Summary of Significant Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	NOTE 3. 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 of Directors 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 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 March 31, 2026 and December 31, 2025. 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. The Company may also value a recently purchased investment at cost, unless such valuation, in the judgement of the Valuation Committee, does not represent fair value. 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 4. 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 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 three months ended March 31, 2026, approximately $787,000 of PIK interest was recognized as interest income. For the three months ended March 31, 2025, approximately $708,000 of PIK interest was recognized as interest income and approximately $131,000 of PIK was recognized as other income. For the three months ended March 31, 2026 and 2025, the Company did not recognize PIK dividend income 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 three months ended March 31, 2026 and 2025, no income was recognized related to CLO warehouse facilities. As of March 31, 2026 and December 31, 2025, 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 March 31, 2026, 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 $5.2 million. 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 three months ended March 31, 2026 and 2025, 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 March 31, 2026, the Company had one debt investment that was on non-accrual status. As of December 31, 2025, the Company did not have any debt investments 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 on debt offerings are included on the Company’s statements of assets and liabilities as a direct deduction from the related debt liability, whereas unamortized deferred debt issuance costs associated with credit facilities, if any, are included within other assets. 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, audit 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. As of March 31, 2026 and December 31, 2025, no shares were repurchased under the Share Repurchase Program. 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. In the event a redeemed CLO indenture is discharged, any remaining cost after applying any final cash payment will be recorded as a realized loss. 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, the Company 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 March 31, 2026, 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 or 2026 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 last three tax returns filed remains subject to examination by taxing authorities. For tax purposes, the cost basis of the portfolio investments as of March 31, 2026 and December 31, 2025, was approximately $383,076,273 and $395,691,951, respectively. 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.

Summary of Significant Accounting Policies [Abstract]

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

NOTE 3. 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 of Directors 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 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 March 31, 2026 and December 31, 2025.

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.

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.

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. The Company may also value a recently purchased investment at cost, unless such valuation, in the judgement of the Valuation Committee, does not represent fair value. 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 4. 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 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 three months ended March 31, 2026, approximately $787,000 of PIK interest was recognized as interest income. For the three months ended March 31, 2025, approximately $708,000 of PIK interest was recognized as interest income and approximately $131,000 of PIK was recognized as other income. For the three months ended March 31, 2026 and 2025, the Company did not recognize PIK dividend income 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 three months ended March 31, 2026 and 2025, no income was recognized related to CLO warehouse facilities. As of March 31, 2026 and December 31, 2025, 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 March 31, 2026, 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 $5.2 million. 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 three months ended March 31, 2026 and 2025, 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 March 31, 2026, the Company had one debt investment that was on non-accrual status. As of December 31, 2025, the Company did not have any debt investments 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 on debt offerings are included on the Company’s statements of assets and liabilities as a direct deduction from the related debt liability, whereas unamortized deferred debt issuance costs associated with credit facilities, if any, are included within other assets. 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, audit 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. As of March 31, 2026 and December 31, 2025, no shares were repurchased under the Share Repurchase Program.

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. In the event a redeemed CLO indenture is discharged, any remaining cost after applying any final cash payment will be recorded as a realized loss.

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, the Company 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 March 31, 2026, 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 or 2026 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 last three tax returns filed remains subject to examination by taxing authorities.

For tax purposes, the cost basis of the portfolio investments as of March 31, 2026 and December 31, 2025, was approximately $383,076,273 and $395,691,951, respectively.

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.
