Business Context and Reporting Period

Sixth Street Specialty Lending, Inc. (TSLX) is a Delaware corporation regulated as a Business Development Company (BDC) and a Regulated Investment Company (RIC).

This report covers the quarterly period ended June 30, 2021.

Key Financial Metrics

Material Changes vs. Prior Period

• Investment Income Decline: Total investment income decreased by approximately 5.5% year-over-year. This was primarily driven by a significant reduction in prepayment fees (down from $13.8 million to $4.7 million) and accelerated amortization of upfront fees, partially offset by a larger average portfolio size.
• Expense Increase: Net expenses increased to $68.7 million from $61.4 million. Interest expense decreased due to lower LIBOR rates, but management fees and incentive fees related to capital gains increased. Specifically, $10.1 million in incentive fees were accrued related to cumulative unrealized capital gains, compared to none in the prior year.
• Portfolio Growth: The portfolio grew by approximately $271 million in fair value, reaching $2.57 billion. The company funded $265.2 million in new investments during the quarter ended June 30, 2021.
• Capital Markets Activity: The company issued $300 million in 2026 Notes and raised approximately $85.9 million through a common stock offering in February 2021. Proceeds were used to pay down the Revolving Credit Facility.

Guidance, Outlook, and Risks

Management Commentary: Management highlighted that the decrease in investment income was idiosyncratic, driven by specific paydowns and fee structures rather than broader credit trends. The portfolio yield remains stable at 9.8% (fair value). The company continues to focus on direct originations in the middle-market, with 98.9% of debt investments bearing floating rates.

Risks and Contingencies:

• COVID-19 Impact: The filing reiterates risks associated with the ongoing pandemic, including potential impairments to portfolio companies' operations and reduced investment opportunities.
• Leverage: The company operates with leverage, which magnifies returns but also increases the risk of loss. The asset coverage ratio remains well above the 150% regulatory minimum.
• Interest Rate Sensitivity: While the portfolio is largely floating-rate, a decrease in interest rates could compress net investment income if borrowing costs do not decline proportionally or if floors are hit.
• Valuation Risk: A significant portion of the portfolio (Level 3 assets) is valued using unobservable inputs, introducing subjectivity to fair value measurements.

Investor Verification Checklist

• Fee Structure Impact: Verify the impact of the $10.1 million accrued incentive fee on capital gains on future cash flow distributions, as this is a non-cash expense that reduces reported net income.
• Prepayment Fee Volatility: Assess the sustainability of investment income given the sharp decline in prepayment fees and upfront fee amortization compared to the prior year.
• Debt Maturity Profile: Review the maturity schedule of the $1.3 billion debt portfolio, specifically the 2022 Convertible Notes ($142.8 million) and 2023 Notes ($150.0 million), to understand refinancing needs.
• Non-Accrual Status: Confirm the status of the $0.5 million in non-accrual investments (0.0% of portfolio) and any potential charge-offs.
• Unfunded Commitments: Note the $191.1 million in unfunded commitments to current portfolio companies and the company's ability to fund these without breaching asset coverage ratios.
