Item 1.01 Entry into a Material Definitive Agreement.

On September 11, 2024, Main Street Capital Corporation (“Main Street”) entered into an underwriting agreement (the “Underwriting Agreement”) by and between Main Street and Truist Securities, Inc., as representative of the underwriters named in Schedule A thereto, in connection with the issuance and sale of an additional $100,000,000 in aggregate principal amount (the “Offering”) of Main Street’s 6.50% notes due 2027 (the “New Notes”). The New Notes were issued as additional notes under the Seventh Supplemental Indenture, dated June 4, 2024, between Main Street and The Bank of New York Mellon Trust Company, N.A., as trustee (the “Trustee”), to the indenture, dated April 2, 2013, between Main Street and the Trustee (the “Base Indenture” and, together with the Seventh Supplemental Indenture, the “Indenture”), pursuant to which, on June 4, 2024, Main Street issued $300,000,000 in aggregate principal amount of its 6.50% notes due 2027 (the “Existing 2027 Notes” and, together with the New Notes, the “Notes”). The New Notes are treated as a single series with the Existing 2027 Notes under the Indenture and have the same terms as the Existing 2027 Notes, other than the issue date and offering price.

The New Notes will mature on June 4, 2027 unless previously redeemed or repurchased in accordance with their terms. The New Notes bear cash interest from June 4, 2024, at an annual rate of 6.50% payable semiannually on June 4 and December 4 of each year, beginning on December 4, 2024. The New Notes will have the same CUSIP number and are fungible and rank equally with the Existing 2027 Notes. Including the New Notes, the outstanding aggregate principal amount of Main Street’s 6.50% notes due 2027 is $400,000,000. The New Notes are direct unsecured obligations of Main Street and rank equally in right of payment with Main Street’s existing and future unsecured indebtedness but effectively subordinated to all of Main Street’s outstanding and future secured indebtedness, to the extent of the value of the assets securing such indebtedness, and structurally subordinated to the debt and other obligations of any of Main Street’s subsidiaries, financing vehicles or similar facilities.

Prior to May 4, 2027 (one month prior to the maturity date of the Notes) (the “Par Call Date”), Main Street may redeem the Notes at its option, in whole or in part, at any time or from time to time, at a redemption price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of: (1) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the redemption date (assuming the Notes matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate, as defined in the Indenture, plus 30 basis points less (b) interest accrued to the date of redemption, and (2) 100% of the principal amount of the Notes to be redeemed, plus, in either case, accrued and unpaid interest thereon to the redemption date. On or after the Par Call Date, Main Street may redeem the Notes, in whole or in part, at any time and from time to time, at a redemption price equal to 100% of the principal amount of the Notes being redeemed plus accrued and unpaid interest thereon to the redemption date. In addition, on the occurrence of a “change of control repurchase event,” as defined in the Indenture, holders of the Notes will have the right, at their option, to require Main Street to repurchase for cash some or all of the Notes at a repurchase price equal to 100% of the principal amount of the Notes being repurchased, plus accrued and unpaid interest to, but not including, the repurchase date.

The Indenture contains certain covenants, including covenants requiring Main Street to comply with the asset coverage requirements of Section 18(a)(1)(A), as modified by Section 61(a) of the Investment Company Act of 1940, as amended, whether or not it is subject to those requirements (but giving effect to exemptive relief granted to Main Street by the Securities and Exchange Commission (the “SEC”)), and to provide financial information to the holders of the Notes and the Trustee if Main Street is no longer subject to the reporting requirements under the Securities Exchange Act of 1934, as amended. These covenants are subject to important limitations and exceptions that are described in the Indenture.

The New Notes were issued and sold in a public offering that was made pursuant to Main Street’s effective shelf registration statement on Form N-2 (Registration No. 333-263258) previously filed with the SEC, as supplemented by a preliminary prospectus supplement dated September 11, 2024 and a final prospectus supplement dated September 11, 2024. The offering of New Notes closed and the New Notes were delivered and paid for on September 13, 2024. The net proceeds received by Main Street were approximately $101.3 million, after deducting the underwriting discounts and estimated offering expenses payable by Main Street.

Main Street intends to initially use the net proceeds from the offering of New Notes to repay outstanding indebtedness, including amounts outstanding under its credit facilities.

The foregoing description of the New Notes and the Indenture does not purport to be complete and is qualified in its entirety by reference to (i) the full text of the Underwriting Agreement filed with this Current Report on Form 8-K as Exhibit 1.1, which is incorporated herein by reference, (ii) the full text of the Seventh Supplemental Indenture and the accompanying Form of 6.50% Notes due 2027 , which are filed as Exhibits 4.1 and 4.2 to Main Street’s Current Report on Form 8-K filed on June 4, 2024 (File No. 1-33723) and incorporated herein by reference, and (iii) the full text of the Base

Indenture, a form of which is filed as Exhibit (d)(6) to Main Street’s Post-Effective Amendment No. 2 to its Registration Statement on Form N-2 filed on March 28, 2013 (Reg. No. 333-183555), which is incorporated herein by reference.

Ladies and Gentlemen:

Main Street Capital Corporation, a Maryland corporation (the “Company”), confirms its agreement with the underwriters listed on Schedule A hereto (the “Underwriters”), for whom Truist Securities, Inc. (“Truist”) is acting as representative (in such capacity, the “Representative”), with respect to the issue and sale by the Company and the purchase by the Underwriters, acting severally and not jointly (the “Offering”), of $100,000,000 aggregate principal amount of 6.500% Notes due 2027 (the “Securities”), as set forth on Schedule A hereto.

The Securities will be issued under an indenture dated as of April 2, 2013 (the “Base Indenture”), as supplemented by the Seventh Supplemental Indenture, dated as of June 4, 2024 (the “Seventh Supplemental Indenture” and, collectively with the Base Indenture, the “Indenture”), between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee (the “Trustee”). The Securities will be issued to Cede & Co. as nominee of the Depository Trust Company (“DTC”) pursuant to a blanket letter of representations (the “DTC Agreement”) between the Company and DTC. The Company understands that the Underwriters propose to make a public offering of the Securities as soon as the Underwriters deem advisable after this Agreement has been executed and delivered.

The Company previously issued $300,000,000 principal amount of 6.500% Notes due 2027 (the “Existing Securities”) under the Indenture. The Securities that will be issued and sold by the Company pursuant to this Agreement will constitute an issuance of “Additional Notes” under and as defined in the Indenture. Except as otherwise described in the Prospectus (as defined below), the Securities issued and sold by the Company pursuant to this Agreement will have identical terms to the Existing Securities, and the Securities and the Existing Securities will be treated collectively as a single class of notes for all purposes under the Indenture.

The Company owns (i) 100% of the limited partnership interests in Main Street Mezzanine Fund, LP (“SBIC Fund I”), (ii) 100% of the limited partnership interests in Main Street Capital III, LP (“SBIC Fund III” and together with SBIC Fund I, the “Funds”), (iii) 100% of the equity interests of Main Street Mezzanine Management, LLC, the general partner of SBIC Fund I (“MSGPI”), (iv) 100% of the equity interests of Main Street Capital III GP, LLC, the general partner of SBIC Fund III (“MSGPIII” and together with MSGPI, the “General Partners”), (v) 100% of the equity interests, indirectly, of MSC Adviser I, LLC (“MSCAI”), a registered investment adviser under the Investment Advisers Act of 1940, as amended (the “Advisers Act”), and investment adviser to MSC Income Fund, Inc., and (vi) 100% of the equity interests of Main Street Capital Partners, LLC (the “Investment Advisor” and together with MSCAI, the “Advisors”). The Company, the Funds, the General Partners and the Advisors are collectively referred to as the “Main Street Entities.”

Pursuant to the Investment Company Act of 1940, as amended, and the rules and regulations promulgated thereunder (collectively, the “1940 Act”), the Company has filed with the United States Securities and Exchange Commission (the “Commission”) a Notification of Election to be Subject to Sections 55 through 65 of the 1940 Act filed on Form N-54A (File No. 814-00751) (the “BDC Election”), pursuant to which the Company elected to be treated as a business development company (“BDC”) under the 1940 Act. The Company has elected to be treated for federal income tax purposes as a regulated investment company (“RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”).

Pursuant to the Securities Act of 1933, as amended, and the rules and regulations promulgated thereunder (collectively, the “1933 Act”), the Company has prepared and filed with the Commission a universal shelf registration statement on Form N-2 (File No. 333-263258), including a related base prospectus (the “Base Prospectus”), which registers the offer and sale of the Company’s common stock, preferred stock, subscription rights and debt securities to be issued from time to time in accordance with Rule 415 of the 1933 Act by the Company. Such registration statement became effective immediately upon its filing with the Commission on March 3, 2022. The Company has also filed with the Commission a preliminary prospectus supplement, dated September 11, 2024 (collectively, the Base Prospectus and the preliminary prospectus supplement are the “Preliminary Prospectus”). Promptly after execution and delivery of this Agreement, the Company will prepare and file a prospectus in accordance with the provisions of Rule 430B of the rules and regulations of the Commission under the 1933 Act (the “1933 Act Regulations”) and Rule 424(b) of the 1933 Act Regulations. The information included or incorporated by reference in such prospectus that was omitted from such registration statement at the time it became effective but that is deemed to be part of such registration statement pursuant to Rule 430B is referred to as “Rule 430B Information.” Unless the context otherwise requires, such registration statement, including all documents filed as a part thereof, and including all post-effective amendments thereto filed on or prior to the date hereof and any Rule 430B Information contained in a prospectus relating to the Securities subsequently filed with the Commission pursuant to Rule 424(b) under the 1933 Act and deemed to be part of the registration statement, is herein called the “Registration Statement.” The final prospectus in the form filed by the Company with the Commission pursuant to Rule 424(b) under the 1933 Act on or before the second business day after the date hereof (or such earlier time as may be required

under the 1933 Act), which will include the Base Prospectus, dated March 3, 2022, together with a final prospectus supplement relating to the Securities (the “Prospectus Supplement”), is herein called the “Prospectus.” Any reference herein to the Registration Statement, any Preliminary Prospectus or the Prospectus shall be deemed to refer to and include the documents that are incorporated by reference therein pursuant to the 1933 Act Regulations in effect as of the Applicable Time.

The Preliminary Prospectus, together with the information set forth on Annex I hereto is hereinafter referred to as the “Disclosure Package.”

All references in this Agreement to financial statements and schedules and other information which is “included” or “stated” in the Registration Statement, the Preliminary Prospectus or the Prospectus (each as defined above) (and all other references of like import) shall be deemed to mean and include all such financial statements and schedules and other information which is or is deemed to be incorporated by reference in or otherwise deemed under the rules of the Commission promulgated thereunder or otherwise to be a part of or included in the Registration Statement, the Preliminary Prospectus or the Prospectus, as the case may be, as of any specified date; and all references in this Agreement to amendments or supplements to the Registration Statement, the Preliminary Prospectus or the Prospectus, including those made pursuant to Rule 424, shall be deemed to mean and include, without limitation, the filing of any document under the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder (collectively, the “1934 Act”), which is or is deemed to be incorporated by reference in or otherwise deemed to be a part of or included in the Registration Statement, the Preliminary Prospectus or the Prospectus, as the case may be, as of any specified date.

All references in this Agreement to the Registration Statement, the Preliminary Prospectus, the Prospectus or any amendments or supplements to any of the foregoing, shall include any copy thereof filed with the Commission pursuant to the Electronic Data Gathering Analysis and Retrieval System, or any successor system (“EDGAR”).

Section 1.Representations and Warranties of the Company.

The Company represents and warrants to and agrees with each of the Underwriters, as of the date hereof, the Applicable Time (defined below) and the Closing Time referred to in Section 2(b) hereof, as follows:

(a)Compliance with Registration Requirements.

(i)The Company has prepared and filed with the Commission the Registration Statement. The Company meets the requirements for use of Form N-2 under the 1933 Act. The Registration Statement has become effective under the 1933 Act, and no stop order suspending the effectiveness of the Registration Statement or suspending the use of the Preliminary Prospectus or the Prospectus has been issued, and no proceedings for any such purpose, have been instituted or are pending or, to the knowledge of the Company, are contemplated by the Commission, and

any request on the part of the Commission for additional information with respect thereto has been complied with.

(ii)At the respective times the Registration Statement, and any post-effective amendment thereto, became effective and at the Closing Time, as hereinafter defined, the Registration Statement, and all amendments and supplements thereto, complied and will comply in all material respects with the requirements of the 1933 Act and did not and will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading. Neither the Prospectus nor any amendment or supplement thereto, at the time the Prospectus or any such amendment or supplement thereto was issued and at the Closing Time, included or will include any untrue statement of a material fact or omitted or will omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. The representations and warranties in this subsection shall not apply to statements in or omissions from the Registration Statement or the Prospectus (including any amendments or supplements to the Registration Statement or the Prospectus) made in reliance upon and in conformity with information furnished to the Company in writing by or on behalf of any Underwriter for use in the Registration Statement or the Prospectus (or any amendments or supplements to the Registration Statement or the Prospectus), it being understood and agreed that the only such information furnished to the Company in writing by the Underwriters consists of the information described in Section 6(f) below.

(iii)The Disclosure Package as of the Applicable Time does not include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; each Additional Disclosure Item (as defined in Section 3(f) hereof) listed on Schedule B hereto complied with the requirements pertaining thereto under the 1933 Act, does not and will not conflict in any material respect with the information contained in the Registration Statement or the Disclosure Package and each such Additional Disclosure Item, as supplemented by and taken together with the Disclosure Package as of the Applicable Time, did not and will not include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. As used in this subsection and elsewhere in this Agreement, “Applicable Time” means 1:42 p.m. (Eastern Time) on September 11, 2024; provided that, if, subsequent to the date of this Agreement, the Company and the Underwriters have determined that the Disclosure Package included an untrue statement of material fact or omitted a statement of material fact necessary to make the information therein not misleading, and have agreed, in connection with the public offering of the Securities, to provide an opportunity to purchasers to terminate their old contracts and enter into new contracts, then “Applicable Time” will refer to the information available to purchasers at the time of entry into the first such new contract. The representations and warranties in this subsection shall not apply to statements in or omissions from the Disclosure Package based upon and in conformity with information relating to any Underwriter furnished to the Company in writing by any Underwriter or its representative expressly for use therein, it being understood and agreed that the only such information furnished by the Underwriters to the Company consists of the information described in Section 6(f) below.

(iv)The Preliminary Prospectus when first filed under Rule 424 and as of its date complied in all material respects with the 1933 Act and, if filed by electronic transmission pursuant to EDGAR (except as may be permitted by Regulation S-T under the 1933 Act), was substantially identical to the copy thereof delivered to the Underwriters for use in connection with this Offering. The Prospectus when first filed under Rule 424 and as of its date will comply in all material respects with the 1933 Act and, if filed by electronic transmission pursuant to EDGAR (except as may be permitted by Regulation S-T under the 1933 Act), will be substantially identical to the copy thereof delivered to the Underwriters for use in connection with this Offering.

(b)Independent Accountant. Grant Thornton LLP, who has expressed its opinion with respect to certain of the financial statements (which term as used in this Agreement includes the related notes thereto) and supporting schedules filed with the Commission as part of, or that are incorporated by reference in, the Registration Statement, the Prospectus and the Disclosure Package, is an independent registered public accounting firm as required by the 1933 Act and the 1934 Act, and the rules and regulations of the Public Company Accounting Oversight Board.

(c)Expense Summary. The information set forth in the Base Prospectus under the caption “Fees and Expenses” has been prepared in accordance with the requirements of Form N-2 and, to the extent estimated or projected, such estimates or projections are believed to be reasonably based.

(d)Preparation of the Financial Statements. The consolidated financial statements, together with the related schedules and notes thereto, filed with the Commission as a part of, or incorporated by reference in, the Registration Statement and included in the Prospectus and the Disclosure Package present fairly the consolidated financial position of the Company and its consolidated subsidiaries as of and at the dates indicated and the results of their operations and cash flows for the periods specified. Such financial statements have been prepared in conformity with accounting principles generally accepted in the United States (“GAAP”) applied on a consistent basis throughout the periods involved, except as may be expressly stated in the related notes thereto. Other than the financial statements included in the Registration Statement, no other financial statements or supporting schedules are required to be included therein. All disclosures contained in the Registration Statement, the Disclosure Package or the Prospectus regarding “non-GAAP financial measures” (as such term is defined by the rules and regulations of the Commission) comply with Regulation G under the 1934 Act and Item 10 of Regulation S-K of the 1933 Act, to the extent applicable.

(e)Internal Control Over Financial Reporting. The Company maintains a system of internal control over financial reporting (as such term is defined in Rule 13a-15(f) and 15d-15(f) under the 1934 Act). The Company’s auditors and the audit committee of the Company’s board of directors have been advised of (1) any known significant deficiencies in the design or operation of internal control over financial reporting that could adversely affect the ability to record, process, summarize, and report financial data and (2) any known fraud, whether or not material, that involves management or other employees who have a role in the Company’s internal control

over financial reporting; and any such deficiencies or fraud will not result in a Material Adverse Effect (as defined below). The Company’s internal control over financial reporting is effective and the Company is not aware of any material weakness in its internal control over financial reporting.

(f)Disclosure Controls. The Company has established and maintains disclosure controls and procedures (as such term is defined in Rule 13a-15 and 15d-15 under the 1934 Act) that (i) are designed to ensure that material information relating to the Company, including its consolidated subsidiaries, is made known to the Company’s principal executive officer and its principal financial officer by others within those entities, particularly during the periods in which the periodic reports required under the 1934 Act are being prepared, (ii) will be evaluated for effectiveness as of the end of each fiscal quarter and fiscal year of the Company, and (iii) are effective to perform the functions for which they were established.

(g)No Material Adverse Change in Business. Except as otherwise disclosed in the Registration Statement, the Disclosure Package and the Prospectus, subsequent to the respective dates as of which information is given in the Registration Statement, the Disclosure Package and the Prospectus: (i) there has been no material adverse change, or any development that could reasonably be expected to result in a material adverse change, in the condition, financial or otherwise, or in the earnings, net asset value, prospects, business or operations, whether or not arising from transactions in the ordinary course of business, of the Company, the Funds, the General Partners and the Advisors, considered as one entity (any such change or effect, where the context so requires is called a “Material Adverse Change” or a “Material Adverse Effect”); (ii) the Company, the Funds, the General Partners and the Advisors, considered as one entity, have not incurred any material liability or obligation, indirect, direct or contingent, not in the ordinary course of business or entered into any material transaction or agreement not in the ordinary course of business; and (iii) except for regular distributions paid or declared by the Company to its stockholders consistent with past practice or any other distributions described in the Disclosure Package and the Prospectus, there has been no dividend or distribution of any kind declared, paid or made by the Company.

(h)Good Standing of the Company, the Funds, the General Partners and the Advisors. The Company is duly incorporated and validly existing as a corporation in good standing under the laws of the state of Maryland and has the corporate power and authority to own, lease and operate its properties and to conduct its business as described in the Registration Statement, the Prospectus and the Disclosure Package and to enter into this Agreement, the Indenture, the Securities and the DTC Agreement and perform its obligations hereunder and thereunder. The Company is duly qualified as a foreign corporation to transact business and is in good standing in each jurisdiction in which such qualification is required, whether by reason of the ownership or leasing of property or the conduct of business, except for such jurisdictions where the failure to so qualify or to be in good standing would not, individually or in the aggregate, have a Material Adverse Effect.

Each Fund is a limited partnership duly formed and validly existing as a limited partnership under the laws of the state of Delaware and is duly qualified as a foreign limited

partnership to transact business, and is in good standing in each jurisdiction in which such qualification is required whether by reason of ownership or leasing of property or the conduct of business, except for such jurisdictions where the failure to so qualify or be in good standing would not, individually or in the aggregate, have a Material Adverse Effect.

Each of the General Partners and the Advisors is a limited liability company that is duly formed and validly existing as a limited liability company under the laws of the state of Delaware and is duly qualified as a foreign limited liability company to transact business, and is in good standing in each jurisdiction in which such qualification is required whether by reason of ownership or leasing of property or the conduct of business, except for such jurisdictions where the failure to so qualify or be in good standing would not, individually or in the aggregate, have a Material Adverse Effect.

All of the issued and outstanding limited liability company interests and partnership interests of the General Partners, the Advisors and the Funds, as appropriate, have been duly authorized and validly issued, are fully paid and non-assessable and owned 100% by the Company, directly or indirectly, free and clear of any security interest, mortgage, pledge, lien, encumbrance or claim, other than any liens granted by the Company under one or more of the Company’s credit facilities or financing arrangements as may be described in the Disclosure Package and the Prospectus from time to time (the “Credit Facilities”).

(i)Subsidiaries of the Company. The Company does not own, directly or indirectly, any shares of stock or any other equity or long-term debt securities of any corporation or other entity other than (i) its interests in the Funds, the General Partners, the Advisors, Main Street CA Lending, LLC, Main Street Equity Interests, Inc. and MS Agent Services, LLC; (ii) those corporations or other entities accounted for as portfolio investments in accordance with the Commission’s rules and regulations (each a “Portfolio Company” and collectively, the “Portfolio Companies”); and (iii) 100% of the equity interests in tax blocker subsidiaries and wholly-owned special purpose subsidiaries that directly or indirectly hold interests in one or more Portfolio Companies or whose only assets are cash and cash equivalents.

(j)Portfolio Companies. The Company or the Funds, either directly or indirectly through one or more tax blocker subsidiaries or one or more wholly-owned special purpose subsidiaries, have duly authorized, executed and delivered agreements (each a “Portfolio Company Agreement”) required to make the investments in the Portfolio Companies. Except as otherwise disclosed in the Disclosure Package and the Prospectus, subsequent to the date as of which information is given in the Disclosure Package and the Prospectus, there has been no material increase in the total fair value dollar amount of the Portfolio Company investments on non-accrual status.

(k)Officers and Directors. Except as disclosed in the Prospectus and the Disclosure Package, no person is serving or acting as an officer or director of the Company except in accordance with the applicable provisions of the 1940 Act. Except as disclosed in the Registration Statement, the Disclosure Package and the Prospectus, no director of the Company is (i) an “interested person” (as defined in the 1940 Act) of the Company or (ii) an “affiliated

person” (as defined in the 1940 Act) of any Underwriter listed on Schedule A hereto. For purposes of this Section 1(k), the Company shall be entitled to reasonably rely on representations from such officers and directors.

(l)Business Development Company Election. The Company has filed the BDC Election and, accordingly, has duly elected to be subject to the provisions of Sections 55 through 65 of the 1940 Act. At the time the BDC Election was filed with the Commission, it (i) contained all statements required to be stated therein in accordance with, and complied in all material respects with the requirements of, the 1940 Act and (ii) did not include any untrue statement of material fact or omit to state a material fact necessary to make the statements therein not misleading. The Company has not filed with the Commission any notice of withdrawal of the BDC Election pursuant to Section 54(c) of the 1940 Act, the BDC Election remains in full force and effect, and, to the Company’s knowledge, no order of suspension or revocation of the BDC Election under the 1940 Act has been issued or proceedings therefore initiated or threatened by the Commission. The operations of the Company are in compliance in all material respects with all applicable provisions of the 1940 Act and the rules and regulations of the Commission thereunder, including the provisions applicable to BDCs.

(m)Capitalization. The authorized, issued and outstanding capital stock of the Company is as set forth in the Disclosure Package and the Prospectus. The Company’s common stock, par value $0.01 per share (the “Common Stock”), conforms in all material respects to the description thereof contained in the Disclosure Package and the Prospectus. All issued and outstanding shares of Common Stock have been duly authorized and validly issued and are fully paid and non-assessable, and have been offered and sold or exchanged by the Company in compliance with all applicable laws (including, without limitation, federal and state securities laws). None of the outstanding Common Stock was issued in violation of the preemptive or other similar rights of any security holder of the Company. No shares of preferred stock of the Company have been designated, offered, sold or issued and none of such shares of preferred stock are currently outstanding.

(“FINRA”), or under the rules and regulations of the New York Stock Exchange (“NYSE”). As used herein, a “Repayment Event” means any event or condition which gives the holder of any note, debenture or other evidence of indebtedness (or any person acting on such holder’s behalf) the right to require the repurchase, redemption or repayment of all or a portion of such indebtedness by a Main Street Entity, as applicable.

None of the Main Street Entities have received any notice of infringement or conflict with asserted intellectual property rights of others, which infringement or conflict, if the subject of an unfavorable decision, would result in a Material Adverse Effect. To the Company’s knowledge, none of the technology employed by the Company has been obtained or is being used by the Company in violation of any contractual obligation binding on

the Company or any of its officers, directors or employees or otherwise in violation of the rights of any persons.

All pending legal or governmental proceedings to which any Main Street Entity is a party or of which any of such Main Street Entity’s property or assets is the subject that are not described in the Registration Statement, the Disclosure Package or the Prospectus, including ordinary routine litigation incidental to the business, could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

Item or any amendment or supplement to any of the foregoing, or any notice from the Commission objecting to the use of the form of the Registration Statement or any post-effective amendment thereto, or of the suspension of the qualification of the Securities for offering or sale in any jurisdiction or of the loss or suspension of any exemption from any such qualification, or of the initiation or threatening of any proceedings for any of such purposes, or of any examination pursuant to Section 8(e) of the 1933 Act concerning the Registration Statement and (v) if the Company becomes the subject of a proceeding under Section 8A of the 1933 Act in connection with the Offering. The Company will promptly effect the filings necessary pursuant to Rule 424(b) and will take such steps as it deems necessary to ascertain promptly whether the form of prospectus transmitted for filing under Rule 424(b) was received for filing by the Commission and, in the event that it was not, it will promptly file such prospectus. The Company will make every reasonable effort to prevent the issuance of any stop order and the suspension or loss of any qualification of the Securities for offering or sale and any loss or suspension of any exemption from any such qualification, and if any such stop order is issued, or any such suspension or loss occurs, to obtain the lifting thereof at the earliest possible moment.

The Company will furnish to each Underwriter, without charge, during the period when the Prospectus is required (or, but for the provisions of Rule 172, would be required) to be delivered by applicable law (whether to meet the request of purchasers pursuant to Rule 173(d) or otherwise), such number of copies of the Prospectus and any amendments or supplements to any of the foregoing as such Underwriter may reasonably request.

(e)Continued Compliance with Securities Laws. The Company will use its reasonable best efforts to comply with the applicable provisions of the 1933 Act, the 1933 Act Regulations, the 1934 Act, the 1934 Act Regulations, the 1940 Act and the rules and regulations of the

Commission under the 1940 Act so as to permit the completion of the distribution of the Securities as contemplated by this Agreement, the Disclosure Package and the Prospectus.

If at any time any Additional Disclosure Item conflicts with the information contained in the Registration Statement or if an event shall occur or condition shall exist as a result of which it is necessary (or, if the Representative or counsel for the Underwriters shall notify the Company that, in their reasonable judgment, it is necessary) to amend or supplement such Additional Disclosure Item so that it will not include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made or then prevailing, not misleading, or if it is necessary (or, if the Representative or counsel for the Underwriters shall notify the Company that, in their reasonable judgment, it is necessary) to amend or supplement such Additional Disclosure Item in order to comply with the requirements of the 1933 Act or the 1933 Act Regulations, the Company will promptly notify the Representative of such event or condition and of its intention to file such amendment or supplement or other filing (or, if the Representative or counsel for the Underwriters shall have notified the Company as aforesaid, the Company will promptly notify the Representative of its intention to prepare such amendment or supplement or other filing) and will promptly prepare and, if required by the 1933 Act or the 1933 Act Regulations, file with the Commission, subject to Section 3(b) hereof, such amendment or supplement or other filing as may be necessary to eliminate or correct such conflict, untrue statement or omission or to comply with such

requirements, and the Company will furnish to the Underwriters such number of copies of such amendment or supplement or other filing as the Underwriters may reasonably request.

The Company represents and agrees that, without the prior consent of the Representative, (i) it will not distribute any offering material other than the Registration Statement, the Prospectus, the Disclosure Package and the Additional Disclosure Items, and (ii) other than as set forth in Schedule B hereto, it has not made and will not make any offer relating to the Securities that would constitute a “free writing prospectus” as defined in Rule 405 under the 1933 Act and which the parties agree, for the purposes of this Agreement, includes (x) any “advertisement” as defined in Rule 482 under the 1933 Act; and (y) any sales literature, materials or information provided to investors by, or with the approval of, the Company in connection with the marketing of the Offering, including any in-person road show or investor presentations (including slides and scripts relating thereto) made to investors by or on behalf of the Company (the materials and information referred to in this Section 3(f), other than the Registration Statement, the Prospectus and the Disclosure Package, are herein referred to as an “Additional Disclosure Item”); any Additional Disclosure Item the use of which has been consented to by the Representative is listed on Schedule B hereto.

(g)Amendments or Supplements to the Disclosure Package. If there occurs an event or development as a result of which the Disclosure Package would include an untrue statement of a material fact or would omit to state a material fact necessary in order to make the statements therein, in light of the circumstances then prevailing, not misleading, the Company will promptly notify the Underwriters so that any use of the Disclosure Package may cease until it is amended or supplemented (at the sole cost and expense of the Company).

(h)Blue Sky and Other Qualifications. The Company will use commercially reasonable efforts, in cooperation with the Underwriters, to qualify the Securities for offering and sale, or to obtain an exemption for the Securities to be offered and sold, under the applicable securities laws of such states and other jurisdictions (domestic or foreign) as the Representative may designate and to maintain such qualifications and exemptions in effect for so long as required for the distribution of the Securities (but in no event for less than one year from the date of this Agreement); provided, however, that the Company shall not be obligated to file any general consent to service of process or to qualify as a foreign corporation or as a dealer in securities in any jurisdiction in which it is not so qualified or to subject itself to taxation in respect of doing business in any jurisdiction in which it is not otherwise so subject.

Section 6.Indemnification.

(a)Indemnification of Underwriters. The Company agrees to indemnify, defend and hold harmless each Underwriter, its partners, directors, officers and employees, and any person who controls any Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, and the successors and assigns of all of the foregoing persons, from and against:

(i)any and all loss, damage, expense, liability or claim whatsoever (including the reasonable cost of any investigation incurred in connection therewith) which, jointly or severally, any such Underwriter or any such person may incur under the 1933 Act, the 1934 Act, the 1940 Act, the common law or otherwise, insofar as such loss, damage, expense, liability or claim arises out of or is based upon (A) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto), or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading or (B) any untrue statement or alleged untrue statement of a material fact included in the Disclosure Package or the Prospectus (or any amendment or

supplement thereto), or any Additional Disclosure Item (when taken together with the Disclosure Package), or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

(ii)against any and all loss, damage, expense, liability or claim whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever arises out of or is based upon any such untrue statement or omission referred to in clause (i); provided that (subject to Section 6(d) below) any such settlement is effected with the written consent of the Company; and

(iii)against any and all expense whatsoever, as incurred (including the fees and disbursements of counsel chosen by the Representative), reasonably incurred in investigating, preparing or defending against any actual or threatened litigation (including the fees and disbursements of counsel chosen by the Representative), or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under clauses (i) or (ii) above.

Notwithstanding the foregoing, the indemnification provisions set forth in this Section 6(a) shall not apply to any loss, damage, expense, liability or claim to the extent arising out of or based upon any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished to the Company by any Underwriter through the Representative or its counsel expressly for use in the Registration Statement (or any amendment thereto), the Disclosure Package or the Prospectus (or any amendment or supplement thereto) or any Additional Disclosure Item, it being understood and agreed upon that the only such information furnished by any Underwriter consists of the information set forth in Section 6(f) below.

(b)Indemnification of the Company, Directors and Officers. Each Underwriter severally and not jointly agrees to indemnify and hold harmless the Company, its directors, officers, and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act against any and all loss, damage, expense, liability or claim described in Section 6(a), as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement (or any amendment thereto), the Disclosure Package or the Prospectus (or any amendment or supplement thereto) or any Additional Disclosure Item (when taken together with the Disclosure Package) in reliance upon and in conformity with written information furnished to the Company by such Underwriter through the Representative or its counsel expressly for use in the Registration Statement (or any amendment thereto) or the Disclosure Package or the Prospectus (or any amendment or supplement thereto) or any Additional Disclosure Item, it being understood and agreed upon that the only such information furnished by any Underwriter consists of the information set forth in Section 6(f) below.

(c)Actions against Parties; Notification. Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of this indemnity agreement. In the case of parties indemnified pursuant to Section 6(a), counsel to the indemnified parties shall be selected by the Representative, and, in the case of parties indemnified pursuant to Section 6(b), counsel to the indemnified parties shall be selected by the Company. An indemnifying party may participate at its own expense in the defense of any such action; provided, however, that counsel to the indemnifying party shall not (except with the consent of the indemnified party) also be counsel to the indemnified party. In no event shall the indemnifying parties be liable for fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances. No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 6 or Section 7 hereof (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

(d)Settlement without Consent if Failure to Reimburse. If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 6(a)(ii) effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement; provided that an indemnifying party shall not be liable for any such settlement effected without its consent if such indemnifying party, prior to the date of such settlement, (1) reimburses such indemnified party in accordance with such request for the amount of such fees and expenses of counsel as the indemnifying party believes in good faith to be reasonable, and (2) provides written notice to the indemnified party that the indemnifying party disputes in good faith the reasonableness of the unpaid balance of such fees and expenses.

(e)[Reserved].

(f)Information Provided by Underwriters. The Company and the Underwriters acknowledge and agree that (i) the concession and reallowance figures appearing under the caption “Underwriting (Conflicts of Interest)–Commissions and Discounts” in the Prospectus,

(ii) the statements set forth in the first sentence of each of the first and second paragraphs under the caption “Underwriting (Conflicts of Interest)–Price Stabilization and Short Positions” in the Prospectus, and (iii) the list of Underwriters and their respective participation in the sale of the Securities, which is set forth in the first table under the caption “Underwriting (Conflicts of Interest)” in the Prospectus, constitute the only information furnished in writing by or on behalf of the several Underwriters for inclusion in the Prospectus.

Section 7.Contribution.

If the indemnification provided for in Section 6 hereof is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other hand from the offering of the Securities pursuant to this Agreement or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company on the one hand and of the Underwriters on the other hand in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations.

The relative benefits received by the Company on the one hand and the Underwriters on the other hand in connection with the Offering pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the Offering pursuant to this Agreement (before deducting expenses) received by the Company and the total underwriting discount received by the Underwriters (whether from the Company or otherwise), in each case as set forth on the cover of the Prospectus bear to the aggregate principal offering amount of the Securities as set forth on such cover.

The relative fault of the Company on the one hand and the Underwriters on the other hand shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 7. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 7 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency

or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission.

No Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of any such untrue or alleged untrue statement or omission or alleged omission.

Notwithstanding the provisions of this Section 7, no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

For purposes of this Section 7, each person, if any, who controls an Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as such Underwriter, and each director and officer of the Company and each person, if any, who controls the Company, within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as the Company. The Underwriters’ respective obligations to contribute pursuant to this Section 7 are several in proportion to the number of Securities set forth opposite their respective names on Schedule A hereto and not joint.

Notwithstanding any other provision of Section 6 or this Section 7, any indemnification or contribution by the Company shall be subject to the requirements and limitations of Section 17(i) of the 1940 Act.

Section 8.Representations and Warranties to Survive Delivery.

All representations, warranties and covenants contained in this Agreement or in certificates of officers of the Company submitted pursuant hereto, shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of any Underwriter, any person controlling any Underwriter or any affiliate of any Underwriter, or by or on behalf of the Company, its officers or directors or any person controlling the Company, and shall survive the acceptance of and payment for any of the Securities.

Section 9.Termination of Agreement.

(a)Termination; General. The Underwriters may terminate this Agreement, by notice to the Company, at any time at or prior to the Closing Time (i) if there has been, since the time of execution of this Agreement or since the date of the Prospectus, any Material Adverse Change whether or not arising in the ordinary course of business, or (ii) if there has occurred any material adverse change in the financial markets in the United States or the international financial markets, any material outbreak of hostilities or material escalation thereof or other calamity or crisis or any change or development involving a prospective change in national or international

political, financial or economic conditions, in each case the effect of which is such as to make it, in the judgment of the Underwriters, impracticable or inadvisable to market the Securities or to enforce contracts for the sale of the Securities, or (iii) if trading in the Common Stock has been suspended or materially limited by the Commission or the NYSE, or if trading generally on the NYSE or Nasdaq markets has been suspended or materially limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by any of said exchanges or by such system or by order of the Commission, the NYSE or any other governmental authority, or a material disruption has occurred in commercial banking or securities settlement or clearance services in the United States, or (iv) if a banking moratorium has been declared by either Federal or New York state authorities.

(b)Liabilities. If this Agreement is terminated pursuant to this Section, such termination shall be without liability of any party to any other party except as provided in Section 4 hereof, and provided further that Section 1, Section 6, Section 7, Section 8, Section 11, Section 12 and Section 13 shall survive such termination and remain in full force and effect.

Section 10.Default by One or More of the Underwriters.

(a)If one or more of the Underwriters shall fail at the Closing Time to purchase the Securities which it or they are obligated to purchase under this Agreement (the “Defaulted Securities”), the Representative shall have the right, within 24 hours thereafter, to make arrangements for one or more of the non-defaulting Underwriters, or any other underwriters, to purchase all, but not less than all, of the Defaulted Securities in such amounts as may be agreed upon and upon the terms herein set forth; if, however, the Representative shall not have completed such arrangements within such 24-hour period, then:

(i)if the number of Defaulted Securities does not exceed 10% of the number of Securities to be purchased on such date, each of the non-defaulting Underwriters shall be obligated, severally and not jointly, to purchase the full amount thereof in the proportions that their respective underwriting obligations hereunder bear to the underwriting obligations of all non-defaulting Underwriters, or

(ii)if the number of Defaulted Securities exceeds 10% of the number of Securities to be purchased on such date, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter.

(b)No action taken pursuant to this Section 10 shall relieve any defaulting Underwriter from liability in respect of its default.

(c)In the event of any such default which does not result in a termination of this Agreement either the Representative or the Company shall have the right to postpone the Closing Time for a period not exceeding seven (7) days in order to effect any required changes in the Registration Statement or Prospectus or in any other documents or arrangements. As used herein, the term “Underwriter” includes any person substituted for an Underwriter under this Section 10.

Section 12.Parties.

This Agreement shall each inure to the benefit of and be binding upon the Underwriters, the Company, and their respective partners and successors. Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any person, firm or corporation, other than the Underwriters, the Company, and their respective successors and the controlling persons and officers and directors referred to in Sections 6 and 7 and their heirs and legal representatives, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained. This Agreement and all conditions and provisions hereof are intended to be for the sole and exclusive benefit of the Underwriters, the Company, and their respective partners and successors, and said controlling persons and officers, directors and their heirs and legal representatives, and for the benefit of no other person, firm or corporation. No purchaser of Securities from any Underwriter shall be deemed to be a successor by reason merely of such purchase.

Section 13.No Fiduciary Obligation.

The Company acknowledges and agrees that each of the Underwriters have acted, and are acting, solely in the capacity of an arm’s-length contractual counterparty to the Company with respect to the Offering contemplated hereby (including in connection with determining the terms of the Offering) and not as a financial advisor or a fiduciary to, or an agent of, the Company or

any other person. Additionally, the Underwriters have not advised, and are not advising, the Company or any other person as to any legal, tax, investment, accounting or regulatory matter in any jurisdiction with respect to the transactions contemplated hereby. The Company shall consult with its own advisors concerning such matters and shall be responsible for making its own independent investigation and appraisal of the transactions contemplated hereby, and the Underwriters shall have no responsibility or liability to the Company with respect thereto. Any review by the Underwriters of the Company, the transactions contemplated hereby or other matters relating to such transactions has been and will be performed solely for the benefit of the Underwriters and have not been and shall not be on behalf of the Company or any other person. It is understood that the offering price was arrived at through arm’s-length negotiations between the Underwriters and the Company, and that such price was not set or otherwise determined as a result of expert advice rendered to the Company by any Underwriter. The Company acknowledges and agrees that the Underwriters are collectively acting as an independent contractor, and any duty of the Underwriters arising out of this Agreement and the transactions completed hereby shall be contractual in nature and expressly set forth herein. Notwithstanding anything in this Agreement to the contrary, the Company acknowledges that the Underwriters may have financial interests in the success of the Offering contemplated hereby that are not limited to the difference between the price to the public and the purchase price paid to the Company by the Underwriters for the Securities.

Section 14.Research Analyst Independence.

The Company acknowledges that (i) the Underwriters’ research analysts and research departments are required to be independent from their respective investment banking divisions and are subject to certain regulations and internal policies and (ii) the Underwriters’ research analysts may hold views and make statements or investment recommendations and/or publish research reports with respect to the Company, the value of the Common Stock, the Securities and/or the Offering that differ from the views of their respective investment banking divisions. The Company hereby waives and releases, to the fullest extent permitted by law, any claims that it may have against the Underwriters with respect to any conflict of interest that may arise from the fact that the views expressed by the Underwriters’ independent research analysts and research departments may be different from or inconsistent with the views or advice communicated to the Company by any Underwriter’s investment banking division. The Company acknowledges that each of the Underwriters is a full service securities firm and as such, from time to time, subject to applicable securities laws, may effect transactions for its own account or the account of its customers and hold long or short positions in debt or equity securities of the companies that are the subject of the transactions contemplated by this Agreement.

Section 15.Governing Law and Time.

Section 18.Effect of Headings.

The Article and Section headings herein are for convenience only and shall not affect the construction hereof.

Section 19.Recognition of the U.S. Special Resolution Regimes.

(a)In the event that any Underwriter that is a Covered Entity becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer from such Underwriter of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and any such interest and obligation, were governed by the laws of the United States or a state of the United States.

Ladies and Gentlemen:

We have acted as counsel to Main Street Capital Corporation, a Maryland corporation (the “Company”), in connection with the preparation and filing of a registration statement on Form N-2 (File No. 333-263258) (as amended as of the date hereof, the “Registration Statement”) filed by the Company with the U.S. Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Securities Act”), which became effective immediately upon its filing on March 3, 2022, and the final prospectus supplement, dated September 11, 2024 (including the base prospectus filed therewith, the “Prospectus”), filed with the Commission on September 13, 2024 pursuant to Rule 424 under the Securities Act, relating to the proposed issuance by the Company of an additional $100,000,000 aggregate principal amount of 6.500% notes due 2027 (the “Notes”), to be sold to underwriters pursuant to an underwriting agreement, dated as of September 11, 2024, which is substantially in the form filed as Exhibit 1.1 to the Company’s Current Report on Form 8-K filed with the Commission on September 13, 2024 (the “Underwriting Agreement”).

This opinion letter is being furnished to the Company in accordance with the requirements of Item 25 of Form N-2 under the Securities Act, and we express no opinion herein as to any matter other than as to the legality of the Notes.

The Notes will be issued pursuant to the indenture, incorporated by reference as an exhibit to the Registration Statement, entered into between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee (the “Trustee”), on April 2, 2013, as supplemented by a seventh supplemental indenture, filed as Exhibit 4.1 to the Company’s Current Report on Form 8-K filed with the Commission on June 4, 2024 (collectively, the “Indenture”).

As counsel to the Company, we have participated in the preparation of the Registration Statement and the Prospectus and have examined the originals or copies of the following:

(i)The Articles of Amendment and Restatement of the Company, certified as of the date hereof by an officer of the Company;

(ii)The Amended and Restated Bylaws of the Company, certified as of the date hereof by an officer of the Company;

(iv)The resolutions of the board of directors of the Company, or a duly authorized committee thereof, relating to, among other things, (a) the authorization and approval of the preparation and filing of the Registration Statement, (b) the authorization, execution and delivery of the Indenture; and (c) the authorization, issuance and sale of the Notes, certified as of the date hereof by an officer of the Company;

(v)The Underwriting Agreement;

(vi)The Indenture; and

(vii)A specimen copy of the form of the Notes to be issued pursuant to the Indenture in the form attached to the Indenture.

With respect to such examination and our opinion expressed herein, we have assumed, without any independent investigation or verification, (i) the genuineness of all signatures of persons signing all documents submitted to us for examination in connection with which this opinion is rendered, (ii) the legal capacity of all natural persons, (iii) the authenticity of all documents submitted to us as originals, (iv) the conformity to original documents of all documents submitted to us as conformed or reproduced copies and the authenticity of the originals of such copied documents, (v) the legal power and authority of all persons signing on behalf of the parties to all such documents (other than the Company), (vi) the due authorization, execution and delivery of all documents by the parties thereto (other than the Company), (vii) that all certificates issued by public officials have been properly issued, (viii) that the Indenture will be a valid and legally binding obligation of the parties thereto (other than the Company), (ix) the accuracy and completeness of all corporate records made available to us by the Company, and (x) that at the time of issuance of the Notes, after giving effect to such issuance, the Company will be in compliance with Section 18(a)(1)(A) of the Investment Company Act of 1940, as amended (the “1940 Act”), giving effect to Section 61(a) of the 1940 Act. We also have assumed without independent investigation or verification the accuracy and completeness of all corporate records made available to us by the Company.

As to certain matters of fact relevant to the opinions in this opinion letter, we have relied upon certificates and/or representations of officers of the Company. We have also relied on certificates and confirmations of public officials. We have not independently established the facts, or in the case of certificates or confirmations of public officials, the other statements, so relied upon.

This opinion letter is limited to the contract laws of the State of New York, and, to the extent relevant to the opinion expressed herein, the applicable provisions of the Maryland General Corporation Law, in each case as in effect on the date hereof, and we express no opinion with respect to any other laws of such jurisdictions or the laws of any other jurisdictions.

Based upon and subject to the limitations, exceptions, qualifications and assumptions set forth in this opinion letter, we are of the opinion that, when the Notes are duly executed and delivered by duly authorized officers of the Company and duly authenticated by the Trustee, all in accordance with the provisions of the Indenture, and delivered to the underwriters against payment therefor in accordance with the terms of the Underwriting Agreement, the Notes will constitute valid and legally binding obligations of the Company, enforceable against the Company in accordance with their terms, except as such enforceability may be limited by applicable bankruptcy, insolvency, reorganization, receivership, moratorium, fraudulent conveyance, and other similar laws affecting the rights and remedies of creditors generally and by general principles of equity (including without limitation the availability of specific performance or injunctive relief and the application of concepts of materiality, reasonableness, good faith and fair dealing), regardless of whether considered in a proceeding at law or in equity.

We hereby consent to the filing of this opinion as an exhibit to the Company’s Current Report on Form 8-K filed with the Commission September 13, 2024 and to the reference to our firm in the “Legal Matters” section in the Prospectus. We do not admit by giving this consent that we are in the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations of the Commission thereunder.
