Oaktree Specialty Lending Corporation Announces First Fiscal Quarter 2026 Financial Results

LOS ANGELES, CA, February 4, 2026 - Oaktree Specialty Lending Corporation (NASDAQ: OCSL) (“Oaktree Specialty Lending” or the “Company”), a specialty finance company, today announced its financial results for the first quarter ended December 31, 2025.

FinancialHighlights for the Quarter Ended December 31, 2025

Total investment income was $75.1 million ($0.85 per share) for the first fiscal quarter of 2026 as compared<br>to $77.3 million ($0.88 per share) for the fourth fiscal quarter of 2025. Adjusted total investment income was $74.5 million ($0.85 per share) for the first fiscal quarter of 2026 as compared with $76.9 million ($0.87 per share) for<br>the fourth fiscal quarter of 2025. The decrease was driven by lower interest income primarily attributable to lower reference rates and lower original issue discount (“OID”) acceleration, partially offset by higher fee income primarily<br>attributable to higher prepayment and exit fees.
GAAP net investment income was $36.7 million ($0.42 per share) for the first fiscal quarter of 2026 as<br>compared with $35.8 million ($0.41 per share) for the fourth fiscal quarter of 2025. The increase for the quarter was primarily driven by lower net expenses due to lower income-based (“Part I”) incentive fees (net of fees waived),<br>offset by lower total investment income and higher interest expense.
--- ---
Adjusted net investment income was $36.1 million ($0.41 per share) for the first fiscal<br>quarter of 2026 as compared with $35.4 million ($0.40 per share) for the fourth fiscal quarter of 2025. The increase for the quarter was primarily driven by lower net expenses due to lower Part I incentive fees (net of fees waived), offset by<br>lower total investment income and higher interest expense.
--- ---
Net asset value (“NAV”) per share was $16.30 as of December 31, 2025, down as compared with<br>$16.64 as of September 30, 2025. The decrease from September 30, 2025 was primarily driven by unrealized depreciation on certain debt and equity investments.
--- ---
Originated $316.6 million of new investment commitments and received $178.5 million of proceeds from<br>prepayments, exits, other paydowns and sales during the quarter ended December 31, 2025. The weighted average yield on new debt investments was 8.7%.
--- ---
Total debt outstanding was $1,615.0 million as of December 31, 2025. The total debt to equity ratio was<br>1.12x, and the net debt to equity ratio was 1.07x, after adjusting for cash and cash equivalents.
--- ---
Liquidity as of December 31, 2025 was composed of $80.8 million of unrestricted cash and cash<br>equivalents and $495.0 million of undrawn capacity under the Company’s credit facility (subject to borrowing base and other limitations). Unfunded investment commitments were $274.5 million, or $247.3 million excluding unfunded<br>commitments to the Company’s joint ventures.
--- ---
A quarterly cash distribution was declared of $0.40 per share payable in cash on March 31, 2026 to<br>stockholders of record on March 16, 2026.
--- ---

“We delivered solid results in the first fiscal quarter of 2026 including adjusted net investment income of $36.7 million, or $0.41 per share, and fully covered our dividend,” said Armen Panossian, Chief Executive Officer and Chief Investment Officer of Oaktree Specialty Lending. “We also made continued progress in stabilizing our investment portfolio and are optimistic that we will see continued progress in the coming quarters. New deployments for the quarter were strong at $317 million. Looking ahead, we will continue to evaluate levers to help offset lower base rates and support net investment income.”

Distribution Declaration

The Board of Directors declared a quarterly distribution of $0.40 per share, payable in cash on March 31, 2026 to stockholders of record on March 16, 2026.

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.

Adjusted total investment income for the quarter ended December 31, 2025 was $74.5 million and included $66.3 million of interest income from portfolio investments, $3.8 million of PIK interest income, $3.0 million of fee income and $1.4 million of dividend income. The $2.4 million quarterly decrease in adjusted total investment income was primarily attributable to lower reference rates and lower OID acceleration, partially offset by higher fee income primarily attributable to higher prepayment and exit fees.

Net expenses for the quarter ended December 31, 2025 totaled $38.4 million, down $2.9 million from the quarter ended September 30, 2025. The decrease for the quarter was primarily driven by $4.0 million of lower Part I incentive fees (net of fees waived), partially offset by higher interest expense due to higher borrowings outstanding offset by lower reference rates.

Adjusted net investment income was $36.1 million ($0.41 per share) for the quarter ended December 31, 2025, which was up from $35.4 million ($0.40 per share) for the quarter ended September 30, 2025. The increase of $0.7 million primarily

reflected $2.9 million of lower net expenses, offset by $2.4 million of lower adjusted total investment income and higher interest expense.

Adjusted net realized and unrealized losses, net of taxes, were $30.4 million for the quarter ended December 31, 2025, primarily reflecting unrealized losses on certain debt and equity investments.

As of December 31, 2025, 95.4% of the Company’s portfolio at fair value consisted of debt investments, including 84.8% of first lien loans, 1.6% of second lien loans and 9.0% of unsecured debt investments, including the debt investments in SLF

JV I and Glick JV. This compared to 83.5% of first lien loans, 2.4% of second lien loans and 8.7% of unsecured debt investments, including the debt investments in SLF JV I and Glick JV, as of September 30, 2025.

As of December 31, 2025, there were eleven investments on non-accrual status, which represented 6.5% and 3.1% of the debt portfolio at cost and fair value, respectively. As of September 30, 2025, there were ten investments on non-accrual status, which represented 6.5% and 3.0% of the debt portfolio at cost and fair value, respectively.

SLF JV I

The Company’s investments in SLF JV I totaled $120.9 million at fair value as of December 31, 2025, down 3.0% from $124.6 million as of September 30, 2025. The decrease was primarily driven by SLF JV I’s use of leverage and unrealized losses in the underlying investment portfolio.

As of December 31, 2025, SLF JV I had $410.0 million in assets, including senior secured loans to 74 portfolio companies. This compared to $447.4 million in assets, including senior secured loans to 72 portfolio companies, as of September 30, 2025. SLF JV I generated cash interest income of $3.2 million for the Company during the quarter ended December 31, 2025, down slightly from $3.3 million in the prior quarter. In addition, SLF JV I generated dividend income of $0.5 million for the Company during the quarter ended December 31, 2025, flat from prior quarter. As of December 31, 2025, SLF JV I had $18.5 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 1.8x.

Glick JV

The Company’s investments in Glick JV totaled $43.9 million at fair value as of December 31, 2025, down 4.6% from $46.1 million as of September 30, 2025. The decrease was primarily driven by Glick JV’s use of leverage and realized losses in the underlying investment portfolio.

As of December 31, 2025, Glick JV had $191.6 million in assets, including senior secured loans to 115 portfolio companies. This compared to $149.1 million in assets, including senior secured loans to 57 portfolio companies, as of September 30, 2025. Glick JV generated cash interest income of $1.3 million for the Company during the quarter ended December 31, 2025, flat from the prior quarter.

Liquidity and Capital Resources

As of December 31, 2025, the Company had total principal value of debt outstanding of $1,615.0 million, including $665.0 million of outstanding borrowings under its revolving credit facility and $950.0 million of unsecured notes payable. The funding mix was composed of 41% secured and 59% unsecured borrowings as of December 31, 2025. The Company was in compliance with all financial covenants under its syndicated credit facility as of December 31, 2025.

As of December 31, 2025, the Company had $80.8 million of unrestricted cash and cash equivalents and $495.0 million of undrawn capacity on its credit facility (subject to borrowing base and other limitations). As of December 31, 2025, unfunded investment commitments were $274.5 million, or $247.3 million excluding unfunded commitments to the Company’s joint ventures. 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 December 31, 2025, the weighted average interest rate on debt outstanding, including the effect of the interest rate swap agreements was 6.1%, down from 6.5% as of September 30, 2025, primarily driven by lower reference rates.

The Company’s total debt to equity ratio was 1.12x and 1.02x as of December 31, 2025 and September 30, 2025, respectively. The Company’s net debt to equity ratio was 1.07x and 0.97x as of December 31, 2025 and September 30, 2025, 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<br>the OSI2 Merger.
“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<br>the sum of (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

^1^ Adjusted earnings (loss) includes accrued Part II incentive fees. As of and for the three months ended December 31, 2025, 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, 2025, no Part II incentive fees were payable under the A&R Advisory Agreement.

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 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).

Calculation of Assets Under Management References to total “assets under management” or “AUM” represent assets managed by Oaktree, a proportionate amount of the AUM reported by DoubleLine Capital LP (“DoubleLine Capital”), and other minority corporate investments.

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.

Strategic Actions In Support of OCSL • On February 3, 2025, 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 Equity Raise • 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 • In the first fiscal quarter of 2025, Oaktree implemented an incentive fee cap (i.e., a total return hurdle). Since the implementation of the incentive fee cap, OCSL has retained $25.7 million in Part I incentive fees that would have otherwise been paid to Oaktree. Incentive Fee Cap • This 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 • The incentive fee cap formalized our process and provided clarity Oaktree remains committed to the long-term growth and success of OCSL 17

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 fourth 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
