Key Financial Metrics

Material Changes vs. Prior Period

• Net Investment Income: Increased by $5.6 million (10.7%) year-over-year, driven by a larger average portfolio size and lower interest expense, despite a slight decrease in total investment income.
• Interest Expense: Decreased significantly from $39.0 million to $33.0 million. This was primarily due to a reduction in the weighted average interest rate on debt from 7.6% to 6.4%, resulting from a change in the mix of debt financing and lower SOFR rates.
• Unrealized Gains/Losses: The company reported a net change in unrealized losses of $21.8 million, compared to $7.0 million in the prior year. This was largely driven by $11.0 million in unrealized losses on foreign currency borrowings and widening credit spreads.
• Portfolio Composition: The portfolio remained heavily weighted toward first-lien debt (92.9% of fair value). Non-accrual investments represented 1.2% of the portfolio by fair value, down slightly from 1.4% in the prior period.
• Debt Structure: The company issued $300 million in 2030 Notes in February 2025 and used proceeds to pay down the Revolving Credit Facility. Outstanding principal on the Revolving Credit Facility decreased from $1,004.1 million to $639.2 million.

Guidance, Outlook, and Risks

• Management Commentary: Management noted that 2025 has been marked by global market uncertainty, including inflation concerns, elevated interest rates, and geopolitical instability. The company is actively monitoring tariff developments and their potential impact on portfolio companies.
• Investment Activity: For Q1 2025, the company funded $136.8 million in new investments and had $269.6 million in exits and repayments. The weighted average term for new commitments was 5.2 years.
• Dividends: The company declared total dividends of $0.53 per share for the quarter ($0.46 base + $0.07 supplemental), down slightly from $0.54 per share in Q1 2024.
• Risks: Key risks include economic downturns impairing portfolio company operations, inability to access capital markets, inflation impacting financing costs, and foreign currency fluctuations. The company maintains a 150% asset coverage ratio requirement under the 1940 Act, currently standing at 185.1%.
• Unusual Items: The company recorded a $1.4 million expense for U.S. federal excise tax. Additionally, a $14.2 million "Make-Whole" amount related to a Bed Bath & Beyond investment remains on the balance sheet but has a full valuation allowance applied due to collectability uncertainty.

Investor Verification Checklist

• Verify the sustainability of the reduced weighted average interest rate on debt (6.4%) given the maturity profile of the new 2030 Notes and the Revolving Credit Facility.
• Review the specific portfolio companies contributing to the $11.0 million unrealized loss on foreign currency borrowings to assess exposure to AUD, CAD, SEK, GBP, and EUR fluctuations.
• Confirm the status of the $14.2 million Make-Whole amount related to Bed Bath & Beyond and the likelihood of recovery.
• Monitor the $322.6 million in unfunded portfolio company commitments and the company's ability to fund these without breaching asset coverage covenants.
• Assess the impact of the 1.2% non-accrual portfolio on future net investment income and potential charge-offs.
