PROXY STATEMENT
2023 ANNUAL MEETING OF STOCKHOLDERS
GENERAL INFORMATION
This proxy statement and accompanying proxy card are being mailed to the stockholders of MSC Income Fund, Inc. (the “Company,” “we,” “us,” or “our”) beginning on May 25, 2023. Our Board of Directors (the “Board”) is soliciting your proxy to vote your shares at our 2023 Annual Meeting of Stockholders (the “Annual Meeting”) to be held on August 10, 2023 in the East-West Conference Rooms at 1330 Post Oak Boulevard, 2nd Floor, Houston, Texas 77056, at 9:00 AM local time.
All properly executed proxies representing shares of common stock, par value $0.001 per share, of the Company (the “Common Stock”) received prior to the Annual Meeting will be voted in accordance with the instructions marked thereon. If a properly executed proxy card is returned with no specification made, the shares of Common Stock will be voted “FOR” the proposal to elect each of the director nominees and “FOR” the proposal to ratify the appointment of Grant Thornton LLP as the Company’s independent registered public accounting firm. Any stockholder who has given a proxy has the right to revoke it at any time prior to its exercise. Stockholders who execute proxies may revoke them with respect to a proposal by attending the annual meeting and voting his or her shares of Common Stock in person, or by submitting a letter of revocation or a later-dated proxy to the Company at the above address prior to the date of the annual meeting.
The Securities and Exchange Commission (the “SEC”) has adopted rules that permit companies and intermediaries, such as brokers, to satisfy the delivery requirements for proxy statements and annual reports with respect to two or more stockholders sharing the same address by delivering a single proxy statement addressed to those stockholders. This process, which is commonly referred to as “householding,” potentially provides extra convenience for stockholders and cost savings for companies.
Brokers may be householding our proxy materials by delivering a single proxy statement and annual report to multiple stockholders sharing an address, unless contrary instructions have been received from the affected stockholders. Once you have received notice from your broker that they will be householding materials to your address, householding will continue until you are notified otherwise or until you revoke your consent. If you did not respond that you did not want to participate in householding, you were deemed to have consented to the process. If at any time you no longer wish to participate in householding and would prefer to receive a separate proxy statement and annual report, or if you are receiving multiple copies of the proxy statement and annual report and wish to receive only one, please notify your broker if your shares are held in a brokerage account or us if you are a stockholder of record. You can notify us by sending a written request to: MSC Income Fund, Inc., Corporate Secretary’s Office, 1300 Post Oak Blvd., 8th Floor, Houston, Texas 77056, or by calling (713) 350-6000. In addition, we will promptly deliver, upon written or oral request to the address or telephone number above, a separate copy of the annual report and proxy statement to a stockholder at a shared address to which a single copy of the documents was delivered.

VOTING INFORMATION
Record Date and Who May Vote
Our Board selected May 18, 2023 as the record date (the “Record Date”) for determining stockholders entitled to vote at the Annual Meeting. As of the close of business on the Record Date, 80,456,816 shares of our Common Stock were outstanding. Each outstanding share of Common Stock entitles its holder to one vote on each matter to be acted on at the Annual Meeting.
1

How to Vote
For shares held of record, you can vote your shares in person at the Annual Meeting or vote now by giving us your proxy. You may give us your proxy by completing the enclosed proxy card and returning it in the enclosed U.S. postage-prepaid envelope, or by calling a toll-free telephone number or using the Internet as further described on the enclosed proxy card. Telephone and Internet voting procedures have been designed to verify your identity through a personal identification or control number and to confirm that your voting instructions have been properly recorded. If you vote using either of these electronic means, you will save us return mail expense.
By giving us your proxy, you will be directing us on how to vote your shares at the Annual Meeting and at any postponement or adjournment thereof. Even if you plan on attending the Annual Meeting, we urge you to vote now by giving us your proxy. This will ensure that your vote is represented at the Annual Meeting. If you do attend the Annual Meeting, you can change your vote at that time, if you then desire to do so.
If your shares are held in street name, the broker or nominee that holds your shares has the authority to vote them, absent your approval, only on the proposal to ratify our appointment of our independent registered public accounting firm. For all other matters to be voted on at the Annual Meeting, the broker or nominee that holds your shares will need to obtain your authorization to vote those shares and has enclosed a voting instruction form with this proxy statement. In either case, they will vote your shares as you direct on their voting instruction form. You can vote by completing the enclosed voting instruction form and returning it in the enclosed U.S. postage prepaid envelope.
If you want to vote your shares in person at the Annual Meeting, you must obtain a valid proxy from your broker or nominee. You should refer to the instructions provided in the enclosed voting instruction form for further information. Additionally, the availability of telephone or Internet voting depends on the voting process used by the broker or nominee that holds your shares.
You may receive more than one proxy statement and proxy card or voting instruction form if your shares are held through more than one account (e.g., through different brokers or nominees). Each proxy card or voting instruction form only covers those shares of Common Stock held in the applicable account. If you hold shares in more than one account, you will have to provide voting instructions as to all your accounts to vote all your shares.
How to Revoke or Change Your Vote
For shares held of record, you may revoke a proxy or change your vote at any time before it is exercised by written notice to our Corporate Secretary, granting a new proxy or by voting in person at the Annual Meeting. Unless you attend the Annual Meeting and vote your shares in person, you should change your vote using the same method (by telephone, Internet or mail) that you first used to vote your shares. That way, the inspectors of election for the meeting will be able to verify your latest vote.
For shares held in street name, you should follow the instructions in the voting instruction form provided by your broker or nominee to change your vote. If you want to change your vote as to shares held in street name by voting in person at the Annual Meeting, you must obtain a valid proxy from the broker or nominee that holds those shares for you.
Quorum
The Annual Meeting will be held only if a quorum exists. The presence at the Annual Meeting, in person or by proxy, of holders of a majority of our outstanding shares of Common Stock as of the Record Date will constitute a quorum. If you attend the meeting or vote your shares using the enclosed proxy card or voting instruction form (including any telephone or Internet voting procedures provided), your shares will be counted toward a quorum, even if you abstain from voting on a particular matter.
If a quorum is not established with respect to any proposal, the Chairman of the Annual Meeting will have the power to adjourn the Annual Meeting from time to time for any reason, including to solicit additional proxies, to a date not more than 120 days after the original record date without notice other than the announcement at the Annual Meeting. Any business that might have been transacted at the Annual Meeting originally called may be transacted at any such adjourned session at which a quorum is present. If sufficient votes in favor of one or more proposals have been received by the time of the Annual Meeting, the proposals may be acted upon and such actions will be final, regardless of any subsequent adjournment to consider other proposals.
2

Broker Non-Votes
If you are the beneficial owner of shares held through a broker or other nominee and do not vote your shares or provide voting instructions, your broker may vote for you on routine proposals but not on non-routine proposals. Therefore, if you do not vote on the non-routine proposals or provide voting instructions, your broker will not be allowed to vote your shares — this will result in a broker non-vote. At the Annual Meeting, brokers will have discretionary authority to vote shares on the ratification of the appointment of our independent registered public accounting firm (ITEM 2), which is the only routine proposal to be presented at the Annual Meeting. If brokers exercise this discretionary voting authority on ITEM 2, such shares will be considered present at the Annual Meeting for quorum purposes and broker non-votes will occur as to the election of directors (ITEM 1), which is considered non-routine.
Proposals to Be Voted on; Vote Required; and How Votes Are Counted
We are asking you to vote on the following:
•the election of all of the members of our Board; and
•the ratification of our appointment of Grant Thornton LLP as our independent registered public accounting firm for the year ending December 31, 2023.
Election of Directors.  The affirmative vote of a plurality of all of the votes cast in person or by proxy at a meeting at which a quorum is present is sufficient to elect a director. The election of directors is a “non-routine” proposal. Votes to “withhold authority” and broker non-votes will not be included in determining the number of votes cast for this proposal and, as a result, will have no effect on the election of nominees, although they will be considered present for the purpose of determining the presence of a quorum. 
Ratification of Independent Registered Public Accounting Firm.  The affirmative vote of a majority of the votes cast at the Annual Meeting, in person or by proxy, is required to ratify the appointment of Grant Thornton LLP to serve as our independent registered public accounting firm. Abstentions and broker non-votes will not be included in determining the number of votes cast and, as a result, will not have any effect on the result of the vote on this item.
We are not aware of any other matters that may be presented or acted on at the Annual Meeting. If you vote by signing and returning the enclosed proxy card or using the telephone or Internet voting procedures, the individuals named as proxies on the card may vote your shares, in their discretion, on any other matter requiring a stockholder vote that comes before the Annual Meeting.
Expenses
The Company will bear all expenses incurred in connection with this proxy solicitation, which we expect to conduct primarily by mail. In addition, our officers and directors and the officers and other personnel of MSC Adviser I, LLC, our investment adviser (our “Adviser”), may solicit your proxy by telephone, by electronic means or in person, for which they will not be separately compensated. We have retained Broadridge Investor Communications Solutions, Inc. (“Broadridge”) to aid in the solicitation of proxies. We will pay Broadridge a fee of approximately $5,000 in addition to variable costs related to the solicitation of proxies as well as reimbursement of its out-of-pocket expenses. We will request banks, brokers, custodians, nominees, fiduciaries and other record holders to forward copies of this proxy statement to people on whose behalf they hold shares of our Common Stock and to request authority for the exercise of proxies by the record holders on behalf of those people. In compliance with the regulations of the SEC, we will reimburse such persons for reasonable expenses incurred by them in forwarding proxy materials to the beneficial owners of shares of our Common Stock.
Confidential Voting
All voted proxies and ballots will be handled to protect your voting privacy as a stockholder. Your vote will not be disclosed except:
•to meet any legal requirements;
•to permit the inspectors of election to tabulate and certify your vote; or
•to adequately respond to your written comments on your proxy card.

ELECTION OF DIRECTORS
(ITEM 1)
Each member of our Board serves until the next annual meeting of stockholders and until his or her respective successor is duly elected and qualifies. Currently, our Board has four members, of whom three are not “interested persons”, as defined in the Investment Company Act of 1940 (the “1940 Act”), of the Company, our Adviser or its parent company Main Street Capital Corporation (“Main Street”). The 1940 Act requires that our Board be composed of a majority of members who are not “interested persons,” as defined in Section 2(a)(19) of the 1940 Act, of the Company or our Adviser.
The term of office of all directors will expire at this year’s Annual Meeting. On the recommendation of the Nominating and Corporate Governance Committee and the nomination of our Board, each of the four nominees named below, all of whom are presently members of our Board, will stand for re-election as directors at the Annual Meeting.
Unless otherwise directed, the persons named as proxies on the enclosed proxy card intend to vote “FOR” the election of the nominees. If any nominee should become unable to serve or, for good cause, will not serve as a director, the shares will be voted for such substitute nominee as may be proposed by our Board. However, we are not aware of any circumstances that would prevent any of the nominees from serving.
Set forth below is certain information (as of the Record Date) with respect to the nominees for election as directors. In addition to the information presented below regarding each nominee’s specific experience, qualifications, attributes and skills that led our Board to the conclusion that he or she should serve as a director, we also believe that all of our director nominees have a reputation for integrity, honesty and adherence to high ethical standards. They each have demonstrated business acumen and an ability to exercise sound judgment, as well as a commitment of service to the Company and our Board. The business address of each nominee listed below is 1300 Post Oak Boulevard, 8th Floor, Houston, Texas 77056.

He previously served on the administrative board of Arthur Andersen LLP and on the board of partners of Andersen Worldwide. He began his career at Arthur Andersen LLP in 1978 and has served in increasing responsibilities in senior management positions, since 1992. Mr. Niemann has served as a director and Chairman of the Audit Committee of Hines Global Income Trust since July 2014 and as the lead independent director since May 2019 and as a director and Chairman of the Audit Committee of Adams Resources & Energy, Inc. since May 2019.

He graduated with a B.A. in Managerial Studies (magna cum laude) and a master’s degree in accounting from Rice University, received a J.D. (summa cum laude) from the South Texas College of Law and an LL.M. in taxation (summa cum laude) from the University of San Francisco School of Law.

We believe that Mr. Niemann’s significant experience in the public accounting industry including over 40 years in various capacities at Arthur Andersen as well as his background in executive and director roles of public and private companies makes him well qualified to serve as one of our directors.
Jeffrey B. Walker
62
2020
Mr. Walker has been an independent director and Chairman of the Audit Committee since October 2020. Mr. Walker retired in May 2020 after a successful 38 year career in public accounting with Arthur Andersen and, more recently, Deloitte Tax, LLP where he held several leadership roles including, most recently, Vice Chairman from 2014 until May 2020. Mr. Walker served as a member of Deloitte LLP’s board from 2011 until 2015 and also served as the Chief Development Officer of Deloitte Tax from 2013 until 2015.

Mr. Walker is a certified public accountant and a member of the AICPA and Texas State Board of CPAs and earned a B.B.A. in Accounting and Economics from the University of Mississippi.

We believe Mr. Walker is qualified to serve on our Board because of his extensive experience and leadership as a long-time and distinguished operating executive and partner at Deloitte and Arthur Andersen.

Interested Director
Mr. Hyzak is an interested person, as defined in the 1940 Act, due to his position as an officer of the Company and our Adviser, as well as Main Street.
Dwayne L. Hyzak
50
2018
Mr. Hyzak has been a member of our Board since June 2020 and has served as our Chief Executive Officer and Chairman since October 2020. Since 2018, Mr. Hyzak has also served as Main Street’s Chief Executive Officer and as a member of Main Street’s board of directors. Mr. Hyzak also serves as a member of Main Street’s management team’s executive and investment committees. Previously, he served as Main Street’s President (2015 until November 2018), Chief Operating Officer (2014 until November 2018), Chief Financial Officer (2011 until 2014) and Senior Managing Director since 2011 and also served in other senior executive positions at Main Street prior to 2011. Prior to its IPO in 2007, Mr. Hyzak served as a Senior Managing Director and in other executive positions of several Main Street predecessor funds and entities, which are now subsidiaries of Main Street. Mr. Hyzak joined Main Street in 2002, becoming one of the founding members of the firm. Prior to joining Main Street, Mr. Hyzak was a Director of Acquisitions and Integration with Quanta Services, Inc. (NYSE: PWR), which provides specialty contracting services to the power, natural gas and telecommunications industries, where he was principally focused on the company’s mergers and acquisitions and corporate finance activities. Previously, Mr. Hyzak was a Manager with Arthur Andersen in its Transaction Advisory Services group. Mr. Hyzak currently serves on the board of directors of Child Advocates, a non-profit organization that trains and supports advocates to serve the interests of abused or neglected children in the greater Houston area.

We believe Mr. Hyzak is qualified to serve on our Board because of his long tenure in leadership roles, currently as Chief Executive Officer of Main Street and previously as President and Chief Operating Officer of Main Street, in which roles he has successfully led Main Street’s lower middle market investment activities, and also previously as Chief Financial Officer of Main Street, along with his extensive experience in investing and managing investments in lower middle market companies, mergers and acquisitions, corporate finance, tax and accounting.


The affirmative vote of a plurality of all of the votes cast in person or by proxy at a meeting at which a quorum is present is sufficient to elect a director. The election of directors is a “non-routine” proposal. Votes to “withhold authority” and broker non-votes will not be included in determining the number of votes cast for this proposal and, as a result, will have no effect on the election of nominees, although they will be considered present for the purpose of determining the presence of a quorum.

THE BOARD RECOMMENDS YOU VOTE “FOR” EACH OF THE NOMINEES
NAMED IN THIS PROXY STATEMENT.

CORPORATE GOVERNANCE
We maintain a corporate governance section on our website which contains copies of the charters for the committees of our Board. The corporate governance section may be found at www.mscincomefund.com under “Governance – Governance Documents” in the “Investors” section of our website. The corporate governance section contains the following documents, which are available in print to any stockholder who requests a copy in writing to MSC Income Fund, Inc., Corporate Secretary’s Office, 1300 Post Oak Blvd., 8th Floor, Houston, Texas 77056:
Audit Committee Charter
Nominating and Corporate Governance Committee Charter
Pricing Committee Charter

In addition, our Code of Business Conduct and Ethics may be found at www.mscincomefund.com under “Governance – Governance Documents” in the “Investors” section of our website and is available in print to any stockholder who requests a copy in writing. Our Board adopted the Code of Business Conduct and Ethics in order to establish policies, guidelines and procedures that promote ethical practices and conduct by the Company and all its officers, directors and other personnel. All officers, directors and Company personnel are responsible for maintaining the level of integrity and for complying with the policies contained in the Code of Business Conduct and Ethics. Company personnel are required to acknowledge that they have received, read and understand the Code of Business Conduct and Ethics and agree to observe the policies and procedures contained therein at the time of hire and annually thereafter. We intend to disclose any substantive amendments to, or waivers from, our Code of Business Conduct and Ethics within four business days of the waiver or amendment through a posting on our website or on a current report on Form 8-K filed with the SEC.
Corporate Governance Highlights
Board Independence    Board and Committee Practices
•3 out of 4 directors are independent
•Regular executive sessions of independent directors
•All of the members of the Audit Committee and Nominating and Corporate Governance Committee are independent directors
•Annual board and committee self-assessments
•Shared risk management oversight by board and committees
Stockholder Rights
•Routine CEO and management succession planning
•Annual election of all directors
•Committee designated to oversee Environmental, Social and Governance (“ESG”) activities and initiatives
•Stockholder right to call a special meeting

Director Independence
While we are not listed on any public securities exchange, we comply with corporate governance rules of the New York Stock Exchange (“NYSE”) requiring listed companies to have a board of directors with at least a majority of independent directors. The NYSE listing standards provide that a director of a business development company (“BDC”) will be considered to be independent if he or she is not an “interested person” of such company, as defined in Section 2(a)(19) of the 1940 Act. The 1940 Act also requires that we, as a BDC, maintain a majority of independent directors on our Board. On an annual basis, each member of our Board is required to complete a questionnaire designed to provide information to assist the Board in determining whether the director is independent under the NYSE’s corporate governance rules, the applicable provisions of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and the 1940 Act. Based on these independence standards and the recommendation of the Nominating and Corporate Governance Committee, our Board has affirmatively determined that each of our directors, other than Mr. Hyzak, is independent under such standards.
Our Board considered certain portfolio investments and other transactions in which our independent directors may have had a direct or indirect interest, including the transactions, if any, described under the heading “Certain Relationships and Related Party Transactions” below, in evaluating each director’s independence under the 1940 Act and NYSE standards, and the Board determined that no such transaction would impact the ability of any director to exercise independent judgment or impair his or her independence.

Communications with the Board
Stockholders or other interested persons may send written communications to the members of our Board, addressed to Board of Directors, c/o MSC Income Fund, Inc., Corporate Secretary’s Office, 1300 Post Oak Blvd., 8th Floor, Houston, Texas 77056. All communications received in this manner will be delivered to one or more members of our Board.
Board Leadership Structure
Mr. Hyzak serves as Chief Executive Officer, Chairman of the Board and a member of our Adviser’s investment committee. The Board believes that Mr. Hyzak is currently best situated to serve as Chairman of our Board given his history with the Company and Main Street, his deep knowledge of the Company’s business and his extensive experience in managing private debt investments in middle market companies and private debt and equity investments in lower middle market companies. The Company’s independent directors bring experience, oversight and expertise from outside the Company and industry, while Mr. Hyzak brings Company-specific and industry-specific experience and expertise. The Board believes that the current leadership structure with Mr. Hyzak serving as Chief Executive Officer and Chairman of the Board promotes strategy development and execution while facilitating effective, timely communication between management and the Board and is optimal for effective corporate governance.
The Board does not have a lead independent director. We are aware of the potential conflicts that may arise when a non-independent director is Chairman of the Board, but believe these potential conflicts are offset by our strong corporate governance practices. Our corporate governance practices include regular meetings of the independent directors in executive session without the presence of interested directors and management, the establishment of an audit committee and a nominating and corporate governance committee, each of which is comprised solely of independent directors, and the appointment of a Chief Compliance Officer, with whom the independent directors meet without the presence of interested directors and other members of management, for administering our compliance policies and procedures.
Board of Directors and its Committees
Board of Directors. Our Board met five times and acted by unanimous written consent 19 times during 2022. All incumbent directors attended at least 75% of the meetings of the Board and of the committees on which they served during 2022 and all directors attended the 2022 Annual Meeting of Stockholders in person. Our Board expects each director to make a diligent effort to attend all Board and committee meetings, as well as each annual meeting of stockholders.
Committees. Our Board currently has, and appoints the members of, standing Audit and Nominating and Corporate Governance Committees. Each of those committees is comprised entirely of independent directors and has a written charter approved by our Board. The current members of the committees are identified in the following table.

The Nominating and Corporate Governance Committee also oversees the Company’s strategy, initiatives, policies and reporting related to ESG activities.

Unless our stockholders allow us to do so, we are prohibited from selling, or issuing pursuant to our dividend reinvestment plan (the “DRIP”), shares of our Common Stock at a price below the then-current net asset value (“NAV”) per share, exclusive of any distributing commission or discount, as applicable. The Pricing Committee is currently responsible for assisting the Board in determining the price at which we issue shares in any private sales and pursuant to the DRIP and ensuring that such price does not contravene this restriction. Additionally, the Pricing Committee is responsible for assisting the Board in determining the price at which we purchase shares pursuant to our share repurchase program. The Pricing Committee considers various factors, including the valuations of our investment portfolio, in determining whether the Company is issuing shares of Common Stock at a price below the then-current NAV per share. During the year ended December 31, 2022, the Pricing Committee met four times.
MSC Adviser Conflicts Committee. Our Adviser maintains a Conflicts Committee that reviews and approves specific matters that may involve conflicts of interest among Main Street and our Adviser’s investment advisory clients, including the Company. The Board has appointed Mr. Kay to represent the Company’s interest as liaison to our Adviser’s Conflicts Committee.
Board and Committee Evaluation Process
Each year, our Board conducts a thorough self-assessment evaluation process. Detailed questionnaires solicit anonymous input from directors regarding the performance and effectiveness of the Board, Board committees, individual directors and interaction with management and provide an opportunity for Board members to identify areas for improvement. The Nominating and Corporate Governance Committee reviews the results and feedback from this process and makes recommendations for improvements as appropriate. The Board has successfully used this process to evaluate Board and Board committee effectiveness and identify opportunities to strengthen the Board.
Director Nomination Process
Our Nominating and Corporate Governance Committee has determined that a candidate for election to our Board must satisfy certain general criteria, including, among other things:
•be an individual of the highest character and integrity and have an inquiring mind, vision, a willingness to ask hard questions and the ability to work professionally with others;
•be free of any conflict of interest that would violate any applicable law or regulation or interfere with the proper performance of the responsibilities of a director;
•be willing and able to devote sufficient time to the affairs of our Company and be diligent in fulfilling the responsibilities of a member of our Board and a member of any committee thereof (including: developing and maintaining sufficient knowledge of our Company and the specialty finance industry in general; reviewing and analyzing reports and other information important to responsibilities of our Board and any committee thereof; preparing for, attending and participating in meetings of our Board and meetings of any committee thereof; and satisfying appropriate orientation and continuing education guidelines); and
•have the capacity and desire to represent the balanced, best interests of our stockholders as a whole and not primarily a special interest group or constituency.
The Nominating and Corporate Governance Committee seeks to identify potential director candidates who will strengthen the Board and will contribute to the overall mix of general criteria identified above. In addition to the general criteria, the Nominating and Corporate Governance Committee considers specific criteria, such as particular
9

skills, experiences (whether in business or in other areas such as public service, academia or scientific communities), areas of expertise, specific backgrounds and other characteristics, that should be represented on the Board to enhance its effectiveness and the effectiveness of its committees. The Nominating and Corporate Governance Committee does not have a formal policy with respect to diversity; however, the Board and the Nominating and Corporate Governance Committee believe that it is essential that the Board members represent diverse experience and viewpoints and a diverse mix of the specific criteria above. The process of identifying potential director candidates includes establishing procedures for soliciting and reviewing potential nominees for directors and for advising those who suggest nominees of the outcome of such review. The Nominating and Corporate Governance Committee also has the authority to retain and terminate any search firm used to identify director candidates.
Any stockholder may nominate one or more persons for election as one of our directors at an annual meeting of stockholders if the stockholder complies with the notice, information and consent provisions contained in our bylaws and any other applicable law, rule or regulation regarding director nominations. Among other requirements set forth in our bylaws, when submitting a nomination to our Company for consideration, a stockholder must provide certain information that would be required to be disclosed under applicable SEC rules in connection with the solicitation of proxies for election of a director in an election contest, including the following minimum information for each director nominee: full name, age and address; number of any shares of our stock beneficially owned by the nominee, if any; the date such shares were acquired and the investment intent of such acquisition; whether such stockholder believes the nominee is an “interested person” of the Company, as defined in 1940 Act; and all other information required to be disclosed in solicitations of proxies for election of directors in an election contest or is otherwise required, including the nominee’s written consent to being named in the proxy statement as a nominee and to serving as a director if elected. See “Stockholders’ Proposals” in this proxy statement and the relevant provisions of our bylaws for other requirements of stockholder proposals.
The Nominating and Corporate Governance Committee will consider candidates identified through the processes described above and will evaluate each of them, including incumbents, based on the same criteria. The Nominating and Corporate Governance Committee also takes into account the contributions of incumbent directors as Board members and the benefits to us arising from their experience on our Board. Although the Nominating and Corporate Governance Committee will consider candidates identified by stockholders, the Nominating and Corporate Governance Committee may determine not to recommend those candidates to our Board and our Board may determine not to nominate any candidates recommended by the Nominating and Corporate Governance Committee. No director nominee named in this proxy statement was nominated by stockholders.
Board’s Role in the Oversight of Risk Management
Our Board as a whole has responsibility for 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. Areas of focus include competitive, economic, operational, financial (accounting, credit, liquidity and tax), legal, regulatory, compliance and other risks.
Our Adviser has an enterprise risk management program designed to help us identify, categorize, assess, mitigate and manage various risks facing our business. Members of our Adviser’s executive management team monitor and update each risk, regularly reassess the program and the risks identified to align with Company strategy and report on progress thereof to the Audit Committee, which is responsible for overseeing the program.
10

The Board and its committees oversee risks associated with their respective principal areas of focus, as summarized below. Committees meet in executive session with key management personnel regularly and with representatives of outside advisers as necessary.
Board/Committee    Primary Areas of Risk Oversight
Full BoardStrategic, financial and execution risks and exposures associated with the annual operating plan; major litigation and regulatory exposures and other current matters that may present material risk to our operations, plans, prospects or reputation; material acquisitions and divestitures; risks and exposures associated with leadership assessment, director compensation programs and arrangements and review and approval of our Investment Advisory Agreement (defined below) with our Adviser.
Audit CommitteeRisks and exposures associated with financial matters, particularly investment valuation including oversight of the valuation designee pursuant to Rule 2a-5 under the 1940 Act, financial reporting and disclosure, tax, accounting, oversight of independent accountants, internal control over financial reporting, related party transactions, financial policies and credit and liquidity matters, along with information technology systems and policies including data privacy and security and business continuity and operational risks.
Nominating and Corporate Governance Committee
Risks and exposures relating to our programs and policies relating to legal compliance, corporate governance, director nomination, evaluation and succession planning, executive officer evaluation and succession planning and oversight of ESG activities.

Succession Planning
Our Board is actively engaged in succession planning for Board members and key personnel. Its succession planning efforts are led by the Nominating and Corporate Governance Committee for key personnel and non-interested Board members, both overseen by the full Board. These activities include an ongoing evaluation of our Adviser’s talent and leadership.
Hedging and Speculative Trading, Pledging of Company Securities
Our insider trading policy prohibits all directors, officers and personnel from, directly or indirectly, trading while in the possession of material nonpublic information related to the Company’s securities and from engaging in short sales and short-term or other speculative trading of our securities and any transactions that hedge or offset, or are designed to hedge or offset, any decrease in the market value of securities issued by us. Prohibited hedging activity includes market transactions in puts, calls and other derivatives and the purchase of prepaid variable forward contracts, equity swaps and collars. Pledging our securities in a margin account or as collateral for a loan is also prohibited under the policy except in limited circumstances that are pre-approved by our chief compliance officer.
11

Responsible Investment and Community Involvement
We believe that thoughtful consideration of ESG matters provides meaningful value to our personnel, portfolio companies, stockholders and community. We believe that our commitment to implementing, maintaining and consistently seeking to improve business practices mindful of ESG matters will have a lasting positive impact on all of our key stakeholders. Therefore, we are dedicated to taking ESG principals into account with respect to our corporate activities, including in the evaluation of investments. Our Adviser incorporates ESG principals into its investment diligence and evaluation processes. ESG topics considered for any particular business can vary, but can include use of natural resources, compliance with environmental regulation and best practices, gender and ethnic diversity and inclusion practices, community outreach and support and governance policies and practices, among others. These ESG considerations evaluated are part of the total underwriting information considered by our investment teams and investment committee and positive or negative findings with respect to any or all ESG factors will not be dispositive in an investment decision.

Compensation Discussion and Analysis
None of our executive officers receives direct compensation from us. The compensation of the principals and other investment professionals of our Adviser is paid by our Adviser or its affiliates. The compensation of our executive officers for administrative services provided to the Company is paid by our Adviser, but we reimburse our Adviser for, among other things, our allocable portion of the actual cost (without markup) of the persons performing the functions of chief financial officer and chief compliance officer and other personnel engaged to provide such administrative services (including, without limitation, direct compensation costs including the allocable portion of salaries, bonuses, benefits and other direct costs associated therewith) and related overhead costs, including rent.
Our Adviser waived reimbursement of all costs and expenses related to our day-to-day administration and management not related to advisory services, whether such administrative services were performed by a third-party service provider or our Adviser or its affiliates (to the extent performed by our Adviser or its affiliates, the “Internal Administrative Services”) from October 30, 2020 through December 31, 2021. On January 1, 2022, our Adviser assumed responsibility of certain administrative services that were previously provided for us by a third-party sub-administrator. After December 31, 2021, our Adviser continued to waive reimbursement of all Internal Administrative Services expenses, except for the cost of the services previously provided by the sub-administrator. See “Certain Relationships and Related Party Transactions, and Director Independence” below for a discussion of fees and expenses payable to our Adviser.
The Board has not established a standing compensation committee because the executive officers of the Company do not receive any direct compensation from the Company.

AUDIT COMMITTEE REPORT
The Audit Committee is appointed by the Board to review the Company’s financial matters. Each member of the Audit Committee meets the independence requirements established by the 1940 Act and under the applicable SEC rules. As the Audit Committee, we are responsible for the selection, engagement, compensation, retention and oversight of the Company’s independent registered public accounting firm. We are also responsible for recommending to the Board that the Company’s audited financial statements be included in its annual report on Form 10-K for the fiscal year.
In making our recommendation that the Company’s financial statements be included in its annual report on Form 10-K for the year ended December 31, 2022, we have taken the following steps:
•We discussed with Grant Thornton LLP, or Grant Thornton, the Company’s independent registered public accounting firm for the year ended December 31, 2022, those matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board and the SEC. These communications and discussions are intended to assist us in overseeing the financial reporting and disclosure process.
•We conducted periodic executive sessions with Grant Thornton, with no members of the Company’s management present during those discussions. Grant Thornton did not identify any material audit issues, questions or discrepancies, other than those previously discussed with management, which were resolved to the satisfaction of all parties.
•We received and reviewed the written disclosures and the letter from Grant Thornton required by the applicable requirements of the Public Company Accounting Oversight Board regarding Grant Thornton’s communications with us concerning independence and we discussed with Grant Thornton its independence from the Company and its Adviser. We also considered whether the provision of non-audit services to the Company is compatible with Grant Thornton’s independence.
•We determined that there were no former Grant Thornton employees, who previously participated in the Company’s audit, engaged in a financial reporting oversight role at the Company or its Adviser.
•We reviewed and discussed with the Company’s management and Grant Thornton the Company’s audited consolidated balance sheet at December 31, 2022, and consolidated statements of income, changes in net assets and cash flows for the year ended December 31, 2022.
Based on the reviews and actions described above, we recommended to the Board that the Company’s audited financial statements be included in its annual report on Form 10-K for the year ended December 31, 2022 for filing with the SEC.

Our Board has ratified the decision of the Audit Committee to appoint Grant Thornton LLP to serve as the independent registered public accounting firm to audit our financial statements for the year ending December 31, 2023. No determination has been made as to what action the Audit Committee and the Board would take if our stockholders fail to ratify the appointment. Even if the appointment is ratified, the Audit Committee retains discretion to appoint a new independent registered public accounting firm at any time if the Audit Committee concludes such a change would be in the best interests of the Company. We expect that representatives of Grant Thornton LLP will be present at the Annual Meeting and will have an opportunity to make a statement if they desire to do so and to respond to appropriate questions.
For the fiscal years ended December 31, 2022 and 2021, we incurred the following fees for services provided by Grant Thornton, including expenses:

Audit Fees.  Audit fees include fees for services that normally would be provided by the accountant in connection with statutory and regulatory filings or engagements and that generally only the independent accountant can provide. In addition to fees for the audit of our annual financial statements and the review of our quarterly financial statements in accordance with generally accepted auditing standards, this category contains fees for comfort letters, statutory audits, consents and assistance with and review of documents filed with the SEC.
Audit Related Fees.  Audit related fees are assurance related services that traditionally are performed by the independent accountant, such as attest services that are not required by statute or regulation.
Tax Fees.  Tax fees include corporate and subsidiary compliance and consulting.
All Other Fees.  Fees for other services would include fees for products and services other than the services reported above.
During the fiscal years ended December 31, 2022 and 2021, Grant Thornton LLP did not bill any non-audit fees for services rendered to us or for services rendered to our Adviser or its parent company, Main Street.
Pre-approval Policies and Procedures

Our Audit Committee did not rely on the de minimis exception for any of the fees disclosed above.
All services performed for us by Grant Thornton LLP for the fiscal years ended December 31, 2022 and 2021 were pre-approved or ratified by our Audit Committee.

CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS
We have procedures in place for the review, approval and monitoring of transactions involving us and certain persons related to us. As a BDC, the 1940 Act restricts us from participating in transactions with any persons affiliated with us, including our or our Adviser’s officers, directors and personnel and any person controlling or under common control with us or our Adviser, subject to certain exceptions. In addition, the Audit Committee reviews and considers related party transactions.
In addition, our Code of Business Conduct and Ethics, which is applicable to all of our personnel, officers and directors, requires that all personnel, officers and directors avoid any conflict, or the appearance of a conflict, between an individual’s personal interests and our interests. Our Code of Business Conduct and Ethics is available at www.mscincomefund.com under “Governance – Governance Documents” in the “Investors” section of our website.
Our Investment Adviser
We are managed by our Adviser, a registered investment adviser under the Investment Advisers Act of 1940, as amended (the “Advisers Act”), 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 and its subsidiaries. Our Adviser or its affiliate provided investment sub-advisory services to us since our inception through October 30, 2020. On October 30, 2020, we entered into the Investment Advisory and Administrative Services Agreement (the “Investment Advisory Agreement”) with our Adviser, which states that our Adviser will oversee the management of our activities and is responsible for making investment decisions with respect to, and providing day-to-day management and administration of, our investment portfolio.
Pursuant to the Investment Advisory Agreement, we pay our Adviser a base management fee and incentive fees as compensation for the services described above. The base management fee is calculated at an annual rate of 1.75% of our average gross assets. The term “gross assets” means our total assets as disclosed on our consolidated balance sheets. “Average gross assets” are calculated based on our gross assets at the end of the two most recently completed calendar quarters. The base management fee is payable quarterly in arrears. The base management fee is expensed as incurred.
The incentive fee under the Investment Advisory Agreement consists of two parts. The first part, referred to as the subordinated incentive fee on income, is calculated and payable quarterly in arrears based on Pre-Incentive Fee Net Investment Income (as defined below) for the immediately preceding quarter. The subordinated incentive fee on income is equal to 20.0% of our Pre-Incentive Fee Net Investment Income for the immediately preceding quarter, expressed as a quarterly rate of return on adjusted capital at the beginning of the most recently completed calendar quarter, exceeding 1.875% (or 7.5% annualized), subject to a “catch up” feature (as described in more detail in our annual report on Form 10-K for the year ended December 31, 2022).
For this purpose, Pre-Incentive Fee Net Investment Income means interest income, dividend income and any other income (including any other fees such as commitment, origination, structuring, diligence and consulting fees or other fees that we receive from portfolio companies) accrued during the calendar quarter, minus our operating expenses for the quarter (including the management fee, expenses payable under any proposed administration agreement and any interest expense and dividends paid on any issued and outstanding preferred stock, but excluding taxes and the incentive fee). Pre-Incentive Fee Net Investment Income includes, in the case of investments with a deferred interest feature (such as original issue discount debt instruments and PIK interest and zero coupon securities), accrued income that we have not yet received in cash. Pre-Incentive Fee Net Investment Income does not include any realized capital gains, realized capital losses or unrealized capital appreciation or depreciation. For purposes of this fee, adjusted capital means cumulative gross proceeds generated from sales of our common stock (including proceeds from the Company’s dividend reinvestment plan (“DRIP”)) reduced for non-liquidating distributions, other than distributions of profits, paid to our stockholders and amounts paid for share repurchases pursuant to our share repurchase program. The subordinated incentive fee on income is expensed in the quarter in which it is incurred.
The second part of the incentive fee, referred to as the incentive fee on capital gains, is an incentive fee on realized capital gains earned from our portfolio and is determined and payable in arrears as of the end of each calendar year (or upon termination of the Investment Advisory Agreement). This fee equals 20.0% of our incentive fee capital gains, which equals our realized capital gains on a cumulative basis from inception, calculated as of the end of each calendar year, computed net of all realized capital losses and unrealized capital depreciation on a cumulative basis, less the aggregate amount of any previously paid capital gain incentive fees. At the end of each reporting period, we estimate the incentive fee on capital gains and accrues the fee based on a hypothetical liquidation of its portfolio. Therefore, the accrual includes both net realized gains and net unrealized gains (the net
22

unrealized difference between the fair value and the par value of its portfolio), if any. The incentive fee accrued pertaining to the unrealized gain is neither earned nor payable to our Adviser until such time it is realized.

For the year ended December 31, 2022, we incurred base management fees of $19.8 million, subordinated incentive fees on income of $2.1 million and did not incur any capital gains incentive fees.
Our stockholders and our Board, which consists of a majority of non-interested directors, have approved the Investment Advisory Agreement, including the fee structure thereunder. The Investment Advisory Agreement was last renewed by the vote of a majority of the members of the Board who are not “interested persons,” as defined under the 1940 Act, of us or our Adviser, at its meeting on August 11, 2022.
Expense Waiver
Pursuant to the Investment Advisory Agreement, we are required to pay or reimburse our Adviser for administrative services expenses, which include all costs and expenses related to our day-to-day administration and management not related to advisory services, whether such administrative services were performed by a third-party service provider or our Adviser or its affiliates (to the extent performed by our Adviser, or its affiliates, the “Internal Administrative Services”). Internal Administrative Services include, but are not limited to, the cost of our Adviser’s personnel performing accounting and compliance functions and other administrative services on our behalf.
Our Adviser waived reimbursement of all Internal Administrative Services expenses from October 30, 2020 through December 31, 2021. On January 1, 2022, our Adviser assumed responsibility of certain administrative services that were previously provided for us by a third-party sub-administrator. After December 31, 2021, our Adviser continued to waive reimbursement of all Internal Administrative Services expenses, except for the cost of the services previously provided by the sub-administrator. For the year ended December 31, 2022 we incurred Internal Administrative Services expenses of $5.1 million before expense waivers. For the year ended December 31, 2022, our Adviser waived the reimbursement of Internal Administrative Services expenses of $4.5 million. Waived Internal Administrative Services expenses are permanently waived and are not subject to future reimbursement.
Allocation of Our Adviser’s Time
We rely on our Adviser to manage our day-to-day activities and to implement our investment strategy. Our Adviser and certain of its affiliates are presently, and plan in the future to continue to be, involved with activities which are unrelated to us. Additionally, except for certain restrictions on our Adviser set forth in the Investment Advisory Agreement, our Adviser and its affiliates are not restricted from forming additional investment funds, from entering into other investment advisory relationships or from engaging in other business activities, even though such activities may be in competition with us and/or may involve substantial time and resources of our Adviser. As a result of these activities, our Adviser and certain of its affiliates and their personnel will have conflicts of interest in allocating their time between us and other activities in which they are or may become involved. Therefore, our Adviser, and certain of its affiliates and their personnel may experience conflicts of interest in allocating management time, services, and functions among us and any other business ventures in which they or any of their key personnel, as applicable, are or may become involved. This could result in actions that are more favorable to other affiliated entities than to us. However, our Adviser believes that it and its affiliates have sufficient personnel to discharge fully their responsibilities to all activities in which they are involved.
Indemnification
The Investment Advisory Agreement provides that our Adviser and its officers, directors, controlling persons and any other person or entity affiliated with it acting as our agent are entitled to indemnification (including reasonable attorneys’ fees and amounts reasonably paid in settlement) for any liability or loss suffered by such indemnitee, and such indemnitee will be held harmless for any loss or liability suffered by us, if (i) the indemnitee has determined, in good faith, that the course of conduct which caused the loss or liability was in our best interests, (ii) the indemnitee was acting on behalf of or performing services for us, (iii) the liability or loss suffered was not the result of negligence, willful malfeasance, bad faith or misconduct by the indemnitee or an affiliate thereof acting as our agent and (iv) the indemnification or agreement to hold the indemnitee harmless is only recoverable out of our net assets and not from our stockholders.

Co-Investment Transactions
In the ordinary course of business, we enter into transactions with other parties that may be considered related party transactions. We have implemented certain policies and procedures, both written and unwritten, to ensure that we do not engage in any prohibited transactions with any persons affiliated with us. If such affiliations are found to exist, we seek Board and/or appropriate Board committee review and approval for such transactions and otherwise comply with, or seek, orders for exemptive relief from the SEC, as appropriate.
We have received an exemptive order from the SEC permitting co-investments among us, Main Street and other funds and clients advised by our Adviser in certain negotiated transactions where co-investing would otherwise be prohibited under the 1940 Act. We have made co-investments, and in the future intend to continue to make co-investments with Main Street and other funds and clients advised by our Adviser, in accordance with the conditions of the order. The order requires, among other things, that our Adviser and Main Street consider whether each such investment opportunity is appropriate for us, Main Street and the other funds and clients advised by our Adviser, as applicable, and if it is appropriate, to propose an allocation of the investment opportunity between such parties. Because our Adviser is wholly-owned by Main Street and is not managing our investment activities as its sole activity, this may provide our Adviser an incentive to allocate opportunities to other participating funds and clients instead of us. However, our Adviser has policies and procedures in place to manage this conflict, including oversight by the independent members of the Board. Additional information regarding the operation of the co-investment program is set forth in the order granting exemptive relief, which may be reviewed on the SEC’s website at www.sec.gov. 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.
Sales of Common Stock to Main Street
On May 2, 2022, we sold 94,697 shares of our Common Stock to Main Street at $7.92 per share, the price at which we issued new shares in connection with reinvestments of the May 2, 2022 dividend pursuant to the DRIP, for total proceeds to the Company of $750,000. The issuance and sale were made pursuant to the exemption from registration under Section 4(a)(2) of the Securities Act of 1933, as amended (the “Securities Act”), and was unanimously approved by the Board, including each director who is not an “interested person,” as such term is defined in Section 2(a)(19) of the 1940 Act, of us or the Adviser.
On May 1, 2023, we sold 255,754 shares of our Common Stock to Main Street at $7.82 per share, the price at which we issued new shares in connection with reinvestments of the May 1, 2023 dividend pursuant to the DRIP, for total proceeds to the Company of $2,000,000. The issuance and sale were made pursuant to the exemption from registration under Section 4(a)(2) of the Securities Act and was unanimously approved by the Board, including each director who is not an “interested person,” as such term is defined in Section 2(a)(19) of the 1940 Act, of us or the Adviser.
