Reports Financial Results for the Quarter Ended September 30, 2024

Results for the Quarter Ended September 30, 2024 and Other Recent Highlights:

New York, NY — November 7, 2024 — MidCap Financial Investment Corporation (NASDAQ: MFIC) or the “Company,” today announced financial results for the quarter ended September 30, 2024. The Company’s net investment income was $0.44 per share for the quarter ended September 30, 2024, compared to $0.45 per share for the quarter ended June 30, 2024. The Company’s net asset value (“NAV”) was $15.10 per share as of September 30, 2024.

On November 6, 2024, the Board declared a dividend of $0.38 per share payable on December 26, 2024 to stockholders of record as of December 10, 2024.

Mr. Tanner Powell, the Company’s Chief Executive Officer stated, “This quarter MFIC successfully closed its mergers with AFT and AIF which we believe will create significant long-term value for our stockholders. Our focus is on exiting the acquired non-directly originated assets and prudently deploying the investment capacity created from the mergers into directly originated middle market loans. We are fortunate to have access to all the necessary origination to deploy this capital, thanks to the significant volume of loans originated by MidCap Financial, a leading middle market lender with one of the largest direct lending teams in the U.S. and which is managed by Apollo.”

Mr. Powell added, “For the quarter, we produced solid net investment income despite the modest amount of fee and prepayment income, reflecting the impact of the total return feature in our incentive fee structure, which resulted in a partial incentive fee for the quarter. NAV declined during the quarter due to the $0.20 per share special distribution paid in connection with the mergers as well as a modest net loss on the portfolio.”

SHARE REPURCHASE PROGRAM *

During the three months ended September 30, 2024, the Company did not repurchase any shares.

Since the inception of the share repurchase program and through November 6, 2024, the Company repurchased 15,593,120 shares at a weighted average price per share of $15.91, inclusive of commissions, for a total cost of $248.1 million, leaving a maximum of $26.9 million available for future purchases under the current Board authorization of $275 million.

LIQUIDITY

As of September 30, 2024, the Company’s outstanding debt obligations, excluding deferred financing cost and debt discount of $6.1 million, totaled $1.779 billion which was comprised of $350 million of Senior Unsecured Notes (the “2025 Notes”) which will mature on March 3, 2025, $125 million of Senior Unsecured Notes (the “2026 Notes”) which will mature on July 16, 2026, $80 million of Senior Unsecured Notes (the “2028 Notes”) which will mature on December 15, 2028, $232 million outstanding Class A-1 Notes under the CLO and $991.9 million outstanding under the Facility. As of September 30, 2024, $15.8 million in standby letters of credit were issued through the Facility. The available remaining capacity under the Facility was $697.3 million as of September 30, 2024, which is subject to compliance with a borrowing base that applies different advance rates to different types of assets in the Company’s portfolio.

On October 17, 2024, the Company amended and extended the Facility. Lender commitments under the Amended Senior Secured Facility will increase from $1.705 billion to $1.815 billion until December 22, 2024 and will decrease to $1.660 billion thereafter. The Amended Senior Secured Facility includes an “accordion” feature that allows the Company to increase the size of the Facility to $2.723 billion.

The final maturity date under the Amended Senior Secured Facility for extending lenders was extended by over a year from April 19, 2028 to October 17, 2029. The covenants and representations and warranties the Company is required to comply with were also modified (including, among other things, that the minimum stockholders’ equity test was reset), but the remaining material business terms and conditions of the Amended Senior Secured Facility remain substantially the same. The Amended Senior Secured Facility continues to include usual and customary events of default for senior secured revolving credit facilities of this type.

Borrowings under the Amended Senior Secured Facility (and the incurrence of certain other permitted debt) continue to be subject to compliance with a Borrowing Base that applies different advance rates to different types of assets in the Company’s portfolio. The advance rate applicable to any specific type of asset in the Company’s portfolio depends on the relevant asset coverage ratio as of the date of determination. Borrowings under the Amended Senior Secured Facility continue to be subject to the leverage restrictions contained in the Investment Company Act of 1940, as amended (the “1940 Act”). Terms used in this disclosure have the meanings set forth in the Amended Senior Secured Facility.

MERGERS

On July 22, 2024, the Company completed its mergers of AFT and AIF. Pursuant to the AFT Merger Agreement, AFT Merger Sub was first merged with and into AFT, with AFT continuing as the surviving company, and, following the effectiveness of the AFT First Merger, AFT was then merged with and into the Company, with the Company continuing as the surviving company. In accordance with the terms of the AFT Merger Agreement, at the effective time of the AFT First Merger, each outstanding share of common stock, par value $0.001 per share, of AFT was converted into the right to receive 0.9547 shares of common stock, par value $0.001 per share of the Company (with AFT stockholders receiving cash in lieu of fractional shares of the Company). Pursuant to the AIF Merger Agreement, AIF Merger Sub was first merged with and into AIF, with AIF continuing as the surviving company, and, following the effectiveness of the AIF First Merger, AIF was then merged with and into the Company, with the Company continuing as the surviving company. In accordance with the terms of the AIF Merger Agreement, at the effective time of the AIF First Merger, each outstanding share of common stock, par value $0.001 per share, of AIF was converted into the right to receive 0.9441 shares of common stock, par value $0.001 per share of the Company (with AIF stockholders receiving cash in lieu of fractional shares of the Company). As a result of the Mergers, the Company issued an aggregate of 28,527,003 shares of its common stock to former AFT and AIF stockholders.

The Mergers were considered asset acquisitions under generally accepted accounting principles with the Company being the accounting survivor. The Mergers were accounted for under the asset acquisition method of accounting by the Company in accordance with ASC 805. Under asset acquisition accounting, acquiring assets in groups not only requires ascertaining the cost of the asset (or net assets), but also allocating that cost to the individual assets (or individual assets and liabilities) that make up the group. Per ASC 805-50-30-1, assets are recognized based on their cost to the acquiring entity, which generally includes transaction costs of the asset acquisition, and no gain or loss is recognized unless the fair value of noncash assets given as consideration differs from the assets’ carrying amounts on the acquiring entity’s records. ASC 805-50-30-2 provides that asset acquisitions in which the consideration given is cash are measured by the amount of cash paid. However, if the consideration given is not in the form of cash (that is, in the form of noncash assets, liabilities incurred, or equity interests issued), measurement is based on the cost to the acquiring entity or the fair value of the assets (or net assets) acquired, whichever is more clearly evident and, thus, more reliably measured.

The Company determined the fair value of the shares of the Company’s common stock that were issued to former AFT and AIF stockholders pursuant to the AFT Merger Agreement and AIF Merger Agreement plus transaction costs to be the consideration paid in connection with the Mergers under ASC 805. The consideration paid to AFT and AIF stockholders was less than the aggregate fair values of the AFT and AIF assets acquired and liabilities assumed, which resulted in a purchase discount (the “purchase discount”). Since the fair value of the net assets acquired exceeded the merger consideration paid by the Company, the Company recognized a deemed contribution from Investment Adviser.
