Key Financial Metrics

Material Changes vs. Prior Period

• Portfolio Growth: The portfolio fair value increased by approximately $222.7 million (9.7%) to $2.52 billion, driven by new investment commitments of $1.12 billion and a reduction in exits/repayments relative to funding.
• Investment Composition: First-lien debt investments remained the dominant asset class at 91.2% of the portfolio (up from 95.6% in 2020), while equity and other investments increased to 6.4% (from 3.7%).
• Income Fluctuations: Total investment income rose to $278.6 million, primarily due to a larger asset base. However, "Other income" decreased significantly from $22.5 million to $7.7 million due to lower amendment and miscellaneous fees.
• Expense Management: Net expenses increased to $135.8 million from $117.3 million. This was driven by higher management fees ($36.9 million vs. $32.1 million) and incentive fees ($46.6 million total vs. $32.9 million), partially offset by a decrease in interest expense ($38.8 million vs. $39.4 million) due to lower LIBOR rates.
• Capital Gains: The company recorded net realized gains of $28.9 million in 2021, a significant improvement from a net loss of $2.6 million in 2020.

Guidance, Outlook, and Risks

Management Commentary: Management highlighted a favorable middle-market lending environment characterized by limited capital availability and strong demand. The company continues to focus on direct originations and maintaining a portfolio of floating-rate loans (98.9% of debt investments) with interest rate floors to hedge against inflation.

Capital Resources: The company maintains strong liquidity with $1.19 billion available under its Revolving Credit Facility and $16.0 million in cash. It issued $300 million in 2026 Notes in February 2021 to extend its debt maturity profile.

Risks and Contingencies:

• LIBOR Transition: The company faces uncertainty regarding the transition from LIBOR to alternative reference rates (e.g., SOFR), which may require renegotiating credit agreements and could impact returns.
• Regulatory Constraints: As a BDC, the company is subject to asset coverage requirements (minimum 150%) and diversification rules that may limit capital raising or investment flexibility.
• Valuation Risk: A significant portion of the portfolio (Level 3 assets) is valued using unobservable inputs, introducing subjectivity to fair value determinations.
• Adviser Dependency: The company relies on Sixth Street Specialty Lending Advisers, LLC, which can terminate the agreement with 60 days' notice.

Investor Verification Checklist

• Verify the impact of the LIBOR transition on the company's floating-rate loan portfolio and debt obligations.
• Review the specific terms of the $332.1 million in unfunded portfolio commitments and their potential drawdown timing.
• Assess the sustainability of the 10.0% weighted average yield given potential prepayment risks and interest rate floors.
• Confirm the status of the co-investment exemptive order with the SEC, which allows the company to co-invest with affiliates.
• Monitor the company's ability to maintain RIC status and the associated 4% excise tax liability on retained income.
