GBDC's shares declined 2.7% following the quarter as investors reacted to mark-to-market fair value write-downs driven by meaningful spread widening, which weighed on NAV despite underlying credit fundamentals remaining stable.

• The quarter showed a small NAV loss of about 1%, mainly due to fair value markdowns caused by spread widening rather than realized credit losses.
• Adjusted net investment income (NII) per share was $0.34, equating to an annualized adjusted NII return on equity of 9.5%.
• Nonaccruals remain low relative to BDC peers, and borrower performance ratings modestly improved quarter-over-quarter.
• The company emphasized that mark-to-market losses are temporary and should reverse as market spreads normalize or credits pay down.
• Management highlighted ongoing headwinds including lower base rates, narrowing spreads, elevated credit stress, and emerging sector-specific concerns (notably AI-related uncertainties).
