#### Filed by Monroe Capital Corporation

#### pursuant to Rule 425 under the Securities Act of 1933

#### and deemed filed under Rule 14a-6 of the Securities Exchange Act of 1934

#### Subject Company: Monroe Capital Corporation

#### File No. of Related Registration Statement 333-290114

This communication relates to a proposed asset sale between Monroe Capital Corporation ("MRCC") and Monroe Capital Income Plus Corporation and subsequent business combination between MRCC and Horizon Technology Finance Corporation ("HRZN"), along with related proposals for which stockholder approval is being sought (collectively, the "Proposals").

On March 6, 2026, HRZN filed the below disclosure with the Securities and Exchange Commission (the "SEC") under cover of a current report on Form 8-K (the "HRZN Form 8-K"), which supplements and updates the combined definitive joint proxy statement for HRZN and MRCC and prospectus of HRZN, dated January 16, 2026 (the "Joint Proxy Statement"), delivered to HRZN's and MRCC's respective stockholders entitled to vote on the applicable Proposals in connection with the Asset Sale and Merger (each as defined below) transactions discussed in the HRZN Form 8-K and the Joint Proxy Statement.

Except as described in the HRZN Form 8-K, the information in this document does not otherwise modify or update any other disclosure presented in the Joint Proxy Statement. To the extent that information in the HRZN Form 8-K differs from, updates or conflicts with information contained in the Joint Proxy Statement, the information in the HRZN Form 8-K is more current. This is the case even if such section of the Joint Proxy Statement is not specifically referenced in the HRZN Form 8-K.

| **Item 8.01.**  | **Other Events.** |

---

On August 7, 2025, Horizon Technology Finance Corporation, a Delaware corporation ("HRZN"), entered into an Agreement and Plan of Merger (the "Merger Agreement") with Monroe Capital Corporation, a Maryland corporation ("MRCC"), HMMS, Inc., a Maryland corporation and wholly owned subsidiary of HRZN ("Merger Sub"), Monroe Capital BDC Advisors, LLC, a Delaware limited liability company and investment adviser to MRCC ("MC Advisors"), and Horizon Technology Finance Management LLC, a Delaware limited liability company and investment adviser to HRZN ("HRZN Advisor").

The Merger Agreement provides that, subject to the conditions set forth in the Merger Agreement, immediately following the consummation of the transactions contemplated in that certain Asset Purchase Agreement (the "Asset Purchase Agreement"), dated August 7, 2025, by and among MRCC, MC Advisors and Monroe Capital Income Plus Corporation ("MCIP"), including the sale by MRCC of all of its investment assets, as well as liabilities with respect to such assets, to MCIP for cash (the "Asset Sale"), as of the applicable effective time (the "Effective Time"), (i) Merger Sub will merge with and into MRCC, with MRCC continuing as the surviving company and as a wholly owned subsidiary of HRZN (the "Initial Merger"), and (ii) immediately following the Initial Merger, MRCC, as the surviving company, will merge with and into HRZN, with HRZN continuing as the surviving company (the "Second Merger", and together with the Initial Merger, collectively, the "Merger").

On January 30, 2026, a putative class action complaint was filed in the Court of Chancery of the State of Delaware (the "Putative Class Action Complaint") against HRZN and certain members of its Board of Directors (the "HRZN Board"). Subsequently, two complaints with substantially similar allegations were filed in the Supreme Court of the State of New York against HRZN and the HRZN Board (together with the Putative Class Action Complaint, the "Merger Complaints"). The Merger Complaints allege, among other things, that the combined definitive joint proxy statement for HRZN and MRCC and prospectus of HRZN filed with the Securities and Exchange Commission (the "SEC") and delivered to HRZN's and MRCC's respective stockholders on January 20, 2026 (the "Joint Proxy Statement") contains materially misleading and incomplete disclosures. The Merger Complaints seek, among other things, that HRZN make supplemental disclosures to address the alleged materially misleading and incomplete disclosures and to enjoin the closing of the Merger.

HRZN and the individual defendants believe that HRZN has previously disclosed all information required to be disclosed to ensure that its stockholders can make an informed vote at the Special Meeting (as defined below) and that the additional disclosures requested by the plaintiffs are not required under applicable law. Accordingly, HRZN and the individual defendants believe the claims asserted in the Merger Complaints are without merit. However, in order to reduce the costs, risks and uncertainties inherent in litigation, and without admitting any liability or wrongdoing, HRZN has determined voluntarily to revise and supplement the Joint Proxy Statement as described in this Current Report on Form 8-K (the "Report"). Nothing in this Report shall be deemed an admission of the legal necessity or materiality under applicable laws of any of the disclosures set forth herein. To the contrary, HRZN and the HRZN Board specifically deny all allegations in the Merger Complaints that any additional disclosure was or is required.

**ON THE RECOMMENDATION OF A SPECIAL COMMITTEE OF THE HRZN BOARD, COMPRISED OF THE INDEPENDENT DIRECTORS OF THE HRZN BOARD, THE HRZN BOARD HAS UNANIMOUSLY RECOMMENDED THAT HRZN STOCKHOLDERS VOTE "FOR" THE MERGER STOCK ISSUANCE PROPOSAL (AS DEFINED IN THE JOINT PROXY STATEMENT). IN ADDITION, THE HRZN BOARD, INCLUDING ALL OF ITS INDEPENDENT DIRECTORS, HAS UNANIMOUSLY RECOMMENDED THAT HRZN STOCKHOLDERS VOTE "FOR" THE DIRECTOR ELECTION PROPOSAL (AS DEFINED IN THE JOINT PROXY STATEMENT).**

These supplemental disclosures will not affect the merger consideration to be issued by HRZN in connection with the Merger or the timing of the special meeting of HRZN stockholders to be held on March 13, 2026 at 2:30 p.m., Eastern Time, at the offices of HRZN, located at 312 Farmington Avenue, Farmington, Connecticut 06032 (the "Special Meeting").

#### Supplemental Disclosures
The following disclosures supplement the disclosures contained in the Joint Proxy Statement and should be read in conjunction with the disclosures contained in the Joint Proxy Statement, which should be read carefully and in its entirety before authorizing a proxy to vote. All page references below are to pages in the Joint Proxy Statement, and terms used below, unless otherwise defined in this Report, have the meanings set forth in the Joint Proxy Statement.

*The following disclosure is added immediately before the heading "Opinion of the HRZN Special Committee's Financial Advisor" on page 74 of the Joint Proxy Statement, which is located in the section of the Joint Proxy Statement titled "The Asset Sale and the Merger":* 

"**Certain Prospective Financial Information Provided by MRCC and HRZN**

Neither MRCC nor HRZN (or HRZN Advisor and MC Advisors on their behalf), as a matter of course, makes public long-term projections as to their respective future investment income, net investment income or other results due to, among other reasons, the inherent uncertainty of the underlying assumptions and estimates. However, each of MC Advisors and HRZN Advisor prepared certain unaudited forecasted financial information, which information was made available to the MRCC Special Committee and the MRCC Board in connection with their evaluation of the proposed Merger and to Houlihan Lokey who was authorized and directed to use and rely upon such information for purposes of providing financial advice to the MRCC Special Committee, and which information was made available to the HRZN Special Committee and the HRZN Board in connection with their evaluation of the proposed Merger, and to Oppenheimer who was authorized and directed to use and rely upon such information for purposes of providing financial advice to the HRZN Special Committee.

The prospective financial information contained in this joint proxy statement/prospectus was prepared for internal use and not with a view to public disclosure and is being included in this joint proxy statement/prospectus only because the prospective financial information was provided to the MRCC Special Committee and HRZN Special Committee in connection with their evaluation of the proposed Merger, and to Houlihan Lokey and Oppenheimer who were authorized and directed to use and rely upon such information for purposes of providing financial advice to the MRCC Special Committee and the HRZN Special Committee, respectively. The summary of the projections and prospective financial information included in this joint proxy statement/prospectus are not being provided to, and are not intended to, influence the decision of MRCC Stockholders to vote for the Asset Sale Proposal and the Merger Proposal or HRZN Stockholders to vote for the Merger Stock Issuance Proposal.

The prospective financial information was not prepared with a view to compliance with the published guidelines of the SEC or the guidelines established by the American Institute of Certified Public Accountants for preparation and presentation of prospective financial information. The prospective financial information does not purport to present operations in accordance with U.S. generally accepted accounting principles, and MRCC's and HRZN's registered public accounting firms have not examined, compiled or otherwise applied procedures to the prospective financial information, and, accordingly, they assume no responsibility for such information.

The prospective financial information provided by MC Advisors and HRZN Advisor on behalf of MRCC and HRZN, respectively, was based solely on the information available to the management of MC Advisors and HRZN Advisor as of June 30, 2025. The inclusion of the prospective financial information in this joint proxy statement/prospectus should not be regarded as an indication that the prospective financial information will be necessarily predictive of actual future results, and the forecasts should not be relied upon as such. None of MRCC, MC Advisors, HRZN, HRZN Advisor or any other person makes any representation to any security holders regarding the ultimate performance of MRCC or HRZN, as applicable, compared to the prospective financial information set forth in this joint proxy statement/prospectus.

The prospective financial information is not fact and reflects numerous assumptions and estimates as to future events made by MC Advisors and HRZN Advisor that were believed to be reasonable at the time the prospective financial information was prepared and other factors such as industry performance and general business, economic, regulatory, market and financial conditions, as well as factors specific to the businesses of MRCC and HRZN, all of which are difficult to predict and many of which are beyond the control of MRCC and HRZN. Other persons attempting to project the future results of MRCC and HRZN will make their own assumptions that could result in projections materially different than those presented in this joint proxy statement/prospectus. In addition, the prospective financial information does not take into account any circumstances or events occurring after June 30, 2025. Further, the prospective financial information does not take into account the effect of any failure to occur of the Transactions. Accordingly, there can be no assurance that the prospective financial information will be realized, and actual results could vary significantly from those reflected in the prospective financial information.

------

Neither MRCC nor HRZN intends to update or otherwise revise the prospective financial information to reflect circumstances existing after June 30, 2025 or to reflect the occurrence of future events even in the event that any or all of the assumptions underlying the prospective financial information are shown to be in error. The projections and prospective financial information in this joint proxy statement/prospectus are forward-looking statements. These statements involve certain risks and uncertainties that could cause actual results to differ materially from those in the forward-looking statements. See "*Special Note Regarding Forward-Looking Statements*".

Each of HRZN Advisor, on behalf of HRZN, and MC Advisors, on behalf of MRCC, provided the HRZN Special Committee, the HRZN Board and the HRZN Special Committee's financial advisor, Oppenheimer, and the MRCC Special Committee, the MRCC Board and the MRCC Special Committee's financial advisor, Houlihan Lokey, with certain forecasts and projections of HRZN and MRCC, on a stand-alone basis, and pro forma for the Transactions that were used in connection with the financial analyses described below. A non-exclusive summary of such forecasts and projections are presented below. Such projections were used by Oppenheimer in performing dividend discount analyses and merger impact analyses for HRZN in connection with Oppenheimer's opinion, as more fully described below in the section entitled "– Opinion of the HRZN Special Committee's Financial Advisor", and by Houlihan Lokey in performing discounted dividend analyses for MRCC in connection with Houlihan Lokey's opinion, as more fully described below in the section entitled "– Opinion of the MRCC Special Committee's Financial Advisor".

All statements, other than historical facts, including but not limited to statements regarding the expected timing of the closing of the proposed transactions; the ability of the parties to complete the proposed transactions considering the various closing conditions; the expected benefits of the proposed transactions such as improved operations, enhanced revenues and cash flow, growth potential, market profile and financial strength; the competitive ability and position of the surviving companies following completion of the proposed transactions; and any assumptions underlying any of the foregoing, are forward-looking statements. Forward-looking statements concern future circumstances and results and other statements that are not historical facts and are sometimes identified by the words "may," "will," "should," "potential," "intend," "expect," "endeavor," "seek," "anticipate," "estimate," "overestimate," "underestimate," "believe," "could," "project," "predict," "continue," "target" or other similar words or expressions. Forward-looking statements are based upon current plans, estimates and expectations that are subject to risks, uncertainties and assumptions. Should one or more of these risks or uncertainties materialize, or should underlying assumptions prove to be incorrect, actual events and results may vary materially from those indicated or anticipated by such forward-looking statements. The inclusion of such statements should not be regarded as a representation that such plans, estimates or expectations will be achieved. Certain factors could cause actual results and conditions to differ materially from those projected, including, without limitation, the uncertainties associated with (i) the timing or likelihood of the proposed transactions closing; (ii) the expected synergies and savings associated with the proposed transactions; (iii) the ability to realize the anticipated benefits of the proposed transactions; (iv) the possibility that one or more of the various closing conditions to the transactions may not be satisfied or waived on a timely basis or otherwise, including risks that a governmental entity may prohibit, delay or refuse to grant approval for the consummation of the proposed transactions, may require conditions, limitations or restrictions in connection with such approvals or that the required approvals by the shareholders of MRCC and/or HRZN may not be obtained; (v) the possibility that competing offers or acquisition proposals will be made; (vi) risks related to diverting management's attention from ongoing business operations; (vii) the combined company's plans, expectations, objectives and intentions, as a result of the transactions; (viii) the future operating results and net investment income, net asset value or distribution projections of MRCC, HRZN or, following the closing of the transactions, the combined company; (ix) the ability of HRZN Advisor to implement its future plans with respect to the combined company; (x) the expected financings and investments and additional leverage that MRCC, HRZN or, following the closing of the transactions, the combined company may seek to incur in the future; (xi) the adequacy of the cash resources and working capital of MRCC, HRZN or, following the closing of the transactions, the combined company; (xii) the risk that shareholder litigation in connection with the proposed transactions may result in significant costs of defense and liability; (xiii) changes in the economy, financial markets and political environment, including the impacts of inflation and interest rates; (xiv) risks associated with possible disruption in the operations of MRCC and/or HRZN or the economy generally due to terrorism, war or other geopolitical conflict, natural disasters, tariffs or public health crises and epidemics; (xv) future changes in laws or regulations (including the interpretation of these laws and regulations by regulatory authorities); (xvi) conditions in MRCC's and HRZN's operating areas, particularly with respect to business development companies or regulated investment companies; and (xvii) other considerations that may be disclosed from time to time in MRCC's and HRZN's publicly disseminated documents and filings. There is no assurance that the market price of HRZN's shares, either absolutely or relative to net asset value, will increase as a result of any share repurchases, to the extent effectuated, or that any repurchase plan will enhance shareholder value over the long term. HRZN and MRCC have based the forward-looking statements included in this communication on information available to it on the date hereof, and neither HRZN, MRCC nor their affiliates assume any obligation to update any such forward-looking statements. Although HRZN and MRCC undertake no obligation to revise or update any forward-looking statements, whether as a result of new information, future events or otherwise, you are advised to consult any additional disclosures that HRZN and MRCC may make directly to you or through reports that they have filed with the SEC, or in the future may file with the SEC, including the Joint Proxy Statement and the Registration Statement (as defined below), annual reports on Form 10-K, quarterly reports on Form 10-Q and current reports on Form 8-K.
