StockStory’s Take

Sixth Street Specialty Lending’s fourth quarter was marked by a revenue decline year over year, despite results that came in above Wall Street’s expectations. The market reacted negatively, with management pointing to persistent pressure on loan spreads and increased competition in direct lending as key challenges. CEO Bo Stanley emphasized the impact of idiosyncratic credit events and unrealized losses, notably highlighting, “credit outcomes are always idiosyncratic.” The team also noted substantial repayment activity and a focus on maintaining disciplined credit selection amid tightening market conditions.

Looking forward, management expects the investment environment in 2026 to remain highly competitive, with sustained tight spreads and ongoing capital reallocation in the private credit sector. CEO Bo Stanley highlighted the firm’s approach to leveraging periods of volatility, stating, “Periods of market volatility and uncertainty play to our strength.” The company is counting on its robust liquidity, increased investment capacity, and the formation of its new joint venture—Structured Credit Partners—to support earnings and provide flexibility as capital continues to shift within the industry. Management remains focused on thematic investing, seeking opportunities in businesses with durable competitive advantages, especially those benefiting from shifts in technology such as artificial intelligence.

Key Insights from Management’s Remarks

Management attributed the quarter’s performance to elevated repayment activity, margin pressure from tight spreads, and selective deployment of capital during uncertain market conditions.

• Repayment-driven fee income: High levels of repayment activity contributed to a significant increase in activity-based fee income, with portfolio turnover reaching 34%, well above historical averages. This was mainly driven by refinancing, which created both realized gains and the opportunity for selective reinvestment at attractive risk-adjusted returns.

• Selective credit deployment: Management continued to emphasize disciplined underwriting, focusing on businesses with robust unit economics and resilient end markets. The majority of new investments in the quarter were first lien loans, underscoring a conservative approach to risk.

• Shifting software exposure: The team noted a marginal reduction in software-related investments due to declining unit economics and increased competition in private credit markets for software deals. Instead, capital was rotated toward businesses with stronger moats and defensible positions.

• Portfolio resilience: Despite lower equity valuations in the market, core portfolio companies maintained stable leverage ratios and demonstrated revenue and EBITDA growth rates of 9% and 12%, respectively, supporting the view that the underlying credit quality remained robust.

• Structured Credit Partners joint venture: The announcement of the SCP joint venture with Carlyle aims to diversify earnings and provide access to CLO equity returns without management fees, which management believes will be accretive to overall earnings in the mid-teens percent range.

Drivers of Future Performance

Management expects continued competition and sector rebalancing, with earnings supported by prudent asset selection and new investment initiatives.

• Competitive lending landscape: The company sees ongoing tight spreads and high competition in private direct lending, which may constrain the ability to grow yields in the near term. Management believes stability in spreads is likely, though they acknowledge this could change if capital outflows accelerate across the sector.

• Emphasis on thematic investing: As capital rotates within private credit, management’s focus remains on identifying businesses with strong competitive advantages, especially those that can withstand technological disruption. They expect the winners in sectors like enterprise software will be those with resilient customer relationships and data moats.

• Earnings impact from joint venture: The new Structured Credit Partners JV is intended to add a diversified source of earnings by investing in broadly syndicated loan CLO equity. Management expects this to provide mid-teens returns on invested capital, supporting long-term adjusted net investment income targets.
