Main Street Capital Corp. Amends Credit Facility, Increases Revolver to $1.24B

What Happened

• Main Street Capital Corporation (MAIN) filed an 8-K reporting that on June 29, 2026 it entered into the Ninth Amendment to its Third Amended and Restated Credit Agreement.
• The amendment, among Main Street, certain guarantors, Truist Bank (administrative agent) and the lenders, increases and extends the company’s corporate credit facility.

Key Details

• Revolving commitments increased to $1,240 million (i.e., $1.24 billion).
• Accordion feature expanded to allow total commitments up to $1,860 million ($1.86 billion).
• Revolving period extended through June 2030; final maturity extended to June 2031.
• Truist affiliates and certain lenders may receive customary fees for investment banking or advisory services.
• Main Street issued a related press release on June 30, 2026; the full amendment is filed as Exhibit 10.1 to the 8-K.

Why It Matters

• Increased revolver capacity and the larger accordion give Main Street more liquidity and optional borrowing capacity, which can help fund new investments or manage cash needs without near-term refinancing.
• The maturity extensions push major repayment obligations further out (revolver to 2030, final maturity to 2031), reducing near-term refinancing risk.
• Investors should note this affects Main Street’s credit profile and available leverage; review the full amendment for any covenant or pricing changes not summarized here.
