HOUSTON, November 28, 2022 – Main Street Capital Corporation (NYSE: MAIN) (“Main Street”) is pleased to announce that its wholly owned subsidiary, MSCC Funding I, LLC (the “SPV”), entered into a senior secured revolving credit facility (the “Revolving Credit Facility”) led by Truist Bank (“Truist”), with Truist serving as administrative agent and as one of three initial lenders under the facility. The Revolving Credit Facility provides for $240 million of aggregate initial commitments with an accordion feature that allows for increases up to $450 million of total commitments from new and existing lenders on the same terms and conditions as the existing commitments. Commitments under the Revolving Credit Facility are revolving through November 21, 2025 and mature on November 21, 2027. Advances under the Revolving Credit Facility bear interest at one-month Term SOFR plus a 0.10% credit spread adjustment plus an applicable margin of 2.50% during the reinvestment period and 2.625% and 2.75% during the first and second years of the amortization period, respectively.

Borrowings under the Revolving Credit Facility are being used to purchase certain investments and participation interests from Main Street and to finance the SPV’s direct investments thereafter. The SPV’s obligations to the lenders under the Revolving Credit Facility are secured by a first priority security interest in all of the SPV’s assets but are non-recourse to Main Street.
