Per share returns are calculated based on the daily weighted average shares outstanding during the period presented. Due to the significant changes in net assets, net investment income and net income that may occur quarter-to-quarter as a result of Golub Capital BDC 4 Inc. (“we”, “us”, “our”, the “Company” or “GBDC 4”) commencing operations on April 1, 2022, per share amounts may fluctuate significantly from quarter-to-quarter and quarterly comparisons may not be meaningful. 2. As a supplement to U.S. generally accepted accounting principles (“GAAP”) financial measures, the Company has provided this non-GAAP financial measure. The Company believes that this non-GAAP financial measure is useful as it excludes the accrual (reversal) of the capital gain incentive fee under GAAP which is not contractually payable under the terms of the Company’s investment advisory agreement with GC Advisors ( the “Investment Advisory Agreement”). The capital gain incentive fee payable as calculated under the Investment Advisory Agreement for the period ended June 30, 2024 is $0. However, in accordance with GAAP, the Company is required to include aggregate unrealized appreciation on investments in the calculation and accrue a capital gain incentive fee on a quarterly basis as if such unrealized capital appreciation were realized, even though such unrealized capital appreciation is not permitted to be considered in calculating the fee actually payable under the Investment Advisory Agreement. Although this non-GAAP financial measure is intended to enhance investors’ understanding of the Company’s business and performance, this non-GAAP financial measure should not be considered an alternative to GAAP 3. Return on equity calculations are based on daily weighted average of total net assets during the period presented. 4. Quarterly return on equity is calculated as the annualized return on average equity divided by four. Return on equity calculations are based on the daily weighted average of total net assets during the period presented. 5. Junior Debt consists of second lien and subordinated debt.
