On November 12, 2025, Main Street Capital Corporation ("Main Street") entered into an equity distribution

agreement (the "Huntington Equity Distribution Agreement") with Huntington Securities, Inc. ("Huntington") on

substantially the same terms as Main Street's equity distribution agreements, each dated March 4, 2025 (together with the

Huntington Equity Distribution Agreement, the "Equity Distribution Agreements"), entered into with each of Truist

Securities, Inc., RBC Capital Markets, LLC, Raymond James & Associates, Inc. and B. Riley Securities, Inc. (together

with Huntington, the "Sales Agents") for the purpose of adding Huntington as an additional Sales Agent under Main

Street's existing "at the market" program equity offering. Under the Equity Distribution Agreements, Main Street may, but

has no obligation to, issue and sell up to 20,000,000 shares of its common stock, par value $0.01 per share (the "Shares"),

from time to time through the Sales Agents, or to them, as principal for their own account.

Further details regarding the Equity Distribution Agreements and the "at the market" program equity offering are

set forth in Main Street's Current Report on <u>[Form 8-K filed with the Securities and Exchange Commission (the "SEC") on](https://www.sec.gov/ix?doc=/Archives/edgar/data/0001396440/000139644025000033/main-20250304.htm)</u>

<u>[March 5, 2025](https://www.sec.gov/ix?doc=/Archives/edgar/data/0001396440/000139644025000033/main-20250304.htm)</u>, which is incorporated herein by reference.

The foregoing description of the Equity Distribution Agreements is not complete and is qualified in its entirety by

reference to the full text of the Equity Distribution Agreements, a form of which was previously filed as Exhibit 1.1 to

Main Street's Current Report on Form 8-K filed with the SEC on March 5, 2025 and is incorporated herein by reference.

The "at the market" program equity offering described in this Item 1.01 will be made pursuant to a prospectus

supplement, dated March 4, 2025, and the related prospectus, dated February 28, 2025, each as supplemented from time to

time, which constitute a part of Main Street's effective shelf registration statement on Form N-2 (File No. 333-285405) that

was filed with the SEC on February 28, 2025.

This Current Report on Form 8-K shall not constitute an offer to sell or a solicitation of an offer to buy any

securities, nor shall there be any sale of these securities in any state or jurisdiction in which such an offer, solicitation or

sale would be unlawful prior to registration or qualification under the securities laws of any such state or other jurisdiction.
