April 09, 2026

Main Street Capital Corporation, a Maryland-incorporated business development company trading on the New York Stock Exchange under the ticker MAIN, disclosed on April 9, 2026, that it has entered into a Master Note Purchase Agreement with qualified institutional investors for the issuance of $150 million in aggregate principal amount of 6.93 percent Series A Senior Notes due April 15, 2031.

Note Terms

The notes carry a fixed interest rate of 6.93 percent per year, with interest payable semiannually on April 15 and October 15, beginning October 15, 2026. The notes mature on April 15, 2031, unless redeemed, purchased, or prepaid earlier. Main Street may redeem the notes in whole or in part at any time at par plus accrued interest and, if applicable, a make-whole premium. The company is also obligated to offer prepayment at par plus accrued interest if certain change-of-control events occur.

The Series A Notes are general unsecured obligations that rank equally with all of Main Street’s outstanding and future unsecured, unsubordinated indebtedness.

Use of Proceeds

Main Street intends to use the proceeds to repay outstanding borrowings under its corporate revolving credit facility and its special purpose vehicle revolving credit facility, to make investments consistent with its investment objective and strategies, to invest in marketable securities and idle funds investments, to pay operating expenses and other cash obligations, and for general corporate purposes.

Covenants and Protections

The Note Purchase Agreement includes customary covenants for senior unsecured notes issued in a private placement, including information reporting requirements, maintenance of Main Street’s status as a business development company under the Investment Company Act of 1940, a minimum asset coverage ratio, and a minimum consolidated net worth. The agreement also provides for interest rate step-ups if certain credit-related events occur, including a below-investment-grade event, a secured debt ratio event, or an unsecured debt coverage ratio event.

The notes were offered in reliance on Section 4(a)(2) of the Securities Act of 1933 and have not been registered under federal or state securities laws. The agreement was dated April 8, 2026, and the disclosure was signed by Jason B. Beauvais, Main Street’s General Counsel.
