(1) Core investment income represents reported total investment income as determined in accordance with U.S. generally accepted accounting principles, or U.S. GAAP, less the impact of purchase price discount accounting in connection with the Garrison Capital Inc. (“GARS”) and Harvest Capital Credit Corporation (“HCAP”) mergers. Portman Ridge believes presenting core investment income and the related per share amount is useful and appropriate supplemental disclosure for analyzing its financial performance due to the unique circumstance giving rise to the purchase accounting adjustment. However, core investment income is a non-U.S. GAAP measure and should not be considered as a replacement for total investment income and other earnings measures presented in accordance with U.S. GAAP. Instead, core investment income should be reviewed only in connection 3 with such U.S. GAAP measures in analyzing Portman Ridge’s financial performance. (2) Net leverage is calculated as the ratio between (A) debt, excluding unamortized debt issuance costs, less available cash and cash equivalents, and restricted cash and (B) NAV. Portman Ridge believes presenting a net leverage ratio is useful and appropriate supplemental disclosure because it reflects the Company’s financial condition net of $36.6 million and $39.6 million of cash and cash equivalents and restricted cash as of June 30, 2024 and March 31, 2024, respectively. However, the net leverage ratio is a non-U.S. GAAP measure and should not be considered as a replacement for the regulatory asset coverage ratio and other similar information presented in accordance with U.S. GAAP. Instead, the net leverage ratio should be reviewed only in connection with such U.S. GAAP measures in analyzing Portman Ridge’s financial condition.
