• Interest/payments: semiannual payments on Feb 15 and Aug 15, commencing Feb 15, 2027.

• Covenants & repurchase: Indenture includes covenants tied to compliance with certain Investment Company Act provisions and requires the company to provide financial information if it stops reporting under the Exchange Act. If a change of control occurs and the Notes are rated below investment grade by Fitch, Moody’s and S&P, the company must offer to purchase the Notes at 100% of principal plus accrued interest.
• Underwriting: Offering made under the company’s Form N-2 shelf (Registration No. 333-276252) with an underwriting agreement dated May 7, 2026; BofA Securities acted as representative.

Why It Matters
This raises long-term fixed-rate capital at 5.65%, which can lower near-term reliance on the company’s revolving credit facility and alter interest expense and leverage profiles. The Notes are unsecured, so they rank alongside other unsecured obligations. The covenants and the change-of-control repurchase condition (tied to ratings by the three major agencies) are important protections for noteholders and could affect the company’s flexibility in future transactions. Retail investors should note the maturity, fixed coupon, use of proceeds, and any future changes in credit ratings or control events that could trigger a repurchase.
