(1)All debt investments are income producing unless otherwise noted. All equity investments are non-income producing unless otherwise noted.

(2)See Note 3 in the accompanying notes to the Consolidated Financial Statements for portfolio composition by geographic region.

(3)Equity ownership may be held in shares or units of companies related to the portfolio companies.

(4)Each of the Company's investments is pledged as collateral under one or more of its credit facilities. A single investment may be divided into parts that are individually pledged as collateral to separate credit facilities.

(5)Interest rates may be adjusted from period to period on certain term loans and revolvers. These rate adjustments may be either temporary in nature due to tier pricing arrangements or financial or payment covenant violations in the original credit agreements or permanent in nature per loan amendment or waiver documents.

(6)The interest rate on the principal balance outstanding for most of the floating rate loans is indexed to the secured overnight financing rate ("SOFR"), the euro interbank offered rate ("EURIBOR" or "E"), the sterling overnight index average ("SONIA") and/or an alternate base rate (e.g., prime rate), which typically resets semi-annually, quarterly, or monthly at the borrower's option. The borrower may also elect to have multiple interest reset periods for each loan. For each of these loans, the Company has provided the applicable margin over the reference rate based on each respective credit agreement and the cash interest rate as of period end. As of March 31, 2024, the reference rates for the Company's variable rate loans were the 30-day SOFR at 5.33%, the 90-day SOFR at 5.31%, the 180-day SOFR at 5.23%, the PRIME at 8.50%, the SONIA at 5.19% and the 90-day EURIBOR at 3.88%. Most loans include an interest floor, which generally ranges from 0% to 2.75%. SOFR and SONIA based contracts may include a credit spread adjustment that is charged in addition to the base rate and the stated spread.

(7)Principal includes accumulated payment in kind ("PIK") interest and is net of repayments, if any. “£” signifies the investment is denominated in British Pounds. "€" signifies the investment is denominated in Euros. All other investments are denominated in U.S. dollars.

(8)Control Investments generally are defined by the Investment Company Act of 1940, as amended (the "Investment Company Act"), as investments in companies in which the Company owns more than 25% of the voting securities or maintains greater than 50% of the board representation.

(9)As defined in the Investment Company Act, the Company is deemed to be both an "Affiliated Person" of and to "Control" these portfolio companies as the Company owns more than 25% of the portfolio company's outstanding voting securities or has the power to exercise control over management or policies of such portfolio company (including through a management agreement). See Schedule 12-14 in the accompanying notes to the Consolidated Financial Statements for transactions during the six months ended March 31, 2024 in which the issuer was both an Affiliated Person and a portfolio company that the Company is deemed to control.

(10)This investment represents a participation interest in the underlying securities shown.

(11)Investment is not a "qualifying asset" as defined under Section 55(a) of the Investment Company Act. Under the Investment Company Act, the Company may not acquire any non-qualifying asset unless, at the time the acquisition is made, qualifying assets represent at least 70% of the Company's total assets. As of March 31, 2024, qualifying assets represented 74.6% of the Company's total assets and non-qualifying assets represented 25.4% of the Company's total assets.

(12)Income producing through payment of dividends or distributions.

(13)This investment represents Seller Earn Out Shares in Alvotech SA. The Seller Earn Out Shares will vest if, at any time through June 16, 2027, the Alvotech SA common share price is at or above a volume weighted average price ("VWAP") of $20.00 per share for any ten trading days within any twenty trading day period.

(14)See Note 3 in the accompanying notes to the Consolidated Financial Statements for portfolio composition.

(15)As of March 31, 2024, these investments were categorized as Level 3 within the fair value hierarchy established by Financial Accounting Standards Board ("FASB") guidance under Accounting Standards Codification ("ASC") Topic 820, Fair Value Measurements and Disclosures ("ASC 820").

(16)This investment was valued using net asset value as a practical expedient for fair value. Consistent with ASC 820, these investments are excluded from the hierarchical levels.

(17)Affiliate Investments generally are defined by the Investment Company Act as investments in companies in which the Company owns between 5% and 25% of the voting securities.

(18)Non-Control/Non-Affiliate Investments are investments that are neither Control Investments nor Affiliate Investments.

(19)Investment had undrawn commitments. Unamortized fees are classified as unearned income which reduces cost basis, which may result in a negative cost basis. A negative fair value may result from the unfunded commitment being valued below par.

(20)This investment was on non-accrual status as of March 31, 2024.

(21)This investment represents a revenue interest financing term loan in which the Company receives periodic interest payments based on a percentage of revenues earned at the respective portfolio company over the life of the loan.

See notes to Consolidated Financial Statements.

Consolidated Schedule of Investments

September 30, 2023

(dollar amounts in thousands)

(1)All debt investments are income producing unless otherwise noted. All equity investments are non-income producing unless otherwise noted.

(2)See Note 3 in the accompanying notes to the Consolidated Financial Statements for portfolio composition by geographic region.

(3)Equity ownership may be held in shares or units of companies related to the portfolio companies.

(4)Each of the Company's investments is pledged as collateral under one or more of its credit facilities. A single investment may be divided into parts that are individually pledged as collateral to separate credit facilities.

(5)Interest rates may be adjusted from period to period on certain term loans and revolvers. These rate adjustments may be either temporary in nature due to tier pricing arrangements or financial or payment covenant violations in the original credit agreements or permanent in nature per loan amendment or waiver documents.

(6)The interest rate on the principal balance outstanding for most of the floating rate loans is indexed to SOFR, the London Interbank Offered Rate ("LIBOR" or "L"), SONIA and/or an alternate base rate (e.g., prime rate), which typically resets semi-annually, quarterly, or monthly at the borrower's option. The borrower may also elect to have multiple interest reset periods for each loan.

Note 2. Significant Accounting Policies

Basis of Presentation:

The Consolidated Financial Statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") and pursuant to the requirements for reporting on Form 10-Q and Regulation S-X. In the opinion of management, all adjustments of a normal recurring nature considered necessary for the fair presentation of the Consolidated Financial Statements have been made. All intercompany balances and transactions have been eliminated. The Company is an investment company following the accounting and reporting guidance in ASC Topic 946, Financial Services - Investment Companies ("ASC 946").

Certain prior period amounts have been reclassified to conform to the current period presentation. All per share amounts and common shares outstanding have been retroactively adjusted as necessary to reflect the Company's 1-for-3 reverse stock split completed on January 20, 2023 and effective as of the commencement of trading on January 23, 2023.

Use of Estimates:

The preparation of the financial statements in conformity with GAAP requires management to make certain estimates and assumptions affecting amounts reported in the financial statements and accompanying notes. These estimates are based on the information that is currently available to the Company and on various other assumptions that the Company believes to be reasonable under the circumstances. Changes in the economic and political environments, financial markets and any other parameters used in determining these estimates could cause actual results to differ and such differences could be material. Significant estimates include the valuation of investments and revenue recognition.

Consolidation:

The accompanying Consolidated Financial Statements include the accounts of Oaktree Specialty Lending Corporation and its consolidated subsidiaries. Each consolidated subsidiary is wholly-owned and, as such, consolidated into the Consolidated Financial Statements. Certain subsidiaries that hold investments are treated as pass through entities for U.S. federal income tax purposes. The assets of certain of the consolidated subsidiaries are not directly available to satisfy the claims of the creditors of Oaktree Specialty Lending Corporation or any of its other subsidiaries.

As an investment company, portfolio investments held by the Company are not consolidated into the Consolidated Financial Statements but rather are included on the Statements of Assets and Liabilities as investments at fair value.

Fair Value Measurements:

Oaktree, as the valuation designee of the Company's Board of Directors pursuant to Rule 2a-5 under the Investment Company Act, determines the fair value of our assets on at least a quarterly basis in accordance with ASC 820. ASC 820 defines fair value as the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. A liability's fair value is defined as the amount that would be paid to transfer the liability to a new obligor, not the amount that would be paid to settle the liability with the creditor. ASC 820 prioritizes the use of observable market prices over entity-specific inputs. Where observable prices or inputs are not available or reliable, valuation techniques are applied. These valuation techniques involve some level of management estimation and judgment, the degree of which is dependent on the price transparency for the investments or market and the investments' complexity.

Hierarchical levels, defined by ASC 820 and directly related to the amount of subjectivity associated with the inputs to fair valuation of these assets and liabilities, are as follows:

•Level 1 — Unadjusted, quoted prices in active markets for identical assets or liabilities as of the measurement date.

•Level 2 — Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data at the measurement date for substantially the full term of the assets or liabilities.

•Level 3 — Unobservable inputs that reflect Oaktree's best estimate of what market participants would use in pricing the asset or liability at the measurement date. Consideration is given to the risk inherent in the valuation technique and the risk inherent in the inputs to the model.

If inputs used to measure fair value fall into different levels of the fair value hierarchy, an investment's level is based on the lowest level of input that is significant to the fair value measurement. Oaktree's assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the investment.

OAKTREE SPECIALTY LENDING CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(in thousands, except share and per share amounts, percentages and as otherwise indicated)

This includes investment securities that are valued using "bid" and "ask" prices obtained from independent third party pricing services or directly from brokers. These investments may be classified as Level 3 because the quoted prices may be indicative in nature for securities that are in an inactive market, may be for similar securities or may require adjustments for investment-specific factors or restrictions.

Financial instruments with readily available quoted prices generally will have a higher degree of market price observability and a lesser degree of judgment inherent in measuring fair value. As such, Oaktree obtains and analyzes readily available market quotations provided by pricing vendors and brokers for all of the Company's investments for which quotations are available. In determining the fair value of a particular investment, pricing vendors and brokers use observable market information, including both binding and non-binding indicative quotations.

Oaktree seeks to obtain at least two quotations for the subject or similar securities, typically from pricing vendors. If Oaktree is unable to obtain two quotes from pricing vendors, or if the prices obtained from pricing vendors are not within Oaktree's set threshold, Oaktree seeks to obtain a quote directly from a broker making a market for the asset. Oaktree evaluates the quotations provided by pricing vendors and brokers based on available market information, including trading activity of the subject or similar securities, or by performing a comparable security analysis to ensure that fair values are reasonably estimated. Oaktree also performs back-testing of valuation information obtained from pricing vendors and brokers against actual prices received in transactions. In addition to ongoing monitoring and back-testing, Oaktree performs due diligence procedures over pricing vendors to understand their methodology and controls to support their use in the valuation process. Generally, Oaktree does not adjust any of the prices received from these sources.

If the quotations obtained from pricing vendors or brokers are determined to not be reliable or are not readily available, Oaktree values such investments using any of three different valuation techniques. The first valuation technique is the transaction precedent technique, which utilizes recent or expected future transactions of the investment to determine fair value, to the extent applicable. The second valuation technique is an analysis of the enterprise value ("EV") of the portfolio company. EV means the entire value of the portfolio company to a market participant, including the sum of the values of debt and equity securities used to capitalize the enterprise at a point in time. The EV analysis is typically performed to determine (i) the value of equity investments, (ii) whether there is credit impairment for debt investments and (iii) the value for debt investments that the Company is deemed to control under the Investment Company Act. To estimate the EV of a portfolio company, Oaktree analyzes various factors, including the portfolio company’s historical and projected financial results, macroeconomic impacts on the company and competitive dynamics in the company’s industry. Oaktree also utilizes some or all of the following information based on the individual circumstances of the portfolio company: (i) valuations of comparable public companies, (ii) recent sales of private and public comparable companies in similar industries or having similar business or earnings characteristics, (iii) purchase prices as a multiple of their earnings or cash flow, (iv) the portfolio company’s ability to meet its forecasts and its business prospects, (v) a discounted cash flow analysis, (vi) estimated liquidation or collateral value of the portfolio company's assets and (vii) offers from third parties to buy the portfolio company. Oaktree may probability weight potential sale outcomes with respect to a portfolio company when uncertainty exists as of the valuation date. The third valuation technique is a market yield technique, which is typically performed for non-credit impaired debt investments. In the market yield technique, a current price is imputed for the investment based upon an assessment of the expected market yield for a similarly structured investment with a similar level of risk, and Oaktree considers the current contractual interest rate, the capital structure and other terms of the investment relative to risk of the company and the specific investment. A key determinant of risk, among other things, is the leverage through the investment relative to the EV of the portfolio company. As debt investments held by the Company are substantially illiquid with no active transaction market, Oaktree depends on primary market data, including newly funded transactions and industry specific market movements, as well as secondary market data with respect to high yield debt instruments and syndicated loans, as inputs in determining the appropriate market yield, as applicable.

In accordance with ASC 820-10, certain investments that qualify as investment companies in accordance with ASC 946 may be valued using net asset value as a practical expedient for fair value. Consistent with FASB guidance under ASC 820, these investments are excluded from the hierarchical levels. These investments are generally not redeemable.

Oaktree estimates the fair value of certain privately held warrants using a Black Scholes pricing model, which includes an analysis of various factors and subjective assumptions, including the current stock price (by using an EV analysis as described above), the expected period until exercise, expected volatility of the underlying stock price, expected dividends and the risk free rate. Changes in the subjective input assumptions can materially affect the fair value estimates.

Rule 2a-5 under the Investment Company Act permits boards of directors of registered investment companies and Business Development Companies to either (i) choose to determine fair value in good faith or (ii) designate a valuation designee tasked with determining fair value in good faith, subject to the board’s oversight. The Company's Board of Directors has designated Oaktree to serve as its valuation designee effective September 8, 2022.

OAKTREE SPECIALTY LENDING CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(in thousands, except share and per share amounts, percentages and as otherwise indicated)

Oaktree undertakes a multi-step valuation process each quarter in connection with determining the fair value of the Company's investments:

•The quarterly valuation process begins with each portfolio company or investment being initially valued by Oaktree's valuation team;

•Preliminary valuations are then reviewed and discussed with management of Oaktree;

•Separately, independent valuation firms prepare valuations of the Company's investments, on a selected basis, for which market quotations are not readily available or are readily available but deemed not reflective of the fair value of the investment, and submit the reports to the Company and provide such reports to Oaktree;

•Oaktree compares and contrasts its preliminary valuations to the valuations of the independent valuation firms and prepares a valuation report for the Audit Committee;

•The Audit Committee reviews the valuation report with Oaktree, and Oaktree responds and supplements the valuation report to reflect any discussions between Oaktree and the Audit Committee; and

•Oaktree, as valuation designee, determines the fair value of each investment in the Company's portfolio.

The fair value of the Company's investments as of March 31, 2024 and September 30, 2023 was determined by Oaktree, as the Company's valuation designee. The Company has and will continue to engage independent valuation firms to provide assistance regarding the determination of the fair value of a portion of its portfolio securities for which market quotations are not readily available or are readily available but deemed not reflective of the fair value of the investment each quarter.

Due to the inherent uncertainty of determining the fair value of investments that do not have a readily available market value, the fair value of the Company’s investments may fluctuate from period to period. Because of the inherent uncertainty of valuation, these estimated values may differ significantly from the values that would have been reported had a ready market for the investments existed, and it is reasonably possible that the difference could be material.

With the exception of the line items entitled "deferred financing costs," "deferred offering costs," "other assets," "deferred tax liability," "credit facilities payable" and "unsecured notes payable," which are reported at amortized cost, all assets and liabilities approximate fair value on the Consolidated Statements of Assets and Liabilities. The carrying value of the line items titled "interest, dividends and fees receivable," "due from portfolio companies," "receivables from unsettled transactions," "due from broker," "accounts payable, accrued expenses and other liabilities," "base management fee and incentive fee payable," "due to affiliate," "interest payable" and "payables from unsettled transactions" approximate fair value due to their short maturities.

Foreign Currency Translation:

The accounting records of the Company are maintained in U.S. dollars. All assets and liabilities denominated in foreign currencies are translated into U.S. dollars based on the prevailing foreign exchange rate on the reporting date. The Company does not isolate that portion of the results of operations resulting from changes in foreign exchange rates on investments from the fluctuations arising from changes in market prices of securities held. The Company’s investments in foreign securities may involve certain risks, including foreign exchange restrictions, expropriation, taxation or other political, social or economic risks, all of which could affect the market and/or credit risk of the investment. In addition, changes in the relationship of foreign currencies to the U.S. dollar can significantly affect the value of these investments and therefore the earnings of the Company.

Derivative Instruments:

Foreign Currency Forward Contracts

The Company uses foreign currency forward contracts to reduce the Company's exposure to fluctuations in the value of foreign currencies. In a foreign currency forward contract, the Company agrees to receive or deliver a fixed quantity of one currency for another at a pre-determined price at a future date. Foreign currency forward contracts are marked-to-market at the applicable forward rate. Unrealized appreciation (depreciation) on foreign currency forward contracts is recorded within derivative assets or derivative liabilities on the Consolidated Statements of Assets and Liabilities by counterparty on a net basis, not taking into account collateral posted which is recorded separately, if applicable. Purchases and settlements of foreign currency forward contracts having the same settlement date and counterparty are generally settled net and any realized gains or losses are recognized on the settlement date. The Company does not utilize hedge accounting with respect to foreign currency forward contracts and, as such, the Company recognizes its foreign currency forward contracts at fair value with changes included in the net unrealized appreciation (depreciation) on the Consolidated Statements of Operations.

(in thousands, except share and per share amounts, percentages and as otherwise indicated)

Interest Rate Swaps

The Company uses interest rate swaps to hedge some of the Company's fixed rate debt. The Company designated the interest rate swaps as the hedging instruments in an effective hedge accounting relationship, and therefore the periodic payments are recognized as components of interest expense in the Consolidated Statements of Operations. Depending on the nature of the balance at period end, the fair value of each interest rate swap is either included as a derivative asset or derivative liability on the Company's Consolidated Statements of Assets and Liabilities. The change in fair value of the interest rate swaps is offset by a change in the carrying value of the fixed rate debt. Any amounts paid to the counterparty to cover collateral obligations under the terms of the interest rate swap agreements are included in due from broker on the Company's Consolidated Statements of Assets and Liabilities.

Investment Income:

Interest Income

Interest income, adjusted for accretion of original issue discount ("OID"), is recorded on an accrual basis to the extent that such amounts are expected to be collected. The Company stops accruing interest on investments when it is determined that interest is no longer collectible. Investments that are expected to pay regularly scheduled interest in cash are generally placed on non-accrual status when there is reasonable doubt that principal or interest cash payments will be collected. Cash interest payments received on investments may be recognized as income or a return of capital depending upon management’s judgment. A non-accrual investment is restored to accrual status if past due principal and interest are paid in cash and the portfolio company, in management’s judgment, is likely to continue timely payment of its remaining obligations. As of March 31, 2024, there were five investments on non-accrual status that in aggregate represented 4.3% and 2.4% of total debt investments at cost and fair value, respectively. As of September 30, 2023, there were four investments on non-accrual status that in aggregate represented 2.4% and 1.8% of total debt investments at cost and fair value, respectively.

In connection with its investment in a portfolio company, the Company sometimes receives nominal cost equity that is valued as part of the negotiation process with the portfolio company. When the Company receives nominal cost equity, the Company allocates its cost basis in the investment between debt securities and the nominal cost equity at the time of origination. Any resulting discount from recording the loan, or otherwise purchasing a security at a discount, is accreted into interest income over the life of the loan.

PIK Interest Income

The Company's investments in debt securities may contain PIK interest provisions. PIK interest, which generally represents contractually deferred interest added to the loan balance that is generally due at the end of the loan term, is generally recorded on the accrual basis to the extent such amounts are expected to be collected. The Company generally ceases accruing PIK interest if there is insufficient value to support the accrual or if the Company does not expect the portfolio company to be able to pay all principal and interest due. The Company's decision to cease accruing PIK interest on a loan or debt security involves subjective judgments and determinations based on available information about a particular portfolio company, including whether the portfolio company is current with respect to its payment of principal and interest on its loans and debt securities; financial statements and financial projections for the portfolio company; the Company's assessment of the portfolio company's business development success; information obtained by the Company in connection with periodic formal update interviews with the portfolio company's management and, if appropriate, the private equity sponsor; and information about the general economic and market conditions in which the portfolio company operates. The Company's determination to cease accruing PIK interest is generally made well before the Company's full write-down of a loan or debt security. In addition, if it is subsequently determined that the Company will not be able to collect any previously accrued PIK interest, the fair value of the loans or debt securities would be reduced by the amount of such previously accrued, but uncollectible, PIK interest. The accrual of PIK interest on the Company’s debt investments increases the recorded cost basis of these investments in the Consolidated Financial Statements including for purposes of computing the capital gains incentive fee payable by the Company to Oaktree. To maintain its status as a RIC, certain income from PIK interest may be required to be distributed to the Company’s stockholders, even though the Company has not yet collected the cash and may never do so.

(in thousands, except share and per share amounts, percentages and as otherwise indicated)

Fee Income

Oaktree or its affiliates may provide financial advisory services to portfolio companies and, in return, the Company may receive fees for capital structuring services. These fees are generally non-recurring and are recognized by the Company upon the investment closing date. The Company may also receive additional fees in the ordinary course of business, including servicing, amendment, exit and prepayment fees, which are classified as fee income and recognized as they are earned or the services are rendered.

Dividend Income

The Company generally recognizes dividend income on the ex-dividend date for public securities and the record date for private equity investments. Distributions received from private equity investments are evaluated to determine if the distribution should be recorded as dividend income or a return of capital. Generally, the Company will not record distributions from private equity investments as dividend income unless there are sufficient earnings at the portfolio company prior to the distribution. Distributions that are classified as a return of capital are recorded as a reduction in the cost basis of the investment.

Cash and Cash Equivalents and Restricted Cash:

Cash and cash equivalents consist of demand deposits and highly liquid investments with maturities of three months or less when acquired. The Company places its cash and cash equivalents and restricted cash with financial institutions and, at times, cash held in bank accounts exceeds the Federal Deposit Insurance Corporation ("FDIC") insurance limit. Cash and cash equivalents are included on the Company's Consolidated Schedule of Investments and cash equivalents are classified as Level 1 assets.

As of March 31, 2024, included in restricted cash was $12.5 million that was held at Deutsche Bank Trust Company Americas in connection with the OSI2 Citibank Facility (as defined in Note 6. Borrowings). Pursuant to the terms of the OSI2 Citibank Facility, the Company was restricted in terms of access to the $12.5 million until the occurrence of the periodic distribution dates and, in connection therewith, the Company’s submission of its required periodic reporting schedules and verifications of the Company’s compliance with the terms of the OSI2 Citibank Facility. As of September 30, 2023, included in restricted cash was $9.1 million that was held at Deutsche Bank Trust Company Americas in connection with the OSI2 Citibank Facility.

Due from Portfolio Companies:

Due from portfolio companies consists of amounts payable to the Company from its portfolio companies, including proceeds from the sale of portfolio companies not yet received or being held in escrow and excluding those amounts attributable to interest, dividends or fees receivable. These amounts are recognized as they become payable to the Company (e.g., principal payments on the scheduled amortization payment date).

Receivables/Payables from Unsettled Transactions:

Receivables/payables from unsettled transactions consist of amounts receivable to or payable by the Company for transactions that have not settled at the reporting date.

Deferred Financing Costs:

Deferred financing costs consist of fees and expenses paid in connection with the closing or amending of credit facilities and debt offerings. Deferred financing costs in connection with credit facilities are capitalized as an asset when incurred. Deferred financing costs in connection with all other debt arrangements are a direct deduction from the related debt liability when incurred. Deferred financing costs are amortized using the effective interest method over the term of the respective debt arrangement. This amortization expense is included in interest expense in the Consolidated Statements of Operations. Upon early termination or modification of a credit facility, all or a portion of unamortized fees related to such facility may be accelerated into interest expense. For extinguishments of the Company’s unsecured notes payable, any unamortized deferred financing costs are deducted from the carrying amount of the debt in determining the gain or loss from the extinguishment.

Deferred Offering Costs:

Legal fees and other costs incurred in connection with the Company’s shelf registration statement are capitalized as deferred offering costs in the Consolidated Statements of Assets and Liabilities. To the extent any such costs relate to equity offerings, these costs are charged as a reduction of capital upon utilization. To the extent any such costs relate to debt offerings, these costs are treated as deferred financing costs and are amortized over the term of the respective debt arrangement. Any

(in thousands, except share and per share amounts, percentages and as otherwise indicated)

deferred offering costs that remain at the expiration of the shelf registration statement or when it becomes probable that an offering will not be completed are expensed.

Income Taxes:

The Company has elected to be subject to tax as a RIC under Subchapter M of the Code and operates in a manner so as to qualify for the tax treatment applicable to RICs. In order to be subject to tax as a RIC, among other things, the Company is required to meet certain source of income and asset diversification requirements and timely distribute dividends to its stockholders of an amount generally at least equal to 90% of investment company taxable income, as defined by the Code and determined without regard to any deduction for dividends paid, for each taxable year. As a RIC, the Company is not subject to U.S. federal income tax on the portion of its taxable income and gains distributed currently to stockholders as a dividend. Depending on the level of taxable income earned during a taxable year, the Company may choose to retain taxable income in excess of current year dividend distributions and would distribute such taxable income in the next taxable year. The Company would then incur a 4% excise tax on such income, as required. To the extent that the Company determines that its estimated current year annual taxable income, determined on a calendar year basis, could exceed estimated current calendar year dividend distributions, the Company accrues excise tax, if any, on estimated excess taxable income as taxable income is earned. The Company anticipates timely distribution of its taxable income within the tax rules under Subchapter M of the Code. For calendar year 2022, the Company incurred $0.1 million of excise tax. The Company did not incur any U.S. federal excise tax for calendar year 2023. The Company does not expect to incur a U.S. federal excise tax for calendar year 2024.

The Company holds certain portfolio investments through taxable subsidiaries. The purpose of the Company's taxable subsidiaries is to permit the Company to hold equity investments in portfolio companies which are "pass through" entities for U.S. federal income tax purposes in order to comply with the RIC tax requirements. The taxable subsidiaries are consolidated for financial reporting purposes, and portfolio investments held by them are included in the Company’s Consolidated Financial Statements as portfolio investments and recorded at fair value. The taxable subsidiaries are not consolidated with the Company for U.S. federal income tax purposes and may generate income tax expense, or benefit, and the related tax assets and liabilities, as a result of their ownership of certain portfolio investments. This income tax expense, if any, would be reflected in the Company's Consolidated Statements of Operations. The Company uses the liability method to account for its taxable subsidiaries' income taxes. Using this method, the Company recognizes deferred tax assets and liabilities for the estimated future tax effects attributable to temporary differences between financial reporting and tax bases of assets and liabilities. In addition, the Company recognizes deferred tax benefits associated with net operating loss carry forwards that it may use to offset future tax obligations. The Company measures deferred tax assets and liabilities using the enacted tax rates expected to apply to taxable income in the years in which it expects to recover or settle those temporary differences.

FASB ASC Topic 740, Accounting for Uncertainty in Income Taxes ("ASC 740"), provides guidance for how uncertain tax positions should be recognized, measured, presented and disclosed in the Company's Consolidated Financial Statements. ASC 740 requires the evaluation of tax positions taken or expected to be taken in the course of preparing the Company's tax returns to determine whether the tax positions are "more-likely-than-not" of being sustained by the applicable tax authority. Tax positions not deemed to meet the more-likely-than-not threshold are recorded as a tax benefit or expense in the current year. Management's determinations regarding ASC 740 may be subject to review and adjustment at a later date based upon factors including an ongoing analysis of tax laws, regulations and interpretations thereof. The Company recognizes the tax benefits of uncertain tax positions only where the position is "more-likely-than-not" to be sustained assuming examination by tax authorities. Management has analyzed the Company's tax positions and has concluded that no liability for unrecognized tax benefits should be recorded related to uncertain tax positions taken on returns filed for open tax years 2021, 2022 and 2023. The Company identifies its major tax jurisdictions as U.S. Federal and California, and the Company is not aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will change materially in the next 12 months.

Recently Adopted Accounting Pronouncements

In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting (Topic 280), which improves reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The amendments are effective for fiscal years beginning after December 15, 2023 and interim period within fiscal years beginning after December 15, 2024. The Company does not expect this guidance to materially impact its consolidated financial statements.

(a)In accordance with ASC 820-10, certain investments that are measured using the net asset value per share (or its equivalent) as a practical expedient for fair value have not been classified in the fair value hierarchy. These investments are generally not redeemable. The fair value amounts presented in this table are intended to permit reconciliation of the fair value hierarchy to the amounts presented in the Consolidated Statements of Assets and Liabilities.

When a determination is made to classify a financial instrument within Level 3 of the valuation hierarchy, the determination is based upon the fact that the unobservable factors are significant to the overall fair value measurement. However, Level 3 financial instruments typically have both unobservable or Level 3 components and observable components (i.e. components that are actively quoted and can be validated by external sources). Accordingly, the appreciation (depreciation) in the tables below includes changes in fair value due in part to observable factors that are part of the valuation methodology. Transfers between levels are recognized at the beginning of the reporting period.

(f)Oaktree determined the value of its subordinated notes of each JV based on the total assets less the total liabilities senior to the subordinated notes held at such JV in an amount not exceeding par under the EV technique.

Under the market yield technique, the significant unobservable input used in the fair value measurement of the Company's investments in debt securities is the market yield. Increases or decreases in the market yield may result in a lower or higher fair value measurement, respectively.

Under the EV technique, the significant unobservable input used in the fair value measurement of the Company's investments in debt or equity securities is the earnings before interest, taxes, depreciation and amortization ("EBITDA"), revenue or asset multiple, as applicable. Increases or decreases in the valuation multiples in isolation may result in a higher or lower fair value measurement, respectively.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(in thousands, except share and per share amounts, percentages and as otherwise indicated)

As of March 31, 2024 and September 30, 2023, the Company had no single investment that represented greater than 10% of the total investment portfolio at fair value. Income, consisting of interest, dividends, fees, other investment income and realization of gains or losses, may fluctuate and in any given period can be highly concentrated among several investments.

Senior Loan Fund JV I, LLC

In May 2014, the Company entered into an LLC agreement with Kemper to form SLF JV I. The Company co-invests in senior secured loans of middle-market companies and other corporate debt securities with Kemper through its investment in SLF JV I. SLF JV I is managed by a four person Board of Directors, two of whom are selected by the Company and two of whom are selected by Kemper. All portfolio decisions and investment decisions in respect of SLF JV I must be approved by the SLF JV I investment committee, which consists of one representative selected by the Company and one representative selected by Kemper (with approval from a representative of each required). Since the Company does not have a controlling financial interest in SLF JV I, the Company does not consolidate SLF JV I.

SLF JV I is capitalized pro rata with LLC equity interests as transactions are completed and may be capitalized with additional subordinated notes issued to the Company and Kemper by SLF JV I.

_________

(1) Represents the interest rate as of March 31, 2024. All interest rates are payable in cash, unless otherwise noted.

(2) The interest rate on the principal balance outstanding for most of the floating rate loans is indexed to SOFR which typically resets semi-annually, quarterly, or monthly at the borrower's option. The borrower may also elect to have multiple interest reset periods for each loan. For each of these loans, the Company has provided the applicable margin over the reference rates based on each respective credit agreement and the cash interest rate as of period end. As of March 31, 2024, the reference rates for SLF JV I's variable rate loans were the 30-day SOFR at 5.33%, and the 90-day SOFR at 5.31%. Most loans include an interest floor, which generally ranges from 0% to 1%. SOFR based contracts may include a credit spread adjustment that is charged in addition to the base rate and the stated spread.

(3) Represents the current determination of fair value as of March 31, 2024 utilizing a similar technique as the Company in accordance with ASC 820. However, the determination of such fair value is not included in the valuation process described elsewhere herein.

(4) This investment was held by both the Company and SLF JV I as of March 31, 2024.

On March 19, 2021, the Company became party to the LLC agreement of Glick JV.

The Glick JV is managed by a four person Board of Directors, two of whom are selected by the Company and two of whom are selected by GF Equity Funding. The Glick JV is capitalized as transactions are completed, and portfolio decisions and investment decisions in respect of the Glick JV must be approved by the Glick JV investment committee, which consists of one representative selected by the Company and one representative selected by GF Equity Funding (with approval from a representative of each required). Since the Company does not have a controlling financial interest in the Glick JV, the Company does not consolidate the Glick JV.

The members provide capital to the Glick JV in exchange for LLC equity interests, and the Company and GF Debt Funding 2014 LLC ("GF Debt Funding"), an entity advised by affiliates of GF Equity Funding, provide capital to the Glick JV in exchange for subordinated notes issued by the Glick JV (the "Glick JV Notes").

(the "Glick JV Facility"), which, as of March 31, 2024, had a revolving period end date and maturity date of August 12, 2026 and August 17, 2026, respectively, and permitted borrowings of up to $80.0 million (subject to borrowing base and other limitations).

As of March 31, 2024, borrowings under the Glick JV Facility bore interest at a rate equal to daily SOFR plus 2.00% per annum. $74.0 million and $53.0 million of borrowings were outstanding under the Glick JV Deutsche Bank Facility as of March 31, 2024 and September 30, 2023, respectively.

The Glick JV's portfolio consisted of middle-market and other corporate debt securities of 49 and 38 portfolio companies as of March 31, 2024 and September 30, 2023, respectively.

Distributions

Distributions to common stockholders are recorded on the ex-dividend date. The amount to be paid out as a dividend is determined by the Board of Directors and is based on management’s estimate of the Company’s annual taxable income. Net realized capital gains, if any, may be distributed to stockholders or retained for reinvestment.

The Company has adopted a dividend reinvestment plan (“DRIP”) that provides for reinvestment of any distributions the Company declares in cash on behalf of its stockholders, unless a stockholder elects to receive cash. As a result, if the Company’s Board of Directors declares a cash distribution, then the Company’s stockholders who have not “opted out” of the Company’s DRIP will have their cash distribution automatically reinvested in additional shares of the Company’s common stock, rather than receiving the cash distribution. If the Company’s shares are trading at a premium to net asset value, the Company typically issues new shares to implement the DRIP with such shares issued at the greater of the most recently computed net asset value per share of common stock or 95% of the current market price per share of common stock on the payment date for such distribution. If the Company’s shares are trading at a discount to net asset value, the Company typically purchases shares in the open market in connection with the Company’s obligations under the DRIP.

For income tax purposes, the Company has reported its distributions for the 2023 calendar year as ordinary income. The character of such distributions was appropriately reported to the Internal Revenue Service and stockholders for the 2023 calendar year. To the extent the Company’s taxable earnings for a fiscal and taxable year fall below the amount of distributions paid for the fiscal and taxable year, a portion of the total amount of the Company’s distributions for the fiscal and taxable year is deemed a return of capital for U.S. federal income tax purposes to the Company’s stockholders.

OAKTREE SPECIALTY LENDING CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(in thousands, except share and per share amounts, percentages and as otherwise indicated)

mezzanine loans, high-yield securities, convertible securities, preferred stock, common stock and other investments. The Syndicated Facility further allows the Company to request letters of credit from ING Capital LLC, as the issuing bank.

As of March 31, 2024, the size of the Syndicated Facility was $1.218 billion. In addition, pursuant to an "accordion" feature, the Company may increase the size of the facility to up to the greater of $1.25 billion and the Company's net worth, as defined in the facility, under certain circumstances.

As of March 31, 2024, (i) the period during which the Company may make drawings with respect to $1.035 billion of commitments will expire on June 23, 2027 and the maturity date is June 23, 2028, (ii) the period during which the Company may make drawings with respect to the remaining commitments will expire on May 4, 2025 and the maturity date is May 4, 2026 and (iii) the interest rate margin for (a) SOFR loans (which may be 1- or 3-month, at the Company’s option) was 2.00% plus a SOFR adjustment which ranges between 0.11448% and 0.26161% and (b) alternate base rate loans was 1.00%.

The Syndicated Facility is secured by substantially all of the Company’s assets (excluding, among other things, investments held in and by certain subsidiaries of the Company (including OSI 2 Senior Lending SPV, LLC, or “OSI 2 SPV”) or investments in certain portfolio companies of the Company) and guaranteed by certain subsidiaries of the Company.

The Syndicated Facility requires the Company to, among other things, (i) make representations and warranties regarding the collateral as well as each of the Company’s portfolio companies’ businesses, (ii) agree to certain indemnification obligations, and (iii) comply with various affirmative and negative covenants, reporting requirements and other customary requirements for similar revolving credit facilities, including covenants related to: (A) limitations on the incurrence of additional indebtedness and liens, (B) limitations on certain investments, (C) limitations on certain asset transfers and restricted payments, (D) maintaining a certain minimum stockholders’ equity, (E) maintaining a ratio of total assets (less total liabilities) to total indebtedness, of the Company and its subsidiaries (subject to certain exceptions), of not less than 1.50 to 1.00, (F) maintaining a ratio of consolidated EBITDA to consolidated interest expense, of the Company and its subsidiaries (subject to certain exceptions), of not less than 2.25 to 1.00, (G) maintaining a minimum liquidity and net worth, and (H) limitations on the creation or existence of agreements that prohibit liens on certain properties of the Company and certain of its subsidiaries. The Syndicated Facility also includes usual and customary default provisions such as the failure to make timely payments under the facility, the occurrence of a change in control, and the failure by the Company to materially perform under the agreements governing the facility, which, if not complied with, could accelerate repayment under the facility. As of March 31, 2024, the Company was in compliance with all financial covenants under the Syndicated Facility. In addition to the asset coverage ratio described above, borrowings under the Syndicated Facility (and the incurrence of certain other permitted debt) are subject to compliance with a borrowing base that will apply different advance rates to different types of assets in the Company’s portfolio. Each loan or letter of credit originated or assumed under the Syndicated Facility is subject to the satisfaction of certain conditions.

As of March 31, 2024 and September 30, 2023, the Company had $450.0 million and $430.0 million of borrowings outstanding under the Syndicated Facility, which had a fair value of $450.0 million and $430.0 million, respectively.

61

OAKTREE SPECIALTY LENDING CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(in thousands, except share and per share amounts, percentages and as otherwise indicated)

wholly-owned and consolidated subsidiary, as the borrower, the Company, as collateral manager, each of the lenders from time to time party thereto, Citibank, N.A., as administrative agent, and Deutsche Bank Trust Company Americas, as collateral agent.

As of March 31, 2024, the Company was able to borrow up to $400 million under the OSI2 Citibank Facility (subject to borrowing base and other limitations). As of March 31, 2024, the OSI2 Citibank Facility had a reinvestment period through May 25, 2025, during which advances may be made, and matures on January 26, 2027. Following the reinvestment period, OSI 2 SPV will be required to make certain mandatory amortization payments. Borrowings under the OSI2 Citibank Facility bear interest payable quarterly at a rate per year equal to (a) in the case of a lender that is identified as a conduit lender, the lesser of (i) the applicable commercial paper rate for such conduit lender and (ii) SOFR plus 2.00% per annum on broadly syndicated loans and 2.75% on all other eligible loans and (b) for all other lenders, SOFR plus 2.00% per annum on broadly syndicated loans and 2.75% per annum on all other eligible loans, in all cases subject to a minimum overall rate of SOFR plus 2.50% per annum. After the reinvestment period, the applicable spread is 4.00% per year. There is also a non-usage fee of 0.50% per year on the unused portion of the OSI2 Citibank Facility, payable quarterly; provided that if the unused portion of the OSI2 Citibank Facility is greater than 30% of the commitments under the OSI2 Citibank Facility, the non-usage fee will be based on an unused portion of 30% of the commitments under the OSI2 Citibank Facility. The OSI2 Citibank Facility is secured by a first priority security interest in substantially all of OSI 2 SPV’s assets. As part of the OSI2 Citibank Facility, OSI 2 SPV is subject to certain limitations as to how borrowed funds may be used and the types of loans that are eligible to be acquired by OSI 2 SPV including restrictions on sector concentrations, loan size, tenor and minimum investment ratings (or estimated ratings). The OSI2 Citibank Facility also contains certain requirements relating to interest coverage, collateral quality and portfolio performance, certain violations of which could result in the acceleration of the amounts due under the OSI2 Citibank Facility.

As of each of March 31, 2024 and September 30, 2023, the Company had $280.0 million outstanding under the OSI2 Citibank Facility, which had a fair value of $280.0 million. The Company’s borrowings under the OSI2 Citibank Facility bore interest at a weighted average interest rate of 8.079% and 7.172% for the six months ended March 31, 2024 and the period from January 23, 2023 to March 31, 2023, respectively. For the three and six months ended March 31, 2024, the Company recorded interest expense (inclusive of fees) of $6.0 million and $12.1 million, respectively, related to the OSI2 Citibank Facility.

The OID on the 2025 Notes is amortized based on the effective interest method over the term of the 2025 Notes.

The 2025 Notes were issued pursuant to an indenture, dated April 30, 2012, as supplemented by the fifth supplemental indenture, dated February 25, 2020 (collectively, the "2025 Notes Indenture"), between the Company and Deutsche Bank Trust Company Americas (the "Trustee"). The 2025 Notes are the Company's general unsecured obligations that rank senior in right of payment to all of the Company's existing and future indebtedness that is expressly subordinated in right of payment to the 2025 Notes. The 2025 Notes rank equally in right of payment with all of the Company's existing and future liabilities that are not so subordinated. The 2025 Notes effectively rank junior to any of the Company's secured indebtedness (including unsecured indebtedness that the Company later secures) to the extent of the value of the assets securing such indebtedness. The 2025 Notes rank structurally junior to all existing and future indebtedness (including trade payables) incurred by the Company's subsidiaries, financing vehicles or similar facilities.

Interest on the 2025 Notes is paid semi-annually on February 25 and August 25 at a rate of 3.500% per annum. The 2025 Notes mature on February 25, 2025 and may be redeemed in whole or in part at any time or from time to time at the Company's option prior to maturity at par plus a “make-whole” premium, if applicable. In addition, holders of the 2025 Notes can require the Company to repurchase the 2025 Notes at 100% of their principal amount upon the occurrence of certain change of control events as described in the 2025 Notes Indenture. The 2025 Notes were issued in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof. During the three and six months ended March 31, 2024, the Company did not repurchase any of the 2025 Notes in the open market.

The 2025 Notes Indenture contains certain covenants, including covenants requiring the Company's compliance with the asset coverage requirements set forth in Section 18(a)(1)(A) as modified by Section 61(a)(1) and (2) of the Investment Company Act or any successor provisions (but giving effect to any exemptive relief granted to the Company by the U.S. Securities and Exchange Commission ("SEC")), as well as covenants requiring the Company to provide financial information to the holders of the 2025 Notes and the Trustee if the Company ceases to be subject to the reporting requirements of the

The OID on the 2027 Notes is amortized based on the effective interest method over the term of the 2027 Notes.

The 2027 Notes were issued pursuant to an indenture, dated April 30, 2012, as supplemented by the sixth supplemental indenture, dated May 18, 2021 (collectively, the "2027 Notes Indenture"), between the Company and the Trustee.

These covenants are subject to limitations and exceptions that are described in the 2027 Notes Indenture.

In connection with the 2027 Notes, the Company entered into an interest rate swap to more closely align the interest rates of its liabilities with its investment portfolio, which consists of predominately floating rate loans. Under the interest rate swap agreement, the Company receives a fixed interest rate of 2.700% and pays a floating interest rate of the three-month SOFR plus 1.658% plus a SOFR adjustment of 0.26161% on a notional amount of $350.0 million. The Company designated the interest rate swap as the hedging instrument in an effective hedge accounting relationship. See Note 12 for more information regarding the interest rate swap.

 Note 7. Taxable/Distributable Income and Dividend Distributions

Taxable income differs from net increase (decrease) in net assets resulting from operations primarily due to: (1) unrealized appreciation (depreciation) on investments and foreign currency, as gains and losses are not included in taxable income until they are realized; (2) origination and exit fees received in connection with investments in portfolio companies; (3) organizational costs; (4) income or loss recognition on exited investments; and (5) recognition of interest income on certain loans.

As of September 30, 2023, the Company had net capital loss carryforwards of $558.3 million to offset net capital gains that will not expire, to the extent available and permitted by U.S. federal income tax law, of which $70.3 million are available to offset future short-term capital gains and $488.0 million are available to offset future long-term capital gains. A portion of such net capital loss carryforwards represented a realized loss under sections 382 and 383 of the Code, which is carried forward to future years to offset future gains subject to certain limitations.

Listed below is a reconciliation of "net increase (decrease) in net assets resulting from operations" to taxable income for the three and six months ended March 31, 2024 and 2023.

	Three months ended March 31, 2024		Three months ended March 31, 2023		Six months ended March 31, 2024		Six months ended March 31, 2023

 __________

(1) The Company's taxable income for the three and six months ended March 31, 2024 is an estimate and will not be finally determined until the Company files its tax return for the fiscal year ending September 30, 2024. Therefore, the final taxable income may be different than the estimate.

The Company uses the liability method to account for its taxable subsidiaries' income taxes. Using this method, the Company recognizes deferred tax assets and liabilities for the estimated future tax effects attributable to temporary differences between financial reporting and tax bases of assets and liabilities. In addition, the Company recognizes deferred tax benefits associated with net loss carry forwards that it may use to offset future tax obligations. The Company measures deferred tax assets and liabilities using the enacted tax rates expected to apply to taxable income in the years in which it expects to recover or settle those temporary differences.

When assessing the realizability of deferred tax assets, the Company considers whether it is probable that some or all of the deferred tax assets will not be realized. In determining whether the deferred tax assets are realizable, the Company considers the period of expiration of the tax asset, historical and projected taxable income and tax liabilities for the tax jurisdiction in which the tax asset is located. The deferred tax asset recognized by the Company, as it relates to the higher tax basis in the carrying value of certain assets compared to the book basis of those assets, will be recognized in future years by these taxable entities. Deferred tax assets are based on the amount of the tax benefit that the Company’s management has determined is more likely than not to be realized in future periods. In determining the realizability of this tax benefit, management considered numerous factors that will give rise to pre-tax income in future periods. Among these are the historical and expected future

book and tax basis pre-tax income of the Company and unrealized gains in the Company’s assets at the determination date. Based on these and other factors, the Company determined that, as of March 31, 2024, $8.6 million of the $8.6 million deferred tax assets would not more likely than not be realized in future periods.

For the three months ended March 31, 2024, the Company recognized a total expense for income tax related to realized and unrealized gains (losses) of $0.2 million, which was composed primarily of a current income tax expense. For the three months ended March 31, 2023, the Company recognized a total expense for income tax related to realized and unrealized losses of $0.1 million, which was primarily current income tax expense.

For the six months ended March 31, 2024, the Company recognized a total expense for income tax related to realized and unrealized gains (losses) of $0.4 million, which was composed primarily of a current income tax expense. For the six months ended March 31, 2023, the Company recognized a total benefit for income tax related to realized and unrealized losses of $0.5 million, which was composed of (i) a current income tax benefit of approximately $0.4 million, and (ii) a deferred income tax benefit of approximately $0.1 million, which resulted from unrealized depreciation on investments held by the Company’s wholly-owned taxable subsidiaries.

As of September 30, 2023, the Company's last tax year end, the components of accumulated overdistributed earnings on a tax basis were as follows:

Undistributed ordinary income, net	$	33,525
Net realized capital losses	(509,832)
Unrealized losses, net	(175,031)
Accumulated overdistributed earnings	$	(651,338)

The aggregate cost of investments for U.S. federal income tax purposes was $3,070.0 million as of September 30, 2023. As of September 30, 2023, the aggregate gross unrealized appreciation for all investments in which there was an excess of value over cost for U.S. federal income tax purposes was $529.5 million. As of September 30, 2023, the aggregate gross unrealized depreciation for all investments in which there was an excess of cost for U.S. federal income tax purposes over value was $704.5 million. Net unrealized depreciation based on the aggregate cost of investments for U.S. federal income tax purposes was $175.0 million.

Note 8. Realized Gains or Losses and Net Unrealized Appreciation or Depreciation

Realized Gains or Losses

Realized gains or losses are measured by the difference between the net proceeds from the sale or redemption and the cost basis of the investment without regard to unrealized appreciation or depreciation previously recognized, and include investments written-off during the period, net of recoveries. Realized losses may also be recorded in connection with the Company's determination that certain investments are considered worthless securities and/or meet the conditions for loss recognition per the applicable tax rules.

During the three months ended March 31, 2024, the Company recorded an aggregate net realized loss of $6.6 million, which consisted of the following:

Net Unrealized Appreciation or Depreciation

Net unrealized appreciation or depreciation reflects the net change in the valuation of the portfolio pursuant to the Company's valuation guidelines and the reclassification of any prior period unrealized appreciation or depreciation.

During the three months ended March 31, 2024 and 2023, the Company recorded net unrealized depreciation of $25.3 million and $18.3 million, respectively. For the three months ended March 31, 2024, this consisted of $24.8 million of net unrealized depreciation on equity investments and $13.5 million of net unrealized depreciation on debt investments, partially offset by $10.9 million of net unrealized appreciation related to exited investments (a portion of which resulted in a reclassification to realized losses) and $2.2 million of net unrealized appreciation of foreign currency forward contracts. For the three months ended March 31, 2023, this consisted of $24.5 million of net unrealized depreciation on debt investments and $4.9 million of net unrealized depreciation related to exited investments (a portion of which resulted in a reclassification to realized gains), partially offset by $9.5 million of net unrealized appreciation on equity investments and $1.6 million of net unrealized appreciation of foreign currency forward contracts.

During the six months ended March 31, 2024 and 2023, the Company recorded net unrealized depreciation of $50.3 million and $41.3 million, respectively. For the six months ended March 31, 2024, this consisted of $43.6 million of net unrealized depreciation on equity investments, $36.3 million of net unrealized depreciation on debt investments and $5.6 million of net unrealized depreciation of foreign currency forward contracts, partially offset by $35.3 million of net unrealized appreciation related to exited investments (a portion of which resulted in a reclassification to realized losses). For the six months ended March 31, 2023, this consisted of $44.0 million of net unrealized depreciation on debt investments and $9.4 million of net unrealized depreciation of foreign currency forward contracts, partially offset by $8.3 million of net unrealized appreciation on equity investments and $3.8 million of net unrealized appreciation related to exited investments (a portion of which resulted in a reclassification to realized losses).

Note 9. Concentration of Credit Risks

The Company deposits its cash with financial institutions and at times such balances are in excess of the FDIC insurance limit. The Company limits its exposure to credit loss by depositing its cash with high credit quality financial institutions and monitoring their financial stability.

Note 10. Related Party Transactions

As of March 31, 2024 and September 30, 2023, the Company had a liability on its Consolidated Statements of Assets and Liabilities in the amount of $18.6 million and $19.5 million, respectively, reflecting the unpaid portion of the base management fees and incentive fees payable to Oaktree.

Investment Advisory Agreement

The Company is party to the Investment Advisory Agreement. Under the Investment Advisory Agreement, the Company pays Oaktree a fee for its services under the Investment Advisory Agreement consisting of two components: a base management fee and an incentive fee. The cost of both the base management fee payable to Oaktree and any incentive fees earned by Oaktree is ultimately borne by common stockholders of the Company.

The investment advisory agreement with Oaktree was amended and restated on March 19, 2021 in connection with the closing of the OCSI Merger and on January 23, 2023 in connection with the closing of OSI2 Merger. The term “Investment Advisory Agreement” refers collectively to the agreements with Oaktree.

(in thousands, except share and per share amounts, percentages and as otherwise indicated)

Unless earlier terminated as described below, the Investment Advisory Agreement will remain in effect from year-to-year if approved annually by the Board of Directors of the Company or by the affirmative vote of the holders of a majority of the Company’s outstanding voting securities, including, in either case, approval by a majority of the directors of the Company who are not interested persons. The Investment Advisory Agreement will automatically terminate in the event of its assignment. The Investment Advisory Agreement may be terminated by either party without penalty upon 60 days’ written notice to the other. The Investment Advisory Agreement may also be terminated, without penalty, upon the vote of a majority of the outstanding voting securities of the Company.

Base Management Fee

Under the Investment Advisory Agreement, the base management fee is calculated at an annual rate of 1.50% of total gross assets, including any investment made with borrowings, but excluding cash and cash equivalents. The base management fee is payable quarterly in arrears and the fee for any partial month or quarter is appropriately prorated. Effective May 3, 2019, the base management fee on the Company’s gross assets, including any investments made with borrowings, but excluding any cash and cash equivalents, that exceed the product of (A) 200% and (B) the Company’s net asset value will be 1.00%. For the avoidance of doubt, the 200% will be calculated in accordance with the Investment Company Act and will give effect to exemptive relief the Company received from the SEC with respect to debentures issued by a small business investment company subsidiary. In connection with the OCSI Merger, Oaktree waived an aggregate of $6 million of base management fees otherwise payable to Oaktree in the two years following the closing of the OCSI Merger on March 19, 2021 at a rate of $750,000 per quarter (with such amount appropriately prorated for any partial quarter). In connection with the OSI2 Merger, Oaktree waived an aggregate of $9.0 million of base management fees payable to Oaktree as follows: $6.0 million at a rate of $1.5 million per quarter (with such amount appropriately prorated for any partial quarter) in the first year following closing of the OSI2 Merger on January 23, 2023 and $3.0 million at a rate of $750,000 per quarter (with such amount appropriately prorated for any partial quarter) in the second year following closing of the OSI2 Merger.

On April 26, 2024, Oaktree waived additional base management fees such that the total amount of waived base management fees (including those waived in connection with the OSI2 Merger described above) will be $1.5 million for each of the three months ended March 31, 2024 and June 30, 2024. In addition, effective July 1, 2024, the base management fee will be calculated (net of base management fees previously waived by Oaktree) at an annual rate of 1.00% of total gross assets, including any investments made with borrowings, but excluding cash and cash equivalents.

For the three and six months ended March 31, 2024, the base management fee incurred under the Investment Advisory Agreement was $10.1 million (net of waiver) and $20.1 million (net of waiver), respectively. For the three and six months ended March 31, 2023, the base management fee incurred under the Investment Advisory Agreement was $9.7 million (net of waiver) and $18.9 million (net of waiver), respectively.

Incentive Fee

The incentive fee consists of two parts. Under the Investment Advisory Agreement, the first part of the incentive fee (the “incentive fee on income” or "Part I incentive fee") is calculated and payable quarterly in arrears based upon the “pre-incentive fee net investment income” of the Company for the immediately preceding quarter. The payment of the incentive fee on income is subject to payment of a preferred return to investors each quarter (i.e., a “hurdle rate”), expressed as a rate of return on the value of the Company’s net assets at the end of the most recently completed quarter, of 1.50%, subject to a “catch up” feature.

For this purpose, “pre-incentive fee net investment income” means interest income, dividend income and any other income (including any other fees such as commitment, origination, structuring, diligence and consulting fees or other fees that the Company receives from portfolio companies, other than fees for providing managerial assistance) accrued during the fiscal quarter, minus the Company’s operating expenses for the quarter (including the base management fee, expenses payable under the Administration Agreement and any interest expense and dividends paid on any issued and outstanding preferred stock, but excluding the incentive fee). Pre-incentive fee net investment income includes, in the case of investments with a deferred interest feature (such as OID debt, instruments with PIK interest and zero coupon securities), accrued income that the Company has not yet received in cash. Pre-incentive fee net investment income does not include any realized capital gains, realized capital losses or unrealized capital appreciation or depreciation. In addition, pre-incentive fee net investment income does not include any amortization or accretion of any purchase premium or purchase discount to interest income resulting solely from merger-related accounting adjustments in connection with the assets acquired in the OCSI Merger or in the OSI2 Merger, in each case, including any premium or discount paid for the acquisition of such assets, solely to the extent that the inclusion of such merger-related accounting adjustments, in the aggregate, would result in an increase in pre-incentive fee net investment income.

OAKTREE SPECIALTY LENDING CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(in thousands, except share and per share amounts, percentages and as otherwise indicated)

Under the Investment Advisory Agreement, the calculation of the incentive fee on income for each quarter is as follows:

•No incentive fee is payable to Oaktree in any quarter in which the Company’s pre-incentive fee net investment income does not exceed the preferred return rate of 1.50% (the “preferred return”) on net assets;

•100% of the Company’s pre-incentive fee net investment income, if any, that exceeds the preferred return but is less than or equal to 1.8182% in any fiscal quarter is payable to Oaktree. This portion of the incentive fee on income is referred to as the “catch-up” provision, and it is intended to provide Oaktree with an incentive fee of 17.5% on all of the Company’s pre-incentive fee net investment income when the Company’s pre-incentive fee net investment income exceeds 1.8182% on net assets in any fiscal quarter; and

•For any quarter in which the Company’s pre-incentive fee net investment income exceeds 1.8182% on net assets, the incentive fee on income is equal to 17.5% of the amount of the Company’s pre-incentive fee net investment income, as the preferred return and catch-up will have been achieved.

There is no accumulation of amounts on the hurdle rate from quarter to quarter and accordingly there is no clawback of amounts previously paid if subsequent quarters are below the quarterly hurdle.

For the three and six months ended March 31, 2024, the first part of the incentive fee (incentive fee on income) incurred under the Investment Advisory Agreement was $8.5 million and $17.5 million, respectively. For the three and six months ended March 31, 2023, the first part of the incentive fee (incentive fee on income) incurred under the Investment Advisory Agreement was $9.0 million and $16.7 million, respectively.

Under the Investment Advisory Agreement, the second part of the incentive fee (the "capital gains incentive fee") is determined and payable in arrears as of the end of each fiscal year (or upon termination of the Investment Advisory Agreement, as of the termination date) commencing with the fiscal year ended September 30, 2019 and equals 17.5% of the Company’s realized capital gains, if any, on a cumulative basis from the beginning of the fiscal year ended September 30, 2019 through the end of each subsequent fiscal year, computed net of all realized capital losses and unrealized capital depreciation on a cumulative basis, less the aggregate amount of any previously paid capital gain incentive fees under the Investment Advisory Agreement. Any realized capital gains, realized capital losses, unrealized capital appreciation and unrealized capital depreciation with respect to the Company’s portfolio as of the end of the fiscal year ended September 30, 2018 are excluded from the calculations of the second part of the incentive fee. In addition, the calculation of realized capital gains, realized capital losses and unrealized capital depreciation does (1) not include any such amounts resulting solely from merger-related accounting adjustments in connection with the assets acquired in the OCSI Merger or in the OSI2 Merger, in each case, including any premium or discount paid for the acquisition of such assets, solely to the extent that the inclusion of such merger-related accounting adjustments, in the aggregate, would result in an increase in the capital gains incentive fee, (2) include any such amounts associated with the investments acquired in the OCSI Merger for the period from October 1, 2018 to the date of closing of the OCSI Merger, solely to the extent that the exclusion of such amounts, in the aggregate, would result in an increase in the capital gains incentive fee and (3) include any such amounts associated with the investments acquired in the OSI2 Merger for the period from August 6, 2018 to the date of closing of the OSI2 Merger, solely to the extent that the exclusion of such amounts, in the aggregate, would result in an increase in the capital gains incentive fee. As of March 31, 2024, the Company paid $9.6 million of capital gains incentive fees cumulatively under the Investment Advisory Agreement (net of waivers). Part II incentive fees are contractually calculated and paid at the end of the fiscal year in accordance with the Investment Advisory Agreement, which, as described above, differs from Part II incentive fees accrued under GAAP. Hypothetically, if Part II incentive fees were calculated as of March 31, 2024 under the Investment Advisory Agreement, no Part II incentive fees would be payable.

GAAP requires that the capital gains incentive fee accrual consider the cumulative aggregate unrealized capital appreciation in the calculation, as a capital gains incentive fee would be payable if such unrealized capital appreciation were realized on a theoretical "liquidation basis." A fee so calculated and accrued would not be payable under applicable law and may never be paid based upon the computation of capital gains incentive fees in subsequent periods. Amounts ultimately paid under the Investment Advisory Agreement will be consistent with the formula reflected in the Investment Advisory Agreement. This GAAP accrual is calculated using the aggregate cumulative realized capital gains and losses and aggregate cumulative unrealized capital depreciation included in the calculation of the capital gains incentive fee plus the aggregate cumulative unrealized capital appreciation. Any realized capital gains and losses and cumulative unrealized capital appreciation and depreciation with respect to the Company’s portfolio as of the end of the fiscal year ended September 30, 2018 are excluded from the GAAP accrual. If such amount is positive at the end of a period, then GAAP requires the Company to record a capital gains incentive fee equal to 17.5% of such cumulative amount, less the aggregate amount of actual capital gains incentive fees payable or capital gains incentive fees accrued under GAAP in all prior periods. The resulting accrual for any capital gains incentive fee under GAAP in a given period may result in an additional expense if such cumulative amount is greater than in the prior period or a reversal of previously recorded expense if such cumulative amount is less than in the prior period. If such cumulative amount is negative, then there is no accrual. There can be no assurance that such unrealized capital appreciation will

(in thousands, except share and per share amounts, percentages and as otherwise indicated)

be realized in the future or any accrued capital gains incentive fee will become payable under the Investment Advisory Agreement. For the three and six months ended March 31, 2024 and 2023, there were no accrued capital gains incentive fees. As of March 31, 2024, the total accrued capital gains incentive fee liability was zero.

Indemnification

The Investment Advisory Agreement provides that, absent willful misfeasance, bad faith or gross negligence in the performance of their respective duties or by reason of the reckless disregard of their respective duties and obligations, Oaktree and its officers, managers, partners, members (and their members, including the owners of their members), agents, employees, controlling persons and any other person or entity affiliated with it, are entitled to indemnification from the Company for any damages, liabilities, costs and expenses (including reasonable attorneys' fees and amounts reasonably paid in settlement) arising from the rendering of Oaktree's services under the Investment Advisory Agreement or otherwise as investment adviser.

Administrative Services

The Company is party to the Administration Agreement with Oaktree Administrator. Pursuant to the Administration Agreement, Oaktree Administrator provides administrative services to the Company necessary for the operations of the Company, which include providing office facilities, equipment, clerical, bookkeeping and record keeping services at such facilities and such other services as Oaktree Administrator, subject to review by the Company’s Board of Directors, shall from time to time deem to be necessary or useful to perform its obligations under the Administration Agreement. Oaktree Administrator may, on behalf of the Company, conduct relations and negotiate agreements with custodians, trustees, depositories, attorneys, underwriters, brokers and dealers, corporate fiduciaries, insurers, banks and such other persons in any such other capacity deemed to be necessary or desirable. Oaktree Administrator makes reports to the Company’s Board of Directors of its performance of obligations under the Administration Agreement and furnishes advice and recommendations with respect to such other aspects of the Company’s business and affairs, in each case, as it shall determine to be desirable or as reasonably required by the Company’s Board of Directors; provided that Oaktree Administrator shall not provide any investment advice or recommendation.

Oaktree Administrator also provides portfolio collection functions for interest income, fees and warrants and is responsible for the financial and other records that the Company is required to maintain and prepares, prints and disseminates reports to the Company’s stockholders and all other materials filed with the SEC. In addition, Oaktree Administrator assists the Company in determining and publishing the Company’s net asset value, overseeing the preparation and filing of the Company’s tax returns, and generally overseeing the payment of the Company’s expenses and the performance of administrative and professional services rendered to the Company by others. Oaktree Administrator may also offer to provide, on the Company’s behalf, managerial assistance to the Company’s portfolio companies.

For providing these services, facilities and personnel, the Company reimburses Oaktree Administrator the allocable portion of overhead and other expenses incurred by Oaktree Administrator in performing its obligations under the Administration Agreement, including the Company’s allocable portion of the rent of the Company’s principal executive offices (which are located in a building owned by a Brookfield affiliate) at market rates and the Company’s allocable portion of the costs of compensation and related expenses of its Chief Financial Officer, Chief Compliance Officer, their staffs and other non-investment professionals at Oaktree that perform duties for the Company. Such reimbursement is at cost, with no profit to, or markup by, Oaktree Administrator. The Administration Agreement may be terminated by either party without penalty upon 60 days’ written notice to the other.

Business Overview

We are a specialty finance company dedicated to providing customized, one-stop credit solutions to companies with limited access to public or syndicated capital markets. We are a closed-end, externally managed, non-diversified management investment company that has elected to be regulated as a Business Development Company under the Investment Company Act of 1940, as amended, or the Investment Company Act. In addition, we have qualified and elected to be treated as a RIC under the Internal Revenue Code of 1986, as amended, or the Code, for U.S. federal income tax purposes.

We are externally managed by Oaktree pursuant to an investment advisory agreement, as amended from time to time, or the Investment Advisory Agreement. Oaktree Fund Administration, LLC, or Oaktree Administrator, an affiliate of Oaktree,

80

provides certain administrative and other services necessary for us to operate pursuant to an administration agreement, as amended from time to time, or the Administration Agreement.

Our investment objective is to generate current income and capital appreciation by providing companies with flexible and innovative financing solutions, including first and second lien loans, unsecured and mezzanine loans, bonds, preferred equity and certain equity co-investments. We may also seek to generate capital appreciation and income through secondary investments at discounts to par in either private or syndicated transactions. Our portfolio may also include certain structured finance and other non-traditional structures. We invest in companies that typically possess resilient business models with strong underlying fundamentals. We intend to deploy capital across credit and economic cycles with a focus on long-term results, which we believe will enable us to build lasting partnerships with financial sponsors and management teams, and we may seek to opportunistically take advantage of dislocations in the financial markets and other situations that may benefit from Oaktree’s credit and structuring expertise. Sponsors may include financial sponsors, such as an institutional investor or a private equity firm, or a strategic entity seeking to invest in a portfolio company. We generally invest in securities that are rated below investment grade by rating agencies or that would be rated below investment grade if they were rated. Below investment grade securities, which are often referred to as “high yield” and “junk,” have predominantly speculative characteristics with respect to the issuer’s capacity to pay interest and repay principal.

In the current market environment, Oaktree intends to focus on the following areas, in which Oaktree believes there is less competition and thus potential for greater returns, for our new investment opportunities: (1) situational lending, which we define to include directly originated loans to non-sponsor companies that are hard to understand and value using traditional underwriting techniques, (2) select sponsor lending, which we define to include financing to support leveraged buyouts of companies with specialized sponsors that have expertise in certain industries, (3) stressed sector and rescue lending, which we define to include opportunistic private loans in industries experiencing stress or limited access to capital and (4) public credit, where we seek discounted, high quality public debt investments particularly in times of market dislocation.

On January 23, 2023, we acquired Oaktree Strategic Income II, Inc. (“OSI2”) pursuant to that certain Agreement and Plan of Merger (the “OSI2 Merger Agreement”), dated as of September 14, 2022, by and among OSI2, the Company, Project Superior Merger Sub, Inc., our wholly-owned subsidiary , and, solely for the limited purposes set forth therein, Oaktree. Pursuant to the OSI2 Merger Agreement, OSI2 was merged with and into us in a two-step transaction with us as the surviving company (the “OSI2 Merger”).

Business Environment and Developments

Global financial markets have experienced an increase in volatility as concerns about the impact of higher inflation, elevated interest rates, a potential slowdown in economic activity and the current conflicts in the Middle East have weighed on market participants. These factors have created disruptions in supply chains and economic activity and have had a particularly adverse impact on certain companies in the energy, raw materials and transportation sectors, among others. These uncertainties can ultimately impact the overall supply and demand of the market through changing spreads, deal terms and structures and equity purchase price multiples.

We are unable to predict the full effects of these macroeconomic events or how they might evolve. We continue to closely monitor the impact these events have on our business, industry and portfolio companies and will provide constructive solutions where necessary.

Against this backdrop, we believe attractive risk-adjusted returns can be achieved by making loans to middle market companies that typically possess resilient business models with strong underlying fundamentals. Given the breadth of the investment platform and decades of credit investing experience of Oaktree and its affiliates, we believe that we have the resources and experience to source, diligence and structure investments in these companies.

Critical Accounting Estimates

Fair Value Measurements

Oaktree, as the valuation designee of our Board of Directors pursuant to Rule 2a-5 under the Investment Company Act, determines the fair value of our assets on at least a quarterly basis in accordance with Financial Accounting Standards Board, or FASB, Accounting Standards Codification, or ASC, Topic 820, Fair Value Measurements and Disclosures, or ASC 820. ASC 820 defines fair value as the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. A liability’s fair value is defined as the amount that would be paid to transfer the liability to a new obligor, not the amount that would be paid to settle the liability with the creditor. ASC 820 prioritizes the use of observable market prices over entity-specific inputs. Where observable prices or inputs are not available or reliable, valuation techniques are applied. These valuation techniques involve some level of management estimation and judgment, the degree of which is dependent on the price transparency for the investments or market and the investments’ complexity.

Hierarchical levels, defined by ASC 820 and directly related to the amount of subjectivity associated with the inputs to fair valuation of these assets and liabilities, are as follows:

•Level 1 — Unadjusted, quoted prices in active markets for identical assets or liabilities as of the measurement date.

•Level 2 — Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data at the measurement date for substantially the full term of the assets or liabilities.

•Level 3 — Unobservable inputs that reflect Oaktree’s best estimate of what market participants would use in pricing the asset or liability at the measurement date. Consideration is given to the risk inherent in the valuation technique and the risk inherent in the inputs to the model.

If inputs used to measure fair value fall into different levels of the fair value hierarchy, an investment's level is based on the lowest level of input that is significant to the fair value measurement. Oaktree's assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the investment. This includes investment securities that are valued using "bid" and "ask" prices obtained from independent third party pricing services or directly from brokers. These investments may be classified as Level 3 because the quoted prices may be indicative in nature for securities that are in an inactive market, may be for similar securities or may require adjustments for investment-specific factors or restrictions.

Financial instruments with readily available quoted prices generally will have a higher degree of market price observability and a lesser degree of judgment inherent in measuring fair value. As such, Oaktree obtains and analyzes readily available market quotations provided by pricing vendors and brokers for all of our investments for which quotations are available. In determining the fair value of a particular investment, pricing vendors and brokers use observable market information, including both binding and non-binding indicative quotations.

Oaktree seeks to obtain at least two quotations for the subject or similar securities, typically from pricing vendors. If Oaktree is unable to obtain two quotes from pricing vendors, or if the prices obtained from pricing vendors are not within our set threshold, Oaktree seeks to obtain a quote directly from a broker making a market for the asset. Oaktree evaluates the

82

quotations provided by pricing vendors and brokers based on available market information, including trading activity of the subject or similar securities, or by performing a comparable security analysis to ensure that fair values are reasonably estimated. Oaktree also performs back-testing of valuation information obtained from pricing vendors and brokers against actual prices received in transactions. In addition to ongoing monitoring and back-testing, Oaktree performs due diligence procedures over pricing vendors to understand their methodology and controls to support their use in the valuation process. Generally, Oaktree does not adjust any of the prices received from these sources.

If the quotations obtained from pricing vendors or brokers are determined to not be reliable or are not readily available, Oaktree values such investments using any of three different valuation techniques. The first valuation technique is the transaction precedent technique, which utilizes recent or expected future transactions of the investment to determine fair value, to the extent applicable. The second valuation technique is an analysis of the enterprise value, or EV, of the portfolio company. EV means the entire value of the portfolio company to a market participant, including the sum of the values of debt and equity securities used to capitalize the enterprise at a point in time. The EV analysis is typically performed to determine (i) the value of equity investments, (ii) whether there is credit impairment for debt investments and (iii) the value for debt investments that we are deemed to control under the Investment Company Act. To estimate the EV of a portfolio company, Oaktree analyzes various factors, including the portfolio company’s historical and projected financial results, macroeconomic impacts on the company and competitive dynamics in the company’s industry. Oaktree also utilizes some or all of the following information based on the individual circumstances of the portfolio company: (i) valuations of comparable public companies, (ii) recent sales of private and public comparable companies in similar industries or having similar business or earnings characteristics, (iii) purchase prices as a multiple of their earnings or cash flow, (iv) the portfolio company’s ability to meet its forecasts and its business prospects, (v) a discounted cash flow analysis, (vi) estimated liquidation or collateral value of the portfolio company’s assets and (vii) offers from third parties to buy the portfolio company. Oaktree may probability weight potential sale outcomes with respect to a portfolio company when uncertainty exists as of the valuation date. Under the EV technique, the significant unobservable input used in the fair value measurement of our investments in debt or equity securities is the EBITDA, revenue or asset multiple, as applicable. Increases or decreases in the valuation multiples in isolation may result in a higher or lower fair value measurement, respectively. The third valuation technique is a market yield technique, which is typically performed for non-credit impaired debt investments. In the market yield technique, a current price is imputed for the investment based upon an assessment of the expected market yield for a similarly structured investment with a similar level of risk, and we consider the current contractual interest rate, the capital structure and other terms of the investment relative to risk of the company and the specific investment. A key determinant of risk, among other things, is the leverage through the investment relative to the EV of the portfolio company. As debt investments held by us are substantially illiquid with no active transaction market, Oaktree depends on primary market data, including newly funded transactions and industry-specific market movements, as well as secondary market data with respect to high yield debt instruments and syndicated loans, as inputs in determining the appropriate market yield, as applicable. Under the market yield technique, the significant unobservable input used in the fair value measurement of our investments in debt securities is the market yield. Increases or decreases in the market yield may result in a lower or higher fair value measurement, respectively.

In accordance with ASC 820-10, certain investments that qualify as investment companies in accordance with ASC 946 may be valued using net asset value as a practical expedient for fair value. Consistent with FASB guidance under ASC 820, these investments are excluded from the hierarchical levels. These investments are generally not redeemable.

Oaktree estimates the fair value of certain privately held warrants using a Black Scholes pricing model, which includes an analysis of various factors and subjective assumptions, including the current stock price (by using an EV analysis as described above), the expected period until exercise, expected volatility of the underlying stock price, expected dividends and the risk-free rate. Changes in the subjective input assumptions can materially affect the fair value estimates.

The fair value of our investments as of March 31, 2024 and September 30, 2023 was determined by Oaktree, as our valuation designee. We have and will continue to engage independent valuation firms to provide assistance each quarter regarding the determination of the fair value of a portion of our portfolio securities for which market quotations are not readily available or are readily available but deemed not reflective of the fair value of the investment. As of March 31, 2024, 99.9% of our portfolio at fair value was valued either based on market quotations, the transactions precedent approach or corroborated by independent valuation firms.

Certain factors that may be considered in determining the fair value of our investments include the nature and realizable value of any collateral, the portfolio company’s earnings and its ability to make payments on its indebtedness, the markets in which the portfolio company does business, comparison to comparable publicly-traded companies, discounted cash flow and other relevant factors. Because such valuations, and particularly valuations of private securities and private companies, are inherently uncertain, may fluctuate over short periods of time and may be based on estimates, Oaktree's determinations of fair value may differ materially from the values that would have been used if a ready market for these securities existed. Due to these uncertainties, Oaktree's fair value determinations may cause our net asset value on a given date to materially understate or overstate the value that we may ultimately realize upon the sale of one or more of our investments.

83

As of March 31, 2024, we held $3,047.4 million of investments at fair value, up from $2,892.4 million held at September 30, 2023, primarily driven by purchases of investments during the six months ended March 31, 2024. As of March 31, 2024 and September 30, 2023, approximately 92.4% and 89.9%, respectively, of our total assets represented investments at fair value.

Revenue Recognition

We generate revenues in the form of interest income on debt investments and, to a lesser extent, capital gains and distributions, if any, on equity securities that we may acquire in portfolio companies. We may also generate revenue in the form of commitment, origination, structuring or diligence fees, fees for providing managerial assistance and consulting fees. Some of our investments provide for deferred interest payments or payment-in-kind, or PIK, interest income. The principal amount of the debt investments and any accrued but unpaid interest generally becomes due at the maturity date.

Interest Income

Interest income, adjusted for accretion of original issue discount, or OID, is recorded on an accrual basis to the extent that such amounts are expected to be collected. We stop accruing interest on investments when it is determined that interest is no longer collectible. Investments that are expected to pay regularly scheduled interest in cash are generally placed on non-accrual status when there is reasonable doubt that principal or interest cash payments will be collected. Cash interest payments received on investments may be recognized as income or a return of capital depending upon management’s judgment. A non-accrual investment is restored to accrual status if past due principal and interest are paid in cash, and the portfolio company, in management’s judgment, is likely to continue timely payment of its remaining obligations. As of March 31, 2024, there were five investments on non-accrual status that in the aggregate represented 4.3% and 2.4% of total debt investments at cost and fair value, respectively. As of September 30, 2023, there were there four investments on non-accrual status that in aggregate represented 2.4% and 1.8% of total debt investments at cost and fair value, respectively.

In connection with our investment in a portfolio company, we sometimes receive nominal cost equity that is valued as part of the negotiation process with the portfolio company. When we receive nominal cost equity, we allocate our cost basis in the investment between debt securities and the nominal cost equity at the time of origination. Any resulting discount from recording the loan, or otherwise purchasing a security at a discount, is accreted into interest income over the life of the loan.

PIK Interest Income

Our investments in debt securities may contain PIK interest provisions. PIK interest, which typically represents contractually deferred interest added to the loan balance that is generally due at the end of the loan term, is generally recorded on the accrual basis to the extent such amounts are expected to be collected. We generally cease accruing PIK interest if there is insufficient value to support the accrual or if we do not expect the portfolio company to be able to pay all principal and interest due. Our decision to cease accruing PIK interest on a loan or debt security involves subjective judgments and determinations based on available information about a particular portfolio company, including whether the portfolio company is current with respect to its payment of principal and interest on its loans and debt securities; financial statements and financial projections for the portfolio company; our assessment of the portfolio company's business development success; information obtained by us in connection with periodic formal update interviews with the portfolio company's management and, if appropriate, the private equity sponsor; and information about the general economic and market conditions in which the portfolio company operates. Our determination to cease accruing PIK interest is generally made well before our full write-down of a loan or debt security. In addition, if it is subsequently determined that we will not be able to collect any previously accrued PIK interest, the fair value of the loans or debt securities would be reduced by the amount of such previously accrued, but uncollectible, PIK interest. The accrual of PIK interest on our debt investments increases the recorded cost bases of these investments in our Consolidated Financial Statements including for purposes of computing the capital gains incentive fee payable by us to Oaktree. To maintain our status as a RIC, certain income from PIK interest may be required to be distributed to our stockholders, even though we have not yet collected the cash and may never do so.

Portfolio Composition

Our investments principally consist of loans, common and preferred equity and warrants in privately-held companies, Senior Loan Fund JV I, LLC, or SLF JV I, a joint venture through which we and Trinity Universal Insurance Company, a

subsidiary of Kemper Corporation, or Kemper, co-invest in senior secured loans of middle-market companies and other corporate debt securities, and OCSI Glick JV LLC, or the Glick JV, a joint venture through which we and GF Equity Funding 2014 LLC, or GF Equity Funding, co- invest primarily in senior secured loans of middle-market companies. We refer to SLF JV I and the Glick JV collectively as the JVs. Our loans are typically secured by a first, second or subordinated lien on the assets of the portfolio company and generally have terms of up to ten years (but an expected average life of between three and four years).

84

During the six months ended March 31, 2024, we originated $765.9 million of investment commitments in 34 new and 25 existing portfolio companies and funded $745.0 million of investments.

During the six months ended March 31, 2024, we received $536.2 million of proceeds from prepayments, exits, other paydowns and sales and exited 25 portfolio companies.

The Joint Ventures

Senior Loan Fund JV I, LLC

In May 2014, we entered into a limited liability company, or LLC, agreement with Kemper to form SLF JV I. We co-invest in senior secured loans of middle-market companies and other corporate debt securities with Kemper through our investment in SLF JV I. SLF JV I is managed by a four person Board of Directors, two of whom are selected by us and two of whom are selected by Kemper. All portfolio decisions and investment decisions in respect of SLF JV I must be approved by the SLF JV I investment committee, which consists of one representative selected by us and one representative selected by Kemper (with approval from a representative of each required). Since we do not have a controlling financial interest in SLF JV I, we do not consolidate SLF JV I. SLF JV I is not an "eligible portfolio company" as defined in section 2(a)(46) of the Investment Company Act. SLF JV I is capitalized pro rata with LLC equity interests as transactions are completed and may be capitalized with additional subordinated notes issued to us and Kemper by SLF JV I. The subordinated notes issued by SLF JV I are referred to as the SLF JV I Notes. The SLF JV I Notes are senior in right of payment to SLF JV I LLC equity interests and subordinated in right of payment to SLF JV I’s secured debt.

As of March 31, 2024 and September 30, 2023, we and Kemper owned, in the aggregate, 87.5% and 12.5%, respectively, of the LLC equity interests of SLF JV I and the outstanding SLF JV I Notes. As of each of March 31, 2024 and September 30, 2023, we and Kemper had funded approximately $190.5 million to SLF JV I, of which $166.7 million was from us. As of each of March 31, 2024 and September 30, 2023, we had aggregate commitments to fund SLF JV I of $13.1 million, of which approximately $9.8 million was to fund additional SLF JV I Notes and approximately $3.3 million was to fund LLC equity interests in SLF JV I.

Both the cost and fair value of our SLF JV I Notes were $112.7 million as of each of March 31, 2024 and September 30, 2023. We earned interest income of $3.5 million and $7.1 million on the SLF JV I Notes for the three and six months ended March 31, 2024, respectively. We earned interest income of $3.2 million and $5.8 million on the SLF JV I Notes for the three and six months ended March 31, 2023, respectively. As of March 31, 2024, the SLF JV I Notes bore interest at a rate of one-month SOFR plus 7.00% per annum with a SOFR floor of 1.00% and will mature on December 29, 2028.

The cost and fair value of the LLC equity interests in SLF JV I held by us was $54.8 million and $29.7 million, respectively, as of March 31, 2024, and $54.8 million and $28.9 million, respectively, as of September 30, 2023. We earned $1.4 million and $2.8 million in dividend income for the three and six months ended March 31, 2024, respectively, with respect to our investment in the LLC equity interests of SLF JV I. We earned $1.1 million and $2.1 million in dividend income for the three and six months ended March 31, 2023, respectively, with respect to its investment in the LLC equity interests of SLF JV I.

Below is a summary of SLF JV I's portfolio as of March 31, 2024 and September 30, 2023:

	March 31, 2024	September 30, 2023
Senior secured loans (1)	$370,208	$332,637
Weighted average interest rate on senior secured loans (2)	10.09%	10.62%

88

JV in exchange for LLC equity interests, and we and GF Debt Funding, an entity advised by affiliates of GF Equity Funding, provide capital to the Glick JV in exchange for subordinated notes issued by the Glick JV, or the Glick JV Notes.

Approximately $84.0 million in aggregate commitments was funded as of each of March 31, 2024 and September 30, 2023, of which $73.5 million was from us. As of each of March 31, 2024 and September 30, 2023, we had commitments to fund Glick JV Notes of $78.8 million, of which $12.4 million was unfunded. As of each of March 31, 2024 and September 30, 2023, we had commitments to fund LLC equity interests in the Glick JV of $8.7 million, of which $1.6 million was unfunded.

The cost and fair value of our aggregate investment in the Glick JV was $51.0 million and $51.3 million, respectively, as of March 31, 2024. The cost and fair value of our aggregate investment in the Glick JV was $50.3 million and $50.0 million, respectively, as of September 30, 2023.

Discussion and Analysis of Results and Operations

Results of Operations

Net increase (decrease) in net assets resulting from operations includes net investment income, net realized gains (losses) and net unrealized appreciation (depreciation). Net investment income is the difference between our income from interest, dividends and fees and net expenses. Net realized gains (losses) is the difference between the proceeds received from dispositions of investment related assets and liabilities and their stated costs. Net unrealized appreciation (depreciation) is the net change in the fair value of our investment related assets and liabilities carried at fair value during the reporting period, including the reversal of previously recorded unrealized appreciation (depreciation) when gains or losses are realized.

Comparison of Three and Six Months ended March 31, 2024 and March 31, 2023

Total Investment Income

Total investment income includes interest on our investments, fee income and dividend income.

Total investment income for the three months ended March 31, 2024 and 2023 was $94.0 million and $96.3 million, respectively. For the three months ended March 31, 2024, this amount consisted of $90.1 million of interest income from portfolio investments (which included $4.8 million of PIK interest), $2.5 million of fee income and $1.4 million of dividend income. For the three months ended March 31, 2023, this amount consisted of $92.9 million of interest income from portfolio investments (which included $4.1 million of PIK interest), $2.4 million of fee income and $1.1 million of dividend income. The decrease of $2.3 million, or 2.4%, in our total investment income for the three months ended March 31, 2024, as compared to the three months ended March 31, 2023, was due primarily to a $2.8 million decrease in interest income, which resulted from purchase premium acceleration in connection with an exit, partially offset by a $0.4 million increase in dividend income and $0.2 million increase in fee income due to higher amendment fees.

Total investment income for the six months ended March 31, 2024 and 2023 was $192.0 million and $175.5 million, respectively. For the six months ended March 31, 2024, this amount consisted of $185.3 million of interest income from portfolio investments (which included $8.7 million of PIK interest), $3.9 million of fee income and $2.8 million of dividend income. For the six months ended March 31, 2023, this amount consisted of $169.0 million of interest income from portfolio investments (which included $10.3 million of PIK interest), $4.4 million of fee income and $2.1 million of dividend income. The increase of $16.5 million, or 9.4%, in our total investment income for the six months ended March 31, 2024, as compared to the six months ended March 31, 2023, was due primarily to a $16.4 million increase in interest income, which was primarily driven by the impact of higher base rates on our floating rate debt portfolio and a larger investment portfolio primarily from the assets acquired in the OSI2 Merger, and a $0.7 million increase in dividend income. This was partially offset by a $0.5 million decrease in fee income due to lower exit fees.

Expenses

Net expenses (expenses net of fee waivers) for the three months ended March 31, 2024 and 2023 were $52.7 million and $50.3 million, respectively. Net expenses increased for the three months ended March 31, 2024, as compared to the three months ended March 31, 2023, by $2.3 million, or 4.6%. The increase in net expenses was primarily driven by $4.1 million of higher interest expense due to the impact of rising interest rates on our floating rate liabilities. This was partially offset by $0.9 million of lower professional fees and $0.7 million of lower general and administrative expenses.

Net expenses (expenses net of fee waivers) for the six months ended March 31, 2024 and 2023 were $106.5 million and $90.6 million, respectively. Net expenses increased for the six months ended March 31, 2024, as compared to the six months ended March 31, 2023, by $15.8 million, or 17.5%. The increase in net expenses was primarily driven by $15.5 million of higher interest expense due to the impact of rising interest rates on our floating rate liabilities and an increase in average borrowings outstanding. Further contributing to the increase were $0.8 million of increased part I incentive fees as a result of higher adjusted net investment income and $1.2 million of higher management fees (net of waivers) as a result of a larger investment portfolio. This was partially offset by $0.9 million of lower professional fees and $0.9 million of lower general and administrative expenses.

Net Investment Income

Net investment income for the three months ended March 31, 2024 decreased by $4.6 million compared to the three months ended March 31, 2023, primarily as a result of the $2.3 million decrease in total investment income and the $2.3 million increase in net expenses.

90

Net investment income for the six months ended March 31, 2024 increased by $0.8 million compared to the six months ended March 31, 2023, primarily as a result of the $16.5 million increase in total investment income and the $15.8 million increase in net expenses.

Realized Gain (Loss)

Realized gains or losses are measured by the difference between the net proceeds from the sale or redemption of investments and foreign currency and the cost basis without regard to unrealized appreciation or depreciation previously recognized, and includes investments written-off during the period, net of recoveries. Realized losses may also be recorded in connection with our determination that certain investments are considered worthless securities and/or meet the conditions for loss recognition per the applicable tax rules.

During the three months ended March 31, 2024 and 2023, we recorded aggregate net realized losses of $6.6 million and $6.1 million, respectively, in connection with the exits and restructurings of various investments and foreign currency forward contracts. During the six months ended March 31, 2024 and 2023, we recorded aggregate net realized losses of $15.1 million and $9.3 million, respectively, in connection with the exits and restructurings of various investments and foreign currency forward contracts. See “Note 8. Realized Gains or Losses and Net Unrealized Appreciation or Depreciation” in the notes to the accompanying Consolidated Financial Statements for more details regarding investment realization events for the three and six months ended March 31, 2024 and 2023.

Net Unrealized Appreciation (Depreciation)

Net unrealized appreciation or depreciation is the net change in the fair value of our investments and foreign currency during the reporting period, including the reversal of previously recorded unrealized appreciation or depreciation when gains or losses are realized.

During the three months ended March 31, 2024 and 2023, we recorded net unrealized depreciation of $25.3 million and $18.3 million, respectively. For the three months ended March 31, 2024, this consisted of $24.8 million of net unrealized depreciation on equity investments and $13.5 million of net unrealized depreciation on debt investments, partially offset by $10.9 million of net unrealized appreciation related to exited investments (a portion of which resulted in a reclassification to realized losses) and $2.2 million of net unrealized appreciation of foreign currency forward contracts. For the three months ended March 31, 2023, this consisted of $24.5 million of net unrealized depreciation on debt investments and $4.9 million of net unrealized depreciation related to exited investments (a portion of which resulted in a reclassification to realized gains), partially offset by $9.5 million of net unrealized appreciation on equity investments and $1.6 million of net unrealized appreciation of foreign currency forward contracts.

During the six months ended March 31, 2024 and 2023, we recorded net unrealized depreciation of $50.3 million and $41.3 million, respectively. For the six months ended March 31, 2024, this consisted of $43.6 million of net unrealized depreciation on equity investments, $36.3 million of net unrealized depreciation on debt investments and $5.6 million of net unrealized depreciation of foreign currency forward contracts, partially offset by $35.3 million of net unrealized appreciation related to exited investments (a portion of which resulted in a reclassification to realized losses). For the six months ended March 31, 2023, this consisted of $44.0 million of net unrealized depreciation on debt investments and $9.4 million of net unrealized depreciation of foreign currency forward contracts, partially offset by $8.3 million of net unrealized appreciation on equity investments and $3.8 million of net unrealized appreciation related to exited investments (a portion of which resulted in a reclassification to realized losses).

Financial Condition, Liquidity and Capital Resources

We have a number of alternatives available to fund our investment portfolio and our operations, including raising equity, increasing or refinancing debt and funding from operational cash flow. We generally expect to fund the growth of our investment portfolio through additional debt and equity capital, which may include securitizing a portion of our investments. We cannot assure you, however, that our efforts to grow our portfolio will be successful. For example, our common stock has traded at prices below net asset value, and we may not be able to raise additional equity at prices below the then-current net asset value per share. We intend to continue to generate cash primarily from cash flows from operations, including interest earned, and future borrowings or equity offerings. We intend to fund our future distribution obligations through operating cash flow or with funds obtained through future equity and debt offerings or credit facilities, as we deem appropriate.

Our primary uses of cash are for (1) investments in portfolio companies and other investments to comply with certain portfolio diversification requirements, (2) the cost of operations (including our expenses, the management and incentive fees and any indemnification obligations), (3) debt service of borrowings and (4) cash distributions to stockholders. We may also from time to time repurchase or redeem some or all of our outstanding notes. At a special meeting of our stockholders held on

91

June 28, 2019, our stockholders approved the application of the reduced asset coverage requirements in Section 61(a)(2) of the Investment Company Act to us effective as of June 29, 2019. As a result of the reduced asset coverage requirement, we can incur $2 of debt for each $1 of equity as compared to $1 of debt for each $1 of equity. As of March 31, 2024, we had $1,680.7 million in senior securities and our asset coverage ratio was 188.04%. As of March 31, 2024, our target debt to equity ratio was 0.90x to 1.25x (i.e., one dollar of equity for each $0.90 to $1.25 of debt outstanding) and our net debt to equity ratio was 1.02x.

For the six months ended March 31, 2024, we experienced a net decrease in cash and cash equivalents (including restricted cash) of $8.0 million. During that period, net cash used in operating activities was $16.5 million, primarily from funding $733.5 million of investments, partially offset by $540.2 million of principal payments and sale proceeds received, the cash activities related to $85.6 million of net investment income, $85.1 million of net decreases in receivables and net increases in payables from unsettled transactions and a $13.6 million decrease in due from broker. During the same period, net cash provided by financing activities was $8.5 million, primarily consisting of $78.5 million of proceeds from the issuance of shares under the "at the market" offering and $20.0 million net borrowings under credit facilities, partially offset by $89.8 million of cash distributions paid to our stockholders.

For the six months ended March 31, 2023, we experienced a net increase in cash and cash equivalents (including restricted cash) of $26.6 million. During that period, net cash used in operating activities was $63.7 million, primarily from funding $362.0 million of investments and $36.7 million of net decrease in net payables from unsettled transactions and $22.3 million of cash received in connection with the OSI2 Merger, partially offset by $262.9 million of principal payments and sale proceeds received, the cash activities related to $84.8 million of net investment income and a $20.6 million decrease in due from portfolio companies. During the same period, net cash provided by financing activities was $90.8 million, primarily consisting of $190.0 million of net borrowings under the credit facilities, partially offset by $97.8 million of cash distributions paid to our stockholders.

As of March 31, 2024, we had $137.5 million in cash and cash equivalents (including $12.5 million of restricted cash), portfolio investments (at fair value) of $3.0 billion, $36.5 million of interest, dividends and fees receivable, $1.8 million of due from portfolio companies, $887.5 million of undrawn capacity on our credit facilities (subject to borrowing base and other limitations), $40.6 million of net payables from unsettled transactions, $730.0 million of borrowings outstanding under our credit facilities and $905.6 million of unsecured notes payable (net of unamortized financing costs, unaccreted discount and interest rate swap fair value adjustment).

As of September 30, 2023, we had $145.5 million in cash and cash equivalents (including $9.1 million of restricted cash), portfolio investments (at fair value) of $2.9 billion, $44.6 million of interest, dividends and fees receivable, $6.3 million of due from portfolio companies, $907.5 million of undrawn capacity on our credit facilities (subject to borrowing base and other limitations), $44.4 million of net receivables from unsettled transactions, $710.0 million of borrowings outstanding under our credit facilities and $890.7 million of unsecured notes payable (net of unamortized financing costs, unaccreted discount and interest rate swap fair value adjustment).

We may be a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financial needs of our portfolio companies. As of March 31, 2024, our only off-balance sheet arrangements consisted of $236.2 million of unfunded commitments, which was comprised of $209.1 million to provide debt and equity financing to certain of our portfolio companies and $27.1 million to provide financing to the JVs. Of the $209.1 million, approximately $179.0 million can be drawn immediately with the remaining amount subject to certain milestones that must be met by portfolio companies or other restrictions. As of September 30, 2023, our only off-balance sheet arrangements consisted of $232.7 million of unfunded commitments, which was comprised of $205.6 million to provide debt and equity financing to certain of our portfolio companies and $27.1 million to provide financing to the JVs. 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.

As of March 31, 2024, we have analyzed cash and cash equivalents, availability under our credit facilities, the ability to rotate out of certain assets and amounts of unfunded commitments that could be drawn and believe our liquidity and capital resources are sufficient to invest in market opportunities as they arise.

Indebtedness

See “Note 6. Borrowings” in the Consolidated Financial Statements for more details regarding our indebtedness.

Syndicated Facility

As of March 31, 2024, (i) the size of the our senior secured revolving credit facility, or, as amended and/or restated from time to time, the Syndicated Facility, pursuant to a senior secured revolving credit agreement, with the lenders, ING Capital LLC, as administrative agent, ING Capital LLC, JPMorgan Chase Bank, N.A., BofA Securities, Inc. and MUFG Union Bank, N.A. as joint lead arrangers and joint bookrunners, and JPMorgan Chase Bank, N.A. and Bank of America, N.A., as syndication agents, was $1.218 billion (with an “accordion” feature that permits us, under certain circumstances, to increase the size of the facility to up to the greater of $1.25 billion and our net worth (as defined in the Syndicated Facility) on the date of such increase), (ii) the period during which we may make drawings on $1.035 billion of commitments will expire on June 23, 2027 and the maturity date was June 23, 2028, (iii) the period during which we may make drawings with respect to the remaining commitments will expire on May 4, 2025 and the maturity date is May 4, 2026 and (iv) the interest rate margin for (a) SOFR loans (which may be 1- or 3-month, at our option) was 2.00% plus a SOFR adjustment which ranges between 0.11448% and 0.26161% and (b) alternate base rate loans was 1.00%.

Each loan or letter of credit originated or assumed under the Syndicated Facility is subject to the satisfaction of certain conditions. Borrowings under the Syndicated Facility are subject to the facility’s various covenants and the leverage restrictions

94

contained in the Investment Company Act. We cannot assure you that we will be able to borrow funds under the Syndicated Facility at any particular time or at all.

The following table describes significant financial covenants, as of March 31, 2024, with which we must comply under the Syndicated Facility on a quarterly basis:

Financial Covenant	Description	Target Value	December 31, 2023 Reported Value (1)
Minimum shareholders' equity	Net assets shall not be less than the sum of (x) $600 million, plus (y) 50% of the aggregate net proceeds of all sales of equity interests after May 6, 2020	$787 million	$1,512 million
Asset coverage ratio	Asset coverage ratio shall not be less than the greater of 1.50:1 and the statutory test applicable to us	1.50:1	1.89:1

Minimum net worth	Net worth shall not be less than $550 million	$550 million	$1,056 million

 ___________ 

(1) As contractually required, we report financial covenants based on the last filed quarterly or annual report, in this case our Quarterly Report on Form 10-Q for the quarter ended December 31, 2023. We were in compliance with all financial covenants under the Syndicated Facility based on the financial information contained in this Quarterly Report on Form 10-Q.

As of March 31, 2024 and September 30, 2023, we had $450.0 million and $430.0 million of borrowings outstanding under the Syndicated Facility, which had a fair value of $450.0 million and $430.0 million, respectively. Our borrowings under the Syndicated Facility bore interest at a weighted average interest rate of 7.579% and 6.255% for the six months ended March 31, 2024 and 2023, respectively. For the three and six months ended March 31, 2024, we recorded interest expense (inclusive of fees) of $9.6 million and $19.1 million, respectively, related to the Syndicated Facility. For the three and six months ended March 31, 2023, we recorded interest expense (inclusive of fees) of $13.1 million and $23.1 million, respectively, related to the Syndicated Facility.

Citibank Facility

On March 19, 2021, we became party to a revolving credit facility, or, as amended and/or restated from time to time, the Citibank Facility, with OCSL Senior Funding II LLC, our wholly-owned, special purpose financing subsidiary, as the borrower, us, as collateral manager and seller, each of the lenders from time to time party thereto, Citibank, N.A., as administrative agent, and Wells Fargo Bank, National Association, as collateral agent and custodian. On May 25, 2023, in connection with an amendment to the OSI2 Citibank Facility, the Citibank Facility was terminated.

Our borrowings under the Citibank Facility bore interest at a weighted average interest rate of 6.678% for the six months ended March 31, 2023. For the three and six months ended March 31, 2023, we recorded interest expense (inclusive of fees) of $2.9 million and $5.6 million, respectively, related to the Citibank Facility.

OSI2 Citibank Facility

On January 23, 2023, as a result of the consummation of the OSI2 Merger, we became party to a revolving credit facility, or, as amended and/or restated from time to time, the OSI2 Citibank Facility., with OSI 2 Senior Lending SPV, LLC, or OSI 2 SPV, our wholly-owned and consolidated subsidiary, as the borrower, us, as collateral manager, each of the lenders from time to time party thereto, Citibank, N.A., as administrative agent, and Deutsche Bank Trust Company Americas, as collateral agent.

As of March 31, 2024, we were able to borrow up to $400 million under the OSI2 Citibank Facility (subject to borrowing base and other limitations). As of March 31, 2024, the OSI2 Citibank Facility had a reinvestment period through May 25, 2025, during which advances may be made, and matures on January 26, 2027. Following the reinvestment period, OSI 2 SPV will be required to make certain mandatory amortization payments. Borrowings under the OSI2 Citibank Facility bear interest payable quarterly at a rate per year equal to (a) in the case of a lender that is identified as a conduit lender, the lesser of (i) the applicable commercial paper rate for such conduit lender and (ii) SOFR plus 2.00% per annum on broadly syndicated loans and 2.75% per annum on all other eligible loans and (b) for all other lenders under the OSI2 Citibank Facility, SOFR plus 2.00% per annum on broadly syndicated loans and 2.75% per annum on all other eligible loans, subject in all cases to a minimum overall rate of SOFR plus 2.50% per annum. After the reinvestment period, the applicable spread is 4.00% per year. There is also a non-usage fee of 0.50% per year on the unused portion of the OSI2 Citibank Facility, payable quarterly; provided that if the unused portion of the OSI2 Citibank Facility is greater than 30% of the commitments under the OSI2 Citibank Facility, the non-usage fee will be based on an unused portion of 30% of the commitments under the OSI2 Citibank Facility. The OSI2 Citibank Facility is secured by a first priority security interest in substantially all of OSI 2 SPV’s assets. As part of the OSI2 Citibank Facility, OSI 2 SPV is subject to certain limitations as to how borrowed funds may be used and the types of loans that are eligible to be acquired by OSI 2 SPV including restrictions on sector concentrations, loan size, tenor and minimum investment ratings (or estimated ratings). The OSI2 Citibank Facility also contains certain requirements relating to interest coverage,

95

collateral quality and portfolio performance, certain violations of which could result in the acceleration of the amounts due under the OSI2 Citibank Facility.

As of each of March 31, 2024 and September 30, 2023, we had $280.0 million outstanding under the OSI2 Citibank Facility, which had a fair value of $280.0 million. Our borrowings under the OSI2 Citibank Facility bore interest at a weighted average interest rate of 8.079% and 7.172% for the six months ended March 31, 2024 and the period from January 23, 2023 to March 31, 2023, respectively. For the three and six months ended March 31, 2024, we recorded interest expense (inclusive of fees) of $6.0 million and $12.1 million, respectively, related to the OSI2 Citibank Facility. For the period from January 23, 2023 to March 31, 2023, we recorded interest expense (inclusive of fees) of $3.1 million related to the OSI2 Citibank Facility.

2025 Notes

On February 25, 2020, we issued $300.0 million in aggregate principal amount of the 2025 Notes for net proceeds of $293.8 million after deducting OID of $2.5 million, underwriting commissions and discounts of $3.0 million and offering costs of $0.7 million. The OID on the 2025 Notes is amortized based on the effective interest method over the term of the notes.

2027 Notes

On May 18, 2021, we issued $350.0 million in aggregate principal amount of the 2027 Notes for net proceeds of $344.8 million after deducting OID of $1.0 million, underwriting commissions and discounts of $3.5 million and offering costs of $0.7 million. The OID on the 2027 Notes is amortized based on the effective interest method over the term of the notes.

In connection with the 2027 Notes, we entered into an interest rate swap to more closely align the interest rates of our liabilities with our investment portfolio, which consists of predominately floating rate loans. Under the interest rate swap agreement, we receive a fixed interest rate of 2.700% and pay a floating interest rate of the three-month SOFR plus 1.658% plus a SOFR adjustment of 0.26161% on a notional amount of $350.0 million. We designated the interest rate swap as the hedging instrument in an effective hedge accounting relationship.

2029 Notes

On August 15, 2023, we 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. The OID on the 2029 Notes is amortized based on the effective interest method over the term of the notes.

In connection with the 2029 Notes, we entered into an interest rate swap to more closely align the interest rates of its liabilities with its investment portfolio, which consists of predominately floating rate loans. Under the interest rate swap agreement, we receive a fixed interest rate of 7.100% and pays a floating interest rate of the three-month SOFR plus 3.1255% on a notional amount of $300.0 million. We designated the interest rate swap as the hedging instrument in an effective hedge accounting relationship. See Note 12 for more information regarding the interest rate swap.

Regulated Investment Company Status and Distributions

We have qualified and elected to be treated as a RIC under Subchapter M of the Code for U.S. federal income tax purposes. As long as we continue to qualify as a RIC, we will not be subject to tax on our investment company taxable income (determined without regard to any deduction for dividends paid) or realized net capital gains, to the extent that such taxable income or gains is distributed, or deemed to be distributed as dividends, to stockholders on a timely basis.

Taxable income generally differs from net income for financial reporting purposes due to temporary and permanent differences in the recognition of income and expenses, and generally excludes net unrealized appreciation or depreciation. Distributions declared and paid by us in a taxable year may differ from taxable income for that taxable year as such distributions may include the distribution of taxable income derived from the current taxable year or the distribution of taxable income derived from the prior taxable year carried forward into and distributed in the current taxable year. Distributions also may include returns of capital.

To maintain RIC tax treatment, we must, among other things, distribute (or be deemed to distribute) dividends, with respect to each taxable year, of an amount at least equal to 90% of our investment company taxable income (i.e., our net ordinary income and our realized net short-term capital gains in excess of realized net long-term capital losses, if any), determined without regard to any deduction for dividends paid. As a RIC, we are also subject to a federal excise tax, based on distribution requirements of our taxable income on a calendar year basis. We anticipate timely distribution of our taxable income in accordance with tax rules. We did not incur a U.S. federal excise tax for calendar year 2021. For the calendar year 2022, we incurred $0.1 million of excise tax. We did not incur a U.S. federal excise tax for calendar year 2023. We do not expect to incur a U.S. federal excise tax for calendar year 2024.

We intend to distribute at least 90% of our annual taxable income (which includes our taxable interest and fee income) to our stockholders. The covenants contained in our credit facilities may prohibit us from making distributions to our stockholders, and, as a result, could hinder our ability to satisfy the distribution requirement associated with our ability to be subject to tax as a RIC. In addition, we may retain for investment some or all of our net capital gains (i.e., realized net long-term capital gains in excess of realized net short-term capital losses) and treat such amounts as deemed distributions to our stockholders. If we do this, our stockholders will be treated as if they received actual distributions of the capital gains we retained and then reinvested the net after-tax proceeds in our common stock. Our stockholders also may be eligible to claim tax credits (or, in certain circumstances, tax refunds) equal to their allocable share of the tax we paid on the capital gains deemed distributed to them. To

97

the extent our taxable earnings for a fiscal and taxable year fall below the total amount of our dividend distributions for that fiscal and taxable year, a portion of those distributions may be deemed a return of capital to our stockholders.

We may not be able to achieve operating results that will allow us to make distributions at a specific level or to increase the amount of these distributions from time to time. In addition, we may be limited in our ability to make distributions due to the asset coverage test for borrowings applicable to us as a Business Development Company under the Investment Company Act and due to provisions in our credit facilities and debt instruments. If we do not distribute a certain percentage of our taxable income annually, we will suffer adverse tax consequences, including possible loss of our ability to be subject to tax as a RIC. We cannot assure stockholders that they will receive any distributions or distributions at a particular level.

A RIC may treat a distribution of its own stock as fulfilling its RIC distribution requirements if each stockholder elects to receive his or her entire distribution in either cash or stock of the RIC, subject to certain limitations regarding the aggregate amount of cash to be distributed to all stockholders. If these and certain other requirements are met, for U.S federal income tax purposes, the amount of the dividend paid in stock will be equal to the amount of cash that could have been received instead of stock.

We may generate qualified net interest income or qualified net short-term capital gains that may be exempt from U.S. withholding tax when distributed to foreign stockholders. A RIC is permitted to designate distributions of qualified net interest income and qualified short-term capital gains as exempt from U.S. withholding tax when paid to non-U.S. shareholders with proper documentation. The following table, which may be subject to change as we finalize our annual tax filings, lists the percentage of qualified net interest income and qualified short-term capital gains for the year ended September 30, 2023.

Year Ended	Qualified Net Interest Income		Qualified Short-Term Capital Gains
September 30, 2023	89.4	%	—

We have adopted a DRIP that provides for the reinvestment of any distributions that we declare in cash on behalf of our stockholders, unless a stockholder elects to receive cash. As a result, if our Board of Directors declares a cash distribution, then our stockholders who have not “opted out” of the DRIP will have their cash distributions automatically reinvested in additional shares of our common stock, rather than receiving a cash distribution. If our shares are trading at a premium to net asset value, we typically issue new shares to implement the DRIP, with such shares issued at the greater of the most recently computed net asset value per share of our common stock or 95% of the current market value per share of our common stock on the payment date for such distribution. If our shares are trading at a discount to net asset value, we typically purchase shares in the open market in connection with our obligations under the DRIP.

Related Party Transactions

We have entered into the Investment Advisory Agreement with Oaktree and the Administration Agreement with Oaktree Administrator, an affiliate of Oaktree. Mr. John B. Frank, an interested member of our Board of Directors, has an indirect pecuniary interest in Oaktree. Oaktree is a registered investment adviser under the Investment Advisers Act of 1940, as amended, that is partially and indirectly owned by Oaktree Capital Group, LLC. See “Note 10. Related Party Transactions – Investment Advisory Agreement” and “– Administrative Services” in the notes to the accompanying Consolidated Financial Statements.

Recent Developments

Distribution Declaration

On April 26, 2024, our Board of Directors declared a quarterly distribution of $0.55 per share, payable in cash on June 28, 2024 to stockholders of record on June 14, 2024.

Fee Waiver

On April 26, 2024, we and Oaktree entered into a letter agreement pursuant to which Oaktree waived additional base management fees such that the total amount of waived base management fees (including those waived in connection with the OSI2 Merger) will be $1.5 million for each of the three months ended March 31, 2024 and June 30, 2024. In addition, effective July 1, 2024, the base management fee will be calculated (net of base management fees previously waived by Oaktree) at an annual rate of 1.00% of total gross assets, including any investments made with borrowings, but excluding cash and cash equivalents.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

We are subject to financial market risks, including changes in the valuations of our investment portfolio and interest rates.

Valuation Risk

Our investments may not have a readily available market price, and we value these investments at fair value as determined by Oaktree, as our valuation designee. There is no single standard for determining fair value in good faith and valuation methodologies involve a significant degree of management judgment. In addition, our valuation methodology utilizes discount rates in part in valuing our investments, and changes in those discount rates may have an impact on the valuation of our investments. Accordingly, valuations by Oaktree do not necessarily represent the amounts which may eventually be realized from sales or other dispositions of investments. Estimated fair values may differ from the values that would have been used had a ready market for the investment existed, and the differences could be material to the financial statements.

Interest Rate Risk

We are subject to financial market risks, including changes in interest rates. Changes in interest rates may affect both our cost of funding and our interest income from portfolio investments, cash and cash equivalents and idle fund investments. Our risk management procedures are designed to identify and analyze our risk, to set appropriate policies and to continually monitor these risks. Our investment income will be affected by changes in various interest rates, including SOFR, EURIBOR, SONIA and prime rates, to the extent our debt investments include floating interest rates.

As of March 31, 2024, 85.4% of our debt investment portfolio (at fair value) and 85.8% of our debt investment portfolio (at cost) bore interest at floating rates. As of September 30, 2023, 86.2% of our debt investment portfolio (at fair value) and 86.4% of our debt investment portfolio (at cost) bore interest at floating rates. The composition of our floating rate debt investments by interest rate floor as of March 31, 2024 and September 30, 2023, was as follows: 

	March 31, 2024				September 30, 2023
($ in thousands)	Fair Value		% of Floating Rate Portfolio		Fair Value		% of Floating Rate Portfolio
0%	$	359,402	14.7	%	$	169,693	7.2	%
>0% and <1%	579,682		23.6	%	522,027		22.3	%

Total Floating Rate Investments	$	2,451,780	100.0	%	$	2,345,205	100.0	%

Based on our Consolidated Statement of Assets and Liabilities as of March 31, 2024, the following table shows the approximate annualized net increase (decrease) in net assets resulting from operations (excluding the impact of any potential incentive fees) of hypothetical base rate changes in interest rates, assuming no changes in our investment and capital structure. However, there can be no assurances our portfolio companies will be able to meet their contractual obligations at any or all levels on increases in interest rates.

We regularly measure exposure to interest rate risk. We assess interest rate risk and manage our interest rate exposure on an ongoing basis by comparing our interest rate sensitive assets to our interest rate sensitive liabilities. Based on this review, we determine whether or not any hedging transactions are necessary to mitigate exposure to changes in interest rates. The interest rate on the principal balance outstanding for primarily all floating rate loans is indexed to the SOFR and/or an alternate base rate, which typically resets semi-annually, quarterly, or monthly at the borrower's option. The borrower may also elect to have multiple interest reset periods for each loan. The following table shows a comparison of the interest rate base for our interest-bearing cash and outstanding investments, at principal, and our outstanding borrowings as of March 31, 2024 and September 30, 2023:

Item 4. Controls and Procedures

(a) Evaluation of Disclosure Controls and Procedures

Management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of March 31, 2024. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended, or the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the Securities and Exchange Commission’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its chief executive officer and chief financial officer, as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives. Based on the evaluation of our disclosure controls and procedures as of March 31, 2024, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective, at the reasonable assurance level, in timely identifying, recording, processing, summarizing and reporting any material information relating to us that is required to be disclosed in the reports we file or submit under the Exchange Act.

There were no changes in our internal control over financial reporting that occurred during the three months ended March 31, 2024 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

[15] Principal includes accumulated payment in kind ("PIK") interest and is net of repayments, if any. “£” signifies the investment is denominated in British Pounds. "€" signifies the investment is denominated in Euros. All other investments are denominated in U.S. dollars.

[16] The interest rate on the principal balance outstanding for most of the floating rate loans is indexed to the secured overnight financing rate ("SOFR"), the euro interbank offered rate ("EURIBOR" or "E"), the sterling overnight index average ("SONIA") and/or an alternate base rate (e.g., prime rate), which typically resets semi-annually, quarterly, or monthly at the borrower's option. The borrower may also elect to have multiple interest reset periods for each loan. For each of these loans, the Company has provided the applicable margin over the reference rate based on each respective credit agreement and the cash interest rate as of period end. As of March 31, 2024, the reference rates for the Company's variable rate loans were the 30-day SOFR at 5.33%, the 90-day SOFR at 5.31%, the 180-day SOFR at 5.23%, the PRIME at 8.50%, the SONIA at 5.19% and the 90-day EURIBOR at 3.88%. Most loans include an interest floor, which generally ranges from 0% to 2.75%. SOFR and SONIA based contracts may include a credit spread adjustment that is charged in addition to the base rate and the stated spread.

[17] Interest rates may be adjusted from period to period on certain term loans and revolvers. These rate adjustments may be either temporary in nature due to tier pricing arrangements or financial or payment covenant violations in the original credit agreements or permanent in nature per loan amendment or waiver documents.

Significant Accounting Policies

Basis of Presentation:

The Consolidated Financial Statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") and pursuant to the requirements for reporting on Form 10-Q and Regulation S-X. In the opinion of management, all adjustments of a normal recurring nature considered necessary for the fair presentation of the Consolidated Financial Statements have been made. All intercompany balances and transactions have been eliminated. The Company is an investment company following the accounting and reporting guidance in ASC Topic 946, Financial Services - Investment Companies ("ASC 946").

Use of Estimates:

The preparation of the financial statements in conformity with GAAP requires management to make certain estimates and assumptions affecting amounts reported in the financial statements and accompanying notes. These estimates are based on the information that is currently available to the Company and on various other assumptions that the Company believes to be reasonable under the circumstances. Changes in the economic and political environments, financial markets and any other parameters used in determining these estimates could cause actual results to differ and such differences could be material. Significant estimates include the valuation of investments and revenue recognition.

Consolidation:

The accompanying Consolidated Financial Statements include the accounts of Oaktree Specialty Lending Corporation and its consolidated subsidiaries. Each consolidated subsidiary is wholly-owned and, as such, consolidated into the Consolidated Financial Statements. Certain subsidiaries that hold investments are treated as pass through entities for U.S. federal income tax purposes. The assets of certain of the consolidated subsidiaries are not directly available to satisfy the claims of the creditors of Oaktree Specialty Lending Corporation or any of its other subsidiaries.

As an investment company, portfolio investments held by the Company are not consolidated into the Consolidated Financial Statements but rather are included on the Statements of Assets and Liabilities as investments at fair value.

Fair Value Measurements:

Oaktree, as the valuation designee of the Company's Board of Directors pursuant to Rule 2a-5 under the Investment Company Act, determines the fair value of our assets on at least a quarterly basis in accordance with ASC 820. ASC 820 defines fair value as the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. A liability's fair value is defined as the amount that would be paid to transfer the liability to a new obligor, not the amount that would be paid to settle the liability with the creditor. ASC 820 prioritizes the use of observable market prices over entity-specific inputs. Where observable prices or inputs are not available or reliable, valuation techniques are applied. These valuation techniques involve some level of management estimation and judgment, the degree of which is dependent on the price transparency for the investments or market and the investments' complexity.

Hierarchical levels, defined by ASC 820 and directly related to the amount of subjectivity associated with the inputs to fair valuation of these assets and liabilities, are as follows:

•Level 1 — Unadjusted, quoted prices in active markets for identical assets or liabilities as of the measurement date.

•Level 2 — Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data at the measurement date for substantially the full term of the assets or liabilities.

•Level 3 — Unobservable inputs that reflect Oaktree's best estimate of what market participants would use in pricing the asset or liability at the measurement date. Consideration is given to the risk inherent in the valuation technique and the risk inherent in the inputs to the model.

If inputs used to measure fair value fall into different levels of the fair value hierarchy, an investment's level is based on the lowest level of input that is significant to the fair value measurement. Oaktree's assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the investment.

This includes investment securities that are valued using "bid" and "ask" prices obtained from independent third party pricing services or directly from brokers. These investments may be classified as Level 3 because the quoted prices may be indicative in nature for securities that are in an inactive market, may be for similar securities or may require adjustments for investment-specific factors or restrictions.

Financial instruments with readily available quoted prices generally will have a higher degree of market price observability and a lesser degree of judgment inherent in measuring fair value. As such, Oaktree obtains and analyzes readily available market quotations provided by pricing vendors and brokers for all of the Company's investments for which quotations are available. In determining the fair value of a particular investment, pricing vendors and brokers use observable market information, including both binding and non-binding indicative quotations.

Oaktree seeks to obtain at least two quotations for the subject or similar securities, typically from pricing vendors. If Oaktree is unable to obtain two quotes from pricing vendors, or if the prices obtained from pricing vendors are not within Oaktree's set threshold, Oaktree seeks to obtain a quote directly from a broker making a market for the asset. Oaktree evaluates the quotations provided by pricing vendors and brokers based on available market information, including trading activity of the subject or similar securities, or by performing a comparable security analysis to ensure that fair values are reasonably estimated. Oaktree also performs back-testing of valuation information obtained from pricing vendors and brokers against actual prices received in transactions. In addition to ongoing monitoring and back-testing, Oaktree performs due diligence procedures over pricing vendors to understand their methodology and controls to support their use in the valuation process. Generally, Oaktree does not adjust any of the prices received from these sources.

If the quotations obtained from pricing vendors or brokers are determined to not be reliable or are not readily available, Oaktree values such investments using any of three different valuation techniques. The first valuation technique is the transaction precedent technique, which utilizes recent or expected future transactions of the investment to determine fair value, to the extent applicable. The second valuation technique is an analysis of the enterprise value ("EV") of the portfolio company. EV means the entire value of the portfolio company to a market participant, including the sum of the values of debt and equity securities used to capitalize the enterprise at a point in time. The EV analysis is typically performed to determine (i) the value of equity investments, (ii) whether there is credit impairment for debt investments and (iii) the value for debt investments that the Company is deemed to control under the Investment Company Act. To estimate the EV of a portfolio company, Oaktree analyzes various factors, including the portfolio company’s historical and projected financial results, macroeconomic impacts on the company and competitive dynamics in the company’s industry. Oaktree also utilizes some or all of the following information based on the individual circumstances of the portfolio company: (i) valuations of comparable public companies, (ii) recent sales of private and public comparable companies in similar industries or having similar business or earnings characteristics, (iii) purchase prices as a multiple of their earnings or cash flow, (iv) the portfolio company’s ability to meet its forecasts and its business prospects, (v) a discounted cash flow analysis, (vi) estimated liquidation or collateral value of the portfolio company's assets and (vii) offers from third parties to buy the portfolio company. Oaktree may probability weight potential sale outcomes with respect to a portfolio company when uncertainty exists as of the valuation date. The third valuation technique is a market yield technique, which is typically performed for non-credit impaired debt investments. In the market yield technique, a current price is imputed for the investment based upon an assessment of the expected market yield for a similarly structured investment with a similar level of risk, and Oaktree considers the current contractual interest rate, the capital structure and other terms of the investment relative to risk of the company and the specific investment. A key determinant of risk, among other things, is the leverage through the investment relative to the EV of the portfolio company. As debt investments held by the Company are substantially illiquid with no active transaction market, Oaktree depends on primary market data, including newly funded transactions and industry specific market movements, as well as secondary market data with respect to high yield debt instruments and syndicated loans, as inputs in determining the appropriate market yield, as applicable.

In accordance with ASC 820-10, certain investments that qualify as investment companies in accordance with ASC 946 may be valued using net asset value as a practical expedient for fair value. Consistent with FASB guidance under ASC 820, these investments are excluded from the hierarchical levels. These investments are generally not redeemable.

Oaktree estimates the fair value of certain privately held warrants using a Black Scholes pricing model, which includes an analysis of various factors and subjective assumptions, including the current stock price (by using an EV analysis as described above), the expected period until exercise, expected volatility of the underlying stock price, expected dividends and the risk free rate. Changes in the subjective input assumptions can materially affect the fair value estimates.

Rule 2a-5 under the Investment Company Act permits boards of directors of registered investment companies and Business Development Companies to either (i) choose to determine fair value in good faith or (ii) designate a valuation designee tasked with determining fair value in good faith, subject to the board’s oversight. The Company's Board of Directors has designated Oaktree to serve as its valuation designee effective September 8, 2022.

Oaktree undertakes a multi-step valuation process each quarter in connection with determining the fair value of the Company's investments:

•The quarterly valuation process begins with each portfolio company or investment being initially valued by Oaktree's valuation team;

•Preliminary valuations are then reviewed and discussed with management of Oaktree;

•Separately, independent valuation firms prepare valuations of the Company's investments, on a selected basis, for which market quotations are not readily available or are readily available but deemed not reflective of the fair value of the investment, and submit the reports to the Company and provide such reports to Oaktree;

•Oaktree compares and contrasts its preliminary valuations to the valuations of the independent valuation firms and prepares a valuation report for the Audit Committee;

•The Audit Committee reviews the valuation report with Oaktree, and Oaktree responds and supplements the valuation report to reflect any discussions between Oaktree and the Audit Committee; and

•Oaktree, as valuation designee, determines the fair value of each investment in the Company's portfolio.

The fair value of the Company's investments as of March 31, 2024 and September 30, 2023 was determined by Oaktree, as the Company's valuation designee. The Company has and will continue to engage independent valuation firms to provide assistance regarding the determination of the fair value of a portion of its portfolio securities for which market quotations are not readily available or are readily available but deemed not reflective of the fair value of the investment each quarter.

Due to the inherent uncertainty of determining the fair value of investments that do not have a readily available market value, the fair value of the Company’s investments may fluctuate from period to period. Because of the inherent uncertainty of valuation, these estimated values may differ significantly from the values that would have been reported had a ready market for the investments existed, and it is reasonably possible that the difference could be material.

With the exception of the line items entitled "deferred financing costs," "deferred offering costs," "other assets," "deferred tax liability," "credit facilities payable" and "unsecured notes payable," which are reported at amortized cost, all assets and liabilities approximate fair value on the Consolidated Statements of Assets and Liabilities. The carrying value of the line items titled "interest, dividends and fees receivable," "due from portfolio companies," "receivables from unsettled transactions," "due from broker," "accounts payable, accrued expenses and other liabilities," "base management fee and incentive fee payable," "due to affiliate," "interest payable" and "payables from unsettled transactions" approximate fair value due to their short maturities.

Foreign Currency Translation:

The accounting records of the Company are maintained in U.S. dollars. All assets and liabilities denominated in foreign currencies are translated into U.S. dollars based on the prevailing foreign exchange rate on the reporting date. The Company does not isolate that portion of the results of operations resulting from changes in foreign exchange rates on investments from the fluctuations arising from changes in market prices of securities held. The Company’s investments in foreign securities may involve certain risks, including foreign exchange restrictions, expropriation, taxation or other political, social or economic risks, all of which could affect the market and/or credit risk of the investment. In addition, changes in the relationship of foreign currencies to the U.S. dollar can significantly affect the value of these investments and therefore the earnings of the Company.

Derivative Instruments:

Foreign Currency Forward Contracts

The Company uses foreign currency forward contracts to reduce the Company's exposure to fluctuations in the value of foreign currencies. In a foreign currency forward contract, the Company agrees to receive or deliver a fixed quantity of one currency for another at a pre-determined price at a future date. Foreign currency forward contracts are marked-to-market at the applicable forward rate. Unrealized appreciation (depreciation) on foreign currency forward contracts is recorded within derivative assets or derivative liabilities on the Consolidated Statements of Assets and Liabilities by counterparty on a net basis, not taking into account collateral posted which is recorded separately, if applicable. Purchases and settlements of foreign currency forward contracts having the same settlement date and counterparty are generally settled net and any realized gains or losses are recognized on the settlement date. The Company does not utilize hedge accounting with respect to foreign currency forward contracts and, as such, the Company recognizes its foreign currency forward contracts at fair value with changes included in the net unrealized appreciation (depreciation) on the Consolidated Statements of Operations.

Interest Rate Swaps

The Company uses interest rate swaps to hedge some of the Company's fixed rate debt. The Company designated the interest rate swaps as the hedging instruments in an effective hedge accounting relationship, and therefore the periodic payments are recognized as components of interest expense in the Consolidated Statements of Operations. Depending on the nature of the balance at period end, the fair value of each interest rate swap is either included as a derivative asset or derivative liability on the Company's Consolidated Statements of Assets and Liabilities. The change in fair value of the interest rate swaps is offset by a change in the carrying value of the fixed rate debt. Any amounts paid to the counterparty to cover collateral obligations under the terms of the interest rate swap agreements are included in due from broker on the Company's Consolidated Statements of Assets and Liabilities.

Investment Income:

Interest Income

Interest income, adjusted for accretion of original issue discount ("OID"), is recorded on an accrual basis to the extent that such amounts are expected to be collected. The Company stops accruing interest on investments when it is determined that interest is no longer collectible. Investments that are expected to pay regularly scheduled interest in cash are generally placed on non-accrual status when there is reasonable doubt that principal or interest cash payments will be collected. Cash interest payments received on investments may be recognized as income or a return of capital depending upon management’s judgment. A non-accrual investment is restored to accrual status if past due principal and interest are paid in cash and the portfolio company, in management’s judgment, is likely to continue timely payment of its remaining obligations. As of March 31, 2024, there were five investments on non-accrual status that in aggregate represented 4.3% and 2.4% of total debt investments at cost and fair value, respectively. As of September 30, 2023, there were four investments on non-accrual status that in aggregate represented 2.4% and 1.8% of total debt investments at cost and fair value, respectively.

In connection with its investment in a portfolio company, the Company sometimes receives nominal cost equity that is valued as part of the negotiation process with the portfolio company. When the Company receives nominal cost equity, the Company allocates its cost basis in the investment between debt securities and the nominal cost equity at the time of origination. Any resulting discount from recording the loan, or otherwise purchasing a security at a discount, is accreted into interest income over the life of the loan.

PIK Interest Income

The Company's investments in debt securities may contain PIK interest provisions. PIK interest, which generally represents contractually deferred interest added to the loan balance that is generally due at the end of the loan term, is generally recorded on the accrual basis to the extent such amounts are expected to be collected. The Company generally ceases accruing PIK interest if there is insufficient value to support the accrual or if the Company does not expect the portfolio company to be able to pay all principal and interest due. The Company's decision to cease accruing PIK interest on a loan or debt security involves subjective judgments and determinations based on available information about a particular portfolio company, including whether the portfolio company is current with respect to its payment of principal and interest on its loans and debt securities; financial statements and financial projections for the portfolio company; the Company's assessment of the portfolio company's business development success; information obtained by the Company in connection with periodic formal update interviews with the portfolio company's management and, if appropriate, the private equity sponsor; and information about the general economic and market conditions in which the portfolio company operates. The Company's determination to cease accruing PIK interest is generally made well before the Company's full write-down of a loan or debt security. In addition, if it is subsequently determined that the Company will not be able to collect any previously accrued PIK interest, the fair value of the loans or debt securities would be reduced by the amount of such previously accrued, but uncollectible, PIK interest. The accrual of PIK interest on the Company’s debt investments increases the recorded cost basis of these investments in the Consolidated Financial Statements including for purposes of computing the capital gains incentive fee payable by the Company to Oaktree. To maintain its status as a RIC, certain income from PIK interest may be required to be distributed to the Company’s stockholders, even though the Company has not yet collected the cash and may never do so.

Fee Income

Oaktree or its affiliates may provide financial advisory services to portfolio companies and, in return, the Company may receive fees for capital structuring services. These fees are generally non-recurring and are recognized by the Company upon the investment closing date. The Company may also receive additional fees in the ordinary course of business, including servicing, amendment, exit and prepayment fees, which are classified as fee income and recognized as they are earned or the services are rendered.

Dividend Income

The Company generally recognizes dividend income on the ex-dividend date for public securities and the record date for private equity investments. Distributions received from private equity investments are evaluated to determine if the distribution should be recorded as dividend income or a return of capital. Generally, the Company will not record distributions from private equity investments as dividend income unless there are sufficient earnings at the portfolio company prior to the distribution. Distributions that are classified as a return of capital are recorded as a reduction in the cost basis of the investment.

Cash and Cash Equivalents and Restricted Cash:

Cash and cash equivalents consist of demand deposits and highly liquid investments with maturities of three months or less when acquired. The Company places its cash and cash equivalents and restricted cash with financial institutions and, at times, cash held in bank accounts exceeds the Federal Deposit Insurance Corporation ("FDIC") insurance limit. Cash and cash equivalents are included on the Company's Consolidated Schedule of Investments and cash equivalents are classified as Level 1 assets.

As of March 31, 2024, included in restricted cash was $12.5 million that was held at Deutsche Bank Trust Company Americas in connection with the OSI2 Citibank Facility (as defined in Note 6. Borrowings). Pursuant to the terms of the OSI2 Citibank Facility, the Company was restricted in terms of access to the $12.5 million until the occurrence of the periodic distribution dates and, in connection therewith, the Company’s submission of its required periodic reporting schedules and verifications of the Company’s compliance with the terms of the OSI2 Citibank Facility. As of September 30, 2023, included in restricted cash was $9.1 million that was held at Deutsche Bank Trust Company Americas in connection with the OSI2 Citibank Facility.

Due from Portfolio Companies:

Due from portfolio companies consists of amounts payable to the Company from its portfolio companies, including proceeds from the sale of portfolio companies not yet received or being held in escrow and excluding those amounts attributable to interest, dividends or fees receivable. These amounts are recognized as they become payable to the Company (e.g., principal payments on the scheduled amortization payment date).

Receivables/Payables from Unsettled Transactions:

Receivables/payables from unsettled transactions consist of amounts receivable to or payable by the Company for transactions that have not settled at the reporting date.

Deferred Financing Costs:

Deferred financing costs consist of fees and expenses paid in connection with the closing or amending of credit facilities and debt offerings. Deferred financing costs in connection with credit facilities are capitalized as an asset when incurred. Deferred financing costs in connection with all other debt arrangements are a direct deduction from the related debt liability when incurred. Deferred financing costs are amortized using the effective interest method over the term of the respective debt arrangement. This amortization expense is included in interest expense in the Consolidated Statements of Operations. Upon early termination or modification of a credit facility, all or a portion of unamortized fees related to such facility may be accelerated into interest expense. For extinguishments of the Company’s unsecured notes payable, any unamortized deferred financing costs are deducted from the carrying amount of the debt in determining the gain or loss from the extinguishment.

Deferred Offering Costs:

Legal fees and other costs incurred in connection with the Company’s shelf registration statement are capitalized as deferred offering costs in the Consolidated Statements of Assets and Liabilities. To the extent any such costs relate to equity offerings, these costs are charged as a reduction of capital upon utilization. To the extent any such costs relate to debt offerings, these costs are treated as deferred financing costs and are amortized over the term of the respective debt arrangement. Any

deferred offering costs that remain at the expiration of the shelf registration statement or when it becomes probable that an offering will not be completed are expensed.

Income Taxes:

The Company has elected to be subject to tax as a RIC under Subchapter M of the Code and operates in a manner so as to qualify for the tax treatment applicable to RICs. In order to be subject to tax as a RIC, among other things, the Company is required to meet certain source of income and asset diversification requirements and timely distribute dividends to its stockholders of an amount generally at least equal to 90% of investment company taxable income, as defined by the Code and determined without regard to any deduction for dividends paid, for each taxable year. As a RIC, the Company is not subject to U.S. federal income tax on the portion of its taxable income and gains distributed currently to stockholders as a dividend. Depending on the level of taxable income earned during a taxable year, the Company may choose to retain taxable income in excess of current year dividend distributions and would distribute such taxable income in the next taxable year. The Company would then incur a 4% excise tax on such income, as required. To the extent that the Company determines that its estimated current year annual taxable income, determined on a calendar year basis, could exceed estimated current calendar year dividend distributions, the Company accrues excise tax, if any, on estimated excess taxable income as taxable income is earned. The Company anticipates timely distribution of its taxable income within the tax rules under Subchapter M of the Code. For calendar year 2022, the Company incurred $0.1 million of excise tax. The Company did not incur any U.S. federal excise tax for calendar year 2023. The Company does not expect to incur a U.S. federal excise tax for calendar year 2024.

The Company holds certain portfolio investments through taxable subsidiaries. The purpose of the Company's taxable subsidiaries is to permit the Company to hold equity investments in portfolio companies which are "pass through" entities for U.S. federal income tax purposes in order to comply with the RIC tax requirements. The taxable subsidiaries are consolidated for financial reporting purposes, and portfolio investments held by them are included in the Company’s Consolidated Financial Statements as portfolio investments and recorded at fair value. The taxable subsidiaries are not consolidated with the Company for U.S. federal income tax purposes and may generate income tax expense, or benefit, and the related tax assets and liabilities, as a result of their ownership of certain portfolio investments. This income tax expense, if any, would be reflected in the Company's Consolidated Statements of Operations. The Company uses the liability method to account for its taxable subsidiaries' income taxes. Using this method, the Company recognizes deferred tax assets and liabilities for the estimated future tax effects attributable to temporary differences between financial reporting and tax bases of assets and liabilities. In addition, the Company recognizes deferred tax benefits associated with net operating loss carry forwards that it may use to offset future tax obligations. The Company measures deferred tax assets and liabilities using the enacted tax rates expected to apply to taxable income in the years in which it expects to recover or settle those temporary differences.

FASB ASC Topic 740, Accounting for Uncertainty in Income Taxes ("ASC 740"), provides guidance for how uncertain tax positions should be recognized, measured, presented and disclosed in the Company's Consolidated Financial Statements. ASC 740 requires the evaluation of tax positions taken or expected to be taken in the course of preparing the Company's tax returns to determine whether the tax positions are "more-likely-than-not" of being sustained by the applicable tax authority. Tax positions not deemed to meet the more-likely-than-not threshold are recorded as a tax benefit or expense in the current year. Management's determinations regarding ASC 740 may be subject to review and adjustment at a later date based upon factors including an ongoing analysis of tax laws, regulations and interpretations thereof. The Company recognizes the tax benefits of uncertain tax positions only where the position is "more-likely-than-not" to be sustained assuming examination by tax authorities. Management has analyzed the Company's tax positions and has concluded that no liability for unrecognized tax benefits should be recorded related to uncertain tax positions taken on returns filed for open tax years 2021, 2022 and 2023. The Company identifies its major tax jurisdictions as U.S. Federal and California, and the Company is not aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will change materially in the next 12 months.

Recently Adopted Accounting Pronouncements

In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting (Topic 280), which improves reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The amendments are effective for fiscal years beginning after December 15, 2023 and interim period within fiscal years beginning after December 15, 2024. The Company does not expect this guidance to materially impact its consolidated financial statements.

(a)In accordance with ASC 820-10, certain investments that are measured using the net asset value per share (or its equivalent) as a practical expedient for fair value have not been classified in the fair value hierarchy. These investments are generally not redeemable. The fair value amounts presented in this table are intended to permit reconciliation of the fair value hierarchy to the amounts presented in the Consolidated Statements of Assets and Liabilities.

The following table presents the financial instruments carried at fair value as of September 30, 2023 on the Company's Consolidated Statement of Assets and Liabilities for each of the three levels of hierarchy established by ASC 820:

__________ 

(a)In accordance with ASC 820-10, certain investments that are measured using the net asset value per share (or its equivalent) as a practical expedient for fair value have not been classified in the fair value hierarchy. These investments are generally not redeemable. The fair value amounts presented in this table are intended to permit reconciliation of the fair value hierarchy to the amounts presented in the Consolidated Statements of Assets and Liabilities.

When a determination is made to classify a financial instrument within Level 3 of the valuation hierarchy, the determination is based upon the fact that the unobservable factors are significant to the overall fair value measurement. However, Level 3 financial instruments typically have both unobservable or Level 3 components and observable components (i.e. components that are actively quoted and can be validated by external sources). Accordingly, the appreciation (depreciation) in the tables below includes changes in fair value due in part to observable factors that are part of the valuation methodology. Transfers between levels are recognized at the beginning of the reporting period.

The following table provides a roll-forward in the changes in fair value from December 31, 2023 to March 31, 2024 for all investments for which Oaktree determined fair value using unobservable (Level 3) factors:

__________ 

(a)Weighted averages are calculated based on fair value of investments.

(b)Used when market participants would take into account market yield when pricing the investment.

(c)Used when market participants would use such multiples when pricing the investment.

(d)Used when there is an observable transaction or pending event for the investment.

(e)Oaktree generally uses prices provided by an independent pricing service which are non-binding indicative prices on or near the valuation date as the primary basis for the fair value determinations for quoted senior secured debt investments. Since these prices are non-binding, they may not be indicative of fair value. Oaktree evaluates the quotations provided by pricing vendors and brokers based on available market information, including trading activity of the subject or similar securities, or by performing a comparable security analysis to ensure that fair values are reasonably estimated.

(f)Oaktree determined the value of its subordinated notes of each JV based on the total assets less the total liabilities senior to the subordinated notes held at such JV in an amount not exceeding par under the EV technique.

The following table provides quantitative information related to the significant unobservable inputs for Level 3 investments, which are carried at fair value, as of September 30, 2023:

(e)Oaktree generally uses prices provided by an independent pricing service which are non-binding indicative prices on or near the valuation date as the primary basis for the fair value determinations for quoted senior secured debt investments. Since these prices are non-binding, they may not be indicative of fair value. Oaktree evaluates the quotations provided by pricing vendors and brokers based on available market information, including trading activity of the subject or similar securities, or by performing a comparable security analysis to ensure that fair values are reasonably estimated.

(f)Oaktree determined the value of its subordinated notes of each JV based on the total assets less the total liabilities senior to the subordinated notes held at such JV in an amount not exceeding par under the EV technique.

Under the market yield technique, the significant unobservable input used in the fair value measurement of the Company's investments in debt securities is the market yield. Increases or decreases in the market yield may result in a lower or higher fair value measurement, respectively.

Under the EV technique, the significant unobservable input used in the fair value measurement of the Company's investments in debt or equity securities is the earnings before interest, taxes, depreciation and amortization ("EBITDA"), revenue or asset multiple, as applicable. Increases or decreases in the valuation multiples in isolation may result in a higher or lower fair value measurement, respectively.

(1)This industry includes the Company's investments in the JVs and CLOs.

As of March 31, 2024 and September 30, 2023, the Company had no single investment that represented greater than 10% of the total investment portfolio at fair value. Income, consisting of interest, dividends, fees, other investment income and realization of gains or losses, may fluctuate and in any given period can be highly concentrated among several investments.

Senior Loan Fund JV I, LLC

In May 2014, the Company entered into an LLC agreement with Kemper to form SLF JV I. The Company co-invests in senior secured loans of middle-market companies and other corporate debt securities with Kemper through its investment in SLF JV I. SLF JV I is managed by a four person Board of Directors, two of whom are selected by the Company and two of whom are selected by Kemper. All portfolio decisions and investment decisions in respect of SLF JV I must be approved by the SLF JV I investment committee, which consists of one representative selected by the Company and one representative selected by Kemper (with approval from a representative of each required). Since the Company does not have a controlling financial interest in SLF JV I, the Company does not consolidate SLF JV I.

SLF JV I is capitalized pro rata with LLC equity interests as transactions are completed and may be capitalized with additional subordinated notes issued to the Company and Kemper by SLF JV I. The subordinated notes issued by SLF JV I (the "SLF JV I Notes") are senior in right of payment to SLF JV I LLC equity interests and subordinated in right of payment to SLF JV I’s secured debt. As of March 31, 2024 and September 30, 2023, the Company and Kemper owned, in the aggregate, 87.5% and 12.5%, respectively, of the LLC equity interests of SLF JV I and the outstanding SLF JV I Notes. SLF JV I is not an "eligible portfolio company" as defined in section 2(a)(46) of the Investment Company Act.

SLF JV I has a revolving credit facility with Bank of America, N.A. (the "SLF JV I Facility"), which permitted up to $270.0 million of borrowings (subject to borrowing base and other limitations) as of March 31, 2024. Borrowings under the SLF JV I Facility are secured by all of the assets of SLF JV I Funding II LLC, a special purpose financing subsidiary of SLF JV I. As of March 31, 2024, the revolving period of the SLF JV I Facility was scheduled to expire August 12, 2026 and the maturity date was August 17, 2026. As of March 31, 2024, borrowings under the SLF JV I Facility accrued interest at a rate equal to daily SOFR plus 2.00% per annum. As of March 31, 2024 and September 30, 2023, $190.0 million and $149.0 million of borrowings were outstanding under the SLF JV I Facility, respectively.

As of March 31, 2024 and September 30, 2023, SLF JV I had total assets of $398.7 million and $376.1 million, respectively. SLF JV I's portfolio primarily consisted of senior secured loans to 54 and 48 portfolio companies as of March 31, 2024 and September 30, 2023, respectively. The portfolio companies in SLF JV I are in industries similar to those in which the Company may invest directly. As of March 31, 2024, the Company's investment in SLF JV I consisted of LLC equity interests and SLF JV I Notes of $142.3 million in aggregate, at fair value. As of September 30, 2023, the Company's investment in SLF JV I consisted of LLC equity interests and SLF JV I Notes of $141.5 million in aggregate, at fair value.

As of each of March 31, 2024 and September 30, 2023, the Company and Kemper had funded approximately $190.5 million to SLF JV I, of which $166.7 million was from the Company. As of each of March 31, 2024 and September 30, 2023, the Company had aggregate commitments to fund SLF JV I of $13.1 million, of which approximately $9.8 million was to fund additional SLF JV I Notes and approximately $3.3 million was to fund LLC equity interests in SLF JV I.

Below is a summary of SLF JV I's portfolio, followed by a listing of the individual loans in SLF JV I's portfolio as of March 31, 2024 and September 30, 2023:

OCSI Glick JV LLC

On March 19, 2021, the Company became party to the LLC agreement of Glick JV. The Company co-invests primarily in senior secured loans of middle-market companies with GF Equity Funding through the Glick JV. The Glick JV is managed by a four person Board of Directors, two of whom are selected by the Company and two of whom are selected by GF Equity Funding. The Glick JV is capitalized as transactions are completed, and portfolio decisions and investment decisions in respect of the Glick JV must be approved by the Glick JV investment committee, which consists of one representative selected by the Company and one representative selected by GF Equity Funding (with approval from a representative of each required). Since the Company does not have a controlling financial interest in the Glick JV, the Company does not consolidate the Glick JV.

The members provide capital to the Glick JV in exchange for LLC equity interests, and the Company and GF Debt Funding 2014 LLC ("GF Debt Funding"), an entity advised by affiliates of GF Equity Funding, provide capital to the Glick JV in exchange for subordinated notes issued by the Glick JV (the "Glick JV Notes").

(the "Glick JV Facility"), which, as of March 31, 2024, had a revolving period end date and maturity date of August 12, 2026 and August 17, 2026, respectively, and permitted borrowings of up to $80.0 million (subject to borrowing base and other limitations). Borrowings under the Glick JV Facility are secured by all of the assets of OCSL Glick JV Funding II LLC, a special purpose financing subsidiary of the Glick JV. As of March 31, 2024, borrowings under the Glick JV Facility bore interest at a rate equal to daily SOFR plus 2.00% per annum. $74.0 million and $53.0 million of borrowings were outstanding under the Glick JV Deutsche Bank Facility as of March 31, 2024 and September 30, 2023, respectively.

The Glick JV Notes are junior in right of payment to the repayment of temporary contributions made by the Company to fund investments of the Glick JV that are repaid when GF Equity Funding and GF Debt Funding make their capital contributions and fund their Glick JV Notes, respectively.

The borrower may also elect to have multiple interest reset periods for each loan. For each of these loans, the Company has provided the applicable margin over the reference rates based on each respective credit agreement and the cash interest rate as of period end. As of March 31, 2024, the reference rates for the Glick JV's variable rate loans were the 30-day SOFR

at 5.33% and the 90-day SOFR at 5.31%. Most loans include an interest floor, which generally ranges from 0% to 1%. SOFR based contracts may include a credit spread adjustment that is charged in addition to the base rate and the stated spread.

(3) Represents the current determination of fair value as of March 31, 2024 utilizing a similar technique as the Company in accordance with ASC 820. However, the determination of such fair value is not included in the valuation process described elsewhere herein.

Distributions

Distributions to common stockholders are recorded on the ex-dividend date. The amount to be paid out as a dividend is determined by the Board of Directors and is based on management’s estimate of the Company’s annual taxable income. Net realized capital gains, if any, may be distributed to stockholders or retained for reinvestment.

The Company has adopted a dividend reinvestment plan (“DRIP”) that provides for reinvestment of any distributions the Company declares in cash on behalf of its stockholders, unless a stockholder elects to receive cash. As a result, if the Company’s Board of Directors declares a cash distribution, then the Company’s stockholders who have not “opted out” of the Company’s DRIP will have their cash distribution automatically reinvested in additional shares of the Company’s common stock, rather than receiving the cash distribution. If the Company’s shares are trading at a premium to net asset value, the Company typically issues new shares to implement the DRIP with such shares issued at the greater of the most recently computed net asset value per share of common stock or 95% of the current market price per share of common stock on the payment date for such distribution. If the Company’s shares are trading at a discount to net asset value, the Company typically purchases shares in the open market in connection with the Company’s obligations under the DRIP.

For income tax purposes, the Company has reported its distributions for the 2023 calendar year as ordinary income. The character of such distributions was appropriately reported to the Internal Revenue Service and stockholders for the 2023 calendar year. To the extent the Company’s taxable earnings for a fiscal and taxable year fall below the amount of distributions paid for the fiscal and taxable year, a portion of the total amount of the Company’s distributions for the fiscal and taxable year is deemed a return of capital for U.S. federal income tax purposes to the Company’s stockholders.

The following table reflects the distributions per share that the Company has paid, including shares issued under the DRIP, on its common stock during the six months ended March 31, 2024 and 2023:

OSI2 Citibank Facility

On January 23, 2023, as a result of the consummation of the OSI2 Merger, the Company became party to a revolving credit facility (as amended and/or restated from time to time, the “OSI2 Citibank Facility”) with OSI 2 SPV, the Company’s

wholly-owned and consolidated subsidiary, as the borrower, the Company, as collateral manager, each of the lenders from time to time party thereto, Citibank, N.A., as administrative agent, and Deutsche Bank Trust Company Americas, as collateral agent.

As of March 31, 2024, the Company was able to borrow up to $400 million under the OSI2 Citibank Facility (subject to borrowing base and other limitations). As of March 31, 2024, the OSI2 Citibank Facility had a reinvestment period through May 25, 2025, during which advances may be made, and matures on January 26, 2027. Following the reinvestment period, OSI 2 SPV will be required to make certain mandatory amortization payments. Borrowings under the OSI2 Citibank Facility bear interest payable quarterly at a rate per year equal to (a) in the case of a lender that is identified as a conduit lender, the lesser of (i) the applicable commercial paper rate for such conduit lender and (ii) SOFR plus 2.00% per annum on broadly syndicated loans and 2.75% on all other eligible loans and (b) for all other lenders, SOFR plus 2.00% per annum on broadly syndicated loans and 2.75% per annum on all other eligible loans, in all cases subject to a minimum overall rate of SOFR plus 2.50% per annum. After the reinvestment period, the applicable spread is 4.00% per year. There is also a non-usage fee of 0.50% per year on the unused portion of the OSI2 Citibank Facility, payable quarterly; provided that if the unused portion of the OSI2 Citibank Facility is greater than 30% of the commitments under the OSI2 Citibank Facility, the non-usage fee will be based on an unused portion of 30% of the commitments under the OSI2 Citibank Facility. The OSI2 Citibank Facility is secured by a first priority security interest in substantially all of OSI 2 SPV’s assets. As part of the OSI2 Citibank Facility, OSI 2 SPV is subject to certain limitations as to how borrowed funds may be used and the types of loans that are eligible to be acquired by OSI 2 SPV including restrictions on sector concentrations, loan size, tenor and minimum investment ratings (or estimated ratings). The OSI2 Citibank Facility also contains certain requirements relating to interest coverage, collateral quality and portfolio performance, certain violations of which could result in the acceleration of the amounts due under the OSI2 Citibank Facility.

As of each of March 31, 2024 and September 30, 2023, the Company had $280.0 million outstanding under the OSI2 Citibank Facility, which had a fair value of $280.0 million. The Company’s borrowings under the OSI2 Citibank Facility bore interest at a weighted average interest rate of 8.079% and 7.172% for the six months ended March 31, 2024 and the period from January 23, 2023 to March 31, 2023, respectively. For the three and six months ended March 31, 2024, the Company recorded interest expense (inclusive of fees) of $6.0 million and $12.1 million, respectively, related to the OSI2 Citibank Facility.

The 2025 Notes are the Company's general unsecured obligations that rank senior in right of payment to all of the Company's existing and future indebtedness that is expressly subordinated in right of payment to the 2025 Notes. The 2025 Notes rank equally in right of payment with all of the Company's existing and future liabilities that are not so subordinated. The 2025 Notes effectively rank junior to any of the Company's secured indebtedness (including unsecured indebtedness that the Company later secures) to the extent of the value of the assets securing such indebtedness. The 2025 Notes rank structurally junior to all existing and future indebtedness (including trade payables) incurred by the Company's subsidiaries, financing vehicles or similar facilities.

The 2025 Notes were issued in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof. During the three and six months ended March 31, 2024, the Company did not repurchase any of the 2025 Notes in the open market.

The 2025 Notes Indenture contains certain covenants, including covenants requiring the Company's compliance with the asset coverage requirements set forth in Section 18(a)(1)(A) as modified by Section 61(a)(1) and (2) of the Investment Company Act or any successor provisions (but giving effect to any exemptive relief granted to the Company by the U.S. Securities and Exchange Commission ("SEC")), as well as covenants requiring the Company to provide financial information to the holders of the 2025 Notes and the Trustee if the Company ceases to be subject to the reporting requirements of the

Taxable/Distributable Income and Dividend Distributions

6 Months Ended

Income Tax Disclosure [Abstract]

Taxable/Distributable Income and Dividend Distributions

Taxable/Distributable Income and Dividend Distributions

Taxable income differs from net increase (decrease) in net assets resulting from operations primarily due to: (1) unrealized appreciation (depreciation) on investments and foreign currency, as gains and losses are not included in taxable income until they are realized; (2) origination and exit fees received in connection with investments in portfolio companies; (3) organizational costs; (4) income or loss recognition on exited investments; and (5) recognition of interest income on certain loans.

As of September 30, 2023, the Company had net capital loss carryforwards of $558.3 million to offset net capital gains that will not expire, to the extent available and permitted by U.S. federal income tax law, of which $70.3 million are available to offset future short-term capital gains and $488.0 million are available to offset future long-term capital gains. A portion of such net capital loss carryforwards represented a realized loss under sections 382 and 383 of the Code, which is carried forward to future years to offset future gains subject to certain limitations.

Listed below is a reconciliation of "net increase (decrease) in net assets resulting from operations" to taxable income for the three and six months ended March 31, 2024 and 2023.

	Three months ended March 31, 2024		Three months ended March 31, 2023		Six months ended March 31, 2024		Six months ended March 31, 2023

 __________

(1) The Company's taxable income for the three and six months ended March 31, 2024 is an estimate and will not be finally determined until the Company files its tax return for the fiscal year ending September 30, 2024. Therefore, the final taxable income may be different than the estimate.

The Company uses the liability method to account for its taxable subsidiaries' income taxes. Using this method, the Company recognizes deferred tax assets and liabilities for the estimated future tax effects attributable to temporary differences between financial reporting and tax bases of assets and liabilities. In addition, the Company recognizes deferred tax benefits associated with net loss carry forwards that it may use to offset future tax obligations. The Company measures deferred tax assets and liabilities using the enacted tax rates expected to apply to taxable income in the years in which it expects to recover or settle those temporary differences.

When assessing the realizability of deferred tax assets, the Company considers whether it is probable that some or all of the deferred tax assets will not be realized. In determining whether the deferred tax assets are realizable, the Company considers the period of expiration of the tax asset, historical and projected taxable income and tax liabilities for the tax jurisdiction in which the tax asset is located. The deferred tax asset recognized by the Company, as it relates to the higher tax basis in the carrying value of certain assets compared to the book basis of those assets, will be recognized in future years by these taxable entities. Deferred tax assets are based on the amount of the tax benefit that the Company’s management has determined is more likely than not to be realized in future periods. In determining the realizability of this tax benefit, management considered numerous factors that will give rise to pre-tax income in future periods. Among these are the historical and expected future

book and tax basis pre-tax income of the Company and unrealized gains in the Company’s assets at the determination date. Based on these and other factors, the Company determined that, as of March 31, 2024, $8.6 million of the $8.6 million deferred tax assets would not more likely than not be realized in future periods.

For the three months ended March 31, 2024, the Company recognized a total expense for income tax related to realized and unrealized gains (losses) of $0.2 million, which was composed primarily of a current income tax expense. For the three months ended March 31, 2023, the Company recognized a total expense for income tax related to realized and unrealized losses of $0.1 million, which was primarily current income tax expense.

For the six months ended March 31, 2024, the Company recognized a total expense for income tax related to realized and unrealized gains (losses) of $0.4 million, which was composed primarily of a current income tax expense. For the six months ended March 31, 2023, the Company recognized a total benefit for income tax related to realized and unrealized losses of $0.5 million, which was composed of (i) a current income tax benefit of approximately $0.4 million, and (ii) a deferred income tax benefit of approximately $0.1 million, which resulted from unrealized depreciation on investments held by the Company’s wholly-owned taxable subsidiaries.

As of September 30, 2023, the Company's last tax year end, the components of accumulated overdistributed earnings on a tax basis were as follows:

Undistributed ordinary income, net	$	33,525
Net realized capital losses	(509,832)
Unrealized losses, net	(175,031)
Accumulated overdistributed earnings	$	(651,338)

The aggregate cost of investments for U.S. federal income tax purposes was $3,070.0 million as of September 30, 2023. As of September 30, 2023, the aggregate gross unrealized appreciation for all investments in which there was an excess of value over cost for U.S. federal income tax purposes was $529.5 million. As of September 30, 2023, the aggregate gross unrealized depreciation for all investments in which there was an excess of cost for U.S. federal income tax purposes over value was $704.5 million. Net unrealized depreciation based on the aggregate cost of investments for U.S. federal income tax purposes was $175.0 million.

Net Unrealized Appreciation or Depreciation

Net unrealized appreciation or depreciation reflects the net change in the valuation of the portfolio pursuant to the Company's valuation guidelines and the reclassification of any prior period unrealized appreciation or depreciation.

During the three months ended March 31, 2024 and 2023, the Company recorded net unrealized depreciation of $25.3 million and $18.3 million, respectively.

As of March 31, 2024 and September 30, 2023, the Company had a liability on its Consolidated Statements of Assets and Liabilities in the amount of $18.6 million and $19.5 million, respectively, reflecting the unpaid portion of the base management fees and incentive fees payable to Oaktree.

Investment Advisory Agreement

The Company is party to the Investment Advisory Agreement. Under the Investment Advisory Agreement, the Company pays Oaktree a fee for its services under the Investment Advisory Agreement consisting of two components: a base management fee and an incentive fee. The cost of both the base management fee payable to Oaktree and any incentive fees earned by Oaktree is ultimately borne by common stockholders of the Company.

The investment advisory agreement with Oaktree was amended and restated on March 19, 2021 in connection with the closing of the OCSI Merger and on January 23, 2023 in connection with the closing of OSI2 Merger. The term “Investment Advisory Agreement” refers collectively to the agreements with Oaktree.

Unless earlier terminated as described below, the Investment Advisory Agreement will remain in effect from year-to-year if approved annually by the Board of Directors of the Company or by the affirmative vote of the holders of a majority of the Company’s outstanding voting securities, including, in either case, approval by a majority of the directors of the Company who are not interested persons. The Investment Advisory Agreement will automatically terminate in the event of its assignment. The Investment Advisory Agreement may be terminated by either party without penalty upon 60 days’ written notice to the other. The Investment Advisory Agreement may also be terminated, without penalty, upon the vote of a majority of the outstanding voting securities of the Company.

Base Management Fee

Under the Investment Advisory Agreement, the base management fee is calculated at an annual rate of 1.50% of total gross assets, including any investment made with borrowings, but excluding cash and cash equivalents. The base management fee is payable quarterly in arrears and the fee for any partial month or quarter is appropriately prorated. Effective May 3, 2019, the base management fee on the Company’s gross assets, including any investments made with borrowings, but excluding any cash and cash equivalents, that exceed the product of (A) 200% and (B) the Company’s net asset value will be 1.00%. For the avoidance of doubt, the 200% will be calculated in accordance with the Investment Company Act and will give effect to exemptive relief the Company received from the SEC with respect to debentures issued by a small business investment company subsidiary. In connection with the OCSI Merger, Oaktree waived an aggregate of $6 million of base management fees otherwise payable to Oaktree in the two years following the closing of the OCSI Merger on March 19, 2021 at a rate of $750,000 per quarter (with such amount appropriately prorated for any partial quarter). In connection with the OSI2 Merger, Oaktree waived an aggregate of $9.0 million of base management fees payable to Oaktree as follows: $6.0 million at a rate of $1.5 million per quarter (with such amount appropriately prorated for any partial quarter) in the first year following closing of the OSI2 Merger on January 23, 2023 and $3.0 million at a rate of $750,000 per quarter (with such amount appropriately prorated for any partial quarter) in the second year following closing of the OSI2 Merger.

On April 26, 2024, Oaktree waived additional base management fees such that the total amount of waived base management fees (including those waived in connection with the OSI2 Merger described above) will be $1.5 million for each of the three months ended March 31, 2024 and June 30, 2024. In addition, effective July 1, 2024, the base management fee will be calculated (net of base management fees previously waived by Oaktree) at an annual rate of 1.00% of total gross assets, including any investments made with borrowings, but excluding cash and cash equivalents.

For the three and six months ended March 31, 2024, the base management fee incurred under the Investment Advisory Agreement was $10.1 million (net of waiver) and $20.1 million (net of waiver), respectively. For the three and six months ended March 31, 2023, the base management fee incurred under the Investment Advisory Agreement was $9.7 million (net of waiver) and $18.9 million (net of waiver), respectively.

Incentive Fee

The incentive fee consists of two parts. Under the Investment Advisory Agreement, the first part of the incentive fee (the “incentive fee on income” or "Part I incentive fee") is calculated and payable quarterly in arrears based upon the “pre-incentive fee net investment income” of the Company for the immediately preceding quarter. The payment of the incentive fee on income is subject to payment of a preferred return to investors each quarter (i.e., a “hurdle rate”), expressed as a rate of return on the value of the Company’s net assets at the end of the most recently completed quarter, of 1.50%, subject to a “catch up” feature.

For this purpose, “pre-incentive fee net investment income” means interest income, dividend income and any other income (including any other fees such as commitment, origination, structuring, diligence and consulting fees or other fees that the Company receives from portfolio companies, other than fees for providing managerial assistance) accrued during the fiscal quarter, minus the Company’s operating expenses for the quarter (including the base management fee, expenses payable under the Administration Agreement and any interest expense and dividends paid on any issued and outstanding preferred stock, but excluding the incentive fee). Pre-incentive fee net investment income includes, in the case of investments with a deferred interest feature (such as OID debt, instruments with PIK interest and zero coupon securities), accrued income that the Company has not yet received in cash. Pre-incentive fee net investment income does not include any realized capital gains, realized capital losses or unrealized capital appreciation or depreciation. In addition, pre-incentive fee net investment income does not include any amortization or accretion of any purchase premium or purchase discount to interest income resulting solely from merger-related accounting adjustments in connection with the assets acquired in the OCSI Merger or in the OSI2 Merger, in each case, including any premium or discount paid for the acquisition of such assets, solely to the extent that the inclusion of such merger-related accounting adjustments, in the aggregate, would result in an increase in pre-incentive fee net investment income.

Under the Investment Advisory Agreement, the calculation of the incentive fee on income for each quarter is as follows:

•No incentive fee is payable to Oaktree in any quarter in which the Company’s pre-incentive fee net investment income does not exceed the preferred return rate of 1.50% (the “preferred return”) on net assets;

•100% of the Company’s pre-incentive fee net investment income, if any, that exceeds the preferred return but is less than or equal to 1.8182% in any fiscal quarter is payable to Oaktree. This portion of the incentive fee on income is referred to as the “catch-up” provision, and it is intended to provide Oaktree with an incentive fee of 17.5% on all of the Company’s pre-incentive fee net investment income when the Company’s pre-incentive fee net investment income exceeds 1.8182% on net assets in any fiscal quarter; and

•For any quarter in which the Company’s pre-incentive fee net investment income exceeds 1.8182% on net assets, the incentive fee on income is equal to 17.5% of the amount of the Company’s pre-incentive fee net investment income, as the preferred return and catch-up will have been achieved.

There is no accumulation of amounts on the hurdle rate from quarter to quarter and accordingly there is no clawback of amounts previously paid if subsequent quarters are below the quarterly hurdle.

For the three and six months ended March 31, 2024, the first part of the incentive fee (incentive fee on income) incurred under the Investment Advisory Agreement was $8.5 million and $17.5 million, respectively. For the three and six months ended March 31, 2023, the first part of the incentive fee (incentive fee on income) incurred under the Investment Advisory Agreement was $9.0 million and $16.7 million, respectively.

Under the Investment Advisory Agreement, the second part of the incentive fee (the "capital gains incentive fee") is determined and payable in arrears as of the end of each fiscal year (or upon termination of the Investment Advisory Agreement, as of the termination date) commencing with the fiscal year ended September 30, 2019 and equals 17.5% of the Company’s realized capital gains, if any, on a cumulative basis from the beginning of the fiscal year ended September 30, 2019 through the end of each subsequent fiscal year, computed net of all realized capital losses and unrealized capital depreciation on a cumulative basis, less the aggregate amount of any previously paid capital gain incentive fees under the Investment Advisory Agreement. Any realized capital gains, realized capital losses, unrealized capital appreciation and unrealized capital depreciation with respect to the Company’s portfolio as of the end of the fiscal year ended September 30, 2018 are excluded from the calculations of the second part of the incentive fee. In addition, the calculation of realized capital gains, realized capital losses and unrealized capital depreciation does (1) not include any such amounts resulting solely from merger-related accounting adjustments in connection with the assets acquired in the OCSI Merger or in the OSI2 Merger, in each case, including any premium or discount paid for the acquisition of such assets, solely to the extent that the inclusion of such merger-related accounting adjustments, in the aggregate, would result in an increase in the capital gains incentive fee, (2) include any such amounts associated with the investments acquired in the OCSI Merger for the period from October 1, 2018 to the date of closing of the OCSI Merger, solely to the extent that the exclusion of such amounts, in the aggregate, would result in an increase in the capital gains incentive fee and (3) include any such amounts associated with the investments acquired in the OSI2 Merger for the period from August 6, 2018 to the date of closing of the OSI2 Merger, solely to the extent that the exclusion of such amounts, in the aggregate, would result in an increase in the capital gains incentive fee. As of March 31, 2024, the Company paid $9.6 million of capital gains incentive fees cumulatively under the Investment Advisory Agreement (net of waivers). Part II incentive fees are contractually calculated and paid at the end of the fiscal year in accordance with the Investment Advisory Agreement, which, as described above, differs from Part II incentive fees accrued under GAAP. Hypothetically, if Part II incentive fees were calculated as of March 31, 2024 under the Investment Advisory Agreement, no Part II incentive fees would be payable.

GAAP requires that the capital gains incentive fee accrual consider the cumulative aggregate unrealized capital appreciation in the calculation, as a capital gains incentive fee would be payable if such unrealized capital appreciation were realized on a theoretical "liquidation basis." A fee so calculated and accrued would not be payable under applicable law and may never be paid based upon the computation of capital gains incentive fees in subsequent periods. Amounts ultimately paid under the Investment Advisory Agreement will be consistent with the formula reflected in the Investment Advisory Agreement. This GAAP accrual is calculated using the aggregate cumulative realized capital gains and losses and aggregate cumulative unrealized capital depreciation included in the calculation of the capital gains incentive fee plus the aggregate cumulative unrealized capital appreciation. Any realized capital gains and losses and cumulative unrealized capital appreciation and depreciation with respect to the Company’s portfolio as of the end of the fiscal year ended September 30, 2018 are excluded from the GAAP accrual. If such amount is positive at the end of a period, then GAAP requires the Company to record a capital gains incentive fee equal to 17.5% of such cumulative amount, less the aggregate amount of actual capital gains incentive fees payable or capital gains incentive fees accrued under GAAP in all prior periods. The resulting accrual for any capital gains incentive fee under GAAP in a given period may result in an additional expense if such cumulative amount is greater than in the prior period or a reversal of previously recorded expense if such cumulative amount is less than in the prior period. If such cumulative amount is negative, then there is no accrual. There can be no assurance that such unrealized capital appreciation will

be realized in the future or any accrued capital gains incentive fee will become payable under the Investment Advisory Agreement. For the three and six months ended March 31, 2024 and 2023, there were no accrued capital gains incentive fees. As of March 31, 2024, the total accrued capital gains incentive fee liability was zero.

Indemnification

The Investment Advisory Agreement provides that, absent willful misfeasance, bad faith or gross negligence in the performance of their respective duties or by reason of the reckless disregard of their respective duties and obligations, Oaktree and its officers, managers, partners, members (and their members, including the owners of their members), agents, employees, controlling persons and any other person or entity affiliated with it, are entitled to indemnification from the Company for any damages, liabilities, costs and expenses (including reasonable attorneys' fees and amounts reasonably paid in settlement) arising from the rendering of Oaktree's services under the Investment Advisory Agreement or otherwise as investment adviser.

Administrative Services

The Company is party to the Administration Agreement with Oaktree Administrator. Pursuant to the Administration Agreement, Oaktree Administrator provides administrative services to the Company necessary for the operations of the Company, which include providing office facilities, equipment, clerical, bookkeeping and record keeping services at such facilities and such other services as Oaktree Administrator, subject to review by the Company’s Board of Directors, shall from time to time deem to be necessary or useful to perform its obligations under the Administration Agreement. Oaktree Administrator may, on behalf of the Company, conduct relations and negotiate agreements with custodians, trustees, depositories, attorneys, underwriters, brokers and dealers, corporate fiduciaries, insurers, banks and such other persons in any such other capacity deemed to be necessary or desirable. Oaktree Administrator makes reports to the Company’s Board of Directors of its performance of obligations under the Administration Agreement and furnishes advice and recommendations with respect to such other aspects of the Company’s business and affairs, in each case, as it shall determine to be desirable or as reasonably required by the Company’s Board of Directors; provided that Oaktree Administrator shall not provide any investment advice or recommendation.

Oaktree Administrator also provides portfolio collection functions for interest income, fees and warrants and is responsible for the financial and other records that the Company is required to maintain and prepares, prints and disseminates reports to the Company’s stockholders and all other materials filed with the SEC. In addition, Oaktree Administrator assists the Company in determining and publishing the Company’s net asset value, overseeing the preparation and filing of the Company’s tax returns, and generally overseeing the payment of the Company’s expenses and the performance of administrative and professional services rendered to the Company by others. Oaktree Administrator may also offer to provide, on the Company’s behalf, managerial assistance to the Company’s portfolio companies.

For providing these services, facilities and personnel, the Company reimburses Oaktree Administrator the allocable portion of overhead and other expenses incurred by Oaktree Administrator in performing its obligations under the Administration Agreement, including the Company’s allocable portion of the rent of the Company’s principal executive offices (which are located in a building owned by a Brookfield affiliate) at market rates and the Company’s allocable portion of the costs of compensation and related expenses of its Chief Financial Officer, Chief Compliance Officer, their staffs and other non-investment professionals at Oaktree that perform duties for the Company. Such reimbursement is at cost, with no profit to, or markup by, Oaktree Administrator. The Administration Agreement may be terminated by either party without penalty upon 60 days’ written notice to the other. The Administration Agreement may also be terminated, without penalty, upon the vote of a majority of the Company’s outstanding voting securities.

For each of the three months ended March 31, 2024 and 2023, the Company accrued administrative expenses of $0.4 million, including $0.1 million of general and administrative expenses. For the six months ended March 31, 2024 and 2023, the Company accrued administrative expenses of $0.9 million and $0.8 million, respectively, including $0.2 million and $0.2 million of general and administrative expenses, respectively.

As of March 31, 2024 and September 30, 2023, $3.8 million and $4.3 million, respectively, was included in “Due to affiliate” in the Consolidated Statements of Assets and Liabilities, reflecting the unpaid portion of administrative expenses and other reimbursable expenses payable to Oaktree Administrator.

General Description of Registrant [Abstract]

Investment Objectives and Practices [Text Block]

Our investment objective is to generate current income and capital appreciation by providing companies with flexible and innovative financing solutions, including first and second lien loans, unsecured and mezzanine loans, bonds, preferred equity and certain equity co-investments. We may also seek to generate capital appreciation and income through secondary investments at discounts to par in either private or syndicated transactions. Our portfolio may also include certain structured finance and other non-traditional structures. We invest in companies that typically possess resilient business models with strong underlying fundamentals. We intend to deploy capital across credit and economic cycles with a focus on long-term results, which we believe will enable us to build lasting partnerships with financial sponsors and management teams, and we may seek to opportunistically take advantage of dislocations in the financial markets and other situations that may benefit from Oaktree’s credit and structuring expertise. Sponsors may include financial sponsors, such as an institutional investor or a private equity firm, or a strategic entity seeking to invest in a portfolio company. We generally invest in securities that are rated below investment grade by rating agencies or that would be rated below investment grade if they were rated. Below investment grade securities, which are often referred to as “high yield” and “junk,” have predominantly speculative characteristics with respect to the issuer’s capacity to pay interest and repay principal.

In the current market environment, Oaktree intends to focus on the following areas, in which Oaktree believes there is less competition and thus potential for greater returns, for our new investment opportunities: (1) situational lending, which we define to include directly originated loans to non-sponsor companies that are hard to understand and value using traditional underwriting techniques, (2) select sponsor lending, which we define to include financing to support leveraged buyouts of companies with specialized sponsors that have expertise in certain industries, (3) stressed sector and rescue lending, which we define to include opportunistic private loans in industries experiencing stress or limited access to capital and (4) public credit, where we seek discounted, high quality public debt investments particularly in times of market dislocation.

Capital Stock, Long-Term Debt, and Other Securities [Abstract]

Long Term Debt [Table Text Block]

Syndicated Facility

On November 30, 2017, the Company entered into a senior secured revolving credit facility (as amended and restated, the “Syndicated Facility”) pursuant to a Senior Secured Revolving Credit Agreement with the lenders party thereto, ING Capital LLC, as administrative agent, ING Capital LLC, JPMorgan Chase Bank, N.A., BofA Securities, Inc. and MUFG Union Bank, N.A., as joint lead arrangers and joint bookrunners, and JPMorgan Chase Bank, N.A. and Bank of America, N.A., as syndication agents. The Syndicated Facility provides that the Company may use the proceeds of the loans and issuances of letters of credit under the Syndicated Facility for general corporate purposes, including acquiring and funding leveraged loans,

mezzanine loans, high-yield securities, convertible securities, preferred stock, common stock and other investments. The Syndicated Facility further allows the Company to request letters of credit from ING Capital LLC, as the issuing bank.

As of March 31, 2024, the size of the Syndicated Facility was $1.218 billion. In addition, pursuant to an "accordion" feature, the Company may increase the size of the facility to up to the greater of $1.25 billion and the Company's net worth, as defined in the facility, under certain circumstances.

As of March 31, 2024, (i) the period during which the Company may make drawings with respect to $1.035 billion of commitments will expire on June 23, 2027 and the maturity date is June 23, 2028, (ii) the period during which the Company may make drawings with respect to the remaining commitments will expire on May 4, 2025 and the maturity date is May 4, 2026 and (iii) the interest rate margin for (a) SOFR loans (which may be 1- or 3-month, at the Company’s option) was 2.00% plus a SOFR adjustment which ranges between 0.11448% and 0.26161% and (b) alternate base rate loans was 1.00%.

The Syndicated Facility is secured by substantially all of the Company’s assets (excluding, among other things, investments held in and by certain subsidiaries of the Company (including OSI 2 Senior Lending SPV, LLC, or “OSI 2 SPV”) or investments in certain portfolio companies of the Company) and guaranteed by certain subsidiaries of the Company.

The Syndicated Facility requires the Company to, among other things, (i) make representations and warranties regarding the collateral as well as each of the Company’s portfolio companies’ businesses, (ii) agree to certain indemnification obligations, and (iii) comply with various affirmative and negative covenants, reporting requirements and other customary requirements for similar revolving credit facilities, including covenants related to: (A) limitations on the incurrence of additional indebtedness and liens, (B) limitations on certain investments, (C) limitations on certain asset transfers and restricted payments, (D) maintaining a certain minimum stockholders’ equity, (E) maintaining a ratio of total assets (less total liabilities) to total indebtedness, of the Company and its subsidiaries (subject to certain exceptions), of not less than 1.50 to 1.00, (F) maintaining a ratio of consolidated EBITDA to consolidated interest expense, of the Company and its subsidiaries (subject to certain exceptions), of not less than 2.25 to 1.00, (G) maintaining a minimum liquidity and net worth, and (H) limitations on the creation or existence of agreements that prohibit liens on certain properties of the Company and certain of its subsidiaries. The Syndicated Facility also includes usual and customary default provisions such as the failure to make timely payments under the facility, the occurrence of a change in control, and the failure by the Company to materially perform under the agreements governing the facility, which, if not complied with, could accelerate repayment under the facility. As of March 31, 2024, the Company was in compliance with all financial covenants under the Syndicated Facility. In addition to the asset coverage ratio described above, borrowings under the Syndicated Facility (and the incurrence of certain other permitted debt) are subject to compliance with a borrowing base that will apply different advance rates to different types of assets in the Company’s portfolio. Each loan or letter of credit originated or assumed under the Syndicated Facility is subject to the satisfaction of certain conditions.

As of March 31, 2024 and September 30, 2023, the Company had $450.0 million and $430.0 million of borrowings outstanding under the Syndicated Facility, which had a fair value of $450.0 million and $430.0 million, respectively. The Company's borrowings under the Syndicated Facility bore interest at a weighted average interest rate of 7.579% and 6.255% for the six months ended March 31, 2024 and 2023, respectively. For the three and six months ended March 31, 2024, the Company recorded interest expense (inclusive of fees) of $9.6 million and $19.1 million, respectively, related to the Syndicated Facility. For the three and six months ended March 31, 2023, the Company recorded interest expense (inclusive of fees) of $13.1 million and $23.1 million, respectively, related to the Syndicated Facility.

Citibank Facility

On March 19, 2021, the Company became party to a revolving credit facility (as amended and/or restated from time to time, the “Citibank Facility”) with OCSL Senior Funding II LLC, the Company’s wholly-owned, special purpose financing subsidiary, as the borrower, the Company, as collateral manager and seller, each of the lenders from time to time party thereto, Citibank, N.A., as administrative agent, and Wells Fargo Bank, National Association, as collateral agent and custodian. On May 25, 2023, in connection with an amendment to the OSI2 Citibank Facility, the Citibank Facility was terminated.

As of March 31, 2024 and September 30, 2023, the Company did not have any borrowings outstanding under the Citibank Facility. The Company's borrowings under the Citibank Facility bore interest at a weighted average interest rate of 6.678% for the six months ended March 31, 2023. For the three and six months ended March 31, 2023, the Company recorded interest expense (inclusive of fees) of $2.9 million and $5.6 million, respectively, related to the Citibank Facility.

On January 23, 2023, as a result of the consummation of the OSI2 Merger, the Company became party to a revolving credit facility (as amended and/or restated from time to time, the “OSI2 Citibank Facility”) with OSI 2 SPV, the Company’s

wholly-owned and consolidated subsidiary, as the borrower, the Company, as collateral manager, each of the lenders from time to time party thereto, Citibank, N.A., as administrative agent, and Deutsche Bank Trust Company Americas, as collateral agent.

As of March 31, 2024, the Company was able to borrow up to $400 million under the OSI2 Citibank Facility (subject to borrowing base and other limitations). As of March 31, 2024, the OSI2 Citibank Facility had a reinvestment period through May 25, 2025, during which advances may be made, and matures on January 26, 2027. Following the reinvestment period, OSI 2 SPV will be required to make certain mandatory amortization payments. Borrowings under the OSI2 Citibank Facility bear interest payable quarterly at a rate per year equal to (a) in the case of a lender that is identified as a conduit lender, the lesser of (i) the applicable commercial paper rate for such conduit lender and (ii) SOFR plus 2.00% per annum on broadly syndicated loans and 2.75% on all other eligible loans and (b) for all other lenders, SOFR plus 2.00% per annum on broadly syndicated loans and 2.75% per annum on all other eligible loans, in all cases subject to a minimum overall rate of SOFR plus 2.50% per annum. After the reinvestment period, the applicable spread is 4.00% per year. There is also a non-usage fee of 0.50% per year on the unused portion of the OSI2 Citibank Facility, payable quarterly; provided that if the unused portion of the OSI2 Citibank Facility is greater than 30% of the commitments under the OSI2 Citibank Facility, the non-usage fee will be based on an unused portion of 30% of the commitments under the OSI2 Citibank Facility. The OSI2 Citibank Facility is secured by a first priority security interest in substantially all of OSI 2 SPV’s assets. As part of the OSI2 Citibank Facility, OSI 2 SPV is subject to certain limitations as to how borrowed funds may be used and the types of loans that are eligible to be acquired by OSI 2 SPV including restrictions on sector concentrations, loan size, tenor and minimum investment ratings (or estimated ratings). The OSI2 Citibank Facility also contains certain requirements relating to interest coverage, collateral quality and portfolio performance, certain violations of which could result in the acceleration of the amounts due under the OSI2 Citibank Facility.

As of each of March 31, 2024 and September 30, 2023, the Company had $280.0 million outstanding under the OSI2 Citibank Facility, which had a fair value of $280.0 million. The Company’s borrowings under the OSI2 Citibank Facility bore interest at a weighted average interest rate of 8.079% and 7.172% for the six months ended March 31, 2024 and the period from January 23, 2023 to March 31, 2023, respectively. For the three and six months ended March 31, 2024, the Company recorded interest expense (inclusive of fees) of $6.0 million and $12.1 million, respectively, related to the OSI2 Citibank Facility. For the period from January 23, 2023 to March 31, 2023, the Company recorded interest expense (inclusive of fees) of $3.1 million related to the OSI2 Citibank Facility.

2025 Notes

On February 25, 2020, the Company issued $300.0 million in aggregate principal amount of the 2025 Notes for net proceeds of $293.8 million after deducting OID of $2.5 million, underwriting commissions and discounts of $3.0 million and offering costs of $0.7 million. The OID on the 2025 Notes is amortized based on the effective interest method over the term of the 2025 Notes.

The 2025 Notes were issued pursuant to an indenture, dated April 30, 2012, as supplemented by the fifth supplemental indenture, dated February 25, 2020 (collectively, the "2025 Notes Indenture"), between the Company and Deutsche Bank Trust Company Americas (the "Trustee"). The 2025 Notes are the Company's general unsecured obligations that rank senior in right of payment to all of the Company's existing and future indebtedness that is expressly subordinated in right of payment to the 2025 Notes. The 2025 Notes rank equally in right of payment with all of the Company's existing and future liabilities that are not so subordinated. The 2025 Notes effectively rank junior to any of the Company's secured indebtedness (including unsecured indebtedness that the Company later secures) to the extent of the value of the assets securing such indebtedness. The 2025 Notes rank structurally junior to all existing and future indebtedness (including trade payables) incurred by the Company's subsidiaries, financing vehicles or similar facilities.

Interest on the 2025 Notes is paid semi-annually on February 25 and August 25 at a rate of 3.500% per annum. The 2025 Notes mature on February 25, 2025 and may be redeemed in whole or in part at any time or from time to time at the Company's option prior to maturity at par plus a “make-whole” premium, if applicable. In addition, holders of the 2025 Notes can require the Company to repurchase the 2025 Notes at 100% of their principal amount upon the occurrence of certain change of control events as described in the 2025 Notes Indenture. The 2025 Notes were issued in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof. During the three and six months ended March 31, 2024, the Company did not repurchase any of the 2025 Notes in the open market.

The 2025 Notes Indenture contains certain covenants, including covenants requiring the Company's compliance with the asset coverage requirements set forth in Section 18(a)(1)(A) as modified by Section 61(a)(1) and (2) of the Investment Company Act or any successor provisions (but giving effect to any exemptive relief granted to the Company by the U.S. Securities and Exchange Commission ("SEC")), as well as covenants requiring the Company to provide financial information to the holders of the 2025 Notes and the Trustee if the Company ceases to be subject to the reporting requirements of the

These covenants are subject to limitations and exceptions that are described in the 2027 Notes Indenture.

In connection with the 2027 Notes, the Company entered into an interest rate swap to more closely align the interest rates of its liabilities with its investment portfolio, which consists of predominately floating rate loans. Under the interest rate swap agreement, the Company receives a fixed interest rate of 2.700% and pays a floating interest rate of the three-month SOFR plus 1.658% plus a SOFR adjustment of 0.26161% on a notional amount of $350.0 million.

Long Term Debt, Dividends and Covenants [Text Block]

As of March 31, 2024, the OSI2 Citibank Facility had a reinvestment period through May 25, 2025, during which advances may be made, and matures on January 26, 2027. Following the reinvestment period, OSI 2 SPV will be required to make certain mandatory amortization payments. Borrowings under the OSI2 Citibank Facility bear interest payable quarterly at a rate per year equal to (a) in the case of a lender that is identified as a conduit lender, the lesser of (i) the applicable commercial paper rate for such conduit lender and (ii) SOFR plus 2.00% per annum on broadly syndicated loans and 2.75% on all other eligible loans and (b) for all other lenders, SOFR plus 2.00% per annum on broadly syndicated loans and 2.75% per annum on all other eligible loans, in all cases subject to a minimum overall rate of SOFR plus 2.50% per annum. After the reinvestment period, the applicable spread is 4.00% per year. There is also a non-usage fee of 0.50% per year on the unused portion of the OSI2 Citibank Facility, payable quarterly; provided that if the unused portion of the OSI2 Citibank Facility is greater than 30% of the commitments under the OSI2 Citibank Facility, the non-usage fee will be based on an unused portion of 30% of the commitments under the OSI2 Citibank Facility. The OSI2 Citibank Facility is secured by a first priority security interest in substantially all of OSI 2 SPV’s assets. As part of the OSI2 Citibank Facility, OSI 2 SPV is subject to certain limitations as to how borrowed funds may be used and the types of loans that are eligible to be acquired by OSI 2 SPV including restrictions on sector concentrations, loan size, tenor and minimum investment ratings (or estimated ratings).

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation:

The Consolidated Financial Statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") and pursuant to the requirements for reporting on Form 10-Q and Regulation S-X. In the opinion of management, all adjustments of a normal recurring nature considered necessary for the fair presentation of the Consolidated Financial Statements have been made. All intercompany balances and transactions have been eliminated. The Company is an investment company following the accounting and reporting guidance in ASC Topic 946, Financial Services - Investment Companies ("ASC 946").

Certain prior period amounts have been reclassified to conform to the current period presentation. All per share amounts and common shares outstanding have been retroactively adjusted as necessary to reflect the Company's 1-for-3 reverse stock split completed on January 20, 2023 and effective as of the commencement of trading on January 23, 2023.

Use of Estimates

Use of Estimates:

The preparation of the financial statements in conformity with GAAP requires management to make certain estimates and assumptions affecting amounts reported in the financial statements and accompanying notes. These estimates are based on the information that is currently available to the Company and on various other assumptions that the Company believes to be reasonable under the circumstances. Changes in the economic and political environments, financial markets and any other parameters used in determining these estimates could cause actual results to differ and such differences could be material. Significant estimates include the valuation of investments and revenue recognition.

Consolidation

Consolidation:

The accompanying Consolidated Financial Statements include the accounts of Oaktree Specialty Lending Corporation and its consolidated subsidiaries. Each consolidated subsidiary is wholly-owned and, as such, consolidated into the Consolidated Financial Statements. Certain subsidiaries that hold investments are treated as pass through entities for U.S. federal income tax purposes. The assets of certain of the consolidated subsidiaries are not directly available to satisfy the claims of the creditors of Oaktree Specialty Lending Corporation or any of its other subsidiaries.

As an investment company, portfolio investments held by the Company are not consolidated into the Consolidated Financial Statements but rather are included on the Statements of Assets and Liabilities as investments at fair value.

Fair Value Measurements

Fair Value Measurements:

Oaktree, as the valuation designee of the Company's Board of Directors pursuant to Rule 2a-5 under the Investment Company Act, determines the fair value of our assets on at least a quarterly basis in accordance with ASC 820. ASC 820 defines fair value as the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. A liability's fair value is defined as the amount that would be paid to transfer the liability to a new obligor, not the amount that would be paid to settle the liability with the creditor. ASC 820 prioritizes the use of observable market prices over entity-specific inputs. Where observable prices or inputs are not available or reliable, valuation techniques are applied. These valuation techniques involve some level of management estimation and judgment, the degree of which is dependent on the price transparency for the investments or market and the investments' complexity.

Hierarchical levels, defined by ASC 820 and directly related to the amount of subjectivity associated with the inputs to fair valuation of these assets and liabilities, are as follows:

•Level 1 — Unadjusted, quoted prices in active markets for identical assets or liabilities as of the measurement date.

•Level 2 — Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data at the measurement date for substantially the full term of the assets or liabilities.

•Level 3 — Unobservable inputs that reflect Oaktree's best estimate of what market participants would use in pricing the asset or liability at the measurement date. Consideration is given to the risk inherent in the valuation technique and the risk inherent in the inputs to the model.

If inputs used to measure fair value fall into different levels of the fair value hierarchy, an investment's level is based on the lowest level of input that is significant to the fair value measurement. Oaktree's assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the investment.

This includes investment securities that are valued using "bid" and "ask" prices obtained from independent third party pricing services or directly from brokers. These investments may be classified as Level 3 because the quoted prices may be indicative in nature for securities that are in an inactive market, may be for similar securities or may require adjustments for investment-specific factors or restrictions.

Financial instruments with readily available quoted prices generally will have a higher degree of market price observability and a lesser degree of judgment inherent in measuring fair value. As such, Oaktree obtains and analyzes readily available market quotations provided by pricing vendors and brokers for all of the Company's investments for which quotations are available. In determining the fair value of a particular investment, pricing vendors and brokers use observable market information, including both binding and non-binding indicative quotations.

Oaktree seeks to obtain at least two quotations for the subject or similar securities, typically from pricing vendors. If Oaktree is unable to obtain two quotes from pricing vendors, or if the prices obtained from pricing vendors are not within Oaktree's set threshold, Oaktree seeks to obtain a quote directly from a broker making a market for the asset. Oaktree evaluates the quotations provided by pricing vendors and brokers based on available market information, including trading activity of the subject or similar securities, or by performing a comparable security analysis to ensure that fair values are reasonably estimated. Oaktree also performs back-testing of valuation information obtained from pricing vendors and brokers against actual prices received in transactions. In addition to ongoing monitoring and back-testing, Oaktree performs due diligence procedures over pricing vendors to understand their methodology and controls to support their use in the valuation process. Generally, Oaktree does not adjust any of the prices received from these sources.

If the quotations obtained from pricing vendors or brokers are determined to not be reliable or are not readily available, Oaktree values such investments using any of three different valuation techniques. The first valuation technique is the transaction precedent technique, which utilizes recent or expected future transactions of the investment to determine fair value, to the extent applicable. The second valuation technique is an analysis of the enterprise value ("EV") of the portfolio company. EV means the entire value of the portfolio company to a market participant, including the sum of the values of debt and equity securities used to capitalize the enterprise at a point in time. The EV analysis is typically performed to determine (i) the value of equity investments, (ii) whether there is credit impairment for debt investments and (iii) the value for debt investments that the Company is deemed to control under the Investment Company Act. To estimate the EV of a portfolio company, Oaktree analyzes various factors, including the portfolio company’s historical and projected financial results, macroeconomic impacts on the company and competitive dynamics in the company’s industry. Oaktree also utilizes some or all of the following information based on the individual circumstances of the portfolio company: (i) valuations of comparable public companies, (ii) recent sales of private and public comparable companies in similar industries or having similar business or earnings characteristics, (iii) purchase prices as a multiple of their earnings or cash flow, (iv) the portfolio company’s ability to meet its forecasts and its business prospects, (v) a discounted cash flow analysis, (vi) estimated liquidation or collateral value of the portfolio company's assets and (vii) offers from third parties to buy the portfolio company. Oaktree may probability weight potential sale outcomes with respect to a portfolio company when uncertainty exists as of the valuation date. The third valuation technique is a market yield technique, which is typically performed for non-credit impaired debt investments. In the market yield technique, a current price is imputed for the investment based upon an assessment of the expected market yield for a similarly structured investment with a similar level of risk, and Oaktree considers the current contractual interest rate, the capital structure and other terms of the investment relative to risk of the company and the specific investment. A key determinant of risk, among other things, is the leverage through the investment relative to the EV of the portfolio company. As debt investments held by the Company are substantially illiquid with no active transaction market, Oaktree depends on primary market data, including newly funded transactions and industry specific market movements, as well as secondary market data with respect to high yield debt instruments and syndicated loans, as inputs in determining the appropriate market yield, as applicable.

In accordance with ASC 820-10, certain investments that qualify as investment companies in accordance with ASC 946 may be valued using net asset value as a practical expedient for fair value. Consistent with FASB guidance under ASC 820, these investments are excluded from the hierarchical levels. These investments are generally not redeemable.

Oaktree estimates the fair value of certain privately held warrants using a Black Scholes pricing model, which includes an analysis of various factors and subjective assumptions, including the current stock price (by using an EV analysis as described above), the expected period until exercise, expected volatility of the underlying stock price, expected dividends and the risk free rate. Changes in the subjective input assumptions can materially affect the fair value estimates.

Rule 2a-5 under the Investment Company Act permits boards of directors of registered investment companies and Business Development Companies to either (i) choose to determine fair value in good faith or (ii) designate a valuation designee tasked with determining fair value in good faith, subject to the board’s oversight. The Company's Board of Directors has designated Oaktree to serve as its valuation designee effective September 8, 2022.

Oaktree undertakes a multi-step valuation process each quarter in connection with determining the fair value of the Company's investments:

•The quarterly valuation process begins with each portfolio company or investment being initially valued by Oaktree's valuation team;

•Preliminary valuations are then reviewed and discussed with management of Oaktree;

•Separately, independent valuation firms prepare valuations of the Company's investments, on a selected basis, for which market quotations are not readily available or are readily available but deemed not reflective of the fair value of the investment, and submit the reports to the Company and provide such reports to Oaktree;

•Oaktree compares and contrasts its preliminary valuations to the valuations of the independent valuation firms and prepares a valuation report for the Audit Committee;

•The Audit Committee reviews the valuation report with Oaktree, and Oaktree responds and supplements the valuation report to reflect any discussions between Oaktree and the Audit Committee; and

•Oaktree, as valuation designee, determines the fair value of each investment in the Company's portfolio.

The fair value of the Company's investments as of March 31, 2024 and September 30, 2023 was determined by Oaktree, as the Company's valuation designee. The Company has and will continue to engage independent valuation firms to provide assistance regarding the determination of the fair value of a portion of its portfolio securities for which market quotations are not readily available or are readily available but deemed not reflective of the fair value of the investment each quarter.

Due to the inherent uncertainty of determining the fair value of investments that do not have a readily available market value, the fair value of the Company’s investments may fluctuate from period to period. Because of the inherent uncertainty of valuation, these estimated values may differ significantly from the values that would have been reported had a ready market for the investments existed, and it is reasonably possible that the difference could be material.

With the exception of the line items entitled "deferred financing costs," "deferred offering costs," "other assets," "deferred tax liability," "credit facilities payable" and "unsecured notes payable," which are reported at amortized cost, all assets and liabilities approximate fair value on the Consolidated Statements of Assets and Liabilities. The carrying value of the line items titled "interest, dividends and fees receivable," "due from portfolio companies," "receivables from unsettled transactions," "due from broker," "accounts payable, accrued expenses and other liabilities," "base management fee and incentive fee payable," "due to affiliate," "interest payable" and "payables from unsettled transactions" approximate fair value due to their short maturities.

Foreign Currency Translation

Foreign Currency Translation:

The accounting records of the Company are maintained in U.S. dollars. All assets and liabilities denominated in foreign currencies are translated into U.S. dollars based on the prevailing foreign exchange rate on the reporting date. The Company does not isolate that portion of the results of operations resulting from changes in foreign exchange rates on investments from the fluctuations arising from changes in market prices of securities held. The Company’s investments in foreign securities may involve certain risks, including foreign exchange restrictions, expropriation, taxation or other political, social or economic risks, all of which could affect the market and/or credit risk of the investment. In addition, changes in the relationship of foreign currencies to the U.S. dollar can significantly affect the value of these investments and therefore the earnings of the Company.

Derivative Instruments

Derivative Instruments:

Foreign Currency Forward Contracts

The Company uses foreign currency forward contracts to reduce the Company's exposure to fluctuations in the value of foreign currencies. In a foreign currency forward contract, the Company agrees to receive or deliver a fixed quantity of one currency for another at a pre-determined price at a future date. Foreign currency forward contracts are marked-to-market at the applicable forward rate. Unrealized appreciation (depreciation) on foreign currency forward contracts is recorded within derivative assets or derivative liabilities on the Consolidated Statements of Assets and Liabilities by counterparty on a net basis, not taking into account collateral posted which is recorded separately, if applicable. Purchases and settlements of foreign currency forward contracts having the same settlement date and counterparty are generally settled net and any realized gains or losses are recognized on the settlement date. The Company does not utilize hedge accounting with respect to foreign currency forward contracts and, as such, the Company recognizes its foreign currency forward contracts at fair value with changes included in the net unrealized appreciation (depreciation) on the Consolidated Statements of Operations.

Interest Rate Swaps

The Company uses interest rate swaps to hedge some of the Company's fixed rate debt. The Company designated the interest rate swaps as the hedging instruments in an effective hedge accounting relationship, and therefore the periodic payments are recognized as components of interest expense in the Consolidated Statements of Operations. Depending on the nature of the balance at period end, the fair value of each interest rate swap is either included as a derivative asset or derivative liability on the Company's Consolidated Statements of Assets and Liabilities. The change in fair value of the interest rate swaps is offset by a change in the carrying value of the fixed rate debt. Any amounts paid to the counterparty to cover collateral obligations under the terms of the interest rate swap agreements are included in due from broker on the Company's Consolidated Statements of Assets and Liabilities.

Investment Income

Investment Income:

Interest Income

Interest income, adjusted for accretion of original issue discount ("OID"), is recorded on an accrual basis to the extent that such amounts are expected to be collected. The Company stops accruing interest on investments when it is determined that interest is no longer collectible. Investments that are expected to pay regularly scheduled interest in cash are generally placed on non-accrual status when there is reasonable doubt that principal or interest cash payments will be collected. Cash interest payments received on investments may be recognized as income or a return of capital depending upon management’s judgment. A non-accrual investment is restored to accrual status if past due principal and interest are paid in cash and the portfolio company, in management’s judgment, is likely to continue timely payment of its remaining obligations. As of March 31, 2024, there were five investments on non-accrual status that in aggregate represented 4.3% and 2.4% of total debt investments at cost and fair value, respectively. As of September 30, 2023, there were four investments on non-accrual status that in aggregate represented 2.4% and 1.8% of total debt investments at cost and fair value, respectively.

In connection with its investment in a portfolio company, the Company sometimes receives nominal cost equity that is valued as part of the negotiation process with the portfolio company. When the Company receives nominal cost equity, the Company allocates its cost basis in the investment between debt securities and the nominal cost equity at the time of origination. Any resulting discount from recording the loan, or otherwise purchasing a security at a discount, is accreted into interest income over the life of the loan.

PIK Interest Income

The Company's investments in debt securities may contain PIK interest provisions. PIK interest, which generally represents contractually deferred interest added to the loan balance that is generally due at the end of the loan term, is generally recorded on the accrual basis to the extent such amounts are expected to be collected. The Company generally ceases accruing PIK interest if there is insufficient value to support the accrual or if the Company does not expect the portfolio company to be able to pay all principal and interest due. The Company's decision to cease accruing PIK interest on a loan or debt security involves subjective judgments and determinations based on available information about a particular portfolio company, including whether the portfolio company is current with respect to its payment of principal and interest on its loans and debt securities; financial statements and financial projections for the portfolio company; the Company's assessment of the portfolio company's business development success; information obtained by the Company in connection with periodic formal update interviews with the portfolio company's management and, if appropriate, the private equity sponsor; and information about the general economic and market conditions in which the portfolio company operates. The Company's determination to cease accruing PIK interest is generally made well before the Company's full write-down of a loan or debt security. In addition, if it is subsequently determined that the Company will not be able to collect any previously accrued PIK interest, the fair value of the loans or debt securities would be reduced by the amount of such previously accrued, but uncollectible, PIK interest. The accrual of PIK interest on the Company’s debt investments increases the recorded cost basis of these investments in the Consolidated Financial Statements including for purposes of computing the capital gains incentive fee payable by the Company to Oaktree. To maintain its status as a RIC, certain income from PIK interest may be required to be distributed to the Company’s stockholders, even though the Company has not yet collected the cash and may never do so.

Fee Income

Oaktree or its affiliates may provide financial advisory services to portfolio companies and, in return, the Company may receive fees for capital structuring services. These fees are generally non-recurring and are recognized by the Company upon the investment closing date. The Company may also receive additional fees in the ordinary course of business, including servicing, amendment, exit and prepayment fees, which are classified as fee income and recognized as they are earned or the services are rendered.

Dividend Income

The Company generally recognizes dividend income on the ex-dividend date for public securities and the record date for private equity investments. Distributions received from private equity investments are evaluated to determine if the distribution should be recorded as dividend income or a return of capital. Generally, the Company will not record distributions from private equity investments as dividend income unless there are sufficient earnings at the portfolio company prior to the distribution. Distributions that are classified as a return of capital are recorded as a reduction in the cost basis of the investment.

Cash and Cash Equivalents and Restricted Cash

Cash and Cash Equivalents and Restricted Cash:

Cash and cash equivalents consist of demand deposits and highly liquid investments with maturities of three months or less when acquired. The Company places its cash and cash equivalents and restricted cash with financial institutions and, at times, cash held in bank accounts exceeds the Federal Deposit Insurance Corporation ("FDIC") insurance limit. Cash and cash equivalents are included on the Company's Consolidated Schedule of Investments and cash equivalents are classified as Level 1 assets.

Due From Portfolio Companies

Due from Portfolio Companies:

Due from portfolio companies consists of amounts payable to the Company from its portfolio companies, including proceeds from the sale of portfolio companies not yet received or being held in escrow and excluding those amounts attributable to interest, dividends or fees receivable. These amounts are recognized as they become payable to the Company (e.g., principal payments on the scheduled amortization payment date).

Receivables/Payables from Unsettled Transactions

Receivables/Payables from Unsettled Transactions:

Receivables/payables from unsettled transactions consist of amounts receivable to or payable by the Company for transactions that have not settled at the reporting date.

Deferred Financing Costs

Deferred Financing Costs:

Deferred financing costs consist of fees and expenses paid in connection with the closing or amending of credit facilities and debt offerings. Deferred financing costs in connection with credit facilities are capitalized as an asset when incurred. Deferred financing costs in connection with all other debt arrangements are a direct deduction from the related debt liability when incurred. Deferred financing costs are amortized using the effective interest method over the term of the respective debt arrangement. This amortization expense is included in interest expense in the Consolidated Statements of Operations. Upon early termination or modification of a credit facility, all or a portion of unamortized fees related to such facility may be accelerated into interest expense. For extinguishments of the Company’s unsecured notes payable, any unamortized deferred financing costs are deducted from the carrying amount of the debt in determining the gain or loss from the extinguishment.

Deferred Offering Costs

Deferred Offering Costs:

Legal fees and other costs incurred in connection with the Company’s shelf registration statement are capitalized as deferred offering costs in the Consolidated Statements of Assets and Liabilities. To the extent any such costs relate to equity offerings, these costs are charged as a reduction of capital upon utilization. To the extent any such costs relate to debt offerings, these costs are treated as deferred financing costs and are amortized over the term of the respective debt arrangement. Any

deferred offering costs that remain at the expiration of the shelf registration statement or when it becomes probable that an offering will not be completed are expensed.

Income Taxes

Income Taxes:

The Company has elected to be subject to tax as a RIC under Subchapter M of the Code and operates in a manner so as to qualify for the tax treatment applicable to RICs. In order to be subject to tax as a RIC, among other things, the Company is required to meet certain source of income and asset diversification requirements and timely distribute dividends to its stockholders of an amount generally at least equal to 90% of investment company taxable income, as defined by the Code and determined without regard to any deduction for dividends paid, for each taxable year. As a RIC, the Company is not subject to U.S. federal income tax on the portion of its taxable income and gains distributed currently to stockholders as a dividend. Depending on the level of taxable income earned during a taxable year, the Company may choose to retain taxable income in excess of current year dividend distributions and would distribute such taxable income in the next taxable year. The Company would then incur a 4% excise tax on such income, as required. To the extent that the Company determines that its estimated current year annual taxable income, determined on a calendar year basis, could exceed estimated current calendar year dividend distributions, the Company accrues excise tax, if any, on estimated excess taxable income as taxable income is earned. The Company anticipates timely distribution of its taxable income within the tax rules under Subchapter M of the Code. For calendar year 2022, the Company incurred $0.1 million of excise tax. The Company did not incur any U.S. federal excise tax for calendar year 2023. The Company does not expect to incur a U.S. federal excise tax for calendar year 2024.

The Company holds certain portfolio investments through taxable subsidiaries. The purpose of the Company's taxable subsidiaries is to permit the Company to hold equity investments in portfolio companies which are "pass through" entities for U.S. federal income tax purposes in order to comply with the RIC tax requirements. The taxable subsidiaries are consolidated for financial reporting purposes, and portfolio investments held by them are included in the Company’s Consolidated Financial Statements as portfolio investments and recorded at fair value. The taxable subsidiaries are not consolidated with the Company for U.S. federal income tax purposes and may generate income tax expense, or benefit, and the related tax assets and liabilities, as a result of their ownership of certain portfolio investments. This income tax expense, if any, would be reflected in the Company's Consolidated Statements of Operations. The Company uses the liability method to account for its taxable subsidiaries' income taxes. Using this method, the Company recognizes deferred tax assets and liabilities for the estimated future tax effects attributable to temporary differences between financial reporting and tax bases of assets and liabilities. In addition, the Company recognizes deferred tax benefits associated with net operating loss carry forwards that it may use to offset future tax obligations. The Company measures deferred tax assets and liabilities using the enacted tax rates expected to apply to taxable income in the years in which it expects to recover or settle those temporary differences.

FASB ASC Topic 740, Accounting for Uncertainty in Income Taxes ("ASC 740"), provides guidance for how uncertain tax positions should be recognized, measured, presented and disclosed in the Company's Consolidated Financial Statements. ASC 740 requires the evaluation of tax positions taken or expected to be taken in the course of preparing the Company's tax returns to determine whether the tax positions are "more-likely-than-not" of being sustained by the applicable tax authority. Tax positions not deemed to meet the more-likely-than-not threshold are recorded as a tax benefit or expense in the current year. Management's determinations regarding ASC 740 may be subject to review and adjustment at a later date based upon factors including an ongoing analysis of tax laws, regulations and interpretations thereof. The Company recognizes the tax benefits of uncertain tax positions only where the position is "more-likely-than-not" to be sustained assuming examination by tax authorities. Management has analyzed the Company's tax positions and has concluded that no liability for unrecognized tax benefits should be recorded related to uncertain tax positions taken on returns filed for open tax years 2021, 2022 and 2023. The Company identifies its major tax jurisdictions as U.S. Federal and California, and the Company is not aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will change materially in the next 12 months.

Recently Adopted Accounting Pronouncements

Recently Adopted Accounting Pronouncements

In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting (Topic 280), which improves reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The amendments are effective for fiscal years beginning after December 15, 2023 and interim period within fiscal years beginning after December 15, 2024. The Company does not expect this guidance to materially impact its consolidated financial statements.

(1) Represents the interest rate as of March 31, 2024. All interest rates are payable in cash, unless otherwise noted.

(2) The interest rate on the principal balance outstanding for most of the floating rate loans is indexed to SOFR which typically resets semi-annually, quarterly, or monthly at the borrower's option. The borrower may also elect to have multiple interest reset periods for each loan. For each of these loans, the Company has provided the applicable margin over the reference rates based on each respective credit agreement and the cash interest rate as of period end. As of March 31, 2024, the reference rates for SLF JV I's variable rate loans were the 30-day SOFR at 5.33%, and the 90-day SOFR at 5.31%. Most loans include an interest floor, which generally ranges from 0% to 1%. SOFR based contracts may include a credit spread adjustment that is charged in addition to the base rate and the stated spread.

(3) Represents the current determination of fair value as of March 31, 2024 utilizing a similar technique as the Company in accordance with ASC 820. However, the determination of such fair value is not included in the valuation process described elsewhere herein.

[1] As of March 31, 2024, these investments were categorized as Level 3 within the fair value hierarchy established by Financial Accounting Standards Board ("FASB") guidance under Accounting Standards Codification ("ASC") Topic 820, Fair Value Measurements and Disclosures ("ASC 820").

[2] Investment had undrawn commitments. Unamortized fees are classified as unearned income which reduces cost basis, which may result in a negative cost basis. A negative fair value may result from the unfunded commitment being valued below par.

[3] This investment represents a participation interest in the underlying securities shown.

[4] Principal includes accumulated payment in kind ("PIK") interest and is net of repayments, if any. “£” signifies the investment is denominated in British Pounds. "€" signifies the investment is denominated in Euros. All other investments are denominated in U.S. dollars.

[5] Investment had undrawn commitments. Unamortized fees are classified as unearned income which reduces cost basis, which may result in a negative cost basis. A negative fair value may result from the unfunded commitment being valued below par.

[6] This investment represents a participation interest in the underlying securities shown.

[7] Principal includes accumulated PIK interest and is net of repayments, if any. “£” signifies the investment is denominated in British Pounds. "€" signifies the investment is denominated in Euros. All other investments are denominated in U.S. dollars.

[8] As of September 30, 2023, these investments were categorized as Level 3 within the fair value hierarchy established by ASC 820.

[9] The interest rate on the principal balance outstanding for most of the floating rate loans is indexed to the secured overnight financing rate ("SOFR"), the euro interbank offered rate ("EURIBOR" or "E"), the sterling overnight index average ("SONIA") and/or an alternate base rate (e.g., prime rate), which typically resets semi-annually, quarterly, or monthly at the borrower's option. The borrower may also elect to have multiple interest reset periods for each loan. For each of these loans, the Company has provided the applicable margin over the reference rate based on each respective credit agreement and the cash interest rate as of period end. As of March 31, 2024, the reference rates for the Company's variable rate loans were the 30-day SOFR at 5.33%, the 90-day SOFR at 5.31%, the 180-day SOFR at 5.23%, the PRIME at 8.50%, the SONIA at 5.19% and the 90-day EURIBOR at 3.88%. Most loans include an interest floor, which generally ranges from 0% to 2.75%. SOFR and SONIA based contracts may include a credit spread adjustment that is charged in addition to the base rate and the stated spread.

[10] Interest rates may be adjusted from period to period on certain term loans and revolvers. These rate adjustments may be either temporary in nature due to tier pricing arrangements or financial or payment covenant violations in the original credit agreements or permanent in nature per loan amendment or waiver documents.

[11] The interest rate on the principal balance outstanding for most of the floating rate loans is indexed to SOFR, the London Interbank Offered Rate ("LIBOR" or "L"), SONIA and/or an alternate base rate (e.g., prime rate), which typically resets semi-annually, quarterly, or monthly at the borrower's option. The borrower may also elect to have multiple interest reset periods for each loan.

[1] As of March 31, 2024, these investments were categorized as Level 3 within the fair value hierarchy established by Financial Accounting Standards Board ("FASB") guidance under Accounting Standards Codification ("ASC") Topic 820, Fair Value Measurements and Disclosures ("ASC 820").

[2] Investment had undrawn commitments. Unamortized fees are classified as unearned income which reduces cost basis, which may result in a negative cost basis. A negative fair value may result from the unfunded commitment being valued below par.

[3] This investment represents a participation interest in the underlying securities shown.

[4] Principal includes accumulated payment in kind ("PIK") interest and is net of repayments, if any. “£” signifies the investment is denominated in British Pounds. "€" signifies the investment is denominated in Euros. All other investments are denominated in U.S. dollars.

[5] The interest rate on the principal balance outstanding for most of the floating rate loans is indexed to the secured overnight financing rate ("SOFR"), the euro interbank offered rate ("EURIBOR" or "E"), the sterling overnight index average ("SONIA") and/or an alternate base rate (e.g., prime rate), which typically resets semi-annually, quarterly, or monthly at the borrower's option. The borrower may also elect to have multiple interest reset periods for each loan. For each of these loans, the Company has provided the applicable margin over the reference rate based on each respective credit agreement and the cash interest rate as of period end. As of March 31, 2024, the reference rates for the Company's variable rate loans were the 30-day SOFR at 5.33%, the 90-day SOFR at 5.31%, the 180-day SOFR at 5.23%, the PRIME at 8.50%, the SONIA at 5.19% and the 90-day EURIBOR at 3.88%. Most loans include an interest floor, which generally ranges from 0% to 2.75%. SOFR and SONIA based contracts may include a credit spread adjustment that is charged in addition to the base rate and the stated spread.

[6] Interest rates may be adjusted from period to period on certain term loans and revolvers. These rate adjustments may be either temporary in nature due to tier pricing arrangements or financial or payment covenant violations in the original credit agreements or permanent in nature per loan amendment or waiver documents.

The borrower may also elect to have multiple interest reset periods for each loan. For each of these loans, the Company has provided the applicable margin over the reference rate based on each respective credit agreement and the cash interest rate as of period end. All LIBOR and SOFR shown above is in U.S. dollars unless otherwise noted. As of September 30, 2023, the reference rates for the Company's variable rate loans were the 30-day SOFR at 5.32%, the 90-day SOFR at 5.39%, the 180-day SOFR at 5.47%, the 30-day LIBOR at 5.43%, the 90-day LIBOR at 5.65%, the 180-day LIBOR at 5.90%, the PRIME at 8.50%, the SONIA at 5.19%, the 30-day EURIBOR at 3.42%, the 90-day EURIBOR at 3.82% and the 180-day EURIBOR at 3.95%.

[1] As defined in the Investment Company Act, the Company is deemed to be both an "Affiliated Person" of and to "Control" these portfolio companies as the Company owns more than 25% of the portfolio company's outstanding voting securities or has the power to exercise control over management or policies of such portfolio company (including through a management agreement). See Schedule 12-14 in the Company's annual report on Form 10-K for the year ended September 30, 2023 for transactions during the year ended September 30, 2023 in which the issuer was both an Affiliated Person and a portfolio company that the Company is deemed to control.

[2] Control Investments generally are defined by the Investment Company Act as investments in companies in which the Company owns more than 25% of the voting securities or maintains greater than 50% of the board representation.

[3] As defined in the Investment Company Act, the Company is deemed to be both an "Affiliated Person" of and to "Control" these portfolio companies as the Company owns more than 25% of the portfolio company's outstanding voting securities or has the power to exercise control over management or policies of such portfolio company (including through a management agreement). See Schedule 12-14 in the accompanying notes to the Consolidated Financial Statements for transactions during the six months ended March 31, 2024 in which the issuer was both an Affiliated Person and a portfolio company that the Company is deemed to control.

[4] Control Investments generally are defined by the Investment Company Act of 1940, as amended (the "Investment Company Act"), as investments in companies in which the Company owns more than 25% of the voting securities or maintains greater than 50% of the board representation.

[5] Affiliate Investments generally are defined by the Investment Company Act as investments in companies in which the Company owns between 5% and 25% of the voting securities.

[6] Affiliate Investments generally are defined by the Investment Company Act as investments in companies in which the Company owns between 5% and 25% of the voting securities.

[7] As of March 31, 2024, these investments were categorized as Level 3 within the fair value hierarchy established by Financial Accounting Standards Board ("FASB") guidance under Accounting Standards Codification ("ASC") Topic 820, Fair Value Measurements and Disclosures ("ASC 820").

[8] Investment had undrawn commitments. Unamortized fees are classified as unearned income which reduces cost basis, which may result in a negative cost basis. A negative fair value may result from the unfunded commitment being valued below par.

[9] This investment represents a participation interest in the underlying securities shown.

[10] Principal includes accumulated payment in kind ("PIK") interest and is net of repayments, if any. “£” signifies the investment is denominated in British Pounds. "€" signifies the investment is denominated in Euros. All other investments are denominated in U.S. dollars.

[11] The interest rate on the principal balance outstanding for most of the floating rate loans is indexed to the secured overnight financing rate ("SOFR"), the euro interbank offered rate ("EURIBOR" or "E"), the sterling overnight index average ("SONIA") and/or an alternate base rate (e.g., prime rate), which typically resets semi-annually, quarterly, or monthly at the borrower's option. The borrower may also elect to have multiple interest reset periods for each loan.
