Oaktree Specialty Lending Corporation Announces Fourth Fiscal Quarter and Full Year 2023

Financial Results and Declares Quarterly Distribution of $0.55 Per Share and Special

Distribution of $0.07 Per Share

LOS ANGELES, CA, November 14, 2023 - 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 and year ended September 30, 2023.

Financial Highlights for the Quarter and Year Ended September 30, 2023¹

• Total investment income was $101.9 million ($1.32 per share) and $379.3 million ($5.26 per share) for the fourth fiscal quarter and full year, as compared with $101.9 million ($1.32 per share) and $262.5 million ($4.32 per share) for the third fiscal quarter of 2023 and the full year of 2022. Adjusted total investment income was $102.2 million ($1.32 per share) and $376.4 million ($5.22 per share) for fiscal quarter and full year ended September 30, 2023, as compared with $101.1 million ($1.31 per share) and $251.3 million ($4.14 per share) for the third fiscal quarter of 2023 and the full year of 2022. The increase for the quarter was primarily driven by higher original issue discount (“OID”) acceleration from investment repayments, partially offset by lower fee income. The increase for the full year was primarily driven by the impact of higher base rates on the Company’s floating rate debt portfolio and the growth of the investment portfolio from the assets acquired in the merger with Oaktree Strategic Income II, Inc. (“OSI2”) (the “OSI2 Merger”).

• GAAP net investment income was $47.5 million ($0.62 per share) and $180.7 million ($2.51 per share) for the fourth fiscal quarter and full year, as compared with $48.4 million ($0.63 per share) and $148.6 million ($2.45 per share) for the third fiscal quarter of 2023 and full year of 2022. The decrease for the quarter was primarily driven by higher interest expense, partially offset by lower base management fees (net of waivers). The increase for the full year was primarily driven by higher adjusted total investment income, partially offset by higher interest expense, incentive and base management fees, and other operating expenses.

• Adjusted net investment income was $47.8 million ($0.62 per share) and $177.8 million ($2.47 per share) for the fourth fiscal quarter and full year, as compared with $47.6 million ($0.62 per share) and $128.6 million ($2.12 per share) for the third fiscal quarter of 2023 and the full year of 2022. The increase for the full year was primarily driven by higher adjusted total investment income, partially offset by higher interest expense, incentive and base management fees, and other operating expenses.

• Net asset value (“NAV”) per share was $19.63 as of September 30, 2023, up slightly as compared with $19.58 as of June 30, 2023 and down from $20.38 as of September 30, 2022. The increase from June 30, 2023 was mainly the result of undistributed net investment income. The decline from September 30, 2022 primarily reflected credit spread widening on debt investments that drove unrealized losses on certain investments and the impact of the December 2022 special distribution.

• Originated $87.5 million of new investment commitments and received $364.4 million of proceeds from prepayments, exits, other paydowns and sales during the quarter ended September 30, 2023. The weighted average yield on new debt investments was 12.0%.

• Total debt outstanding was $1,660.0 million as of September 30, 2023. The total debt to equity ratio was 1.10x, and the net debt to equity ratio was 1.01x, after adjusting for cash and cash equivalents.

• The Company issued $300 million of unsecured notes during the quarter ended September 30, 2023 that mature on February 15, 2029 and bear interest at a rate of 7.100%. In connection with the issuance of the 2027 Notes, the Company entered into an interest rate swap agreement under which the Company receives a fixed interest rate of 7.100% and pays a floating rate of the three-month SOFR plus 3.1255% on a notional amount of $300 million.

• Liquidity as of September 30, 2023 was composed of $136.5 million of unrestricted cash and cash equivalents and $907.5 million of undrawn capacity under the Company’s credit facilities (subject to borrowing base and other limitations). Unfunded investment commitments were $232.7 million, or $205.6 million excluding unfunded commitments to the Company’s joint ventures. Of the $205.6 million, approximately $154.2 million can be drawn immediately with the remaining amount subject to certain milestones that must be met by portfolio companies or other restrictions.

¹ The Company completed a 1-for-3 reverse stock split on January 20, 2023, effective as of the commencement of trading on January 23, 2023. All share amounts and per share information included in this press release reflect the reverse stock split on a retroactive basis

• A quarterly cash distribution was declared of $0.55 per share. The distribution is payable in cash on December 29, 2023 to stockholders of record on December 15, 2023.

• A special cash distributions was declared of $0.07 per share. The distribution is payable in cash on December 29, 2023 to stockholders of record on December 15, 2023..

Armen Panossian, Chief Executive Officer and Chief Investment Officer, said, “We delivered solid fourth quarter results, culminating a fiscal year defined by strong earnings growth and attractive new deployment activity. We produced record adjusted net investment income for the year, driven by higher base rates that highlighted the power of our predominantly floating rate loan portfolio, as well as our ability to deploy capital at wider spreads. This enabled us to generate an ROE of over 12% for the year.”

“Additionally, our merger with Oaktree Strategic Income II, Inc. contributed to our record results. The transaction, which closed in January and proved accretive to earnings, created greater scale and financial flexibility that we believe will drive continued positive investment performance. We also strengthened our capital structure in August through the issuance of $300 million of notes due 2029, creating additional flexibility and increased investment capacity that positions OCSL to prudently pursue new investment opportunities and favorable returns for our shareholders.”

Distribution Declaration

The Board of Directors declared quarterly and special distributions of $0.55 per share and $0.07 per share, respectively. The distributions are payable in cash on December 29, 2023 to stockholders of record on December 15, 2023.

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.

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 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 September 30, 2023 was $102.2 million and included $95.0 million of interest income from portfolio investments, $5.5 million of payment-in-kind (“PIK”) interest income, $0.6 million of fee income and $1.1 million of dividend income. The $1.1 million sequential increase in adjusted total investment income was attributable to a $2.1 million increase in interest income mainly due to higher OID acceleration from exited investments, partially offset by a $1.0 million decrease in fee income mainly driven by lower commitment and exit fees.

Adjusted total investment income for the full year ended September 30, 2023 was $376.4 million and included $345.9 million of interest income from portfolio investments, $19.8 million of PIK interest income, $6.5 million of fee income and $4.2 million of dividend income. The $125.1 million year-over-year increase was primarily driven by $127.4 million of higher interest income principally due to the growth in the size of the investment portfolio following the merger with OSI2 as well as the impact of higher base rates on the Company’s floating rate debt portfolio. This was partially offset by $2.2 million of lower dividend income.

Net expenses for the quarter ended September 30, 2023 totaled $54.4 million, up $0.9 million from the quarter ended June 30, 2023. The increase in net expenses was primarily driven by $1.5 million of higher interest expense due to the impact of rising interest rates on the Company’s floating rate liabilities. This was partially offset by a $0.5 million decrease in base management fees during the quarter due to a decrease in the size of the investment portfolio.

Net expenses for full-year ended September 30, 2023 totaled $198.5 million, up $87.9 million from the year ended September 30, 2022. The increase was primarily driven by $64.7 million of higher interest expense due to the impact of rising interest rates on the Company’s floating rate liabilities and an increase in average borrowings outstanding. Further contributing to the increase were $9.2 million of higher part I incentive fees as a result of higher adjusted net investment income during the year, an $8.8 million reversal of previously accrued capital gains incentive fees in the prior year, $2.8 million of higher management fees (net of waivers) as a result of a larger investment portfolio and a $2.4 million increase professional fees and general and administrative expenses during the year.

Adjusted net investment income was $47.8 million ($0.62 per share) for the quarter ended September 30, 2023, up slightly from $47.6 million ($0.62 per share) for the quarter ended June 30, 2023. The increase of $0.2 million primarily reflected $1.1 million of higher adjusted total investment income, partially offset by $0.9 million of higher net expenses.

Adjusted net investment income was $177.8 million ($2.47 per share) for the full year 2023, up from $128.6 million ($2.12 per share) for the year ended September 30, 2022. The increase of $49.2 million primarily reflected $125.1 million of higher adjusted total investment income and a $3.3 million decrease in the provision for income taxes on net investment income, partially offset by $64.7 million of higher interest expense, $9.2 million of higher part I incentive fees, $2.8 million of higher management fees (net of waivers) and a $2.4 million increase in professional fees and general and administrative expenses during the year.

Adjusted net realized and unrealized losses, net of taxes, was $1.7 million for the quarter ended September 30, 2023, primarily reflecting the impact of the provision for income taxes. Adjusted net realized and unrealized losses, net of taxes, was $40.2 million for the year ended September 30, 2023, primarily reflecting realized and unrealized losses on certain debt and equity investments.

The Company’s investments in SLF JV I totaled $141.5 million at fair value as of September 30, 2023, up 1% from $140.6 million as of June 30, 2023. The increase was primarily driven by SLF JV I’s use of leverage and unrealized appreciation in the underlying investment portfolio.

The Company’s investments in Glick JV totaled $50.0 million at fair value as of September 30, 2023, up 1% from $49.6 million as of June 30, 2023. The increase was primarily driven by Glick JV I’s use of leverage and unrealized appreciation in the underlying investment portfolio.

As of September 30, 2023, Glick JV had $141.2 million in assets, including senior secured loans to 38 portfolio companies. This compared to $126.8 million in assets, including senior secured loans to 37 portfolio companies, as of June 30, 2023. As of September 30, 2023, no investments held by Glick JV were on non-accrual status.

Liquidity and Capital Resources

As of September 30, 2023, the Company had total principal value of debt outstanding of $1,660.0 million, including $710.0 million of outstanding borrowings under its revolving credit facilities, $300.0 million of the 3.500% Notes due 2025, $350.0 million of the 2.700% Notes due 2027 and $300.0 million of the 7.100% Notes due 2029. The funding mix was composed of 43% secured and 57% unsecured borrowings as of September 30, 2023. The Company was in compliance with all financial covenants under its credit facilities as of September 30, 2023.

On August 15, 2023, the Company issued $300.0 million in aggregate principal amount of the 2029 Notes for net proceeds of $292.9 million after deducting OID of $3.5 million, underwriting commissions and discounts of $3.0 million and offering costs of $0.6 million. Interest on the 2029 Notes is paid semi-annually on February 15 and August 15 at a rate of 7.100% per annum. In connection with the issuance of the 2029 Notes, the Company entered into an interest rate swap agreement under which the Company receives a fixed interest rate of 7.100% and pays a floating rate of the three-month SOFR plus 3.1255% on a notional amount of $300 million.

As of September 30, 2023, the Company had $136.5 million of unrestricted cash and cash equivalents and $907.5 million of undrawn capacity on its credit facilities (subject to borrowing base and other limitations). As of September 30, 2023, unfunded investment commitments were $232.7 million, or $205.6 million excluding unfunded commitments to the Company’s joint ventures. Of the $205.6 million, approximately $154.2 million could be drawn immediately with the remaining amount subject to certain milestones that must be met by portfolio companies. 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 take advantage of market opportunities in the current economic climate.

As of September 30, 2023, the weighted average interest rate on debt outstanding, including the effect of the interest rate swap agreement, was 7.0%, up from 6.6% as of June 30, 2023, primarily driven by the impact of higher interest rates on the Company’s floating rate liabilities and the issuance of the 2029 Notes.

The Company’s total debt to equity ratio was 1.10x and 1.18x as of September 30, 2023 and June 30, 2023, respectively. The Company’s net debt to equity ratio was 1.01x and 1.14x as of September 30, 2023 and June 30, 2023, 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.

• “Adjusted Net Investment Income” and “Adjusted Net Investment Income Per Share” – 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 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 and Unrealized 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 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 (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 fees¹, if any.

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 second amended and restated 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 and gain/loss resulting from the Mergers and are used by management to evaluate the economic earnings of its investment portfolio. Moreover,

¹ Adjusted earnings (loss) includes accrued Part II incentive fees. As of and for the three months and year ended September 30, 2023, 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 year ended September 30, 2023, no amounts were payable under the A&R Advisory Agreement.

7

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).
