Revenue is generated primarily through interest income from floating rate secured loans, supplemented by PIK income, dividend income from equity holdings, and income from controlled affiliate JV investments.

Revenue model

1. Interest income from loan portfolio: The primary revenue stream is interest income generated from a diversified portfolio of secured debt instruments (first lien senior secured loans, second lien loans, unitranche, subordinated debt). The majority of debt investments are floating rate securities tied to SOFR, generating variable interest income. Interest is paid quarterly or semi-annually depending on the instrument. Total investment income for FY 2025 was $273.2 million.
2. Dividend and PIK income from portfolio companies: The company earns dividend income from preferred equity and equity interests in portfolio companies, as well as PIK (payment-in-kind) income where interest accrues as additional loan principal rather than being paid in cash. PIK income was $21.6 million for the nine months ended September 30, 2025.
3. Net realized and unrealized gains/losses on investments: Realized gains/losses arise from the sale or repayment of investments. Unrealized gains/losses reflect mark-to-market changes in the fair value of the investment portfolio. FY 2025 reported net realized loss of $33.3 million. Q1 2026 net realized and unrealized losses were $24.0 million.
4. Income from strategic joint ventures: The company earns interest, dividend, and equity income through controlled affiliate investments in joint ventures including the International Senior Loan Program (ISLP) with Pantheon and the Senior Loan Program (SLP) with Amberstone. Controlled affiliate investment income was $39.7 million for the nine months ended September 30, 2025.
