If you vote by mail, Internet or telephone as described in the instructions on the proxy card or voting instruction form, and we receive your vote in time for the Annual Meeting, the persons named as proxies will vote the shares registered directly in your name in the manner that you specified. If you give no instructions on the proxy card, the shares covered by the proxy card will be voted FOR the election of the director nominees and FOR the other matters listed in the accompanying Notice of Annual Meeting of Stockholders.

INFORMATION ABOUT THE MEETING

When is the Annual Meeting?

The Annual Meeting will be held on Wednesday, June 12, 2024, at 8:30 a.m. (Central Time).

Where will the Annual Meeting be held?

The Annual Meeting will be held at 1603 Orrington Avenue, Suite 1005, Evanston, Illinois, 60201.

What items will be voted on at the Annual Meeting?

There are two matters scheduled for a vote:

1. To elect two Class I directors to serve until the 2027 annual meeting of stockholders or their respective successor has been duly elected and qualified (Proposal No. 1); and

2. To approve a proposal to authorize the Company, subject to the approval of the Company’s Board of Directors, to sell or otherwise issue shares of its common stock during the next year at a price below the Company’s then current net asset value (“NAV”) per share, subject to certain conditions as set forth in this proxy statement (including that the cumulative number of shares sold pursuant to such authority does not exceed 25% of its then outstanding common stock immediately prior to each such sale) (Proposal No. 2).

As of the date of this proxy statement, we are not aware of any other matters that will be presented for consideration at the Annual Meeting. Shareholders have no dissenters’ or appraisal rights in connection with any of the proposals described herein.

What are the Board of Directors’ recommendations?

Our Board of Directors recommends that you vote:

“FOR” the election of the two Class I director nominees named herein to serve on the Board of Directors; and

“FOR” the proposal to authorize the Company, subject to the approval of the Company’s Board of Directors, to sell or otherwise issue shares of its common stock during the next year at a price below the Company’s then current NAV per share, subject to certain conditions as set forth in this proxy statement (including that the cumulative number of shares sold pursuant to such authority does not exceed 25% of its then outstanding common stock immediately prior to each such sale).

Will Fidus’ directors be in attendance at the Annual Meeting?

Fidus encourages, but does not require, its directors to attend annual meetings of stockholders. However, Fidus anticipates that all of its directors will attend the Annual Meeting.

INFORMATION ABOUT VOTING

Who is entitled to vote at the Annual Meeting?

Only stockholders of record at the close of business on the record date, March 21, 2024, are entitled to receive notice of the Annual Meeting and to vote the shares for which they were stockholders of record on that date at the Annual Meeting, or any postponement or adjournment of the Annual Meeting. As of the close of business on March 21, 2024, we had [●] shares of common stock outstanding.

How do I vote?

With respect to Proposal No. 1, you may either vote “FOR” each Class I nominee to the Board of Directors, or you may vote “WITHHOLD AUTHORITY” for each nominee. For Proposal No. 2, you may vote “FOR” or “AGAINST,” or abstain from voting altogether. The procedures for voting are fairly simple:

Stockholders of Record: Shares Registered in Your Name. If on March 21, 2024, your shares were registered directly in your name with Fidus’ transfer agent, American Stock Transfer & Trust Company, LLC, then you are a stockholder of record. If you are a stockholder of record, you may vote in person at the Annual Meeting or vote by giving us your proxy. You may give us your proxy by completing the enclosed proxy card and returning it in the enclosed postage-prepaid envelope, or by calling a toll-free telephone number or using the Internet as further described below and on the enclosed proxy card. Whether or not you plan to attend the Annual Meeting, we urge you to sign and return the enclosed proxy card or to otherwise give your proxy authorization by telephone or Internet, as specified on the proxy card, to ensure your vote is counted. You may still attend the Annual Meeting and vote in person if you have already signed and returned your proxy card.

Beneficial Owners: Shares Registered in the Name of a Broker or Bank. If on March 21, 2024, your shares were held in an account at a brokerage firm, bank, dealer or other similar organization, then you are the beneficial owner of shares held in “street name,” and these proxy materials are being forwarded to you by that organization. If you are a beneficial owner of shares registered in the name of your broker, bank or other agent, you should have received from that organization rather than from Fidus, a proxy card and voting instructions with these proxy materials. Simply complete and mail the proxy card to ensure that your vote is counted. Alternatively, you may be able to vote by telephone or over the Internet if permitted by your broker or bank. To vote in person at the Annual Meeting, you must obtain a valid proxy from your broker, bank or other agent. Follow the voting instruction form from your broker or bank included with these proxy materials, or contact your broker or bank to request a proxy card.

3

How many votes do I have?

On each matter to be voted upon, you have one vote for each share of common stock for which you were the stockholder of record as of March 21, 2024.

What does it mean if I receive more than one proxy card?

If you receive more than one proxy card, your shares are registered in more than one name or are registered in different accounts. Please provide a response (by telephone, Internet or mail as provided for on the proxy card accompanying this proxy statement or on the voting instruction form from your broker or bank) for each proxy card you receive to ensure that all of your shares are voted.

What if I return a proxy card but do not make specific choices?

If you return a signed and dated proxy card without marking any voting selections, your shares will be voted in accordance with the recommendation of the Board of Directors: “FOR” the election of each nominee named herein to serve as a Class I director on the Board of Directors and “FOR” the proposal to authorize the Company, subject to the approval of the Company’s Board of Directors, to sell or otherwise issue shares of its common stock during the next year at a price below the Company’s then current NAV per share, subject to certain conditions as set forth in this proxy statement (including that the cumulative number of shares sold pursuant to such authority does not exceed 25% of its then outstanding common stock immediately prior to each such sale).

If any other matter is properly presented at the Annual Meeting, your proxy (one of the individuals named on your proxy card) will vote your shares as recommended by the Board of Directors or, if no recommendation is given, will vote your shares using his or her discretion.

Can I change my vote after submitting my proxy card?

Yes. You can revoke your proxy at any time before the final vote at the Annual Meeting. If you are the stockholder of record of your shares, you may revoke your proxy in any one of three ways:

If your shares are held by your broker or bank as a nominee or agent, you should follow the instructions on the voting instruction form provided by your broker or bank.

How are votes counted?

Votes will be counted by the inspector of election appointed for the Annual Meeting, who will separately count each vote marked “FOR” or “WITHHOLD AUTHORITY” for each nominee for Class I director identified in Proposal No. 1 and, with respect to Proposal No. 2, will separately count each vote marked “FOR,” “AGAINST” or “ABSTAIN.” Abstentions and broker non-votes will be deemed to be present for the purpose of determining a quorum for the Annual Meeting. However, abstentions and broker non-votes are not counted as votes cast. A “broker non-vote” with respect to a matter occurs when a broker, bank or other institution or nominee holding shares on behalf of a beneficial owner has not received voting instructions from the beneficial

4

owner on a particular proposal and does not have, or chooses not to exercise, discretionary authority to vote the shares on such proposals. Notwithstanding the foregoing, the Company will not have any broker non-votes at the Annual Meeting because there are only non-routine proposals to be voted on at the Annual Meeting.

How many votes are needed to approve each proposal?

How many shares must be present to constitute a quorum for the Annual Meeting?

A quorum of stockholders is necessary to hold a valid meeting. A quorum will be present if at least a simple majority (i.e., greater than 50%) of the outstanding shares entitled to vote are represented at the Annual Meeting either in person or by proxy. On March 21, 2024, the record date, there were [●] shares outstanding and entitled to vote. Thus [●] shares must be represented at the Annual Meeting either in person or by proxy to constitute a quorum.

Your shares will be counted towards the quorum only if you submit a valid proxy by mail, Internet or telephone (or one is submitted on your behalf by your broker, bank or other nominee) or if you vote in person at the Annual Meeting. Abstentions will be counted towards the quorum requirement.

If a quorum is not present at the Annual Meeting, or if a quorum is present but there are not enough votes to approve one or more of the proposals, the person named as chairman of the Annual Meeting may adjourn the meeting to permit further solicitation of proxies. A stockholder vote may be taken on one or more of the proposals in this proxy statement prior to any such adjournment if there are sufficient votes for approval on such proposal(s).

How can I find out the results of the voting at the Annual Meeting?

Preliminary voting results will be announced at the Annual Meeting and filed on Form 8-K within four business days of the Annual Meeting. Final results, if different from the preliminary results, will be published on an amended Form 8-K within four days after the final voting results are established.

ADDITIONAL INFORMATION

How and when may I submit a stockholder proposal for Fidus’ 2025 Annual Meeting?

We will consider for inclusion in our proxy materials for the 2025 Annual Meeting of Stockholders, stockholder proposals that are received at our executive offices, in writing, no earlier than [●], 2024 and no later than 5:00 p.m. (Eastern Time) on [●], 2024, and that comply with our bylaws and all applicable requirements of Rule 14a-8 promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Proposals must be sent to our Corporate Secretary at Fidus Investment Corporation, 1603 Orrington Avenue, Suite 1005, Evanston, Illinois 60201.

Pursuant to our bylaws, stockholders wishing to nominate persons for election as directors or to introduce an item of business at an annual meeting that are not to be included in our proxy materials must have given timely notice thereof in writing to our Corporate Secretary. To be timely for the 2025 Annual Meeting of Stockholders, you must notify our Corporate Secretary, in writing, no earlier than [●], 2024, and no later than 5:00 p.m. (Eastern Time) on [●], 2024. We also advise you to review our bylaws, which contain additional requirements about advance notice of stockholder proposals and director nominations, including the different notice submission date requirements in the event that our 2025 Annual Meeting of Stockholders is held more than 30 days before or after the first anniversary of the date the notice for the 2024 annual meeting is mailed. In accordance with our bylaws, the chairman of the 2025 Annual Meeting of Stockholders may determine, if the facts warrant, that a matter has not been properly brought before the meeting and, therefore, may not be considered at the meeting.

Pursuant to the Company’s bylaws, among other things, a stockholder’s notice shall set forth as to each individual whom the stockholder proposes to nominate for election or reelection as a director:

The above procedures summarize the stockholder nomination procedures contained in our bylaws, and any stockholder desiring to submit a nominee should consult our bylaws regarding these requirements.

All nominees properly submitted to the Company (or which the nominating and corporate governance committee (“Nominating Committee”) otherwise elects to consider) will be evaluated and considered by the members of the Nominating Committee using the same criteria as nominees identified by the Nominating Committee itself.

How can I obtain the Company’s Annual Report on Form 10-K?

A copy of our Annual Report on Form 10-K for the fiscal year ended December 31, 2023 is being mailed with this proxy statement. Our Annual Report is not incorporated into this proxy statement and shall not be considered proxy solicitation material.

6

We will also mail to you, without charge and upon your written request, a copy of any specifically requested exhibit to our Annual Report on Form 10-K for the fiscal year ended December 31, 2023.

Requests should be sent to: Corporate Secretary, Fidus Investment Corporation, 1603 Orrington Avenue, Suite 1005, Evanston, Illinois 60201. A copy of our Annual Report on Form 10-K has also been filed with the Securities and Exchange Commission, or the SEC, and may be accessed from the SEC’s homepage (http://www.sec.gov).

Who is paying for this proxy solicitation?

Fidus will pay for the entire cost of soliciting proxies. We estimate that we will pay Alliance Advisors, LLC, our proxy solicitor, a fee of approximately $300,000, plus reimbursement for out of pocket expenses, to solicit proxies, though the costs of this proxy solicitation process could be lower or higher than our estimate. In addition to these written proxy materials, our proxy solicitor, directors, officers and employees of Fidus Investment Advisors, LLC, the Company’s investment adviser and administrator (our “Investment Advisor”), may also solicit proxies in person, by telephone or by other means of communication; however, our directors, officers and employees of our Investment Advisor will not be paid any additional compensation for soliciting proxies. In addition to the solicitation of proxies by the use of the mail, proxies may be solicited in person and/or by telephone or facsimile transmission by our proxy solicitor, directors, officers or employees of our Investment Advisor. Our Investment Advisor is located at 1603 Orrington Avenue, Suite 1005, Evanston, Illinois 60201.

We may also reimburse brokerage firms, banks and other agents for the cost of forwarding proxy materials to beneficial owners and obtaining your voting instructions.

How many copies should I receive if I share an address with another stockholder?

The SEC has adopted rules that permit companies and intermediaries, such as brokers, to satisfy the delivery requirements for proxy statements and annual reports with respect to two or more stockholders sharing the same address by delivering a single proxy statement addressed to those stockholders. This process, which is commonly referred to as “householding,” potentially provides extra convenience for stockholders and cost savings for companies.

Brokers may be householding our proxy materials by delivering a single proxy statement and Annual Report to multiple stockholders sharing an address unless contrary instructions have been received from the affected stockholders. Once you have received notice from your broker that they will be householding materials to your address, householding will continue until you are notified otherwise or until you revoke your consent. If you did not respond that you did not want to participate in householding, you were deemed to have consented to the process. If at any time you no longer wish to participate in householding and would prefer to receive a separate proxy statement and Annual Report, or if you are receiving multiple copies of the proxy statement and Annual Report and wish to receive only one, please notify your broker if your shares are held in a brokerage account or us if you are a stockholder of record. You can notify us by sending a written request to: Shelby E. Sherard, Corporate Secretary, Fidus Investment Corporation, 1603 Orrington Avenue, Suite 1005, Evanston, Illinois 60201, or by calling (847) 859-3940. In addition, Fidus will promptly deliver, upon written or oral request to the address or telephone number above, a separate copy of the Annual Report and proxy statement to a stockholder at a shared address to which a single copy of the documents was delivered.

Whom should I contact if I have any questions?

If you have any questions about the Annual Meeting, these proxy materials or your ownership of our common stock, please contact Shelby E. Sherard c/o Fidus Investment Corporation, 1603 Orrington Avenue, Suite 1005, Evanston, Illinois 60201, Telephone (847) 859-3940, or Fax: (847) 859-3953.

PROPOSAL NO. 1

ELECTION OF CLASS I DIRECTORS

Our Board of Directors is divided into three classes. Each class has a three-year term. Each director holds office for the term to which he or she is elected and until his or her successor is duly elected and qualified. Vacancies on the Board of Directors may be filled by persons elected by a majority of the remaining directors. A director elected by the Board of Directors to fill a vacancy in a class, including any vacancies created by an increase in the number of directors, shall serve for the remainder of the full term of that class or until the director’s successor is duly elected and qualified.

The Board of Directors has six members. There are two members of the class of directors whose term expires in 2024 (Class I), Mr. Hyman and Ms. Corley. If elected at the Annual Meeting, each nominee will serve until the 2027 Annual Meeting of Stockholders or until his or her respective successor is elected and qualified or, if sooner, until his or her death, resignation or removal. Mr. Hyman and Ms. Corley are not being nominated for election, nor has any director, executive officer or other listed officer of the Company been selected as a director, executive officer or other officer pursuant to any agreement or understanding with the Company or any other person. Mr. Hyman and Ms. Corley have indicated their willingness to continue to serve if elected and have consented to be named as nominees. Mr. Hyman and Ms. Corley are not “interested persons” of the Company as defined in Section 2(a)(19) of the 1940 Act.

A stockholder can vote for or withhold his or her vote for each nominee. In the absence of instructions to the contrary, it is the intention of the persons named as proxies to vote each such proxy for the election of the nominees named below in accordance with the recommendation of the Board of Directors. If either of the nominees should decline or be unable to serve as a director, it is intended that the proxy will be voted for the election of such person(s) who is nominated as a replacement. The Board of Directors has no reason to believe that the Class I director nominees named will be unable or unwilling to serve.

Certain of our directors who are also officers of the Company may serve as directors of, or on the boards of managers of, certain of our portfolio companies. In addition, the Board of Directors of Fidus Mezzanine Capital, L.P., or Fund I, a wholly-owned consolidated subsidiary that has elected to be treated as a business development company (“BDC”) under the 1940 Act, is composed of all of the Company’s directors.

The business address of each nominee and director listed below is 1603 Orrington Avenue, Suite 1005, Evanston, Illinois 60201.

Qualifications of Directors

When considering whether our director nominees have the experience, qualifications, attributes and skills, taken as a whole, to enable our Board of Directors to satisfy its oversight responsibilities effectively in light of our operational and organizational structure, the Nominating Committee and the Board of Directors focused

11

primarily on the information discussed in each of the director nominee’s individual biographies set forth above and on the following particular attributes:

Interested Directors

Independent Directors

12

INFORMATION ABOUT EXECUTIVE OFFICER WHO IS NOT A DIRECTOR

The following is a brief biography of our executive officer, Shelby E. Sherard, who is not a director of the Company.

13

CORPORATE GOVERNANCE

Director Independence

The Board of Directors has a majority of directors who are independent under the listing standards of the Nasdaq Global Select Market, or Nasdaq. The Nasdaq Stock Market Rules provide that a director of a BDC shall be considered to be independent if he or she is not an “interested person” of the Company, as defined in Section 2(a)(19) of the 1940 Act. Section 2(a)(19) of the 1940 Act defines an “interested person” to include, among other things, any person who has, or within the last two years had, a material business or professional relationship with the Company.

The Board of Directors has determined that the following directors are independent: Messrs. Anstiss, Hyman and Tune and Ms. Corley. Messrs. Ross and Lauer are “interested persons” due to their positions with the Company and/or our Investment Advisor, as discussed in their respective biographies. Based upon information requested and received from each director concerning their respective background, employment and affiliations, the Board of Directors has affirmatively determined that none of the independent directors has a material business or professional relationship with the Company, other than in his capacity as a member of the Board of Directors or any committee thereof.

Meetings of the Board and Committees of the Board

The Board of Directors has established the Audit Committee and Nominating Committee. The Company does not have a separate compensation committee because its executive officers do not receive any direct compensation from the Company; however, the Audit Committee has been charged with carrying out the duties that would typically be addressed by a compensation committee. During 2023, the Board of Directors held seven meetings, the Audit Committee held nine meetings and the Nominating Committee held two meetings. The Company encourages, but does not require, the directors to attend the Company’s annual meeting of its stockholders. During 2023, all of our directors attended 100% of the aggregate number of meetings of the Board of Directors and the respective committees on which they served. All of our directors attended the 2023 annual meeting of stockholders.

Board Leadership Structure

The Board of Directors monitors and performs an oversight role with respect to the business and affairs of the Company. Among other things, the Board of Directors approves the appointment of our Investment Advisor, administrator and officers, reviews and monitors the services and activities performed by our Investment Advisor, administrator and officers, approves annually the renewal of any investment advisory agreement with our Investment Advisor and approves the engagement, and reviews the performance of, the Company’s independent registered public accounting firm.

Under the bylaws, the Board of Directors may designate a chairman to preside over the meetings of the Board of Directors and meetings of the stockholders and to perform such other duties as may be assigned to him by the Board of Directors. The Company does not have a fixed policy as to whether the chairman of the Board of Directors should be an independent director and believes that its flexibility to select its chairman and reorganize its leadership structure from time to time is in the best interests of the Company and its stockholders.

Presently, Mr. Ross serves as the chairman of the Board of Directors. Mr. Ross is an interested director because he is the Chief Executive Officer of the Company, serves on our Investment Advisor’s investment committee and is a manager of our Investment Advisor. The Company believes that Mr. Ross’s history with the Company, familiarity with the Fidus investment platform and extensive experience in the management of private equity and debt investments qualifies him to serve as chairman of the Board of Directors. Moreover, our Board of Directors believes that it is in the best interests of our stockholders for Mr. Ross to lead our Board of Directors because of his broad experience with the day-to-day management and operation of other investment funds and his significant background in the financial services industry, as described above.

14

Our Board of Directors does not have a lead independent director. We are aware of the potential conflicts that may arise when a non-independent director is Chairman of the Board, but believe these potential conflicts are offset by our strong corporate governance practices. Our corporate governance practices include regular meetings of the independent directors in executive session without the presence of interested directors and management, the establishment of an Audit and Compensation Committee and a Nominating and Corporate Governance Committee, each of which is comprised solely of independent directors, and the appointment of a Chief Compliance Officer, with whom the independent directors meet without the presence of interested directors and other members of management, for administering our compliance policies and procedures. Additionally, Mr. Anstiss, an independent director and the chairman of the Audit Committee, acts as a liaison between the independent directors and management between meetings of our Board of Directors and presides over regular executive sessions of the Board of Directors. Our Board of Directors believes that its leadership structure is appropriate in light of the Company’s characteristics and circumstances because the structure allocates areas of responsibility among the individual directors and the committees in a manner that encourages effective oversight. Specifically, the Board of Directors believes that the relationship of Messrs. Ross and Lauer with our Investment Advisor provides an effective bridge between the Board and management, and encourages an open dialogue between management and our Board, ensuring that these groups act with a common purpose. The members of our Board of Directors also believe that its small size creates a highly efficient governance structure that provides ample opportunity for direct communication and interaction between both the members of management and our Investment Advisor and our Board of Directors.

Board Role in Risk Oversight

The Board of Directors performs its risk oversight function primarily through (a) its two standing committees, which report to the entire Board of Directors and are comprised solely of independent directors and (b) monitoring by the Company’s Chief Compliance Officer in accordance with its compliance policies and procedures.

As described below in more detail under “Audit and Compensation Committee” and “Nominating and Corporate Governance Committee,” the Audit Committee and the Nominating Committee assist the Board of Directors in fulfilling its risk oversight responsibilities. The Audit Committee’s risk oversight responsibilities include overseeing the Company’s accounting and financial reporting processes, the Company’s systems of internal controls regarding finance and accounting and audits of the Company’s financial statements and discussing with management the Company’s major financial risk exposures and the steps management has taken to monitor and control such exposures, including the Company’s risk assessment and risk management policies. The Nominating Committee’s risk oversight responsibilities include selecting, researching and nominating directors for election by the Company’s stockholders, developing and recommending to the Board of Directors a set of corporate governance principles and overseeing the evaluation of the Board of Directors and its committees. Both the Audit Committee and the Nominating Committee consist solely of independent directors.

The Board of Directors is assisted in its risk oversight responsibilities by the Chief Compliance Officer. The Company’s Chief Compliance Officer prepares a written report annually discussing the adequacy and effectiveness of the compliance policies and procedures of the Company and certain of its service providers. The Chief Compliance Officer’s report, which is reviewed by the Board of Directors, addresses at a minimum (a) the operation of the compliance policies and procedures of the Company and certain of its service providers since the last report; (b) any material changes to such policies and procedures since the last report; (c) any recommendations for material changes to such policies and procedures as a result of the Chief Compliance Officer’s annual review; and (d) any compliance matter that has occurred since the date of the last report about which the Board of Directors would reasonably need to know to oversee the Company’s compliance activities and risks. In addition, the Chief Compliance Officer meets separately in executive session with the independent directors periodically, but in no event less than once each year.

The Company believes that the Board of Directors’ role in risk oversight is effective and appropriate given the extensive regulation to which it is already subject as a BDC. Specifically, as a BDC, the Company must

15

comply with certain regulatory requirements that control the levels of risk in its business and operations. For example, the Company’s ability to incur indebtedness is limited such that its asset coverage must equal at least 150% immediately after each time it incurs indebtedness and the Company generally has to invest at least 70% of its total assets in “qualifying assets” as described in section 55 of the 1940 Act. In addition, the Company has elected, and intends to qualify annually, to be treated as a regulated investment company, or RIC, under Subchapter M of the Internal Revenue Code of 1986, as amended. As a RIC, the Company must, among other things, meet certain source-of-income and asset diversification requirements.

The Company believes that the Board of Directors’ existing role in risk oversight is appropriate. However, the Company re-examines the manner in which the Board of Directors administers its oversight function on an ongoing basis to ensure that it continues to meet the Company’s needs.

Audit and Compensation Committee

The members of the Audit Committee are Messrs. Anstiss, Hyman and Tune and Ms. Corley, each of whom is not an interested person and is otherwise independent for purposes of the 1940 Act and Nasdaq’s corporate governance regulations. Since September 2011, Mr. Anstiss has served as chairman of the Audit Committee. Our board of directors has adopted a charter for the Audit Committee, which is available on our website at https://investor.fdus.com/corporate-governance

The Audit Committee is responsible for approving our independent accountants and recommending them to the Board of Directors (including a majority of the independent directors) for approval and submission to the Board of Directors for ratification, reviewing with our independent accountants the plans and results of the audit engagement, approving professional services provided by our accountants, reviewing the independence of our independent accountants and reviewing the adequacy of our internal accounting controls.

The Audit Committee is also responsible for aiding the Board of Directors in determining the fair value of debt and equity securities that are not publicly traded or for which current market values are not readily available. The Audit Committee also currently receives input from independent valuation firms that have been engaged at the direction of the Board of Directors to value certain portfolio investments. In addition, the Audit Committee is responsible for discussing with management our major financial risk exposures and the steps management has taken to monitor and control such exposures, including our risk assessment and risk management policies.

The Board of Directors has determined that Mr. Anstiss is an “audit committee financial expert” as defined in Item 407 of Regulation S-K. Mr. Anstiss acquired his financial expertise from his education experience as a public accountant, his experience actively supervising financial officers of public companies and in his supervisory role at a public accounting firm and from his experience overseeing and assessing the performance of public accountants with respect to the preparation, auditing and evaluation of financial statements. Mr. Anstiss has consented to be named as an audit committee financial expert in this proxy statement.

Because the Audit Committee is charged with approving our related-party transactions, the board of directors has determined not to create a separate compensation committee and instead has charged the Audit Committee with overseeing amounts payable to our Investment Advisor pursuant to the Advisory Agreement and the Administration Agreement, and making a recommendation to the Board of Directors with respect to the Board’s approval (including the approval of a majority of the directors who are not “interested persons” of the Company within the meaning of Section 2(a)(19) of the 1940 Act, as amended) of the renewal of the Advisory Agreement and the Administration Agreement.

The Board of Directors has determined not to create a separate compensation committee charter and instead has included applicable compensation charter provisions in the charter of the Audit Committee, which is available on our website at https://investor.fdus.com/corporate-governance. The Audit Committee charter sets forth the responsibilities of a compensation committee, including overseeing the Company’s compensation

16

policies, evaluating executive officer performance and reviewing and approving the compensation, if any, by the Company of its executive officers.

In reviewing and approving the compensation, if any, by the Company for each of the Company’s executive officers, the Audit Committee will, among other things, consider corporate goals and objectives relevant to executive officer compensation, evaluate each executive officer’s performance in light of such goals and objectives, and set each executive officer’s compensation based on such evaluation and such other factors as the Audit Committee deems appropriate and in the best interests of the Company (including the cost to the Company of such compensation). Notwithstanding the foregoing, currently none of the Company’s executive officers are directly compensated by the Company. However, the Company reimburses its administrator for the allocable portion of overhead and other expenses incurred by the administrator in performing its obligations under an administration agreement, including an allocable share of the compensation of certain of the Company’s executive officers with finance and compliance responsibilities.

Nominating Committee

The members of the Nominating Committee are Messrs. Anstiss, Hyman and Tune and Ms. Corley, each of whom is not an interested person and is otherwise independent for purposes of the 1940 Act and Nasdaq’s corporate governance regulations. Mr. Hyman served as chairman of the Nominating Committee, and, effective as of February 26, 2024, Ms. Corley will serve as chair of the Nominating Committee. The Board of Directors has adopted a charter for the Nominating Committee, which is available on the Company’s website at https://investor.fdus.com/corporate-governance.

The Nominating Committee is responsible for selecting, researching and nominating directors for election by the Company’s stockholders, selecting nominees to fill vacancies on the Board of Directors or a committee of the Board of Directors, developing and recommending to the Board of Directors a set of corporate governance principles and overseeing the evaluation of the Board of Directors and its committees.

The Nominating Committee identifies potential nominees based on suggestions from members of the Nominating Committee, other members of the Board of Directors, other executive officers and by other means, and evaluates such persons as a committee. The Nominating Committee will also consider nominees to the Board of Directors recommended by a stockholder, if such stockholder complies with the advance notice provisions of our bylaws. From time to time, the Board of Directors may determine that it requires a director with a particular expertise or qualification and will actively recruit such a candidate.

In considering which persons to nominate as directors for election by stockholders, the Board of Directors and its Nominating Committee consider the experience, qualifications, attributes and skills of candidates, in light of the Company’s then existing business and structure. Additionally, the Nominating Committee generally will hire an outside firm to perform a background check on potential nominees. On an annual basis, the Nominating Committee evaluates the qualifications and diversity of the Board of Directors who are available for reelection in light of the characteristics of independence, age, skills, experience, availability of service to the Company and tenure of its members, and the Board of Directors’ anticipated needs. The Nominating Committee has adopted a policy that it will seek to enhance the perspectives and experiences of the members of the Board of Directors through diversity in gender, ethnic background, geographic origin and professional experience. The Nominating Committee recommends to the Board of Directors for its approval the slate of directors to be nominated for election at the annual meeting of the Company’s stockholders. The Board of Directors and its Nominating Committee periodically review board composition and the policies with respect thereto and as part of this review, the Nominating Committee evaluates the effectiveness of its policies, including the provisions with respect to diversity.

In considering possible candidates for nomination as a director, the Nominating Committee takes into account, in addition to such other factors as it deems relevant, the desirability of selecting directors who have:

17

The Nominating Committee also considers all applicable legal and regulatory requirements that govern the composition of the Board of Directors.

All nominees properly submitted to the Company (or which the Nominating Committee otherwise elects to consider) will be evaluated and considered by the members of the Nominating Committee using the same criteria as nominees identified by the Nominating Committee itself.

COMPENSATION DISCUSSION AND ANALYSIS

Our executive officers do not receive any direct compensation from us. We do not currently have any employees and currently do not expect to have any employees. Services necessary for our business are provided by individuals who are employees or other affiliates of our Investment Advisor, pursuant to the terms of our Investment Advisory Agreement and our administration agreement. Each of our executive officers is an employee or other affiliate of our Investment Advisor. Our day-to-day investment operations are managed by our Investment Advisor. All of the services necessary for the origination and administration of our investment portfolio are provided by investment professionals employed by our Investment Advisor. In addition, we reimburse our Investment Advisor, as administrator, for its allocable portion of expenses incurred by it in performing its obligations under the administration agreement, including its allocable portion of the cost related to certain of our officers, including the Chief Financial Officer and Chief Compliance Officer, and their respective staffs, and for certain expenses under the administration agreement.

Under the Investment Advisory Agreement, our Investment Advisor earned and was paid approximately $32.5 million in fees for the year ended December 31, 2023, consisting of a base management fee, net of base management fee waiver of $16.0 million and an income incentive fee of $16.5 million. For the year ended December 31, 2023, we accrued/(reversed) $2.4 million of capital gains incentive fees in accordance with generally accepted accounting principles. For the year ended December 31, 2023, $3.5 million of the capital gains fee accrued is payable to our Investment Advisor.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

Related Party Transactions Policy and Procedure

The Company has procedures in place for the review, approval and monitoring of transactions involving the Company and certain related persons of the Company. The Company has a written Code of Business Conduct that generally prohibits any officer, director and employee of the Company and employees of its Investment Advisor from engaging in any transaction where there is a conflict between such individual’s personal interest and the interests of the Company. Certain actions or relationships that might give rise to a conflict of interest are reviewed and approved by the Board of Directors. Waivers to the Code of Business Conduct for directors and executive officers can be obtained from the Board of Directors under certain circumstances and will be publicly disclosed as required by applicable law and regulations. In addition, the Audit Committee reviews and preapproves all related-party transactions (as defined in Item 404 of Regulation S-K).

Moreover, our Investment Advisor has enacted a conflict-resolution policy that addresses the co-investment restrictions set forth under the 1940 Act and the allocation of investment opportunities. The 1940 Act generally prohibits us from making certain negotiated co-investments with affiliates unless we first obtain an order from the SEC permitting us to do so. Where co-investments can be made, or where an investment opportunity becomes available to one investment vehicle managed by our Investment Advisor, then an equitable allocation must be made with respect to the investment.

The Company has obtained exemptive relief allowing us to engage in certain co-investment transactions with our affiliates that would otherwise be prohibited by the 1940 Act, as applicable to BDCs. The Company also obtained exemptive relief that permits the Company and a wholly-owned subsidiary that is licensed by the U.S. Small Business Administration (the “SBA”) as a small business investment company (an “SBIC”) to operate effectively as one company, specifically allowing them to: (1) engage in certain transactions with each other; (2) invest in securities in which the other is or proposes to be an investor; (3) file consolidated reports with the Commission; and (4) be subject to modified consolidated asset coverage requirements for senior securities issued by a BDC and its SBIC subsidiary. Our second and third wholly-owned SBIC subsidiaries, Fidus Mezzanine Capital II, L.P. and Fidus Mezzanine Capital III, L.P. (collectively, the “Funds”) have not elected to be treated as a BDC and is not party to this exemptive relief. 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 Funds, from the definition of senior securities in the 150% asset coverage requirement applicable to the Company under the 1940 Act.

If we invest alongside other accounts managed by our Investment Advisor, our Investment Advisor will seek to ensure the equitable allocation of investment opportunities between us and the other relevant accounts. If we invest alongside such other accounts as permitted by the 1940 Act and related rules, such investments will be made consistent with our Investment Advisor’s allocation policy. Under this allocation policy, a fixed percentage of each opportunity, which may vary based on asset class and from time to time, will be offered to us and similar eligible accounts, as periodically determined by our Investment Advisor and approved by our Board of Directors, including our independent directors. The allocation policy provides that allocations among us and other accounts will generally be made pro rata based on each account’s capital available for investment, as determined, in our case, by our Board of Directors, including our independent directors. It is our policy to make our determinations as to the amount of capital available for investment based on such factors as the amount of cash on hand, existing commitments and reserves, if any, the targeted leverage level, the targeted asset mix and diversification requirements and other investment policies and restrictions set by our Board of Directors, or imposed by applicable laws, rules, regulations or interpretations. We expect that these determinations will be made similarly for other accounts. On January 4, 2017, the SEC granted us an exemptive order that expands our ability to co-invest in portfolio companies with certain of our affiliates managed by our investment advisor in a manner consistent with our investment objective, positions, policies, strategies and restrictions as well as regulatory requirements and other pertinent factors, subject to compliance with certain conditions (the “Order”). Pursuant to

24

the Order, we are permitted to co-invest with our affiliates if a “required majority” (as defined in Section 57(o) of the 1940 Act) of our independent directors make certain conclusions in connection with a co-investment transaction, including that (1) the terms of the transactions, including the consideration to be paid, are reasonable and fair to us and our stockholders and do not involve overreaching by us or our stockholders on the part of any person concerned, and (2) the transaction is consistent with the interests of our stockholders and is consistent with our investment objective and strategies. We intend to co-invest, subject to the conditions included in the Order. However, we nor our affiliated funds are obligated to invest or co-invest when investment opportunities are referred to us or them.

In situations where co-investment with other entities managed by our Investment Advisor is not permitted or appropriate, such as when there is an opportunity to invest in different securities of the same issuer, our Investment Advisor will need to decide whether we or such other entity or entities will proceed with the investment. Our Investment Advisor will make these determinations based on our allocation policy that generally requires that such opportunities be offered to eligible accounts on a basis that will be fair and equitable over time, including, for example, through random or rotational methods.

In addition, certain members of our Investment Advisor and its investment committees are also members of Fidus Partners, LLC (“Partners”), an investment banking firm. Partners may in the future serve as an advisor to our portfolio companies and we may invest in companies that Partners is advising. Partners may receive fees in connection with these advisory services, subject to regulatory restrictions imposed by the 1940 Act.

Fidus Group Holdings, LLC (“Holdings”), a limited liability company organized under the laws of Delaware, is the parent company of the Investment Advisors. Edward H. Ross, our Chairman and Chief Executive Officer, and Thomas C. Lauer, our President, are managers of Holdings.

Certain Transactions With or Involving Related Persons

Investment Advisory Agreement

Under the Investment Advisory Agreement with our Investment Advisor, we pay our Investment Advisor a management fee and incentive fee that consists of an income incentive fee and a capital gains incentive fee. The incentive fee is computed and paid on income that we may not have yet received in cash. This fee structure may create an incentive for our Investment Advisor to invest in certain types of securities that may have a high degree of risk. Additionally, we rely on investment professionals from our Investment Advisor to assist our Board of Directors with the valuation of our portfolio investments. Our Investment Advisor’s management fee and incentive fee are based on the value of our investments and there may be a conflict of interest when personnel of our Investment Advisor are involved in the valuation process for our portfolio investments. The base management fee, net of the base management fee waiver, under the Investment Advisory Agreement for the year ended December 31, 2023 totaled $16.0 million. The income incentive fee expense for the year ended December 31, 2023 totaled $16.5 million. For the year ended December 31, 2023, we accrued/(reversed) $2.4 million of capital gains incentive fees in accordance with generally accepted accounting principles. For the year ended December 31, 2023, $3.5 million of the capital gains fee accrued is payable to our Investment Advisor.

Mr. E. Ross is the chairman of the Board of Directors of the Company and Fund I and the chairman of our Investment Advisor’s investment committees. Moreover, Mr. E. Ross is the Chief Executive Officer of our Investment Advisor. The board of managers of our Investment Advisor, the manager of Fidus Investment GP, LLC, the general partner of the Funds, currently controls the Funds. The following people are members of the board of managers of our Investment Advisor: Messrs. E. Ross, Lauer, J. Ross, John H. Grigg and Andrew W. Worth. Officers and members of the board of managers of our Investment Advisor receive a benefit from the fees paid to our Investment Advisor pursuant to the Investment Advisory Agreement. Our Board of Directors, which consists of a majority of non-interested directors, has approved the Investment Advisory Agreement, including the fees paid pursuant to the Investment Advisory Agreement.

25

Administration Agreement

Pursuant to the administration agreement, our Investment Advisor furnishes us with office facilities and equipment, provides clerical, bookkeeping and record keeping services at such facilities and provides the Company with other administrative services necessary to conduct day-to-day operations. 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 NAV, oversees the preparation and filing of our tax returns and the printing and dissemination of reports to our stockholders, and generally oversees 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. 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 related to certain of our officers, including our Chief Financial Officer and Chief Compliance Officer and their respective staffs. In addition, the Company reimburses the Investment Advisor for fees and expenses incurred while performing due diligence on our prospective portfolio companies including “dead deal” expenses. Under the administration agreement, administrative expenses for services provided for the year ended December 31, 2023 totaled $2.4 million.

Investment Committee

Our Investment Advisor has formed an investment committee to evaluate and approve all of our investments and those made by the Funds. The investment committee process is intended to bring the diverse experience and perspectives of the investment 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 meets regularly to consider our investments, direct our strategic initiatives and supervise the actions taken by our Investment Advisor on our behalf. The investment committee determines appropriate investment sizing and suggest ongoing monitoring requirements. In addition, the investment committee reviews and determines whether to make prospective investments identified by our Investment Advisor and monitors the performance of our investment portfolio.

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.

Portfolio Management

We will only invest in an opportunity with the approval of at least four of the members of the investment committee responsible for advising the Company and the Funds. Generally, an investment opportunity will receive the unanimous approval of the respective investment committee. Follow-on investments in existing portfolio companies require the relevant investment committee’s approval in addition to what was obtained when the initial investment in the company was made. In addition, temporary investments, such as those in cash equivalents, U.S. government securities and other high quality debt investments that mature in one year or less, may require approval by the relevant investment committee. The day-to-day management of investments approved by the investment committee will be overseen by the members of the relevant investment committee.

PROPOSAL NO. 2

APPROVAL TO SELL OR OTHERWISE ISSUE SHARES OF COMMON STOCK BELOW NET ASSET VALUE

The Company is a closed-end investment company that has elected to be treated as a BDC under the 1940 Act. The 1940 Act prohibits the Company from selling shares of its common stock at a price below the Company’s then current NAV per share, with certain exceptions. One such exception would permit the Company to sell shares of its common stock during the next year at a price below the Company’s then current NAV per share if its stockholders approve such a sale and the Company’s directors make certain determinations. Pursuant to this provision, the Company is seeking the approval of its common stockholders so that it may, in one or more public or private offerings of its common stock, sell shares of its common stock at a price below its then current NAV per share, subject to certain conditions discussed below. If approved, the authorization would be effective for a period expiring on the earlier of the one year anniversary of the date of this Annual Meeting or the date of the Company’s 2025 Annual Meeting of Stockholders.

Generally, equity securities sold in public securities offerings are priced based on public market prices quoted on exchanges such as Nasdaq, rather than NAV, or book value, per share. Since the Company’s initial public offering, at times the Company’s common stock has traded above its NAV per share, and at times the Company’s common stock has traded below its NAV per share. Similar to last year, the Company is again seeking the approval of a majority of its common stockholders to authorize the Company, pursuant to approval of the Company’s Board of Directors, to sell or otherwise issue shares of its common stock during the next year at a price below the Company’s then current NAV per share, subject to certain conditions as set forth in this proxy statement (including that the cumulative number of shares sold pursuant to such authority does not exceed 25% of its then outstanding common stock immediately prior to each such sale).

Selling or otherwise issuing shares of the Company’s common stock below its then current NAV per share would result in a dilution of the Company’s existing common stockholders. It should be noted that the maximum number of shares issuable below NAV pursuant to this authority that could result in such dilution is limited to 25% of the Company’s then outstanding common stock immediately prior to each such sale. Furthermore, pursuant to this authority, there would be no limit on the discount to NAV at which shares could be sold. See below for a discussion and examples of the dilutive effect of the issuance of shares below NAV.

Reasons to Offer or otherwise Issue Common Stock Below NAV

We believe that the limited amount of capital available to lower middle-market companies, coupled with the desire of these companies for flexible and partnership-oriented sources of capital, creates an attractive investment environment for us. From our perspective, lower middle-market companies have faced difficulty raising debt capital in both the capital markets and private markets. As a result of the difficulties in the credit markets and fewer sources of capital for lower middle-market companies, we see opportunities for improved risk-adjusted returns. Furthermore, we believe with a large pool of uninvested private equity capital seeking debt capital to complete transactions and a substantial supply of refinancing opportunities, there is an opportunity to attain appealing risk-adjusted returns on debt and equity investments.

As a BDC and a RIC, the Company is dependent on its ability to raise capital through the issuance of common stock. RICs generally must distribute substantially all of their earnings to stockholders as dividends in order to achieve pass-through tax treatment, which prevents the Company from using those earnings to support new investments. Further, BDCs must maintain a debt to equity ratio of less than 1:1 (or 2:1 if certain requirements are satisfied), which requires the Company to finance its investments with at least as much equity as debt in the aggregate. To continue to build the Company’s investment portfolio, and thereby support maintenance and growth of the Company’s dividends, the Company endeavors to maintain consistent access to capital through the public and private equity markets enabling it to take advantage of investment opportunities as they arise.

Although the Company’s common stock has had a relatively limited trading history, it has traded both at a premium and at a discount in relation to its NAV, which is the equivalent of “book value,” rather than market or publicly-traded value. The possibility that shares of our common stock will trade at either a discount from NAV or at premiums that are unsustainable over the long term is separate and distinct from the risk that our NAV will decrease. It is not possible to predict whether any shares of our common stock issued in the future will trade at, above, or below NAV. The Company has had six follow-on equity offerings since closing its IPO in June 2011 and has sold shares under its equity at-the-market program (the ATM Program). Each offering has priced above the Company’s then current NAV. The following table lists the high and low sales prices for our common stock, and the sales prices as percentages of NAV. On March 21, 2024, the last reported closing sale price of our common stock on the Nasdaq Global Select Market was $[●].

Distributions in excess of our current and accumulated profits and earnings would be treated first as a return of capital to the extent of the stockholder’s tax basis, and any remaining distributions would be treated as a

31

capital gain. The determination of the tax attributes of our distributions will be made annually as of the end of our fiscal year based upon our taxable income for the full year and distributions paid for the full year. Therefore, a determination made on a quarterly basis may not be representative of the actual tax attributes of our distributions for a full year. Each year, a statement on Form 1099-DIV identifying the source of the distribution will be sent to our U.S. stockholders of record. No portion of the distributions reported in the table above represented a return of capital.

Credit market dislocation and uncertainty surrounding the U.S. economy may lead to significant stock market volatility, particularly with respect to the stock of financial services companies. We have observed, and continue to observe, supply chain disruptions, labor and resource shortages, commodity inflation, elements of financial market instability (including rapidly rising interest rates), an uncertain economic outlook for the United States (which may include a recession), and elements of geopolitical instability (including the ongoing war in Ukraine, the ongoing war in the Middle East, and U.S. and China relations), each of which can contribute to continuing periods of volatility. During times of increased price volatility, the Company’s common stock may periodically trade below its NAV, which is not uncommon for BDCs like the Company. As noted above, however, market uncertainties have created, and we believe will continue to create, favorable opportunities to invest, including opportunities that, all else being equal, may increase NAV over the longer-term, even if financed with the issuance of common stock below NAV, although there is no assurance that this will occur. The Company expects that it will be periodically presented with attractive opportunities that require the Company to make an investment commitment quickly. The Company may be unable to capitalize on investment opportunities presented to it unless it is able to quickly raise capital. Stockholder approval of the proposal to sell shares below NAV subject to the conditions detailed below will provide the Company with the flexibility to invest in such opportunities.

The Board of Directors believes that having the flexibility to issue its common stock below NAV in certain instances is in the best interests of stockholders. If the Company were unable to access the capital markets as attractive investment opportunities arise, the Company’s ability to grow over time and continue to pay steady or increasing dividends to stockholders could be adversely affected. It could also have the effect of forcing the Company to sell assets that the Company would not otherwise sell, and such sales could occur at times that are disadvantageous to sell.

Conditions to Sales Below NAV

The Company will only sell or otherwise issue shares of its common stock at a price below NAV per share if the following conditions are met:

32

Finally, in determining whether or not to sell additional shares of the Company’s common stock at a price below the NAV per share, the Board of Directors has a duty to act in the best interests of the Company and its stockholders. Shares of common stock sold at prices below then current NAV upon exercise or conversion of any warrants or other securities that may be issued under authority granted by our stockholders at our 2024 annual meeting will not be taken into account in determining whether the 25% limitation described above in this proposal has been reached.

Key Stockholder Considerations

Before voting on this proposal or giving proxies with regard to this matter, common stockholders should consider the dilutive effect of the issuance of shares of the Company’s common stock at less than NAV per share on the NAV per outstanding share of common stock. Any sale of common stock at a price below NAV would result in an immediate dilution to existing common stockholders. Since under this proposal shares of the Company’s common stock or securities otherwise issued could be issued at a price that is substantially below the NAV per share, the dilution could be substantial. This dilution would include reduction in the NAV per share as a result of the issuance of shares at a price below the NAV per share and a proportionately greater decrease in a stockholder’s interest in the earnings and assets of the Company and voting interest in the Company than the increase in the assets of the Company resulting from such issuance. If this Proposal No. 2 is approved, the Board of Directors of the Company may, consistent with its fiduciary duties, approve the sale or otherwise issue shares of the Company’s common stock at any discount to its then current NAV per share; however, the Board of Directors will consider the potential dilutive effect of the issuance of shares at a price below the NAV per share when considering whether to authorize any such issuance and will act in the best interests of the Company and its stockholders in doing so.

The 1940 Act establishes a connection between common share sale price and NAV because, when shares of common stock or other specific securities are sold at a sale price below NAV per share, the resulting increase in the number of outstanding shares is not accompanied by a proportionate increase in the net assets of the issuer. Further, if current stockholders of the Company do not purchase any shares to maintain their percentage interest, regardless of whether such offering is above or below the then current NAV, their voting power will be diluted. For an illustration of the potential dilutive effect of an offering of our common stock at a price below NAV, please see the table below under the heading “Examples of Dilutive Effect of the Issuance of Shares Below NAV.”

It should be noted that the cumulative number of shares sold below NAV pursuant to this approval is limited to 25% of the Company’s then outstanding common stock immediately prior to each such sale. While we aggregate all sales sold below NAV throughout the year for purposes of this limit, the maximum is based on the percentage of outstanding common shares at the time of each offering and if we issue additional shares throughout the year, we would be able to issue more shares below NAV before reaching the 25% limit. Furthermore, there would be no limit on the discount to NAV at which shares could be sold.

Finally, any sale of substantial amounts of our common stock or other securities in the open market may adversely affect the market price of our common stock and may adversely affect our ability to obtain future financing in the capital markets. In addition, future sales of our common stock to the public may create a potential market overhang, which is the existence of a large block of shares readily available for sale that could lead the market to discount the value of shares held by other investors. In the event we were to continue to sell our common stock at prices below NAV for sustained periods of time, such offerings may result in sustained discounts in the marketplace.

Examples of Dilutive Effect of the Issuance of Shares Below NAV

The following table illustrates the level of NAV dilution that would be experienced by a nonparticipating stockholder in four different hypothetical offerings of different sizes and levels of discount from NAV per share, although it is not possible to predict the level of market price decline that may occur. Actual sales prices and discounts may differ from the presentation below.

The examples assume that Company XYZ has 1,000,000 common shares outstanding, $15,000,000 in total assets and $5,000,000 in total liabilities. The current NAV and NAV per share are thus $10,000,000 and $10.00. The table illustrates the dilutive effect on nonparticipating Stockholder A of (1) an offering of 50,000 shares (5% of the outstanding shares) at $9.50 per share after offering expenses and commission (a 5% discount from NAV), (2) an offering of 100,000 shares (10% of the outstanding shares) at $9.00 per share after offering expenses and commissions (a 10% discount from NAV), (3) an offering of 200,000 shares (20% of the outstanding shares) at $8.00 per share after offering expenses and commissions (a 20% discount from NAV), (4) an offering of 250,000 shares (25% of the outstanding shares) at $7.50 per share after offering expenses and commissions (a 25% discount from NAV) and (5) an offering of 250,000 (25% of the outstanding shares) with the proceeds to the Company at $0.00 per share after offering expenses and commissions (a 100% discount from NAV). Under this proposal, there is no limit on the discount at which the Company may sell its shares.

Dilutive Effect of the Issuance of Shares by Company XYZ Below Net Asset Value

Required Vote

Approval of this proposal requires the affirmative vote of (1) a 1940 Act majority of the outstanding shares of common stock entitled to vote at the Annual Meeting; and (2) a 1940 Act majority of the outstanding shares of common stock entitled to vote at the Annual Meeting that are not held by affiliated persons of the Company.

The Board of Directors recommends a vote “FOR” the proposal to authorize the Company, pursuant to approval of the Board of Directors of the Company, to sell or otherwise issue shares of its common stock during the next year at a price below the Company’s then current NAV per share, subject to certain conditions as set forth in this proxy statement (including that the cumulative number of shares sold pursuant to such authority does not exceed 25% of its then outstanding common stock immediately prior to each such sale).

INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Audit Committee of the Board of Directors has selected RSM US LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2023. RSM US LLP also will serve as the independent registered public accounting firm for all of our wholly-owned subsidiaries.

RSM US LLP has advised us that neither the firm nor any present member or associate of it has any material financial interest, direct or indirect, in us or our wholly-owned subsidiaries. It is expected that a representative of RSM US LLP will be present at the Annual Meeting and will have an opportunity to make a statement if he or she chooses and will be available to answer appropriate questions.

Independent Registered Public Accounting Firm’s Fees

We have paid or expect to pay the following fees to RSM US LLP for work performed in 2023 and 2022 or attributable to the audit of our 2023 and 2022 financial statements:

Audit Fees. Audit fees include fees for services that normally would be provided by the accountant in connection with statutory and regulatory filings or engagements and that generally only the independent accountant can provide. In addition to fees for the audit of our annual financial statements, any audit of the effectiveness of our internal control over financial reporting and the review of our quarterly financial statements in accordance with generally accepted auditing standards, this category contains fees for comfort letters, statutory audits, consents, and assistance with and review of documents filed with the SEC.

Audit Related Fees. Audit related fees are assurance related services that traditionally are performed by the independent accountant, such as attest services that are not required by statute or regulation.

Tax Fees. Tax fees include corporate and subsidiary compliance and consulting.

All Other Fees. Fees for other services would include fees for products and services other than the services reported above.

Pre-Approval Policies and Procedures

Our Audit Committee has established, and our Board of Directors has approved a pre-approval policy that describes the permitted audit, audit-related, tax and other services to be provided by RSM US LLP, the Company’s independent registered accounting firm. The policy requires that the Audit Committee pre-approve the audit and non-audit services performed by the independent registered accounting firm in order to assure that the provision of such service does not impair the firm’s independence. The Audit Committee has pre-approved all services by RSM US LLP that were performed during the fiscal year ended December 31, 2023.

36

Any requests for audit, audit-related, tax and other services that have not received general pre-approval must be submitted to the Audit Committee for specific pre-approval, irrespective of the amount. Before the Company engages the independent registered public accounting firm to render a service, the engagement must be either (i) specifically approved by the Audit Committee or (ii) entered into pursuant to the pre-approval policy. Normally, pre-approval is provided at regularly scheduled meetings of the Audit Committee. However, the Audit Committee may delegate pre-approval authority to one or more of its members. The member or members to whom such authority is delegated shall report any pre-approval decisions to the Audit Committee at its next scheduled meeting. The Audit Committee does not delegate its responsibilities to pre-approve services performed by the independent registered accounting firm to management.

AUDIT COMMITTEE REPORT*

The Audit Committee of the Board of Directors of Fidus Investment Corporation operates under a written charter adopted by the Board of Directors, which is available on the Company’s website at https://investor.fdus.com/corporate-governance. The audit committee is comprised of four directors, each of whom is not “interested persons” (as defined in the 1940 Act) of the Company and meets the independence requirements under the applicable listing standards under the Nasdaq Stock Market Rules.

Management is responsible for the Company’s internal controls over the financial reporting process. The Company’s independent registered public accounting firm is responsible for performing an independent audit of the Company’s consolidated financial statements in accordance with auditing standards of the Public Accounting Oversight Board and expressing an opinion on the conformity of those audited financial statements in accordance with accounting principles generally accepted in the United States. The Audit Committee’s responsibility is to monitor and oversee these processes. The Audit Committee is also directly responsible for the appointment, compensation and oversight of the Company’s independent registered public accounting firm.

Review with Management

The Audit Committee has reviewed the audited financial statements and met and held discussions with management regarding the audited financial statements. Management has represented to the Audit Committee that the Company’s consolidated financial statements were prepared in accordance with accounting principles generally accepted in the United States.

Review and Discussion with Independent Registered Public Accounting Firm

The Audit Committee has discussed with RSM US LLP matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board. The Audit Committee received and reviewed the written disclosures and the letter from RSM US LLP required by Public Company Accounting Oversight Board Rule 3526 (Communication with Audit Committee Concerning Independence), and has discussed with RSM US LLP its independence and the compatibility of non-audit services with the firm’s independence.

Conclusion

Based on the Audit Committee’s discussion with management and the Company’s independent registered public accounting firm, the Audit Committee’s review of the audited financial statements, the representations of management and the report of the independent registered public accounting firm to the Audit Committee, the Audit Committee recommended that the Board of Directors include the audited consolidated financial statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023 for filing with the Securities and Exchange Commission. The Audit Committee also appointed RSM US LLP to serve as the Company’s independent registered public accounting firm for the year ending December 31, 2024.
