NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

BASIS OF PRESENTATION

The Company follows the accounting and reporting guidance in Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 946, Financial Services — Investment Companies.

In the normal course of business, the Company enters into a variety of undertakings containing a variety of warranties and indemnifications that may expose the Company to some risk of loss. The risk of future loss arising from such undertakings, while not quantifiable, is expected to be remote.

USE OF ESTIMATES

The financial statements have been prepared in accordance with GAAP, which requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results may differ from those estimates, and these differences could be material.

CONSOLIDATION

As provided under Regulation S-X and ASC Topic 946-810, Consolidation (“ASC 946-810”), the Company will generally not consolidate its investment in a company other than a wholly-owned investment company or a controlled operating company whose business consists of providing services to the Company for the periods during which it was held.

CASH AND CASH EQUIVALENTS

Cash consists of deposits held at the Company’s custodian bank. Cash equivalents consist of highly liquid investments, such as money market funds, with original maturities of three months or less. The Company places its cash equivalents with financial institutions and, at times, cash held in bank accounts may exceed the Federal Deposit Insurance Corporation insured limit. Cash equivalents are classified as Level 1 assets and are included on the Company’s schedule of investments. Certain cash equivalents are carried at cost or amortized cost, which approximates fair value, and investments held in money market funds are valued at their net asset value (“NAV”) per share.

INVESTMENT VALUATION

The Company’s Board of Directors determines the fair value of the Company’s investments in accordance with the provisions of ASC 820, Fair Value Measurement (“ASC 820”) and Rule 2a-5 under the 1940 Act (“Rule 2a-5”). Estimates made in the preparation of the Company’s financial statements include the valuation of investments and the related amounts of unrealized appreciation and depreciation of investments recorded. The Company believes that there is no single definitive method for determining fair value in good faith. As a result, determining fair value requires that judgment be applied to the specific facts and circumstances of each portfolio investment while employing a consistently applied valuation process for the types of investments the Company makes. The Board of Directors values the Company’s investments for which market quotations are not readily available at fair value as determined in good faith by the Board on at least a quarterly basis. ASC 820 clarified the definition of fair value and requires companies to expand their disclosure about the use of fair value to measure assets and liabilities in interim and annual periods subsequent to initial recognition.

ASC 820 defines fair value as the price 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. ASC 820-10 also establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include: Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, which includes inputs such as quoted prices for similar securities in active markets and quoted prices for identical securities in markets that are not active; and Level 3, defined as unobservable inputs for which little or no market data exists, therefore requiring an entity to develop its own assumptions. The Company considers the attributes of current market conditions on an on-going basis and has determined that due to the general illiquidity of the market for its investment portfolio, whereby little or no market data exists, all of the Company’s investments are based upon Level 3 inputs as of December 31, 2025 and December 31, 2024.

The Board of Directors determines the value of its investment portfolio each quarter. In connection with that determination, members of Oxford Square Management’s portfolio management team prepare a quarterly analysis of each portfolio investment using the most recent portfolio company financial statements, forecasts and other relevant financial and operational information. The Company has and may continue to engage third-party valuation firms to provide assistance in valuing certain of its syndicated loans and bilateral investments, including related equity investments, although the Board of Directors ultimately determines the appropriate valuation of each such investment. Changes in fair value, as described above, are recorded in the statements of operations as net change in unrealized appreciation/depreciation on investments.

Syndicated Loans (Including Senior Secured Notes)

In accordance with ASC 820, the Company’s valuation procedures specifically provide for the review of indicative quotes supplied by the large agent banks that make a market for each security. However, the marketplace from which the Company obtains indicative bid quotes for purposes of determining the fair value of its syndicated loan investments has shown attributes of illiquidity as described by ASC 820. During such periods of illiquidity, when the Company believes that the non-binding indicative bids received from agent banks for certain syndicated loan investments that it owns may not be determinative of their fair value, or when no market indicative quote is available, the Company has and may continue to engage third-party valuation firms to provide assistance in valuing certain syndicated investments that the Company owns. The third-party valuation firms may use the income or market approach in arriving at a valuation. Unobservable inputs utilized could include discount rates derived from estimated credit spreads and earnings before interest, taxes, depreciation, and amortization (“EBITDA”) multiples. In addition, Oxford Square Management analyzes each syndicated loan by reviewing the portfolio company’s financial statements, covenant compliance and recent trading activity in the security, if known, and other business developments related to the portfolio company. All available information, including non-binding indicative bids which may not be determinative of fair value, is presented to the Company’s Valuation Committee (the “Valuation Committee”) to consider in its determination of fair value. In some instances, there may be limited trading activity in a security even though the market for the security is considered not active. In such cases, the Valuation Committee

will consider the number of trades, the size and timing of each trade, and other circumstances around such trades, to the extent such information is available, in its determination of fair value. The Valuation Committee will evaluate the impact of such additional information, and factor it into its consideration of the fair value that is indicated by the analysis provided by third-party valuation firms, if any. When we receive warrants or other equity securities at nominal or no additional cost in connection with a new syndicated loan investment, or due to a restructuring of an existing investment, the cost basis in the new investments will be allocated between the new debt securities and any such warrants or other equity securities received at the time of origination/restructuring. These investments may be subsequently valued using a multitude of methods, including, but not limited to, intrinsic value methods, Black-Scholes models, and Monte Carlo option pricing models. All information is presented to the Board for its determination of fair value of these investments.

Collateralized Loan Obligations — Debt and Equity

The Company has acquired debt and equity positions in CLO investment vehicles and can purchase CLO warehouse facilities. These investments are special purpose financing vehicles. In valuing such investments, the Company considers the indicative prices provided by a recognized industry pricing service as a primary source, and the implied yield of such prices, supplemented by actual trades executed in the market at or around period-end, as well as the indicative prices provided by the broker who arranges transactions in such investment vehicles. The Company also considers those instances in which the record date for an equity distribution payment falls on or before the last day of the period, and the likelihood that a prospective purchaser would require a downward adjustment to the indicative price representing substantially all of the pending distribution. Additional factors include any available information on other relevant transactions including firm bids and offers in the market and information resulting from bids-wanted-in-competition. In addition, the Company considers the operating metrics of the specific investment vehicle, including compliance with collateralization tests, defaulted and restructured securities, and payment defaults, if any. In periods of illiquidity and volatility, the Company may rely more heavily on other qualities and metrics, including but not limited to, the collateral manager, time left in the reinvestment period, expected cash flows and overcollateralization ratios, instead of the Company’s generated valuation yields. Oxford Square Management or the Valuation Committee may request an additional analysis by a third-party firm to assist in the valuation process of CLO investment vehicles. All information is presented to the Board for its determination of fair value of these investments.

Bilateral Investments (Including Equity)

Bilateral investments (as defined below) for which market quotations are readily available are valued by an independent pricing agent or market maker. If such market quotations are not readily available, under the valuation procedures approved by the Board, upon the recommendation of the Valuation Committee, a third-party valuation firm will prepare valuations for each of the Company’s bilateral investments that, when combined with all other investments in the same portfolio company, have a value as of the previous quarter of greater than or equal to 2.0% of its total assets as of the previous quarter. In addition, in those instances where a third-party valuation is prepared for a portfolio investment which meets the parameters noted above, the frequency of those third-party valuations is based upon the grade assigned to each such security under its credit grading system as follows: Grade 1, at least annually; Grade 2, at least semi-annually; Grades 3, 4, and 5, at least quarterly. Bilateral investments which do not meet the parameters above are not required to have a third-party valuation and, in those instances, a valuation analysis will be prepared by Oxford Square Management. All information is presented to the Board for its determination of fair value of these investments.

The term “Bilateral investments” means debt and equity investments directly negotiated between the Company and a portfolio company, but excludes syndicated loans (i.e., corporate loans arranged by an agent on behalf of a company, portions of which are held by multiple investors in addition to OXSQ).

Refer to “Note 3. Fair Value” in the notes to the Company’s financial statements for more information on investment valuation and the Company’s portfolio of investments.

INVESTMENT INCOME

Interest Income

Interest income is recorded on an accrual basis using the contractual rate applicable to each debt investment and includes the accretion of market discounts and/or original issue discount (“OID”) and amortization of market premiums. Discounts from and premiums to par value on securities purchased are accreted/amortized into interest income over the life of the respective security using the effective yield method. The amortized cost of investments represents the original cost adjusted for the accretion of discounts and amortization of premiums, if any.

Interest income also includes a payment-in-kind (“PIK”) component on certain investments in the Company’s portfolio. Refer to the section below, “Payment-In-Kind,” for a description of PIK income and its impact on interest income.

Payment-In-Kind

The Company has debt and preferred stock investments in its portfolio that contain contractual PIK provisions. PIK interest and preferred stock dividends are computed at their contractual rates and are accrued into income and recorded as interest and dividend income, respectively. The PIK amounts are added to the principal balances on the capitalization dates. Upon capitalization, the PIK portions of the investments are valued at their respective fair values. If the Company believes that a PIK is not fully expected to be realized, the PIK investment would be placed on non-accrual status. When a PIK investment is placed on non-accrual status, the accrued, uncapitalized interest or dividends would be reversed from the related receivable through interest or dividend income, respectively. PIK investments on non-accrual status are restored to accrual status once it becomes probable that such PIK will be ultimately collectible in cash. For the year ended December 31, 2025, approximately $2.9 million of PIK interest was recognized as interest income and approximately $0.3 million of PIK was recognized as other income. For the year ended December 31, 2024, approximately $463,000 of PIK interest was recognized as interest income. For the year ended December 31, 2023, no PIK interest was recognized as interest income. For years ended December 31, 2025, 2024 and 2023, the Company did not recognize dividend income due to PIK on its preferred stock investments.

Income from Securitization Vehicles and Investments

Income from investments in the equity class securities of CLO vehicles (typically income notes or subordinated notes) is recorded using the effective interest method in accordance with the provisions of ASC 325-40, Beneficial Interests in Securitized Financial Assets, based upon estimated cash flows, amounts and timing, including those CLO equity investments that have not made their inaugural distribution for the relevant period end. The Company monitors the expected residual payments, and effective yield is determined and updated periodically, as needed. Accordingly, investment income recognized on CLO equity securities in the statements of operations differs from both the tax-basis investment income and from the cash distributions actually received by the Company during the period.

The Company also records income on its investments in CLO warehouse facilities based on a stated rate per the underlying note purchase agreement plus accrued interest or, if there is no stated rate, then an estimated rate is calculated using a base case model projecting the timing of the ramp-up of the CLO warehouse facility. For the years ended December 31, 2025, 2024 and 2023, no income was recognized related to CLO warehouse facilities. As of December 31, 2025, 2024 and 2023, the Company did not hold any investments in CLO warehouse facilities.

Other Income

Other income includes prepayment, amendment, and other fees earned by the Company’s loan investments, distributions from fee letters and success fees associated with portfolio investments. Distributions from fee letters are an enhancement to the return on a CLO equity investment and are based upon a percentage of the collateral manager’s fees above the amortized cost, and are recorded as other income when earned. The Company may also earn success fees associated with its investments in certain securitization vehicles or CLO warehouse facilities, which are contingent upon a repayment of the warehouse by a permanent CLO securitization structure; such fees are earned and recognized when the repayment is completed. The Company also earns other income on its cash equivalents balance, which represents cash invested in a money market fund.

Preferred Stock Dividends

The Company holds preferred stock investments in its portfolio that contain cumulative preferred dividends that accumulate quarterly. The Company will generally record cumulative preferred dividends as investment income when they are received or declared by the portfolio company’s board of directors or upon any voluntary or involuntary liquidation, dissolution or winding up of the portfolio company, and are collectible. As of December 31, 2025, the Company’s preferred equity investments in one of its portfolio companies were on non-accrual status, which had an aggregate fair value of approximately $5.0 million. There were no cumulative preferred dividends recorded as dividend income during the years ended December 31, 2025, 2024 and 2023, as the Company deemed them to be uncollectible.

Non-Accrual Investments

Investments are generally placed on non-accrual status when there is reasonable doubt that principal or interest or dividends will be collected in full and the Company will generally cease recognizing interest or dividend income on that investment for financial reporting purposes until all principal and interest or dividends have been brought current through payment or due to restructuring such that the interest or dividend income is deemed to be collectible. The Company generally restores non-accrual investments to accrual status when past due principal and interest or dividend is paid and, in the Company’s judgment, is likely to remain current. As of December 31, 2025, the Company did not have any debt investments that were on non-accrual status. As of December 31, 2024, the Company had one debt investment that was on non-accrual status. As of December 31, 2023, the Company had four debt investments that were on non-accrual status. As of December 31, 2025, 2024, and 2023, the Company had three preferred stock investments in one portfolio company that were on non-accrual status.

DEFERRED DEBT ISSUANCE COSTS

Deferred debt issuance costs consist of fees and expenses incurred in connection with the closing or amending of credit facilities and debt offerings, and are capitalized at the time of payment. These costs are amortized using the straight line method over the terms of the respective credit facilities and debt securities. The amortized expenses are included in interest expense in the Company’s financial statements. The unamortized deferred debt issuance costs are included on the Company’s statements of assets and liabilities as a direct deduction from the related debt liability. Upon early termination or partial principal pay down of debt, or a credit facility, the unamortized costs related to such debt are accelerated into realized losses on extinguishment of debt on the Company’s statements of operations.

EQUITY OFFERING COSTS

Equity offering costs consist of fees and expenses incurred in connection with the registration and public offer and sale of the Company’s common stock, including legal, accounting and printing fees. These costs are deferred at the time of incurrence and are subsequently charged as a reduction to capital when the offering takes place or as shares are issued. Deferred costs are periodically reviewed and expensed if the related registration is no longer active.

SHARE REPURCHASES

From time to time, the Board may authorize a share repurchase program under which shares are purchased in open market transactions. Since the Company is incorporated in Maryland, MGCL requires share repurchases to be accounted for as a share retirement. The cost of repurchased shares is charged against capital on the settlement date.

On October 30, 2025, the Board of Directors authorized a 12-month share repurchase program (the “Share Repurchase Program”). Under the Share Repurchase Program, the Company may repurchase, during the 12-month period commencing on October 30, 2025, up to $25.0 million in the aggregate of the Company’s outstanding common stock in the open market. The timing, manner, price and amount of any share repurchases will be determined by the Company, in its discretion, based upon the evaluation of economic and market conditions, the Company’s stock price, applicable legal, contractual and regulatory requirements and other factors. The Share Repurchase Program is expected to be in effect until October 30, 2026, unless extended or until the aggregate repurchase amount has been expended. The Share Repurchase Program does not require the Company to repurchase any specific number of shares, and the Company cannot assure stockholders that any shares will be repurchased under the Share Repurchase Program. The Share Repurchase Program may be suspended, extended, modified or discontinued at any time. During the year ended December 31, 2025, no shares were repurchased under the Share Repurchase Program.

During the years ended December 31, 2024, and 2023 the Company was not authorized to repurchase any shares of outstanding common stock.

SECURITIES TRANSACTIONS

Securities transactions are recorded on the trade date. Realized gains and losses on investments sold are recorded on the basis of specific identification. An optional redemption (“optionally redeemed”) feature of a CLO allows a majority of the holders of the equity securities issued by the CLO issuer, after the end of a specified non-call period, to cause the redemption of the secured notes issued by the CLO with proceeds paid either through the liquidation of the CLO’s assets or through a refinancing with new debt. The optional redemption is effectively a voluntary prepayment of the secured debt issued by the CLO prior to the stated maturity of such debt. Distributions received on CLO equity investments where the optional redemption feature has been exercised are first applied to the remaining cost basis until it is reduced to zero, after which distributions are recorded as realized gains.

U.S. FEDERAL INCOME TAXES

The Company intends to operate so as to qualify to be taxed as a RIC under Subchapter M of the Code and, as such, to not be subject to U.S. federal income tax on the portion of its taxable income and gains timely distributed to stockholders. To qualify for RIC tax treatment, OXSQ is required to distribute at least 90% of its investment company taxable income annually, meet certain source-of-income requirements annually and certain diversification requirements quarterly and file Form 1120-RIC, as defined by the Code.

Because U.S. federal income tax regulations differ from GAAP, distributions in accordance with tax regulations may differ from net investment income and realized gains recognized for financial reporting purposes. Differences may be permanent or temporary. Permanent differences are reclassified among capital accounts in the financial statements to reflect their tax character. Temporary differences arise when certain items of income, expense, gain or loss are recognized at some time in the future. Differences in classification may also result from the treatment of short-term gains as ordinary income for tax purposes.

The Company recognizes the tax benefits of uncertain tax positions only when the position is more likely than not to be sustained, assuming examination by tax authorities. Through December 31, 2025, management has analyzed the Company’s tax positions and concluded that no liability for unrecognized tax benefits should be

recorded related to uncertain tax positions expected to be taken in the Company’s 2025 tax returns. The Company identifies its major tax jurisdictions as U.S Federal and the state of Connecticut. The Company did not have any uncertain tax positions that met the recognition measurement criteria of ASC 740-10-25, Income Taxes, nor did the Company have any unrecognized tax benefits as of the periods presented herein. The Company files tax returns with the Internal Revenue Service and the state of Connecticut. Generally, each of the tax years in the four-year period ended December 31, 2025 remains subject to examination by taxing authorities.

For tax purposes, the cost basis of the portfolio investments as of December 31, 2025 and 2024, was approximately $395,691,951 and $393,395,734, respectively.

NOTE 3. FAIR VALUE

The Company’s assets measured at fair value by investment type on a recurring basis as of December 31, 2025 were as follows:

The Company’s assets measured at fair value by investment type on a recurring basis as of December 31, 2024 were as follows:

Significant Unobservable Inputs for Level 3 Investments

The following tables provide quantitative information about the Company’s Level 3 fair value measurements as of December 31, 2025 and December 31, 2024, respectively. The Company’s Valuation Policy, which was previously approved by the Board, establishes parameters for the sources and types of valuation analysis, as well as the methodologies and inputs that the Company uses in determining fair value. If the Valuation Committee or Oxford Square Management determines that additional techniques, sources or inputs are appropriate or necessary in a given situation, such additional analysis will be undertaken. The tables, therefore, are not all-inclusive, but provide information on the significant Level 3 inputs that are pertinent to the Company’s fair value measurements. The weighted average calculations in the tables below are based on fair values for all debt related calculations and CLO equity.

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

(2) The impact on the fair value measurement of an increase in each unobservable input is in isolation. The discount rate is the rate used to discount future cash flows in a discounted cash flow calculation. An increase in the discount rate, in isolation, would result in a decrease in the fair value measurement. Market Multiples/EBITDA refer to the input (often derived from the value of a comparable company) that is multiplied by the historic and/or expected EBITDA of a company in order to estimate the company’s value. An increase in the Market Multiples/EBITDA, in isolation, would result in an increase in the fair value measurement.

(3) The Company generally uses prices provided by an independent pricing service, or broker or agent bank non-binding indicative bid prices (“NBIB”), on or near the valuation date as the primary basis for the fair value determinations for syndicated notes, and CLO debt and equity investments, which may be adjusted for pending equity distributions as of valuation date. These bid prices are non-binding and may not be determinative of fair value. Each bid price is evaluated by the Valuation Committee in conjunction with additional information compiled by Oxford Square Management, including financial performance, recent business developments, and, in the case of CLO debt and equity investments, performance and covenant compliance information as provided by the independent trustee.

(4) The calculation of weighted average for a range of values, for a single investment within a given asset category, is not considered to provide a meaningful representation (“ncm”).

(5) The Company calculates the fair value of certain CLO equity investments based upon the net present value of expected contractual payment streams discounted using estimated market yields for the equity tranche of the respective CLO vehicle. The Company also considers those investments in which the record date for an equity distribution payment falls on or before the last day of the period, and the likelihood that a prospective purchaser would require an adjustment to the transaction price representing substantially all of the pending distribution.

(6) Discount rate represents the rate at which future cash flows are discounted to calculate a present value, reflecting market assumptions for risk.

(7) Enterprise value is defined as the total value of a company, including debt and cash. For senior secured notes and equity investments, third-party valuation firms evaluate the financial and operational information of the portfolio companies that the Company provides to them, as well as independent market and industry information that they consider appropriate in forming an opinion as to the fair value of the Company’s securities. In those instances where the carrying value and/or internal credit rating of the investment does not require the use of a third-party valuation firm, a valuation is prepared by Oxford Square Management, which may include liquidation analysis or which may utilize a subsequent transaction to provide an indication of fair value.

(8) EBITDA, or earnings before interest expense, taxes, depreciation and amortization, is an unobservable input which is generally based on the most recently available twelve-month financial statements provided by the portfolio company. Market multiples, also an unobservable input, represent an estimation of where market participants might value an enterprise based upon information available for comparable companies in the market. “LTM” refers to “last twelve months.”

(9) The fair value of those CLO equity positions which have been optionally redeemed are generally valued using a liquidation net asset value basis which represents the estimated expected residual value of the CLO as of the end of the period.

(10) Prices provided by independent pricing services are evaluated in conjunction with actual trades and payoffs and, in certain cases, the value represented by actual trades or payoffs may be more representative of fair value as determined by the Valuation Committee.

(11) Totals may not sum due to rounding.

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

(2) The impact on the fair value measurement of an increase in each unobservable input is in isolation. The discount rate is the rate used to discount future cash flows in a discounted cash flow calculation. An increase in the discount rate, in isolation, would result in a decrease in the fair value measurement. Market Multiples/EBITDA refer to the input (often derived from the value of a comparable company) that is multiplied by the historic and/or expected EBITDA of a company in order to estimate the company’s value. An increase in the Market Multiples/EBITDA, in isolation, would result in an increase in the fair value measurement.

Financial Instruments Disclosed, But Not Carried, At Fair Value

The following table presents the carrying value and fair value of the Company’s financial liabilities disclosed, but not carried, at fair value as of December 31, 2025, and the level of each financial liability within the fair value hierarchy:

(1) Carrying value is net of unamortized deferred debt issuance costs. Unamortized deferred debt issuance costs associated with the 5.50% Unsecured Notes totaled approximately $1.0 million as of December 31, 2025. Unamortized deferred debt issuance costs associated with the 7.75% Unsecured Notes totaled approximately $2.6 million as of December 31, 2025.

(2) For the 5.50% Unsecured Notes and 7.75% Unsecured Notes, fair value is based upon the closing price on the last day of the period. The 5.50% Unsecured Notes and 7.75% Unsecured Notes are listed on the NASDAQ Global Select Market (trading symbol “OXSQG” and “OXSQH”, respectively).

The following table presents the carrying value and fair value of the Company’s financial liabilities disclosed, but not carried, at fair value as of December 31, 2024, and the level of each financial liability within the fair value hierarchy:

(1) Carrying value is net of unamortized deferred debt issuance costs. Unamortized deferred debt issuance costs associated with the 6.25% Unsecured Notes totaled approximately $0.3 million as of December 31, 2024. Unamortized deferred debt issuance costs associated with the 5.50% Unsecured Notes totaled approximately $1.4 million as of December 31, 2024.

(2) For the 6.25% Unsecured Notes and 5.50% Unsecured Notes, fair value is based upon the closing price on the last day of the period. The 6.25% Unsecured Notes were listed on the NASDAQ Global Select Market (trading symbol “OXSQZ”) until they were fully repaid and delisted from the NASDAQ Global Select Market on September 19, 2025. The 5.50% Unsecured Notes are listed on the NASDAQ Global Select Market (trading symbol “OXSQG”).

A reconciliation of thefair value of investments for the year ended December 31, 2025, utilizing significant unobservable inputs, is as follows:

(1) Reduction to CLO equity cost value of approximately $7.7 million represented the distributions received, or entitled to be received, on the Company’s investments held in CLO equity subordinated and income notes of approximately $24.1 million, plus the amortization of cost of the Company’s CLO fee notes of approximately $57,000, less the effective yield interest income recognized on the Company’s CLO equity subordinated and income notes of approximately $16.5 million.

A reconciliation of the fair value of investments for the year ended December 31, 2024, utilizing significant unobservable inputs, is as follows:

(1) Reduction to CLO equity cost value of approximately $13.0 million represented the distributions received, or entitled to be received, on the Company’s investments held in CLO equity subordinated and income notes of approximately $28.4 million, plus the amortization of cost of the Company’s CLO fee notes of approximately $71,000, less the effective yield interest income recognized on the Company’s CLO equity subordinated and income notes of approximately $15.4 million.

The following table shows the fair value of the Company’s portfolio of investments by asset class as of December 31, 2025 and 2024:

NOTE 7. RELATED PARTY TRANSACTIONS

The Company pays Oxford Square Management a fee for its services under the Investment Advisory Agreement consisting of — a base investment advisory fee (the “Base Fee”) based on its gross assets, as described below, and two types of incentive fees. The cost of both the Base Fee and any incentive fees earned by Oxford Square Management are ultimately borne by the Company’s common stockholders.

As described in greater detail under Item 1. Business — Investment Advisory Agreement — Advisory Fee in this Annual Report on Form 10-K for the year ended December 31, 2025, the Company first calculates the Base Fee and any incentive fee under the terms of the Investment Advisory Agreement, then calculates the Base Fee and any incentive fee under the terms of the fee waiver letter unilaterally adopted by Oxford Square Management, effective April 1, 2016 (the “2016 Fee Waiver”), and, finally, adopts the lower of two combined results as the total fees payable to Oxford Square Management.

Base Fee

The Base Fee is payable quarterly in arrears, calculated based on a percentage of the average value of the Company’s gross assets at the end of the two most recently completed calendar quarters, and appropriately prorated for any partial quarter. Accordingly, the Base Fee will be payable regardless of whether the value of the Company’s gross assets has decreased during the quarter.

Under the terms of the Investment Advisory Agreement, the Base Fee is calculated at an annual rate of 2.00%, and appropriately adjusted for any equity or debt capital raises, repurchases, or redemptions during the current calendar quarter.

Under the terms of the 2016 Fee Waiver, for the purpose of calculating the amount of total advisory fees (if any) to be waived during a particular calendar quarter, the Base Fee (as a portion of the total calculation) is calculated at an annual rate of 1.50%, and adjusted pro rata for any share issuances, debt issuances, repurchases or redemptions during the current calendar quarter; provided, however, that no Base Fee is payable on the cash proceeds received by the Company in connection with any share or debt issuances until such proceeds have been invested in accordance with the Company’s investment objectives.

The following table represents the portion of the total advisory fee ascribed to the Base Fee (pursuant to the 2016 Fee Waiver calculation) for the years ended December 31, 2025, 2024 and 2023, respectively:

The Base Fee payable to Oxford Square Management as of December 31, 2025 and 2024 was approximately $1.0 million and $1.2 million, respectively.

Incentive Fee

The incentive fees are commonly referred to as the “Income Incentive Fee” and the “Capital Gains Incentive Fee,” with the first fee payable quarterly in arrears and the second fee payable in arrears at the end of each calendar year.

Net Investment Income Incentive Fee

The first fee (the “Net Investment Income Incentive Fee”), is determined by reference to the Company’s “Pre-Incentive Fee Net Investment Income” (as defined below). Given that this incentive fee is payable without regard to any gain, loss or unrealized depreciation that may occur during the quarter, Oxford Square Management’s incentive fee may be payable notwithstanding a decline in net asset value that quarter.

Under the terms of the Investment Advisory Agreement, the Net Investment Income Incentive Fee is calculated based on the Company’s “Pre-Incentive Fee Net Investment Income” for the immediately preceding calendar quarter.

• 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) accrued during the calendar quarter minus the Company’s operating expenses for the quarter (including the Base 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 original issue discount, debt instruments with PIK interest, and zero-coupon securities), accrued income that we have 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.

• Pre-Incentive Fee Net Investment Income, expressed as a rate of return on the value of the Company’s net assets at the end of the immediately preceding calendar quarter, is compared to one-fourth of an annual “hurdle rate.” The annual hurdle rate is determined as of the immediately preceding December 31 st by adding 5.0% to the interest rate then payable on the most recently issued five-year U.S. Treasury Notes, up to a maximum annual hurdle rate of 10.0%. The annual hurdle rates for the 2025, 2024 and 2023 calendar years, calculated as of the immediately preceding December 31, were 9.38%,8.84%, and 8.99%, respectively, under the terms of the Investment Advisory Agreement. The Company’s net investment income (to the extent not distributed to stockholders) used to calculate the Net Investment Income Incentive Fee was also included in the amount of gross assets used to calculate the 2% Base Fee.

a. The operation of the incentive fee with respect to the Company’s Pre-Incentive Fee Net Investment Income for each quarter is as follows:

i. no incentive fee is payable to Oxford Square Management in any calendar quarter in which the Pre-Incentive Fee Net Investment Income does not exceed one fourth of the annual hurdle rate (9.38% for the 2025 calendar year).

ii. 20% of the amount of the Pre-Incentive Fee Net Investment Income, if any, that exceeds one-fourth of the annual hurdle rate (9.38% for the 2025 calendar year) in any calendar quarter is payable to Oxford Square Management (i.e., once the hurdle rate is reached,20% of all Pre-Incentive Fee Net Investment Income thereafter will be allocated to Oxford Square Management).

Under the terms of the 2016 Fee Waiver, for the purpose of calculating the amount of total advisory fees (if any) to be waived during a particular calendar quarter, the Income Incentive Fee (as a portion of the total calculation) is calculated based on the amount by which (x) the “Pre-Incentive Fee Net Investment Income” (as defined below) for the calendar quarter exceeds (y) the “Preferred Return Amount” (as defined below) for the calendar quarter.

a. A “Preferred Return Amount” is calculated on a quarterly basis by multiplying 1.75% by the Company’s net asset value at the end of the immediately preceding calendar quarter.

b. The Net Investment Income Incentive Fee is then calculated as follows:

(a) no Net Investment Income Incentive Fee is payable to Oxford Square Management in any calendar quarter in which the “Pre-Incentive Fee Net Investment Income” does not exceed the “Preferred Return Amount”;

(b) 100% of the “Pre-Incentive Fee Net Investment Income” for such quarter, if any, that exceeds the “Preferred Return Amount” but is less than or equal to a “Catch-Up Amount” determined on a quarterly basis by multiplying 2.1875% by OXSQ’s net asset value at the end of such calendar quarter; and

(c) for any quarter in which the “Pre-Incentive Fee Net Investment Income” exceeds the “Catch-Up Amount,” the Net Investment Income Incentive Fee will be 20% of the amount of the “Pre-Incentive Fee Net Investment Income” for such quarter.

c. There is no accumulation of amounts from quarter to quarter for the “Preferred Return Amount,” and accordingly there is no claw back of amounts previously paid to Oxford Square Management if the “Pre-Incentive Fee Net Investment Income” for subsequent quarters is below the quarterly “Preferred Return Amount,” and there is no delay of payment of incentive fees to Oxford Square Management if the “Pre-Incentive Fee Net Investment Income” for prior quarters is below the quarterly “Preferred Return Amount” for the quarter for which the calculation is being made.

d. The calculation of the Company’s Net Investment Income Incentive Fee is subject to a total return requirement that provides that a Net Investment Income Incentive Fee will not be payable to Oxford Square Management except to the extent 20% of the “cumulative net increase in net assets resulting from operations” (which is the amount, if positive, of the sum of the “Pre-Incentive Fee Net Investment Income,” realized gains and losses and unrealized appreciation and depreciation) during the calendar quarter for which such fees are being calculated and the eleven (11) preceding quarters exceeds the cumulative Net Investment Income Incentive Fees accrued and/or paid for such eleven (11) preceding quarters.

In the event that the advisory fee calculations under the 2016 Fee Waiver produce a higher combined Base Fee and Net Investment Income Incentive Fee for any quarterly period, the combined fees are set to the original (lower) level, calculated pursuant to the Investment Advisory Agreement. In the event that advisory fee calculations under the 2016 Fee Wavier produce a lower combined Base Fee and Net Investment Income Incentive Fee for that quarterly period, those lower combined fees are adopted for that quarterly period. In either case, the lower level of combined fees is used for that quarter, and, accordingly, the advisory fee payable to Oxford Square Management can only be reduced, and never increased, as a result of the 2016 Fee Waiver.

The following table represents the portion of the total advisory fee ascribed to Net Investment Income Incentive Fees (pursuant to the 2016 Fee Waiver calculation) for each of the years ended December 31, 2025, 2024 and 2023, respectively:

There was no Net Investment Income Incentive Fee payable to Oxford Square Management as of December 31, 2025 and 2024.

Capital Gains Incentive Fee

The Capital Gains Incentive Fee, which is calculated identically under the Investment Advisory Agreement and under the 2016 Fee Waiver, is determined and payable in arrears as of the end of each calendar year (or upon termination of the Investment Advisory Agreement, as of the termination date), and equals 20% of the Company’s “Incentive Fee Capital Gains,” which consists of its realized capital gains for each calendar year, computed net of all realized capital losses and unrealized capital depreciation for that calendar year. For accounting purposes only, in order to reflect the theoretical Capital Gains Incentive Fee that would be payable for a given period as if all unrealized gains were realized, the Company will accrue a Capital Gains Incentive Fee based upon net realized gains and unrealized depreciation for that calendar year (in accordance with the terms of the Investment Advisory Agreement), plus unrealized appreciation on investments held at the end of the period. It should be noted that a fee so calculated and accrued would not necessarily be payable under the Investment Advisory Agreement and may never be paid based upon the computation of Capital Gains Incentive Fees in subsequent periods. Amounts paid under the Investment Advisory Agreement will be consistent with the formula reflected in the Investment Advisory Agreement.

The amount of Capital Gains Incentive Fee expense related to the hypothetical liquidation of the portfolio (and assuming no other changes in realized or unrealized gains and losses) would only become payable to Oxford Square Management in the event of a complete liquidation of the Company’s portfolio as of period end and the termination of the Investment Advisory Agreement on such date. Also, it should be noted that the Capital Gains Incentive Fee expense fluctuates with the Company’s overall investment results.

There were no Capital Gains Incentive Fees based on hypothetical liquidation for the years ended December 31, 2025, 2024 and 2023. There were no accrued Capital Gains Incentive Fees payable to Oxford Square Management as of December 31, 2025 and 2024.

Administration Agreement

The Company has also entered into the Administration Agreement with Oxford Funds under which Oxford Funds provides administrative services for the Company. The Company pays Oxford Funds an allocable portion of overhead and other expenses incurred by Oxford Funds on its behalf under the Administration Agreement, including a portion of the rent and the compensation of the Chief Financial Officer, accounting staff and other administrative support personnel, which creates potential conflicts of interest that the Board must monitor. The Company also reimburses Oxford Funds for the costs associated with the functions performed by the Company’s Chief Compliance Officer that Oxford Funds pays on the Company’s behalf pursuant to the terms of an agreement between the Company and ACA Group, LLC.

Oxford Square Management is controlled by Oxford Funds, its managing member. Charles M. Royce, a member of the Board, holds a minority, non-controlling interest in Oxford Square Management. Oxford Funds manages the business and internal affairs of Oxford Square Management. Jonathan H. Cohen, the Company’s Chief Executive Officer, as well as a Director, is the Chief Executive Officer of Oxford Square Management and managing member of Oxford Funds. Saul B. Rosenthal, the Company’s President and Chief Operating Officer, is also the President and Chief Operating Officer of Oxford Square Management and a member of Oxford Funds. Messrs. Cohen and Rosenthal together control the equity interests in Oxford Funds.

For the years ended December 31, 2025, 2024 and 2023, the Company incurred approximately $950,000, $747,000 and $825,000, respectively, in compensation expenses for the services of employees allocated to the administrative activities of the Company, pursuant to the Administration Agreement with Oxford Funds. In addition, the Company incurred approximately $58,000, $55,000, and $63,000 for facility costs allocated under the Administration Agreement for the years ended December 31, 2025, 2024 and 2023, respectively. As of December 31, 2025, there were approximately $26,000 of compensation expenses and less than $1,000 of facility costs payable under the Administration Agreement. As of December 31, 2024, there wereno amounts payable under the Administration Agreement.

Co-Investment Exemptive Relief

On January 6, 2026, the Company received an updated form of co-investment exemptive relief from the SEC to allow certain managed funds and investment vehicles, each of whose investment adviser is Oxford Square Management or an investment adviser controlling, controlled by or under common control with Oxford Square Management, to participate in negotiated co-investment transactions where doing so is consistent with regulatory requirements and other pertinent factors, and pursuant to the conditions of the exemptive relief (the “Co-Investment Order”). The Co-Investment Order, which supersedes the co-investment order issued to the Company on June 14, 2017, is a new form of co-investment exemptive relief that adopts a more flexible requirement that allocations be “fair and equitable” to the Company and that Oxford Square Management considers the interests of the Company and other affiliated 1940 Act-regulated funds that rely on the Co-Investment Order in allocations and which minimizes certain board approval requirements as compared to the prior form of co-investment exemptive relief. Among other things, under the Co-Investment Order, the terms, conditions, price, class of securities to be purchased in respect of a particular investment, the date on which such investment is to be made and any registration rights applicable thereto, must be generally the same for the Company and each other participating affiliated entity. The requirements of the Co-Investment Order (including any requirements for board approval thereunder), as well as other regulatory requirements associated with the Company and other affiliated 1940 Act-regulated funds that rely on the Co-Investment Order, potentially will impact the investment allocations among participating entities (including, for the avoidance of doubt, the Company) or otherwise impact allocation results. Any changes to the Co-Investment Order or the rules and other guidance promulgated by the SEC and its staff under the 1940 Act could impact allocations made available to the Company and thereby affect (and potentially decrease) the allocation made to us or otherwise impact the process for allocations in transactions in which the Company participates.

The following table sets forth the components of investment income for the years ended December 31, 2025, 2024 and 2023, respectively:

(1) For the year ended December 31, 2025, the Company earned approximately $327,000 of PIK fees.

The 1940 Act requires that a BDC offer significant managerial assistance to its portfolio companies. The Company may receive fee income for managerial assistance it renders to portfolio companies in connection with its investments. For the years ended December 31, 2025, 2024 and 2023, the Company receivedno fee income for managerial assistance.

NOTE 9. COMMITMENTS AND CONTINGENCIES

In the normal course of business, the Company enters into a variety of undertakings containing a variety of warranties and indemnifications that may expose the Company to some risk of loss. The risk of future loss arising from such undertakings, while not quantifiable, is expected to be remote. As of December 31, 2025, the Company did not have any commitments to purchase additional debt investments.

The Company is not currently subject to any material legal proceedings. From time to time, the Company may be a party to certain legal proceedings in the ordinary course of business, including proceedings relating to the enforcement of the Company’s rights under contracts with its portfolio companies. While the outcome of these legal proceedings, if any, cannot be predicted with certainty, the Company does not expect that these proceedings will have a material effect upon its results of operations and financial condition.

NOTE 11. DISTRIBUTIONS

The Company intends to continue to operate so as to qualify to be taxed as a RIC under the Code and, as such, the Company would not be subject to federal income tax on the portion of its taxable income and gains distributed to stockholders. To qualify to be taxed as a RIC, the Company is required, among other requirements, to distribute at least 90% of its annual investment company taxable income, as defined by the Code. The amount to be paid out as a distribution each quarter is determined by the Board and is based upon the annual taxable income estimated by the management of the Company. Income calculated in accordance with U.S. federal income tax regulations differs substantially from GAAP income. To the extent that the Company’s cumulative undistributed taxable earnings fall below the amount of distributions declared, however, a portion of the total amount of the Company’s distributions for the fiscal year may be deemed a return of capital for tax purposes to the Company’s stockholders.

During the reporting period, the Company adopted the Financial Accounting Standards Board (FASB) Accounting Standards Update 2023-09-Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The adoption of this new standard did not have a material impact to financial statement disclosures and did not affect the Company’s financial positions or results of its operations. The Company did not pay any federal or state income taxes, as it is taxed as a RIC. There were no income taxes paid in foreign jurisdictions by the Company during the reporting period ended December 31, 2025. The Company’s federal and state income tax returns and federal excise tax returns, for which the applicable statutes of limitations have not expired, are subject to examination by the Internal Revenue Service and state departments of revenue.

The Company intends to comply with the applicable provisions of the Code pertaining to RICs to make distributions of taxable income sufficient to relieve it of substantially all federal income taxes. The Company, at its discretion, may carry forward taxable income in excess of calendar year distributions and pay a 4% excise tax on such income.

GAAP requires adjustments to certain components of net assets to reflect permanent differences between financial and tax reporting. These reclassifications have no effect on net asset value per share. For the years ended December 31, 2025, 2024 and 2023, the permanent differences between financial and tax reporting are noted below. These adjustments were the result of book/tax differences in the treatment of unscheduled prepayments, defaulted bonds, extinguishment fees, the treatment of CLO equity investments, and non-deducible excise tax paid.

The Company has adopted an “opt out” distribution reinvestment plan for its common stockholders. As a result, if the Company makes a cash distribution, then stockholders’ cash distributions will be automatically reinvested in additional shares of its common stock, unless they specifically “opt out” of the distribution reinvestment plan so as to receive cash distributions. During the years ended December 31, 2025, 2024 and 2023, the Company issued 391,246,326,184 and 309,016 shares, respectively, of common stock to stockholders for approximately $0.8 million, $0.9 million, and $0.9 million, respectively, in connection with the distribution reinvestment plan. During the year ended December 31, 2025, the Company’s dividend administrator purchased 104,885 shares in the open market to satisfy the reinvestment portion of the Company’s dividends for approximately $184,000. During the years ended 2024 and 2023, the Company’s dividend administrator did not purchase any shares in the open market to satisfy the reinvestment portion of the Company’s dividends.

However, the timing and character of distributions for federal income tax purposes (which are determined in accordance with the U.S. federal tax rules which may differ from GAAP) may be materially different than the historical information the Company used in providing the estimates herein. The final determination of the source of all distributions in 2025 will be made after year-end and the amounts represented may be materially different from the amounts disclosed in the final Form 1099-DIV notice. The actual amounts and sources of the amounts for tax reporting purposes may be subject to change based on tax regulations.

As of December 31, 2025, 2024 and 2023, the estimated components of distributable earnings/(accumulated losses) on a tax basis were as follows:

From time to time, the Board may authorize a share repurchase program under which shares are purchased in open market transactions. Since the Company is incorporated in Maryland, MGCL requires share repurchases to be accounted for as a share retirement. The cost of repurchased shares is charged against capital on the settlement date.

On October 30, 2025, the Board of Directors authorized a 12-month Share Repurchase Program. Under the Share Repurchase Program, the Company may repurchase, during the 12-month period commencing on October 30, 2025, up to $25.0 million in the aggregate of the Company’s outstanding common stock in the open market. The timing, manner, price and amount of any share repurchases will be determined by the Company, in its discretion, based upon the evaluation of economic and market conditions, the Company’s stock price, applicable legal, contractual and regulatory requirements and other factors. The Share Repurchase Program is expected to be in effect until October 30, 2026, unless extended or until the aggregate repurchase amount has been expended. The Share Repurchase Program does not require the Company to repurchase any specific number of shares, and the Company cannot assure stockholders that any shares will be repurchased under the Share Repurchase Program. The Share Repurchase Program may be suspended, extended, modified or discontinued at any time. During the year ended December 31, 2025, no shares were repurchased under the Share Repurchase Program.

During the years ended December 31, 2024, and 2023 the Company was not authorized to repurchase any shares of outstanding common stock.

NOTE 17. RECENT ACCOUNTING PRONOUNCEMENTS

In November 2024, the FASB issued ASU 2024-03, “Income Statement — Reporting Comprehensive Income — Expense Disaggregation Disclosures” (“ASU 2024-03”), which requires public business entities to disclose disaggregated expense details in their income statements, including categories such as employee compensation, depreciation, and amortization. The update aims to enhance transparency by requiring tabular disclosures and qualitative descriptions for unspecified amounts. Additionally, entities must report total selling expenses and their definitions annually. The standard is effective for annual periods beginning after December 15, 2026, with interim periods following in 2027, and early adoption is permitted. The Company is currently assessing the impact of this guidance, however, the Company does not expect a material impact on its financial statements. Other than the aforementioned guidance, the Company’s management does not believe that any recently issued, but not yet effective, accounting standards, if currently adopted, would have a material effect on the accompanying financial statements.
