Hercules Capital, Inc.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Description of Business

Hercules Capital, Inc. (the “Company”) is a specialty finance company focused on providing senior secured loans to high-growth, innovative venture capital-backed and institutional-backed companies in a variety of technology and life sciences industries. The Company sources its investments through its principal office located in San Mateo, CA, as well as through its additional offices in Boston, MA, New York, NY, San Diego, CA, Denver, CO, and London, United Kingdom. The Company was incorporated under the General Corporation Law of the State of Maryland in December 2003.

The Company is an internally managed, non-diversified closed-end investment company that has elected to be regulated as a business development company (“BDC”) under the Investment Company Act of 1940, as amended (the “1940 Act”). Effective January 1, 2006, the Company elected to be treated for U.S. federal income tax purposes as a regulated investment company (“RIC”) under Subchapter M Part I of the Internal Revenue Code of 1986, as amended (the “Code”) (see “Note 6 - Income Taxes”).

The Company is not registered with the Commodity Futures Trading Commission (“CFTC”). The Company has claimed an exclusion from the definition of the term “commodity pool operator” under the Commodity Exchange Act (“CEA”), pursuant to Rule 4.5 under the CEA. Therefore, the Company is not, subject to registration or regulation as a “commodity pool operator” under the CEA.

Hercules Capital IV, L.P. (“HC IV”) and Hercules SBIC V, L.P. (“SBIC V”) are our wholly owned Delaware limited partnerships that were formed in December 2010 and September 2023, respectively. HC IV and SBIC V have each received licenses to operate as a Small Business Investment Company (“SBIC”) under the authority of the Small Business Administration (“SBA”) on October 27, 2020 and July 9, 2024, respectively. Our SBICs are subject to a variety of regulations concerning, among other things, the size and nature of the companies in which they may invest and the structure of those investments. Hercules Technology SBIC Management, LLC (“HTM”), is a wholly owned limited liability company subsidiary of the Company, which was formed in November 2003 and serves as the general partner of HC IV and SBIC V.

The Company has also established certain wholly owned subsidiaries, all of which are structured as Delaware corporations or limited liability companies (“LLCs”), to hold portfolio companies organized as LLCs (or other forms of pass-through entities). These subsidiaries are consolidated for financial reporting purposes in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”). Certain of the subsidiaries are taxable and not consolidated with Hercules for income tax purposes and may generate income tax expense, or benefit, and tax assets and liabilities as a result of their ownership of certain portfolio investments.

The Company formed Hercules Capital Management LLC and Hercules Adviser LLC in 2020 as wholly owned Delaware limited liability subsidiaries. The Company was granted no-action relief by the staff of the Securities and Exchange Commission (“SEC”) to allow Hercules Adviser LLC (the “Adviser Subsidiary”) to register as a registered investment adviser under the Investment Advisers Act of 1940, as amended (“Advisers Act”). The Adviser Subsidiary provides investment advisory and related services to investment vehicles (“Adviser Funds”) owned by one or more unrelated third-party investors (“External Parties”). The Adviser Subsidiary is owned by Hercules Capital Management LLC and collectively held and presented with Hercules Partner Holdings, LLC, which separately wholly owns the general partnership interests to each of the Adviser Funds.

2. Summary of Significant Accounting Policies

Basis of Presentation

The accompanying consolidated interim financial statements have been prepared in accordance with U.S. GAAP for interim financial information, and pursuant to the requirements for reporting on Form 10-Q and Articles 6, 10 and 12 of Regulation S-X. Accordingly, certain disclosures accompanying annual consolidated financial statements prepared in accordance with U.S. GAAP are omitted. In the opinion of management, all adjustments consisting solely of normal recurring accruals considered necessary for the fair statement of consolidated financial statements for the interim periods have been included. The current period’s results of operations are not necessarily indicative of results that ultimately may be achieved for the full fiscal year. Therefore, the interim unaudited consolidated financial statements and notes should be read in conjunction with the audited consolidated financial statements and notes thereto for the year ended December 31, 2024. The year-end Consolidated Statements of Assets and Liabilities data was derived from audited financial statements but does not include all disclosures required by U.S. GAAP. The Company’s functional currency is U.S. dollars (“USD”) and these consolidated financial statements have been prepared in that currency.

As an investment company, the Company follows accounting and reporting guidance as set forth in Topic 946, Financial Services – Investment Companies (“ASC Topic 946”) of the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification, as amended (“ASC”). As provided under Regulation S-X and ASC Topic 946, the Company will 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. Rather, an investment company’s interest in portfolio companies that are not investment companies should be measured at fair value in accordance with ASC Topic 946. The Adviser Subsidiary is not an investment company as defined in ASC Topic 946 and further, the Adviser Subsidiary provides investment advisory services exclusively to the Adviser Funds which are owned by External Parties. As such, pursuant to ASC Topic 946, the Adviser Subsidiary is accounted for as a portfolio investment of the Company held at fair value and is not consolidated.

Financial statements prepared on a U.S. GAAP basis require management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the consolidated financial statements and the reported amounts of income, expenses, gains and losses during the reported periods. Changes in the economic and regulatory environment, financial markets, the credit worthiness of our portfolio companies, other macro-economic developments (for example, global pandemics, natural disasters, terrorism, international conflicts and war), and any other parameters used in determining these estimates and assumptions could cause actual results to differ from these estimates and assumptions.

Principles of Consolidation

The Consolidated Financial Statements include the accounts of the Company, its consolidated subsidiaries, and all Variable Interest Entities (“VIE”) of which the Company is the primary beneficiary. All intercompany accounts and transactions have been eliminated in consolidation.

A VIE is an entity that either (i) has insufficient equity to permit the entity to finance its activities without additional subordinated financial support or (ii) has equity investors who lack the characteristics of a controlling financial interest. The primary beneficiary of a VIE is the party with both the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance and the obligation to absorb the losses or the right to receive benefits that could be significant to the VIE.

To assess whether the Company has the power to direct the activities of a VIE that most significantly impact its economic performance, the Company considers all the facts and circumstances including its role in establishing the VIE and its ongoing rights and responsibilities. This assessment includes identifying the activities that most significantly impact the VIE’s economic performance and identifying which party, if any, has power over those activities. In general, the party that makes the most significant decisions affecting the VIE is determined to have the power to direct the activities of a VIE. To assess whether the Company has the obligation to absorb the losses or the right to receive benefits that could potentially be significant to the VIE, the Company considers all of its economic interests, including debt and equity interests, servicing rights and fee arrangements, and any other variable interests in the VIE. If the Company determines that it is the party with the power to make the most significant decisions affecting the VIE, and the Company has a potentially significant interest in the VIE, then it consolidates the VIE.

The Company performs periodic reassessments, usually quarterly, of whether it is the primary beneficiary of a VIE. The reassessment process considers whether the Company has acquired or divested the power to direct the activities of the VIE through changes in governing documents or other circumstances. The Company also reconsiders whether entities previously determined not to be VIEs have become VIEs, based on certain events, and therefore are subject to the VIE consolidation framework.

The Company's Consolidated Financial Statements included the accounts of the securitization trust, a VIE, formed in 2022 in conjunction with the issuance of the 2031 Asset-Backed Notes (as defined in “Note 5 – Debt”). The assets of the Company's securitization VIE are restricted to be used to settle obligations of its consolidated securitization VIE, which are disclosed parenthetically on the Consolidated Statements of Assets and Liabilities. The liabilities are the only obligations of its consolidated securitization VIE, and the creditors (or beneficial interest holders) do not have recourse to the Company's general credit.

Fair Value Measurements

The Company follows guidance in ASC Topic 820, Fair Value Measurement (“ASC Topic 820”), where fair value is defined 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 Topic 820 establishes a framework for measuring the fair value of assets and liabilities and outlines a three-tier hierarchy which maximizes the use of observable market data input and minimizes the use of unobservable inputs to establish a classification of fair value measurements. Inputs refer broadly to the assumptions that market participants would use in pricing the asset or liability, including assumptions about risk, such as the risk inherent in a particular valuation technique used to measure fair value using a pricing model and/or the risk inherent in the inputs for the valuation technique. Inputs may be observable or unobservable. Observable inputs reflect the assumptions market participants would use in pricing the asset or liability based on market data obtained from sources independent of the Company. Unobservable inputs reflect the Company’s own assumptions about the assumptions market participants would use in pricing the asset or liability based on the information available. The inputs or methodology used for valuing assets or liabilities may not be an indication of the risks associated with investing in those assets or liabilities. ASC Topic 820 also requires disclosure for fair value measurements based on the level within the hierarchy of the information used in the valuation. ASC Topic 820 applies whenever other standards require (or permit) assets or liabilities to be measured at fair value.

The Company categorizes all investments recorded at fair value in accordance with ASC Topic 820 based upon the level of judgment associated with the inputs used to measure their fair value. Hierarchical levels, defined by ASC Topic 820 and directly related to the amount of subjectivity associated with the inputs to fair valuation of these assets and liabilities, are as follows:

Level 1—Inputs are unadjusted, quoted prices in active markets for identical assets at the measurement date. The types of assets carried at Level 1 fair value generally are equities listed in active markets.

Level 2—Inputs (other than quoted prices included in Level 1) are either directly or indirectly observable for the asset in connection with market data at the measurement date and for the extent of the instrument’s anticipated life. Fair valued assets that are generally included in this category are publicly held debt investments and warrants held in a public company.

Level 3—Inputs reflect management’s best estimate of what market participants would use in pricing the asset at the measurement date. It includes prices or valuations that require inputs that are both significant to the fair value measurement and unobservable. Generally, assets carried at fair value and included in this category are the debt investments and warrants and equities held in a private company.

Valuation of Investments

The most significant estimate inherent in the preparation of the Company’s consolidated financial statements is the valuation of investments and the related amounts of unrealized appreciation and depreciation of investments recorded.

Pursuant to Rule 2a-5 under the 1940 Act, the Board has designated a group of the Company’s executive officers and senior employees to serve as the Board’s “valuation designee” (such group of executive officers and senior employees are referred to herein as the “Valuation Committee”). As of June 30, 2025, approximately 97.5% of the Company’s total assets represented investments in portfolio companies whose fair value is determined in good faith by the Company's Valuation Committee and approved by the Board. Fair Value, as defined in Section 2(a)(41) of the 1940 Act, is (i) the market price for those securities for which a market quotation is readily available and (ii) for all other securities and assets, fair value is as determined in good faith by the Valuation Committee, as valuation designee of the Board. The Company’s investments are carried at fair value in accordance with Rule 2a-5 under the 1940 Act and ASC Topic 946. Given the Company's investment strategy, nature of investments, and types of businesses in which it invests, substantially all of the Company’s investments are considered Level 3 assets under ASC Topic 820 because there generally is no known or accessible market or market indexes for these investment securities to be traded or exchanged. As such, the Company values substantially all of its investments at fair value as determined in good faith pursuant to the valuation guidelines approved by the Board in accordance with the provisions of ASC Topic 820 and the 1940 Act. Due to the inherent uncertainty in determining the fair value of investments that do not have a readily available market values, the fair value of the Company’s investments may differ significantly from the value that would have been used had a readily available market existed for such investments, and the differences could be material.

In accordance with procedures approved by its Board, the Company values investments on a quarterly basis following a multistep valuation process. The quarterly Board approved multi-step valuation process is described below:

(1)The Company’s quarterly valuation process begins with each portfolio company being initially valued by the investment professionals responsible for the portfolio investment;

(2)Preliminary valuation conclusions and business-based assumptions, along with any applicable fair value marks provided by an independent firm, are reviewed with the Company’s investment committee and certain member(s) of credit group as necessary;

(3)The Valuation Committee reviews the preliminary valuations recommended by the investment committee and certain member(s) of the credit group of each investment in the portfolio and determines the fair value of each investment in the Company’s portfolio in good faith and recommends the valuation determinations to the Audit Committee of the Board;

(4)The Audit Committee of the Board provides oversight of the quarterly valuation process in accordance with Rule 2a-5, which includes a review of the quarterly reports prepared by the Valuation Committee, reviews the fair valuation determinations made by the Valuation Committee, and approves such valuations for inclusion in public reporting and disclosures, as appropriate; and

(5)The Board, upon the recommendation of the Audit Committee, discusses valuations and approves the fair value of each investment in the Company’s portfolio.

Investments purchased within the preceding two calendar quarters before the valuation date and debt investments with remaining maturities within 12 months or less may each be valued at cost with interest accrued or discount accreted/premium amortized to the date of maturity, unless such valuation, in the judgment of the Company, does not represent fair value. In this case such investments shall be valued at fair value as determined in good faith by the Valuation Committee and approved by the Board. Investments that are not publicly traded or whose market quotations are not readily available are valued at fair value as determined in good faith by the Valuation Committee subject to oversight and approval of the Board.

As part of the overall process noted above, the Company engages one or more independent valuation firm(s) to provide management with assistance in determining the fair value of selected portfolio investments each quarter. In selecting which portfolio investments to engage an independent valuation firm, the Company considers a number of factors, including, but not limited to, the potential for material fluctuations in valuation results, size, credit quality, and the time lapse since the last valuation of the portfolio investment by an independent valuation firm. The scope of services rendered by the independent valuation firm is at the discretion of the Valuation Committee and subject to approval of the Board, and the Company may engage an independent valuation firm to value all or some of our portfolio investments. In determining the fair value of a portfolio investment in good faith, the Company recognizes these determinations are made using the best available information that is knowable or reasonably knowable. In addition, changes in the market environment, portfolio company performance and other events that may occur over the duration of the investments may cause the gains or losses ultimately realized on these investments to be materially different than the valuations currently assigned. The change in fair value of each individual investment is recorded as an adjustment to the investment's fair value and the change is reflected in unrealized appreciation or depreciation.

The Company records unrealized depreciation on investments when it believes that an investment has decreased in value, including where it believes collection of a debt investment is doubtful or, if under the in-exchange premise, when it believes the value of a debt investment is less than the amortized cost of the investment. Conversely, where appropriate, the Company records unrealized appreciation if it believes that the underlying portfolio company has appreciated in value and, therefore, that its investment has also appreciated in value or, if it believes, under the in-exchange premise, the value of an investment is greater than its amortized cost.

Debt Investments

The Company’s debt investments are substantially considered Level 3 assets under ASC Topic 820 with fair value as

determined in good faith pursuant to the process described above. In making a good faith determination of the value of the Company’s investments, the Company generally starts with the cost basis of the investment, which includes the value attributed to the original issue discount (“OID”), if any, and payment-in-kind (“PIK”) interest or other receivables which have been accrued as earned. The Company then applies the valuation methods as set forth below.

The Company assumes the sale of each debt security in a hypothetical market to a hypothetical market participant where buyers and sellers are willing participants. The hypothetical market does not include scenarios where the underlying security was simply repaid or extinguished, but includes an exit concept. The Company determines the yield at inception for each debt investment. The Company then uses senior secured, leveraged loan yields provided by third party providers to calibrate the change in market yields between inception of the debt investment and the measurement date. Industry specific indices and other relevant market data are used to benchmark and assess market-based movements for reasonableness. As part of determining the fair value, the Company also evaluates the collateral for recoverability of the debt investments. The Company considers each portfolio company’s credit rating, security liens and other characteristics of the investment to adjust the baseline yield to derive a credit adjusted hypothetical yield for each investment as of the measurement date. The anticipated future cash flows from each investment are then discounted at the hypothetical yield to estimate each investment’s fair value as of the measurement date. The Company’s process includes an analysis of, among other things, the underlying investment performance, the current portfolio company’s financial condition and market changing events that impact valuation, estimated remaining life, current market yield and interest rate spreads of similar securities as of the measurement date.

The Company values debt securities that are traded on a public exchange at the prevailing market price as of the valuation date. The Company values syndicated debt investments, for which sufficient liquidity and market data are available, using broker quotes and bond indices amongst other factors. Debt investments with market quotations are generally considered Level 1 or 2 assets in line with ASC Topic 820. If there is a significant deterioration of the credit quality of a debt investment, the Company may consider other factors to estimate fair value, including the proceeds that would be received in a liquidation analysis.

When originating a debt instrument, the Company generally receives warrants or other equity securities from the borrower. The Company determines the cost basis of the warrants or other equity securities received based upon their respective fair values on the date of receipt in proportion to the total fair value of the debt and warrants or other equity securities received. Any resulting discount on the debt investments from recording warrant or other equity instruments is accreted into interest income over the life of the debt investment.

Equity Securities and Warrants

Securities that are traded in the over-the-counter markets or on a stock exchange will be valued at the prevailing bid price at period end. The Company has a limited amount of equity securities in public companies. In accordance with the 1940 Act, unrestricted publicly traded securities for which market quotations are readily available are valued at the closing market quote on the measurement date.

At each reporting date, privately held warrant and equity securities are valued based on an analysis of various factors including, but not limited to, the portfolio company’s operating performance and financial condition, general market conditions, price to enterprise value or price to equity ratios, discounted cash flow, valuation comparisons to comparable public companies or other industry benchmarks. When an external event occurs, such as a purchase transaction, public offering, or subsequent equity sale, the pricing indicated by that external event is utilized to corroborate the Company’s valuation of the warrant and equity securities. The Company periodically reviews the valuation of its portfolio companies that have not been involved in a qualifying external event to determine if the enterprise value of the portfolio company may have increased or decreased since the last valuation measurement date. Absent a qualifying external event, the Company estimates the fair value of warrants using a Black Scholes OPM. For certain privately held equity securities, the income approach is used, in which the Company converts future amounts (for example, cash flows or earnings) to a net present value. The measurement is based on the value indicated by current market expectations about those future amounts. In following these approaches, the types of factors that the Company may take into account include, as relevant: applicable market yields and multiples, the portfolio company’s capital structure, the nature and realizable value of any collateral, the portfolio company’s ability to make payments, its earnings and discounted cash flows, and enterprise value among other factors.

Investment Funds & Vehicles

The Company applies the practical expedient provided by the ASC Topic 820 relating to investments in certain entities that calculate net asset value (“NAV”) per share (or its equivalent). ASC Topic 820 permits an entity holding investments in certain entities that either are investment companies, or have attributes similar to an investment company, and calculate NAV per share or its equivalent for which the fair value is not readily determinable, to measure the fair value of such investments on the basis of that NAV per share, or its equivalent, without adjustment. Investments which are valued using NAV per share as a practical expedient are not categorized within the fair value hierarchy as per ASC Topic 820.

Derivative Instruments

The Company's derivative instruments include foreign currency forward contracts. The Company recognizes all derivative instruments as assets or liabilities at fair value in its consolidated financial statements. Derivative contracts entered into by the Company are not designated as hedging instruments, and as a result, the Company presents changes in fair value through net change in unrealized appreciation (depreciation) on non-control/non-affiliate investments in the Consolidated Statements of Operations. Realized gains and losses of the derivative instruments are included in net realized gains (losses) on non-control/non-affiliate investments in the Consolidated Statements of Operations. The net cash flows realized on settlement of derivatives are included in realized (gain) loss in the Consolidated Statements of Cash Flows.

Cash, Cash Equivalents, Foreign Cash, and Restricted Cash

Cash and cash equivalents consist solely of funds deposited with financial institutions and short-term liquid investments in money market deposit accounts. Cash and cash equivalents are carried at cost, which approximates fair value. Foreign cash includes the value of foreign currencies held and translated using the prevailing foreign exchange rates on the reporting date. Restricted cash includes amounts that are held as collateral securing certain of the Company’s financing transactions, including amounts held in a securitization trust by trustees related to its 2031 Asset-Backed Notes (refer to “Note 5 – Debt”).

Foreign Currency Translation

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

Other Assets

Other assets generally consist of prepaid expenses, debt issuance costs related to our Credit Facilities (as defined below) net of accumulated amortization, fixed assets net of accumulated depreciation, deferred revenues and deposits and other assets, including escrow and other investment related receivables.

Escrow Receivables

Escrow receivables are collected in accordance with the terms and conditions of the escrow agreement. Escrow balances are typically distributed over a period greater than one year and may accrue interest during the escrow period. Escrow balances are measured for collectability on at least a quarterly basis and fair value is determined based on the amount of the estimated recoverable balances and the contractual maturity date.

Leases

The Company determines if an arrangement is a lease at inception. Operating leases are included in right-of-use (“ROU”) assets, and operating lease liability obligations in our Consolidated Statements of Assets and Liabilities. The Company recognizes a ROU asset and an operating lease liability for all leases, with the exception of short-term leases which have a term of 12 months or less. ROU assets represent the right to use an underlying asset for the lease term and operating lease liability obligations represent the obligation to make lease payments arising from the lease. ROU assets and liabilities are recognized at lease commencement date based on the present value of lease payments over the lease term. The Company has lease agreements with lease and non-lease components and has separated these components when determining the ROU assets and the related lease liabilities. As most of the Company’s leases do not provide an implicit rate, the Company estimated its incremental borrowing rate based on the information available at the lease commencement date in determining the present value of lease payments. The Company uses the implicit rate when readily determinable. The ROU asset also includes any lease payments made and excludes lease incentives and lease direct costs. The Company’s lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense is recognized on a straight-line basis over the lease term. See “Note 11 – Commitments and Contingencies”.

Investment Income Recognition

The Company’s investment portfolio generates interest, fee, and dividend income. The Company records interest income on an accrual basis, recognizing income as earned in accordance with the contractual terms of the loan agreement, to the extent that such amounts are expected to be collected. The Company’s Structured Debt investments may generate OID related income. "Structured Debt" refers to a debt investment that is structured with an equity, warrant, option, or other right to purchase or convert into common or preferred equity investments. The OID recorded upfront typically represents the value of detachable equity, warrants, or another asset obtained in conjunction with the acquisition of debt securities. The OID value is accreted into interest income over the term of the loan as a yield enhancement following the effective interest method. Additionally, certain debt investments in the Company’s portfolio earn PIK interest. The Company records PIK interest in accordance with the contractual terms of the loan agreement, to the extent that such amounts are expected to be collected. Contractual PIK interest represents contractually deferred interest that is added to the loan balance as principal and is generally due at the end of the loan term.

Additionally, the Company’s loan origination activities generate fee income, which is generally collected in advance and includes loan commitment, facility fees for due diligence and structuring, as well as fees for transaction services and management services rendered by the Company to portfolio companies and other third parties. Loan commitment and facility fees are capitalized and then amortized into income over the contractual life of the loan using the effective interest method. One-off fees for transaction and management services are generally recognized as income in the period when the services are rendered. The Company may also earn loan exit fees, which are contractual fees that are generally received upon the earlier of maturity or prepayment. The Company accretes loan exit fees into interest income following the effective interest method, recognizing income as earned in accordance with the contractual terms of the loan agreement, to the extent that such amounts are expected to be collected.

From time to time, additional fees may be earned by the Company relating to specific loan modifications, prepayments, or other one-off events. These non-recurring fees are either amortized into fee income over the remaining term of the loan commencing in the quarter for loan modifications, or recognized currently as one-time fee income for items such as prepayment penalties, fees related to select covenant default waiver fees, and acceleration of previously deferred loan fees and OID related to early loan pay-off or material modification of the specific debt outstanding.

Debt investments are placed on non-accrual status when it is probable that principal, interest or fees will not be collected according to contractual terms. When a debt investment is placed on non-accrual status, the Company ceases to recognize interest and fee income until the portfolio company has paid all principal and interest due or demonstrated the ability to repay its current and future contractual obligations to the Company. The Company may determine to continue to accrue interest on a loan where the investment has sufficient collateral value to collect all of the contractual amount due and is in the process of collection. Interest collected on non-accrual investments are generally applied to principal.

Dividend income is recorded on the record date for private portfolio companies or on the ex-dividend date for publicly traded portfolio companies to the extent that such amounts are payable by the portfolio company and are expected to be collected.

Realized Gains or Losses

Realized gains or losses are measured by the difference between the net proceeds from the sale or other realization event and the cost basis of the investment using the specific identification method without regard to unrealized appreciation or depreciation previously recognized, and includes investments charged off during the period, net of recoveries.

Secured Borrowings

The Company follows the guidance in ASC Topic 860, Transfers and Servicing (“ASC Topic 860”), when accounting for participation and other partial loan sales. Certain loan sales do not qualify for sale accounting under ASC Topic 860 because these sales do not meet the definition of a “participating interest”, as defined in the guidance, in order for sale accounting treatment to be allowed. Participations or other partial loan sales which do not meet the definition of a participating interest, or which are not eligible for sale accounting treatment remain as an investment on the consolidated balance sheet as required under U.S. GAAP and the proceeds are recorded as a secured borrowing. Secured borrowings are carried at fair value.

Equity Offering Expenses

The Company’s offering expenses are charged against the proceeds from equity offerings when received as a reduction of capital upon completion of an offering of registered securities.

Debt

The debt of the Company is carried at amortized cost which is comprised of the principal amount borrowed net of any unamortized discount and debt issuance costs. Discounts and issuance costs are accreted to interest expense and loan fees, respectively, using the straight-line method, which closely approximates the effective yield method, over the remaining life of the underlying debt obligations (see “Note 5 – Debt”). Accrued but unpaid interest is included within Accounts payable and accrued liabilities on the Consolidated Statements of Assets and Liabilities. In the event that the debt is extinguished, either partially or in full, before maturity, the Company recognizes the gain or loss in the Consolidated Statements of Operations within net realized gains (losses) as a “Loss on extinguishment of debt”.

Debt Issuance Costs

Debt issuance costs are fees and other direct incremental costs incurred by the Company in obtaining debt financing and are recognized as prepaid expenses and amortized over the life of the related debt instrument using the effective yield method or the straight-line method, which closely approximates the effective yield method. In accordance with ASC Subtopic 835-30, Interest – Imputation of Interest, debt issuance costs are presented as a reduction to the associated liability balance on the Consolidated Statements of Assets and Liabilities, except for debt issuance costs associated with line-of-credit arrangements which are included within Other Assets as permitted under GAAP.

Stock-Based Compensation

The Company has issued and may, from time to time, issue stock options, restricted stock, and other stock-based compensation awards to employees and directors. Management follows the guidance set forth under ASC Topic 718, to account for stock-based compensation awards granted. Under ASC Topic 718, compensation expense associated with stock-based compensation is measured at the grant date based on the fair value of the award and is recognized over the vesting period. Determining the appropriate fair value model and calculating the fair value of stock-based awards at the grant date requires judgment. This includes certain assumptions such as stock price volatility, forfeiture rate, expected outcome probability, and expected option life, as applicable to each award. In accordance with ASC Topic 480, certain stock awards are classified as a liability. The compensation expense associated with these awards is recognized in the same manner as all other stock-based compensation. The award liability is recorded as deferred compensation and included in Accounts payable and accrued liabilities.

Income Taxes

The Company accounts for income taxes in accordance with the provisions of ASC Topic 740 Income Taxes, under which income taxes are provided for amounts currently payable and for amounts deferred based upon the estimated future tax effects of differences between the financial statements and tax basis of assets and liabilities given the provisions of the enacted tax law. Valuation allowances may be used to reduce deferred tax assets to the amount likely to be realized.

Because taxable income as determined in accordance with U.S. federal tax regulations differ from U.S. GAAP, taxable income generally differs from net income for financial reporting purposes due to temporary and permanent differences in the recognition of income and expenses, and generally excludes net unrealized appreciation or depreciation, as such gains or losses are not included in taxable income until they are realized. Permanent differences are reclassified among capital accounts in the financial statements to reflect their appropriate tax character. Permanent differences may also result from the change in the classification of certain items, such as the treatment of short-term gains as ordinary income for tax purposes. Temporary differences arise when certain items of income, expense, gains or losses are recognized at some time in the future for tax or U.S. GAAP purposes.

The Company has elected to be treated as a RIC under Subchapter M Part I of the Code. To qualify as a RIC, the Company is required to meet certain income and asset tests in addition to distributing dividends of an amount generally at least equal to 90% of its investment company taxable income, as defined by the Code and determined without regard to any deduction for distributions paid, to its stockholders. See “Certain United States Federal Income Tax Considerations” included in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2024 filed with the SEC on February 13, 2025 for additional information.

As a RIC, the Company is subject to a 4% non-deductible U.S. federal excise tax on certain undistributed income unless the Company makes distributions treated as dividends for U.S. federal income tax purposes in a timely manner to its stockholders in respect of each calendar year of an amount at least equal to the sum of (1) 98% of its ordinary income (taking into account certain deferrals and elections) for each calendar year, (2) 98.2% of its capital gain net income (adjusted for certain ordinary losses) for the 1-year period ending October 31 of each such calendar year and (3) any ordinary income and capital gain net income realized, but not distributed, in preceding calendar years. The Company will not be subject to this excise tax on any amount on which the Company incurred U.S. federal income tax (such as the tax imposed on a RIC’s retained net capital gains).

The amount to be paid out as a distribution is determined by the Board each quarter and is based upon the annual earnings estimated by the management of the Company. To the extent that the Company's earnings fall below the amount of the dividend distributions declared, however, a portion of the total amount of the Company's distributions for the fiscal year may be deemed a return of capital.

Depending on the level of taxable income earned in a taxable year, the Company may choose to carry over taxable income in excess of current taxable year distributions from such taxable income into the next taxable year and incur a 4% excise tax on such taxable income, as required. The maximum amount of excess taxable income that may be carried over for distribution in the next taxable year under the Code is the total amount of distributions paid in the following taxable year, subject to certain declaration and payment guidelines. To the extent the Company chooses to carry over taxable income into the next taxable year, distributions declared and paid by the Company in a taxable year may differ from the Company’s taxable income for that taxable year as such distributions may include the distribution of current taxable year taxable income, the distribution of prior taxable year taxable income carried over into and distributed in the current taxable year, or returns of capital. The Company intends to timely distribute to its stockholders substantially all of its annual taxable income for each year, except that it may retain certain net capital gains for reinvestment and, depending upon the level of taxable income earned in a year, it may choose to carry forward taxable income for distribution in the following year and pay any applicable U.S. federal excise tax.

Earnings Per Share (“EPS”)

Basic EPS is calculated by dividing net earnings applicable to common stockholders by the weighted average number of common shares outstanding. Common shares outstanding includes common stock and restricted stock for which no future service is required as a condition to the delivery of the underlying common stock. Diluted EPS includes the determinants of basic EPS and, in addition, reflects the dilutive effect of the common stock deliverable pursuant to stock options and to restricted stock for which future service is required as a condition to the delivery of the underlying common stock. Diluted EPS is computed using the if-converted method for convertible debt, which reflects the potential dilution that would occur if all of the notes were converted as of the beginning of the reporting period (or the date of issuance, if later). The if-converted method is computed by dividing the net increase (decrease) in net assets resulting from operations (adjusted to reverse any recognized interest expense), by the weighted average number of shares of common stock assuming all potential shares had been converted, and the additional shares of common stock were dilutive. In accordance with ASC 260-10-45-60A, the Company uses the two-class method in the computation of basic EPS and diluted EPS, if applicable.

Comprehensive Income

The Company reports all changes in comprehensive income in the Consolidated Statements of Operations. The Company didnot have other comprehensive income for the three and six months ended June 30, 2025 or 2024. The Company’s comprehensive income is equal to its net increase in net assets resulting from operations.

Distributions

Distributions to common stockholders are approved by the Board on a quarterly basis and the distribution payable is recorded on the ex-dividend date. The Company maintains an “opt out” dividend reinvestment plan that provides for reinvestment of the Company’s distribution on behalf of the Company’s stockholders, unless a stockholder elects to receive cash. As a result, if the Company declares a distribution, cash distributions will be automatically reinvested in additional shares of its common stock unless the stockholder specifically “opts out” of the dividend reinvestment plan and chooses to receive cash distributions.

Segments

The Company has determined that it has a single operating segment in accordance with Topic 280, Segment Reporting (“ASC 280”). Our Chief Executive Officer is the Company’s Chief Operating Decision Maker (“CODM”). While the Company lends to and separately evaluates the performance of each portfolio company in which it invests across various technology-related industries including drug discovery and development, software, consumer & business services, and other healthcare services, the Company and the CODM evaluate and monitor performance of the business on an aggregated basis. Further, each investment is evaluated and managed using similar processes and shared operations support functions such as deal origination, underwriting, documentation, loan and compliance administration in addition to administrative functions of human resources, legal, finance and information technology.

The CODM uses our consolidated net investment income and net increase (decrease) in net assets resulting from operations as reported in the Consolidated Statements of Operations to assess the Company’s performance and when allocating resources. Net Investment Income is comprised of consolidated total investment income (‘segment revenues’) and consolidated total net operating expenses (‘significant segment expenses’), which are considered the key segment measures of profit or loss received by the CODM. The information and operating expense categories included in the Company’s Consolidated Statement of Operations are fully reflective of the significant expense categories and amounts that are regularly provided to the CODM.

3. Fair Value of Financial Instruments

The Company values financial instruments in accordance with ASC 820, using the techniques and approaches outlined in the Company's valuation guidelines, which are approved by the Board. During the periods ended June 30, 2025 and December 31, 2024, there were no changes to the Company’s valuation techniques or approaches as described herein.

Fair value estimates are made at discrete points in time based on relevant information. These estimates may be subjective in nature and involve uncertainties and matters of significant judgment and, therefore, cannot be determined with precision. Investments measured at fair value on a recurring basis are categorized in the tables below based upon the lowest level of significant input to the valuations as of June 30, 2025 and December 31, 2024.

(1)This investment is included in Cash and cash equivalents in the accompanying Consolidated Statements of Assets and Liabilities.

(2)Common stock includes non-voting security in the form of a promissory note with a lien on shares of issuer's common stock.

(3)In accordance with U.S. GAAP, certain investments are measured at fair value using the NAV per share (or its equivalent) as a practical expedient and are not categorized within the fair value hierarchy as per ASC 820. The fair value amounts presented in this table are intended to permit reconciliation of the fair value hierarchy to the amounts presented in the accompanying Consolidated Statements of Assets and Liabilities.

(4)Derivative Instruments are carried at fair value and are a Level 2 security within the Company's fair value hierarchy.

The table below presents a reconciliation of changes for all financial assets and liabilities measured at fair value on a recurring basis, excluding accrued interest components, using significant unobservable inputs (Level 3) for the six months ended June 30, 2025 and 2024.

• The Company recognizes transfers as of the transaction date.

(1)Included in net realized gains (losses) in the accompanying Consolidated Statements of Operations.

(2)Included in net change in unrealized appreciation (depreciation) in the accompanying Consolidated Statements of Operations.

(3)During the three months ended March 31, 2025, 23andMe, Inc. Level 1 common stock was converted into Level 3 common stock due to bankruptcy and delisting. Subsequently, during the three months ended June 30, 2025, 23andMe, Inc. was treated as Level 1 common stock due to resumed trading after reaching a definitive agreement during the bankruptcy proceeding. Transfers out of Level 3 debt investments during the six months ended June 30, 2025 related to the conversion of the Company's Level 3 debt investments in Hercules Adviser LLC, Carbon Health Technologies, Inc., and Khoros, LLC, into common stock Level 3 investments.

(4)Transfers out of Level 3 during the six months ended June 30, 2024 related to the conversion of the Company's Level 3 debt investments in Better Therapeutics, Inc. and Eigen Technologies Ltd. into common stock and preferred stock Level 3 investments in acquiring companies.

(5)Amounts listed above are inclusive of loan origination fees received at the inception of the loan which are deferred and amortized into fee income as well as the accretion of existing loan discounts and fees during the period. Escrow receivable purchases may include additions due to proceeds held in escrow from the liquidation of Level 3 investments. Amounts are net of purchases assigned to the Adviser Funds.

(6)Amounts listed above include the acceleration and payment of loan discounts and loan fees due to early payoffs or restructures along with regularly scheduled amortization.

The following table presents the net unrealized appreciation (depreciation) recorded for debt, preferred stock, common stock and warrant Level 3 investments relating to assets still held at the reporting date.

The following tables provide quantitative information about the Company’s Level 3 fair value measurements as of June 30, 2025 and December 31, 2024. In addition to the techniques and inputs noted in the tables below, according to the Company’s valuation guidelines, the Company may also use other valuation techniques and methodologies when determining the Company’s fair value measurements. The tables below are not intended to be all-inclusive, but rather provide information on the significant Level 3 inputs as they relate to the Company’s fair value measurements. See the accompanying Consolidated Schedule of Investments for the fair value of the Company’s investments. The methodology for the determination of the fair value of the Company’s investments is discussed in “Note 2 – Summary of Significant Accounting Policies”. The significant unobservable input used in the fair value measurement of the Company’s escrow receivables is the amount recoverable at the contractual maturity date of the escrow receivable.

(1)The significant unobservable inputs used in the fair value measurement of the Company’s debt securities are hypothetical market yields and premiums/(discounts). The hypothetical market yield is defined as the exit price of an investment in a hypothetical market to hypothetical market participants where buyers and sellers are willing participants. The premiums/(discounts) relate to company specific characteristics such as underlying investment performance, security liens, and other characteristics of the investment. Significant increases (decreases) in the inputs in isolation may result in a significantly lower (higher) fair value measurement, depending on the materiality of the investment.

Debt investments in the industries noted in the Company’s Consolidated Schedule of Investments are included in the industries noted above as follows:

•Pharmaceuticals, above, is comprised of debt investments in the “Drug Discovery & Development” and “Healthcare Services, Other” industries.

•Technology, above, is comprised of debt investments in the “Communications & Networking”, “Information Services”, “Consumer & Business Services”, “Media/Content/Info”, “Space Technologies”, “Defense Technologies”, and “Software” industries.

The Company believes that the carrying amounts of its financial instruments, other than investments and debt, which consist of cash and cash equivalents, receivables including escrow receivables, accounts payable and accrued liabilities, approximate the fair values of such items due to the short maturity of such instruments. The debt obligations of the Company are recorded at amortized cost and not at fair value on the Consolidated Statements of Assets and Liabilities. The fair value of the Company’s outstanding debt obligations are based on observable market trading prices or quotations and unobservable market rates as applicable for each instrument.

As of June 30, 2025 and December 31, 2024, the 2033 Notes (as defined in “Note 5 - Debt”) were trading on the New York Stock Exchange (“NYSE”) at $25.03 and $25.17 per unit at par value. The par value at underwriting for the 2033 Notes was $25.00 per unit. Based on market quotations on or around June 30, 2025 and December 31, 2024, the 2031 Asset-Backed Notes (as defined in “Note 5 - Debt”) were quoted for 0.972 and 0.963. Based on market quotations on or around June 30, 2025, the 2028 Convertible Notes (as defined in “Note 5 - Debt”) were quoted for 0.970 per dollar at par value. The fair values of the SBA debentures, March 2026 A Notes, March 2026 B Notes, September 2026, January 2027 Notes, and June 2030 Notes (each as defined in “Note 5 - Debt”) are calculated based on the net present value of payments over the term of the notes using estimated market rates for similar notes and remaining terms. The fair values of the outstanding debt under the MUFG Bank Facility and the SMBC Facility (each as defined in “Note 5 - Debt”) are equal to their outstanding principal balances as of June 30, 2025 and December 31, 2024.

4. Investments

Control and Affiliate Investments

As required by the 1940 Act, the Company classifies its investments by level of control. “Control investments” are defined in the 1940 Act as investments in those companies that the Company is deemed to “control”. Under the 1940 Act, the Company is generally deemed to “control” a company in which it has invested if it owns 25% or more of the voting securities of such company or has greater than 50% representation on its board. “Affiliate investments” are investments in those companies that are “affiliated companies” of the Company, as defined in the 1940 Act, which are not control investments. The Company is deemed to be an “affiliate” of a company in which it has invested if it owns 5% or more, but generally less than 25%, of the voting securities of such company. “Non-control/non-affiliate investments” are investments that are neither control investments nor affiliate investments. For purposes of determining the classification of its investments, the Company has included consideration of any voting securities or board appointment rights held by the Adviser Funds.

The following table summarizes the Company’s realized gains and losses and changes in unrealized appreciation and depreciation on control and affiliate investments for the three and six months ended June 30, 2025 and 2024.

Concentrations of Credit Risk

The Company’s customers are primarily privately held companies and public companies which are active in the “Software”, “Drug Discovery & Development”, “Healthcare Services, Other”, and “Consumer & Business Services” sectors. These sectors are characterized by high margins, high growth rates, consolidation and product and market extension opportunities. Value for companies in these sectors is often vested in intangible assets and intellectual property.

Industry and sector concentrations vary as new loans are recorded and loans are paid off. Investment income, consisting of interest, fees, and recognition of gains on equity and warrant or other equity interests, can fluctuate materially when a loan is paid off or a related warrant or equity interest is sold. Investment income recognized in any given year can be highly concentrated among several portfolio companies.

As of June 30, 2025 and December 31, 2024, the Company’s ten largest portfolio companies represented approximately 28.6% and 31.6%, respectively, of the total fair value of the Company’s investments in portfolio companies. As of June 30, 2025 and December 31, 2024, the Company hadsix andsix portfolio companies, respectively, that represented 5% or more of the Company’s net assets. As of June 30, 2025, the Company hadfour equity investments representing 58.1% of the total fair value of the Company's equity investments, and each represented 5% or more of the total fair value of the Company’s equity investments. As of December 31, 2024, the Company hadthree equity investments which represented approximately 49.7% of the total fair value of the Company’s equity investments, and each represented 5% or more of the total fair value of the Company’s equity investments.

MUFG Bank Facility

On June 10, 2025, the Company entered into a fourth amended credit facility agreement (the “Fourth Amendment”), which amends the agreement dated as of January 13, 2023. The Company, through a special purpose wholly owned subsidiary, Hercules Funding IV LLC (“Hercules Funding IV”), as borrower, entered into the credit facility (the “MUFG Bank Facility”) with MUFG Bank Ltd. as the arranger and administrative agent, and the lenders party to the MUFG Bank Facility from time to time.

The Fourth Amendment increased the lenders' commitments from $400.0 million to $440.0 million, which may be further increased via an accordion feature up to an aggregate $600.0 million, funded by existing or additional lenders and with the agreement of MUFG Bank and subject to other customary conditions. There can be no assurances that additional lenders will join the MUFG Bank Facility to increase available borrowings. The Fourth Amendment adjusted the interest rate per annum from SOFR plus 2.75% to SOFR plus an applicable margin adjustment which can range from 2.50% to 2.75% subject to certain conditions. The maturity date was amended from January 13, 2026, plus a twelve-month amortization period to June 10, 2029, unless sooner terminated in accordance with its terms. The MUFG Bank Facility is secured by all of the assets of Hercules Funding IV. The MUFG Bank Facility requires payment of a non-use fee at a rate based on average utilization rate during its term.

As of June 30, 2025, the SMBC Facility provides for borrowings in U.S. dollars and certain agreed upon foreign currencies of up to $300.0 million, from which the Company may access subject to certain conditions. The SMBC Facility contains an accordion feature, in which the Company can increase the credit line up to an aggregate of $500.0 million, funded by existing or additional lenders and with the agreement of SMBC Bank and subject to other customary conditions. Availability under the revolving SMBC Facility will terminate on November 24, 2028, and the outstanding loans under the SMBC Facility will mature on November 26, 2029. Borrowings under the SMBC Facility are subject to compliance with a borrowing base and an aggregate portfolio balance. The Company’s obligations under the SMBC Facility may in the future be guaranteed by certain of the Company’s subsidiaries and primarily secured by a first priority security interest (subject to certain exceptions) in only certain specified property and assets of the Company and the subsidiary guarantors thereunder.

Interest under the revolving portion of the SMBC Facility is determined by the nature and denomination of the borrowing. Interest rates are determined by the appropriate benchmark rate (SOFR, EURIBOR, Prime, CORRA, or TIBOR) as applicable for the type of borrowing plus an applicable margin adjustment which can range from 1.0% to 2.0% per annum subject to certain conditions. In addition to interest, the SMBC Facility is subject to a non-usage fee of 0.375% per annum (based on the immediately preceding period’s average usage) on the unused portion of the commitment under the SMBC Facility during the revolving period. The Company is required to pay letter of credit participation fees and a fronting fee on the average daily amount of any lender’s exposure with respect to any letters of credit issued under the SMBC Facility.

In connection with the Fifth Amendment, $25.0 million of the total available commitment under the revolver facility was converted into a term loan (the “SMBC Term Loan”). The SMBC Term loan is a SOFR based interest-bearing plus 2.0% spread loan and will mature on November 26, 2029, unless repurchased in accordance with the terms of the SMBC Facility. Interest on the SMBC Term Loan is payable monthly, quarterly, or semiannually based on the SOFR tenor. The SMBC Term Loan is general unsecured obligations and rank pari passu, or equally in right of payment, with all outstanding and future unsecured unsubordinated indebtedness issued by the Company. The Company may redeem some of all of SMBC Facility at any time, or from time to time, at the redemption price set forth under the terms of SMBC Facility Indenture.

On February 5, 2025, the Company entered into the Third Amendment to the SMBC Letter of Credit Facility Agreement (the "SMBC LC Facility"), which amends the SMBC LC Facility with Sumitomo Mitsui Banking Corporation, dated as of January 13, 2023. The SMBC LC Facility provides for a letter of credit facility with a final maturity date ending on February 5, 2028 and a commitment amount of $175.0 million as amended.

The SMBC Facility contains customary events of default with customary cure and notice provisions, including, without limitation, nonpayment, misrepresentation of representations and warranties in a material respect, breach of covenant, cross-default and cross-acceleration to other indebtedness and bankruptcy. The SMBC Facility also includes financial and other covenants applicable to the Company and the Company’s subsidiaries, including covenants relating to minimum stockholders' equity, asset coverage ratios, and our status as a RIC.

6. Income Taxes

The determination of taxable income pursuant to U.S. federal income tax regulations differs from U.S. GAAP. As a result, permanent differences are reclassified among capital accounts in the financial statements to reflect their appropriate tax character.

Taxable income and taxable net realized gains (losses) for the three and six months ended June 30, 2025 and 2024 appears as follows:

The aggregate gross unrealized appreciation (depreciation) of the Company’s investment over cost for U.S. federal income tax purposes appears as follows:

For the three and six months ended June 30, 2025, the Company paid approximately $0.3 million and $6.3 million, respectively, of income tax, including excise tax, and had $2.5 million of accrued, but unpaid tax expense as of June 30, 2025. For the three and six months ended June 30, 2024, the Company paid approximately $0.3 million and $5.2 million, respectively, of income tax, including excise tax, and had $3.4 million of accrued, but unpaid tax expense as of June 30, 2024.

Additionally, the Company has taxable subsidiaries which hold certain portfolio investments in an effort to limit potential legal liability and/or comply with source-income type requirements contained in the RIC tax provisions of the Code. These taxable subsidiaries are consolidated for U.S. GAAP and the portfolio investments held by the taxable subsidiaries are included in the Company’s consolidated financial statements and are recorded at fair value. These taxable subsidiaries are not consolidated with the Company for income tax purposes and may generate income tax expense, or benefit, and tax assets and liabilities as a result of their ownership of certain portfolio investments. Any income generated by these taxable subsidiaries generally would be subject to tax at normal U.S. federal tax rates based on its taxable income.

In accordance with ASC 740, the Company evaluates tax positions taken in the course of preparing the Company’s tax returns to determine whether the tax positions are “more-likely-than-not” to be sustained by the applicable tax authority. Tax benefits of positions not deemed to meet the more-likely-than-not threshold, or uncertain tax positions, would be recorded as a tax expense in the current year. It is the Company’s policy to recognize accrued interest and penalties, if any, related to unrecognized tax benefits as a component of provision for income taxes. Based on an analysis of the Company’s tax position, there are no uncertain tax positions that meet the recognition or measurement criteria. The Company is currently not undergoing any tax examinations. The Company does not anticipate any significant increase or decrease in unrecognized tax benefits for the next twelve months. The 2020 – 2023 federal tax years for the Company remain subject to examination by the Internal Revenue Service. The 2019 – 2023 state tax years for the Company remain subject to examination by the state taxing authorities.

7. Stockholders’ Equity and Distributions

The Company has issued and outstanding 181,729 thousand and 170,575 thousand shares of common stock as of June 30, 2025 and December 31, 2024, respectively. The Company currently sell shares through its equity distribution agreements (the “2024 Equity Distribution Agreements”) with Citizens JMP Securities LLC and Jefferies LLC (the “Sales Agents”) entered into on December 12, 2024. The 2024 Equity Distribution Agreements provide that the Company may offer and sell up to 30.0 million shares of its common stock from time to time through the Sales Agents. Sales of the Company's common stock, if any, may be made in negotiated transactions or transactions that are deemed to be “at the market,” as defined in Rule 415 under the Securities Act of 1933, as amended (the “Securities Act”), including sales made directly on the NYSE or similar securities exchange or sales made to or through a market maker other than on an exchange, at prices related to the prevailing market prices or at negotiated prices. The 2024 Equity Distribution Agreements replaced the ATM equity distribution agreements between the Company and the Sales Agents executed on May 5, 2023.

The Company issued and sold the following shares of common stock during the six months ended June 30, 2025 and 2024:

The Company generally uses net proceeds from these offerings to make investments, to repurchase or pay down liabilities and for general corporate purposes. As of June 30, 2025, approximately 19.6 million shares remain available for issuance and sale under the 2024 Equity Distribution Agreements.

The Company currently pays quarterly distributions to its stockholders. The following table summarizes the Company’s distributions declared during the six months ended June 30, 2025 and year ended December 31, 2024:

During the six months ended June 30, 2025, for income tax purposes, the distributions paid of $0.94 per share were comprised of ordinary income. As of June 30, 2025, the Company estimates that it has generated undistributed taxable earnings “spillover” of $0.74 per share. The undistributed taxable earnings spillover will be carried forward toward distributions to be paid in accordance with RIC requirements.

The Company has a distribution reinvestment plan, whereby the Company may buy shares of its common stock in the open market or issue new shares in order to satisfy dividend reinvestment requests. When the Company issues new shares in connection with the dividend reinvestment plan, the issue price is equal to the closing price of its common stock on the dividend record date. During the six months ended June 30, 2025 and 2024, the Company issued 264,860 and 205,697 shares, respectively, of common stock to stockholders in connection with the dividend reinvestment plan.

In connection with the issuance of shares under the 2018 Plan and Director Plan, the Company has registered, in aggregate,18.7 million and 300,000 shares of common stock, respectively.

The Company has received exemptive relief from the SEC that permits it to issue restricted stock to non-employee directors under the Director Plan and restricted stock and restricted stock units to certain of its employees, officers, and directors (excluding non-employee directors) under the 2018 Plan. The exemptive order also allows participants in the Director Plan and the 2018 Plan to (i) elect to have the Company withhold shares of its common stock to pay for the exercise price and applicable taxes with respect to an option exercise (“net issuance exercise”) and/or (ii) permit the holders of restricted stock to elect to have the Company withhold shares of its stock to pay the applicable taxes due on restricted stock at the time of vesting. Each individual employee would be able to make a cash payment to satisfy applicable tax withholding at the time of option exercise or vesting on restricted stock.

The Company has granted equity-based awards that have service and performance conditions. Certain of the Company’s equity-based awards are classified as liability awards in accordance with ASC Topic 718, Compensation – Stock Compensation. All of the Company’s equity-based awards require future service, and are expensed over the relevant service period. The Company does not estimate forfeitures, and reverses all unvested costs associated with equity-awards in the period they are forfeited. For the three months ended June 30, 2025 and 2024, the Company recognized $3.7 million and $3.3 million of stock-based compensation expense in the Consolidated Statements of Operations, respectively. For the six months ended June 30, 2025 and 2024, the Company recognized $7.3 million and $6.5 million of stock-based compensation expense in the Consolidated Statements of Operations, respectively. As of June 30, 2025 and June 30, 2024, approximately $26.5 million and $23.2 million of total unrecognized compensation costs expected to be recognized over the next 2.5 and 2.4 years, respectively.

Service Vesting Awards

The Company grants equity-based awards which have service conditions, which generally begin to vest one-third afterone year after the date of grant and ratably over the succeedingtwo years in accordance with the individual award terms. Certain awards have service conditions of longer duration and may begin to vest up toseven years after the date of grant. These equity-based awards which vest upon achievement of service conditions are collectively referred to as the “Service Vesting Awards”. The grant date fair value of Service Vesting Awards granted during the six months ended June 30, 2025 and 2024, were approximately $15.9 million, and $14.5 million, respectively.

The Company has granted restricted stock equity awards in the form of restricted stock awards and restricted stock units. The Company determines the grant date fair values of restricted stock equity awards using the grant date stock close price. The activities for the Company's unvested restricted stock equity awards for each of the six months ended June 30, 2025 and 2024, are summarized below:

In addition to the restricted stock equity-based awards, the Company has also issued stock options to certain employees. The fair value of options granted during the six months ended June 30, 2025 and 2024, was approximately $55 thousand and $39 thousand, respectively. During the six months ended June 30, 2025 and 2024, approximately $64 thousand, and $63 thousand of share-based cost due to stock option grants was expensed, respectively.

Liability Classified Awards

The Company has granted equity-based awards which are subject to both service and performance conditions. These awards are settled either in cash or a fixed dollar value of shares, subject to the terms of each individual award, and therefore classified as liability awards (the “Liability Awards”). As of June 30, 2025, all Liability Awards have vested and have been settled. Generally, if the performance conditions of these types of awards are not met, the total compensation expense related to the Liability Awards may be less than the maximum granted value of the awards. The Company records Liability Awards as deferred compensation within Accounts Payable and Accrued Liabilities included on the Consolidated Statements of Assets and Liabilities.

Certain Liability Awards are structured similar to the Performance Awards and increase in value with corresponding increases to the Company’s TSR and vest after four years. The Company remeasures the value of these awards each period based on the Company’s TSR achieved to date. Certain other Liability Awards are linked to attainment of investment funding goals. The Company determines the fair value of these Liability Awards based on the expected probability of the performance conditions being met and recognized over the service period. The Company accrues for Liability Awards based on the expected probability that the performance conditions would be met, this assumption is re-evaluated each period, and may be adjusted to reflect changes in this assumption. Generally, the other Liability Awards vest over athree-years service term.

During the six months ended June 30, 2025, no compensation expense related to the Liability Awards was recognized in the Consolidated Statements of Operations. As of June 30, 2025, no amounts remain outstanding. During the six months ended June 30, 2025, no Liability Awards vested.

During the six months ended June 30, 2024, approximately $0.5 million of compensation expense related to the Liability Awards was recognized in the Consolidated Statements of Operations. As of June 30, 2024, no amounts remain outstanding. During the six months ended June 30, 2024, $3.1 million Liability Awards were vested.

9. Earnings Per Share

Shares used in the computation of the Company’s basic and diluted earnings per share are as follows:

In the table above, unvested share-based payment awards that have non-forfeitable rights to distributions or distribution equivalents are treated as participating securities for calculating earnings per share. Unvested common stock options and restricted stock units are also considered for the purpose of calculating diluted earnings per share.

The issuance of the 2028 Convertible Notes is considered part of the if-converted method for calculation of diluted earnings per share. In applying the if-converted method, conversion is not assumed for purposes of computing diluted earnings per share if the effect would be anti-dilutive. For the three and six months ended June 30, 2025, there was no anti-dilution when applying the if-converted method for the 2028 Convertible Notes.

The calculation of change in net assets resulting from operations per common share assuming dilution, excludes all anti-dilutive shares. For the three and six months ended June 30, 2025 and 2024, the number of anti-dilutive shares, as calculated based on the weighted average closing price of the Company’s common stock for the periods, are as follows:

As of June 30, 2025 and December 31, 2024, the Company was authorized to issue 300.0 million shares of common stock with a par value of $0.001. Each share of common stock entitles the holder toone vote.

10. Financial Highlights

Following is a schedule of financial highlights for the six months ended June 30, 2025 and 2024:

(1)All per share activity is calculated based on the weighted average shares outstanding for the relevant period, except net increase (decrease) in net assets from capital share transactions, which is based on the common shares outstanding as of the relevant balance sheet date.

(2)Adjusts for the impact of stock-based compensation expense, which is a non-cash expense and has no net impact to NAV. Pursuant to ASC Topic 718, the expense is offset by a corresponding increase in paid-in capital. Additionally, adjusts for other items attributed to the difference between certain per share data based on the weighted-average basic shares outstanding and those calculated using the shares outstanding as of a period end or transaction date.

(3)The total return for the six months ended June 30, 2025 and 2024 equals to the change in the ending market value over the beginning of the period price per share plus distributions paid per share during the period, divided by the beginning price assuming the distribution is reinvested on the date of the distribution. As such, the total return is not annualized. The total return does not reflect any sales load that must be paid by investors.

(4)The ratios are calculated based on weighted average net assets for the relevant period and are annualized.

(5)The portfolio turnover rate for the six months ended June 30, 2025 and 2024 equals to the lesser of investment portfolio purchases or sales during the period, divided by the average investment portfolio value during the period. As such, portfolio turnover rate is not annualized.

(6)Includes distributions on unvested restricted stock awards.

11. Commitments and Contingencies

The Company’s commitments and contingencies consist primarily of unfunded commitments to extend credit in the form of loans to the Company’s portfolio companies. As of June 30, 2025, a portion of these unfunded contractual commitments are dependent upon the portfolio company reaching certain milestones before the debt commitment becomes available. Furthermore, the Company’s credit agreements with its portfolio companies generally contain customary lending provisions which allow the Company relief from funding obligations for previously made unfunded commitments in instances where the underlying portfolio company experiences materially adverse events that affect the financial condition or business outlook for the portfolio company. Since a portion of these commitments may expire without being drawn, unfunded contractual commitments do not necessarily represent future cash requirements. As such, the Company’s disclosure of unfunded contractual commitments includes only those which are available at the request of the portfolio company and unencumbered by future or unachieved milestones.

As of June 30, 2025 and December 31, 2024, the Company had approximately $471.5 million and $448.5 million, respectively, of available unfunded commitments, including undrawn revolving facilities, which were available at the request of the portfolio company and unencumbered by future or unachieved milestones. In order to draw a portion of the Company's available unfunded commitments, a portfolio company must submit to the Company a formal funding request that complies with the applicable advance notice and other operational requirements. The amounts disclosed exclude unfunded commitments (i) for which, with respect to a portfolio company's agreement, a milestone was achieved after the last day on which the portfolio company could have requested a drawdown funding to be completed within the reporting period; and (ii) related to the portion of portfolio company investments assigned to or directly committed by the Adviser Funds as described in “Note -12 Related Party Transactions”. The fair value of the Company’s unfunded commitments is considered to be immaterial as the yield determined at the time of underwriting is expected to be materially consistent with the yield upon funding, given that interest rates are generally pegged to market indices and given the existence of milestones, conditions and/or obligations embedded in the borrowing agreements.

As of June 30, 2025 and December 31, 2024, the Company’s unfunded contractual commitments available at the request of the portfolio company, including undrawn revolving facilities, and unencumbered by milestones were as follows:

(1)For debt investments, amounts represent unfunded commitments, including undrawn revolving facilities, which are available at the request of the portfolio company. Amount excludes unfunded commitments which are unavailable due to the borrower having not met certain milestones. These amounts also exclude $129.7 million and $139.7 million of unfunded commitments as of June 30, 2025 and December 31, 2024, respectively, to portfolio companies related to loans assigned to or directly committed by the Adviser Funds as described in “Note 12 - Related Party Transactions”.

(2)For investment funds and vehicles, the amount represents uncalled capital commitments in private equity funds.

Certain premises are leased or licensed under agreements which expire at various dates through July 2034. During the three months ended June 30, 2025 and 2024, total rent expense, including short-term leases, amounted to approximately $0.9 million and $0.9 million in each period, respectively. During the six months ended June 30, 2025 and 2024, total rent expense, including short-term leases, amounted to approximately $1.7 million and $1.9 million in each period, respectively. The Company recognizes an operating lease liability and a ROU asset for all leases, with the exception of short-term leases. The lease payments on short-term leases are recognized as rent expense on a straight-line basis. The discount rate applied to measure each ROU asset and lease liability is based on the Company’s incremental weighted average cost of debt. The Company considers the general economic environment and its credit rating and factors in various financing and asset specific adjustments to ensure the discount rate applied is appropriate to the intended use of the underlying lease. While some of the leases contained options to extend and terminate, it is not reasonably certain that either option will be utilized and therefore, only the payments in the initial term of the leases were included in the lease liability and ROU asset.

The following tables set forth information related to the measurement of the Company’s operating lease liabilities and supplemental cash flow information related to operating leases for the three and six months ended June 30, 2025 and 2024:

The following table shows future minimum lease payments under the Company’s operating leases and a reconciliation to the operating lease liability as of June 30, 2025:

The Company may, from time to time, be involved in litigation arising out of its operations in the normal course of business or otherwise. Furthermore, third parties may try to seek to impose liability on the Company in connection with the activities of its portfolio companies. While the outcome of any current legal proceedings cannot at this time be predicted with certainty, the Company does not expect any current matters will materially affect the Company’s financial condition or results of operations; however, there can be no assurance whether any pending legal proceedings will have a material adverse effect on the Company’s financial condition or results of operations in any future reporting period.
