Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Principal Business	Organization and Principal Business Monroe Capital Corporation (together with its subsidiaries, the “Company”) is an externally managed, non-diversified, closed-end management investment company and has elected to be regulated as a business development company (“BDC”) under the Investment Company Act of 1940, as amended (the “1940 Act”). The Company’s investment objective is to maximize the total return to its stockholders in the form of current income and capital appreciation through investment in senior secured, junior secured and unitranche secured (a combination of senior secured and junior secured debt in the same facility in which the Company syndicates a “first out” portion of the loan to an investor and retains a “last out” portion of the loan) debt and, to a lesser extent, unsecured subordinated debt and equity co-investments in preferred and common stock and warrants. The Company is managed by Monroe Capital BDC Advisors, LLC (“MC Advisors”), a registered investment adviser under the Investment Advisers Act of 1940, as amended. In addition, for U.S. federal income tax purposes, the Company has elected to be treated as a regulated investment company (“RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”). The Company currently qualifies and intends to qualify annually to be treated as a RIC for U.S. federal income tax purposes. On October 21, 2024, certain affiliates, including but not limited to Monroe Capital Management Advisors, LLC (“MC Management”), Monroe Capital Investment Holdings, L.P. (the parent of MC Advisors), and Monroe Capital Intermediate Holdings, LLC (any such affiliate, collectively, “Monroe”), entered into an equity purchase agreement, pursuant to which Momentum US Bidco LLC, an affiliate of Wendel SE (collectively, with its affiliates, “Wendel”), agreed to acquire a 75% interest in Monroe, which would constitute a change of control of MC Advisors (the “Adviser Change in Control”). The Adviser Change in Control became effective on March 31, 2025. See Note 6 for additional information. On August 7, 2025, the Company entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Horizon Technology Finance Corporation, a Delaware corporation (“HRZN”), HMMS, Inc., a Maryland corporation and wholly owned subsidiary of HRZN (“Merger Sub”), MC Advisors, and Horizon Technology Finance Management LLC, a Delaware limited liability company and investment adviser to HRZN. The Merger Agreement provides that, subject to the conditions set forth in the Merger Agreement, immediately following the Asset Sale (as defined below) and at the effective time of the Merger (the “Effective Time”), Merger Sub will merge with and into the Company, with the Company continuing as the surviving company and as a wholly-owned subsidiary of HRZN and, immediately thereafter, the Company will merge with and into HRZN, with HRZN continuing as the surviving company (collectively, the “Merger”). On August 7, 2025, the Company entered into an Asset Purchase Agreement (the “Asset Purchase Agreement”) with Monroe Capital Income Plus Corporation, a Maryland corporation (“MCIP”), and MC Advisors, pursuant to which, subject to the satisfaction or waiver of the closing conditions set forth in the Asset Purchase Agreement, on the closing date of the transactions contemplated by the Asset Purchase Agreement (the “Closing Date”), MCIP will acquire the investment assets of the Company at fair value, as determined shortly before the Closing Date, for cash (the “Asset Sale” and together with the Merger, the “Transactions”). Under the Asset Purchase Agreement, the Asset Sale is contingent upon, and will become effective immediately prior to the effectiveness of, the Merger. Following the Asset Sale, the Company’s assets will be the net cash proceeds from the sale after giving effect to the receipt of proceeds from the Asset Sale, repayment of liabilities, transaction costs and distribution of undistributed net investment income. Pursuant to and subject to the terms and conditions of the Merger Agreement, subsequent to the closing of the Asset Sale, the Company will merge with HRZN. See Note 6 for additional information on the Merger and the Asset Sale.
