Main Street Capital Corporation entered into an underwriting agreement on October 27, 2026, to issue $500.0 million in aggregate principal amount of senior notes. The notes, with a 6.55% annual interest rate, are due to mature on January 15, 2030.
The offering closed on October 29, 2026, and the notes were issued under a Ninth Supplemental Indenture with The Bank of New York Mellon Trust Company, N.A., as trustee. The notes bear interest at an annual rate of 6.55%, payable semiannually on January 15 and July 15 of each year, beginning on July 15, 2027.
Main Street received approximately $493.0 million in net proceeds after deducting underwriting discounts and estimated offering expenses. The company intends to use these proceeds to repay outstanding indebtedness, including amounts under its credit facilities.
The notes are direct unsecured obligations of Main Street and rank equally with the company's existing and future unsecured indebtedness. However, they are structurally subordinated to the debt and obligations of Main Street's subsidiaries and financing vehicles. The indenture governing the notes includes covenants requiring Main Street to comply with asset coverage requirements and to provide financial information to holders and the trustee.
Main Street may redeem the notes in whole or in part prior to December 15, 2029, at a price equal to the greater of the present value of remaining payments plus 30 basis points over the Treasury Rate or 100% of the principal amount. Holders also have the right to require Main Street to repurchase the notes in the event of a change of control.
