Summary of Significant Accounting Policies Basis of Presentation The accompanying consolidated financial statements of the Company have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”). The accompanying consolidated financial statements of the Company and related financial information have been prepared pursuant to the requirements for reporting on Form 10-Q and Articles 6 and 10 of Regulation S-X. The Company has determined it meets the definition of an investment company and follows the accounting and reporting guidance in the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 946 – Financial Services – Investment Companies As an emerging growth company, the Company intends to take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act for complying with new or revised accounting standards.

Actual results could differ from those estimates. Consolidation As permitted under ASC Topic 946, the Company will generally not consolidate its investment in a portfolio company other than an investment company subsidiary or a controlled operating company whose business consists of providing services to the Company. Accordingly, the Company consolidated the results of its wholly-owned subsidiaries, including the SPV, SPV II, the 2022 Issuer and the Company’s wholly-owned taxable subsidiaries (the “Taxable Subsidiaries”) in its consolidated financial statements. The purpose of the Taxable Subsidiaries is to permit the Company to hold equity investments in portfolio companies that are taxed as partnerships for U.S. federal income tax purposes while complying with the “source of income” requirements contained in the RIC tax provisions of the Code. The Taxable Subsidiaries are not consolidated with the Company for U.S. federal corporate income tax purposes, and each Taxable Subsidiary is subject to U.S. federal corporate income tax on its taxable income. All intercompany balances and transactions have been eliminated. Fair Value of Financial Instruments The Company applies fair value to substantially all of its financial instruments in accordance with ASC Topic 820 — Fair Value Measurements and Disclosures ASC Topic 820 requires disclosure of the fair value of financial instruments for which it is practical to estimate such value. The Company believes that the carrying amounts of its other financial instruments such as cash, receivables and payables approximate the fair value of such items due to the short maturity of such instruments. Revenue Recognition The Company’s revenue recognition policies are as follows: Investments and related investment income: Dividend income on preferred equity securities is recorded as dividend income on an accrual basis to the extent that such amounts are payable by the portfolio company and are expected to be collected. Dividend income on common equity securities is recorded on the record date for private portfolio companies. Each distribution received from limited liability company (“LLC”) and limited partnership (“LP”) investments is evaluated to determine if the distribution should be recorded as dividend income or a return of capital. Generally, the Company will not record distributions from equity investments in LLCs and LPs as dividend income unless there are sufficient accumulated tax-basis earnings and profits in the LLC or LP prior to the applicable distribution. Distributions that are classified as a return of capital are recorded as a reduction in the cost basis of the investment. For the three months ended March 31, 2023 and 2022, the Company received return of capital distributions from its equity investments of $14 and zero, respectively. The Company has certain investments in its portfolio that contain a payment-in-kind (“PIK”) provision, which represents contractual interest or dividends that are added to the principal balance and recorded as income. The Company stops accruing PIK interest or PIK dividends when it is determined that PIK interest or PIK dividends are no longer collectible. To maintain RIC tax treatment, and to avoid incurring corporate U.S. federal income tax, substantially all income accrued from PIK provisions must be paid out to stockholders in the form of distributions, even though the Company has not yet collected the cash. Loan origination fees, original issue discount and market discount or premiums are capitalized, and the Company then amortizes such amounts using the effective interest method as interest income over the life of the investment. Unamortized discounts and loan origination fees totaled $28,812 and $29,392 as of March 31, 2023 and December 31, 2022, respectively. Upfront loan origination and closing fees received for the three months ended March 31, 2023 and 2022 totaled $1,873 and $1,031, respectively. Upon the prepayment of a loan or debt security, any unamortized premium or discount or loan origination fees are recorded as interest income. The components of the Company’s investment income were as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three months ended March 31, ​ ​ 2023 ​ 2022 Interest income ​ $ 41,457 ​ $ 13,167 PIK interest income 2,112 678 Dividend income (1) ​ 105 ​ 96 Fee income ​ 238 ​ 1,593 Prepayment gain (loss) ​ 328 ​ 210 Accretion of discounts and amortization of premiums ​ 1,612 ​ 643 Total investment income ​ $ 45,852 ​ $ 16,387 (1) During the three months ended March 31, 2023 and 2022, dividend income includes PIK dividends of $93 and $92 , respectively. ​ Investment transactions are recorded on a trade-date basis. Realized gains or losses on portfolio investments are calculated based upon the difference between the net proceeds from the disposition and the amortized cost basis of the investment, without regard to unrealized gains or losses previously recognized. Realized gains and losses are recorded within net realized gain (loss) on investments on the consolidated statements of operations. Changes in the fair value of investments from the prior period, as determined through the application of the Company’s valuation policy, are included within net change in unrealized gain (loss) on investments on the consolidated statements of operations. Non-accrual: Distributions Distributions to common stockholders are recorded on the applicable record date. The amount, if any, to be distributed to common stockholders is determined by the Board of Directors (the “Board”) at least quarterly and is generally based upon the Company’s earnings as estimated by management. Net realized capital gains, if any, are generally distributed at least annually. The determination of the tax attributes for the Company’s distributions is made annually, based upon its taxable income for the full year and distributions paid for the full year. Ordinary dividend distributions from a RIC do not qualify for the preferential tax rate on qualified dividend income from domestic corporations and qualified foreign corporations, except to the extent that the RIC received the income in the form of qualifying dividends from domestic corporations and qualified foreign corporations. The tax attributes for distributions will generally include both ordinary income and capital gains, but may also include qualified dividends or return of capital. The Company has adopted a dividend reinvestment plan (“DRIP”) that provides for the reinvestment of dividends and other distributions on behalf of its stockholders that elect to participate in such plan. When the Company declares a dividend or distribution, the Company’s stockholders’ cash distributions will only be reinvested in additional shares of the Company’s common stock if a stockholder specifically “opts in” to the DRIP at least ten Segments In accordance with ASC Topic 280 — Segment Reporting Cash The Company deposits its cash in a financial institution and, at times, such balances may be in excess of the Federal Deposit Insurance Corporation insurance limit. The Company’s deposits are held in high-quality financial institutions and management believes that risk of loss with any uninsured balance is remote. Restricted Cash Restricted cash includes amounts held within the SPV, SPV II and 2022 Issuer. Cash held within the SPV, SPV II and 2022 Issuer is generally restricted to use for the originations of new investments, the repayment of outstanding debt and the related payment of interest expense and the quarterly release of earnings to the Company. As of March 31, 2023 and December 31, 2022, restricted cash included $20,821 and $26,753, respectively, held within the SPV, $2,766 and $368, respectively, held within the SPV II and $8,656 and $19,367, respectively, held within the 2022 Issuer. Unamortized Deferred Financing Costs Deferred financing costs represent fees and other direct incremental costs incurred in connection with the Company’s borrowings. As of March 31, 2023 and December 31, 2022, the Company had unamortized deferred financing costs of $11,703 and $11,914, respectively, presented as a direct reduction of the carrying amount of debt on the consolidated statements of assets and liabilities. These amounts are amortized and included in interest and other debt financing expenses on the consolidated statements of operations over the estimated average life of the borrowings. Amortization of deferred financing costs for the three months ended March 31, 2023 and 2022 was $730 and $385, respectively. Investments Denominated in Foreign Currency At each balance sheet date, portfolio company investments denominated in foreign currencies are translated into U.S. dollars using the spot exchange rate on the last business day of the period. Purchases and sales of foreign portfolio company investments, and any income from such investments, are translated into U.S. dollars using the rates of exchange prevailing on the respective dates of such transactions. Although the fair values of foreign portfolio company investments and the fluctuation in such fair values are translated into U.S. dollars using the applicable foreign exchange rates described above, the Company does not isolate the portion of the change in fair value resulting from foreign currency exchange rates fluctuations from the change in fair value of the underlying investment. All fluctuations in fair value are included in net change in unrealized gain (loss) on investments on the Company’s consolidated statements of operations. Investments denominated in foreign currencies and foreign currency transactions may involve certain consideration and risks not typically associated with those of domestic origin, including unanticipated movements in the value of the foreign currency relative to the U.S. dollar. Derivative Instruments The Company has entered and may continue to enter into foreign currency forward contracts to reduce the Company’s exposure to foreign currency exchange rate fluctuations. In a foreign currency forward contract, the Company agrees to receive or deliver a fixed quantity of one currency for another, at a pre-determined price at a future date. Foreign currency forward contracts are marked-to-market based on the difference between the forward rate and the exchange rate at the current period end. Unrealized gain (loss) on foreign currency forward contracts are recorded on the Company’s consolidated statements of assets and liabilities by counterparty on a net basis. The Company does not utilize hedge accounting and as such values its foreign currency forward contracts at fair value with the change in unrealized gain or loss recorded in net change in unrealized gain (loss) on foreign currency forward contracts and the realized gain or loss recorded in net realized gain (loss) on foreign currency forward contracts on the Company’s consolidated statements of operations. Income Taxes The Company has elected to be treated as a RIC under Subchapter M of the Code and operates in a manner as to qualify for the tax treatment available to RICs. As long as the Company maintains its status as a RIC, it generally will not be subject to U.S. federal income taxes on any ordinary income or capital gains that it distributes at least annually to its stockholders. Rather, any tax liability related to income earned by the Company represents an obligation of the Company’s stockholders and will not be reflected in the consolidated financial statements of the Company. To qualify as a RIC under Subchapter M of the Code, the Company must, among other things, meet certain source-of-income and asset diversification requirements. In addition, to qualify for RIC tax treatment, the Company must distribute to its stockholders, for each taxable year, at least 90% of its “investment company taxable income” for that year, which is generally its ordinary income plus the excess of its realized net short-term capital gains over its realized net long-term capital losses. In order for the Company not to be subject to U.S. federal excise taxes, it must distribute annually an amount at least equal to the sum of (i) 98% of its net ordinary income (taking into account certain deferrals and elections) for the calendar year, (ii) 98.2% of its capital gains in excess of capital losses for the calendar year and (iii) any net ordinary income and capital gains in excess of capital losses for preceding years that were not distributed during such years. The Company, at its discretion, may carry forward taxable income in excess of calendar year dividends and pay U.S. federal income tax and a 4% nondeductible U.S. federal excise tax on this income. For the three months ended March 31, 2023 and 2022, the Company recorded a net expense (benefit) on the consolidated statements of operations of $195 and zero for U.S. federal excise tax, respectively. As of March 31, 2023 and December 31, 2022, the Company recorded an accrual for U.S. federal excise taxes of $150 and $125, respectively, which were included in accounts payable and accrued expenses on the consolidated statements of assets and liabilities. The Company’s consolidated Taxable Subsidiaries may be subject to U.S. federal and state corporate-level income taxes. For both the three months ended March 31, 2023 and 2022, the Company did not record a net tax expense on the consolidated statements of operations for these subsidiaries. As of both March 31, 2023 and December 31, 2022, no payables for corporate-level income taxes were accrued. The Company accounts for income taxes in conformity with ASC Topic 740 — Income Taxes Subsequent Events The Company has evaluated the need for disclosures and/or adjustments resulting from subsequent events through the date the consolidated financial statements were issued. There have been no subsequent events that occurred during such period that would require disclosure in this Form 10-Q or would be required to be recognized in the consolidated financial statements as of and for the three months ended March 31, 2023, except as disclosed in Note 13.

Fair Value Measurements

Fair Value Measurements
Fair Value Measurements	Note 4. Fair Value Measurements Investments The Company values all investments in accordance with ASC Topic 820. ASC Topic 820 requires enhanced disclosures about assets and liabilities that are measured and reported at fair value. As defined in ASC Topic 820, fair value is 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. Where available, fair value is based on observable market prices or parameters, or derived from such prices or parameters. Where observable prices or inputs are not available, valuation models are applied. These valuation models involve some level of management estimation and judgment, the degree of which is dependent on the price transparency for the assets or liabilities or market and the assets’ or liabilities’ complexity. ASC Topic 820 establishes a hierarchal disclosure framework which prioritizes and ranks the level of market price observability of inputs used in measuring investments at fair value. Market price observability is affected by a number of factors, including the type of investment and the characteristics specific to the investment. Investments with readily available active quoted prices or for which fair value can be measured from actively quoted prices generally will have a higher degree of market price observability and a lesser degree of judgment used in measuring fair value. Based on the observability of the inputs used in the valuation techniques, the Company is required to provide disclosures on fair value measurements according to the fair value hierarchy. The fair value hierarchy ranks the observability of the inputs used to determine fair values. Investments carried at fair value are classified and disclosed in one of the following three categories: ● Level 1 – Valuations based on unadjusted quoted prices in active markets for identical assets or liabilities at the measurement date. ● Level 2 – Valuations based on inputs other than quoted prices in active markets, including quoted prices for similar assets or liabilities, which are either directly or indirectly observable. ● Level 3 – Valuations based on inputs that are unobservable and significant to the overall fair value measurement. This includes situations where there is little, if any, market activity for the assets or liabilities. The inputs into the determination of fair value are based upon the best information available and may require significant management judgment or estimation. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, an asset’s or liability’s categorization within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the asset or liability. For periods prior to September 30, 2022, the Board determined the fair value of the Company’s investments. Pursuant to the new SEC Rule 2a-5 of the 1940 Act, on September 30, 2022 the Board designated MC Advisors as the Company’s valuation designee (the “Valuation Designee”). The Board is responsible for oversight of the Valuation Designee. The Valuation Designee has established a valuation committee to determine in good faith the fair value of the Company’s investments, based on input of Valuation Designee’s management and personnel and independent valuation firms which are engaged at the direction of the valuation committee to assist in the valuation of certain portfolio investments lacking a readily available market quotation. The valuation committee determines fair values pursuant to a valuation policy approved by the Board and pursuant to a consistently applied valuation process. With respect to investments for which market quotations are not readily available, the Valuation Designee undertakes a multi-step valuation process each quarter, as described below: ● the quarterly valuation process begins with each portfolio company or investment being initially evaluated and rated by the investment professionals of the Valuation Designee responsible for the credit monitoring of the portfolio investment; ● the Valuation Designee engages an independent valuation firm to conduct independent appraisals of a selection of investments for which market quotations are not readily available. The Valuation Designee will consult with an independent valuation firm relative to each portfolio company at least once in every calendar year, but the independent appraisals are generally received quarterly for each investment; ● to the extent an independent valuation firm is not engaged to conduct an investment appraisal on an investment for which market quotations are not readily available, the investment will be valued by the Valuation Designee; ● preliminary valuation conclusions are then documented and discussed with the valuation committee of the Valuation Designee; ● the valuation conclusions are approved by the valuation committee of the Valuation Designee; and ● a report prepared by the Valuation Designee is presented to the Board quarterly to allow the Board to perform its oversight duties of the valuation process and the Valuation Designee. The accompanying consolidated schedules of investments held by the Company consist primarily of private debt instruments (“Level 3 debt”). The Valuation Designee generally uses the income approach to determine fair value for Level 3 debt where market quotations are not readily available, as long as it is appropriate. If there is deterioration in credit quality or a debt investment is in workout status, the Valuation Designee may consider other factors in determining the fair value, including the value attributable to the debt investment from the enterprise value of the portfolio company or the proceeds that would be received in a liquidation analysis. This liquidation analysis may include probability weighting of alternative outcomes. The Valuation Designee generally considers the Company’s Level 3 debt to be performing if the borrower is not in default, the borrower is remitting payments in a timely manner; the loan is in covenant compliance or is otherwise not deemed to be impaired. In determining the fair value of the performing Level 3 debt, the Valuation Designee considers fluctuations in current interest rates, the trends in yields of debt instruments with similar credit ratings, financial condition of the borrower, economic conditions and other relevant factors, both qualitative and quantitative. In the event that a Level 3 debt instrument is not performing, as defined above, the Valuation Designee will evaluate the value of the collateral utilizing the same framework described above for a performing loan to determine the value of the Level 3 debt instrument. Under the income approach, discounted cash flow models are utilized to determine the present value of the future cash flow streams of its debt investments, based on future interest and principal payments as set forth in the associated loan agreements. In determining fair value under the income approach, the Valuation Designee also considers the following factors: applicable market yields and leverage levels, credit quality, prepayment penalties, the nature and realizable value of any collateral, the portfolio company’s ability to make payments, and changes in the interest rate environment and the credit markets that generally may affect the price at which similar investments may be made. Under the market approach, the enterprise value methodology is typically utilized to determine the fair value of an investment. There is no one methodology to estimate enterprise value and, in fact, for any one portfolio company, enterprise value is generally best expressed as a range of values, from which the Valuation Designee derives a single estimate of enterprise value. In estimating the enterprise value of a portfolio company, the Valuation Designee analyzes various factors consistent with industry practice, including but not limited to original transaction multiples, the portfolio company’s historical and projected financial results, applicable market trading and transaction comparables, applicable market yields and leverage levels, the nature and realizable value of any collateral, the markets in which the portfolio company does business, and comparisons of financial ratios of peer companies that are public. Typically, the enterprise values of private companies are based on multiples of earnings before interest, income taxes, depreciation and amortization (“EBITDA”), cash flows, net income, revenues, or in limited cases, book value. In addition, for certain debt investments, the Valuation Designee may base its valuation on indicative bid and ask prices provided by an independent third-party pricing service. Bid prices reflect the highest price that the Company and others may be willing to pay. Ask prices represent the lowest price that the Company and others may be willing to accept. The Valuation Designee generally uses the midpoint of the bid/ask range as its best estimate of fair value of such investment. As of March 31, 2023, the Valuation Designee determined, in good faith, the fair value of the Company’s portfolio investments in accordance with GAAP and the Company’s valuation procedures based on the facts and circumstances known by the Company at that time, or reasonably expected to be known at that time. Foreign Currency Forward Contracts The valuation for the Company’s foreign currency forward contracts is based on the difference between the exchange rate associated with the forward contract and the exchange rate at the current period end. Foreign currency forward contracts are categorized as Level 2 in the fair value hierarchy. Fair Value Disclosures The following tables present fair value measurements of investments and foreign currency forward contracts, by major class according to the fair value hierarchy: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Fair Value Measurements March 31, 2023 Level 1 Level 2 Level 3 Total Senior secured loans ​ $ — ​ $ — ​ $ 1,320,148 ​ $ 1,320,148 Unitranche secured loans ​ — ​ — ​ 128,380 ​ 128,380 Junior secured loans ​ — ​ — ​ 44,633 ​ 44,633 Equity securities ​ 52 ​ — ​ 50,697 ​ 50,749 Total investments ​ $ 52 ​ $ — ​ $ 1,543,858 ​ $ 1,543,910 Foreign currency forward contracts asset (liability) ​ $ — ​ $ 1,409 ​ $ — ​ $ 1,409 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Fair Value Measurements December 31, 2022 Level 1 Level 2 Level 3 Total Senior secured loans ​ $ — ​ $ — ​ $ 1,250,788 ​ $ 1,250,788 Unitranche secured loans ​ — ​ — ​ 127,378 ​ 127,378 Junior secured loans ​ — ​ — ​ 44,469 ​ 44,469 Equity securities ​ 34 ​ — ​ 46,327 ​ 46,361 Total investments ​ $ 34 ​ $ — ​ $ 1,468,962 ​ $ 1,468,996 Foreign currency forward contracts asset (liability) ​ $ — ​ $ 1,296 ​ $ — ​ $ 1,296 ​ Senior secured loans, unitranche secured loans and junior secured loans are collateralized by tangible and intangible assets of the borrowers. These investments include loans to entities that have some level of challenge in obtaining financing from other, more conventional institutions, such as a bank. Interest rates on these loans are either fixed or floating and are based on current market conditions and credit ratings of the borrower. Excluding loans on non-accrual, the contractual interest rates on the loans ranged from 8.00% to 20.66% at March 31, 2023 and 7.14% to 19.50% at December 31, 2022. The maturity dates on the loans outstanding at March 31, 2023 range between May 2023 and April 2030.

The total net change in unrealized gain (loss) on investments included on the consolidated statements of operations for the three months ended March 31, 2023 and 2022, attributable to Level 3 investments still held at March 31, 2023 and 2022, was $5,633 and $3,164, respectively. Reclassifications impacting Level 3 of the fair value hierarchy are reported as transfers in or out of Level 3 as of the beginning of the period in which the reclassifications occur. There were no transfers among Levels 1, 2 and 3 during the three months ended March 31, 2023 and 2022. Significant Unobservable Inputs ASC Topic 820 requires disclosure of quantitative information about the significant unobservable inputs used in the valuation of assets and liabilities classified as Level 3 within the fair value hierarchy. Disclosure of this information is not required in circumstances where a valuation (unadjusted) is obtained from a third-party pricing service and the information regarding the unobservable inputs is not reasonably available to the Company and as such, the disclosures provided below exclude those investments valued in that manner. The tables below are not intended to be all-inclusive, but rather to provide information on significant unobservable inputs and valuation techniques used by the Valuation Designee. The valuation techniques and significant unobservable inputs used in recurring Level 3 fair value measurements of assets as of March 31, 2023 were as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Weighted ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Unobservable ​ Average ​ Range ​ Fair Value Valuation Technique Input Mean Minimum Maximum Assets: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Senior secured loans ​ $ 817,101 Discounted cash flow EBITDA multiples 11.1 x 4.0 x 19.5 x ​ ​ ​ ​ ​ Market yields ​ 11.0 % 8.3 % 20.8 % Senior secured loans ​ 380,294 Discounted cash flow Revenue multiples 7.3 x 1.4 x 20.0 x ​ ​ ​ ​ ​ Market yields ​ 11.4 % 9.5 % 16.6 % Senior secured loans ​ 2,376 Enterprise value Revenue multiples 0.8 x 0.8 x 0.8 x Unitranche secured loans ​ 95,974 Discounted cash flow EBITDA multiples 9.7 x 8.3 x 14.5 x ​ ​ ​ ​ Market yields 14.5 % 8.7 % 25.1 % Unitranche secured loans ​ 32,406 Discounted cash flow ​ Revenue multiples ​ 9.4 x 6.0 x 12.5 x ​ ​ ​ ​ Market yields 11.4 % 11.2 % 11.7 % Junior secured loans ​ 44,633 Discounted cash flow Market yields 13.0 % 12.4 % 15.6 % Equity securities ​ 35,515 Enterprise value EBITDA multiples 11.8 x 4.0 x 18.6 x Equity securities ​ 13,172 Enterprise value Revenue multiples 5.2 x 1.4 x 11.3 x Equity securities ​ 1,402 Option pricing model Volatility 62.9 % 45.0 % 74.0 % Total Level 3 Assets ​ $ 1,422,873 (1) ​ ​ ​ ​ ​ ​ (1) Excludes investments of $120,985 at fair value where valuation (unadjusted) is obtained from a third-party pricing service for which such disclosure is not required.

The significant unobservable input used in the income approach of fair value measurement of the Company’s investments is the discount rate used to discount the estimated future cash flows expected to be received from the underlying investment, which include both future principal and interest payments. Increases (decreases) in the discount rate would result in a decrease (increase) in the fair value estimate of the investment. Included in the consideration and selection of discount rates are the following factors: risk of default, rating of the investment and comparable investments, and call provisions. The significant unobservable inputs used in the market approach of fair value measurement of the Company’s investments are the market multiples of EBITDA or revenue of the comparable guideline public companies. The Valuation Designee selects a population of public companies for each investment with similar operations and attributes of the portfolio company. Using these guideline public companies’ data, a range of multiples of enterprise value to EBITDA or revenue is calculated. The Valuation Designee selects percentages from the range of multiples for purposes of determining the portfolio company’s estimated enterprise value based on said multiple and generally the latest twelve months EBITDA or revenue of the portfolio company (or other meaningful measure). Increases (decreases) in the multiple will result in an increase (decrease) in enterprise value, resulting in an increase (decrease) in the fair value estimate of the investment. Other Financial Assets and Liabilities ASC Topic 820 requires disclosure of the fair value of financial instruments for which it is practical to estimate such value. The Company believes that the carrying amounts of its other financial instruments such as cash, receivables and payables approximate the fair value of such items due to the short maturity of such instruments. Fair value of the Company’s Credit Facility, Term Loan and 2022 ABS is estimated by discounting remaining payments using applicable market rates or market quotes for similar instruments at the measurement date, if applicable. As of both March 31, 2023 and December 31, 2022, the Company believes that the carrying value of its Credit Facility approximates fair value. As of both March 31, 2023 and December 31, 2022, the Company believes that the carrying value of its Term Loan approximates fair value. As of March 31, 2023 and December 31, 2022, the estimated fair value of the Company’s 2022 ABS Class A and Class B notes was $301,552 and $300,028, respectively.

Transactions with Related Parties
Transactions with Related Parties	Note 6. Transactions with Related Parties The Company has entered into an investment advisory agreement with MC Advisors (the “Investment Advisory Agreement”), under which MC Advisors, subject to the overall supervision of the Board, provides investment advisory services to the Company. The Company pays MC Advisors a fee for its services under the Investment Advisory Agreement consisting of two components - a base management fee and an incentive fee. The cost of both the base management fee and the incentive fee are borne by the Company’s stockholders, unless such fees are waived by MC Advisors. On April 18, 2022, MC Advisors agreed to permanently waive a portion of the base management fees and incentive fees payable by the Company to MC Advisors under the Investment Advisory Agreement pursuant to a fee waiver letter. The base management fee waiver took effect beginning April 1, 2022 (the “Effective Date”) and the incentive fee waivers took effect beginning January 1, 2022. Beginning with the Effective Date, the base management fee is calculated at an annual rate of 1.25% of average total assets (reduced from 1.50%), which includes assets financed using leverage. Following any future quotation or listing of the Company’s securities on a national securities exchange (an “Exchange Listing”) or any future quotation or listing of its securities on any other public trading market, the base management fee will be calculated at an annual rate of 1.75% of average invested assets (calculated as total assets excluding cash). The base management fee is payable in arrears. Base management fees for the three months ended March 31, 2023 and 2022 were $4,847 and $2,796, respectively. There were no base management fee waivers for both the three months ended March 31, 2023 and 2022. The incentive fee consists of two parts. The first part is calculated and payable quarterly in arrears based on the Company’s pre-incentive fee net investment income for the preceding quarter. 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 but excluding fees for providing managerial assistance) accrued during the calendar quarter, minus operating expenses for the quarter (including the base management fee), any expenses payable under the administration agreement (the “Administration Agreement”) between the Company and Monroe Capital Management Advisors, LLC (“MC Management”) and any interest expense and dividends paid on any outstanding preferred stock, but excluding the incentive fee. Pre-incentive fee net investment income will include, in the case of investments with a deferred interest feature such as market discount, debt instruments with PIK interest, preferred stock with PIK dividends and zero-coupon securities, accrued income that the Company has not yet received in cash. MC Advisors is not under any obligation to reimburse the Company for any part of the incentive fee it receives that was based on accrued interest that the Company never actually receives. Pre-incentive fee net investment income does not include any realized capital gains or losses or unrealized capital gains or losses. If any distributions from portfolio companies are characterized as a return of capital, such returns of capital would affect the capital gains incentive fee to the extent a gain or loss is realized. Because of the structure of the incentive fee, it is possible that the Company may pay an incentive fee in a quarter where it incurs a loss. For example, if the Company receives pre-incentive fee net investment income in excess of the hurdle rate (as defined below) for a quarter, the Company will pay the applicable incentive fee even if it has incurred a loss in that quarter due to realized and unrealized capital losses. Pre-incentive fee net investment income, expressed as a rate of return on the value of the Company’s net assets (defined as total assets less indebtedness and before taking into account any incentive fees payable during the period) at the end of the immediately preceding calendar quarter, is compared to a fixed “hurdle rate” of 1.50% per quarter (6% annually). As of and beginning with the Effective Date, prior to an Exchange Listing, the Company shall pay MC Advisors an incentive fee with respect to its pre-incentive fee net investment income in each calendar quarter as follows: ● no incentive fee in any calendar quarter in which the pre-incentive fee net investment income does not exceed the hurdle rate of 1.50% ( 6% annually); ● 100% of the Company’s pre-incentive fee net investment income with respect to that portion of such pre-incentive fee net investment income, if any, that exceeds the hurdle rate but is less than 1.7143% (reduced from 1.76% pursuant to the fee waiver letter effective April 1, 2022) in any calendar quarter prior to an Exchange Listing or 1.88% in any calendar quarter following an Exchange Listing. This portion of the Company’s pre-incentive fee net investment income is referred to as the “catch-up” provision; and ● prior to an Exchange Listing, 12.5% of the amount of the Company’s pre-incentive fee net investment income (a reduction from 15.0% of the amount of the Company’s pre-incentive fee net income), if any, that exceeds 1.7143% (reduced from 1.76% pursuant to the fee waiver letter effective April 1, 2022) in any calendar quarter, and following an Exchange Listing, 20% of the amount of the Company’s pre-incentive fee net investment income, if any, that exceeds 1.88% in any calendar quarter. These calculations are appropriately prorated for any period of less than three months and adjusted for any share issuances or repurchases during the current quarter. The second part of the incentive fee is a capital gains incentive fee that is determined and payable in arrears as of the end of each fiscal year (or upon termination of the Investment Advisory Agreement, as of the termination date), and equals 12.5% (reduced from 15.0% effective January 1, 2022 pursuant to the fee waiver letter) of the Company’s realized capital gains as of the end of the fiscal year. In determining the capital gains incentive fee payable to MC Advisors, the Company calculates the cumulative aggregate realized capital gains and cumulative aggregate realized capital losses since the Company’s inception, and the aggregate unrealized capital depreciation as of the date of the calculation, as applicable, with respect to each of the investments in the Company’s portfolio. For this purpose, cumulative aggregate realized capital gains, if any, equals the sum of the differences between the net sales price of each investment, when sold, and the amortized cost of such investment. Cumulative aggregate realized capital losses equals the sum of the amounts by which the net sales price of each investment, when sold, is less than the amortized cost of such investment since the Company’s inception. Aggregate unrealized capital depreciation equals the sum of the difference, if negative, between the valuation of each investment as of the applicable calculation date and the amortized cost of such investment. At the end of the applicable year, the amount of capital gains that will serve as the basis for the calculation of the capital gains incentive fee equals the cumulative aggregate realized capital gains less cumulative aggregate realized capital losses, less aggregate unrealized capital depreciation, with respect to the Company’s portfolio of investments. If this number is positive at the end of such year, then the capital gains incentive fee for such year equals 12.5% of such amount, less the aggregate amount of any capital gains incentive fees paid in respect of the Company’s portfolio in all prior years. While the Investment Advisory Agreement with MC Advisors neither includes nor contemplates the inclusion of unrealized gains in the calculation of the capital gains incentive fee, pursuant to an interpretation of an American Institute for Certified Public Accountants Technical Practice Aid for investment companies, the Company includes unrealized gains in the calculation of the capital gains incentive fee expense and related accrued capital gains incentive fee. This accrual reflects the incentive fees that would be payable to MC Advisors if the Company’s entire portfolio was liquidated at its fair value as of the balance sheet date even though MC Advisors is not entitled to an incentive fee with respect to unrealized gains unless and until such gains are actually realized. The composition of the Company’s incentive fees was as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ Three months ended March 31, ​ ​ 2023 2022 Part one incentive fees (1) ​ $ 3,439 ​ $ 1,461 Part two incentive fees (2) ​ 712 ​ 362 Total incentive fees (3) ​ $ 4,151 ​ $ 1,823 (1) Based on pre-incentive fee net investment income. (2) Based upon net realized and unrealized gains and losses, or capital gains. The Company accrues, but does not pay, a capital gains incentive fee in connection with any unrealized capital appreciation, as appropriate. If, on a cumulative basis, the sum of net realized gain (loss) plus net unrealized gain (loss) decreases during a period, the Company will reverse any excess capital gains incentive fee previously accrued such that the amount of capital gains incentive fee accrued is no more than 12.5% of the sum of net realized gain (loss) plus net unrealized gain (loss). (3) There were no incentive fee waivers during the periods presented.

Share Repurchase Program During 2022, the Company commenced a quarterly share repurchase program in which the Company intends to repurchase, in each quarter, up to 5% of the shares of common stock outstanding as of the close of the previous calendar quarter (the “Share Repurchase Program”), subject to the discretion of the Board. Any such repurchases are subject to approval by the Board, in its discretion, and the availability of cash to fund such repurchases. The Board may amend, suspend or terminate the share repurchase program if it deems such action to be in the Company’s best interest and the best interest of the Company’s stockholders. As a result, share repurchases may not be available each quarter. The Company intends to conduct such repurchase offers in accordance with the requirements of Rule 13e-4 under the Securities Exchange Act of 1934 and the 1940 Act and subject to compliance with applicable covenants and restrictions under the Company’s financing arrangements. All shares repurchased by the Company pursuant to the terms of each tender offer will be redeemed and thereafter will be authorized and unissued shares.

(2) The per share data for distributions reflects the actual amount of distributions declared during the period. Management monitors available taxable earnings, including net investment income and realized capital gains, to determine if a tax return of capital may occur for the year. To the extent the Company’s taxable earnings fall below the total amount of the Company’s distributions for that fiscal year, a portion of those distributions may be deemed a tax return of capital to the Company’s stockholders. The tax character of distributions will be determined at the end of the fiscal year. However, if the character of such distributions were determined as of March 31, 2023 and 2022, none of the distributions would have been characterized as a tax return of capital to the Company’s stockholders; this tax return of capital may differ from the return of capital calculated with reference to net investment income for financial reporting purposes. (3) Includes the impact of different share amounts used in calculating per share data as a result of calculating certain per share data based on weighted average shares outstanding during the period and certain per share data based on shares outstanding as of a period end or transaction date. (4) Total return based on average net asset value is calculated by dividing the net increase (decrease) in net assets resulting from operations by the average net asset value. Return calculations are not annualized. (5) Ratio is not annualized. (6) Ratios are annualized. To the extent incentive fees are included within the ratio, they are not annualized.

Summary of Significant Accounting Policies
Basis of Presentation	Basis of Presentation The accompanying consolidated financial statements of the Company have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”). The accompanying consolidated financial statements of the Company and related financial information have been prepared pursuant to the requirements for reporting on Form 10-Q and Articles 6 and 10 of Regulation S-X. The Company has determined it meets the definition of an investment company and follows the accounting and reporting guidance in the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 946 – Financial Services – Investment Companies As an emerging growth company, the Company intends to take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act for complying with new or revised accounting standards.
Use of Estimates	Use of Estimates The preparation of the consolidated financial statements in conformity with GAAP requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.
Consolidation	Consolidation As permitted under ASC Topic 946, the Company will generally not consolidate its investment in a portfolio company other than an investment company subsidiary or a controlled operating company whose business consists of providing services to the Company. Accordingly, the Company consolidated the results of its wholly-owned subsidiaries, including the SPV, SPV II, the 2022 Issuer and the Company’s wholly-owned taxable subsidiaries (the “Taxable Subsidiaries”) in its consolidated financial statements. The purpose of the Taxable Subsidiaries is to permit the Company to hold equity investments in portfolio companies that are taxed as partnerships for U.S. federal income tax purposes while complying with the “source of income” requirements contained in the RIC tax provisions of the Code. The Taxable Subsidiaries are not consolidated with the Company for U.S. federal corporate income tax purposes, and each Taxable Subsidiary is subject to U.S. federal corporate income tax on its taxable income. All intercompany balances and transactions have been eliminated.
Fair Value of Financial Instruments	Fair Value of Financial Instruments The Company applies fair value to substantially all of its financial instruments in accordance with ASC Topic 820 — Fair Value Measurements and Disclosures ASC Topic 820 requires disclosure of the fair value of financial instruments for which it is practical to estimate such value. The Company believes that the carrying amounts of its other financial instruments such as cash, receivables and payables approximate the fair value of such items due to the short maturity of such instruments.
Revenue Recognition	Revenue Recognition The Company’s revenue recognition policies are as follows: Investments and related investment income: Dividend income on preferred equity securities is recorded as dividend income on an accrual basis to the extent that such amounts are payable by the portfolio company and are expected to be collected. Dividend income on common equity securities is recorded on the record date for private portfolio companies. Each distribution received from limited liability company (“LLC”) and limited partnership (“LP”) investments is evaluated to determine if the distribution should be recorded as dividend income or a return of capital. Generally, the Company will not record distributions from equity investments in LLCs and LPs as dividend income unless there are sufficient accumulated tax-basis earnings and profits in the LLC or LP prior to the applicable distribution. Distributions that are classified as a return of capital are recorded as a reduction in the cost basis of the investment. For the three months ended March 31, 2023 and 2022, the Company received return of capital distributions from its equity investments of $14 and zero, respectively. The Company has certain investments in its portfolio that contain a payment-in-kind (“PIK”) provision, which represents contractual interest or dividends that are added to the principal balance and recorded as income. The Company stops accruing PIK interest or PIK dividends when it is determined that PIK interest or PIK dividends are no longer collectible. To maintain RIC tax treatment, and to avoid incurring corporate U.S. federal income tax, substantially all income accrued from PIK provisions must be paid out to stockholders in the form of distributions, even though the Company has not yet collected the cash. Loan origination fees, original issue discount and market discount or premiums are capitalized, and the Company then amortizes such amounts using the effective interest method as interest income over the life of the investment. Unamortized discounts and loan origination fees totaled $28,812 and $29,392 as of March 31, 2023 and December 31, 2022, respectively. Upfront loan origination and closing fees received for the three months ended March 31, 2023 and 2022 totaled $1,873 and $1,031, respectively. Upon the prepayment of a loan or debt security, any unamortized premium or discount or loan origination fees are recorded as interest income. The components of the Company’s investment income were as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three months ended March 31, ​ ​ 2023 ​ 2022 Interest income ​ $ 41,457 ​ $ 13,167 PIK interest income 2,112 678 Dividend income (1) ​ 105 ​ 96 Fee income ​ 238 ​ 1,593 Prepayment gain (loss) ​ 328 ​ 210 Accretion of discounts and amortization of premiums ​ 1,612 ​ 643 Total investment income ​ $ 45,852 ​ $ 16,387 (1) During the three months ended March 31, 2023 and 2022, dividend income includes PIK dividends of $93 and $92 , respectively. ​ Investment transactions are recorded on a trade-date basis. Realized gains or losses on portfolio investments are calculated based upon the difference between the net proceeds from the disposition and the amortized cost basis of the investment, without regard to unrealized gains or losses previously recognized. Realized gains and losses are recorded within net realized gain (loss) on investments on the consolidated statements of operations. Changes in the fair value of investments from the prior period, as determined through the application of the Company’s valuation policy, are included within net change in unrealized gain (loss) on investments on the consolidated statements of operations. Non-accrual:
Distributions	Distributions Distributions to common stockholders are recorded on the applicable record date. The amount, if any, to be distributed to common stockholders is determined by the Board of Directors (the “Board”) at least quarterly and is generally based upon the Company’s earnings as estimated by management. Net realized capital gains, if any, are generally distributed at least annually. The determination of the tax attributes for the Company’s distributions is made annually, based upon its taxable income for the full year and distributions paid for the full year. Ordinary dividend distributions from a RIC do not qualify for the preferential tax rate on qualified dividend income from domestic corporations and qualified foreign corporations, except to the extent that the RIC received the income in the form of qualifying dividends from domestic corporations and qualified foreign corporations. The tax attributes for distributions will generally include both ordinary income and capital gains, but may also include qualified dividends or return of capital. The Company has adopted a dividend reinvestment plan (“DRIP”) that provides for the reinvestment of dividends and other distributions on behalf of its stockholders that elect to participate in such plan. When the Company declares a dividend or distribution, the Company’s stockholders’ cash distributions will only be reinvested in additional shares of the Company’s common stock if a stockholder specifically “opts in” to the DRIP at least ten
Segments	Segments In accordance with ASC Topic 280 — Segment Reporting
Cash	Cash The Company deposits its cash in a financial institution and, at times, such balances may be in excess of the Federal Deposit Insurance Corporation insurance limit. The Company’s deposits are held in high-quality financial institutions and management believes that risk of loss with any uninsured balance is remote.
Restricted Cash	Restricted Cash Restricted cash includes amounts held within the SPV, SPV II and 2022 Issuer. Cash held within the SPV, SPV II and 2022 Issuer is generally restricted to use for the originations of new investments, the repayment of outstanding debt and the related payment of interest expense and the quarterly release of earnings to the Company. As of March 31, 2023 and December 31, 2022, restricted cash included $20,821 and $26,753, respectively, held within the SPV, $2,766 and $368, respectively, held within the SPV II and $8,656 and $19,367, respectively, held within the 2022 Issuer.
Unamortized Deferred Financing Costs	Unamortized Deferred Financing Costs Deferred financing costs represent fees and other direct incremental costs incurred in connection with the Company’s borrowings. As of March 31, 2023 and December 31, 2022, the Company had unamortized deferred financing costs of $11,703 and $11,914, respectively, presented as a direct reduction of the carrying amount of debt on the consolidated statements of assets and liabilities. These amounts are amortized and included in interest and other debt financing expenses on the consolidated statements of operations over the estimated average life of the borrowings. Amortization of deferred financing costs for the three months ended March 31, 2023 and 2022 was $730 and $385, respectively.
Investments Denominated in Foreign Currency	Investments Denominated in Foreign Currency At each balance sheet date, portfolio company investments denominated in foreign currencies are translated into U.S. dollars using the spot exchange rate on the last business day of the period. Purchases and sales of foreign portfolio company investments, and any income from such investments, are translated into U.S. dollars using the rates of exchange prevailing on the respective dates of such transactions. Although the fair values of foreign portfolio company investments and the fluctuation in such fair values are translated into U.S. dollars using the applicable foreign exchange rates described above, the Company does not isolate the portion of the change in fair value resulting from foreign currency exchange rates fluctuations from the change in fair value of the underlying investment. All fluctuations in fair value are included in net change in unrealized gain (loss) on investments on the Company’s consolidated statements of operations. Investments denominated in foreign currencies and foreign currency transactions may involve certain consideration and risks not typically associated with those of domestic origin, including unanticipated movements in the value of the foreign currency relative to the U.S. dollar.
Derivative Instruments	Derivative Instruments The Company has entered and may continue to enter into foreign currency forward contracts to reduce the Company’s exposure to foreign currency exchange rate fluctuations. In a foreign currency forward contract, the Company agrees to receive or deliver a fixed quantity of one currency for another, at a pre-determined price at a future date. Foreign currency forward contracts are marked-to-market based on the difference between the forward rate and the exchange rate at the current period end. Unrealized gain (loss) on foreign currency forward contracts are recorded on the Company’s consolidated statements of assets and liabilities by counterparty on a net basis. The Company does not utilize hedge accounting and as such values its foreign currency forward contracts at fair value with the change in unrealized gain or loss recorded in net change in unrealized gain (loss) on foreign currency forward contracts and the realized gain or loss recorded in net realized gain (loss) on foreign currency forward contracts on the Company’s consolidated statements of operations.
Income Taxes	Income Taxes The Company has elected to be treated as a RIC under Subchapter M of the Code and operates in a manner as to qualify for the tax treatment available to RICs. As long as the Company maintains its status as a RIC, it generally will not be subject to U.S. federal income taxes on any ordinary income or capital gains that it distributes at least annually to its stockholders. Rather, any tax liability related to income earned by the Company represents an obligation of the Company’s stockholders and will not be reflected in the consolidated financial statements of the Company. To qualify as a RIC under Subchapter M of the Code, the Company must, among other things, meet certain source-of-income and asset diversification requirements. In addition, to qualify for RIC tax treatment, the Company must distribute to its stockholders, for each taxable year, at least 90% of its “investment company taxable income” for that year, which is generally its ordinary income plus the excess of its realized net short-term capital gains over its realized net long-term capital losses. In order for the Company not to be subject to U.S. federal excise taxes, it must distribute annually an amount at least equal to the sum of (i) 98% of its net ordinary income (taking into account certain deferrals and elections) for the calendar year, (ii) 98.2% of its capital gains in excess of capital losses for the calendar year and (iii) any net ordinary income and capital gains in excess of capital losses for preceding years that were not distributed during such years. The Company, at its discretion, may carry forward taxable income in excess of calendar year dividends and pay U.S. federal income tax and a 4% nondeductible U.S. federal excise tax on this income. For the three months ended March 31, 2023 and 2022, the Company recorded a net expense (benefit) on the consolidated statements of operations of $195 and zero for U.S. federal excise tax, respectively. As of March 31, 2023 and December 31, 2022, the Company recorded an accrual for U.S. federal excise taxes of $150 and $125, respectively, which were included in accounts payable and accrued expenses on the consolidated statements of assets and liabilities. The Company’s consolidated Taxable Subsidiaries may be subject to U.S. federal and state corporate-level income taxes. For both the three months ended March 31, 2023 and 2022, the Company did not record a net tax expense on the consolidated statements of operations for these subsidiaries. As of both March 31, 2023 and December 31, 2022, no payables for corporate-level income taxes were accrued. The Company accounts for income taxes in conformity with ASC Topic 740 — Income Taxes
Subsequent Events	Subsequent Events The Company has evaluated the need for disclosures and/or adjustments resulting from subsequent events through the date the consolidated financial statements were issued. There have been no subsequent events that occurred during such period that would require disclosure in this Form 10-Q or would be required to be recognized in the consolidated financial statements as of and for the three months ended March 31, 2023, except as disclosed in Note 13.

(2) The per share data for distributions reflects the actual amount of distributions declared during the period. Management monitors available taxable earnings, including net investment income and realized capital gains, to determine if a tax return of capital may occur for the year. To the extent the Company’s taxable earnings fall below the total amount of the Company’s distributions for that fiscal year, a portion of those distributions may be deemed a tax return of capital to the Company’s stockholders. The tax character of distributions will be determined at the end of the fiscal year. However, if the character of such distributions were determined as of March 31, 2023 and 2022, none of the distributions would have been characterized as a tax return of capital to the Company’s stockholders; this tax return of capital may differ from the return of capital calculated with reference to net investment income for financial reporting purposes. (3) Includes the impact of different share amounts used in calculating per share data as a result of calculating certain per share data based on weighted average shares outstanding during the period and certain per share data based on shares outstanding as of a period end or transaction date. (4) Total return based on average net asset value is calculated by dividing the net increase (decrease) in net assets resulting from operations by the average net asset value. Return calculations are not annualized. (5) Ratio is not annualized. (6) Ratios are annualized. To the extent incentive fees are included within the ratio, they are not annualized.
