolio companies during the years ended 
December 31, 2024 and 2023, respectively, representing 93% and 95% of the total LMM portfolio at fair value as of 
December 31, 2024 and 2023, respectively. Excluding its investments in LMM portfolio companies that, as of 
December 31, 2024 and 2023, 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, 99% of the LMM portfolio at fair value was reviewed and certified by the Financial Advisory Firm 
for both of the years ended December 31, 2024 and 2023.
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 the Financial Advisory Firm. The Financial 
Advisory Firm analyzes and provides observations and recommendations and an assurance certification regarding Main 
Street’s determinations of the fair value of its Private Loan portfolio company investments. The Financial Advisory 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 Financial Advisory 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 the 
Financial Advisory Firm in arriving at its determination of fair value for its investments in a total of 66 and 59 Private Loan 
portfolio companies during the years ended December 31, 2024 and 2023, respectively, representing 85% and 82% of the 
total Private Loan portfolio at fair value as of December 31, 2024 and 2023, respectively. Excluding its investments in 
Private Loan portfolio companies that, as of December 31, 2024 and 2023, 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, 97% and 94% of the Private Loan portfolio at fair value was reviewed and certified by the Financial Advisory Firm 
for the years ended December 31, 2024 and 2023, 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. Main Street generally consults on a limited basis with the Financial Advisory Firm in 
connection with determining the fair value of its Middle Market portfolio investments due to the nature of these 
investments. The vast majority (97% and 98% as of December 31, 2024 and 2023, respectively) of the Middle Market 
portfolio investments (i) are valued using third-party quotes or other independent pricing services or (ii) Main Street has 
consulted with and received an assurance certification from the Financial Advisory Firm within the last twelve months.
For valuation purposes, Main Street’s short-term portfolio investments have historically been comprised of 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. Because any short-term portfolio investments are typically valued using third-party quotes or other 
independent pricing services, Main Street generally does not consult with any financial advisory services firms in 
connection with determining the fair value of its short-term portfolio investments.
For valuation purposes, all of Main Street’s Other Portfolio investments are non-control investments. Main 
Street’s Other Portfolio investments comprised 2.5% and 3.3% of Main Street’s Investment Portfolio at fair value as of 
December 31, 2024 and 2023, respectively. 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, and the valuations for comparable 
publicly traded companies and private transactions involving comparable companies. 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. Main Street consults with and receives an assurance certification from the 
Financial Advisory Firm in arriving at its determination of fair value for its investment in the External Investment Adviser 
on a quarterly basis, including as of December 31, 2024 and 2023.
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, Private Loan and Middle 
Market portfolio companies. This system takes into account both quantitative and qualitative factors of each LMM, Private 
Loan and Middle Market portfolio company.
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. Main Street’s Board of Directors has approved policies and procedures pursuant to Rule 2a-5 (the “Valuation 
Procedures”) and has designated a group of its executive officers to serve as the Board of Directors’ valuation designee. 
Main Street believes its Investment Portfolio as of December 31, 2024 and 2023 approximates fair value as of those dates 
based on the markets in which it 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 
as of 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. 
— Summary of Significant Accounting Policies — Valuation of the Investment Portfolio, the consolidated financial 
statements include investments in the Investment Portfolio whose values have been estimated by Main Street, pursuant to 
valuation policies and procedures approved and overseen 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.
Macroeconomic factors, including pandemics, risk of recession, inflation, supply chain constraints or disruptions, 
geopolitical disruptions and changing market index interest rates, and the related effect on the U.S. and global economies, 
have impacted, and may continue to impact, the businesses and operating results of certain of Main Street’s portfolio 
companies. As a result of these and other current effects of macroeconomic factors, as well as the uncertainty regarding the 
extent and duration of their impact, the valuation of Main Street’s Investment Portfolio has and may continue to experience 
increased volatility.
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. As of 
December 31, 2024 and 2023, the Company had $6.5 million and $15.2 million, respectively, of cash equivalents invested 
in AAA-rated money market funds pending investment in the Company’s primary investment strategies. These highly 
liquid investments are included in the Consolidated Schedule of Investments.
As of December 31, 2024 and 2023, cash balances totaling $67.5 million and $40.1 million, respectively, 
exceeded Federal Deposit Insurance Corporation insurance protection levels, subjecting the Company to risk related to the 
uninsured balance. 
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 when dividends are declared by the portfolio company or at such other time that an 
obligation exists for the portfolio company to make a distribution. 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 its debt obligation, 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 obligation, or if a loan or debt security is sold or written off, 
Main Street removes it from non-accrual status.
As of December 31, 2024, investments on non-accrual status comprised 0.9% of Main Street’s total Investment 
Portfolio at fair value and 3.5% at cost. As of December 31, 2023, investments on non-accrual status comprised 0.6% of 
Main Street’s total Investment Portfolio at fair value and 2.3% at cost.

Main Street holds certain debt and preferred equity instruments in its 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 Taxes 
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 years ended December 31, 
2024, 2023 and 2022 (i) 4.2%, 2.2% and 1.4%, respectively, of Main Street’s total investment income was attributable to 
PIK interest income not paid currently in cash and (ii) 0.5%, 0.3% and 0.5%, 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 generally deferred and accreted into income over the life of the financing.

Deferred Financing Costs
Deferred financing costs include commitment fees and other direct costs related to Main Street’s multi-year 
revolving credit facility (the “Corporate Facility”) and special purpose vehicle revolving credit facility (the “SPV Facility” 
and, together with the Corporate Facility, the “Credit Facilities”) and its unsecured notes, as well as the commitment fees 
and leverage fees (3.4% of the total commitment and draw amounts, as applicable) on the SBIC debentures. See further 
discussion of Main Street’s debt in Note E — Debt. Deferred financing costs in connection with the Credit Facilities are 
capitalized as an asset. Deferred financing costs in connection with all other debt arrangements are a direct deduction from 
the principal amount outstanding.

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 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, it 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 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 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 over the life of the debt investment.
To maintain RIC tax treatment (as discussed in Note B.10. — Summary of Significant Accounting Policies — 
Income Taxes 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 years ended December 31, 2024, 
2023 and 2022, 2.0%, 1.8% and 1.8%, 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 amortization.
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 recognizes all excess tax benefits and tax deficiencies associated with share-based compensation 
(including tax benefits of dividends on share-based payment awards) as income tax expense or benefit in the income 
statement and does not delay recognition of a tax benefit until the tax benefit is realized through a reduction to taxes 
payable. As such, 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.
Deferred Compensation Plan
The Main Street Capital Corporation Deferred Compensation Plan (the “Deferred Compensation Plan”) allows 
directors and certain employees to defer receipt of some or all of their cash compensation or directors’ fees in accordance 
with plan terms. Deferred Compensation Plan participants elect one or more investment options, including phantom Main 
Street stock units, interests in affiliated funds and various mutual funds, where their deferred amounts are notionally 
invested, and Main Street invests the deferred amounts through a trust (except for phantom Main Street stock units), 
pending distribution. 
Compensation deferred under the Deferred Compensation Plan is recognized on the same basis as such 
compensation would have been recognized if not deferred. The appreciation (depreciation) in the fair value of deferred 
compensation plan assets is reflected in Main Street's Consolidated Statements of Operations as unrealized appreciation 
(depreciation), with the recognition of a corresponding and offsetting deferred compensation expense or (benefit), 
respectively. Deferred compensation expense or (benefit) does not result in a net cash impact to Main Street upon 
settlement. Investments in the trust are recognized on the Consolidated Balance Sheets as an asset of Main Street (other 
assets) and as a deferred compensation liability (other liabilities).

Phantom Main Street stock units under the Deferred Compensation Plan are not issued shares of Main Street 
common stock and are not included as outstanding on the Consolidated Statements of Changes in Net Assets until such 
shares are actually distributed to the participant, 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 the deferred fees represented by such phantom stock units are earned over the service period. 
Additional phantom stock units from dividends on phantom stock units are included in the Consolidated Statements of 
Changes in Net Assets as an increase to dividends to stockholders offset by a corresponding increase to additional paid-in 
capital.
10.
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 and Structured Subsidiaries, 
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 twelve 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 equity 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 
corporate income 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 corporate income 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. 
Main Street’s net assets as included on the Consolidated Balance Sheets and Consolidated Statements of Changes in Net 
Assets include an adjustment to classification as a result of permanent book-to-tax differences, which include differences in 
the book and tax treatment of income and expenses.
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.

11.
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.
12.
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.
Main Street’s debt instruments, including all revolving and term debt, are accounted for on a historical cost basis 
as applicable under U.S. GAAP. As also required under U.S. GAAP, Main Street discloses the estimated fair value of its 
debt obligations in Note E — Debt. To estimate the fair value of Main Street’s multiple tranches of unsecured debt 
instruments as disclosed in Note E — Debt, Main Street uses quoted market prices. For the estimated fair value of Main 
Street’s SBIC debentures, Main Street uses the Yield-to-Maturity valuation method based on projections of the discounted 
future free cash flows that the debt security will likely generate, including both the discounted cash flows of the associated 
interest and principal amounts for the debt security. The inputs used to value Main Street’s debt instruments for purposes of 
the fair value estimate disclosures in Note E — Debt are considered to be Level 2 according to the ASC 820 fair value 
hierarchy.
13.
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.
14.
Segments
Main Street operates as a single segment with a principal investment objective to maximize total return from 
generating current income from debt investments and current income and capital appreciation from equity and equity-
related investments. The Company’s Investment Committee and Chief Executive Officer collectively perform the function 
that allocates resources and assesses performance, and thus together, serve as the Company’s chief operating decision 
maker (the “CODM”). Among other metrics, the CODM uses net investment income as a primary GAAP profit or loss 
metric used in making operating decisions, which can be found on the Consolidated Statement of Operations along with 
significant expenses. The measure of segment assets is reported on the Consolidated Balance Sheets as total assets. 
15.
Recently Issued or Adopted Accounting Standards
In November 2022, the FASB issued ASU 2022-06, Reference rate reform (Topic 848) — Deferral of the Sunset 
Date of Topic 848, which deferred the sunset date of Topic 848 from December 31, 2022 to December 31, 2024 after 
which entities will no longer be permitted to apply the relief in Topic 848. The Company utilized the optional expedients 
and exceptions provided by ASU 2020-04 and extended by ASU 2022-06 during the year ended December 31, 2023, the 
effect of which was not material to the consolidated financial statements and the notes thereto. For the current year, the 
Company will no longer utilize the optional expedients provided by ASU 2020-04, as LIBOR is no longer referenced in 
any of its contracts. ASU 2022-06 did not have a material impact on the consolidated financial statements and the notes 
thereto.

In November 2023, the FASB issued ASU 2023-07, Segment Reporting - Improvements to Reportable Segment 
Disclosures. The amendments in this update require incremental disclosures related to a public entity’s reportable 
segments. ASU 2023-07 is effective for years beginning after December 15, 2023 and interim periods in fiscal years 
beginning after December 15, 2024. See Note B.14 - Summary of Significant Accounting Policies - Segments for the 
incremental disclosures.
In December 2023, the FASB issued ASU 2023-09, Improvements to Income Tax Disclosures. The amendments 
in this update require more disaggregated information on income taxes paid. ASU 2023-09 is effective for years beginning 
after December 15, 2024, and early adoption is permitted. The Company is currently assessing the impact of the new 
guidance, but it does not expect ASU 2023-09 to have a material impact on the consolidated financial statements and the 
notes thereto.
From time to time, new accounting pronouncements are issued by the FASB or other standards-setting bodies that 
are adopted by the Company as of the specified effective date. The Company 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 — 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 Consolidated Balance Sheets 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.

 MAIN STREET CAPITAL CORPORATION
Notes to the Consolidated Financial Statements (Continued)
152

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 December 31, 2024 and 2023, 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 
December 31, 2024 and 2023.
As of December 31, 2024 and 2023, Main Street’s Private Loan portfolio investments primarily consisted of 
investments in 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 December 31, 2024 and 2023.
As of December 31, 2024 and 2023, 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 December 31, 2024 
and 2023.
As of December 31, 2024 and 2023, Main Street’s Other Portfolio investments consisted of illiquid securities 
issued by privately held entities 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 December 31, 2024 
and 2023.
As of December 31, 2024 and 2023, Main Street did not hold any short-term portfolio investments.
As of December 31, 2024 and 2023, all money market funds included in cash and cash equivalents were valued 
using Level 1 inputs.
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;
•
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;
Table of contents

•
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, and 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, Private Loan and Middle Market debt securities are 
(i) risk adjusted discount rates used in the Yield-to-Maturity valuation technique (see Note B.1. — Summary of Significant 
Accounting Policies — 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.
The following tables provide a summary of the significant unobservable inputs used to fair value Main Street’s 
Level 3 portfolio investments as of December 31, 2024 and 2023:

Investment Portfolio Composition
Main Street’s principal investment objective is to maximize its portfolio’s total return by generating current 
income from its debt investments and current income and capital appreciation from its equity and equity-related 
investments, including warrants, convertible securities and other rights to acquire equity securities in a portfolio company. 
Main Street seeks to achieve its investment objective primarily through its LMM and Private Loan investment strategies.
Main Street’s LMM investment strategy is focused on investments in secured debt and 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 
$125 million. The LMM debt investments are typically secured by a first priority lien on the assets of the portfolio 
company, can include either fixed or floating interest rates and generally have a term of between five and seven years from 
the original investment date. Main Street typically makes direct equity investments and/or receives nominally priced equity 
warrants in connection with a LMM portfolio company debt investment.
Main Street’s Private Loan investment strategy is focused on investments in secured debt in privately held 
companies that generally have annual revenues between $25 million and $500 million, and its Private Loan investments 
generally range in size from $10 million to $100 million. Main Street’s Private Loan investments primarily consist of debt 
securities that have primarily been originated directly by Main Street or, to a lesser extent, through its 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, Main Street’s Private Loan investments are 
typically made in a company owned by or in the process of being acquired by a private equity fund. Main Street’s 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. Main Street may have the option 
to co-invest with the private equity fund in the equity securities of its Private Loan portfolio companies.
Main Street also maintains a legacy portfolio of investments in Middle Market companies. 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 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.
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 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 realized over a five to ten-year period.
Based upon Main Street’s liquidity and capital structure management activities, Main Street’s Investment 
Portfolio may also periodically include short-term portfolio investments that are atypical of Main Street’s LMM, Private 
Loan and Middle Market portfolio investments in that they are intended to be a short-term deployment of capital. Those 
assets are typically expected to be realized in one year or less. These short-term portfolio investments are not expected to 
be a significant portion of the overall Investment Portfolio.
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 under management for External Parties and may 
earn incentive fees, or a carried interest, based on the performance of the assets 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 MSC Income Fund, Inc. (“MSC Income”) and its other clients. 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 years ended 
December 31, 2024, 2023 and 2022 are net of expenses allocated to the External Investment Manager of $23.1 million, 
$22.1 million and $13.0 million, respectively.

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 years ended 
December 31, 2024, 2023 and 2022, Main Street did not record investment income from any single portfolio company in 
excess of 10% of total investment income.
The following tables provide a summary of Main Street’s investments in the LMM, Private Loan and Middle 
Market portfolios as of December 31, 2024 and 2023 (this information excludes Other Portfolio investments and the 
External Investment Manager, which are discussed further below).

(a) As of December 31, 2024, Main Street had equity ownership in all of its 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 Main Street’s debt portfolio as of December 31, 2024, including debt 
investments on non-accrual status, was 12.3% for its LMM portfolio, 11.5% for its Private Loan portfolio and 10.1% 
for its Middle Market portfolio. The weighted-average annual effective yield is not reflective of what an investor in 
shares of Main Street’s common stock will realize on its investment because it does not reflect changes in the market 
value of Main Street’s stock, Main Street’s utilization of debt capital in its capital structure, 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 
Private Loan and Middle Market portfolios. These calculations exclude certain portfolio companies, including five 
LMM portfolio companies, five Private Loan portfolio companies and two Middle Market 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 and those portfolio companies whose primary 
operations have ceased and only residual value remains.

(a) As of December 31, 2023, Main Street had equity ownership in all of its LMM portfolio companies, and the average 
fully diluted equity ownership in those portfolio companies was 40%.
(b) The weighted-average annual effective yields were computed using the effective interest rates for all debt investments 
as of December 31, 2023, 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, 2023. 
The weighted-average annual effective yield on Main Street’s debt portfolio as of December 31, 2023, including debt 
investments on non-accrual status, was 12.9% for its LMM portfolio, 12.5% for its Private Loan portfolio and 10.8% 
for its Middle Market portfolio. The weighted-average annual effective yield is not reflective of what an investor in 
shares of Main Street’s common stock will realize on its investment because it does not reflect changes in the market 
value of Main Street’s stock, Main Street’s utilization of debt capital in its capital structure, 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 
Private Loan and Middle Market portfolios. These calculations exclude certain portfolio companies, including two 
LMM portfolio companies and two 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.
For the years ended December 31, 2024 and 2023, Main Street achieved a total return on investments of 17.9% 
and 16.3%, respectively. 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. Main Street’s total 
return on investments is not reflective of what an investor in shares of Main Street’s common stock will realize on its 
investment because it does not reflect changes in the market value of Main Street’s stock, Main Street’s utilization of debt 
capital in its capital structure, Main Street’s expenses or any sales load paid by an investor.
As of December 31, 2024, Main Street 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 and which comprised 2.5% and 
2.9% of Main Street’s Investment Portfolio at fair value and cost, respectively. As of December 31, 2023, Main Street had 
Other Portfolio investments in 30 entities, spread across 13 investment managers, collectively totaling $142.0 million in 
fair value and $149.1 million in cost basis and which comprised 3.3% and 4.0% of Main Street’s Investment Portfolio at 
fair value and cost, respectively.
As discussed further in Note A.1. — Organization and Basis of Presentation — Organization, Main Street holds 
an investment in the External Investment Manager, a wholly-owned subsidiary that is treated as a portfolio investment. 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 Main Street’s Investment Portfolio at fair value and cost, respectively. As of December 31, 
2023, this investment had a fair value of $174.1 million and a cost basis of $29.5 million, which comprised 4.1% and 0.8% 
of Main Street’s Investment Portfolio at fair value and cost, respectively.

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.” In evaluating its 
unconsolidated controlled portfolio companies in accordance with Regulation S-X, there are two tests that Main Street 
must utilize to determine if any of Main Street’s Control Investments (as defined in Note A — Organization and Basis of 
Presentation, including those unconsolidated portfolio companies defined as Control Investments in which Main Street 
does not own greater than 50% of the voting securities nor have rights to 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 
investments. The income test is generally measured by dividing the absolute value of the combined sum 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 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 December 31, 2024, 2023 and 2022, 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. — Organization and Basis of Presentation — Organization and Note C — Fair 
Value Hierarchy for Investments — Portfolio Composition — Investment Portfolio Composition, 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.
The External Investment Manager serves as the investment adviser and administrator to 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.
As described more fully in Note L — Related Party Transactions, the External Investment Manager also serves as 
the investment adviser and administrator to MS Private Loan Fund I, LP (the “Private Loan Fund”) and MS Private Loan 
Fund II, LP (the “Private Loan Fund II”), each a private investment fund with a strategy to co-invest with Main Street in 
Private Loan portfolio investments. The External Investment Manager entered into investment management agreements in 
December 2020 with the Private Loan Fund and in September 2023 with the Private Loan Fund II, pursuant to which the 
External Investment Manager provides investment advisory and management services to each fund in exchange for an 
asset-based 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.

Notes to the Consolidated Financial Statements (Continued)

The External Investment Manager provides administrative services for certain External Party clients that, to the 
extent not waived, are reported as administrative services fees. The administrative services fees generally represent expense 
reimbursements for a portion of the compensation, overhead and related expenses for certain professionals directly 
attributable to performing administrative services for clients. These fees are recognized as other revenue in the period in 
which the related services are rendered.
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. — Summary of Significant Accounting Policies — Valuation 
of the Investment Portfolio). 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 Main Street and is not included as a consolidated subsidiary of Main Street in its 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 corporate income 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 
activities and assets under management, depending on the nature of the expense. 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 years ended 
December 31, 2024, 2023 and 2022, the total contribution to Main Street’s net investment income was $34.3 million, $33.4 
million and $22.3 million, respectively.
Summarized financial information from the separate financial statements of the External Investment Manager as 
of December 31, 2024 and 2023 and for the years ended December 31, 2024, 2023 and 2022 is as follows:

Corporate Facility
Main Street maintains the Corporate Facility to provide additional liquidity to support its investment and 
operational activities. In June 2024, Main Street entered into an amendment to the Corporate Facility to, among other 
things: (i) increase the revolving commitments from $995.0 million to $1.11 billion, (ii) increase the accordion feature 
providing Main Street 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 from up to a total of $1.4 billion to up to a total of $1.665 
billion, and (iii) extend the revolving period and the final maturity date through June 2028 and June 2029, respectively, on 
$1.035 billion of revolving commitments, and August 2026 and August 2027, respectively, on $0.075 billion of revolving 
commitments.
As of December 31, 2024, borrowings under the Corporate Facility bore 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 SOFR 
rate plus an applicable credit spread adjustment of 0.10% plus (i) 1.875% (or the applicable Prime rate 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 Prime Rate plus 1.0%) otherwise. Main Street pays unused commitment fees of 0.25% per annum on the unused 
lender commitments under the Corporate Facility. The Corporate 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. In 
connection with the Corporate Facility, MSCC has made customary representations and warranties and is required to 
comply with various covenants, reporting requirements and other customary requirements for similar credit facilities.
As of December 31, 2024, the interest rate for borrowings on the Corporate Facility was 6.5%. The average

commitments from $430.0 million to $600.0 million, (ii) increase the accordion feature providing MSCC Funding with the 
right to request increases in commitments under the facility, subject to the satisfaction of various conditions, from new and 
existing lenders on the same terms and conditions as the existing commitments to up to a total of $800.0 million, (iii) 
extend the revolving period from November 2025 to September 2027, (iv) extend the final maturity date from November 
2027 to September 2029 and (v) decrease the interest rate to one-month term SOFR plus an applicable margin of (a) 2.35% 
during the revolving period (from 2.50% plus a 0.10% credit spread adjustment, or 2.60% in total), (b) 2.475% for the first 
year following the end of the revolving period (from 2.625%) and (c) 2.60% for the second year following the end of the 
revolving period (from 2.75%).
As of December 31, 2024, the SPV Facility included total commitments of $600.0 million from a diversified 
group of six lenders. Advances under the SPV Facility bear interest at a per annum rate equal to the one-month term SOFR 
in effect, plus an applicable margin of 2.35% during the revolving period and 2.475% and 2.60% during the first and 
second years thereafter, respectively. MSCC Funding pays a commitment fee of 0.50% per annum on the unused lender 
commitments up to 35% of the total lender commitments and 0.75% per annum on the unused lender commitments greater 
than 35% of the total lender commitments. The SPV Facility is secured by a collateral loan on the assets of MSCC Funding 
and its subsidiaries. In connection with the SPV Facility, MSCC Funding has made customary representations and 
warranties and is required to comply with various covenants, reporting requirements and other customary requirements for

option at par plus accrued interest to the prepayment date, subject to certain make-whole provisions. The December 2025 
Series A Notes and the December 2025 Series B Notes bear interest at a rate of 7.84% and 7.53% per year, respectively, 
payable semiannually on June 23 and December 23 of each year. In addition, Main Street is obligated to offer to repay the 
December 2025 Notes at par plus accrued and unpaid interest if certain change in control events occur. The December 2025 
Notes will bear interest at an increased rate from the date that (i) the December 2025 Notes receive a below investment 
grade rating by a rating agency if there is one or two rating agencies providing ratings of the December 2025 Notes, or two-
thirds of the rating agencies if there are three rating agencies who are rating the notes (a “Below Investment Grade Event”), 
or (ii) the ratio of the Company’s consolidated secured indebtedness (other than indebtedness of the Funds or any 
Structured Subsidiaries) to the value of its consolidated total assets is greater than 0.35 to 1.00 (a “Secured Debt Ratio 
Event”), to and until the date on which the Below Investment Grade Event and the Secured Debt Ratio Event are no longer 
continuing. The governing agreement for the December 2025 Notes contains customary terms and conditions for senior 
unsecured notes issued in a private placement, as well as customary events of default with customary cure and notice 
periods.
As of December 31, 2024, Main Street was in compliance with all covenants and other requirements of the 
December 2025 Notes.

___________________________
(1) Total expenses are the sum of operating expenses and net income tax provision or benefit. Net income tax provision or 
benefit includes the accrual of net deferred tax provision or benefit relating to the net unrealized appreciation or 
depreciation on portfolio investments held in Taxable Subsidiaries and due to the change in the loss carryforwards, 
which are non-cash in nature and may vary significantly from period to period. Main Street is required to include net 
deferred tax provision or benefit in calculating its total expenses even though these net deferred taxes are not currently 
payable or receivable.
(2) Unless otherwise noted, operating expenses include interest, compensation, general and administrative and share-based 
compensation expenses, net of expenses allocated to the External Investment Manager of $23.1 million, $22.1 million, 
$13.0 million, $10.3 million, $7.4 million, $6.7 million, $6.8 million, $6.4 million, $5.1 million and $4.3 million for 
the years ended December 31, 2024, 2023, 2022, 2021, 2020, 2019, 2018, 2017, 2016 and 2015, respectively.
(3) Total investment return is based on the purchase of stock at the current market price on the first day and a sale at the 
current market price on the last day of each period reported on the table and assumes reinvestment of dividends at 
prices obtained by Main Street’s dividend reinvestment plan during the period. The return does not reflect any sales 
load that may be paid by an investor.
(4) Total return based on change in NAV was calculated using the sum of ending NAV plus dividends to stockholders and 
other non-operating changes during the period, divided by the beginning NAV. Non-operating changes include any 
items that affect NAV other than the net increase in net assets resulting from operations, such as the effects of stock 
offerings, shares issued under the DRIP and equity incentive plans and other miscellaneous items.

regular monthly dividends of $0.245 per share for each month of July through December. The 2024 regular monthly 
dividends, which total $252.3 million, or $2.91 per share, represent a 6.0% per share increase from the regular monthly 
dividends paid totaling $224.3 million, or $2.745 per share, for the year ended December 31, 2023.
During 2024, Main Street also paid supplemental dividends of $0.30 per share in March, June, September and 
December, totaling $104.5 million, or $1.20 per share. During 2023, Main Street paid supplemental dividends of $0.175 
per share in March, $0.225 per share in June, $0.275 per share in September and $0.275 per share in December, totaling 
$78.6 million, or $0.95 per share. 
During 2024, the regular monthly dividends and supplemental dividends paid totaled $356.8 million, or $4.11 per 
share, representing a 11.2% per share increase from the total dividends paid during the year ended December 31, 2023. 
During the year ended December 31, 2023, the regular monthly dividends and supplemental dividends paid totaled $302.9 
million, or $3.695 per share.
For tax purposes, the 2024 dividends were comprised of (i) ordinary income totaling $2.84 per share and (ii) 
qualified dividend income totaling $1.27 per share. As of December 31, 2024, Main Street estimates that it has generated 
undistributed taxable income of $142.6 million, or $1.61 per share, that will be carried forward toward distributions to be 
paid in 2025.
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 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 twelve 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. The tax character of distributions paid for the years ended December 31, 2024, 2023 and 2022 
was as follows:

Notes to the Consolidated Financial Statements (Continued)

The Taxable Subsidiaries primarily hold certain equity 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 MSCC 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 
corporate income 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 for Main Street is generally composed of (i) deferred tax expense, 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. The income tax expense, or benefit, and the related tax assets and 
liabilities generated by the Taxable Subsidiaries, if any, are reflected in Main Street’s Consolidated Statements of 
Operations. Main Street’s provision for income taxes was comprised of the following for the years ended December 31, 
2024, 2023 and 2022:

MSCC operates in a manner to maintain its RIC status and to eliminate corporate-level U.S. federal income tax 
(other than the 4% excise tax) by distributing sufficient investment company taxable income and long-term capital gains. 
As a result, MSCC will have an effective tax rate equal to 0% before the excise tax and income taxes incurred by the 
Taxable Subsidiaries. As such, a reconciliation of the differences between Main Street’s reported income tax expense and 
its tax expense at the federal statutory rate of 21% is not meaningful. 
As of December 31, 2024, the cost of investments for U.S. federal income tax purposes was $4,231.6 million, with 
such investments having an estimated net unrealized appreciation of $701.1 million, composed of gross unrealized 
appreciation of $1,082.8 million and gross unrealized depreciation of $381.7 million.

(112,628)

Total deferred tax liabilities, net
$ 
(86,111) $ 
(63,858) 
The net deferred tax liability as of December 31, 2024 and 2023 was $86.1 million and $63.9 million, 
respectively, with the change 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. 
Management believes that the realization of the deferred tax assets is more likely than not based on expectations as to 
future taxable income and scheduled reversals of temporary differences. Accordingly, Main Street did not record a 
valuation allowance related to its deferred tax assets as of December 31, 2024 and 2023. As of December 31, 2024, for 
U.S. federal income tax purposes, the Taxable Subsidiaries had a net operating loss carryforward from prior years which is 
not subject to expiration and will carryforward indefinitely until utilized. Additionally, the Taxable Subsidiaries have 
interest expense limitation carryforwards which have an indefinite carryforward period. In addition, as of December 31, 
2024, for U.S. federal income tax purposes, MSCC had net capital loss carryforwards totaling $62.0 million available to 
offset future capital gains at the RIC level in any taxable year, to the extent available and permitted by U.S. federal income 
tax law, which are not subject to expiration as long as MSCC maintains its RIC status.
NOTE H — COMMON STOCK
Main Street maintains a program with certain selling agents through which it can sell up to 15,000,000 shares of 
its common stock by means of at-the-market offerings from time to time (the “ATM Program”).
During the year ended December 31, 2024, Main Street sold 2,489,275 shares of its 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. As of December 31, 2024, sales 
transactions representing 1,678 shares had not settled and thus were not issued and not included in shares issued and 
outstanding on the Consolidated Balance Sheets but are included as outstanding on the Consolidated Statement of Changes 
in Net Assets, in the weighted-average shares outstanding in the Consolidated Statements of Operations and in the shares 
used to calculate the NAV per share. As of December 31, 2024, 2,823,949 shares remained available for sale under the 
ATM Program.
During the year ended December 31, 2023, Main Street sold 5,149,460 shares of its common stock at a weighted-
average price of $39.94 per share and raised $205.7 million of gross proceeds under the ATM Program. Net proceeds were 
$203.3 million after commissions to the selling agents on shares sold and offering costs.
During the year ended December 31, 2022, Main Street sold 5,407,382 shares of its common stock at a weighted-
average price of $39.29 per share and raised $212.4 million of gross proceeds under the ATM Program. Net proceeds were 
$209.9 million after commissions to the selling agents on shares sold and offering costs.

During August 2022, Main Street completed a public equity offering of 1,345,500 shares of common stock at a 
public offering price of $42.85 per share, including the underwriters’ full exercise of their option to purchase 175,500 
additional shares, resulting in total net proceeds, including exercise of the underwriters’ option to purchase additional 
shares and after deducting underwriting discounts and estimated offering expenses payable by Main Street, of 
approximately $55.1 million. 
NOTE I — DIVIDEND REINVESTMENT PLAN
The dividend reinvestment feature of Main Street’s dividend reinvestment and direct stock purchase plan (the 
“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.
Summarized DRIP information for the years ended December 31, 2024, 2023 and 2022 is as follows:

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 (“RSAs”), 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 2022 Equity and Incentive Plan (the “Equity and Incentive Plan”). These 
shares generally vest over a three-year or five-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 December 31, 2024.

employee directors and the remaining shares of restricted stock available for issuance pursuant to the Main Street Capital 
Corporation 2022 Non-Employee Director Restricted Stock Plan. These shares are granted upon appointment or election to 
the board and vest on the day immediately preceding the annual meeting of stockholders following the respective grant date 
and are expensed over such service period.

Company does not expect any further capital will be called on its commitment for follow on investments. As a result, 
the Company has excluded those commitments from this table.

Notes to the Consolidated Financial Statements (Continued)

Main Street will fund its unfunded commitments from the same sources it uses to fund its investment 
commitments that are funded at the time they are made (which are typically through existing cash and cash equivalents and 
borrowings under the Credit Facilities). Main Street follows a process to manage its liquidity and ensure that it has 
available capital to fund its unfunded commitments as necessary. The Company had no unrealized appreciation or 
depreciation on the outstanding unfunded commitments as of December 31, 2024.
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 — External Investment Manager, the External Investment Manager is treated as a 
wholly-owned portfolio company of Main Street and is included as part of Main Street’s Investment Portfolio. As of 
December 31, 2024, Main Street had a receivable of $10.2 million due from the External Investment Manager, which 
included (i) $7.8 million related primarily to operating expenses incurred by Main Street 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 — External Investment Manager) and (ii) $2.4 million of dividends declared 
but not paid by the External Investment Manager. MSCC has entered into an agreement with the External Investment 
Manager to share employees in connection with its asset management business generally, and specifically for the External 
Investment Manager’s relationship with MSC Income and its other clients (see further discussion in Note A.1. — 
Organization and Basis of Presentation — Organization and Note D — External Investment Manager).
From time to time, Main Street may make investments in clients of the External Investment Manager in the form 
of debt or equity capital on terms approved by Main Street’s Board of Directors, including each director who is not an 
“interested person,” as such term is defined in Section 2(a)(19) of the 1940 Act.

(1) Unless otherwise noted below, Main Street purchased shares at the price shares were purchased by MSC Income 
stockholders pursuant to MSC Income’s dividend reinvestment plan for its dividend on such date.
(2) MSC Income completed a two-for-one reverse stock split, effective as of December 16, 2024; as such, shares 
purchased and price per share have been adjusted to reflect the Reverse Stock Split on a retrospective basis.
(3) Main Street purchased shares through the modified “Dutch Auction” tender offer commenced by MSC Income and 
Main Street in August 2023 to purchase, severally and not jointly, up to an aggregate of $3.5 million of shares from 
stockholders of MSC Income, subject to the conditions described in the offer to purchase dated August 16, 2023.
Each of Main Street’s purchases of MSC Income common stock was unanimously approved by the Board of 
Directors and MSC Income’s board of directors, including each director who is not an “interested person,” as such term is 
defined in Section 2(a)(19) of the 1940 Act, of each board. As of December 31, 2024, Main Street had not sold any shares 
of MSC Income’s common stock previously purchased and owned 1,085,111 shares of MSC Income’s common stock. In 
addition, certain of Main Street’s officers and employees own shares of MSC Income and therefore have direct pecuniary 
interests in MSC Income.
In December 2020, the External Investment Manager entered into an investment management agreement with the 
Private Loan Fund to provide investment advisory and management services in exchange for an asset-based fee and certain 
incentive fees. The Private Loan Fund is a private investment fund exempt from registration under the 1940 Act that co-
invests with Main Street in Main Street’s Private Loan investment strategy. In connection with the Private Loan Fund’s 
initial closing in December 2020, Main Street committed to contribute up to $10.0 million as a limited partner and is 
entitled to distributions on such interest. In February 2022, Main Street increased its total commitment to the Private Loan 
Fund from $10.0 million to $15.0 million. In addition, certain of Main Street’s officers and employees (and certain of their 
immediate family members) have made capital commitments to the Private Loan Fund as limited partners and therefore 
have direct pecuniary interests in the Private Loan Fund. As of December 31, 2024, Main Street has funded $14.2 million 
of its limited partner commitment and Main Street’s unfunded commitment was $0.8 million. Main Street’s limited partner 
commitment to the Private Loan Fund was unanimously approved by the Board of Directors, including each director who is 
not an “interested person,” as such term is defined in Section 2(a)(19) of the 1940 Act.
Additionally, Main Street provided the Private Loan Fund with a revolving line of credit pursuant to an Unsecured 
Revolving Promissory Note, dated February 5, 2021 and was subsequently amended on November 30, 2021 and on 
December 29, 2021 (as amended, the “PL Fund 2021 Note”), in an aggregate amount equal to the amount of limited partner 
capital commitments to the Private Loan Fund up to $85.0 million. Borrowings under the PL Fund 2021 Note bore interest 
at a fixed rate of 5.00% per annum and matured on February 28, 2022. The PL Fund 2021 Note was unanimously approved 
by Main Street’s Board of Directors, including each director who is not an “interested person,” as such term is defined in 
Section 2(a)(19) of the 1940 Act. In February 2022, the Private Loan Fund fully repaid all borrowings outstanding under 
the PL Fund 2021 Note and the PL Fund 2021 Note was extinguished.
In March 2022, Main Street provided the Private Loan Fund with a revolving line of credit pursuant to a Secured 
Revolving Promissory Note, dated March 17, 2022 (the “PL Fund 2022 Note”), which provides for borrowings up to $10.0 
million. Borrowings under the PL Fund 2022 Note bear interest at a fixed rate of 5.00% per annum and mature on the date 
upon which the Private Loan Fund’s investment period concludes, which is scheduled to occur in March 2026. Available 
borrowings under the PL Fund 2022 Note are subject to a 0.25% non-use fee. The PL Fund 2022 Note was unanimously 
approved by Main Street’s Board of Directors, including each director who is not an “interested person,” as such term is 
defined in Section 2(a)(19) of the 1940 Act. As of December 31, 2024, there were $1.6 million of borrowings outstanding 
under the PL Fund 2022 Note.

In September 2023, the External Investment Manager entered into an investment management agreement with the 
Private Loan Fund II to provide investment advisory and management services in exchange for an asset-based fee and 
certain incentive fees. The Private Loan Fund II is a private investment fund exempt from registration under the 1940 Act 
that co-invests with Main Street in Main Street’s Private Loan investment strategy. In connection with the Private Loan 
Fund II’s initial closing in September 2023, Main Street committed to contribute up to $15.0 million (limited to 20% of 
total commitments) as a limited partner and is entitled to distributions on such interest. In addition, certain of Main Street’s 
officers and employees (and certain of their immediate family members) have made capital commitments to the Private 
Loan Fund II as limited partners and therefore have direct pecuniary interests in the Private Loan Fund II. As of 
December 31, 2024, Main Street has funded $7.4 million of its limited partner commitment and Main Street’s unfunded 
commitment was $5.0 million. Main Street’s limited partner commitment to the Private Loan Fund II was unanimously 
approved by the Board of Directors, including each director who is not an “interested person,” as such term is defined in 
Section 2(a)(19) of the 1940 Act.
In September 2023, Main Street provided the Private Loan Fund II with a revolving line of credit pursuant to a 
Secured Revolving Promissory Note, dated September 5, 2023 (as amended, the “PL Fund II 2023 Note”), which provides 
for borrowings up to $50.0 million. Borrowings under the PL Fund II 2023 Note bear interest at a rate of SOFR plus 3.50% 
per annum, subject to a 2.00% SOFR floor, and mature on September 5, 2025. Available borrowings under the PL Fund II 
2023 Note are subject to a 0.25% non-use fee. The borrowings are collateralized by all assets of the Private Loan Fund II. 
The PL Fund II 2023 Note was unanimously approved by Main Street’s Board of Directors, including each director who is 
not an “interested person,” as such term is defined in Section 2(a)(19) of the 1940 Act. In November 2024, the Private 
Loan Fund II fully repaid all borrowings outstanding under the PL Fund II 2023 Note and the PL Fund II Note was 
extinguished.
In November 2024, Main Street provided the Private Loan Fund II with a revolving line of credit pursuant to a 
Secured Revolving Promissory Note, dated November 22, 2024 (the “PL Fund II 2024 Note”), which provides for 
borrowings up to $10.0 million. Borrowings under the PL Fund II 2024 Note bear interest at a rate of SOFR plus 3.00% per 
annum, subject to a 2.00% SOFR floor, and mature on the date upon which the Private Loan Fund II’s investment period 
concludes, which is scheduled to occur in March 2029. Available borrowings under the PL Fund II 2024 Note are subject 
to a 0.25% non-use fee. The PL Fund II 2024 Note was unanimously approved by Main Street’s Board of Directors, 
including each director who is not an “interested person,” as such term is defined in Section 2(a)(19) of the 1940 Act. As of 
December 31, 2024, there were no borrowings outstanding under the PL Fund II 2024 Note.
As described in Note B.9. — Summary of Significant Accounting Policies — Deferred Compensation Plan, 
participants in the Deferred Compensation Plan elect one or more investment options, including phantom Main Street stock 
units, interests in affiliated funds and various mutual funds, where their deferred amounts are notionally invested pending 
distribution pursuant to participant elections and plan terms. As of December 31, 2024, $26.6 million of compensation, 
plus net unrealized gains and losses and investment income, and minus previous distributions, was deferred under the 
Deferred Compensation Plan. As of December 31, 2024, $11.0 million was deferred into phantom Main Street stock units, 
representing 187,350 shares of Main Street’s common stock. In addition, as of December 31, 2024, the Company had $15.6 
million of funded investments from deferred compensation in trust, including $2.1 million in the Private Loan Fund and 
$4.2 million in the Private Loan Fund II.

NOTE M — SUBSEQUENT EVENTS
Our management has evaluated subsequent events through the date of issuance of the consolidated financial 
statements, and identified the following to report:
In January 2025, MSC Income completed a follow-on public offering of 6,325,000 shares of its common stock 
(including the exercise of the underwriters’ overallotment option) at the public offering price of $15.53 per share (the 
“MSIF Public Offering”). In connection with the MSIF Public Offering, MSC Income’s shares of common stock began 
trading on the New York Stock Exchange under the ticker symbol “MSIF.”
Main Street purchased 289,761 shares of MSC Income common stock in the MSIF Public Offering at the public 
offering price of $15.53. Additionally, following the closing of the MSIF Public Offering, Main Street entered into a share 
purchase plan to purchase up to $20.0 million in the aggregate of shares of MSC Income common stock in the open market 
for a twelve-month period beginning in March 2025, at times when the market price per share of MSC Income common 
stock is trading below the most recently reported NAV per share of MSC Income’s common stock by certain pre-
determined levels (including any updates, corrections or adjustments publicly announced by MSC Income to any 
previously announced NAV per share). The purchases of shares of MSC Income common stock pursuant to the share 
purchase plan are intended to satisfy the conditions of Rule 10b5-1 and Rule 10b-18 under the Exchange Act and will 
otherwise be subject to applicable law, including Regulation M, which may prohibit purchases under certain circumstances. 
MSC Income also entered into a share repurchase plan to purchase up to $65.0 million in the aggregate of its common 
stock in the open market with terms and conditions substantially similar to Main Street’s share purchase plan for shares of 
MSC Income common stock, and daily purchases under the two plans, if any, are expected to be split pro rata (or as close 
thereto as reasonably possible) between Main Street and MSC Income based on the respective plan sizes. In connection 
with Main Street’s potential acquisition in excess of 3% of MSC Income’s outstanding shares of common stock as a result 
of any purchases pursuant to Main Street’s share purchase plan for shares of MSC Income common stock or otherwise, 
Main Street entered into a Fund of Funds Investment Agreement with MSC Income. The Fund of Funds Investment 
Agreement provides for the acquisition by Main Street of MSC Income’s shares of common stock, and MSC Income’s sale 
of such shares to Main Street, in a manner consistent with the requirements of Rule 12d1-4 under the 1940 Act.
Additionally, in connection with the listing, the External Investment Manager and MSC Income entered into an 
Amended and Restated Investment Advisory and Administrative Services Agreement to, among other things, (i) reduce the 
annual base management fees payable by MSC Income to 1.5% of its average total assets (including cash and cash 
equivalents), payable in arrears (with additional future contractual reductions based upon changes to MSC Income’s 
investment portfolio composition), (ii) reduce to 17.5% the subordinated incentive fee on pre-incentive fee net investment 
income above a specified investment return hurdle rate payable by MSC Income, subject to a 50% / 50% catch-up feature, 
(iii) reduce to 17.5% and reset the incentive fee on cumulative net realized capital gains payable by MSC Income and (iv) 
establish a cap on the amount of expenses payable by MSC Income relating to certain internal administrative services, 
which varies based on the value of MSC Income’s total assets.
In February 2025, Main Street declared a supplemental dividend of $0.30 per share payable in March 2025. This 
supplemental dividend is in addition to the previously announced regular monthly dividends that Main Street declared of 
$0.25 per share for each of January, February and March 2025, or total regular monthly dividends of $0.75 per share for the 
first quarter of 2025, resulting in total dividends declared for the first quarter of 2025 of $1.05 per share.
In February 2025, Main Street also declared regular monthly dividends of $0.25 per share for each of April, May 
and June of 2025. These regular monthly dividends equal a total of $0.75 per share for the second quarter of 2025, 
representing a 4.2% increase from the regular monthly dividends paid in the second quarter of 2024. Including the 
regular monthly and supplemental dividends declared through the second quarter of 2025, Main Street will have paid 
$44.725 per share in cumulative dividends since its October 2007 initial public offering.

Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure
Not applicable.
Item 9A. Controls and Procedures
(a) Evaluation of Disclosure Controls and Procedures. As of the end of the period covered by this annual report 
on Form 10-K, we carried out an evaluation, under the supervision and with the participation of our management, including 
our Chief Executive Officer, President, Chief Financial Officer, General Counsel and Chief Accounting Officer, 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, General Counsel 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.
(b) Management’s Report on Internal Control Over Financial Reporting. The management of Main Street Capital 
Corporation and its subsidiaries (the Company) is responsible for establishing and maintaining adequate internal control 
over financial reporting, as such term is defined in Exchange Act Rule 13a-15(f). Under the supervision and with the 
participation of management, including the Chief Executive Officer and Chief Financial Officer, the Company conducted 
an evaluation of the effectiveness of the Company’s internal control over financial reporting based on the criteria 
established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the 
Treadway Commission (COSO). Based on the Company’s evaluation under the framework in Internal Control — 
Integrated Framework, management concluded that the Company’s internal control over financial reporting was effective 
as of December 31, 2024. Grant Thornton LLP, the Company’s independent registered public accounting firm, has issued 
an attestation report on the effectiveness of the Company’s internal control over financial reporting as of December 31, 
2024, as stated in its report which is included herein.
(c) Attestation Report of the Registered Public Accounting Firm. Our independent registered public accounting 
firm, Grant Thornton LLP, has issued an attestation report on the effectiveness of our internal control over financial 
reporting, which is set forth above in Reports of Independent Registered Public Accounting Firm in Item 8. Consolidated 
Financial Statements and Supplementary Data of this Annual Report on Form 10-K.
(d) Changes in Internal Control over Financial Reporting. There have been no changes in our internal control 
over financial reporting that occurred during the fiscal quarter ended December 31, 2024 that have materially affected, or 
are reasonably likely to materially affect, our internal control over financial reporting.

Item 9B. Other Information
Fees and Expenses
The following table is being provided to update, as of December 31, 2024, certain information in the Company’s 
effective shelf registration statement on Form N-2 (File No. 333-263258) filed with the SEC on March 3, 2022 as 
supplemented by the prospectus supplements relating to our ATM Program and to the direct stock purchase feature of the 
Plan. The information is intended to assist you in understanding the costs and expenses that an investor in the Company 
will bear directly or indirectly. We caution you that some of the percentages indicated in the table below are estimates and 
may vary. Except where the context suggests otherwise, whenever this Annual Report on Form 10-K contains a reference 
to fees or expenses paid by “you,” “us” or “Main Street,” or that “we” will pay fees or expenses, stockholders will 
indirectly bear such fees or expenses as investors in us.
Stockholder Transaction Expenses:
Sales load (as a percentage of offering price)
 — % (1)
Offering expenses (as a percentage of offering price)
 — % (2)
Dividend reinvestment and direct stock purchase plan expenses
 — % (3)
Total stockholder transaction expenses (as a percentage of offering price)

Annual Expenses of the Company (as a percentage of net assets attributable to common stock):

Acquired fund fees and expenses

Total annual expenses

___________________________
(1) The maximum agent commission with respect to the shares of our common stock sold by us in the ATM Program is 
1.00%. Purchasers of shares of common stock through the direct stock purchase feature of the Plan will not pay any 
sales load. In the event that our securities are sold to or through underwriters, a corresponding prospectus or prospectus 
supplement will disclose the applicable sales load.
(2) Estimated offering expenses payable by us for the estimated duration of the ATM Program are $0.2 million. In the 
event that we conduct an offering of our securities, a corresponding prospectus or prospectus supplement will disclose 
the estimated offering expenses.
(3) The expenses of administering the Plan are included in operating expenses. Additional costs may be charged to 
participants in the direct stock purchase feature of the plan for certain types of transactions.
(4) Total stockholder transaction expenses may include sales load and will be disclosed in a future prospectus or 
prospectus supplement, if any.
(5) Operating expenses in this table represent our estimated expenses.
(6) Interest payments on borrowed funds represent our estimated annual interest payments on borrowed funds based on 
current debt levels as adjusted for projected increases (but not decreases) in debt levels over the next twelve months.
(7) Income tax expense relates to the accrual of (a) deferred tax provision (benefit) primarily related to loss carryforwards, 
timing differences in net unrealized appreciation or depreciation and other temporary book-tax differences from our 
portfolio investments held in Taxable Subsidiaries and (b) excise, state and other taxes. Deferred taxes are non-cash in 
nature and may vary significantly from period to period. We are required to include deferred taxes in calculating our 
annual expenses even though deferred taxes are not currently payable or receivable. Due to the variable nature of 
deferred tax expense, which can be a large portion of the income tax expense, and the difficulty in providing an 
estimate for future periods, this income tax expense estimate is based upon the actual amount of income tax expense 
for the year ended December 31, 2024.
(8) Acquired fund fees and expenses represent the estimated indirect expense incurred due to investments in other 
investment companies and private funds.

Example
The following example demonstrates the projected dollar amount of total cumulative expenses that would be 
incurred over various periods with respect to a hypothetical investment in our common stock. In calculating the following 
expense amounts, we have assumed we would have no additional leverage and that our annual operating expenses would 
remain at the levels set forth in the table above and that you would pay a sales load of up to 1.00% (the commission to be 
paid by us with respect to common stock sold by us in the ATM Program).
1 Year
3 Years
5 Years
10 Years
You would pay the following expenses on a $1,000 investment, 
assuming a 5.0% annual return and no sales load
$ 
88 $ 
255 $ 
408 $

You would pay the following expenses on a $1,000 investment, 
assuming a 5.0% annual return and a 1.00% sales load

The example and the expenses in the table above should not be considered a representation of our future 
expenses, and actual expenses may be greater or less than those shown. While the example assumes, as required by the 
SEC, a 5.0% annual return, our performance will vary and may result in a return greater or less than 5.0%. In addition, 
while the example assumes reinvestment of all dividends at NAV, participants in our dividend reinvestment plan will 
receive a number of shares of our common stock, determined by dividing the total dollar amount of the dividend payable to 
a participant by (i) the market price per share of our common stock at the close of trading on a valuation date determined 
by our Board of Directors for each dividend in the event that we use newly issued shares to satisfy the share requirements 
of the dividend reinvestment plan or (ii) the average purchase price of all shares of common stock purchased by the plan 
administrator in the event that shares are purchased in the open market to satisfy the share requirements of the dividend
