FIDUS INVESTMENT Corp

GENERAL

Fidus Investment Corporation, a Maryland Corporation, operates as an externally managed business development company (“BDC”) under the Investment Company Act of 1940, as amended (“1940 Act”). FIC completed its initial public offering, or IPO, in June 2011. In addition, FIC has elected, and intends to qualify annually, to be treated as a regulated investment company (“RIC”) for U.S. federal income tax purposes under subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”). As of December 31, 2025, our shares were listed on the NASDAQ Global Select Market under the symbol “FDUS.”

FIC may make investments directly or through its two wholly-owned investment company subsidiaries, Fidus Mezzanine Capital III, L.P. (“Fund III”) and Fidus Mezzanine Capital IV, L.P. (“Fund IV” and together with Fund III, the “SBIC Funds”). Fidus Investment GP, LLC, the general partner of the SBIC Funds, is also a wholly owned subsidiary of FIC. The SBIC Funds are licensed by the U.S. Small Business Administration (the “SBA”) to operate as small business investment companies (“SBICs”). The SBIC Funds utilize the proceeds of the issuance of SBA-guaranteed debentures to enhance returns to our stockholders. Fidus Mezzanine Capital, L.P. (“Fund I”) and Fidus Mezzanine Capital II, L.P. (“Fund II”) have both completed their wind-down plans, can no longer issue additional SBA-guaranteed debentures, and relinquished their SBIC licenses on March 20, 2020 and March 7, 2024, respectively. We believe that utilizing both FIC and the SBIC Funds as investment vehicles provides us with access to a broader array of investment opportunities. Given our access to lower cost capital through the SBA’s SBIC debenture program, we expect that we will continue to make investments through the SBIC Funds during the investment period until the SBIC Funds reach their borrowing limit under the program. For two or more SBICs under common control, the maximum amount of outstanding SBA debentures cannot exceed $350.0 million.

Overview

We provide customized debt and equity financing solutions to lower middle-market companies, which we define as U.S. based companies having revenues between $10.0 million and $150.0 million. Our investment objective is to provide attractive risk-adjusted returns by generating both current income from our debt investments and capital appreciation from our equity related investments. Our investment strategy includes partnering with business owners, management teams and financial sponsors by providing customized financing for ownership transactions, recapitalizations, strategic acquisitions, business expansion and other growth initiatives. Although we are classified as a non-diversified investment company within the meaning of the 1940 Act, we maintain the flexibility to operate as a diversified investment company and have done so for an extended period of time. We seek to maintain a diversified portfolio of investments in order to help mitigate the potential effects of adverse economic events related to particular companies, regions or industries.

We invest in companies that possess some or all of the following attributes: predictable revenues; positive cash flows; defensible and/or leading market positions; diversified customer and supplier bases; and proven management teams with strong operating discipline. We target companies in the lower middle-market with annual earnings, before interest, taxes, depreciation and amortization, or EBITDA, between $5.0 million and $30.0 million; however, we may from time to time opportunistically make investments in larger or smaller companies. Our investments typically range between $5.0 million and $35.0 million per portfolio company.

As of December 31, 2025, we had debt and equity investments in 103 portfolio companies with an aggregate fair value of $1.3 billion. The weighted average yield on our debt investments as of December 31, 2025 was 12.6%. The weighted average yield of our debt investments is not the same as a return on investment for our stockholders but, rather, relates to a portion of our investment portfolio and is calculated before the payment of all of our fees and expenses. The weighted average yield was computed using the effective interest rates for debt investments at cost as of December 31, 2025, including accretion of original issue discount (“OID”) and loan origination fees, but excluding investments on non-accrual status and investments recorded as a secured borrowing. There can be no assurance that the weighted average yield will remain at its current level. For the year ended December 31, 2025, our total return based on net asset value (“NAV”) per share was 12.0% and our total return based on market value was 0.6%. For the year ended December 31, 2024, our total return based on NAV was 12.4% and our total return based on market value was 20.1%. Total return based on NAV per share equals the change in NAV per share during the period, plus dividends paid per share during the period, less other non-operating changes during the period, and divided by beginning NAV per share for the period. Non-operating changes include any items that affect NAV per share other than increase from investment operations, such as the effects of share issuances and repurchases and other miscellaneous items. Total return based on market value equals the change in the market value of our common stock per share during the period divided by the market value per share at the beginning of the period, and assumes reinvestment of dividends at prices obtained by our dividend reinvestment plan during the period. While these two figures reflect fund expenses, they do not reflect any sales load that may be paid by investors.

Our Advisor

Our investment activities are managed by Fidus Investment Advisors, LLC, our investment advisor, and supervised by our board of directors, a majority of whom are not “interested persons” of FIC as defined in section 2(a)(19) of the 1940 Act, and who we refer to hereafter as the Independent Directors. Pursuant to the terms of the investment advisory and management agreement, which we refer to as the Investment Advisory Agreement, between us and our investment advisor, our investment advisor is responsible for determining the composition of our portfolio, including sourcing potential investments, conducting research and diligence on potential investments and equity sponsors, analyzing investment opportunities, structuring our investments and monitoring our investments and portfolio companies on an ongoing basis. Our investment advisor’s investment professionals seek to capitalize on their significant deal origination and sourcing, underwriting, due diligence, investment structuring, execution, portfolio management and monitoring experience. These professionals have developed a broad network of contacts within the investment community, have gained extensive experience investing in assets that constitute our primary focus and have expertise in investing across all levels of the capital structure of lower middle-market companies.

Our relationship with our investment advisor is governed by and dependent on the Investment Advisory Agreement and may be subject to conflicts of interest. We pay our investment advisor a fee for its services under the Investment Advisory Agreement consisting of two components—a base management fee and an incentive fee. The base management fee is calculated at an annual rate of 1.75% of the average value of our total assets (other than cash or cash equivalents but including assets purchased with borrowed amounts). The incentive fee consists of two parts. The first part is calculated and payable quarterly in arrears and equals 20.0% of our “pre-incentive fee net investment income” for the immediately preceding quarter, subject to a 2.0% preferred return, or “hurdle,” and a “catch up” feature. The second part is determined and payable in arrears as of the end of each fiscal year in an amount equal to 20.0% of our realized capital gains, if any, on a cumulative basis from inception through the end of each fiscal year, computed net of all realized capital losses and unrealized capital depreciation on a cumulative basis, less the aggregate amount of any capital gain incentive fees paid in prior years. We accrue, but do not pay, a capital gains incentive fee in connection with any unrealized capital appreciation, as appropriate. For more information about how we compensate our investment advisor, see “Management and Other Agreements—Investment Advisory Agreement.”

Among other things, our board of directors is charged with protecting our interests by monitoring how our investment advisor addresses conflicts of interest associated with its management services and compensation. However, our board of directors periodically reviews our investment advisor’s portfolio management decisions and portfolio performance. In addition, our board of directors at least annually reviews the services provided by and fees paid to our investment advisor. In connection with these reviews, our board of directors, including a majority of our Independent Directors, considers whether the fees and expenses (including those related to leverage) that we pay to our investment advisor are fair and reasonable in relation to the services provided. Renewal of our Investment Advisory Agreement must be approved each year by our board of directors, including a majority of our Independent Directors.

Fidus Investment Advisors, LLC is a Delaware limited liability company that is registered as an investment advisor under the Investment Advisers Act of 1940, as amended, or the Advisers Act. In addition, Fidus Investment Advisors, LLC serves as our administrator and provides us with office space, equipment and clerical, book-keeping and record-keeping services pursuant to an administration agreement, which we refer to as the Administration Agreement.

Business Strategy

We intend to accomplish our goal of becoming one of the premier providers of capital to and value-added partner of lower middle-market companies by:

Leveraging the Experience of Our Investment Advisor. Our investment advisor’s investment professionals have significant experience investing in, lending to and advising companies across multiple industries and changing market cycles. These professionals have diverse backgrounds with prior experience in senior management positions at investment banks, specialty finance companies, commercial banks and privately and publicly held companies and have extensive experience investing across all levels of the capital structure of lower middle-market companies. We believe these professionals possess an in-depth understanding of the strategic, financial and operational challenges and opportunities of lower middle-market companies, enabling our investment advisor to effectively identify, assess, structure and monitor our investments.

Capitalizing on Our Strong Transaction Sourcing Network. Our investment advisor’s investment professionals possess an extensive network of long-standing relationships with private equity firms, middle-market senior lenders, junior capital partners, financial intermediaries and management teams of privately owned businesses. We believe that the combination of our investment advisor’s relationships and our reputation as a reliable, responsive and value-added financing partner helps us generate a steady stream of new investment opportunities and proprietary deal flow.

Serving as a Value-Added Partner with Customized Financing Solutions. We follow a partnership-oriented investment approach and focus on opportunities where we believe we can add value to a portfolio company. We primarily concentrate on industries or market niches in which the investment professionals of our investment advisor have prior experience. These professionals also have expertise in structuring securities at all levels of the capital structure, which we believe positions us well to meet the unique financing needs of our portfolio companies. We invest primarily in unitranche or first lien senior secured loans, typically coupled with an equity interest; however, on a selective basis we may invest in second lien and subordinated debt securities. Further, as a publicly-traded BDC, we have a longer investment horizon without the capital return requirements of traditional private investment vehicles. We believe this flexibility enables us to generate attractive risk-adjusted returns on invested capital and enables us to be a better long-term partner for our portfolio companies. We believe that by leveraging the industry and structuring expertise of our investment advisor coupled with our long-term investment horizon, we are well positioned to be a value-added partner for our portfolio companies.

Employing Rigorous Due Diligence and Underwriting Processes Focused on Capital Preservation. Our investment advisor follows a disciplined and credit-oriented approach to evaluating and investing in companies. We focus on companies with proven business models, significant free cash flow, defensible market positions and significant enterprise value cushion for our debt investments. In making investment decisions, we seek to minimize the risk of capital loss without foregoing the opportunity for capital appreciation. Our investment advisor’s investment professionals have developed extensive due diligence and underwriting processes designed to better assess a portfolio company’s prospects and to determine the appropriate investment structure. Our investment advisor thoroughly analyzes each potential portfolio company’s competitive position, financial performance, management team, growth potential and industry attractiveness. As part of this process, our investment advisor also participates in meetings with management, tours of facilities, discussions with industry professionals and third-party reviews. We believe this approach enables us to build and maintain an attractive investment portfolio that meets our return and value criteria over the long term.

Actively Managing our Portfolio. We believe that our investment advisor’s initial and ongoing portfolio review process allows us to effectively monitor the performance and prospects of our portfolio companies. We seek to obtain board observation rights or board seats with respect to our portfolio companies, and we conduct monthly financial reviews and have regular discussions with portfolio company management. We structure our investments with a comprehensive set of financial maintenance covenants, including affirmative and negative covenants. We believe that active monitoring of our portfolio companies’ compliance with covenants provides us with an early warning of any financial difficulty and enhances our ability to protect our invested capital.

Maintaining Portfolio Diversification. We seek to maintain a portfolio of investments that is appropriately diversified among companies, industries, geographic regions and end markets. We have made investments in portfolio companies in the following industries: business services, industrial products and services, value-added distribution, healthcare products and services, consumer products and services (including retail, food and beverage), energy services, aerospace, and defense manufacturing, transportation services, information technology services and niche manufacturing. We believe that investing across various industries helps mitigate the potential effects of negative economic events for particular companies, regions and industries.

Benefiting from Lower Cost of Capital. The SBIC Funds’ SBIC licenses allow us to issue SBA-guaranteed debentures. These SBA debentures carry long-term fixed rates that are generally lower than rates on comparable bank and public debt. Because lower-cost

SBA leverage is a significant part of our funding strategy, our relative cost of debt capital should be lower than many of our competitors. For two or more SBICs under common control, the maximum amount of outstanding SBA debentures cannot exceed $350.0 million.

Investments

We seek to create a diversified investment portfolio that primarily includes debt investments and, to a lesser extent, equity securities. Our investments typically range between $5.0 million to $35.0 million per portfolio company, although this investment size may vary proportionately with the size of our capital base. Our investment objective is to provide attractive risk-adjusted returns by generating both current income from our debt investments and capital appreciation from our equity related investments. We may invest in the equity securities of our portfolio companies, such as preferred stock, common stock, warrants and other equity interests, either directly or in conjunction with our debt investments.

First Lien Debt. We structure some of our investments as senior secured or first lien debt investments. First lien debt investments are secured by a first priority lien on existing and future assets of the borrower and may take the form of term loans or revolving lines of credit. First lien debt is typically senior on a lien basis to other liabilities in the issuer’s capital structure and has the benefit of a first-priority security interest in assets of the issuer. The security interest ranks above the security interest of any second lien lenders in those assets. Our first lien debt may include stand-alone first lien loans, “last out” first lien loans, or “unitranche” loans. Stand-alone first lien loans are traditional first lien loans. All lenders in the facility have equal rights to the collateral that is subject to the first-priority security interest. “Last out” first lien loans have a secondary priority behind super-senior “first out” first lien loans in the collateral securing the loans in certain circumstances. The arrangements for a “last out” first lien loan are set forth in an “agreement among lenders,” which provides lenders with “first out” and “last out” payment streams based on a single lien on the collateral. Since the “first out” lenders generally have priority over the “last out” lenders for receiving payment under certain specified events of default, or upon the occurrence of other triggering events under intercreditor agreements or agreements among lenders, the “last out” lenders bear a greater risk and, in exchange, receive a higher effective interest rate, through arrangements among the lenders, than the “first out” lenders or lenders in stand-alone first lien loans. Agreements among lenders also typically provide greater voting rights to the “last out” lenders than the intercreditor agreements to which second lien lenders often are subject.

Many of our debt investments also include excess cash flow sweep features, whereby principal repayment may be required before maturity if the portfolio company achieves certain defined operating targets. Additionally, our debt investments typically have principal prepayment penalties in the early years of the debt investment. The majority of our debt investments provide for a variable interest rate, generally with a Prime or SOFR floor.

Second Lien Debt. Some of our debt investments take the form of second lien debt, which includes senior subordinated notes. Second lien debt investments obtain security interests in the assets of the portfolio company as collateral in support of the repayment of such loans. Second lien debt typically is senior on a lien basis to other liabilities in the issuer’s capital structure and has the benefit of a security interest over assets of the issuer, though ranking junior to first lien debt secured by those assets. First lien lenders and second lien lenders typically have separate liens on the collateral, and an intercreditor agreement provides the first lien lenders with priority over the second lien lenders’ liens on the collateral. These loans typically provide for no contractual loan amortization, with all amortization deferred until loan maturity, and may include payment-in-kind (“PIK”) interest, which increases the principal balance over the term and, coupled with the deferred principal payment provision, increases credit risk exposure over the life of the loan.

Subordinated Debt. These investments are typically structured as unsecured, subordinated notes. Structurally, subordinated debt usually ranks subordinate in priority of payment to first lien and second lien debt and may not have the benefit of financial covenants common in first lien and second lien debt. Subordinated debt may rank junior as it relates to proceeds in certain liquidations where it does not have the benefit of a lien on specific collateral held by creditors (typically first lien and/or second lien) who have a perfected security interest in such collateral. However, subordinated debt ranks senior to common and preferred equity in an issuer’s capital structure. These loans typically have relatively higher fixed interest rates (often representing a combination of cash pay and PIK interest) and amortization of principal deferred to maturity. The PIK feature (meaning a feature allowing for the payment of interest in the form of additional principal amount of the loan instead of in cash), which effectively operates as negative amortization of loan principal, coupled with the deferred principal payment provision, increases credit risk exposure over the life of the loan.

Equity Securities. Our equity securities typically consist of either a direct minority equity investment in common or preferred stock or membership/partnership interests of a portfolio company, or we may receive warrants to buy a minority equity interest in a portfolio company in connection with a debt investment. Warrants we receive with our debt investments typically require only a nominal cost to exercise, and thus, as a portfolio company appreciates in value, we may achieve additional investment return from this equity interest. Our equity investments are typically not control-oriented investments, and in many cases, we acquire equity securities as part of a group of private equity investors in which we are not the lead investor. We may structure such equity investments to include provisions protecting our rights as a minority-interest holder, as well as a “put,” or right to sell such securities back to the issuer, upon the occurrence of specified events. In many cases, we may also seek to obtain registration rights in connection with these equity interests, which may include demand and “piggyback” registration rights. Our equity investments typically are made in connection with debt investments to the same portfolio companies.

Our Consolidated Portfolio

We generally seek to invest in companies from the broad range of industries in which our investment advisor has direct experience. The following is a representative list of the broad industry segments in which we have invested; however, we may invest in other industries if we are presented with attractive opportunities.

As of December 31, 2025, we had investments in 103 portfolio companies with an aggregate fair value of $1.3 billion. As of December 31, 2024, we had investments in 91 portfolio companies with an aggregate fair value of $1.1 billion.

The following table shows the portfolio composition by geographic region at fair value and cost and as a percentage of total investments (dollars in millions). The geographic composition is determined by the location of the corporate headquarters of the portfolio company, which may not be indicative of the primary source of the portfolio company’s business.

The following table shows the detailed industry segment composition of our portfolio at fair value and cost as a percentage of total investments.

Investment Criteria/Guidelines

We use the following criteria and guidelines in evaluating investment opportunities and constructing our portfolio. However, not all of these criteria and guidelines have been, or will be, met in connection with each of our investments.

Value Orientation / Positive Cash Flow. Our investment advisor places a premium on analysis of business fundamentals from an investor’s perspective and has a distinct value orientation. We focus on companies with proven business models in which we can invest at relatively low multiples of operating cash flow. We also typically invest in portfolio companies with a history of profitability and minimum trailing twelve month EBITDA of $5.0 million. We do not invest in start-up companies, “turn-around” situations or companies that we believe have unproven business plans.

Experienced Management Teams with Meaningful Equity Ownership. We target portfolio companies that have management teams with significant experience and/or relevant industry experience coupled with meaningful equity ownership. We believe management teams with these attributes are more likely to manage the companies in a manner that protects our debt investment and enhances the value of our equity investment.

Niche Market Leaders with Defensible Market Positions. We seek to invest in portfolio companies that have developed defensible and/or leading positions within their respective markets or market niches and are well-positioned to capitalize on growth opportunities. We favor companies that demonstrate significant competitive advantages, which we believe helps to protect their market position and profitability.

Diversified Customer and Supplier Base. We prefer to invest in portfolio companies that have a diversified customer and supplier base. Companies with a diversified customer and supplier base are generally better able to endure economic downturns, industry consolidation and shifting customer preferences.

Significant Equity Value. We believe the existence of significant underlying equity value provides important support to our debt investments. With respect to our debt investments, we look for portfolio companies where management/sponsors have provided significant equity funding and where we believe aggregate enterprise value significantly exceeds aggregate indebtedness, after consideration of our investment.

Viable Exit Strategy. We invest in portfolio companies that we believe will provide steady cash flows to service our debt, ultimately repay our loans and provide working capital for their respective businesses. In addition, we seek to invest in portfolio companies whose business models and expected future cash flows offer attractive exit possibilities for our portfolio equity investments. We expect to exit our investments typically through one of three scenarios: (a) the sale of the portfolio company resulting in repayment of all outstanding debt and monetization of equity; (b) the recapitalization of the portfolio company through which our investments are replaced with debt or equity from a third party or parties; or (c) the repayment of the initial or remaining principal amount of our debt investment from cash flow generated by the portfolio company. In some investments, there may be scheduled amortization of some portion of our debt investment that would result in a partial exit of our investment prior to the maturity of the debt investment.

Investment Committee

Our investment advisor has formed an investment committee to evaluate and approve all of our investments. The investment committee process is intended to bring the diverse experience and perspectives of the committee’s members to the analysis and consideration of each investment. The investment committee also serves to provide investment consistency and adherence to our investment advisor’s core investment philosophy and policies. The investment committee also determines appropriate investment sizing and suggests ongoing monitoring requirements.

The members of the investment committee that evaluate and approve all of our investments are Edward H. Ross, Thomas C. Lauer, John H. Grigg, Robert G. Lesley, Jr., Michael J. Miller, John J. Ross, II, and W. Andrew Worth.

Investment Process Overview

Our investment advisor has developed the following investment process based on the experience of its investment professionals to identify investment opportunities and to structure investments quickly and effectively. Furthermore, our investment advisor seeks to identify those companies exhibiting superior fundamental risk-reward profiles and strong defensible business franchises while focusing on the relative value of the security in the portfolio company’s capital structure. The investment process consists of five distinct phases:

Each of the phases is described in more detail below.

Investment Generation/Origination. Our investment origination efforts are focused on leveraging our investment advisor’s extensive network of long-standing relationships with private equity firms, middle-market senior lenders, junior-capital partners, financial intermediaries, service providers and management teams of privately owned businesses. We believe that our investment advisor’s investment professionals have reputations as reliable, responsive and value-added partners for lower middle-market companies. Our investment advisor’s focus and reputation as a value-added partner generates a balanced mix of proprietary deal flow and a steady stream of new deal opportunities.

Initial Evaluation. After a potential transaction is received by our investment advisor, it will conduct an initial review of the transaction materials to determine whether it meets our investment criteria and complies with SBA regulations (with respect to investments by the SBIC Funds) and other regulatory requirements.

If the potential transaction initially meets our investment criteria, at least two members of the investment committee, referred to as the deal team, will conduct a preliminary due diligence review, taking into consideration some or all of the following factors:

Upon successful completion of the screening process, the deal team prepares a screening memorandum and makes a recommendation to the investment committee. At this time, the investment committee will also consider whether the investment would be made by FIC and/or through the SBIC Funds. If the investment committee supports the deal team’s recommendation, the deal team issues a non-binding term sheet to the potential portfolio company. Such a term sheet will typically include the key economic terms based on our analysis conducted during the screening process. Upon agreement on a term sheet with the potential portfolio company, our investment advisor will begin a formal diligence and underwriting process.

Due Diligence and Underwriting. Our investment advisor has developed a rigorous and disciplined due diligence process that includes a comprehensive understanding of a borrower’s industry, market, operational, financial, organizational and legal positions and prospects. The due diligence review will take into account information that the deal team deems necessary to make an informed decision about the creditworthiness of the borrower and the risks of the investment, which includes some or all of the following:

During the due diligence process, significant attention is given to sensitivity analyses and how the portfolio company might be expected to perform given various scenarios, including downside, “base case” and upside. Upon satisfactory completion of the due diligence review process, the deal team will present their findings and a recommendation to the investment committee. If the investment committee supports the deal team’s recommendation, the deal team will proceed with negotiating and documenting the investment.

Documentation and Closing. Our investment advisor works with the management of a potential portfolio company and its other capital providers, including, as applicable, senior, junior and equity capital providers to structure an investment. Our investment advisor structures each investment with an acute focus on capital preservation and will tailor the terms of each investment to the facts and circumstances of the transaction and the prospective portfolio company. We seek to limit the downside of our investments by:

We expect to hold most of our investments to maturity or repayment, but may exit our investments earlier if a liquidity event takes place, such as a sale or recapitalization of a portfolio company, or if we determine that a sale of one or more of our investments is in our best interest.

Active Portfolio Management. Active portfolio monitoring is a vital part of our investment process and we continuously monitor the status and progress of the portfolio companies. The same deal team that was involved in the investment process will continue its involvement in the portfolio company post-investment. This provides for continuity of knowledge and allows the deal team to maintain a strong business relationship with key management of its portfolio companies for post-investment assistance and monitoring purposes.

As part of the monitoring process, the deal team conducts a comprehensive review of the financial and operating results of each portfolio company that includes a review of the monthly/quarterly financials relative to the prior year and budget, a review of the financial projections including cash flow and liquidity needs, meeting with management, attending board meetings and reviewing compliance certificates and covenants. We maintain an ongoing dialogue with the management and any controlling equity holders of a portfolio company that will include discussions about the company’s business plans and growth opportunities and any changes in industry and competitive dynamics. While we maintain limited involvement in the ordinary course operations of our portfolio companies, we may maintain a higher level of involvement in non-ordinary course financing or strategic activities and any non-performing scenarios. Our investment advisor’s portfolio management will also include quarterly portfolio reviews with all investment professionals and investment committee members.

Investment Rating System

In addition to various risk management and monitoring tools, our investment advisor uses an internally developed investment rating system to characterize and monitor the credit profile and our expected level of returns on each investment in our portfolio. We use a five-level numeric rating scale. The following is a description of the conditions associated with each investment rating:

The following table shows the distribution of our investments on the 1 to 5 investment rating scale at fair value and cost as of December 31, 2025 and 2024 (dollars in millions).

Based on our investment rating system, the weighted average rating of our portfolio as of December 31, 2025 and 2024 was 2.0 and 2.0, respectively, on a fair value basis and 2.2 and 2.2, respectively, on a cost basis.

Determination of Net Asset Value and Valuation Process

We determine the net asset value per share of our common stock on at least a quarterly basis, and more frequently if we are required to do so in connection with the issuance of shares of our common stock or pursuant to applicable federal laws and regulations. The net asset value per share of common stock is equal to the carrying value of our total assets minus liabilities and any preferred stock outstanding divided by the total number of shares of common stock outstanding. Our business plan calls for us to invest primarily in illiquid securities issued by private companies. These portfolio investments may be subject to restrictions on resale and will generally have no established trading market. Because there is not a readily available market for substantially all of the investments in our portfolio, we value substantially all of our portfolio investments at fair value as determined in good faith by our board of directors using a documented valuation policy and consistently applied valuation process in accordance with authoritative accounting guidelines. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Critical Accounting Policies and Use of Estimates – Valuation of Portfolio Investments.”

Competition

Our primary competitors in providing financing to lower middle-market companies include public and private funds, other BDCs, SBICs, commercial and investment banks, commercial financing companies and, to the extent they provide an alternative form of financing, private equity and hedge funds. Many of our competitors are substantially larger and have considerably greater financial, technical and marketing resources than we do. For example, we believe some competitors may have access to funding sources that are not available to us. In addition, some of our competitors may have higher risk tolerances or different risk assessments, which could allow them to consider a wider variety of investments and establish more relationships than us. Furthermore, many of our competitors are not subject to the regulatory restrictions that the 1940 Act imposes on us as a BDC or to the distribution and other requirements we must satisfy to maintain our RIC tax treatment.

We use the expertise of the investment professionals of our investment advisor to assess investment risks and determine appropriate pricing for our investments in portfolio companies. In addition, the relationships of the investment professionals of our investment advisor enable us to learn about, and compete effectively for, financing opportunities with attractive lower middle-market companies in the industries in which we seek to invest. For additional information concerning the competitive risks we face, see “Risk Factors — Risks Relating to Our Business and Structure — We operate in a highly competitive market for investment opportunities, which could reduce returns and result in losses.”

Human Resource Capital

We do not have any direct employees, and our day-to-day investment operations are managed by our investment advisor, which is also acting as our administrator. We have a chief executive officer, president, chief financial officer and chief compliance officer and, to the extent necessary, our board of directors may elect to hire additional personnel going forward. Our officers are employees of, and are compensated by, our investment advisor, and our allocable portion of the cost of our chief financial officer and chief compliance officer and their respective staffs are paid by us pursuant to the Administration Agreement. Some of our executive officers are also officers of our investment advisor. See “Management and Other Agreements — Administration Agreement.”

MANAGEMENT AND OTHER AGREEMENTS

Our investment advisor is located at 1603 Orrington Avenue, Suite 1005, Evanston, Illinois 60201. Our investment advisor also maintains additional office space at 4201 Congress Street, Suite 250, Charlotte, North Carolina 28209, and 1140 Avenue of the Americas, 21 st Floor, New York, New York 10036. Our investment advisor is registered as an investment adviser under the Advisers Act. Subject to the overall supervision of our board of directors and in accordance with the 1940 Act, our investment advisor manages our day-to-day operations and provides investment advisory services to us. Under the terms of the Investment Advisory Agreement, our investment advisor:

Investment Advisory Agreement

Management Fee

Pursuant to the Investment Advisory Agreement, we pay our investment advisor a fee for investment advisory and management services consisting of two components — a base management fee and an incentive fee.

Base Management Fee

The base management fee is calculated at an annual rate of 1.75% based on the average value of our total assets (other than cash or cash equivalents but including assets purchased with borrowed amounts) at the end of the two most recently completed calendar quarters, and appropriately adjusted for any share issuances or repurchases during the current calendar quarter. Base management fees for any partial quarter are appropriately prorated. The base management fee is payable quarterly in arrears.

Incentive Fee

The incentive fee consists of two parts. The first part is calculated and payable quarterly in arrears based on our pre-incentive fee net investment income for the 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 we receive 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 (defined below) and any interest expense and dividends paid on any outstanding preferred stock, but excluding the incentive fee and excise taxes on realized gains). Pre-incentive fee net investment income includes, in the case of investments with a deferred interest feature (such as market discount, debt instruments with PIK income, preferred stock with PIK dividends and zero-coupon securities), accrued income we have not yet received in cash. The Investment Advisor is not under any obligation to reimburse us for any part of the incentive fee it receives that was based on accrued interest that we never collect.

Pre-incentive fee net investment income does not include any realized capital gains, taxes associated with such realized capital gains, realized capital losses, unrealized capital appreciation or depreciation or realized losses on extinguishment of debt. Because of the structure of the incentive fee, it is possible that we may pay an incentive fee in a quarter where we incur a loss. For example, if we generate pre-incentive fee net investment income in excess of the hurdle rate (as defined below) for a quarter, we will pay the applicable incentive fee even if we have incurred a loss in that quarter due to a net loss on investments or realized losses on extinguishment of debt.

Pre-incentive fee net investment income, expressed as a rate of return on the value of our weighted average 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 2.0% per quarter. We may be able to invest our funds in debt instruments that provide for a higher return, which would increase our pre-incentive fee net investment income and make it easier for our investment advisor to surpass the fixed hurdle rate and receive an incentive fee based on such net investment income.

We pay our investment advisor an incentive fee with respect to our pre-incentive fee net investment income earned in each calendar quarter as follows:

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 following is a graphical representation of the calculation of the quarterly income-related portion of the incentive fee:

Quarterly Incentive Fee Based on Pre-Incentive Fee Net Investment Income

(expressed as a percentage of the value of net assets)

Percentage of pre-incentive fee net investment income

allocated to income-related portion of incentive fee

The second part of the incentive fee is a capital gains incentive fee that is determined and paid 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 20.0% of the net capital gains as of the end of the fiscal year. In determining the capital gains incentive fee to be paid in cash to the Investment Advisor, the Company calculates the cumulative aggregate realized capital gains and losses since the IPO (realized capital gains and losses include realized gains and losses on investments, net of income tax provision from realized gains on investments, and realized losses on extinguishment of debt), and the aggregate unrealized capital depreciation on investments as of the date of the calculation. At the end of the applicable year, the amount of capital gains that serves as the basis for the calculation of the capital gains incentive fee to be paid equals the cumulative aggregate realized capital gains on investments, less cumulative aggregate realized capital losses on investments, less aggregate unrealized capital depreciation on investments, and less cumulative aggregate realized losses on extinguishment of debt. If this number is positive at the end of such year, then the capital gains incentive fee to be paid in cash for such year equals 20.0% of such amount, less the aggregate amount of any capital gains incentive fees paid in all prior years. We accrue, but do not pay, a capital gains incentive fee in connection with any unrealized capital appreciation, as appropriate.

Examples of Quarterly Incentive Fee Calculation

Example 1: Income Related Portion of Incentive Fee

Alternative 1

Investment income (including interest, dividends, fees, etc.) = 1.25%

(investment income – (management fee + other expenses)) = 0.6125%

Pre-incentive fee net investment income does not exceed hurdle rate, therefore there is no income-related incentive fee.

Alternative 2

Investment income (including interest, dividends, fees, etc.) = 2.9%

(investment income – (management fee + other expenses)) = 2.2625%

Pre-incentive fee net investment income exceeds the hurdle rate, but does not fully satisfy the “catch-up” provision, therefore the income related portion of the incentive fee is 0.2625%.

Alternative 3

Investment income (including interest, dividends, fees, etc.) = 3.5%

(investment income – (management fee + other expenses)) = 2.8625%

Incentive fee = 100% × pre-incentive fee net investment income (subject to “catch-up”)(4)

Incentive fee = 100% × “catch-up” + (20.0% × (pre-incentive fee net investment income – 2.5%))

Pre-incentive fee net investment income exceeds the hurdle rate and fully satisfies the “catch-up” provision, therefore the income related portion of the incentive fee is 0.5725%.

Example 2: Capital Gains Portion of Incentive Fee(*):

Alternative 1

Year 1 : $5.0 million investment made in Company A (“Investment A”), and $7.5 million investment made in Company B (“Investment B”)

Year 2 : Investment A sold for $12.5 million and fair market value (“FMV”) of Investment B determined to be $8.0 million

Year 3 : FMV of Investment B determined to be $6.25 million

Year 4 : Investment B sold for $7.75 million

The capital gains portion of the incentive fee would be:

Year 1 : None

Year 2 : Capital gains incentive fee of $1.5 million — ($7.5 million realized capital gains on sale of Investment A multiplied by 20.0%)

Year 3 : None — $1.25 million (20.0% multiplied by ($7.5 million cumulative capital gains less $1.25 million cumulative capital depreciation)) less $1.5 million (previous capital gains fee paid in Year 2)

Year 4 : Capital gains incentive fee of $50,000 — $1.55 million ($7.75 million cumulative realized capital gains multiplied by 20.0%) less $1.5 million (capital gains incentive fee taken in Year 2)

Alternative 2

Year 1 : $4.0 million investment made in Company A (“Investment A”), $7.5 million investment made in Company B (“Investment B”) and $6.25 million investment made in Company C (“Investment C”)

Year 2 : Investment A sold for $12.5 million, FMV of Investment B determined to be $6.25 million and FMV of Investment C determined to be $6.25 million

Year 3 : FMV of Investment B determined to be $6.75 million and Investment C sold for $7.5 million

Year 4 : FMV of Investment B determined to be $8.75 million

Year 5 : Investment B sold for $5.0 million

The capital gains incentive fee, if any, would be:

Year 1 : None

Year 2 : $1.45 million capital gains incentive fee — 20.0% multiplied by $7.25 million ($8.5 million realized capital gains on Investment A less $1.25 million unrealized capital depreciation on Investment B)

Year 3 : $0.35 million capital gains incentive fee(1) — $1.8 million (20.0% multiplied by $9.0 million ($9.75 million cumulative realized capital gains less $0.75 million unrealized capital depreciation)) less $1.45 million capital gains incentive fee received in Year 2

Year 4 : None

Year 5 : None — $1.45 million (20.0% multiplied by $7.25 million (cumulative realized capital gains of $9.75 million less realized capital losses of $2.5 million)) is less than $1.8 million cumulative capital gains incentive fee paid in Year 2 and Year 3(2)

Payment of Our Expenses

All investment professionals of our investment advisor and/or its affiliates, when and to the extent engaged in providing investment advisory and management services to us, and the compensation and routine overhead expenses of personnel allocable to these services to us, are provided and paid for by our investment advisor and not by us. We bear all other out-of-pocket costs and expenses of our operations and transactions. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Overview – Expenses.”

Duration and Termination

Most recently, at a meeting of our board of directors on June 11, 2025, our board of directors, including a majority of the Independent Directors, unanimously voted to approve the continuation of the Investment Advisory Agreement to June 20, 2026. Unless terminated earlier, the Investment Advisory Agreement will automatically renew for successive annual periods if approved annually by our board of directors or by the affirmative vote of the holders of a majority of our outstanding voting securities (as that term is defined in the 1940 Act), including, in either case, approval by a majority of the Independent Directors.

In reaching a decision to approve the current Investment Advisory Agreement, our board of directors reviewed information comparing our investment performance to other externally managed BDCs with similar investment objectives and to appropriate market indices. The board also reviewed other information and considered, among other things:

Our board of directors did not rank or otherwise assign relative weights to the specific factors it considered in connection with its evaluation of the Investment Advisory Agreement, nor did it undertake to make any specific determination as to whether any particular factor, or any aspect of any particular factor, was favorable or unfavorable to the ultimate decision made by our board of directors. Rather, our board of directors based its approval of the Investment Advisory Agreement on the totality of information presented to it. In considering the factors discussed above, individual directors may have given different weights to different factors.

Based on the information reviewed and the factors discussed above, our board of directors (including the Independent Directors) concluded that the terms of the Investment Advisory Agreement, including the fee rates thereunder, are fair and reasonable in relation to the services provided and approved the continuation of the Investment Advisory Agreement as being in the best interests of FIC and our stockholders.

Conflicts of interest may arise if our investment advisor seeks to change the terms of the Investment Advisory Agreement, including, for example, the amount of the base management fee, the incentive fee or other compensation terms. In general, material amendments to the Investment Advisory Agreement must be approved by the affirmative vote of the holders of a majority of our outstanding voting securities (as that term is defined in the 1940 Act) and by a majority of our Independent Directors.

See “Item 1A. Risk Factors – Risks Relating to our Business and Structure – We are dependent upon our investment advisor’s managing members and our executive officers for our future success. If our investment advisor was to lose any of its managing members or we lose any of our executive officers, our ability to achieve our investment objective could be significantly harmed.”

Indemnification

The Investment Advisory Agreement provides that, absent willful misconduct, bad faith or gross negligence in the performance of its duties under the Investment Advisory Agreement or by reason of the reckless disregard of its duties and obligations under the Investment Advisory Agreement, our investment advisor and its affiliates, and their respective officers, directors, members, managers, partners, stockholders and employees, are entitled to indemnification from us from and against any claims or liabilities, including reasonable legal fees and other expenses reasonably incurred, arising out of or in connection with our investment advisor’s performance of its duties and obligations under the Investment Advisory Agreement or otherwise as our investment advisor.

Administration Agreement

Pursuant to the Administration Agreement, Fidus Investment Advisors, LLC acts as our administrator and furnishes us with office facilities and equipment and clerical, book-keeping and record-keeping services at such facilities. Under the Administration Agreement, our investment advisor performs, or oversees the performance of, our required administrative services, which include being responsible for the financial records that we are required to maintain and preparing reports to our stockholders and reports filed with the SEC. In addition, our investment advisor assists us in determining and publishing our net asset value, overseeing the preparation and filing of our tax returns and the printing and dissemination of reports to our stockholders, and generally overseeing the payment of our expenses and the performance of administrative and professional services rendered to us by others. Under the Administration Agreement, our investment advisor also provides managerial assistance on our behalf to those portfolio companies that have accepted our offer to provide such assistance and we reimburse our Investment Advisor for fees and expenses incurred with providing such services. In addition, we reimburse our Investment Advisor for fees and expenses incurred while performing due diligence on our prospective portfolio companies, including “dead deal” costs for potential investments which are ultimately not pursued. Payments under the Administration Agreement are equal to an amount based upon our allocable portion of our investment advisor’s overhead in performing its obligations under the Administration Agreement, including rent and our allocable portion of the cost of our officers, including our chief financial officer and chief compliance officer and their respective staffs. To the extent that our investment advisor outsources any of its functions, we will pay the fees associated with such functions on a direct basis without profit to our investment advisor.

Most recently, at a meeting of our board of directors on June 11, 2025, our board of directors, including a majority of the Independent Directors, unanimously voted to approve the continuation of the Administration Agreement to June 20, 2026. Unless terminated earlier, the Administration Agreement will automatically renew for successive annual periods if approved annually by our board of directors or by the affirmative vote of the holders of a majority of our outstanding voting securities (as that term is defined in the 1940 Act), including, in either case, approval by a majority of our Independent Directors. In making the decision to approve the continuation of the Administration Agreement, our board of directors took into account, to the extent relevant, certain information set forth above under “Investment Advisory Agreement – Duration and Termination” with respect to its consideration of the Investment Advisory Agreement.

The Administration Agreement may be terminated by either party without penalty upon 60 days’ written notice to the other party. The holders of a majority of our outstanding voting securities (as that term is defined in the 1940 Act) may also terminate the Administration Agreement without penalty.

Indemnification

The Administration Agreement provides that, absent willful misconduct, bad faith or gross negligence in the performance of its duties under the Administration Agreement or by reason of the reckless disregard of its duties and obligations under the Administration Agreement, our investment advisor and its affiliates, and their respective officers, directors, members, managers, stockholders and employees, are entitled to indemnification from us from and against any claims or liabilities, including reasonable legal fees and other expenses reasonably incurred, arising out of or in connection with our investment advisor’s performance of its duties or obligations under the Administration Agreement or otherwise as our administrator.

License Agreement

We have entered into a license agreement with Fidus Partners, LLC under which Fidus Partners, LLC has agreed to grant us a non-exclusive (provided that there is not a change in control of Fidus Partners, LLC), royalty-free license to use the name “Fidus.” Under this agreement, we have a right to use the “Fidus” name for so long as our investment advisor remains our investment advisor. Other than with respect to this limited license, we have no legal right to the “Fidus” name. This license agreement will remain in effect for so long as the Investment Advisory Agreement with our investment advisor remains in effect.

REGULATION

General

We and Fund I have elected to be regulated as BDCs under the 1940 Act and we have elected, and intend to qualify annually, to be treated as a RIC under subchapter M of the Code. The 1940 Act contains prohibitions and restrictions relating to transactions between BDCs and their affiliates (including any investment advisors), principal underwriters and affiliates of those affiliates or principal underwriters and requires that a majority of the directors be persons other than “interested persons,” as that term is defined in the 1940 Act. In addition, the 1940 Act provides that we may not change the nature of our business so as to cease to be, or to withdraw our election as, a BDC unless approved by a majority of our outstanding voting securities, as that term is defined in the 1940 Act.

We may invest up to 100% of our assets in securities acquired directly from issuers in privately negotiated transactions. With respect to such securities, we may, for the purpose of public resale, be deemed an “underwriter” as that term is defined in the Securities Act. Our intention is to not write (sell) or buy put or call options to manage risks associated with any publicly-traded securities that may from time-to-time be held by our portfolio companies, except that we may enter into hedging transactions to manage the risks associated with interest rate fluctuations. However, we may purchase or otherwise receive warrants to purchase the common stock of our portfolio companies in connection with acquisition financing or other investments. Similarly, in connection with an acquisition, we may acquire rights to require the issuers of acquired securities or their affiliates to repurchase them under certain circumstances. We also do not intend to acquire securities issued by any investment company (including Section 3(c)(1) and Section 3(c)(7) funds for this purpose), except for registered money market funds, that exceed the limits imposed by the 1940 Act. Under these limits, we generally cannot acquire more than 3% of the total outstanding voting stock of any investment company, invest more than 5% of the value of our total assets in securities issued by one investment company or invest more than 10% of the value of our total assets in securities issued by investment companies on an aggregate basis. With regard to that portion of our portfolio invested in securities issued by investment companies, it should be noted that such investments might subject our stockholders to additional expenses. These policies are not fundamental and, as a result, each may be changed by the vote of a majority of our board of directors without stockholder approval.

Qualifying Assets

Under the 1940 Act, a BDC may not acquire any asset other than assets of the type listed in section 55(a) of the 1940 Act, which are referred to as “qualifying assets,” unless, at the time the acquisition is made, qualifying assets represent at least 70% of the company’s total assets. The principal categories of qualifying assets relevant to our business are the following:

The regulations defining qualifying assets may change over time. We may adjust our investment focus as needed to comply with and/or take advantage of any regulatory, legislative, administrative or judicial actions in this area.

Managerial Assistance to Portfolio Companies

A BDC must be organized and have its principal place of business in the United States and must be operated for the purpose of making investments in the types of securities described in (a), (b) or (c) above. However, in order to count portfolio securities as qualifying assets for the purpose of the 70% requirement, the BDC must either control the issuer of the securities or must offer to make available to the issuer of the securities significant managerial assistance; except that, when the BDC purchases such securities in conjunction with one or more other persons acting together, one of the other persons in the group may make available such managerial assistance. Making available managerial assistance means, among other things, any arrangement whereby the BDC, through its directors, officers or employees, offers to provide, and, if accepted, does so provide, significant guidance and counsel concerning the management, operations or business objectives and policies of a portfolio company. Our investment advisor, in its capacity as our administrator, has agreed to provide such managerial assistance on our behalf to portfolio companies that request this assistance. We may receive fees for these services and will reimburse our investment advisor, in its capacity as our administrator, for its allocated costs in providing such assistance.

Temporary Investments

Pending investment in other types of qualifying assets, as described above, our investments may consist of cash, cash equivalents, U.S. government securities, repurchase agreements and high-quality debt investments that mature in one year or less from the date of investment, which we refer to, collectively, as temporary investments, so that 70% of our assets are invested in qualifying assets or temporary investments. We may from time to time invest in U.S. Treasury bills or in repurchase agreements, so long as the agreements are fully collateralized by cash or securities issued by the U.S. government, including securities issued by certain U.S. government agencies. A repurchase agreement involves the purchase by an investor, such as us, of a specified security and the simultaneous agreement by the seller to repurchase it at an agreed-upon future date and at a price that is greater than the purchase price by an amount that reflects an agreed-upon interest rate. There is no percentage restriction on the proportion of our assets that may be invested in such repurchase agreements. However, if more than 25% of our total assets constitute repurchase agreements from a single counterparty (other than repurchase agreements fully collateralized by U.S. government securities), we would not satisfy the asset diversification requirements detailed in “Taxation as a RIC,” below. Accordingly, we do not intend to enter into any such repurchase agreements that would cause us to fail such asset diversification requirements. Our investment advisor monitors the creditworthiness of the counterparties with which we enter into repurchase agreement transactions.

Senior Securities

We are permitted, under specified conditions, to issue multiple classes of indebtedness and one class of stock senior to our common stock if our asset coverage, as defined in the 1940 Act, is at least equal to 150% immediately after each such issuance (exclusive of the SBA debentures pursuant to our SEC exemptive relief). In addition, while any senior securities remain outstanding, we must make provisions to prohibit any distribution to our stockholders or the repurchase of such securities or shares unless we meet the applicable asset coverage ratios at the time of the distribution or repurchase. We may also borrow amounts up to 5% of the value of our total assets for temporary or emergency purposes without regard to asset coverage. For a discussion of the risks associated with leverage, see “Risk Factors — Risks Relating to Our Business and Structure — Regulations governing our operation as a BDC affect our ability to raise, and the way in which we raise, additional capital that may have a negative effect on our growth.”

Rule 18f-4 under the 1940 Act relates to the use of derivatives and other transactions that create future payment or delivery obligations by BDCs (and other funds that are registered investment companies). Under Rule 18f-4, BDCs that use derivatives are subject to a value-at-risk leverage limit, certain derivatives risk management program and testing requirements, and requirements related to board reporting. These requirements apply unless the BDC qualifies as a “limited derivatives user,” as defined in Rule 18f-4. A BDC that enters into reverse repurchase agreements or similar financing transactions could either (i) comply with the asset coverage requirements of Section 18, as modified by Section 61 of the 1940 Act, when engaging in reverse repurchase agreements or (ii) choose to treat such agreements as derivative transactions under Rule 18f-4. In addition, under Rule 18f-4, a BDC may enter into an unfunded commitment agreement that is not a derivatives transaction, such as an agreement to provide financing to a portfolio company, if the BDC has a reasonable belief, at the time it enters into such an agreement, that it will have sufficient cash and cash equivalents to meet its obligations with respect to all of its unfunded commitment agreements, in each case as it becomes due. If the BDC cannot meet this requirement, it is required to treat the unfunded commitments as a derivatives transaction subject to the aforementioned requirements of Rule 18f-4.

Codes of Ethics

We, Fund I and our investment advisor have adopted a joint code of ethics pursuant to Rule 17j-1 under the 1940 Act that establishes procedures for personal investments and restricts certain personal securities transactions. Additionally, our investment advisor has adopted a code of ethics pursuant to Rule 204A-1 under the Advisers Act and in accordance with Rule 17j-1(c). Personnel subject to the code of ethics may invest in securities for their personal investment accounts, including securities that may be purchased or held by us, so long as such investments are made in accordance with the code’s requirements. You may read and copy these codes at the SEC’s website at www.sec.gov. The joint code of ethics is also available on our website atwww.fdus.com. We have also adopted a code of business conduct that is applicable to all officers, directors and employees of Fidus and our investment advisor that is available on our website.

Proxy Voting Policies and Procedures

In light of the types of investments held in our portfolio, it is unlikely that we will be called upon to vote our shares very often. In the event that we receive a proxy statement related to one of our portfolio companies, however, we have delegated our proxy voting responsibility to our investment advisor. The proxy voting policies and procedures of our investment advisor are set out below. The guidelines are reviewed periodically by our investment advisor and our Independent Directors, and, accordingly, are subject to change. For purposes of these proxy voting policies and procedures described below, “we,” “our” and “us” refer to our investment advisor.

Introduction

As an investment adviser registered under the Advisers Act, our investment advisor has a fiduciary duty to act solely in our best interests. As part of this duty, our investment advisor recognizes that it must vote our securities in a timely manner free of conflicts of interest and in our best interests.

Our investment advisor’s policies and procedures for voting proxies for its investment advisory clients are intended to comply with Section 206 of, and Rule 206(4)-6 under, the Advisers Act.

Proxy Policies

Our investment advisor will vote proxies relating to our portfolio securities in what it perceives to be the best interest of our stockholders. Our investment advisor reviews on a case-by-case basis each proposal submitted to a stockholder vote to determine its effect on the portfolio securities we hold. In most cases our investment advisor will vote in favor of proposals that it believes are likely to increase the value of the portfolio securities we hold. Although our investment advisor will generally vote against proposals that may have a negative effect on our portfolio securities, our investment advisor may vote for such a proposal if there exist compelling long-term reasons to do so.

Proxy voting decisions are made by our investment advisor’s senior investment professionals who are responsible for monitoring each of our portfolio investments. To ensure that our investment advisor’s vote is not the product of a conflict of interest, our investment advisor requires that (a) anyone involved in the decision-making process disclose to our chief compliance officer any potential conflict that he or she is aware of and any contact that he or she has had with any interested party regarding a proxy vote; and (b) employees involved in the decision-making process or vote administration are prohibited from revealing how our investment advisor intends to vote on a proposal in order to reduce any attempted influence from interested parties. Where conflicts of interest may be present, our investment advisor will disclose such conflicts to us, including our Independent Directors, and may request guidance from us on how to vote such proxies.

Proxy Voting Records

You may obtain information about how our investment advisor voted proxies for us by making a written request for proxy voting information to: Fidus Investment Corporation, 1603 Orrington Avenue, Suite 1005, Evanston, Illinois 60201, Attention: Investor Relations, or by calling Fidus Investment Corporation collect at (847) 859-3940.

Compliance Policies and Procedures

We, Fund I and our investment advisor have each adopted and implemented written policies and procedures reasonably designed to prevent violation of U.S. federal securities laws and are required to review these compliance policies and procedures annually for their adequacy and the effectiveness of their implementation. Our chief compliance officer is responsible for administering these policies and procedures.

Privacy Principles

We are committed to maintaining the privacy of our stockholders and to safeguarding their nonpublic personal information. The following information is provided to help you understand what personal information we collect, how we protect that information and why, in certain cases, we may share information with select other parties.

From time to time, we may receive nonpublic personal information relating to our stockholders. We do not disclose nonpublic personal information about our stockholders or former stockholders to anyone, except as required by law or as is necessary in order to service stockholder accounts (for example, to a transfer agent or third-party administrator).

We restrict access to nonpublic personal information about our stockholders to employees of our investment advisor, its affiliates or authorized service providers that have a legitimate business need for the information. We maintain physical, electronic and procedural safeguards designed to protect the nonpublic personal information of our stockholders.

Other

Under the 1940 Act, we are required to provide and maintain a bond issued by a reputable fidelity insurance company to protect us against larceny and embezzlement. Furthermore, as a BDC, we are prohibited from protecting any director or officer against any liability to us or our stockholders arising from willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of such person’s office.

We may also be prohibited under the 1940 Act from knowingly participating in certain transactions with our affiliates without the prior approval of our Independent Directors and, in some cases, prior approval by the SEC. On June 30, 2014, we received an exemptive order from the SEC to permit us to exclude the senior securities issued by any SBIC subsidiary of the Company, including the SBIC Funds, from the definition of senior securities in the 150% asset coverage requirement applicable to the Company under the 1940 Act.

Small Business Administration Regulations

The SBIC Funds are licensed by the SBA to operate as SBICs under Section 301(c) of the Small Business Investment Act of 1958. Fund III and Fund IV received their SBIC licenses on March 21, 2019 and September 30, 2024, respectively. We may issue SBA debentures to fund additional investments through the SBIC Funds.

SBICs are designed to stimulate the flow of private equity capital to eligible "small businesses" as defined by the SBA. Under SBA regulations, SBICs can provide financing in the form of debt and/or equity securities and provide consulting and advisory services to “eligible” small businesses. The SBIC Funds have typically invested in senior subordinated debt, acquired warrants and/or made other equity investments in qualifying small businesses.

Under current SBA regulations, eligible small businesses generally include businesses that (together with their affiliates) have a tangible net worth not exceeding $24.0 million and have average annual net income after U.S. federal income taxes not exceeding $8.0 million (average net income to be computed without benefit of any carryover loss) for the two most recent fiscal years. In addition, an SBIC must devote 25% of its investment capital to “smaller enterprises” as defined by the SBA. A smaller enterprise generally includes businesses (including their affiliates) that have a net worth not exceeding $6.0 million and have average annual net income after U.S. federal income taxes not exceeding $2.0 million (average net income to be computed without benefit of any net carryover loss) for the two most recent fiscal years. SBA regulations also provide alternative size standard criteria to determine eligibility for designation as an eligible small business or smaller enterprises, which criteria depend on the industry in which the business (including its affiliates) is engaged and are based on the number of employees and gross revenue. However, once an SBIC has invested in a portfolio company, it may continue to make follow-on investments in the portfolio company, regardless of the size of the portfolio company at the time of the follow-on investment, up to the time of the portfolio company’s initial public offering.

The SBA prohibits an SBIC from providing funds to small businesses for certain purposes, such as relending and investments in businesses with the majority of their employees located outside of the U.S. and in businesses engaged in certain prohibited industries, such as project finance, real estate, or certain “passive” (non-operating) companies. In addition, under SBA regulations, without prior SBA approval, an SBIC may not invest more than 30% of its regulatory capital in any one portfolio company or its affiliates (assuming the SBIC intends to draw leverage equal to twice its regulatory capital).

The SBA places certain limitations on the financing terms of investments by SBICs in portfolio companies (such as limiting the permissible interest rate on debt securities held by an SBIC in a portfolio company). SBA regulations allow an SBIC to exercise control over a small business for a period of seven years from the date on which the SBIC initially acquires its control position. This control period may be extended for an additional period of time with the SBA’s prior written approval.

The SBA restricts the ability of an SBIC to lend money to any of its officers, directors and employees or to invest in affiliates thereof. The SBA also prohibits, without prior SBA approval, a “change of control” of an SBIC or transfers that would result in any person (or a group of persons acting in concert) owning 10% or more of a class of capital stock of a licensed SBIC. A “change of control” is any event that would result in the transfer of the power, direct or indirect, to direct the management and policies of an SBIC, whether through ownership, contractual arrangements or otherwise.

An SBIC (or group of SBICs under common control) may generally have outstanding debentures guaranteed by the SBA in amounts up to two times the amount of the regulatory capital of the SBIC(s). Debentures guaranteed by the SBA have a maturity of ten years, require semi-annual payments of interest, and do not require any principal payments prior to maturity. The amount of SBA-guaranteed debentures that affiliated SBIC funds can have outstanding is limited to $350.0 million, subject to SBA approval.

SBICs must invest idle funds that are not being used to make loans in investments permitted under SBA regulations in the following limited types of securities: (i) direct obligations of, or obligations guaranteed as to principal and interest by, the U.S. government, which mature within 15 months from the date of the investment; (ii) repurchase agreements with federally insured institutions with a maturity of seven days or less (and the securities underlying the repurchase obligations must be direct obligations of or guaranteed by the federal government); (iii) certificates of deposit with a maturity of one year or less, issued by a federally insured institution; (iv) a deposit account in a federally insured institution that is subject to a withdrawal restriction of one year or less; (v) a checking account in a federally insured institution; or (vi) a reasonable petty cash fund.

SBICs are periodically examined and audited by the SBA’s staff to determine their compliance with SBA regulations and are periodically required to file certain forms with the SBA.

Neither the SBA nor the U.S. government or any of its agencies or officers has approved any ownership interest to be issued by us or any obligation that we or any of our subsidiaries may incur.

Sarbanes-Oxley Act of 2002

The Sarbanes-Oxley Act of 2002, or the Sarbanes-Oxley Act, imposes a wide variety of regulatory requirements on publicly held companies and their insiders. Many of these requirements affect us. For example:

The Sarbanes-Oxley Act requires us to review our current policies and procedures to determine whether we comply with the Sarbanes-Oxley Act and the regulations promulgated under such act. We will continue to monitor our compliance with all regulations that are adopted under the Sarbanes-Oxley Act and will take actions necessary to ensure that we comply with that act.

The NASDAQ Global Select Market Corporate Governance Regulations

The NASDAQ Global Select Market has adopted corporate governance regulations with which listed companies must comply. We are in compliance with such corporate governance listing standards applicable to BDCs.

Election to Be Taxed as a RIC

We have elected and intend to qualify annually as a RIC for U.S. federal income tax purposes; however, no assurance can be given that we will be able to maintain our RIC tax treatment. To qualify as a RIC, we must, among other things, meet certain source-of-income and asset diversification requirements (as described below). In addition, we generally are required to distribute to our stockholders on a timely basis each year, at least 90% of our “investment company taxable income,” which is our net ordinary income plus the excess, if any, of realized net short-term capital gain over realized net long-term capital loss (the “Annual Distribution Requirement”).

Taxation as a RIC

Provided that we maintain our status as a RIC and satisfy the Annual Distribution Requirement, we will not be subject to U.S. federal income tax on the portion of our investment company taxable income and net capital gain that we timely distribute to stockholders as dividends. We will be subject to U.S. federal income tax imposed at corporate rates on any income or capital gain not distributed (or deemed distributed) to our stockholders.

In addition we will be subject to a nondeductible 4% U.S. federal excise tax on certain undistributed income unless we distribute in a timely manner an amount at least equal to the sum of (i) 98% of our net ordinary income for each calendar year, (ii) 98.2% of the amount by which our capital gain exceeds our capital loss (adjusted for certain ordinary losses) for the one-year period ending October 31 in that calendar year and (iii) certain undistributed amounts from previous years on which we paid no U.S. federal income tax.

In order to maintain our status as a RIC for U.S. federal income tax purposes, we must, among other things:

To the extent that we invest in entities treated as partnerships for U.S. federal income tax purposes (other than a “qualified publicly traded partnership”), we generally must include our allocable share of the items of gross income derived by the partnerships for purposes of the 90% Income Test, and such income generally will be treated as qualifying income for purposes of the 90% Income Test only to the extent that such income would be qualifying income if realized by us directly. In addition, we generally must take into account our proportionate share of the assets held by partnerships (other than a “qualified publicly traded partnership”) in which we are a partner for purposes of the Diversification Tests.

In order to meet the 90% Income Test, we have established several special purpose corporations, and in the future may establish additional corporations, to hold assets from which we do not anticipate earning dividends, interest or other qualifying income under the 90% Income Test (the “Taxable Subsidiaries”). Any investments held through the Taxable Subsidiaries are generally subject to U.S. federal income tax imposed at corporate rates and therefore we can expect to achieve a reduced after-tax yield on such investments.

For U.S. federal income tax purposes, we may be required to recognize taxable income in circumstances in which we do not receive a corresponding payment in cash. For example, if we hold debt instruments that are treated under applicable tax rules as having OID or debt instruments with PIK interest, we must include in income each year a portion of the OID that accrues over the life of the instrument and PIK interest, regardless of whether cash representing such income is received by us in the same taxable year. We may also have to include in income other amounts that we have not yet received in cash, such as deferred loan origination fees that are paid after origination of the loan or are paid in non-cash compensation such as warrants or stock. We anticipate that a portion of our income may constitute OID or other income required to be included in taxable income prior to our receipt of cash.

Because any OID or other amounts accrued will be included in our investment company taxable income for the year of the accrual, we may be required to make a distribution to our stockholders in order to satisfy the Annual Distribution Requirement, even though we will not have received any corresponding cash amount. As a result, we may have difficulty meeting the Annual Distribution Requirement. We may have to sell some of our investments at times and/or at prices we would not consider advantageous, raise additional debt or equity capital or forgo new investment opportunities for this purpose. If we are not able to obtain cash from other sources, we may fail to qualify as a RIC and thus become subject to U.S. federal income tax.

Furthermore, a portfolio company in which we invest may face financial difficulty that requires us to work-out, modify or otherwise restructure our investment in the portfolio company. Any such restructuring may result in unusable capital losses and future non-cash income. Any restructuring may also result in our recognition of a substantial amount of non-qualifying income for purposes of the 90% Income Test, such as cancellation of indebtedness income in connection with the work-out of a leveraged investment (which, while not free from doubt, may be treated as non-qualifying income) or the receipt of other non-qualifying income.

Gain or loss realized by us from warrants acquired by us, as well as any loss attributable to the lapse of such warrants, generally will be treated as capital gain or loss. Such capital gain or loss generally will be long-term or short-term, depending on how long we held a particular warrant.

Investments by us in non-U.S. securities may be subject to non-U.S. income, withholding and other taxes withheld at the source. In this regard, withholding tax rates in countries with which the United States does not have a tax treaty may be 35% or more. The United States has entered into tax treaties with many foreign countries that may entitle us to a reduced rate of tax or exemption from tax on this related income and gains. The effective rate of foreign tax cannot be determined at this time since the amount of our assets to be invested within various countries is not now known. Therefore, our yield on any such securities may be reduced by such non-U.S. taxes. Stockholders will generally not be entitled to claim a credit or deduction with respect to non-U.S. taxes paid by us because we do not expect to satisfy the requirements necessary to pass through to our stockholders their share of the foreign taxes paid by us.

Although we do not presently expect to do so, we are authorized to borrow funds and to sell assets in order to satisfy the Annual Distribution Requirement and to avoid imposition of the 4% U.S. federal excise tax. However, under the 1940 Act, we are not permitted to make distributions to our stockholders while our debt obligations and other senior securities are outstanding unless certain “asset coverage” tests are met. See “Regulation — Qualifying Assets” and “Regulation — Senior Securities.” If we are prohibited from making distributions, we may fail to qualify for tax treatment as a RIC and become subject to U.S. federal income tax. Moreover, our ability to dispose of assets to satisfy the Annual Distribution Requirement and to avoid imposition of the 4% U.S. federal excise tax may be limited by (1) the illiquid nature of our portfolio and/or (2) other requirements relating to our status as a RIC, including the Diversification Tests. If we dispose of assets in order to meet the Annual Distribution Requirement or to avoid imposition of the 4% U.S. federal excise tax, we may make such dispositions at times that, from an investment standpoint, are not advantageous.

As a RIC, we are generally limited in our ability to deduct expenses in excess of our “investment company taxable income” (which is generally, ordinary income plus the excess of net short-term capital gains over net long-term capital losses). If our expenses in a given year exceed investment company taxable income, we would experience a net operating loss for that year. However, a RIC is not permitted to carry forward net operating losses to subsequent years. In addition, expenses can be used only to offset investment company taxable income, not net capital gain. A RIC may not use any net capital losses (that is, realized capital losses in excess of realized capital gains) to offset the RIC’s investment company taxable income, but may carry forward such losses indefinitely and use them to offset capital gains. Due to these limits on the deductibility of expenses, over the course of one or more taxable years we may have, for U.S. federal income tax purposes, aggregate taxable income that we are required to distribute and that is taxable to our shareholders, even if such income is greater than the aggregate net income we actually earned during those years. Such required distributions may be made from our cash assets or by liquidation of investments, if necessary. We may realize gains or losses from such liquidations. In the event we realize net capital gains from such transactions, a shareholder may receive a larger capital gain distribution than we would have received in the absence of such transactions.

Certain of our investment practices may be subject to special and complex U.S. federal income tax provisions that may, among other things, (i) disallow, suspend or otherwise limit the allowance of certain losses or deductions, (ii) convert lower taxed long-term capital gain and qualified dividend income into higher taxed short-term capital gain or ordinary income, (iii) convert an ordinary loss or a deduction into a capital loss (the deductibility of which is more limited), (iv) cause us to recognize income or gain without a corresponding receipt of cash, (v) adversely affect the time as to when a purchase or sale of stock or securities is deemed to occur, (vi) adversely alter the characterization of certain complex financial transactions, and (vii) produce income that will not be qualifying income for purposes of the 90% Income Test. We will monitor our transactions and may make certain tax elections in order to mitigate the effect of these provisions.

As described above, to the extent that we invest in equity securities of entities that are treated as partnerships for U.S. federal income tax purposes, the effect of such investments for purposes of the 90% Income Test and the Diversification Tests will depend on whether or not the partnership is a “qualified publicly traded partnership” (as defined in the Code). If the partnership is a “qualified publicly traded partnership,” the net income derived from such investments will be qualifying income for purposes of the 90% Income Test and will be “securities” for purposes of the Diversification Tests. If the partnership, however, is not treated as a “qualified publicly traded partnership,” then the consequences of an investment in the partnership will depend upon the amount and type of income and assets of the partnership allocable to us. The income derived from such investments may not be qualifying income for purposes of the 90% Income Test and, therefore, could adversely affect our tax treatment as a RIC. We intend to monitor our investments in equity securities of entities that are treated as partnerships for U.S. federal income tax purposes in an effort to prevent our disqualification as a RIC.

We may invest in preferred securities or other securities the U.S. federal income tax treatment of which may not be clear or may be subject to recharacterization by the Internal Revenue Service (“IRS”). To the extent the tax treatment of such securities or the income from such securities differs from the expected tax treatment, it could affect the timing or character of income recognized, requiring us to purchase or sell securities, or otherwise change our portfolio, in order to comply with the tax rules applicable to RICs.

We may make distributions that are payable in cash or shares of our stock at the election of each stockholder. In accordance with Treasury regulations and published guidance issued by the Internal Revenue Service, a publicly offered RIC may treat distributions of its own stock as counting towards its RIC distribution requirements if each stockholder may elect to receive his, her, or its entire distribution in either cash or stock of the RIC, subject to a limitation that the aggregate amount of cash to be distributed to all stockholders must be at least 20% of the aggregate distribution. If too many stockholders elect to receive their distributions in cash, the cash available for distribution must be allocated among the shareholders electing to receive cash (with the balance of the distribution paid in stock). If we qualify as a publicly offered RIC and decide to make any distributions that are payable in part in shares of our stock, U.S. stockholders receiving such distributions will be required to include the full amount of the distribution (whether received in cash, shares of our stock, or a combination thereof) as ordinary income (or as long-term capital gain to the extent such distribution is properly reported as a capital gain dividend) to the extent of our current and accumulated earnings and profits. As a result, a U.S. stockholder may be required to pay tax with respect to such distributions in excess of any cash received. If a U.S. stockholder sells the stock it receives in order to pay this tax, the sales proceeds may be less than the amount included in income with respect to the distribution, depending on the market price of our stock at the time of the sale. Furthermore, with respect to non-U.S. stockholders, we may be required to withhold U.S. federal tax with respect to such distributions, including in respect of all or a portion of such distributions that are payable in stock. In addition, if a significant number of our stockholders determine to sell shares of our stock in order to pay taxes owed on such distributions, it may put downward pressure on the trading price of shares of our stock.

We may decide to retain some or all of our long-term capital gains in excess of the amount required to satisfy the Annual Distribution Requirement, but designate the retained amount as a “deemed distribution.” In that case, among other consequences, we will pay tax on the retained amount on behalf of the stockholders. Each U.S. stockholder will be required to include his, her or its share of the deemed distribution in income as if it had been actually distributed to the U.S. stockholder, and the stockholder will be entitled to claim a credit equal to his, her or its allocable share of the tax paid thereon by us. Since non-U.S. stockholders generally would not have U.S. tax liability with respect to the deemed capital gain distribution, they would not be entitled to credit the tax paid by us for U.S. tax purposes. Whether non-U.S. stockholders could claim a credit with respect to their non-U.S. tax liability will depend on the foreign tax credit rules of the country in which they are a resident. In order to utilize the deemed distribution approach, we must provide written notice to our stockholders prior to the expiration of 60 days after the close of the relevant taxable year. We cannot treat any of our investment company taxable income as a “deemed distribution.”

Failure to Obtain RIC Tax Treatment

If we were unable to maintain our tax treatment as a RIC, and certain relief provisions are unable to be satisfied (which may, among other things, require us to pay U.S. federal income tax or to dispose of certain assets), we would be subject to U.S. federal income tax (and any applicable state and local taxes) on all of our taxable income imposed at corporate rates, on all of our taxable income (including our net capital gains), regardless of whether we make any distributions to our stockholders. In any taxable year that we do not qualify as a RIC, distributions would not be required, but if such distributions are paid, including distributions of net long-term capital gain, they would be taxable to our stockholders as ordinary dividend income to the extent of our current and accumulated earnings and profits. Subject to certain holding period requirements and other limitations under the Code, corporate stockholders would be eligible to claim a dividends received deduction with respect to such dividend and non-corporate stockholders would generally be able to treat such dividend income as “qualified dividend income,” which is subject to reduced rates of U.S. federal income tax. Distributions in excess of our current and accumulated earnings and profits would be treated first as a return of capital to the extent of the stockholder’s adjusted tax basis, and any remaining distributions would be treated as a capital gain.

In order to requalify as a RIC, in addition to the other requirements discussed above, we would be required to satisfy the RIC qualification requirements for that year and distribute all of our previously undistributed earnings attributable to the period we failed to qualify as a RIC by the end of the first year that we intend to requalify as a RIC. If we fail to qualify as a RIC for a period greater than two taxable years, to requalify as a RIC in a subsequent year we may be subject to U.S. federal income tax imposed at corporate rates on any net built-in gains with respect to certain of our assets (i.e. the excess of the aggregate gains, including items of income, over aggregate losses that would have been realized with respect to such assets if we had been liquidated) that we elect to recognize on requalification or when recognized over the next five years.
