Capital Southwest's Strategic Debt Refinancing and Capital Allocation: A Prudent Path to Sustainable Growth

In the ever-evolving landscape of leveraged finance, Capital Southwest Corporation (CSWC) has emerged as a model of disciplined capital management. The company's recent $350 million debt refinancing, announced in September 2025, underscores its commitment to optimizing capital structure while mitigating risk—a strategy that could serve as a blueprint for other business development companies (BDCs). By issuing 5.95% notes due 2030 at a yield-to-maturity of 6.104%, CSWC has effectively replaced higher-cost debt, including its 7.75% notes due 2028 and 3.375% notes due 2026Capital Southwest Corporation Prices $350 Million Public Offering of 5.950% Notes Due 2030^[1].

This structural advantage reduces the immediate pressure of refinancing and insulates the company from near-term volatility in credit markets. Moreover, the expansion of its corporate credit facility to $510 million and the $42 million in equity proceeds raised through its ATM program further bolster liquidity, enabling CSWC to navigate potential economic headwindsCapital Southwest Corporation (CSWC) Stock Price^[4].
