Oaktree Specialty Lending Corporation Announces Second Fiscal Quarter 2025 Financial

Results

LOS ANGELES, CA, May 1, 2025 - Oaktree Specialty Lending Corporation (NASDAQ: OCSL) (“Oaktree Specialty Lending” or the “Company”), a specialty finance company, today announced its financial results for the fiscal quarter ended March 31, 2025.

Financial Highlights for the Quarter Ended March 31, 2025

Total investment income was $77.6 million ($0.90 per share) for the second fiscal quarter of 2025, as compared<br>with $86.6 million ($1.05 per share) for the first fiscal quarter of 2025. Adjusted total investment income was $77.2 million ($0.90 per share) for the second fiscal quarter of 2025, as compared with $87.1 million ($1.06 per share)<br>for the first fiscal quarter of 2025. The decrease was driven by lower interest income, which was primarily attributable to a smaller average investment portfolio, the impact of certain investments that were placed on<br>non-accrual status and decreases in reference rates.
GAAP net investment income was $39.1 million ($0.45 per share) for the second fiscal quarter of 2025, as<br>compared with $44.3 million ($0.54 per share) for the first fiscal quarter of 2025. The decrease for the quarter was primarily driven by lower total investment income, partially offset by lower interest expense and income-based (“Part<br>I”) incentive fees (net of fees waived).
--- ---
Adjusted net investment income was $38.7 million ($0.45 per share) for the second fiscal quarter<br>of 2025, as compared with $44.7 million ($0.54 per share) for the first fiscal quarter of 2025. The decrease for the quarter was primarily driven by lower adjusted total investment income, partially offset by lower interest expense and lower<br>Part I incentive fees (net of fees waived).
--- ---
Net asset value (“NAV”) per share was $16.75 as of March 31, 2025, down as compared with $17.63 as of<br>December 31, 2024. The decline from December 31, 2024 primarily reflected losses on certain debt and equity investments.
--- ---
Originated $407.0 million of new investment commitments and received $279.4 million of proceeds from<br>prepayments, exits, other paydowns and sales during the quarter ended March 31, 2025. The weighted average yield on new debt investments was 9.5%.
--- ---
Total debt outstanding was $1,470.0 million as of March 31, 2025. The total debt to equity ratio was<br>1.00x, and the net debt to equity ratio was 0.93x, after adjusting for cash and cash equivalents.
--- ---
Oaktree Capital I, L.P. purchased $100.0 million of shares of OCSL common stock on<br>February 3, 2025 at the Company’s net asset value as of January 31, 2025, which was $17.63 per share and represented a 10% premium to the closing stock price.
--- ---
The Company issued $300 million of unsecured notes during the quarter ended March 31, 2025<br>that mature on February 27, 2030 and bear interest at a rate of 6.340%. In connection with the issuance of the 2030 Notes, the Company entered into an interest rate swap agreement under which the Company receives a fixed interest rate of 6.340%<br>and pays a floating interest rate of the three-month SOFR plus 2.192% on a notional amount of $300.0 million. Additionally, the Company repaid $300 million of unsecured notes that matured on February 25, 2025.
--- ---
Liquidity as of March 31, 2025 was composed of $97.8 million of unrestricted cash and cash equivalents and<br>over $1.0 billion of undrawn capacity under the Company’s credit facilities (subject to borrowing base and other limitations). Unfunded investment commitments were $299.8 million, or $272.6 million excluding unfunded commitments<br>to the Company’s joint ventures. Of the $272.6 million, approximately $252.0 million can be drawn immediately with the remaining amount subject to certain milestones that must be met by portfolio companies or other restrictions.<br>
--- ---
A quarterly and supplemental cash distribution was declared of $0.40 per share and $0.02 per share, respectively,<br>payable in cash on June 30, 2025 to stockholders of record on June 16, 2025.

“Certain challenged portfolio company investments weighed on our results in the second quarter. We are focused on resolving these issues while also positioning our portfolio to deliver more consistent performance going forward,” stated Armen Panossian, Chief Executive Officer and Co-Chief Investment Officer.

“We are focused on further diversifying our portfolio by selectively investing in companies we believe are well positioned to deliver attractive returns given overall market uncertainty caused by tariffs, inflation and high interest rates. Historically, in periods of market volatility, our firm-wide DNA has enabled us to capitalize on opportunities while others are sidelined, and we have ample dry powder for new investments.”

Distribution Declaration

The Board of Directors declared a quarterly distribution of $0.40 per share, payable in cash on June 30, 2025 to stockholders of record on June 16, 2025. The Board of Directors also declared a supplemental distribution of $0.02 per share, payable in cash on June 30, 2025 to stockholders of record on June 16, 2025.

Distributions are paid primarily from distributable (taxable) income. To the extent taxable earnings for a fiscal taxable year fall below the total amount of distributions for that fiscal year, a portion of those distributions may be deemed a return of capital to the Company’s stockholders.

^1^See Non-GAAP Financial Measures below for a description of the non-GAAP measures and the reconciliations from the most comparable GAAP financial measures to the Company’s non-GAAP measures, including on a per share basis. The Company’s management uses these non-GAAP financial measures internally to analyze and evaluate financial results and performance and believes that these non-GAAP financial measures are useful to investors as an additional tool to evaluate ongoing results and trends for the Company and to review the Company’s performance without giving effect to non-cash income/gain/loss resulting from the merger of Oaktree Strategic Income Corporation (“OCSI”) with and into the Company in March 2021 (the “OCSI Merger”) and the merger of Oaktree Strategic Income II, Inc. (“OSI2”) with and into the Company in January 2023 (the “OSI2 Merger”) and, in the case of adjusted net investment income, without giving effect to capital gains incentive fees. The presentation of non-GAAP measures is not intended to be a substitute for financial results prepared in accordance with GAAP and should not be considered in isolation.

The $9.9 million quarterly decline in adjusted total investment income was primarily due to a $9.9 million decrease in interest income, which was primarily attributable to a smaller average investment portfolio, the impact of certain investments that were placed on non-accrual status and decreases in reference rates.

Net expenses for the quarter ended March 31, 2025 totaled $38.2 million, down $3.8 million from the quarter ended December 31, 2024.

and Glick JV. This compared to 81.8% of first lien loans, 3.0% of second lien loans and 9.6% of unsecured debt investments, including the debt investments in SLF JV I and Glick JV, as of December 31, 2024.

As of December 31, 2024, there were nine investments on non-accrual status, which represented 5.1% and 3.9% of the debt portfolio at cost and fair value, respectively.

SLF JV I

The Company’s investments in SLF JV I totaled $128.6 million at fair value as of March 31, 2025, down 5.0% from $135.4 million as of December 31, 2024. The decrease was primarily driven by SLF JV I’s use of leverage and unrealized depreciation in the underlying investment portfolio.

As of March 31, 2025, SLF JV I had $374.7 million in assets, including senior secured loans to 52 portfolio companies. This compared to $344.9 million in assets, including senior secured loans to 42 portfolio companies, as of December 31, 2024. SLF JV I generated cash interest income of $3.2 million for the Company during the quarter ended March 31, 2025, down from $3.4 million in the prior quarter. In addition, SLF JV I generated dividend income of $0.7 million for the Company during the quarter ended March 31, 2025, flat from the prior quarter. As of March 31, 2025, SLF JV I had $73.0 million of undrawn capacity (subject to borrowing base and other limitations) on its $270 million senior revolving credit facility, and its debt to equity ratio was 1.3x.

Glick JV

The Company’s investments in Glick JV totaled $47.3 million at fair value as of March 31, 2025, down 4.6% from $49.6 million as of December 31, 2024. The decrease was primarily driven by Glick JV’s use of leverage and unrealized depreciation in the underlying investment portfolio.

As of March 31, 2025, Glick JV had $125.1 million in assets, including senior secured loans to 41 portfolio companies. This compared to $127.9 million in assets, including senior secured loans to 39 portfolio companies, as of December 31, 2024. Glick JV generated cash interest income of $1.3 million for the Company during the quarter ended March 31, 2025, down from $1.4 million in the prior quarter. As of March 31, 2025, Glick JV had $31.0 million of undrawn capacity (subject to borrowing base and other limitations) on its $100 million senior revolving credit facility, and its debt to equity ratio was 1.3x.

Liquidity and Capital Resources

As of March 31, 2025, the Company had total principal value of debt outstanding of $1,470.0 million, including $520.0 million of outstanding borrowings under its revolving credit facilities, $350.0 million of the 2.700% Notes due 2027, $300.0 million of the 7.100% Notes due 2029 and $300.0 million of the 6.340% Notes due 2030. The funding mix was composed of 35% secured and 65% unsecured borrowings as of March 31, 2025. The Company was in compliance with all financial covenants under its credit facilities as of March 31, 2025.

As of March 31, 2025, the Company had $97.8 million of unrestricted cash and cash equivalents and over $1.0 billion of undrawn capacity on its credit facilities (subject to borrowing base and other limitations). As of March 31, 2025, unfunded investment commitments were $299.8 million, or $272.6 million excluding unfunded commitments to the Company’s joint ventures. Of the $272.6 million, approximately $252.0 million could be drawn immediately with the remaining amount subject to certain milestones that must be met by portfolio companies or other restrictions. The Company has analyzed cash and cash equivalents, availability under its credit facilities, the ability to rotate out of certain assets and amounts of unfunded commitments that could be drawn and believes its liquidity and capital resources are sufficient to invest in market opportunities as they arise.

As of March 31, 2025, the weighted average interest rate on debt outstanding, including the effect of the interest rate swap agreements was 6.7%, up from 6.2% as of December 31, 2024, primarily driven by the impact of the repayment of the 3.500% Notes due 2025 and the issuance of the 6.340% Notes due 2030.

The Company’s total debt to equity ratio was 1.00x and 1.11x as of each of March 31, 2025 and December 31, 2024, respectively. The Company’s net debt to equity ratio was 0.93x and 1.03x as of each of March 31, 2025 and December 31, 2024, respectively.

Non-GAAP Financial Measures

On a supplemental basis, the Company is disclosing certain adjusted financial measures, each of which is calculated and presented on a basis of methodology other than in accordance with GAAP (“non-GAAP”). The Company’s management uses these non-GAAP financial measures internally to analyze and evaluate financial results and performance and believes that these non-GAAP financial measures are useful to investors as an additional tool to evaluate ongoing results and trends for the Company and to review the Company’s performance without giving effect to non-cash income/gain/loss resulting from the OCSI Merger and the OSI2 Merger and in the case of adjusted net investment income, without giving effect to capital gains incentive fees. The presentation of the below non-GAAP measures is not intended to be a substitute for financial results prepared in accordance with GAAP and should not be considered in isolation.

“Adjusted Total Investment Income” and “Adjusted Total Investment Income Per Share” –****represents total investment income excluding any amortization or accretion of interest income resulting solely from the cost basis established by ASC 805 (see below) for the assets acquired in connection with the OCSI Merger and the OSI2 Merger.<br>
“Adjusted Net Investment Income” and “Adjusted Net Investment Income Per Share” –<br>represents net investment income, excluding (i) any amortization or accretion of interest income resulting solely from the cost basis established by ASC 805 (see below) for the assets acquired in connection with the OCSI Merger and the OSI2<br>Merger and (ii) capital gains incentive fees (“Part II incentive fees”).
--- ---
“Adjusted Net Realized and Unrealized Gains (Losses), Net of Taxes” and “Adjusted Net Realized andUnrealized Gains (Losses), Net of Taxes Per Share” – represents net realized and unrealized gains (losses) net of taxes excluding any net realized and unrealized gains (losses) resulting solely from the cost basis established by ASC<br>805 (see below) for the assets acquired in connection with the OCSI Merger and the OSI2 Merger.
--- ---
“Adjusted Earnings (Loss)” and “Adjusted Earnings (Loss) Per Share” – represents the sum of<br>(i) Adjusted Net Investment Income and (ii) Adjusted Net Realized and Unrealized Gains (Losses), Net of Taxes and includes the impact of Part II incentive fees^1^, if any.<br>
--- ---

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 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 the 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 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 Fund Advisors, LLC (the “Adviser”) under its investment advisory agreement (as amended and restated from time to time, 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 and gain/loss resulting from the Mergers and are used by management to evaluate the economic earnings of its

^1^ Adjusted earnings (loss) includes accrued Part II incentive fees. As of and for the three months ended December 31, 2024, there was no accrued Part II incentive fee liability. Part II incentive fees are contractually calculated and paid at the end of the fiscal year in accordance with the A&R Advisory Agreement, which differs from Part II incentive fees accrued under GAAP. For the three months ended December 31, 2024, no amounts were payable under the A&R Advisory Agreement.

investment portfolio. Moreover, these metrics more closely align the Company’s key financial measures with the calculation of incentive fees payable to the Adviser 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 the Adviser absent such exclusion).

Forward Looking Statements & Legal Disclosures Second Quarter 2025 Investor Presentation NASDAQ: OCSL Some of the statements in this presentation constitute forward-looking statements because they relate to future events or our future performance or financial condition. The forward-looking statements contained in this presentation may include statements as to: our future operating results and distribution projections; the ability of Oaktree Fund Advisors, LLC (together with its affiliates, “Oaktree”) to implement Oaktree’s future plans with respect to our business; the ability of Oaktree and its affiliates to attract and retain highly talented professionals; our business prospects and the prospects of our portfolio companies; the impact of the investments that we expect to make; the ability of our portfolio companies to achieve their objectives; our expected financings and investments and additional leverage we may seek to incur in the future; the adequacy of our cash resources and working capital; the timing of cash flows, if any, from the operations of our portfolio companies; the cost or potential outcome of any litigation to which we may be a party; and the impact of current global economic conditions, including those caused by inflation, an elevated (but decreasing) interest rate environment and geopolitical risks on all of the foregoing. In addition, words such as “anticipate,” “believe,” “expect,” “seek,” “plan,” “should,” “estimate,” “project” and “intend” indicate forward-looking statements, although not all forward-looking statements include these words. The forward-looking statements contained in this presentation involve risks and uncertainties. Our actual results could differ materiallyfrom those implied or expressed in the forward-looking statements for any reason, including the factors set forth in “Risk Factors” and elsewhere in our annual report on Form 10-K for the fiscal year ended September 30, 2024 and our quarterly report on Form 10-Q for the quarter ended December 31, 2024. Other factors that could cause actual results to differ materially include: changes or potential disruptions in our operations, the economy, financial markets and political environment, including those caused by tariffs and trade disputes with other countries, inflation and an elevated interest rate environment; risks associated with possible disruption in our operations or the economy generally due to terrorism, war or other geopolitical conflict, natural disasters, pandemics or cybersecurity incidents; future changes in laws or regulations (includingthe interpretation of these laws and regulations by regulatory authorities); conditions in our operating areas, particularly with respect to business development companies or regulated investment companies; and otherconsiderations disclosed from time to time in our publicly disseminated documents and filings.

Calculation of Assets Under Management References to total “assets under management” or “AUM” represent assets managed by Oaktree and a proportionate amount of the AUMreported 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 March 31, 2025.

2 Strategic Actions In Support of OCSL Oaktree remains committed to the long-term growth and success of OCSLEquity Raise •On February 3, Oaktree purchased $100 million of newly issued shares of OCSL common stock at a price of $17.63/share equal to net asset value per share on January 31, 2025 •This transaction represented a 10% premium to the closing stock price on January 31, 2025, and resulted in a nearly 7% increase in net assets at the time of share issuance •The equity raise (coupled with additional leverage) increased dry powder for deployment, enabling growth and further diversification of the portfolio New Incentive Fee Cap •In the first fiscal quarter of 2025, Oaktree instituted an incentive fee cap (i.e., a total return hurdle). In the second fiscal quarter, this resulted in a waiver of $6.7 million of Part I incentive fees •This new arrangement includes a lookback provision that commences October 1, 2024, building to a rolling 12 quarter lookback by the Company’s 2027 fiscal year-end Although we have voluntarily waived fees in previous quarters, this formalizes our process and provides clarity

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 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). 17
