Insights

Main Street adds $200M of fixed-rate 6.95% 2029 notes and refinances debt.

Main Street Capital has expanded its 6.95% notes due 2029 by $200,000,000, bringing the total for this series to $550,000,000. The notes are unsecured obligations, ranking equally with other unsecured debt but behind any secured borrowings and subsidiary-level obligations.

The company reports net proceeds of about $202.8 million, which it intends to use initially to repay existing indebtedness, including credit facility balances. That shifts borrowings toward longer-term, fixed-rate funding at 6.95%, while reducing exposure to shorter-term loans.

The notes include standard investor protections: an optional issuer redemption, a make-whole call before February 1, 2029, and a 100% cash put at par plus interest upon a defined change of control repurchase event, all governed by covenants in the Indenture tied to asset coverage requirements.

material definitive agreement regulatory
"Item 1.01 Entry into a Material Definitive Agreement."
A material definitive agreement is a legally binding contract that creates major, long‑term obligations or rights for a company, such as loans, asset sales, mergers, or supplier deals. Think of it like a mortgage or lease for a business: it can change future cash flow, risk and control, so investors watch these agreements closely because they can materially affect a company’s value, financial health and stock price.
Indenture financial
"the “Base Indenture” and, together with the Sixth Supplemental Indenture, the “Indenture”"
An indenture is a legal agreement between a company that borrows money by issuing bonds and the people who buy those bonds. It explains the rules the company must follow, like paying back the money and keeping certain financial promises. This document helps both sides understand their rights and responsibilities.
change of control repurchase event financial
"on the occurrence of a “change of control repurchase event,” as defined in the Indenture"
shelf registration statement regulatory
"pursuant to Main Street’s effective shelf registration statement on Form N-2"
A shelf registration statement is a document a company files with regulators that allows it to sell shares or bonds quickly when it’s a good time to raise money. It’s like having a pre-approved plan ready so the company can act fast without going through lengthy paperwork each time they want to sell, making fundraising more flexible.
asset coverage requirements financial
"covenants requiring Main Street to comply with the asset coverage requirements of Section 18(a)(1)(A)"
A rule or covenant that specifies the minimum value of a company’s assets that must be held to back its debts, obligations or issued securities. It’s like a lender or regulator asking someone to keep enough cash in the bank to cover outstanding loans; for investors, stronger asset coverage means lower risk of loss if the company faces trouble, while weak coverage raises default or dilution concerns.

Item 1.01    Entry into a Material Definitive Agreement.
On March 27, 2026, Main Street Capital Corporation (“Main Street”) entered into an underwriting agreement (the “Underwriting Agreement”) by and between Main Street and RBC Capital Markets, LLC, as representative of the underwriters named on Schedule A thereto, in connection with the issuance and sale of an additional $200,000,000 in aggregate principal amount (the “Offering”) of Main Street’s 6.95% notes due 2029 (the “New Notes”). The New Notes were issued as additional notes under the Sixth Supplemental Indenture, dated January 12, 2024, between Main Street and The Bank of New York Mellon Trust Company, N.A., as trustee (the “Trustee”), to the indenture, dated April 2, 2013, between Main Street and the Trustee (the “Base Indenture” and, together with the Sixth Supplemental Indenture, the “Indenture”), pursuant to which, on January 12, 2024, Main Street issued $350,000,000 in aggregate principal amount of its 6.95% notes due 2029 (the “Existing 2029 Notes” and, together with the New Notes, the “Notes”). The New Notes are treated as a single series with the Existing 2029 Notes under the Indenture and have the same terms as the Existing 2029 Notes, other than the issue date and offering price.
The New Notes will mature on March 1, 2029 unless previously redeemed or repurchased in accordance with their terms. The New Notes bear cash interest from March 1, 2026, at an annual rate of 6.95% payable semiannually on March 1 and September 1 of each year, beginning on September 1, 2026. The New Notes have the same CUSIP number and are fungible and rank equally with the Existing 2029 Notes. Including the New Notes, the outstanding aggregate principal amount of Main Street’s 6.95% notes due 2029 is $550,000,000. The New Notes are direct unsecured obligations of Main Street and rank equally in right of payment with Main Street’s existing and future unsecured indebtedness but effectively subordinated to all of Main Street’s outstanding and future secured indebtedness, to the extent of the value of the assets securing such indebtedness, and structurally subordinated to the debt and other obligations of any of Main Street’s subsidiaries, financing vehicles or similar facilities.
Prior to February 1, 2029 (one month prior to the maturity date of the Notes) (the “Par Call Date”), Main Street may redeem the Notes at its option, in whole or in part, at any time or from time to time, at a redemption price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of: (1)  (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the redemption date (assuming the Notes matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate, as defined in the Indenture, plus 45 basis points less (b) interest accrued to the date of redemption, and (2) 100% of the principal amount of the Notes to be redeemed, plus, in either case, accrued and unpaid interest thereon to the redemption date. On or after the Par Call Date, Main Street may redeem the Notes, in whole or in part, at any time and from time to time, at a redemption price equal to 100% of the principal amount of the Notes being redeemed plus accrued and unpaid interest thereon to the redemption date. In addition, on the occurrence of a “change of control repurchase event,” as defined in the Indenture, holders of the Notes will have the right, at their option, to require Main Street to repurchase for cash some or all of the Notes at a repurchase price equal to 100% of the principal amount of the Notes being repurchased, plus accrued and unpaid interest to, but not including, the repurchase date.
The Indenture contains certain covenants, including covenants requiring Main Street to comply with the asset coverage requirements of Section 18(a)(1)(A), as modified by Section 61(a) of the Investment Company Act of 1940, as amended, whether or not it is subject to those requirements (but giving effect to exemptive relief granted to Main Street by the Securities and Exchange Commission (the “SEC”)), and to provide financial information to the holders of the Notes and the Trustee if Main Street is no longer subject to the reporting requirements under the Securities Exchange Act of 1934, as amended. These covenants are subject to important limitations and exceptions that are described in the Indenture.
The New Notes were issued and sold in a public offering that was made pursuant to Main Street’s effective shelf registration statement on Form N-2 (Registration No. 333-285405) previously filed with the SEC, as supplemented by a preliminary prospectus supplement dated March 27, 2026 and a final prospectus supplement dated March 27, 2026. The Offering closed and the New Notes were delivered and paid for on March 31, 2026. The net proceeds received by Main Street were approximately $202.8 million, after deducting the underwriting discounts and estimated offering expenses payable by Main Street.
Main Street intends to initially use the net proceeds from the Offering to repay outstanding indebtedness, including amounts outstanding under its credit facilities.
