QUARTER ENDED MARCH 31, 2026

FY 2026 Q2 Earnings Review (Quarter Ended 03/31/2026)

Earnings Summary

Net investment income remained solid, though impacted by sector headwinds (i.e., delayed impact of CQ4 2025 interest rate cuts)

Adjusted net investment income per share of $0.34, or an annualized adjusted NII ROE of 9.5%1,2

Earnings per share impacted by market-driven credit spread widening and associated fair value adjustments

Net income per share of ($0.18) driven by ($0.51) per share of net unrealized losses on investments, primarily resulting from fair value markdowns in GBDC's highest performing portfolio companies and to a lesser extent additional fair value adjustments on GBDC's small tail of underperforming borrowers (see pg. 8)

Key net investment income profitability drivers:

Continued solid portfolio company performance

Stable current portfolio spreads, but delayed impact of calendar Q4 2025 interest rate cuts

Attractive and falling borrowing costs

Leading fee structure with (i) base management fee of 1.0%, and (ii) incentive fee rate of 15.0% (8.0% hurdle rate), and prudent operating expense management

Portfolio & Credit Quality

Continued strong portfolio company performance with ~89% of the total investment portfolio having internal performance ratings of '4' or '5'3

Non-accrual investments increased but still low at 1.4% of total investments at fair value (2.3% at cost)

Diversified and healthy software portfolio of first lien senior secured middle market loans, underpinned by Golub Capital's 20+ year track record of lending to technology and software portfolio companies
