Calculation of Assets Under Management References to total assets under management or AUM represent assets managed by Oaktree and a proportionate amount of the AUM reported by DoubleLine Capital LP ( DoubleLine Capital ), in which Oaktree owns a 20% minority interest. Oaktree's methodology for calculating AUM includes (i) the net asset value (“NAV”) of assets managed directly by Oaktree, (ii) the leverage on which management fees are charged, (iii) undrawn capital that Oaktree is entitled to call from investors in Oaktree funds pursuant to their capital commitments, (iv) for collateralized loan obligation vehicles ( CLOs ), the aggregate par value of collateral assets and principal cash, (v) for publicly-traded business development companies, gross assets (including assets acquired with leverage), net of cash, and (vi) Oaktree's pro rata portion (20%) of the AUM reported by DoubleLine Capital. This calculation of AUM is not based on the definitions of AUM that may be set forth in agreements governing the investment funds, vehicles or accounts managed and is not calculated pursuant to regulatory definitions. Unless otherwise indicated, data provided herein are dated as of June 30, 2023. 1

Non-GAAP Disclosures The OCSI Merger and the OSI2 Merger (the “Mergers”) were accounted for as asset acquisitions in accordance with the asset acquisition method of accounting as detailed in ASC 805-50, Business Combinations—Related Issues ( ASC 805 ). The consideration paid to each of the stockholders of Oaktree Strategic Income Corporation (“OCSI”) and OSI2 were allocated to the individual assets acquired and liabilities assumed based on the relative fair values of the net identifiable assets acquired other than non-qualifying assets, which established a new cost basis for the acquired investments under ASC 805 that, in aggregate, was different than the historical cost basis of the acquired investments prior to the OCSI Merger or OSI2 Merger, as applicable. Additionally, immediately following the completion of the Mergers, the acquired investments were marked to their respective fair values under ASC 820, Fair Value Measurements, which resulted in unrealized appreciation / depreciation. The new cost basis established by ASC 805 on debt investments acquired will accrete / amortize over the life of each respective debt investment through interest income, with a corresponding adjustment recorded to unrealized appreciation / depreciation on such investment acquired through its ultimate disposition. The new cost basis established by ASC 805 on equity investments acquired will not accrete / amortize over the life of such investments through interest income and, assuming no subsequent change to the fair value of the equity investments acquired and disposition of such equity investments at fair value, the Company will recognize a realized gain / loss with a corresponding reversal of the unrealized appreciation / depreciation on disposition of such equity investments acquired. The Company’s management uses the non-GAAP financial measures described above internally to analyze and evaluate financial results and performance and to compare its financial results with those of other business development companies that have not adjusted the cost basis of certain investments pursuant to ASC 805. The Company’s management believes Adjusted Total Investment Income , Adjusted Total Investment Income Per Share , Adjusted Net Investment Income and Adjusted Net Investment Income Per Share are useful to investors as an additional tool to evaluate ongoing results and trends for the Company without giving effect to the accretion income resulting from the new cost basis of the investments acquired in the Mergers because these amounts do not impact the fees payable to Oaktree under its second amended and restated investment advisory agreement (the “A&R Advisory Agreement”), and specifically as its relates to Adjusted Net Investment Income and Adjusted Net Investment Income Per Share , without giving effect to Part II incentive fees. In addition, the Company’s management believes that “Adjusted Net Realized and Unrealized Gains (Losses), Net of Taxes”, “Adjusted Net Realized and Unrealized Gains (Losses), Net of Taxes Per Share”, “Adjusted Earnings (Loss)” and “Adjusted Earnings (Loss) Per Share” are useful to investors as they exclude the non-cash income/gain resulting from the Mergers and used by management to evaluate the economic earnings of its investment portfolio. Moreover, these metrics align the Company's key financial measures with the calculation of incentive fees payable to Oaktree under with the A&R Advisory Agreement (i.e., excluding amounts resulting solely from the lower cost basis of the acquired investments established by ASC 805 that would have been to the benefit of Oaktree absent such exclusion). 18
