Strategic Initiatives
Growth programs, investments, and their expected impact
Proactively managing the balance sheet by extending the revolving credit facility maturity to 2031 and issuing $300 million of fixed-rate unsecured notes to pay down floating-rate secured debt.
Expected impact: Reduces refinancing risk, shifts the funding mix toward unsecured debt (~68% unsecured post-issuance), and locks in long-term stable capital amid interest rate volatility.
Resetting the quarterly base dividend to $0.42 per share to align distributions with current net investment income and target a sustainable 10% to 10.5% ROE.
Expected impact: Protects net asset value (NAV) by preventing over-distribution of earnings, ensuring long-term capital preservation and dividend sustainability.
Securing shareholder authorization to issue up to 25% of outstanding common stock below NAV to maintain liquidity and capture high-yield lending opportunities during market dislocations.
Expected impact: Enhances financial agility and funding options, allowing the BDC to play offense when competitors are forced to play defense, despite potential short-term share dilution.
