SEC Form 425 filed by Monroe Capital Corporation

I encourage you to join me in casting your vote as soon as possible for the proposals being presented at our upcoming stockholder meeting.

If both of the proposals are approved, the Board of Directors believes the transactions described in the proposals will unlock immediate and tangible value for our stockholders by realizing significant value, while also enabling an exchange into Horizon shares in a tax-efficient manner.

In addition, the Board of Directors believes the transactions create compelling long-term upside by positioning our stockholders to participate in Horizon’s larger, more scalable platform supported by a significant capital infusion to propel the next phase of growth.

Your vote is important regardless of how many shares you own and make a critical contribution to the successful outcome of our stockholders’ meeting.

Thank you for your continued support and participation.

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 or distribution projections of MRCC, HRZN or, following the closing of the transactions, the combined company; (ix) the ability of Horizon Technology Finance Management LLC (“HTFM”) 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 Securities and Exchange Commission (the “SEC”), or in the future may file with the SEC, including the Joint Proxy Statement and the Registration Statement (each as defined below), annual reports on Form 10-K, quarterly reports on Form 10-Q and current reports on Form 8-K.
