(3) Total return based on market value is based upon the change in market price per share between the opening and ending market values per share in the period, adjusted for dividends. Total return based on net asset value is based upon the change in net asset value per share between the opening and ending net asset values per share in the period, adjusted for dividends. (4) Financial highlights for periods of less than one year are annualized and the ratios of operating expenses to average net assets and net investment loss to average net assets are adjusted accordingly. For the three and six months ended June 30, 2026, the annualization of these ratios excludes the effect of approximately $20.0 million of accelerated and non-recurring expenses incurred in connection with the Externalization. Because the ratios are calculated for the Company’s common stock taken as a whole, an individual investor’s ratios may vary from these ratios. 8
