PRELIMINARY PROSPECTUS SUPPLEMENT

(To Prospectus Dated May 1, 2019)

$                

    % Notes due 2026

We are an externally managed, closed-end, non-diversified management investment company that has elected to be regulated as a business development company (“BDC”) under the Investment Company Act of 1940, as amended (the “1940 Act”). 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 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. We generally invest in securities that would be rated below investment grade if they were rated by rating agencies. Below investment grade securities, which are often referred to as “high yield” or “junk,” have speculative characteristics with respect to the issuer’s capacity to pay interest and repay principal.

Fidus Investment Advisors, LLC serves as our investment advisor and as our administrator.

We are offering $         million in aggregate principal amount of     % notes due 2026 (the “Notes”). The Notes will mature on January 31, 2026. We will pay interest on the Notes on January 31 and July 31 of each year, beginning July 31, 2021. We may redeem the Notes in whole or in part at any time or from time to time, at the redemption price set forth under the section titled “Description of the Notes—Optional Redemption” in this prospectus supplement. In addition, holders of the Notes can require us to repurchase some or all of the Notes at a purchase price equal to 100% of their principal amount, plus accrued and unpaid interest to, but not including, the repurchase date, upon the occurrence of a Change of Control Repurchase Event (as defined herein). The Notes will be issued in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof.

The Notes will be our direct unsecured obligations and rank equal in right of payment with all outstanding and future unsecured, unsubordinated indebtedness issued by us. Because the Notes will not be secured by any of our assets, they will be effectively subordinated to all of our existing and future secured indebtedness (or any indebtedness that is initially unsecured as to which we subsequently grant a security interest) to the extent of the value of the assets securing such indebtedness. The Notes will be structurally subordinated to all existing and future indebtedness and other obligations of any of our subsidiaries because the Notes will be obligations exclusively of Fidus Investment Corporation and not of any of our subsidiaries. The Notes will be senior in right of payment to any future outstanding series of our preferred stock. None of our subsidiaries is a guarantor of the Notes and the Notes will not be required to be guaranteed by any subsidiary we may acquire or create in the future. As of September 30, 2020, we had $352.3 million of debt outstanding of which $329.3 million was unsecured and unsubordinated indebtedness and $23.0 million was secured indebtedness. None of our current indebtedness will be subordinated to the Notes.

We do not intend to list the Notes on any securities exchange or automated dealer quotation system.

Please read these documents before you invest and retain them for future reference. Additional information about us, including our annual, quarterly and current reports and proxy statements, has been filed with the Securities and Exchange Commission (the “SEC”), and can be accessed free of charge at its website at www.sec.gov.

See “Available Information” on page S-41 of this prospectus supplement.

Investing in the Notes involves a high degree of risk, including the risk of leverage. Before buying any Notes, you should read the material risks described in the “Supplementary Risk Factors” section beginning on page S-10 of this prospectus supplement and “Risk Factors” beginning on page 13 of the accompanying prospectus and in our most recent Annual Report on Form 10-K, our most recent Quarterly Report on Form 10-Q, as well as any of our subsequent SEC filings.

THE NOTES ARE NOT DEPOSITS OR OTHER OBLIGATIONS OF A BANK AND ARE NOT INSURED BY THE FEDERAL DEPOSIT INSURANCE CORPORATION OR ANY OTHER GOVERNMENT AGENCY.

Neither the SEC nor any state securities commission, nor any other regulatory body, has approved or disapproved of these securities or determined if this prospectus supplement or the accompanying prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

SUPPLEMENTARY RISK FACTORS

Investing in the Notes involves a number of significant risks. You should carefully consider the risks described below, together with all of the risks and uncertainties described in the section titled “Risk Factors” in the accompanying prospectus, our most recent Annual Report on Form 10-K, our most recent Quarterly Report on Form 10-Q, as well as in subsequent filings with the SEC, which are or will be incorporated by reference into this prospectus supplement and the accompanying prospectus in their entirety, and other information in this prospectus supplement, the accompanying prospectus, the documents incorporated by reference in this prospectus supplement and the accompanying prospectus, and any free writing prospectus that we may authorize for use in connection with this offering. The risks and uncertainties described below are not the only ones facing us. Additional risks and uncertainties not presently known to us, or not presently deemed material by us, may also impair our operations and performance. If any of the following risks actually occur, our business, financial condition or results of operations could be materially adversely affected. If that happens, our net asset value and the trading price of our securities could decline and you may lose all or part of your investment. Please also read carefully the section titled “Special Note Regarding Forward-Looking Statements” in this prospectus supplement.

Risks Related to the Offering

The Notes will be unsecured and therefore will be effectively subordinated to any secured indebtedness we have currently incurred or may incur in the future and will rank pari passu with, or equal to, all outstanding and future unsecured indebtedness issued by and us and our general liabilities (total liabilities, less debt).

The Notes will not be secured by any of our assets or any of the assets of any of our subsidiaries. As a result, the Notes will be effectively subordinated to any secured indebtedness we or our subsidiaries have outstanding as of the date of this prospectus supplement (including under our Credit Facility) or that we or our subsidiaries may incur in the future (or any indebtedness that is initially unsecured as to which we subsequently grant security) to the extent of the value of the assets securing such indebtedness. In any liquidation, dissolution, bankruptcy or other similar proceeding, the holders of any of our existing or future secured indebtedness and the secured indebtedness of our subsidiaries may assert rights against the assets pledged to secure that indebtedness in order to receive full payment of their indebtedness before the assets may be used to pay other creditors, including the holders of the Notes. In addition, the Notes will rank pari passu with, or equal to, all outstanding and future unsecured, unsubordinated indebtedness issued by us and our general liabilities (total liabilities, less debt). As of December 15, 2020, we had $50.0 million in outstanding indebtedness under our Credit Facility. The indebtedness under the Credit Facility is effectively senior to the Notes to the extent of the value of the assets securing such indebtedness.

The Notes will be structurally subordinated to the indebtedness and other liabilities of our subsidiaries.

The Notes will be obligations exclusively of Fidus Investment Corporation, and not of any of our subsidiaries. None of our subsidiaries will be a guarantor of the Notes, and the Notes will not be required to be guaranteed by any subsidiary we may acquire or create in the future. Any assets of our subsidiaries will not be directly available to satisfy the claims of our creditors, including holders of the Notes. Except to the extent we are a creditor with recognized claims against our subsidiaries, all claims of creditors of our subsidiaries will have priority over our equity interests in such entities (and therefore the claims of our creditors, including holders of the Notes) with respect to the assets of such entities. Even if we are recognized as a creditor of one or more of these entities, our claims would still be effectively subordinated to any security interests in the assets of any such entity and to any indebtedness or other liabilities of any such entity senior to our claims. Consequently, the Notes will be structurally subordinated to all indebtedness and other liabilities, including trade payables, of any of our existing or future subsidiaries, including the Funds. As of December 15, 2020, our subsidiaries had total indebtedness outstanding of $147.0 million. Certain of these entities currently serve as guarantors under our Credit Facility,

S-10

and in the future our subsidiaries may incur substantial additional indebtedness, all of which is and would be structurally senior to the Notes.

The indenture under which the Notes will be issued contains limited protection for holders of the Notes.

The indenture under which the Notes will be issued offers limited protection to holders of the Notes. The terms of the indenture and the Notes do not restrict our or any of our subsidiaries’ ability to engage in, or otherwise be a party to, a variety of corporate transactions, circumstances or events that could have an adverse impact on your investment in the Notes. In particular, the terms of the indenture and the Notes will not place any restrictions on our or our subsidiaries’ ability to:

S-11

Furthermore, the terms of the indenture and the Notes do not protect holders of the Notes in the event that we experience changes (including significant adverse changes) in our financial condition, results of operations or credit ratings, if any, as they do not require that we or our subsidiaries adhere to any financial tests or ratios or specified levels of net worth, revenues, income, cash flow, or liquidity.

Our ability to recapitalize, incur additional debt (including additional debt that matures prior to the maturity of the Notes) and take a number of other actions that are not limited by the terms of the Notes may have important consequences for you as a holder of the Notes, including making it more difficult for us to satisfy our obligations with respect to the Notes or negatively affecting the market value of the Notes.

Other debt we issue or incur in the future could contain more protections for its holders than the indenture and the Notes, including additional covenants and events of default. The issuance or incurrence of any such debt with incremental protections could affect the market for, trading levels, and prices of the Notes.

There is no active trading market for the Notes. If an active trading market does not develop for the Notes, you may not be able to sell them.

The Notes are a new issue of debt securities for which there currently is no trading market. We do not intend to list the Notes on any securities exchange or for quotation of the Notes on any automated dealer quotation system. If the Notes are traded after their initial issuance, they may trade at a discount to their initial offering price depending on prevailing interest rates, the market for similar securities, our credit ratings, our financial condition, performance and prospects, general economic conditions, including the impact of COVID-19, or other relevant factors. Although the underwriter has informed us that it intends to make a market in the Notes, it is not obligated to do so, and the underwriter may discontinue any market-making in the Notes at any time at its sole discretion. Accordingly, we cannot assure you that a liquid trading market will develop or be maintained for the Notes, that you will be able to sell your Notes at a particular time or that the price you receive when you sell will be favorable. To the extent an active trading market does not develop, the liquidity and trading price for the Notes may be harmed. Accordingly, you may be required to bear the financial risk of an investment in the Notes for an indefinite period of time.

If we default on our obligations to pay our other indebtedness, we may not be able to make payments on the Notes.

Any default under the agreements governing our indebtedness, including a default under the Credit Facility, the indenture governing our 2023 Notes, the indenture governing our February 2024 Notes, the indenture governing our November 2024 Notes or other indebtedness to which we may be a party, that is not waived by the required lenders or holders, and the remedies sought by the lenders or holders of such indebtedness could make us unable to pay principal, premium, if any, and interest on the Notes and substantially decrease the market value of the Notes. If we are unable to generate sufficient cash flow and are otherwise unable to obtain funds necessary to meet required payments of principal, premium, if any, and interest on our indebtedness, or if we otherwise fail to comply with the various covenants, including financial and operating covenants, as applicable, in the instruments governing our indebtedness, we could be in default under the terms of the agreements governing such indebtedness. In the event of such default, the holders of such indebtedness could elect to declare all the funds borrowed thereunder to be due and payable, together with accrued and unpaid interest, the lenders under the Credit Facility or other debt we may incur in the future could elect to terminate their commitments, cease making further loans and institute foreclosure proceedings against our assets, and we could be forced into bankruptcy or liquidation. If our operating performance declines, we may in the future need to refinance or restructure our debt, including the Notes, sell assets, reduce or delay capital investments, seek to raise additional capital or seek to obtain waivers from the required lenders under the Credit Facility or other debt that we may incur in the future to avoid being in default. If we are unable to implement one or more of these alternatives, we may not be able to meet our payment obligations under the Notes or our other debt. If we breach our covenants under the Credit Facility or our other debt and seek a waiver, we may not be able to obtain a waiver from the required lenders or

S-12

holders thereof. If this occurs, we would be in default under the Credit Facility or other debt, the lenders or holders could exercise their rights as described above, and we could be forced into bankruptcy or liquidation. If we are unable to repay debt, lenders having secured obligations, including the lenders under the Credit Facility, could proceed against the collateral securing the debt. Because the Credit Facility has, the indenture will have, and any future credit facilities will likely have, customary cross-default provisions, if the indebtedness under the Notes, the Credit Facility or under any future credit facility is accelerated, we may be unable to repay or finance the amounts due.

We may choose to redeem the Notes when prevailing interest rates are relatively low.

The Notes are redeemable in whole or in part upon certain conditions at any time or from time to time at our option. We may choose to redeem the Notes from time to time, especially if prevailing interest rates are lower than the rate borne by the Notes. If prevailing rates are lower at the time of redemption, and we redeem the Notes, you likely would not be able to reinvest the redemption proceeds in a comparable security at an effective interest rate as high as the interest rate on the Notes being redeemed.

We may not be able to repurchase the Notes upon a Change of Control Repurchase Event.

We may not be able to repurchase the Notes upon a Change of Control Repurchase Event because we may not have sufficient funds. We would not be able to borrow under our Credit Facility to finance such a repurchase of the Notes, and we expect that any future credit facility would have similar limitations. Upon a Change of Control Repurchase Event, holders of the Notes may require us to repurchase for cash some or all of the Notes at a repurchase price equal to 100% of the aggregate principal amount of the Notes being repurchased, plus accrued and unpaid interest to, but not including, the repurchase date. The terms of our Credit Facility also provide that certain change of control events will constitute an event of default thereunder entitling the lenders to accelerate any indebtedness outstanding under our Credit Facility at that time and to terminate our Credit Facility. Our and our subsidiaries’ future financing facilities may contain similar restrictions and provisions. Our failure to purchase such tendered Notes upon the occurrence of such Change of Control Repurchase Event would cause an event of default under the indenture governing the Notes and a cross-default under the agreements governing the Credit Facility, which may result in the acceleration of such indebtedness requiring us to repay that indebtedness immediately. If the holders of the Notes exercise their right to require us to repurchase Notes upon a Change of Control Repurchase Event, the financial effect of this repurchase could cause a default under our current and future debt instruments, and we may not have sufficient funds to repay any such accelerated indebtedness. See “Description of the Notes—Offer to Repurchase Upon a Change of Control Repurchase Event” in this prospectus supplement for more information.

A downgrade, suspension or withdrawal of the credit rating assigned by a rating agency to us or the Notes or change in the debt markets could cause the liquidity or market value of the Notes to decline significantly.

Our credit ratings are an assessment by rating agencies of our ability to pay our debts when due. Consequently, real or anticipated changes in our credit ratings will generally affect the market value of the Notes. These credit ratings may not reflect the potential impact of risks relating to the structure or marketing of the Notes. Credit ratings are not a recommendation to buy, sell or hold any security, and may be revised or withdrawn at any time by the issuing organization in its sole discretion. Neither we nor any underwriter undertakes any obligation to maintain our credit ratings or to advise holders of Notes of any changes in our credit ratings. There can be no assurance that our credit ratings will remain for any given period of time or that such credit ratings will not be lowered or withdrawn entirely by the rating agencies if in their judgment future circumstances relating to the basis of the credit ratings, such as adverse changes in our Company, so warrant. The conditions of the financial markets and prevailing interest rates have fluctuated in the past and are likely to fluctuate in the future, which could have an adverse effect on the market prices of the Notes.

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

Information included or incorporated by reference in this prospectus supplement, the accompanying prospectus and in any free writing prospectus relating to this offering of the Notes may contain “forward-looking statements.” These forward-looking statements are not historical facts, but rather are based on current expectations, estimates and projections about us, our current and prospective portfolio investments, our industry, our beliefs, and our assumptions. Although we believe that the assumptions on which these forward-looking statements are based are reasonable, any of those assumptions could prove to be inaccurate, and as a result, the forward-looking statements based on those assumptions also could be inaccurate. Important assumptions include our ability to originate new loans and investments, certain margins and levels of profitability and the availability of additional capital. In light of these and other uncertainties, the inclusion of a projection or forward-looking statement in this prospectus should not be regarded as a representation by us that our plans and objectives will be achieved. Words such as “anticipates,” “expects,” “intends,” “plans,” “will,” “may,” “continue,” “believes,” “seeks,” “estimates,” “would,” “should,” “targets,” “projects” and variations of these words and similar expressions are intended to identify forward-looking statements. The forward-looking statements contained in this prospectus supplement, the accompanying prospectus, and in any free writing prospectus relating to this offering of Notes involve risks and uncertainties, including statements as to:

These statements are not guarantees of future performance and are subject to risks, uncertainties and other factors, some of which are beyond our control and difficult to predict and could cause actual results to differ materially from those expressed or forecasted in the forward-looking statements, including without limitation:

S-14

We caution readers not to place undue reliance on any such forward-looking statements, which speak only as of the date made. Actual results could differ materially from those anticipated in our forward-looking statements and future results could differ materially from our historical performance. Except as required by law, we undertake no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, after the date of this prospectus supplement. Although we undertake no obligation to revise or update any forward-looking statements, whether as a result of new information, future events, or otherwise, you are advised to consult any additional disclosures that we may make directly to you or through reports or other documents we have filed, or in the future may file, with the SEC, including subsequent annual reports on Form 10-K, quarterly reports on Form 10-Q and current reports on Form 8-K.

S-15

USE OF PROCEEDS

We estimate that the net proceeds we receive from the sale of $         aggregate principal amount of the Notes in this offering will be approximately $         after deducting the underwriting discount of approximately $         payable by us and estimated offering expenses of approximately $         payable by us.

We intend to use the net proceeds from this offering to redeem all of the outstanding 2023 Notes and repay a portion of the amount outstanding under the Credit Facility. However, we may re-borrow under our Credit Facility and use such borrowings to invest in lower middle-market companies in accordance with our investment objective and strategies and for working capital and general corporate purposes. As of December 15, 2020, we had $50.0 million of indebtedness outstanding under our Credit Facility. Our Credit Facility matures on April 24, 2023, and borrowings under the Credit Facility currently bear interest, at our election, at a rate per annum equal to (a) 3.00% (or 2.75% if certain conditions are satisfied, including if (x) no equity interests are included in the borrowing base, (y) the contribution to the borrowing base of eligible portfolio investments that are performing first lien bank loans is greater than or equal to 35%, and (z) the contribution to the borrowing base of eligible portfolio investments that are performing first lien bank loans, performing last out loans, or performing second lien loans is greater than or equal to 60%) plus the one, two, three or six month adjusted LIBOR, as applicable, or (b) 2.00% (or 1.75% if the above conditions are satisfied) plus the highest of (A) a prime rate, (B) the federal funds effective rate plus 0.5%, (C) the three month adjusted LIBOR plus 1.0%, and (D) zero.

CAPITALIZATION

The following table sets forth our capitalization as of September 30, 2020:

S-17

DESCRIPTION OF THE NOTES

The Notes will be issued under a base indenture dated as of February 2, 2018 and a fourth supplemental indenture thereto, to be entered into between us and U.S. Bank National Association, as trustee. We refer to the indenture and the fourth supplemental indenture collectively as the “indenture” and to U.S. Bank National Association as the “trustee.” The Notes are governed by the indenture, as required by federal law for all bonds and notes of companies that are publicly offered. An indenture is a contract between us and the financial institution acting as trustee on your behalf, and is subject to and governed by the Trust Indenture Act of 1939, as amended. The trustee has two main roles. First, the trustee can enforce your rights against us if we default. There are some limitations on the extent to which the trustee acts on your behalf, described in the second paragraph under “—Events of Default—Remedies if an Event of Default Occurs” below. Second, the trustee performs certain administrative duties for us with respect to the Notes.

This section includes a summary description of the material terms of the Notes and the indenture. Because this section is a summary, however, it does not describe every aspect of the Notes and the indenture. We urge you to read the indenture because it, and not this description, defines your rights as a holder of the Notes. The base indenture has been attached as an exhibit to the registration statement of which this prospectus supplement is a part and the fourth supplemental indenture will be attached as an exhibit to a Current Report on Form 8-K, in each case, as filed with the SEC. See “Available Information” in this prospectus supplement for information on how to obtain a copy of the indenture.

General

The Notes will mature on January 31, 2026. The principal payable at maturity will be 100% of the aggregate principal amount. The interest rate of the Notes is     % per year and will be paid semi-annually in arrears on January 31 and July 31 of each year, commencing July 31, 2021, and the regular record dates for interest payments will be every January 15 and July 15, commencing July 15, 2021. If an interest payment date falls on a non-business day, the applicable interest payment will be made on the next business day and no additional interest will accrue as a result of such delayed payment. The initial interest period will be the period from and including December    , 2020, to, but excluding, the initial interest payment date, and the subsequent interest periods will be the periods from and including an interest payment date to, but excluding, the next interest payment date or the stated maturity date, as the case may be.

We will issue the Notes in denominations of $2,000 and integral multiples of $1,000 in excess thereof. The Notes will not be subject to any sinking fund.

The indenture does not limit the amount of debt (including secured debt) that may be issued by us or our subsidiaries under the indenture or otherwise, but does contain a covenant regarding our asset coverage that would have to be satisfied at the time of our incurrence of additional indebtedness. See “—Other Covenants” and “—Events of Default” below. The indenture does not otherwise contain any financial covenants or restrict us from paying dividends or issuing or repurchasing our other securities other than as described in “—Other Covenants” below. Other than restrictions described under “—Merger, Consolidation or Asset Sale” below, the indenture does not contain any covenants or other provisions designed to afford holders of the Notes protection in the event of a highly leveraged transaction involving us or if our credit rating declines as the result of a takeover, recapitalization, highly leveraged transaction or similar restructuring involving us that could adversely affect your investment in the Notes.

We may, without the consent of the holders of the Notes, issue additional notes under the indenture with the same terms (except for the issue date, public offering price, and if applicable, the initial interest payment date) and with the same CUSIP numbers as the Notes offered hereby in an unlimited aggregate principal amount; provided that such additional notes must be treated as part of the same issue as the Notes offered hereby for U.S. federal

S-18

income tax purposes. In addition, we have the ability to issue indenture securities with terms different from the Notes.

We do not intend to list the Notes on any securities exchange or automated dealer quotation system.

Optional Redemption

The Notes may be redeemed in whole or in part at any time or from time to time at our option, upon not less than 30 days nor more than 60 days written notice by mail prior to the date fixed for redemption thereof, at a redemption price (as determined by us) equal to the greater of the following amounts, plus, in each case, accrued and unpaid interest to, but excluding, the redemption date: (1) 100% of the principal amount of the Notes to be redeemed or (2) the sum of the present values of the remaining scheduled payments of principal and interest (exclusive of accrued and unpaid interest to the date of redemption) on the Notes to be redeemed, discounted to the redemption date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) using the applicable Treasury Rate plus 50 basis points; provided, however, that if we redeem any Notes on or after October 31, 2025 (the date falling three months prior to the maturity date of the Notes), the redemption price for the Notes will be equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the date of redemption; provided, further, that no such partial redemption shall reduce the portion of the principal amount of a Note not redeemed to less than $2,000.

You may be prevented from exchanging or transferring the Notes when they are subject to redemption. In case any Notes are held in certificate form and are to be redeemed in part only, the redemption notice will provide that, upon surrender of such Note, you will receive, without a charge, a new Note or Notes of authorized denominations representing the principal amount of your remaining unredeemed Notes. Any exercise of our option to redeem the Notes will be done in compliance with the indenture, the terms of our Credit Facility and, to the extent applicable, the 1940 Act.

If we redeem only some of the Notes, the trustee or, with respect to global securities, DTC will determine the method for selection of the particular Notes to be redeemed, in accordance with the indenture and the 1940 Act, to the extent applicable. Unless we default in payment of the redemption price, on and after the date of redemption, interest will cease to accrue on the Notes called for redemption.

For purposes of calculating the redemption price in connection with the redemption of the Notes, on any redemption date, the following terms have the meanings set forth below:

“Comparable Treasury Issue” means the United States Treasury security selected by the Reference Treasury Dealer as having a maturity comparable to the remaining term of the Notes to be redeemed that would be utilized, at the time of selection and in accordance with customary financing practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of the Notes being redeemed.

“Comparable Treasury Price” means (1) the average of the Reference Treasury Dealer Quotations for the redemption date, after excluding the highest and lowest Reference Treasury Dealer Quotations, or (2) if the Quotation Agent obtains fewer than four such Reference Treasury Dealer Quotations, the average of all such quotations.

“Quotation Agent” means a Reference Treasury Dealer selected by us.

“Reference Treasury Dealer” means each of any four primary U.S. government securities dealers selected by us.

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by the Quotation Agent, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to

S-19

the Quotation Agent by such Reference Treasury Dealer at 3:30 p.m. New York time on the third business day preceding such redemption date. All determinations made by any Reference Treasury Dealer, including the Quotation Agent, with respect to determining the redemption price will be final and binding absent manifest error.

“Treasury Rate” means, with respect to any redemption date, the rate per annum equal to the semi-annual equivalent yield-to-maturity of the Comparable Treasury Issue (computed as of the third business day immediately preceding the redemption), assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such redemption date. The redemption price and the Treasury Rate will be determined by us.

Offer to Repurchase Upon a Change of Control Repurchase Event

If a Change of Control Repurchase Event occurs, unless we have exercised our right to redeem the Notes in full, we will make an offer to each holder of Notes to repurchase all or any part (in minimum denominations of $2,000 and integral multiples of $1,000 principal amount) of that holder’s Notes at a repurchase price in cash equal to 100% of the aggregate principal amount of Notes repurchased plus any accrued and unpaid interest on the Notes repurchased to the date of purchase. Within 30 days following any Change of Control Repurchase Event or, at our option, prior to any Change of Control, but after the public announcement of the Change of Control, we will mail a notice to each holder describing the transaction or transactions that constitute or may constitute the Change of Control Repurchase Event and offering to repurchase Notes on the payment date specified in the notice, which date will be no earlier than 30 days and no later than 60 days from the date such notice is mailed. The notice shall, if mailed prior to the date of consummation of the Change of Control, state that the offer to purchase is conditioned on the Change of Control Repurchase Event occurring on or prior to the payment date specified in the notice. We will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control Repurchase Event. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control Repurchase Event provisions of the Notes, we will comply with the applicable securities laws and regulations and will not be deemed to have breached our obligations under the Change of Control Repurchase Event provisions of the Notes by virtue of such conflict.

On the Change of Control Repurchase Event payment date, subject to extension if necessary to comply with the provisions of the 1940 Act, we will, to the extent lawful:

The paying agent will promptly remit to each holder of Notes properly tendered the purchase price for the Notes, and the trustee will promptly authenticate and mail (or cause to be transferred by book-entry) to each holder a new Note equal in principal amount to any unpurchased portion of any Notes surrendered; provided that each new Note will be in a minimum principal amount of $2,000 or an integral multiple of $1,000 in excess thereof.

We will not be required to make an offer to repurchase the Notes upon a Change of Control Repurchase Event if a third party makes an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by us and such third party purchases all Notes properly tendered and not withdrawn under its offer. The source of funds that will be required to repurchase Notes in the event of a Change of Control Repurchase Event will be our available cash or cash generated from our operations or other potential sources, including funds

S-20

provided by a purchaser in the Change of Control transaction, borrowings, sales of assets or sales of equity. We cannot assure you that sufficient funds from such sources will be available at the time of any Change of Control Repurchase Event to make required repurchases of Notes tendered. Before making any such repurchase of Notes, we would also have to comply with certain requirements under our Credit Facility, to the extent such requirements remain in effect at such time, or otherwise obtain consent from the lenders under the Credit Facility. The terms of our Credit Facility also provide that certain change of control events will constitute an event of default thereunder entitling the lenders to accelerate any indebtedness outstanding under our Credit Facility at that time and to terminate the Credit Facility. In addition, the occurrence of a Change of Control Repurchase Event enabling the holders of the Notes to require the mandatory purchase of the Notes would likely constitute an event of default under our Credit Facility, entitling the lenders to accelerate any indebtedness outstanding under our Credit Facility at that time and to terminate the Credit Facility. Our and our subsidiaries’ future financing facilities may contain similar provisions or other restrictions. Our failure to purchase such tendered Notes upon the occurrence of such Change of Control Repurchase Event would cause an event of default under the indenture governing the Notes and a cross-default under the Credit Facility and agreements governing other indebtedness, which may result in the acceleration of such indebtedness requiring us to repay that indebtedness immediately. If the holders of the Notes exercise their right to require us to repurchase Notes upon a Change of Control Repurchase Event, the financial effect of this repurchase could cause a default under our future debt instruments, even if the Change of Control Repurchase Event itself would not cause a default. It is possible that we will not have sufficient funds at the time of the Change of Control Repurchase Event to make the required repurchase of the Notes and/or our other debt.

The definition of “Change of Control” includes a phrase relating to the direct or indirect sale, transfer, conveyance or other disposition of “all or substantially all” of our properties or assets and those of our subsidiaries taken as a whole. Although there is a limited body of case law interpreting the phrase “substantially all,” there is no precise, established definition of the phrase under applicable law. Accordingly, the ability of a holder of Notes to require us to repurchase the Notes as a result of a sale, transfer, conveyance or other disposition of less than all of our assets and the assets of our subsidiaries taken as a whole to another person or group may be uncertain.

For purposes of the Notes:

“Below Investment Grade Rating Event” means the Notes are downgraded below Investment Grade by the Rating Agency on any date from the date of the public notice of an arrangement that results in a Change of Control until the end of the 60-day period following public notice of the occurrence of a Change of Control (which period shall be extended so long as the rating of the Notes is under publicly announced consideration for possible downgrade by the Rating Agency); provided that a Below Investment Grade Rating Event otherwise arising by virtue of a particular reduction in rating shall not be deemed to have occurred in respect of a particular Change of Control (and thus shall not be deemed a Below Investment Grade Rating Event for purposes of the definition of Change of Control Repurchase Event hereunder) if the Rating Agency does not announce or publicly confirm or inform the trustee in writing at its request (acting at the direction of holders of a majority in Principal amount of the Notes) that the reduction was the result, in whole or in part, of any event or circumstance comprised of or arising as a result of, or in respect of, the applicable Change of Control (whether or not the applicable Change of Control shall have occurred at the time of the Below Investment Grade Rating Event).

“Change of Control” means the occurrence of any of the following:

S-21

“Change of Control Repurchase Event” means the occurrence of a Change of Control and a Below Investment Grade Rating Event.

“Controlled Subsidiary” means any subsidiary of Fidus Investment Corporation, 50% or more of the outstanding equity interests of which are owned by Fidus Investment Corporation and its direct or indirect subsidiaries and of which Fidus Investment Corporation possesses, directly or indirectly, the power to direct or cause the direction of the management or policies, whether through the ownership of voting equity interests, by agreement or otherwise.

“Egan-Jones” means Egan-Jones Ratings Company or any successor thereto.

“Investment Grade” means a rating of BBB- or better by Egan-Jones (or its equivalent under any successor rating categories of Egan-Jones) (or, if such Rating Agency ceases to rate the Notes for reasons outside of our control, the equivalent investment grade credit rating from any Rating Agency selected by us as a replacement Rating Agency).

“Permitted Holders” means (i) us, (ii) one or more of our Controlled Subsidiaries or (iii) the Adviser, any affiliate of the Adviser or any entity that is managed or advised by the Adviser or any of their affiliates.

“Rating Agency” means:

“Voting Stock” as applied to stock of any person, means shares, interests, participations or other equivalents in the equity interest (however designated) in such person having ordinary voting power for the election of a majority of the directors (or the equivalent) of such person, other than shares, interests, participations or other equivalents having such power only by reason of the occurrence of a contingency.

Global Securities

Each Note will be issued in book-entry form and represented by a global security that we deposit with and register in the name of DTC or its nominee. A global security may not be transferred to or registered in the name of anyone other than the depositary or its nominee, unless special termination situations arise. As a result of these arrangements, the depositary, or its nominee, will be the sole registered owner and holder of all the Notes represented by a global security, and investors will be permitted to own only beneficial interests in a global security. For more information about these arrangements, see “—Book- Entry Procedures” below.

Termination of a Global Security

If a global security is terminated for any reason, interests in it will be exchanged for certificates in non-book-entry form (certificated securities). After that exchange, the choice of whether to hold the certificated Notes

S-22

directly or in street name will be up to the investor. Investors must consult their own banks or brokers to find out how to have their interests in a global security transferred on termination to their own names, so that they will be holders.

Conversion and Exchange

The Notes are not convertible into or exchangeable for other securities.

Payment and Paying Agents

We will pay interest to the person listed in the trustee’s records as the owner of the Notes at the close of business on a particular day in advance of each due date for interest, even if that person no longer owns the Note on the interest due date. That day, usually about two weeks in advance of the interest due date, is called the “record date.” Because we will pay all the interest for an interest period to the holders on the record date, holders buying and selling the Notes must work out between themselves the appropriate purchase price. The most common manner is to adjust the sales price of the Notes to prorate interest fairly between buyer and seller based on their respective ownership periods within the particular interest period. This prorated interest amount is called “accrued interest.”

Payments on Global Securities

We will make payments on the Notes so long as they are represented by a global security in accordance with the applicable policies of the depositary as in effect from time to time. Under those policies, we will make payments directly to the depositary, or its nominee, and not to any indirect holders who own beneficial interests in the global security. An indirect holder’s right to those payments will be governed by the rules and practices of the depositary and its participants, as described under “—Book-Entry Procedures” below.

Payments on Certificated Securities

In the event the Notes become represented by certificated securities, we will make payments on the Notes as follows. We will pay interest that is due on an interest payment date to the holder of the Notes as shown on the trustee’s records as of the close of business on the regular record date. We will make all payments of principal and premium, if any, by check at the office of the applicable trustee in New York, New York and/or at other offices that may be specified in the indenture or a notice to holders against surrender of the Note.

Alternatively, if the holder asks us to do so, we will pay any amount that becomes due on the debt security by wire transfer of immediately available funds to an account at a bank in New York, New York, on the due date. To request payment by wire, the holder must give the applicable trustee or other paying agent appropriate written transfer instructions at least 15 business days before the requested wire payment is due. In the case of any interest payment due on an interest payment date, the instructions must be given by the person who is the holder on the relevant regular record date. Any wire instructions, once properly given, will remain in effect unless and until new instructions are given in the manner described above.

Payment When Offices Are Closed

If any payment is due on the Notes on a day that is not a business day, we will make the payment on the next day that is a business day. Payments made on the next business day in this situation will be treated under the indenture as if they were made on the original due date. Such payment will not result in a default under the Notes or the indenture, and no interest will accrue on the payment amount from the original due date to the next day that is a business day.

S-23

Book-entry and other indirect holders should consult their banks or brokers for information on how they will receive payments on the Notes.

Events of Default

You will have rights if an Event of Default occurs in respect of the Notes and the Event of Default is not cured, as described later in this subsection.

The term “Event of Default” in respect of the Notes means any of the following:

An Event of Default for the Notes may, but does not necessarily, constitute an Event of Default for any other series of debt securities issued under the same or any other indenture. Within 90 days after the occurrence of any default under the indenture with respect to the Notes, the trustee shall transmit notice to the holders of such default known to the trustee, unless such default shall have been cured or waived; provided, however, that, except in the case of a default in the payment of the principal of (or premium, if any, on) or interest, if any, on any Note, the trustee shall be protected in withholding such notice if and so long as the board of directors, the executive committee or a trust committee of directors of the trustee in good faith determines that withholding of such notice is in the interest of the holders of the Notes; and provided further that in the case of any default or breach specified in the third bullet point above with respect to the Notes, no such notice shall be given until at least 60 days after the occurrence thereof.

Remedies if an Event of Default Occurs

If an Event of Default has occurred and is continuing, then and in every case (other than an Event of Default specified in the penultimate bullet point above), the trustee or the holders of not less than 25% in principal amount of the Notes may declare the entire principal amount of all the Notes to be due and immediately payable,

S-24

but this does not entitle any holder of Notes to any redemption payout or redemption premium. Notwithstanding the foregoing, in the case of the events of bankruptcy, insolvency or reorganization described in the penultimate bullet point above, 100% of the principal of and accrued and unpaid interest on the Notes will automatically become due and payable. In certain circumstances, a declaration of acceleration of maturity pursuant to either of the prior two sentences may be canceled by the holders of a majority in principal amount of the Notes if (1) we have deposited with the trustee all amounts due and owing with respect to the Notes (other than principal or any payment that has become due solely by reason of such acceleration) and certain other amounts, and (2) any other Events of Default have been cured or waived.

Except in cases of default, where the trustee has some special duties, the trustee is not required to take any action under the indenture at the request of any holders unless the holders offer the trustee protection from expenses and liability reasonably satisfactory to it (called an “indemnity”). If indemnity reasonably satisfactory to the trustee is provided, the holders of a majority in principal amount of the Notes may direct the time, method and place of conducting any lawsuit or other formal legal action seeking any remedy available to the trustee. The trustee may refuse to follow those directions in certain circumstances. No delay or omission in exercising any right or remedy will be treated as a waiver of that right, remedy or Event of Default.

Before you are allowed to bypass the trustee and bring your own lawsuit or other formal legal action or take other steps to enforce your rights or protect your interests relating to the Notes, the following must occur:

However, you are entitled at any time to bring a lawsuit for the payment of money due on your Notes on or after the due date.

Book-entry and other indirect holders should consult their banks or brokers for information on how to give notice or direction to or make a request of the trustee and how to declare or cancel an acceleration of maturity.

Each year, we will furnish to the trustee a written statement of certain of our officers certifying that to their knowledge we are in compliance with the indenture and the Notes, or else specifying any default.

Waiver of Default

The holders of a majority in principal amount of the Notes may waive any past defaults other than a default:

Merger, Consolidation or Asset Sale

Under the terms of the indenture, we are generally permitted to consolidate or merge with another entity. We are also permitted to sell all or substantially all of our assets to another entity. However, we may not take any of these actions unless all the following conditions are met:

S-25

An assumption by any person of obligations under the Notes and the indenture might be deemed for U.S. federal income tax purposes to be an exchange of the Notes for new Notes by the holders thereof, resulting in recognition of gain or loss for such purposes and possibly other adverse tax consequences to the holders. Holders should consult their own tax advisors regarding the tax consequences of such an assumption.

Modification or Waiver

There are three types of changes we can make to the indenture and the Notes issued thereunder.

Changes Requiring Your Approval

First, there are changes that we cannot make to your Notes without your specific approval. The following is a list of those types of changes:

Changes Not Requiring Approval

The second type of change does not require any vote by the holders of the Notes. This type is limited to clarifications and certain other changes that would not adversely affect holders of the Notes in any material respect.

Changes Requiring Majority Approval

Any other change to the indenture and the Notes would require the following approval:

In each case, the required approval must be given by written consent. The holders of a majority in principal amount of all of the series of debt securities issued under an indenture, voting together as one class for this purpose, may waive our compliance with some of our covenants in that indenture.

S-26

However, we cannot obtain a waiver of a payment default or of any of the matters covered by the bullet points included above under “—Changes Requiring Your Approval.”

Further Details Concerning Voting

When taking a vote, we will use the following rules to decide how much principal to attribute to the Notes:

The Notes will not be considered outstanding, and therefore not eligible to vote, if we have deposited or set aside in trust money for their payment or redemption or if we or any affiliate of ours own any Notes. The Notes will also not be eligible to vote if they have been fully defeased as described later under “—Defeasance—Full Defeasance” below.

We will generally be entitled to set any day as a record date for the purpose of determining the holders of the Notes that are entitled to vote or take other action under the indenture. However, the record date may not be earlier than 30 days before the date of the first solicitation of holders to vote on or take such action and not later than the date such solicitation is completed. If we set a record date for a vote or other action to be taken by holders of the Notes, that vote or action may be taken only by persons who are holders of the Notes on the record date and must be taken within eleven months following the record date.

Book-entry and other indirect holders should consult their banks or brokers for information on how approval may be granted or denied if we seek to change the indenture or the Notes or request a waiver.

Satisfaction and Discharge

The indenture will be discharged and will cease to be of further effect with respect to the Notes when:

and we, in the case of the first, second and third sub-bullets above, have irrevocably deposited or caused to be deposited with the trustee, as trust, funds in trust solely for the benefit of the holders of the Notes, in amounts as will be sufficient, to pay and discharge the entire indebtedness (including all principal, premium, if any, and interest) on such Notes not previously delivered to the trustee for cancellation (in the case of Notes that have become due and payable on or prior to the date of such deposit) or to the stated maturity or redemption date, as the case may be;

Defeasance

The following provisions will be applicable to the Notes. “Defeasance” means that, by depositing with a trustee an amount of cash and/or government securities sufficient to pay all principal and interest, if any, on the Notes

S-27

when due and satisfying any additional conditions noted below, we will be deemed to have been discharged from our obligations under the Notes. In the event of a “covenant defeasance,” upon depositing such funds and satisfying similar conditions discussed below we would be released from certain covenants under the indenture relating to the Notes.

Covenant Defeasance

Under current U.S. federal income tax law and the indenture, we can make the deposit described below and be released from some of the restrictive covenants in the indenture under which the Notes were issued. This is called “covenant defeasance.” In that event, you would lose the protection of those restrictive covenants but would gain the protection of having money and government securities set aside in trust to repay your Notes. In order to achieve covenant defeasance, the following must occur:

If we accomplish covenant defeasance, you can still look to us for repayment of the Notes if there were a shortfall in the trust deposit or the trustee is prevented from making payment. In fact, if one of the remaining Events of Default occurred (such as our bankruptcy) and the Notes became immediately due and payable, there might be a shortfall. Depending on the event causing the default, you may not be able to obtain payment of the shortfall.

Full Defeasance

The Notes are subject to full defeasance. Full defeasance means that we can legally release ourselves from all payment and other obligations on the Notes, subject to the satisfaction of certain conditions, including, but not limited to that (a) we have received from, or there has been published by, the Internal Revenue Service (the “IRS”) a ruling, or (b) there is a change in U.S. federal income tax law, in either case to the effect that the holders of the Notes and any coupons appertaining thereto will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such defeasance had not occurred (called “full defeasance”), and that we put in place the following other arrangements for you to be repaid:

S-28

If we ever did accomplish full defeasance, as described above, you would have to rely solely on the trust deposit for repayment of the Notes. You could not look to us for repayment in the unlikely event of any shortfall. Conversely, the trust deposit would most likely be protected from claims of our lenders and other creditors if we ever became bankrupt or insolvent.

Other Covenants

In addition to any other covenants described in this prospectus supplement and the accompanying prospectus, as well as standard covenants relating to payment of principal and interest, maintaining an office where payments may be made or securities can be surrendered for payment and related matters, the following covenants will apply to the Notes:

S-29

Form, Exchange and Transfer of Certificated Registered Securities

If registered Notes cease to be issued in book-entry form, they will be issued:

Holders may exchange their certificated securities for Notes of smaller denominations or combined into fewer Notes of larger denominations, as long as the total principal amount is not changed and as long as the denomination is equal to or greater than $2,000.

Holders may exchange or transfer their certificated securities at the office of the trustee. We have appointed the trustee to act as our agent for registering Notes in the names of holders transferring Notes. We may appoint another entity to perform these functions or perform them ourselves.

Holders will not be required to pay a service charge to transfer or exchange their certificated securities, but they may be required to pay any tax (including a withholding tax) or other governmental charge associated with the transfer or exchange. The transfer or exchange will be made only if our transfer agent is satisfied with the holder’s proof of legal ownership.

We may appoint additional transfer agents or cancel the appointment of any particular transfer agent. We may also approve a change in the office through which any transfer agent acts.

If any certificated securities of a particular series are redeemable and we redeem less than all the Notes, we may block the transfer or exchange of those Notes selected for redemption during the period beginning 15 days before the day we mail the notice of redemption and ending on the day of that mailing, in order to freeze the list of holders to prepare the mailing. We may also refuse to register transfers or exchanges of any certificated Notes selected for redemption, except that we will continue to permit transfers and exchanges of the unredeemed portion of any Note that will be partially redeemed.

If registered Notes are issued in book-entry form, only the depositary will be entitled to transfer and exchange the Notes as described in this subsection, since it will be the sole holder of the Notes.

Resignation of Trustee

The trustee may resign or be removed with respect to the Notes provided that a successor trustee is appointed to act with respect to the Notes. In the event that two or more persons are acting as trustee with respect to different series of indenture securities under the indenture, each of the trustees will be a trustee of a trust separate and apart from the trust administered by any other trustee.

Governing Law

The indenture and the Notes will be governed by and construed in accordance with the laws of the State of New York.

Indenture Provisions—Ranking

The Notes will be our direct unsecured obligations and will rank:

S-30

The Trustee under the Indenture

U.S. Bank National Association serves as the trustee, paying agent, and security registrar under the indenture.

Book-Entry Procedures

The Notes will be represented by global securities that will be deposited and registered in the name of DTC or its nominee. This means that, except in limited circumstances, you will not receive certificates for the Notes. Beneficial interests in the Notes will be represented through book-entry accounts of financial institutions acting on behalf of beneficial owners as direct and indirect participants in DTC. Investors may elect to hold interests in the Notes through either DTC, if they are a participant, or indirectly through organizations that are participants in DTC.

The Notes will be issued as fully registered securities registered in the name of Cede & Co. (DTC’s partnership nominee) or such other name as may be requested by an authorized representative of DTC. One fully registered certificate will be issued for each issuance of the Notes, in the aggregate principal amount thereof, and will be deposited with DTC. Interests in the Notes will trade in DTC’s Same Day Funds Settlement System, and any permitted secondary market trading activity in such Notes will, therefore, be required by DTC to be settled in immediately available funds. None of the Company, the trustee or the paying agent will have any responsibility for the performance by DTC or its participants or indirect participants of their respective obligations under the rules and procedures governing their operations.

DTC is a limited-purpose trust company organized under the New York Banking Law, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code, and a “clearing agency” registered pursuant to the provisions of Section 17A of the Exchange Act. DTC holds and provides asset servicing for over 3.5 million issues of U.S. and non-U.S. equity, corporate and municipal debt issues, and money market instruments from over 100 countries that DTC’s participants (“Direct Participants”) deposit with DTC. DTC also facilitates the post-trade settlement among Direct Participants of sales and other securities transactions in deposited securities through electronic computerized book-entry transfers and pledges between Direct Participants’ accounts. This eliminates the need for physical movement of securities certificates. Direct Participants include both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, clearing corporations, and certain other organizations. DTC is a wholly owned subsidiary of The Depository Trust & Clearing Corporation (“DTCC”).

DTCC is the holding company for DTC, National Securities Clearing Corporation and Fixed Income Clearing Corporation, all of which are registered clearing agencies. DTCC is owned by the users of its regulated subsidiaries. Access to the DTC system is also available to others such as both U.S. and non-U.S. securities brokers and dealers, banks, trust companies and clearing corporations that clear through or maintain a custodial relationship with a Direct Participant, either directly or indirectly (“Indirect Participants”). DTC has a Standard & Poor’s Ratings Services’ rating of AA+. The DTC Rules applicable to its participants are on file with the SEC. More information about DTC can be found at www.dtcc.com and www.dtc.org.

Purchases of the Notes under the DTC system must be made by or through Direct Participants, which will receive a credit for the Notes on DTC’s records. The ownership interest of each actual purchaser of each security, or the

S-31

“Beneficial Owner,” is in turn to be recorded on the Direct and Indirect Participants’ records. Beneficial Owners will not receive written confirmation from DTC of their purchase. Beneficial Owners are, however, expected to receive written confirmations providing details of the transaction, as well as periodic statements of their holdings, from the Direct or Indirect Participant through which the Beneficial Owner entered into the transaction. Transfers of ownership interests in the Notes are to be accomplished by entries made on the books of Direct and Indirect Participants acting on behalf of Beneficial Owners. Beneficial Owners will not receive certificates representing their ownership interests in the Notes, except in the event that use of the book-entry system for the Notes is discontinued.

To facilitate subsequent transfers, all Notes deposited by Direct Participants with DTC are registered in the name of DTC’s partnership nominee, Cede & Co. or such other name as may be requested by an authorized representative of DTC. The deposit of the Notes with DTC and their registration in the name of Cede & Co. or such other DTC nominee do not effect any change in beneficial ownership. DTC has no knowledge of the actual Beneficial Owners of the Notes; DTC’s records reflect only the identity of the Direct Participants to whose accounts the Notes are credited, which may or may not be the Beneficial Owners. The Direct and Indirect Participants will remain responsible for keeping account of their holdings on behalf of their customers.

Conveyance of notices and other communications by DTC to Direct Participants, by Direct Participants to Indirect Participants, and by Direct Participants and Indirect Participants to Beneficial Owners will be governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect from time to time.

Redemption notices shall be sent to DTC. If less than all of the Notes within an issue are being redeemed, DTC’s practice is to determine by lot the amount of the interest of each Direct Participant in such issue to be redeemed.

Redemption proceeds, distributions, and interest payments on the Notes will be made to Cede & Co., or such other nominee as may be requested by an authorized representative of DTC. DTC’s practice is to credit Direct Participants’ accounts upon DTC’s receipt of funds and corresponding detail information from us or the trustee on the payment date in accordance with their respective holdings shown on DTC’s records. Payments by participants to Beneficial Owners will be governed by standing instructions and customary practices, as is the case with securities held for the accounts of customers in bearer form or registered in “street name,” and will be the responsibility of such participant and not of DTC nor its nominee, the trustee, or us, subject to any statutory or regulatory requirements as may be in effect from time to time. Payment of redemption proceeds, distributions, and interest payments to Cede & Co. (or such other nominee as may be requested by an authorized representative of DTC) is the responsibility of us or the trustee, but disbursement of such payments to Direct Participants will be the responsibility of DTC, and disbursement of such payments to the Beneficial Owners will be the responsibility of Direct and Indirect Participants.

DTC may discontinue providing its services as securities depository with respect to the Notes at any time by giving reasonable notice to us or to the trustee. Under such circumstances, in the event that a successor securities depository is not obtained, certificates are required to be printed and delivered. We may decide to discontinue use of the system of book-entry-only transfers through DTC (or a successor securities depository). In that event, certificates will be printed and delivered to DTC.

The information in this section concerning DTC and DTC’s book-entry system has been obtained from sources that we believe to be reliable, but neither we nor the underwriter take any responsibility for its accuracy.

S-32

CERTAIN U.S. FEDERAL INCOME TAX CONSEQUENCES

The following discussion summarizes certain material U.S. federal income tax consequences of acquiring, owning and disposing of the Notes. The discussion is based upon the Code; current, temporary and proposed U.S. Treasury Regulations issued thereunder (the “Treasury Regulations”); the legislative history of the Code; IRS rulings, pronouncements, interpretations and practices; and judicial decisions now in effect, all of which are subject to change at any time. Any such change may be applied retroactively in a manner that could adversely affect a holder of the Notes. This discussion is limited to persons purchasing the Notes for cash at original issue and at the offering price on the cover page of this prospectus supplement. Furthermore, this discussion assumes that each holder holds the Notes as “capital assets” within the meaning of Section 1221 of the Code (generally, property held for investment). It does not reflect every possible tax outcome or consequence that could result from acquiring, owning or disposing of the Notes. For example, special rules not discussed here may apply to you if you are:

This discussion also does not address the U.S. federal income tax consequences to beneficial owners of the Notes subject to the special tax accounting rules under Section 451(b) of the Code. In addition, this discussion does not reflect state, local or non-U.S. tax consequences that may apply to you based on your particular circumstances and residence. This discussion also does not address any U.S. federal tax consequences, such as the estate tax or gift tax, other than U.S. federal income tax consequences. You should consult your own tax advisors to determine the tax consequences particular to your situation, including any applicable state, local or foreign income and other tax consequences, which may result from your acquisition, ownership or disposition of the Notes.

As used herein, “U.S. holder” means a beneficial owner of the Notes that is, for U.S. federal income tax purposes:

S-33

If any entity treated as a partnership for U.S. federal income tax purposes holds the Notes, the tax treatment of an owner of such entity generally will depend upon the status of the owner and the activities of the entity. If you are an owner of an entity treated as a partnership for U.S. federal income tax purposes, you should consult your tax advisor regarding the tax consequences of the entity’s purchase, ownership and disposition of the Notes. This discussion does not address the special treatment under U.S. federal income tax law that could result if we invested in tax-exempt securities or certain other investment assets. For purposes of this discussion, “non-U.S. holder” means a beneficial owner of the Notes that is neither a U.S. holder nor an entity treated as a partnership for U.S. federal income tax purposes.

Prospective holders considering purchasing the Notes should consult their own tax advisors concerning the application of the U.S. federal tax laws to their individual circumstances, as well as any consequences to such holders relating to purchasing, owning and disposing of the Notes under the laws of any other taxing jurisdiction.

U.S. Holders

If you are not a U.S. holder, this section does not apply to you.

Interest. The following discussion assumes that the Notes will be issued with no original issue discount or a de minimis amount of original issue discount for U.S. federal income tax purposes. A U.S. holder generally will be required to recognize and include in gross income any stated interest as ordinary income at the time it is paid or accrued on the Notes in accordance with such U.S. holder’s method of accounting for U.S. federal income tax purposes.

Sale or other taxable disposition of the Notes. A U.S. holder will recognize gain or loss on the sale, exchange, redemption, retirement or other taxable disposition of a Note equal to the difference between the sum of the cash and the fair market value of any property received in exchange therefor (less a portion allocable to any accrued and unpaid stated interest, which generally will be taxable as ordinary income if not previously included in such U.S. holder’s income) and the U.S. holder’s adjusted tax basis in the Note. A U.S. holder’s adjusted tax basis in a Note (or a portion thereof) generally will be the U.S. holder’s cost therefor. This gain or loss generally will be long-term capital gain or loss if the U.S. holder has held the Notes for more than one year at the time of such disposition. Long-term capital gains recognized by non-corporate U.S. holders are subject to reduced tax rates. The deductibility of capital losses may be subject to limitations.

Additional tax on net investment income. An additional surtax at a rate of 3.8% is imposed on the amount of “net investment income,” in the case of an individual, or undistributed “net investment income,” in the case of an estate or trust (other than a charitable trust), which exceeds certain threshold amounts. “Net investment income” as defined for this purpose generally includes interest payments and gain recognized from the sale or other taxable disposition of the Notes. U.S. holders should consult their own tax advisors regarding the effect, if any, of this surtax on their ownership and disposition of the Notes.

Information reporting and backup withholding. A U.S. holder may be subject to information reporting and backup withholding when such U.S. holder receives interest and principal payments on the Notes or proceeds upon the sale or other disposition of such Notes (including a redemption or retirement of the Notes). Certain U.S. holders (including, among others, corporations and certain tax-exempt organizations) generally are not subject to

S-34

information reporting or backup withholding. A U.S. holder will be subject to backup withholding if such holder is not otherwise exempt and any of the following is true:

A U.S. holder should consult its tax advisor regarding its qualification for an exemption from backup withholding and the procedures for obtaining such an exemption, if applicable. Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules from a payment to a U.S. holder generally will be allowed as a credit against the U.S. holder’s U.S. federal income tax liability or may be refunded, provided the required information is furnished in a timely manner to the IRS.

Non-U.S. Holders

If you are not a non-U.S. holder, this section does not apply to you.

Interest. Subject to the discussion below concerning FATCA, interest paid to a non-U.S. holder on its Notes that is not effectively connected with such non-U.S. holder’s conduct of a United States trade or business (and, if any applicable treaty so provides, is not attributable to the conduct of a trade or business through a permanent establishment or fixed base in the United States) will not be subject to U.S. federal withholding tax, provided that:

A non-U.S. holder generally will also be exempt from withholding tax on interest if such amount is effectively connected with such non-U.S. holder’s conduct of a United States trade or business and the non-U.S. holder provides us with appropriate certification (as discussed below under the caption “—United States trade or business”).

S-35

Subject to the discussion below under “—United States trade or business,” if a non-U.S. holder does not satisfy the requirements above, interest paid to such non-U.S. holder generally will be subject to a 30% U.S. federal withholding tax. Such rate may be reduced or eliminated under a tax treaty between the United States and the non-U.S. holder’s country of residence. To claim a reduction or exemption under a tax treaty, a non-U.S. holder must generally complete an IRS Form W-8BEN or an IRS Form W-8BEN-E (or applicable successor form) and claim the reduction or exemption on the form.

Sale or other taxable disposition of the Notes. Subject to the discussion below concerning FATCA, a non-U.S. holder generally will not be subject to U.S. federal income tax or withholding tax on gain recognized on the sale, exchange, redemption, retirement or other taxable disposition of a Note so long as (i) the gain is not effectively connected with the conduct by the non-U.S. holder of a United States trade or business (or, if a tax treaty applies, the gain is not attributable to a United States permanent establishment maintained by such non-U.S. holder) and (ii) in the case of a non-U.S. holder who is an individual, such non-U.S. holder is not present in the United States for 183 days or more in the taxable year of disposition and certain other requirements are not met. A non-U.S. holder who is an individual and does not meet this exemption should consult his or her tax advisor regarding the potential liability for U.S. federal income tax on such holder’s gain realized on a Note.

United States trade or business. If interest paid on a Note or gain from a disposition of a Note is effectively connected with a non-U.S. holder’s conduct of a United States trade or business (and, if an income tax treaty applies, the non-U.S. holder maintains a United States permanent establishment to which such amounts are generally attributable), the non-U.S. holder generally will be subject to U.S. federal income tax on the interest or gain on a net basis in the same manner as if it were a U.S. holder. If a non-U.S. holder is subject to U.S. federal income tax on the interest on a net basis, the 30% withholding tax described above will not apply (assuming an appropriate certification is timely provided, generally on IRS Form W-8ECI). A non-U.S. holder that is a corporation may be subject to a branch profits tax equal to 30% of its effectively connected earnings and profits for the taxable year, subject to certain adjustments, unless it qualifies for a lower rate under an applicable income tax treaty. For this purpose, interest on a Note or gain from a disposition of a Note will be included in earnings and profits if the interest or gain is effectively connected with the conduct by the corporation of a United States trade or business.

Backup withholding and information reporting. A non-U.S. holder generally will not be subject to backup withholding and information reporting with respect to payments that we make to the non-U.S. holder, provided that we do not have actual knowledge or reason to know that such holder is a “United States person,” within the meaning of the Code, and the non-U.S. holder has given us the statement described above under “Non-U.S. Holders—Interest.” In addition, a non-U.S. holder will not be subject to backup withholding or information reporting with respect to the proceeds of the sale or other disposition of the Notes (including a retirement or redemption of such Notes) within the United States or conducted through certain U.S.-related brokers, if the payor receives the statement described above and does not have actual knowledge or reason to know that such holder is a United States person or the holder otherwise establishes an exemption. However, we may be required to report annually to the IRS and to the non-U.S. holder the amount of, and the tax withheld with respect to, any interest paid to the non-U.S. holder, regardless of whether any tax was actually withheld. Copies of these information returns may also be made available under the provisions of a specific treaty or agreement to the tax authorities of the country in which the non-U.S. holder resides.

A non-U.S. holder generally will be entitled to credit any amounts withheld under the backup withholding rules against the holder’s U.S. federal income tax liability or may claim a refund provided that the required information is furnished to the IRS in a timely manner.

Foreign Account Tax Compliance Act. Sections 1471 through 1474 of the Code and the Treasury Regulations and other published guidance promulgated thereunder (which are commonly referred to as “FATCA”) generally impose withholding taxes on certain types of payments made to “foreign financial institutions” and certain other non-U.S. entities unless additional certification, information reporting and other specified requirements are

S-36

satisfied (including, in the case of a foreign financial institution, entering into an agreement to, among other requirements, identify financial accounts owned by certain of its direct and indirect U.S. investors). Failure to comply with the FATCA reporting requirements could result in withholding tax being imposed on payments of interest and sales proceeds to foreign intermediaries and certain non-U.S. holders. An intergovernmental agreement between the United States and an applicable foreign country, or future Treasury regulations or other guidance, may modify these requirements. While existing Treasury Regulations would require FATCA withholding on payments of the gross proceeds from the sale of any property that could produce U.S. source interest or dividends, the U.S. Treasury Department has recently released proposed regulations that eliminated this requirement. Pursuant to these proposed regulations, a taxpayer may (but is not required to) rely on this proposed change to FATCA withholding until final regulations are issued or until such proposed regulations are rescinded. The FATCA withholding tax will apply to all withholdable payments without regard to whether the beneficial owner of the payment would otherwise be entitled to an exemption from imposition of withholding tax pursuant to an applicable tax treaty with the United States or U.S. domestic law. If payment of this withholding tax is made, holders that are otherwise eligible for an exemption from, or reduction of, U.S. federal withholding taxes with respect to such interest or proceeds will be required to seek a credit or refund from the IRS to obtain the benefit of such exemption or reduction, if any. We will not pay additional amounts to holders of the Notes in respect of any amounts withheld. Prospective holders should consult their own tax advisors regarding the potential application of withholding under FATCA to their investment in the Notes.

UNDERWRITING

Raymond James & Associates, Inc. is acting as the sole underwriter for this offering. Subject to the terms and conditions set forth in an underwriting agreement dated December     , 2020 between us and the underwriter, we have agreed to sell to the underwriter, and the underwriter has agreed to purchase from us, the $         aggregate principal amount of Notes.

The underwriting agreement provides that the obligations of the underwriter to pay for and accept delivery of the Notes are subject to certain conditions precedent such as the receipt by the underwriter of officers’ certificates and legal opinions. The underwriting agreement provides that the underwriter will purchase all of the Notes if any of the Notes are purchased. We have agreed to indemnify the underwriter against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”), or to contribute to payments the underwriter may be required to make in respect of those liabilities.

The underwriter is offering the Notes, subject to its acceptance of the Notes from us and subject to prior sale. The underwriter reserves the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.

The underwriter has agreed to purchase the Notes from us at     % of the aggregate principal amount of the Notes, which will result in aggregate proceeds to us of approximately $         million, after deducting the underwriting discount and the estimated offering expenses payable by us.

Commissions and Discounts

An underwriting discount of     % per Note will be paid by us. The underwriter has advised us that it proposes initially to offer the Notes to the public at the public offering price on the cover of this prospectus supplement and may offer the Notes to certain other Financial Institution Regulatory Authority, Inc. (FINRA) members at that price less a concession not in excess of     % of the aggregate principal amount of the Notes. The underwriter may allow, and the dealers may reallow, a discount not in excess of    % of the aggregate principal amount of the Notes. After the initial offering of the Notes to the public, the public offering price and such concessions may be changed. No such change shall change the amount of proceeds to be received by us as set forth on the cover page of this prospectus supplement.

The following table shows the total underwriting discount that we are to pay to the underwriter in connection with this offering.

The expenses of the offering, not including the underwriting discount, are estimated at $ and are payable by us. We will pay the fees and expenses (including the reasonable fees and disbursements of underwriter’s counsel in an amount not to exceed $7,500) incident to securing any required review by FINRA of the terms of the sale of the Notes in this offering.

No Sales of Similar Securities

We have agreed not to directly or indirectly offer, sell, short sell or otherwise dispose of, or enter into any agreement to offer, sell, short sell or otherwise dispose of, any debt securities issued or guaranteed by us or other securities convertible into or exchangeable or exercisable for debt securities issued or guaranteed by us or derivative of debt securities issued or guaranteed by us for a period of 90 days after the date of this prospectus supplement without first obtaining the written consent of Raymond James & Associates, Inc. This consent may be given at any time without public notice.

S-38

Listing

We do not intend to list the Notes on any securities exchange or automated dealer quotation system.

We have been advised by the underwriter that it presently intends to make a market in the Notes after completion of the offering as permitted by applicable laws and regulations. The underwriter is not obligated, however, to make a market in the Notes and any such market-making may be discontinued at any time in the sole discretion of the underwriter without any notice. Accordingly, no assurance can be given as to the liquidity of, or development of a public trading market for, the Notes. If an active public trading market for the Notes does not develop, the market price and liquidity of the Notes may be adversely affected.

Stabilization

In connection with the offering, the underwriter may purchase and sell Notes in the open market. These transactions may include short sales, purchases to cover positions created by short sales and stabilizing transactions. Short sales involve the sale by the underwriter of a greater number of Notes than required to be purchased in this offering. Covering transactions involve purchases of the Notes in the open market after the distribution has been completed in order to cover short positions. Stabilizing transactions consist of certain bids or purchases of Notes made for the purpose of preventing or retarding a decline in the market price of the Notes while the offering is in progress.

Any of these activities may cause the price of the Notes to be higher than the price that otherwise would exist in the open market in the absence of such transactions. These transactions may be affected in the over-the-counter market or otherwise and, if commenced, may be discontinued at any time without any notice relating thereto.

Neither we nor the underwriter make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of the Notes. In addition, neither we nor the underwriter make any representation that the underwriter will engage in these transactions or that these transactions, once commenced, will not be discontinued without notice.

Electronic Distribution

A prospectus in electronic format may be made available by e-mail or on the web sites or through online services maintained by the underwriter participating in this offering, or by its affiliates. In those cases, prospective investors may view offering terms online and may be allowed to place orders online. The underwriter may agree with us to allocate a limited principal amount of the Notes for sale to online brokerage account holders. Any such allocation for online distributions will be made by the underwriter on the same basis as other allocations. Other than the prospectus in electronic format, information on the underwriter’s web sites and any information contained in any other web site maintained by the underwriter is not part of this prospectus supplement or the registration statement of which this prospectus supplement is a part, has not been approved and/or endorsed by us or the underwriter and should not be relied on by investors.

Other Relationships

The underwriter and its affiliates have provided in the past and may provide from time to time in the future in the ordinary course of their business certain commercial banking, financial advisory, investment banking and other services to us, our portfolio companies or our affiliates for which they have received or will be entitled to receive separate fees. In particular, the underwriter or its affiliates may execute transactions with us, on behalf of us, any of our portfolio companies or our affiliates. In addition, the underwriter or its affiliates may act as arrangers, underwriters or placement agents for companies whose securities are sold to or whose loans are syndicated to us, our portfolio companies or our affiliates.

S-39

The underwriter or its affiliates may also trade in our securities, securities of our portfolio companies or other financial instruments related thereto for their own accounts or for the account of others and may extend loans or financing directly or through derivative transactions to us, any of our portfolio companies or our affiliates.

After the date of this prospectus supplement, the underwriter and its affiliates may from time to time obtain information regarding specific portfolio companies or us that may not be available to the general public. Any such information is obtained by the underwriter and its affiliates in the ordinary course of its business and not in connection with the offering of the Notes. In addition, after the offering period for the sale of the Notes, the underwriter or its affiliates may develop analyses or opinions related to us or our portfolio companies and buy or sell interests in one or more of our portfolio companies on behalf of their proprietary or client accounts and may engage in competitive activities. There is no obligation on behalf of these parties to disclose their respective analyses, opinions or purchase and sale activities regarding any portfolio company or regarding us to our noteholders or any other persons.

In the ordinary course of their various business activities, the underwriter and its affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers. Such investments and securities activities may involve securities and/or instruments of ours or our affiliates. The underwriter and its affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

The principal business address of the underwriter is as follows: Raymond James & Associates, Inc., 880 Carillon Parkway, St. Petersburg, Florida 33716.

Alternative Settlement Cycle

We expect that delivery of the Notes will be made against payment therefor on or about December    , 2020, which will be the third business day following the date of pricing of the Notes (such settlement cycle being herein referred to as “T+3”). Under Rule 15c6-1 under the Exchange Act, trades in the secondary market generally are required to settle in two business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the Notes on any date prior to the second business day before delivery thereof will be required, by virtue of the fact that the Notes initially will settle T+3, to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement. Purchasers of the Notes who wish to trade the Notes prior to their date of delivery hereunder should consult their own advisors.

Other Jurisdictions

Other than in the United States, no action has been taken by us or the underwriter that would permit a public offering of the Notes offered by this prospectus supplement in any jurisdiction where action for that purpose is required. The Notes offered by this prospectus supplement may not be offered or sold, directly or indirectly, nor may this prospectus supplement or any other offering material or advertisements in connection with the offer and sale of any such Notes be distributed or published in any jurisdiction, except under circumstances that will result in compliance with the applicable rules and regulations of that jurisdiction. Persons into whose possession this prospectus supplement comes are advised to inform themselves about and to observe any restriction relating to the offering and the distribution of this prospectus supplement. This prospectus supplement and the accompanying prospectus do not constitute an offer to sell or a solicitation of an offer to buy the Notes offered by this prospectus supplement and the accompanying prospectus in any jurisdiction in which such an offer or a solicitation is unlawful.

$300,000,000

Common Stock

Preferred Stock

Subscription Rights

Debt Securities

Warrants

We may offer, from time to time, in one or more offerings or series, together or separately, up to $300,000,000 of our common stock, preferred stock, subscription rights, debt securities, or warrants representing rights to purchase shares of our common stock, preferred stock, or debt securities, which we refer to collectively as the “securities.” There are $231,000,000 of securities available for issuance under this prospectus as a result of our issuance of our 6.000% notes due 2024 (the “2024 Notes”) in February 2019 for an aggregate principal amount of $69,000,000. We may sell our common stock through underwriters or dealers, “at-the-market” to or through a market maker into an existing trading market or otherwise directly to one or more purchasers or through agents or through a combination of methods of sale. The identities of such underwriters, dealers, market makers or agents, as the case may be, will be described in one or more supplements to this prospectus. The securities may be offered at prices and on terms to be described in one or more supplements to this prospectus.

We may offer shares of common stock at a discount to net asset value per share in certain circumstances. On June 7, 2018, our common stockholders voted to allow us to sell or otherwise issue common stock at a price below net asset value per share for a period of one year ending on the earlier of June 7, 2019 or the date of our 2019 Annual Meeting of Stockholders. We expect to present to our stockholders a similar proposal at our 2019 Annual Meeting of Stockholders. Sales of common stock at prices below net asset value per share dilute the interests of existing stockholders, have the effect of reducing our net asset value per share and may reduce our market price per share. In addition, continuous sales of common stock below net asset value may have a negative impact on total returns and could have a negative impact on the market price of our shares of common stock. See “Risk Factors” on page 12 and “Sales of Common Stock Below Net Asset Value” on page 101 of this prospectus for more information.

Our stockholders specified that the cumulative number of shares sold in each offering during the one-year period ending on the earlier of June 7, 2019 or the date of our 2019 Annual Meeting of Stockholders may not exceed 25.0% of our outstanding common stock immediately prior to such sale. In addition, we cannot issue shares of our common stock below net asset value unless our board of directors determines that it would be in our and our stockholders’ best interests to do so. Shares of closed-end investment companies such as us frequently trade at a discount to their net asset value. This risk is separate and distinct from the risk that our net asset value per share may decline. We cannot predict whether our common stock will trade above, at or below net asset value. You should read this prospectus and the applicable prospectus supplement carefully before you invest in our common stock.

We provide customized debt and equity financing solutions to lower middle-market companies located throughout the United States. We are an externally managed, closed-end, non-diversified management investment company that has elected to be regulated as a business development company under the Investment Company Act of 1940, as amended. 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 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.

We generally invest in securities that would be rated below investment grade if they were rated. Below investment grade securities, which are often referred to as “high yield” or “junk,” have speculative characteristics with respect to our capacity to pay interest and repay principal.

Our common stock is listed on the Nasdaq Global Select Market under the symbol “FDUS.” On April 24, 2019, the last reported sale price of our common stock on the Nasdaq Global Select Market was $15.46 per share and our net asset value on December 31, 2018 was $16.47 per share.

Fidus Investment Advisors, LLC serves as our investment advisor and as our administrator.

Investing in our securities is speculative and involves numerous risks, and you could lose your entire investment if any of the risks occur. Among these risks is the risk associated with leverage and dilution. For more information regarding these risks, please see “Risk Factors” beginning on page 13.

Please read this prospectus and the accompanying prospectus supplement, if any, before investing, and keep it for future reference. It concisely sets forth important information about us that a prospective investor ought to know before investing in our securities. We file annual, quarterly and current reports, proxy statements and other information about us with the Securities and Exchange Commission.

There are $231,000,000 of securities available for issuance under this prospectus as a result of our issuance of our 6.000% notes due 2024 (the “2024 Notes”) in February 2019 for an aggregate principal amount of $69,000,000.

FEES AND EXPENSES

The following table is intended to assist you in understanding the costs and expenses that an investor in this offering will bear directly or indirectly. We caution you that some of the percentages indicated in the table below are estimates and may vary. Except where the context suggests otherwise, whenever this prospectus contains a reference to fees or expenses paid by “you,” “us,” “the Company” or “Fidus,” or that “we” will pay fees or expenses, stockholders will indirectly bear such fees or expenses as investors in us.

The incentive fee consists of two parts:

The first, payable quarterly in arrears, equals 20.0% of our pre-incentive fee net investment income, expressed as a rate of return on the value of our net assets, (including interest that is accrued but not yet received in cash), subject to a 2.0% quarterly (8.0% annualized) hurdle rate and a “catch-up” provision measured as of the end of each calendar quarter. Under this provision, in any calendar quarter, our investment advisor receives no incentive fee until our pre-incentive fee net investment income equals the

-10-

hurdle rate of 2.0% but then receives, as a “catch-up,” 100.0% of our pre-incentive fee net investment income with respect to that portion of such pre-incentive fee net investment income, if any, that exceeds the hurdle rate but is less than 2.5%. The effect of this provision is that, if pre-incentive fee net investment income exceeds 2.5% in any calendar quarter, our investment advisor will receive 20.0% of our pre-incentive fee net investment income as if a hurdle rate did not apply.

The second part, payable annually in arrears, equals 20.0% of our realized capital gains net of realized capital losses and unrealized capital depreciation, if any, on a cumulative basis from inception through the end of the fiscal year (or upon the termination of the Investment Advisory Agreement, as of the termination date), less the aggregate amount of any previously paid capital gain incentive fees. In accordance with U.S. GAAP, we accrue the capital gains incentive fee in our consolidated financial statements considering the fair value of investments on that date (i.e., the amount of fee which would be payable under a hypothetical liquidation based on the fair value of investments as of that date), which differs from the calculation of the amount payable in cash by the inclusion of unrealized capital appreciation.

See “Management and Other Agreements—Investment Advisory Agreement.”

-11-

Example

The following example demonstrates the projected dollar amount of total cumulative expenses over various periods with respect to a hypothetical investment in us. In calculating the following expense amounts, we have assumed we would have no additional leverage, that none of our assets are cash or cash equivalents and that our annual operating expenses would remain at the levels set forth in the table above. Transaction expenses are not included in the following example.

The foregoing table is to assist you in understanding the various costs and expenses that an investor in our common stock will bear directly or indirectly. While the example assumes, as required by the SEC, a 5.0% annual return, our performance will vary and may result in a return greater or less than 5.0%. Assuming a 5.0% annual return, the incentive fee under the Investment Advisory Agreement would either not be payable or have an insignificant impact on the expense amounts shown above. If we achieve sufficient returns on our investments, including through the realization of capital gains, to trigger an incentive fee of a material amount, our expenses, and returns to our investors, would be higher. In addition, while the example assumes reinvestment of all distributions at net asset value, if our board of directors authorizes and we declare a cash dividend, participants in our dividend reinvestment plan who have not otherwise elected to receive cash will receive a number of shares of our common stock, determined by dividing the total dollar amount of the distribution payable to a participant by the market price per share of our common stock at the close of trading on the valuation date for the distribution. See “Dividend Reinvestment Plan” for additional information regarding our dividend reinvestment plan.

This example and the expenses in the table above should not be considered a representation of our future expenses, and actual expenses (including the cost of debt, if any, and other expenses) may be greater or less than those shown.

RISK FACTORS

Investing in our securities involves a number of significant risks. You should carefully consider these risk factors, together with all of the other information included in this prospectus, or any prospectus supplement. The risks set out below are not the only risks we face. Additional risks and uncertainties not presently known to us or not presently deemed material by us may also impair our operations and performance. If any of the following events occur, our business, financial condition, results of operations and cash flows could be materially and adversely affected. In such case, our net asset value and the trading price of our common stock could decline, and you may lose all or part of your investment.

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.

We depend on the investment expertise, skill and network of business contacts of the managing members of our investment advisor, who evaluate, negotiate, structure, execute and monitor our investments. Our future success will depend to a significant extent on the continued service and coordination of the investment professionals of our investment advisor and executive officers. Certain investment professionals and executives may not devote all of their business time to our operations and may have other demands on their time as a result of other activities. The departure of any of these individuals could have a material adverse effect on our ability to achieve our investment objective.

Our business model depends, to a significant extent, upon strong referral relationships with financial institutions, sponsors and investment professionals. Any inability of our investment advisor to maintain or develop these relationships, or the failure of these relationships to generate investment opportunities, could adversely affect our business.

We depend upon the investment professionals of our investment advisor to maintain their relationships with financial institutions, sponsors and investment professionals, and we intend to rely to a significant extent upon these relationships to provide us with potential investment opportunities. If the investment professionals of our investment advisor fail to maintain such relationships, or to develop new relationships with other sources of investment opportunities, we will not be able to grow our investment portfolio. In addition, individuals with whom the investment professionals of our investment advisor have relationships are not obligated to provide us with investment opportunities, and, therefore, we can offer no assurance that these relationships will generate investment opportunities for us in the future.

Our financial condition and results of operation depends on our ability to manage our business effectively.

Our ability to achieve our investment objective and grow depends on our ability to manage our business and deploy our capital effectively. This depends, in turn, on our investment advisor’s ability to identify, evaluate and monitor companies that meet our investment criteria. Accomplishing our investment objectives on a cost-effective basis depends upon our investment advisor’s execution of our investment process, its ability to provide competent, attentive and efficient services to us and, to a lesser extent, our access to financing on acceptable terms. Our investment advisor has substantial responsibilities under the Investment Advisory Agreement. In addition, our investment advisor’s investment professionals may be called upon to provide managerial assistance to our portfolio companies. These activities may distract them or slow our rate of investment. Any failure to manage our business and our future growth effectively could have a material adverse effect on our business, financial condition and results of operations.

We may suffer credit losses and our investments could be rated below investment grade.

Private debt in the form of second lien, subordinated, and first lien (senior secured or unitranche loans) to corporate and asset-based borrowers is highly speculative and involves a high degree of risk of credit loss, and therefore an investment in our shares of common stock may not be suitable for someone with a low tolerance for risk. These risks are likely to increase during an economic recession.

In addition, investments in our portfolio are typically not rated by any rating agency. We believe that if such investments were rated, the vast majority would be rated below investment grade (which is sometimes referred to as “junk”) due to speculative characteristics of the issuer’s capacity to pay interest and repay principal. Our investments may result in an amount of risk, volatility or potential loss of principal that is greater than that of alternative investments.

Because we borrow money and may in the future issue additional senior securities, including preferred stock and debt securities, the potential for gain or loss on amounts invested in us is magnified and may increase the risk of investing in us.

Borrowings, also known as leverage, magnify the potential for gain or loss on amounts invested and, therefore, increase the risks associated with investing in us. The Funds borrow from and issue debt securities to the SBA, and we may borrow from banks and other lenders in the future. The SBA has fixed dollar claims on the Funds’ assets that are superior to the claims of our stockholders. We may also borrow from banks and other lenders or issue additional senior securities including preferred stock and debt securities in the future. If the value of our assets increases, then leveraging would cause the net asset value attributable to our common stock to increase more sharply than it would have had we not used leverage. Conversely, if the value of our assets decreases, leveraging would cause net asset value to decline more sharply than it otherwise would have had we not leveraged. Similarly, any increase in our income in excess of interest payable on the borrowed funds would cause our net income to increase more than it would without the leverage, while any decrease in our income would cause net income to decline more sharply than it would have had we not borrowed. Such a decline could negatively affect our ability to make distributions to our stockholders. Leverage is generally considered a speculative investment technique.

Our ability to achieve our investment objectives may depend in part on our ability to achieve additional leverage on favorable terms by borrowing from the SBA, banks or other lenders, and there can be no assurance that such additional leverage can in fact be achieved.

As a BDC, we are generally required to meet a coverage ratio at least equal to 200.0% (or 150.0% if we satisfy certain requirements in the future) of total assets to total borrowings and other senior securities, which include all of our borrowings (other than the Funds’ SBA leverage under the terms of SEC exemptive relief) and any preferred stock we may issue in the future. If this ratio declines below 200.0% (or 150.0% if we satisfy certain requirements in the future), we may not be able to incur additional debt and may need to sell a portion of our investments to repay some debt when it is disadvantageous to do so, and we may not be able to make distributions to our stockholders.

The following table illustrates the effect of leverage on returns from an investment in our common stock assuming various annual returns, net of expenses. The calculations in the table below are hypothetical and actual returns may be higher or lower than those appearing in the table below.

Assumed Return on Our Portfolio

(Net of Expenses)

-14-

Funding a portion of our investments with preferred stock would magnify the potential for gain or loss and the risks of investing in us in the same way as our other borrowings.

Preferred stock, which is another form of leverage, has the same risks to our common stockholders as borrowings because the distributions with respect to any preferred stock must be cumulative. Payment of such distributions and repayment of the liquidation preference of such preferred stock must take preference over any distributions or other payments to our common stockholders, and preferred stockholders are not subject to any of our expenses or losses and are not entitled to participate in any income or appreciation in excess of their stated preference.

Legislation that took effect in 2018 would allow us to incur additional leverage.

As a BDC, under the 1940 Act generally we are not permitted to incur indebtedness unless immediately after such borrowing we have an asset coverage for total borrowings of at least 200.0% (i.e., the amount of debt may not exceed 50.0% of the value of our assets). However, legislation that took effect in 2018 has modified the 1940 Act by allowing a BDC to increase the maximum amount of leverage it may incur from an asset coverage ratio of 200.0% to an asset coverage ratio of 150.0%, if certain requirements are met. Under the legislation, we are allowed to increase our leverage capacity if stockholders representing at least a majority of the votes cast, when quorum is met, approve a proposal to do so. If we receive stockholder approval, we would be allowed to increase our leverage capacity on the first day after such approval. Alternatively, the legislation allows the “required majority” of our independent directors, as defined in Section 57(o) of the 1940 Act, to approve an increase in our leverage capacity, and such approval would become effective after one year. In either case, we would be required to make certain disclosures on our website and in SEC filings regarding, among other things, the receipt of approval to increase our leverage, our leverage capacity and usage, and risks related to leverage.

Leverage magnifies the potential for loss on investments and on invested equity capital. As we use leverage to partially finance our investments, you will experience increased risks of investing in our securities. For example, as we increase our leverage and, as a result, our total interest expense and other required payments on such indebtedness, any decrease in our income would cause net investment income to decline more sharply than it would have had we not borrowed, and the decline could negatively affect our ability to make the required payments on such indebtedness or on our other securities. Increased leverage may also cause a downgrade of our credit rating. Leverage is generally considered a speculative investment technique.

All of our portfolio investments are recorded at fair value as determined in good faith by our board of directors, and, as a result, there is uncertainty as to the value of our portfolio investments and the valuation process for certain of our portfolio holdings creates a conflict of interest.

All of our portfolio investments take the form of debt and equity securities that are not publicly-traded. The debt and equity securities in which we invest for which market quotations are not readily available are valued at fair value as determined in good faith by our board of directors. As part of the valuation process, we may take into account the following types of factors, if relevant, in determining the fair value of our investments:

-15-

The fair value of each investment in our portfolio is determined quarterly by our board of directors. Any changes in fair value of portfolio securities from the prior period are recorded in our consolidated statement of operations as net change in unrealized appreciation or depreciation.

In connection with that determination, investment professionals from our investment advisor prepare portfolio company valuations based upon the most recent portfolio company financial statements available and projected financial results of each portfolio company. In addition, certain members of our board of directors have a pecuniary interest in our investment advisor. The participation of our investment advisor’s investment professionals in our valuation process, and the pecuniary interest in our investment advisor by certain members of our board of directors, may result in a conflict of interest as the management fees that we pay our investment advisor are based on our total assets (other than cash and cash equivalents but including assets purchased with borrowed amounts).

Our board of directors engages one or more independent valuation firm(s) to conduct independent appraisals of a selection of our portfolio investments for which market quotations are not readily available. Each portfolio company investment is generally appraised by the valuation firm(s) at least once every calendar year and each new portfolio company investment is appraised at least once in the twelve-month period following the initial investment. In certain instances, we may determine that it is not cost-effective, and as a result it is not in our stockholders’ best interest, to request the independent appraisal of certain portfolio company investments. Such instances include, but are not limited to, situations where we determine that the fair value of the portfolio company investment is relatively insignificant to the fair value of the total portfolio. Our board of directors consulted with the independent valuation firm(s) in arriving at our determination of fair value for 16 and 18 of our portfolio company investments representing 36.0% and 32.0% of the total portfolio investments at fair value (exclusive of new portfolio company investments made during the three months ended December 31, 2018 and 2017, respectively) as of December 31, 2018 and 2017, respectively.

Due to the inherent uncertainty of determining the fair value of investments that do not have a readily available market value, the fair value of our investments may differ significantly from the values that would have been used had a readily available market value existed for such investments, and the differences could be material. Declines in prices and liquidity in the corporate debt markets may also result in significant net unrealized depreciation in our debt portfolio. Our net asset value could be adversely affected if our determinations regarding the fair value of our investments were materially higher than the values that we ultimately realize upon the disposal of such investments.

We operate in a highly competitive market for investment opportunities, which could reduce returns and result in losses.

A number of entities compete with us to make the types of investments that we make. We compete with public and private funds, other BDCs, 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 of our 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. These characteristics could allow our competitors to consider a wider variety of investments, establish more relationships and offer better pricing and more flexible structuring than we offer. We may lose investment opportunities if we do not match our competitors’ pricing, terms and structure. If we match our competitors’ pricing, terms and structure, we may experience a decrease in net investment income or an increase in risk of capital loss. A significant part of our competitive advantage stems from the fact that the lower middle-market is underserved by traditional commercial and investment banks, and generally has less access to capital.

-16-

A significant increase in the number and/or the size of our competitors in this target market could force us to accept less attractive investment terms.

Furthermore, many of our competitors are not subject to the regulatory restrictions that the 1940 Act imposes on us as a BDC or the source of income, asset diversification and distribution requirements we must satisfy to maintain our RIC status. The competitive pressures we face may have a material adverse effect on our business, financial condition and results of operations. As a result of this existing and potentially increasing competition, we may not be able to take advantage of attractive investment opportunities from time to time, and we may not be able to identify and make investments that are consistent with our investment objective.

Our management and incentive fee structure may create incentives for our investment advisor that are not fully aligned with the interests of our stockholders and may encourage our investment advisor to make speculative investments.

The management and incentive fees paid to our investment advisor are based on our total assets (other than cash or cash equivalents but including assets purchased with borrowed amounts), and our investor advisor may therefore benefit when we incur debt or use leverage. This fee structure may encourage our investment advisor to cause us to borrow money to finance additional investments. Under certain circumstances, the use of borrowed money may increase the likelihood of default, which would disfavor our stockholders. Our board of directors is charged with protecting our interests by monitoring how our investment advisor addresses these and other conflicts of interests. Our board of directors is not expected to review or approve each borrowing or incurrence of leverage. 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 and must approve renewal of our Advisory Agreement.

The part of the incentive fee payable to our investment advisor that relates to our net investment income is computed and paid on income that includes interest income that has been accrued but not yet received in cash. This fee structure may encourage our investment advisor to favor debt financings that provide for deferred interest, rather than current cash payments of interest. Our investment advisor may have an incentive to invest in deferred interest securities in circumstances where it would not have done so but for the opportunity to continue to earn the incentive fee even when the issuers of the deferred interest securities would not be able to make actual cash payments to us on such securities. This risk could be increased because our investment advisor is not obligated to reimburse us for any incentive fees received even if we subsequently incur losses or never receive in cash the deferred interest that was previously accrued.

The incentive fee is based, in part, upon net capital gains realized on our investments. Unlike the portion of the incentive fee based on income, there is no hurdle rate applicable to the portion of the incentive fee based on net capital gains. As a result, our investment advisor may have a tendency to invest more capital in investments that are likely to result in capital gains as compared to income producing securities. Such a practice could result in our investing in more speculative securities than would otherwise be the case, which could result in higher investment losses, particularly during economic downturns.

We may be obligated to pay our investment advisor incentive compensation even if we incur a loss and may pay more than 20.0% of our net capital gains because we cannot recover payments made in previous years.

Our investment advisor will be entitled to incentive compensation for each fiscal quarter in an amount equal to a percentage of the excess of our pre-incentive fee net investment income for that quarter above a threshold return for that quarter. Our pre-incentive fee net investment income for incentive compensation purposes excludes realized and unrealized capital losses that we may incur in the fiscal quarter, even if such capital losses

-17-

result in a net loss on our consolidated statement of operations for that quarter. Thus, we may be required to pay our investment advisor incentive compensation for a fiscal quarter even if there is a decline in the value of our portfolio or we incur a net loss for that quarter. Further, if we pay an incentive fee of 20.0% of our realized capital gains (net of all realized capital losses and unrealized capital depreciation on a cumulative basis) and thereafter experience additional realized capital losses or unrealized capital depreciation, we will not be able to recover any portion of the incentive fee previously paid.

A general increase in interest rates will likely have the effect of making it easier for the investment advisor to receive incentive fees, without necessarily resulting in an increase in our net earnings.

Given the structure of the Investment Advisory Agreement, any general increase in interest rates can be expected to lead to higher interest rates applicable to our debt investments and will likely have the effect of making it easier for the investment advisor to meet the quarterly hurdle rate for payment of income incentive fees under the Investment Advisory Agreement without any additional increase in relative performance on the part of the investment advisor. This may occur without a corresponding increase in distributions to our stockholders. In addition, in view of the catch-up provision applicable to income incentive fees under the Investment Advisory Agreement, the investment advisor could potentially receive a significant portion of the increase in our investment income attributable to such a general increase in interest rates. If that were to occur, our increase in net earnings, if any, would likely be significantly smaller than the relative increase in the Adviser’s income incentive fee resulting from such a general increase in interest rates.

We may have potential conflicts of interest related to obligations that our investment advisor may have to other clients.

Currently, the Company, the Funds, Fidus Credit Opportunities, L.P. and Fidus Equity Opportunities Fund, L.P. are the only investment vehicles managed by our investment advisor. The Investment Advisory Agreement does not limit our investment advisor’s ability to act as an investment advisor to other funds, including other BDCs, or other investment advisory clients. To the extent our investment advisor acts as an investment advisor to other funds or clients, including Fidus Credit Opportunities, L.P. and Fidus Equity Opportunities Fund, L.P., we may have conflicts of interest with our investment advisor or its other clients that elect to invest in similar types of securities as those in which we invest. Members of our investment advisor’s investment committee serve or may serve as officers, directors or principals of entities that operate in the same or a related line of business as we do, or of investment funds or other investment vehicles managed by our investment advisor. In serving in these multiple capacities, they may have obligations to other clients or investors in those entities, the fulfillment of which may not be in the best interests of us or our stockholders. Our investment advisor will seek to allocate investment opportunities among eligible accounts in a manner that is fair and equitable over time and consistent with an allocation policy approved by our board of directors.

To the extent our investment advisor forms affiliates, including Fidus Credit Opportunities, L.P. and Fidus Equity Opportunities Fund, L.P., we may co-invest on a concurrent basis with such affiliates, subject to compliance with applicable regulations and regulatory guidance and our allocation procedures. While we may co-invest with investment entities managed by our investment advisor or its affiliates, to the extent permitted by the 1940 Act and the rules and regulations thereunder, the 1940 Act imposes significant limits on co-investment. On January 4, 2017, the SEC granted us relief sought in an exemptive application 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 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

-18-

with our investment objective and strategies. We intend to co-invest, subject to the conditions included in the Order.

Our investment advisor or its investment committee may, from time to time, possess material non-public information, limiting our investment discretion.

The investment professionals of our investment advisor may serve as directors of, or in a similar capacity with, companies in which we invest, the securities of which are purchased or sold on our behalf. In the event that material non-public information is obtained with respect to such companies, or we become subject to trading restrictions under the internal trading policies of those companies or as a result of applicable law or regulations, we could be prohibited for a period of time from purchasing or selling the securities of such companies, and this prohibition may have an adverse effect on us.

We may have conflicts related to other arrangements with our investment advisor.

We entered into a license agreement with Fidus Partners, LLC under which Fidus Partners, LLC granted 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.” Some of the members of our investment advisor’s investment committee and the senior origination professionals of our investment advisor are members of Fidus Partners, LLC. See “Management and Other Agreements—License Agreement.” In addition, we rent office space from our investment advisor and pay to our investment advisor our allocable portion of overhead and other expenses incurred in performing its obligations under the Administration Agreement, such as our allocable portion of the cost of our chief financial officer and chief compliance officer. This creates conflicts of interest that our board of directors must monitor.

The Funds are licensed by the SBA, and, therefore, are subject to SBA regulations.

The Funds are licensed to operate as SBICs and are regulated by the SBA. Under current SBA regulations, a licensed SBIC can provide capital to those entities that have a tangible net worth not exceeding $19.5 million and an average annual net income after U.S. federal income taxes not exceeding $6.5 million for the two most recent fiscal years. In addition, a licensed SBIC must devote 25.0% of its investment activity to those entities that have a tangible net worth not exceeding $6.0 million and an average annual net income after U.S. federal income taxes not exceeding $2.0 million for the two most recent fiscal years. The SBA regulations also provide alternative size standard criteria to determine eligibility, which depend on the industry in which the business is engaged and are based on either the number of employees or the gross sales of the business. The SBA regulations permit licensed SBICs to make long term loans to small businesses, invest in the equity securities of such businesses and provide them with consulting and advisory services. The SBA also places certain limitations on the financing terms of investments by SBICs in portfolio companies and prohibits SBICs from providing funds for certain purposes or to businesses in certain prohibited industries. Further, the SBA regulations require that a licensed SBIC be periodically examined and audited by the SBA staff to determine its compliance with the relevant SBA regulations. Compliance with these SBA requirements may cause the Funds to forego attractive investment opportunities that are not permitted under the SBA regulations, and may cause the Funds to make investments they otherwise would not make in order to remain in compliance with these regulations.

Failure to comply with the SBA regulations could result in the loss of the SBIC licenses and the resulting inability to participate in the SBA debenture program. The SBA 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 10.0% or more of a class of capital stock of a licensed SBIC. Current SBA regulations provide the SBA with certain rights and remedies if an SBIC violates their terms. A key regulatory metric for SBA is the extent of “Capital Impairment,” which is the extent of realized (and, in certain circumstances, net unrealized) losses compared with the SBIC’s private capital commitments. Interest payments, management fees, organization and other expenses are included in determining “realized losses.” SBA regulations preclude the full amount of “unrealized appreciation” from portfolio companies from being considered when calculating Capital Impairment

-19-

in certain circumstances. Remedies for regulatory violations are graduated in severity depending on the seriousness of Capital Impairment or other regulatory violations. For minor regulatory infractions, the SBA issues a warning. For more serious infractions, the use of SBA debentures may be limited or prohibited, outstanding debentures can be declared to be immediately due and payable, restrictions on distributions and making new investments may be imposed and management fees may be required to be reduced. In severe cases, the SBA may require the removal of a general partner of an SBIC or its officers, directors, managers or partners, or the SBA may obtain appointment of a receiver for the SBIC.

SBA regulations limit the amount of SBA-guaranteed debt that may be borrowed by an SBIC.

The SBA regulations currently limit the amount that is available to be borrowed by any SBIC and guaranteed by the SBA to 300.0% of an SBIC’s regulatory capital or $175.0 million, whichever is less. For three or more SBICs under common control, the maximum amount of outstanding SBA debentures cannot exceed $350.0 million. If the Funds borrow the maximum amount from the SBA and thereafter require additional capital, our cost of capital may increase, and there is no assurance that we will be able to obtain additional financing on acceptable terms.

Moreover, the Funds’ current status as SBICs does not automatically assure that they will continue to receive funding through the SBA debenture program. Receipt of SBA debenture funding is dependent upon the Funds’ continuing compliance with SBA regulations and policies and there being funding available. The amount of SBA debenture funding available to SBICs is dependent upon annual Congressional authorizations and in the future may be subject to annual Congressional appropriations. There can be no assurance that there will be sufficient SBA debenture funding available at the times desired by the Funds.

The debentures issued by the Funds and guaranteed by the SBA have a maturity of ten years and bear interest semi-annually at fixed rates. Certain of the Funds’ SBA debentures begin to mature in 2021 and will require repayment on or before the respective maturity dates. The Funds will need to generate sufficient cash flow to make required debt payments on such debentures. If the Funds are unable to generate such cash flow, the SBA, as guarantor of the debentures, will have a superior claim to our assets over our stockholders in the event the Funds liquidate or the SBA exercises its remedies under such debentures as the result of a default by the Funds.

The Funds, as SBICs, are limited in their ability to make distributions to us, which could result in us being unable to meet the minimum distribution requirements to maintain our status as a RIC.

In order to maintain our tax treatment as a RIC, we are required to distribute to our stockholders on an annual basis 90.0% of our net ordinary income and net short-term capital gains in excess of net long-term capital losses. For this purpose, our taxable income will include the income of the Funds (and any other entities that are disregarded as separate from us for U.S. federal income tax purposes). The Funds’ ability to make distributions to us may be limited by the Small Business Investment Act of 1958. As a result, in order to maintain our tax treatment as a RIC, we may be required to make distributions attributable to the Funds’ income without receiving any corresponding cash distributions with respect to such income. We can make no assurances that the Funds will be able to make, or not be limited in making, distributions to us. If we are unable to satisfy the annual distribution requirements, we may fail to maintain our tax treatment as a RIC, which would result in the imposition of corporate-level U.S. federal income tax on our entire taxable income without regard to any distributions made by us. See “We will be subject to corporate-level U.S. federal income tax if we are unable to maintain our tax treatment as a RIC under Subchapter M of the Code.”

Changes in interest rates will affect our cost of capital and net investment income.

Most of our debt investments bear interest at fixed rates and the value of these investments could be negatively affected by increases in market interest rates. In addition, to the extent that we borrow additional

-20-

funds to make investments, an increase in interest rates would make it more expensive for us to use debt to finance our investments. As a result, a significant increase in market interest rates could both reduce the value of our portfolio investments and increase our cost of capital, which would reduce our net investment income. Conversely, a decrease in interest rates may have an adverse impact on our returns by requiring us to seek lower yields on our debt investments and by increasing the risk that our portfolio companies will prepay the debt investments, resulting in the need to redeploy capital at potentially lower rates.

In July 2017, the head of the United Kingdom Financial Conduct Authority announced the desire to phase out the use of London Interbank Offered Rate (“LIBOR”) by the end of 2021. There is currently no definitive information regarding the future utilization of LIBOR or of any particular replacement rate. As such, the potential effect of any such event on our cost of capital and net investment income cannot yet be determined. In addition, any further changes or reforms to the determination or supervision of LIBOR may result in a sudden or prolonged increase or decrease in reported LIBOR, which could have an adverse impact on the market value for or value of any LIBOR-linked securities, loans, and other financial obligations or extensions of credit held by or due to us and could have a material adverse effect on our business, financial condition and results of operations.

You should also be aware that a rise in market interest rates typically leads to higher interest rates applicable to our debt investments. Accordingly, an increase in interest rates may result in an increase of the amount of incentive fees payable to our investment advisor.

Our ability to enter into transactions involving derivatives and financial commitment transactions may be limited.

The SEC has proposed a new rule under the 1940 Act that would govern the use of derivatives (defined to include any swap, security-based swap, futures contract, forward contract, option or any similar instrument) as well as financial commitment transactions (defined to include reverse repurchase agreements, short sale borrowings and any firm or standby commitment agreement or similar agreement) by BDCs. Under the proposed rule, a BDC would be required to comply with one of two alternative portfolio limitations and manage the risks associated with derivatives transactions and financial commitment transactions by segregating certain assets. Furthermore, a BDC that engages in more than a limited amount of derivatives transactions or that uses complex derivatives would be required to establish a formalized derivatives risk management program. If the SEC adopts this rule in the form proposed, our ability to enter into transactions involving such instruments may be hindered, which could have an adverse effect on our business, financial condition and results of operations.

Global economic, political and market conditions may adversely affect our business, results of operations and financial condition, including our revenue growth and profitability.

The current worldwide financial market situation, as well as various social and political tensions in the United States and around the world, may contribute to increased market volatility, may have long-term effects on the U.S. and worldwide financial markets, and may cause economic uncertainties or deterioration in the United States and worldwide. The U.S. and global capital markets experienced extreme volatility and disruption during the economic downturn that began in mid-2007, and the U.S. economy was in a recession for several consecutive calendar quarters during the same period. In 2010, a financial crisis emerged in Europe, triggered by high budget deficits and rising direct and contingent sovereign debt, which created concerns about the ability of certain nations to continue to service their sovereign debt obligations. Risks resulting from such debt crisis, including any austerity measures taken in exchange for bailout of certain nations, and any future debt crisis in Europe or any similar crisis elsewhere could have a detrimental impact on the global economic recovery, sovereign and non-sovereign debt in certain countries and the financial condition of financial institutions generally. In June 2016, the United Kingdom held a referendum in which voters approved an exit from the European Union (“Brexit”), and, subsequently, on March 29, 2017, the U.K. government began the formal process of leaving the European Union, which is currently set to occur on March 29, 2019. Because the U.K. Parliament rejected Prime Minister Theresa May’s proposed Brexit deal with the European Union in January 2019, there is increased

-21-

uncertainty on the final outcome of Brexit. Brexit has created political and economic uncertainty and instability in the global markets (including currency and credit markets) and especially in the United Kingdom and European Union, and this uncertainty and instability may last indefinitely. The implications of the United Kingdom’s pending withdrawal from the European Union are unclear at present. There is continued concern about national-level support for the Euro and the accompanying coordination of fiscal and wage policy among European Economic and Monetary Union member countries. In addition, the fiscal and monetary policies of foreign nations, such as Russia and China, may have a severe impact on the worldwide and U.S. financial markets.

The current state of the economy and financial markets of the U.S., United Kingdom, China and other several countries in the European Union increases the likelihood of adverse effects on our financial position and results of operations.

Due to federal budget deficit concerns, S&P downgraded the federal government’s credit rating from AAA to AA+ for the first time in history on August 5, 2011. Further downgrades or warnings by S&P or other rating agencies, and the U.S. government’s credit and deficit concerns in general, could cause interest rates and borrowing costs to rise, which may negatively impact both the perception of credit risk associated with our debt portfolio and our ability to access the debt markets on favorable terms. In addition, a decreased U.S. government credit rating could create broader financial turmoil and uncertainty, which may weigh heavily on our financial performance and the value of our common stock.

In 2010, a financial crisis emerged in Europe, triggered by high budget deficits and rising direct and contingent sovereign debt, which created concerns about the ability of certain nations to continue to service their sovereign debt obligations. Risks resulting from such debt crisis and any future debt crisis in Europe or any similar crisis elsewhere could have a detrimental impact on the global economic recovery, sovereign and non-sovereign debt in certain countries and the financial condition of financial institutions generally.

In the second quarter of 2015, stock prices in China experienced a significant drop, resulting primarily from continued selloff of shares trading in Chinese markets. In addition, in August 2015, Chinese authorities sharply devalued China’s currency. Since then, the Chinese capital markets have continued to experience periods of instability. In June 2016, British voters passed a referendum to exit the European Union leading to heightened volatility in global markets and foreign currencies. These market and economic disruptions have affected, and may in the future affect, the U.S. capital markets, which could adversely affect our business, financial condition or results of operations.

In October 2014, the Federal Reserve announced that it was concluding its bond-buying program, or quantitative easing, which was designed to stimulate the economy and expand the Federal Reserve’s holdings of long-term securities, suggesting that key economic indicators, such as the unemployment rate, had showed signs of improvement since the inception of the program. It is unclear what effect, if any, the conclusion of the Federal Reserve’s bond-buying program will have on the value of our investments. Additionally, since December 2015, the Federal Reserve has continued to raise the Federal Funds Rate and has announced its intention to continue to raise the federal funds rate over time. These developments, along with the U.S. government’s credit and deficit concerns, the European sovereign debt crisis and the economic slowdown in China, could cause interest rates and borrowing costs to rise, which may negatively impact our ability to access the debt markets on favorable terms.

We may experience fluctuations in our quarterly operating results.

We could experience fluctuations in our quarterly operating results due to a number of factors, including our ability or inability to make investments in companies that meet our investment criteria, the interest rate payable on the debt securities we acquire, the default rate on such securities, the level of our expenses, variations in and the timing of the recognition of realized and unrealized gains or losses, the degree to which we encounter competition in our markets and general economic conditions. As a result of these factors, results for any period should not be relied upon as being indicative of performance in future periods.

We will be subject to corporate-level U.S. federal income tax if we are unable to maintain our tax treatment as a RIC under Subchapter M of the Code.

We have elected to be treated as a RIC under Subchapter M of the Code; however, no assurance can be given that we will be able to maintain our RIC tax treatment. To maintain our tax treatment as a RIC under Subchapter M of the Code and to avoid the imposition of U.S. federal income taxes on income and gains distributed to our stockholders, we must meet certain requirements, including source-of-income, asset diversification and annual distribution requirements. The source-of-income requirement will be satisfied if we derive at least 90.0% of our gross income for each year from dividends, interest, gains from sale of securities or similar sources. To maintain our tax treatment as a RIC, we must also meet certain asset diversification requirements at the end of each calendar quarter. Failure to meet these requirements may result in our losing our RIC tax treatment or our having to dispose of certain investments quickly in order to prevent the loss of RIC tax treatment. Because most of our investments will be in private or thinly traded public companies, any such dispositions could be made at disadvantageous prices and may result in substantial losses. The annual distribution requirement applicable to RICs will be satisfied if we distribute at least 90.0% of our net ordinary income and net short-term capital gains in excess of net long-term capital losses, if any, to our stockholders on an annual basis. In addition, we will be subject to a 4.0% nondeductible federal excise tax to the extent that we do not satisfy certain additional minimum distribution requirements on a calendar-year basis. We will be subject, to the extent we use debt financing, to certain asset coverage ratio requirements under the 1940 Act and financial covenants under loan and credit agreements that could, under certain circumstances, restrict us from making annual distributions necessary to maintain our tax treatment as a RIC. If we are unable to obtain cash from other sources, we may fail to maintain our tax treatment as a RIC and, thus, may be subject to U.S. federal corporate income tax on our entire taxable income without regard to any distributions made by us. If we fail to maintain our tax treatment as a RIC for any reason and become subject to U.S. corporate income tax, the resulting tax liability could substantially reduce our net assets, the amount of income available for distributions to stockholders and the amount of our distributions and the amount of funds available for new investments. Such a failure could have a material adverse effect on us and our stockholders.

We may not be able to pay you distributions, our distributions may not grow over time, a portion of distributions paid to you may be a return of capital, and investors in our debt securities may not receive all of the interest income to which they are entitled.

We intend to make distributions on a quarterly basis to our stockholders out of assets legally available for distribution. We cannot assure you that we will achieve investment results that will allow us to make a specified level of cash distributions or year-to-year increases in cash distributions. Our ability to pay distributions might be adversely affected by the impact of one or more of the risk factors described in this annual report on Form 10-K. In addition, due to the asset coverage test applicable to us as a BDC, in the future, we may be limited in our ability to make distributions. All distributions will be made at the discretion of our board of directors and will depend on our earnings, our financial condition, maintenance of RIC tax treatment, compliance with applicable BDC regulations, SBA regulations, state corporate laws affecting the distribution of corporate assets and such other factors as our board of directors may deem relevant from time to time. We cannot assure you that we will make distributions to our stockholders in the future.

If we issue debt securities in the future, the above-referenced restrictions on distributions may also inhibit our ability to make required interest payments to holders of any such debt securities, which may cause a default under the terms of our then-existing debt agreements. Such a default could materially increase our cost of raising capital, as well as cause us to incur penalties under the terms of our then-existing debt agreements.

When we make quarterly distributions, we will be required to determine the extent to which such distributions are paid out of current and accumulated earnings and profits, recognized capital gain or capital. To the extent there is a return of capital, an investor gets his or her own invested capital returned to him or her, but reduced by the amount of the Company’s expenses and any sales load he or she may have paid. In addition, investors will be required to reduce their basis in our stock for U.S. federal income tax purposes.

-23-

We may have difficulty paying our required distributions if we recognize income before, or without, receiving cash representing such income.

For U.S. federal income tax purposes, we are required to include in our income certain amounts that we have not yet received in cash, such as OID, which may arise if we receive warrants in connection with the making of a loan or in other circumstances, and contractual PIK interest, which represents contractual interest added to the loan balance and due at the end of the loan term. Such OID, or increases in loan balances as a result of contracted PIK arrangements, will be included in our income before we receive any corresponding cash payments. We also may be required to include in our income certain other amounts that we will not receive in cash.

Since in certain cases we may be required to recognize income before or without receiving cash representing such income, we may have difficulty meeting the requirement to distribute on an annual basis at least 90.0% of our net ordinary income and net short-term capital gains in excess of net long-term capital losses, if any, to maintain our tax treatment as a RIC. In such a case, 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 to satisfy the annual distribution requirements. In such circumstances, if we are unable to obtain such cash from other sources, we may fail to maintain our tax treatment as a RIC and thus be subject to corporate-level U.S. federal income tax. See “We will be subject to corporate-level U.S. federal income tax if we are unable to maintain our tax treatment as a RIC under Subchapter M of the Code.”

If a portfolio company defaults on a loan that is structured to provide accrued interest, it is possible that accrued interest previously used in the calculation of the incentive fee will become uncollectible. Our investment advisor will not be under any obligation to reimburse us for any part of the incentive fee it received that was based on accrued income that we never receive as a result of a default by an entity on the obligation that resulted in the accrual of such income. That part of the incentive fee payable by us that relates to our net investment income will be computed and paid on income that may include interest that has been accrued but not yet received in cash, such as market discount, debt instruments with PIK interest, preferred stock with PIK dividends and zero coupon securities.

To the extent the we invest in OID instruments, including PIK loans, zero coupon bonds, and debt securities with attached warrants, investors will be exposed to the risks associated with the inclusion of such non-cash income in taxable and accounting income prior to receipt of cash, including the following risks:

-24-

You may have a current tax liability on distributions you elect to reinvest in our common stock but would not receive cash to pay such tax liability.

If you participate in our dividend reinvestment plan, you will be deemed to have received, and for U.S. federal income tax purposes will be taxed on, the amount reinvested in our common stock to the extent the amount reinvested was not a tax-free return of capital. As a result, unless you are a tax-exempt entity, you may have to use funds from other sources to pay your tax liability on the value of our common stock received as a result of the distribution.

Because we expect to distribute substantially all of our net investment income and net realized capital gains to our stockholders, we will need additional capital to finance our growth, and such capital may not be available on favorable terms or at all.

We have elected to be taxed for U.S. federal income tax purposes as a RIC under Subchapter M of the Code. If we continue to meet certain requirements, including source-of-income, asset diversification and distribution requirements, and if we continue to be regulated as a BDC, we will continue to qualify to be taxed as a RIC and therefore will not have to pay U.S. federal corporate income tax on income that we timely distribute to our stockholders, allowing us to substantially reduce or eliminate our corporate-level income tax liability. As a BDC, we are generally required to meet a coverage ratio of total assets to total senior securities, which includes all of our borrowings (other than SBA leverage) and any preferred stock we may issue in the future, of at least 200.0% at the time we issue any debt or preferred stock. This requirement limits the amount of our leverage. Because we will continue to need capital to grow our investment portfolio, this limitation may prevent us from incurring debt or issuing preferred stock and require us to raise additional equity at a time when it may be disadvantageous to do so.

While we expect to be able to borrow and to issue additional debt and equity securities, we cannot assure you that debt and equity financing will be available to us on favorable terms, or at all. If additional funds are not available to us, we could be forced to curtail or cease new investment activities, and our net asset value could decline. In addition, as a BDC, we generally are not permitted to issue equity securities priced below net asset value without stockholder approval. At our Annual Stockholders Meeting on June 7, 2018, our stockholders voted to allow us to issue common stock at a price below net asset value per share for a period of one year ending on the earlier of June 7, 2019 or the date of our 2019 Annual Meeting of Stockholders. We expect to present to our stockholders a similar proposal at our 2019 Annual Meeting of Stockholders. The maximum number of shares issuable below net asset value pursuant to the authority granted by our stockholders that could result in such dilution is limited to 25.0% of FIC’s then outstanding common stock immediately prior to each such sale. We do not intend to issue shares of our common stock below net asset value unless our board of directors determines that it would be in our stockholders’ best interests to do so. The level of net asset value dilution that could result from such an offering is not limited.

Illustration: Examples of Dilutive Effect of the Issuance of Shares Below Net Asset Value. The following table illustrates the level of net asset value dilution that would be experienced by a nonparticipating stockholder in three different hypothetical offerings of different sizes and levels of discount from net asset value 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.

-25-

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 net asset value and net asset value per share are thus $10,000,000 and $10.00, respectively. The table illustrates the dilutive effect on nonparticipating Stockholder A of (1) an offering of 50,000 shares (5.0% of the outstanding shares) at $9.50 per share after offering expenses and commission (a 5.0% discount from net asset value), (2) an offering of 100,000 shares (10.0% of the outstanding shares) at $9.00 per share after offering expenses and commissions (a 10.0% discount from net asset value) and (3) an offering of 200,000 shares (20.0% of the outstanding shares) at $8.00 per share after offering expenses and commissions (a 20.0% discount from net asset value). The acronym “NAV” stands for “net asset value.”

In any offering of common stock, we will present the actual dilution to stockholders in tabular form in the prospectus supplement specific to that offering.

Our board of directors may change our investment objective, operating policies and strategies without prior notice or stockholder approval, the effects of which may be adverse.

Our board of directors has the authority, except as otherwise provided by the 1940 Act, to modify or waive certain of our operating policies and strategies without prior notice and without stockholder approval. Under Maryland law, we also cannot be dissolved without prior stockholder approval except by judicial action. In addition, upon approval of a majority of our stockholders, we may elect to withdraw our status as a BDC. If we, or Fund I, decide to withdraw our election, or if we otherwise fail to maintain our qualification, as a BDC, we may be subject to the substantially greater regulation under the 1940 Act as a

-26-

closed-end investment company. Compliance with such regulations would significantly decrease our operating flexibility, and could significantly increase our costs of doing business. We cannot predict the effect any changes to our current operating policies and strategies would have on our business, operating results or the value of our common stock. Nevertheless, any such changes could adversely affect our business and impair our ability to make distributions.

Regulations governing our operation as a BDC affect our ability to raise, and the way in which we raise, additional capital which may have a negative effect on our growth.

Our business will require capital to operate and grow. We may acquire such additional capital from the following sources:

Senior Securities. Currently we, through the Funds, issue debt securities guaranteed by the SBA and have access to funds under a revolving credit facility. In the future, we may issue debt securities or preferred stock and/or borrow money from banks or other financial institutions, which we refer to collectively as senior securities. As a result of issuing senior securities, we will be exposed to additional risks, including, but not limited to, the following:

Additional Common Stock. Under the provisions of the 1940 Act, we are not generally able to issue and sell our common stock at a price below net asset value per share. We may, however, sell our common stock, warrants, options or rights to acquire our common stock, at a price below the current net asset value of the common stock if our board of directors determines that such sale is in the best interests of our stockholders, and our stockholders approve such sale. At our Annual Stockholders Meeting on June 7, 2018, our stockholders voted to allow us to issue common stock at a price below net asset value per share for a period of one year ending on the earlier of June 7, 2019 or the date of our 2019 Annual Meeting of Stockholders. We expect to present to our stockholders a similar proposal at our 2019 Annual Meeting of Stockholders. The maximum number of shares issuable below net asset value pursuant to the authority granted by our stockholders that could result in such dilution is limited to 25.0% of FIC’s then outstanding common stock immediately prior to each such sale. We do not intend to sell or otherwise issue shares of our common stock below net asset value unless our board of directors determines that it would be in our stockholders’ best interests to do so. The level of net asset value

-27-

dilution that could result from such an offering is not limited. In any such case, however, the price at which our common stock is to be issued and sold may not be less than a price which, in the determination of our board of directors, closely approximates the market value of such securities (less any distributing commission or discount). We may also make rights offerings to our stockholders at prices per share less than the net asset value per share, subject to applicable requirements of the 1940 Act and the regulations and staff interpretations thereunder. If we raise additional funds by issuing more common stock or senior securities convertible into, or exchangeable for, our common stock, the percentage ownership of our stockholders at that time would decrease, and they may experience dilution. Moreover, we can offer no assurance that we will be able to issue and sell additional equity securities in the future, on favorable terms or at all.

The U.S. Presidential Administration may make substantial changes to financial regulation, as well as fiscal and tax policies that may adversely affect our business.

The Republican Party currently controls the executive branch and the senate portion of the legislative branch of government, which increases the likelihood that legislation may be adopted that could significantly affect the regulation of U.S. financial markets. Areas subject to potential change, amendment or repeal include the Wall Street Reform and Consumer protection Act of 2010 (“Dodd-Frank Act”) and the authority of the Federal Reserve and the Financial Stability Oversight Council. For example, in March 2018 the U.S. Senate passed a bill that eased financial regulations and reduced oversight for certain entities. The United States may also potentially withdraw from or renegotiate various trade agreements and take other actions that would change current trade policies of the United States. We cannot predict which, if any, of these actions will be taken or, if taken, their effect on the financial stability of the United States. Such actions could have a significant adverse effect on our business, financial condition and results of operations. We cannot predict the effects of these or similar events in the future on the U.S. economy and securities markets or on our investments. We monitor developments and seek to manage our investments in a manner consistent with achieving our investment objective, but there can be no assurance that we will be successful in doing so.

On May 24, 2018, the U.S. presidential administration signed into law the Economic Growth, Regulatory Relief, and Consumer Protection Act, which increased from $50 billion to $250 billion the asset threshold for designation of “systemically important financial institutions” or “SIFIs” subject to enhanced prudential standards set by the Federal Reserve Board, staggering application of this change based on the size and risk of the covered bank holding company. On May 30, 2018, the Federal Reserve Board voted to consider changes to the Volcker Rule that would loosen compliance requirements for all banks. The effect of this change and any further rules or regulations are and could be complex and far-reaching, and the change and any future laws or regulations or changes thereto could negatively impact our operations, cash flows or financial condition, impose additional costs on us, intensify the regulatory supervision of us or otherwise adversely affect our business, financial condition and results of operations.

Uncertainty about U.S. Presidential Administration initiatives could negatively impact our business, financial condition and results of operations.

The current administration has called for significant changes to U.S. trade, healthcare, immigration, foreign and government regulatory policy. In this regard, there is significant uncertainty with respect to legislation, regulation and government policy at the federal level, as well as the state and local levels. Recent events have created a climate of heightened uncertainty and introduced new and difficult-to-quantify macroeconomic and political risks with potentially far-reaching implications. There has been a corresponding meaningful increase in the uncertainty surrounding interest rates, inflation, foreign exchange rates, trade volumes and fiscal and monetary policy. To the extent the U.S. Congress or the current administration implements changes to U.S. policy, those changes may impact, among other things, the U.S. and global economy, international trade and relations, unemployment, immigration, corporate taxes, healthcare, the U.S. regulatory environment, inflation and other areas. Although we cannot predict the impact, if any, of these changes to our business, they could adversely affect our business, financial condition, operating results and cash flows. Until we know what policy

-28-

changes are made and how those changes impact our business and the business of our competitors over the long term, we will not know if, overall, we will benefit from them or be negatively affected by them.

Recent tax legislation could have a negative effect on the Company.

On December 22, 2017, tax reform legislation commonly referred to as the Tax Cuts and Jobs Act was signed into law. This legislation makes significant changes to the U.S. federal income tax rules applicable to both individuals and entities, including permanently reducing the U.S. federal corporate income tax rate, reducing the maximum U.S. federal individual income tax rate (effective for taxable years 2018 through 2025), restricting the deductibility of interest expense, and changing the rules regarding the calculation of net operating loss deductions that may be used to offset taxable income. There is uncertainty as to the impact of this legislation on us, the entities in which we invest, or an investment in our securities. New legislation and any U.S. Treasury regulations, administrative interpretations or court decisions interpreting such legislation could significantly and negatively affect the Company’s ability to qualify for tax treatment as a RIC or the U.S. federal income tax consequences to the Company and its investors of such qualification, or could have other adverse consequences. You are urged to consult with your tax advisor with respect to the impact of this legislation and the status of any other regulatory or administrative developments and proposals and their potential effect on your investment in our securities.

Changes in laws or regulations governing our operations may adversely affect our business or cause us to alter our business strategy.

We are subject to regulation at the local, state and federal level. New legislation may be enacted or new interpretations, rulings or regulations could be adopted, including those governing the types of investments we are permitted to make, any of which could harm us and our stockholders, potentially with retroactive effect. In addition, any change to the SBA’s current debenture program could have a significant impact on our ability to obtain low-cost leverage and, therefore, our competitive advantage over other funds.

Legal, tax and regulatory changes could occur that may adversely affect us. For example, from time to time the market for private equity transactions has been (and is currently being) adversely affected by a decrease in the availability of senior and subordinated financings for transactions, in part in response to credit market disruptions and/or regulatory pressures on providers of financing to reduce or eliminate their exposure to the risks involved in such transactions.

Additionally, any changes to the laws and regulations governing our operations related to permitted investments may cause us to alter our investment strategy in order to meet our investment objectives. Such changes could result in material differences to the strategies and plans set forth in this Annual Report and may shift our investment focus from the areas of expertise of our investment advisor to other types of investments in which our investment advisor may have little or no expertise or experience. Any such changes, if they occur, could have a material adverse effect on our results of operations and the value of your investment.

Changes to U.S. tariff and import/export regulations may have a negative effect on our portfolio companies and, in turn, harm us.

There has been ongoing discussion and commentary regarding potential significant changes to U.S. trade policies, treaties and tariffs. The current U.S. presidential administration, along with the U.S. Congress, has created significant uncertainty about the future relationship between the United States and other countries with respect to trade policies, treaties and tariffs. These developments, or the perception that any of them could occur, may have a material adverse effect on global economic conditions and the stability of global financial markets, and may significantly reduce global trade and, in particular, trade between the impacted nations and the United States. Any of these factors could depress economic activity and restrict our portfolio companies’ access to suppliers or customers and have a material adverse effect on their business, financial condition and results of operations, which in turn would negatively impact us.

-29-

Our ability to enter into and exit investment transactions with our affiliates will be restricted.

Except in those instances where we have received prior exemptive relief from the SEC, we will be prohibited under the 1940 Act from knowingly participating in certain transactions with our affiliates without the prior approval of our Independent Directors. We, our investment advisor, the Funds, and Fidus Credit Opportunities, L.P. received exemptive relief from the SEC under the 1940 Act, which permits us to co-invest with other funds managed by our investment advisor or its affiliates in a manner consistent with our investment objective, positions, policies, strategies and restrictions as well as regulatory requirements and other pertinent factors. In addition, any person that owns, directly or indirectly, 5.0% or more of our outstanding voting securities is deemed our affiliate for purposes of the 1940 Act and we are generally prohibited from buying or selling any security from or to such affiliate, absent the prior approval of our Independent Directors. The 1940 Act also prohibits “joint” transactions with an affiliate, which could include investments in the same portfolio company (whether at the same or different times), without prior approval of our Independent Directors. If a person acquires more than 25.0% of our voting securities, we will be prohibited from buying or selling any security from or to such person, or entering into joint transactions with such person, absent the prior approval of the SEC. These restrictions could limit or prohibit us from making certain attractive investments that we might otherwise make absent such restrictions.

Our investment advisor can resign on 60 days’ notice, and we may not be able to find a suitable replacement within that time, resulting in a disruption in our operations that could adversely affect our financial condition, business and results of operations.

Our investment advisor has the right, under the Investment Advisory Agreement, to resign at any time upon not less than 60 days’ written notice, whether we have found a replacement or not. If our investment advisor resigns, we may not be able to find a new investment advisor and administrator or hire internal management with similar expertise and ability to provide the same or equivalent services on acceptable terms within 60 days, or at all. If we are unable to do so quickly, our operations are likely to experience a disruption, our financial condition, business and results of operations as well as our ability to pay distributions are likely to be adversely affected and the market price of our shares may decline. In addition, investment activities are likely to suffer if we are unable to identify and reach an agreement with a single institution or group of executives having the expertise possessed by our investment advisor and its affiliates. Even if we are able to retain comparable management, whether internal or external, the integration of such management and their lack of familiarity with our investment objective may result in additional costs and time delays that may adversely affect our financial condition, business and results of operations.

Our investment advisor can resign from its role as our administrator under the Administration Agreement, and we may not be able to find a suitable replacement, resulting in a disruption in our operations that could adversely affect our financial condition, business and results of operations.

Our investment advisor also has the right to resign under the Administration Agreement, whether we have found a replacement or not. If our investment advisor resigns as our administrator, we may not be able to find a new administrator or hire internal management with similar expertise and ability to provide the same or equivalent services on acceptable terms, or at all. If we are unable to do so quickly, our operations are likely to experience a disruption, our financial condition, business and results of operations as well as our ability to pay distributions are likely to be adversely affected and the market price of our shares may decline. In addition, administrative activities are likely to suffer if we are unable to identify and reach an agreement with a service provider or individuals with the expertise possessed by our investment advisor. Even if we are able to retain a comparable service provider or individuals to perform such services, whether internal or external, their integration into our business and lack of familiarity with our investment objective may result in additional costs and time delays that may adversely affect our financial condition, business and results of operations.

Efforts to comply with the Sarbanes-Oxley Act will involve significant expenditures, and non-compliance with the Sarbanes-Oxley Act may adversely affect us and the market price of our common stock.

As a publicly-traded company, we incur legal, accounting and other expenses, including costs associated with the periodic reporting requirements applicable to a company whose securities are registered under the Exchange Act, as well as additional corporate governance requirements, including requirements under the Sarbanes-Oxley Act and other rules implemented by the SEC.

Section 404 of the Sarbanes-Oxley Act requires that public companies evaluate and report on their systems of internal control over financial reporting. In addition, our independent registered public accounting firm must report on management’s evaluation of those controls. In future periods, we may identify deficiencies in our system of internal controls over financial reporting that may require remediation. There can be no assurances that any such future deficiencies identified may not be material weaknesses that would be required to be reported in future periods.

Internal and external cyber threats, as well as other disasters, could impair our ability to conduct business effectively.

The occurrence of a disaster, such as a cyber-attack against us or against a third-party that has access to our data or networks, a natural catastrophe, an industrial accident, failure of our disaster recovery systems, or consequential employee error, could have an adverse effect on our ability to communicate or conduct business, negatively impacting our operations and financial condition. This adverse effect can become particularly acute if those events affect our electronic data processing, transmission, storage, and retrieval systems, or impact the availability, integrity, or confidentiality of our data.

We depend heavily upon computer systems to perform necessary business functions. Despite our implementation of a variety of security measures, our computer systems, networks, and data, like those of other companies, could be subject to cyber-attacks and unauthorized access, use, alteration, or destruction, such as from physical and electronic break-ins or unauthorized tampering, malware and computer virus attacks, or system failures and disruptions. If one or more of these events occurs, it could potentially jeopardize the confidential, proprietary, and other information processed, stored in, and transmitted through our computer systems and networks. Such an attack could cause interruptions or malfunctions in our operations, which could result in financial losses, litigation, regulatory penalties, client dissatisfaction or loss, reputational damage, and increased costs associated with mitigation of damages and remediation.

Third parties with which we do business may also be sources of cybersecurity or other technological risk. We outsource certain functions and these relationships allow for the storage and processing of our information, as well as client, counterparty, employee, and borrower information. While we engage in actions to reduce our exposure resulting from outsourcing, ongoing threats may result in unauthorized access, loss, exposure, destruction, or other cybersecurity incident that affects our data, resulting in increased costs and other consequences as described above.

Risks Relating to Our Investments

Economic recessions or downturns could impair our portfolio companies and harm our operating results.

Many of our portfolio companies are susceptible to economic slowdowns or recessions (including industry specific downturns) and may be unable to repay our debt investments during these periods. Therefore, our non-performing assets are likely to increase and the value of our portfolio is likely to decrease during these periods. Adverse economic conditions may decrease the value of collateral securing some of our debt investments and the value of our equity investments. Economic slowdowns or recessions could lead to financial losses in our portfolio and a decrease in revenues, net income and assets. Unfavorable economic conditions also could increase our funding costs, limit our access to the capital markets or result in a decision by lenders not to extend credit to us. These events could prevent us from increasing our investments and harm our operating results.

-31-

A portfolio company’s failure to satisfy financial or operating covenants imposed by us or other lenders could lead to defaults and, potentially, termination of its loans and foreclosure on its assets, which could trigger cross-defaults under other agreements and jeopardize our portfolio company’s ability to meet its obligations under the loans and debt securities that we hold. We may incur expenses to the extent necessary to seek recovery upon default or to negotiate new terms with a defaulting portfolio company.

Terrorist attacks, acts of war, or natural disasters may affect any market for our common stock, impact the businesses in which we invest and harm our business, operating results and financial condition.

Portfolio investments may be affected by force majeure events (i.e., events beyond the control of the party claiming that the event has occurred, including, without limitation, acts of God, fire, flood, earthquakes, war, terrorism and labor strikes). Some force majeure events may adversely affect the ability of a party (including a portfolio company or a counterparty to us or a portfolio company) to perform its obligations until it is able to remedy the force majeure event. In addition, the cost to a portfolio company of repairing or replacing damaged assets resulting from such force majeure event could be considerable. Additionally, a major governmental intervention into industry, including the nationalization of an industry or the assertion of control over one or more companies or its assets, could result in a loss to us, including if its investment in such issuer is cancelled, unwound or acquired (which could be without what we consider to be adequate compensation). To the extent we are exposed to investments in portfolio companies that as a group are exposed to such force majeure events, the risks and potential losses to us are enhanced.

Our investments in certain industry sectors, such as the energy sector, may be subject to significant political, economic and capacity risks that may increase the possibility that we lose all or a part of our investment.

The revenues and profitability of certain portfolio companies may be significantly affected by the future prices of and the demand for oil, natural gas liquids and natural gas, which are inherently uncertain. Investments in energy companies may have significant shortfalls in projected cash flow if prices decline from levels projected at the time the investment is made. Various factors beyond our control could affect energy prices, including worldwide supplies, political instability or armed conflicts in oil, natural gas liquids and natural gas producing regions, the price of foreign imports, the level of consumer demand, the price and availability of alternative fuels, capacity constraints and changes in existing government regulation, taxation and price controls. Energy prices have fluctuated greatly during the past, and energy markets continue to be volatile.

Changes in healthcare laws and other regulations applicable to some of our portfolio companies’ businesses may constrain their ability to offer their products and services.

Changes in healthcare or other laws and regulations applicable to the businesses of some of our portfolio companies may occur that could increase their compliance and other costs of doing business, require significant systems enhancements, or render their products or services less profitable or obsolete, any of which could have a material adverse effect on their results of operations. There has also been an increased political and regulatory focus on healthcare laws in recent years, and new legislation could have a material effect on the business and operations of some of our portfolio companies.

If our portfolio companies are unable to protect their intellectual property rights, our business and prospects could be harmed, and if portfolio companies are required to devote significant resources to protecting their intellectual property rights, the value of our investment could be reduced.

Our future success and competitive position will depend in part upon the ability of our portfolio companies to obtain, maintain and protect proprietary technology used in their products and services. The intellectual property held by our portfolio companies often represents a substantial portion of the collateral securing our investments and/or constitutes a significant portion of the portfolio companies’ value and may be available in a downside scenario to repay our loans. Our portfolio companies will rely, in part, on patent, trade secret, and trademark law to protect that technology, but competitors may misappropriate their intellectual property, and

-32-

disputes as to ownership of intellectual property may arise. Portfolio companies may, from time to time, be required to institute litigation to enforce their patents, copyrights, or other intellectual property rights; protect their trade secrets; determine the validity and scope of the proprietary rights of others; or defend against claims of infringement. Such litigation could result in substantial costs and diversion of resources. Similarly, if a portfolio company is found to infringe or misappropriate a third-party’s patent or other proprietary rights, it could be required to pay damages to the third party, alter its products or processes, obtain a license from the third-party, and/or cease activities utilizing the proprietary rights, including making or selling products utilizing the proprietary rights. Any of the foregoing events could negatively affect both the portfolio company’s ability to service our debt investment and the value of any related debt and equity securities that we own, as well as any collateral securing our investment.

Our investments in portfolio companies may be risky, and we could lose all or part of our investment.

Investing in lower middle-market companies involves a number of significant risks. Among other things, these companies:

In addition, in the course of providing significant managerial assistance to certain portfolio companies, certain of our management and directors may serve as directors on the boards of such companies. To the extent that litigation arises out of investments in these portfolio companies, our management and directors may be named as defendants in such litigation, which could result in an expenditure of funds (through our indemnification of such officers and directors) and the diversion of management time and resources.

The lack of liquidity in our investments may adversely affect our business.

All of our assets may be invested in illiquid securities, and a substantial portion of our investments in leveraged companies will be subject to legal and other restrictions on resale or will otherwise be less liquid than more broadly traded public securities. The illiquidity of these investments may make it difficult for us to sell such investments when desired. In addition, if we are required to liquidate all or a portion of our portfolio quickly, we may realize significantly less than the value at which we have previously recorded these investments. As a result, we do not expect to achieve liquidity in our investments in the near-term. However, to maintain the elections to be regulated as a BDC and as a RIC, we may have to dispose of investments if they do not satisfy one or more of the applicable criteria under the respective regulatory frameworks. We may also face other restrictions on our ability to liquidate an investment in a portfolio company to the extent that we or our investment advisor have material nonpublic information regarding such portfolio company.

-33-

We may not have the funds to make additional investments in our portfolio companies which could impair the value of our portfolio.

After our initial investment in a portfolio company, we may be called upon from time to time to provide additional funds to such company or have the opportunity to increase our investment through the exercise of a warrant to purchase common stock. There is no assurance that we will make, or will have sufficient funds to make, follow-on investments. Any decisions not to make a follow-on investment or any inability on our part to make such an investment may have a negative impact on a portfolio company in need of such an investment, may result in a missed opportunity for us to increase our participation in a successful operation or may reduce the expected yield on the investment. Even if we have sufficient capital to make a desired follow-on investment, we may elect not to make a follow-on investment because we may not want to increase our level of risk, because we prefer other opportunities or because we are inhibited by compliance with BDC requirements, SBA regulations or the desire to maintain our RIC tax treatment. Our ability to make follow-on investments may also be limited by our investment advisor’s allocation policy.

Portfolio companies may incur debt that ranks equally with, or senior to, our investments in such companies.

We will invest primarily in second lien and subordinated debt as well as equity issued by lower middle-market companies. The portfolio companies generally have, or may be permitted to incur, other debt that ranks equally with, or senior to, the debt in which we invest. By their terms, such senior debt instruments may entitle the holders to receive payment of interest or principal on or before the dates on which we are entitled to receive payments with respect to the debt instruments in which we invest. Also, in the event of insolvency, liquidation, dissolution, reorganization or bankruptcy of a portfolio company, holders of debt instruments ranking senior to our investment in that portfolio company would typically be entitled to receive payment in full before we receive any distribution. After repaying such senior creditors, such portfolio company may not have any remaining assets to use for repaying its obligation to us. In the case of debt ranking equally with debt instruments in which we invest, we would have to share on an equal basis any distributions with other creditors holding such debt in the event of an insolvency, liquidation, dissolution, reorganization or bankruptcy of the relevant portfolio company.

There may be circumstances where our debt investments could be subordinated to claims of other creditors or could be subject to lender liability claims.

Even though we may have structured certain of our investments as senior loans, if one of our portfolio companies were to go bankrupt, depending on the facts and circumstances, including the extent to which we actually provided managerial assistance to that portfolio company, a bankruptcy court might recharacterize our debt investment and subordinate all or a portion of our claim to that of other creditors. We may also be subject to lender liability claims for actions taken by us with respect to a borrower’s business or instances where we exercise control over the borrower. It is possible that we could become subject to a lender’s liability claim, including as a result of actions taken in rendering significant managerial assistance.

Second priority liens on collateral securing loans that we make to our portfolio companies may be subject to control by senior creditors with first priority liens. If there is a default, the value of the collateral may not be sufficient to repay in full both the first priority creditors and us.

Certain loans we make to portfolio companies are and will be secured on a second priority basis by the same collateral securing senior secured debt of such companies. The first priority liens on the collateral secure the portfolio company’s obligations under any outstanding senior debt and may secure certain other future debt that may be permitted to be incurred by the company under the agreements governing the loans. The holders of obligations secured by the first priority liens on the collateral will generally control the liquidation of and be entitled to receive proceeds from any realization of the collateral to repay their obligations in full before us. In addition, the value of the collateral in the event of liquidation will depend on market and economic conditions, the availability of buyers and other factors. There can be no assurance that the proceeds, if any, from the sale or sales of all of the collateral would be sufficient to satisfy the loan obligations secured by the second priority liens after payment in full of all obligations secured by the first priority liens on the collateral. If such proceeds are not

-34-

sufficient to repay amounts outstanding under the loan obligations secured by the second priority liens, then we, to the extent not repaid from the proceeds of the sale of the collateral, will only have an unsecured claim against the company’s remaining assets, if any.

The rights we may have with respect to the collateral securing the loans we make to portfolio companies with senior debt outstanding may also be limited pursuant to the terms of one or more intercreditor agreements entered into with the holders of senior debt. Under an intercreditor agreement, at any time that obligations having the benefit of the first priority liens are outstanding, any of the following actions that may be taken in respect to the collateral will be at the direction of the holders of the obligations secured by the first priority liens:

We may not have the ability to control or direct such actions, even if our rights are adversely affected.

We may hold the debt securities of leveraged companies that may, due to the significant volatility of such companies, enter into bankruptcy proceedings.

Leveraged companies may experience bankruptcy or similar financial distress. The bankruptcy process has a number of significant inherent risks. Many events in a bankruptcy proceeding are the product of contested matters and adversary proceedings and are beyond the control of the creditors. A bankruptcy filing by an issuer may adversely and permanently affect the issuer. If the proceeding is converted to a liquidation, the value of the issuer may not equal the liquidation value that was believed to exist at the time of the investment. The duration of a bankruptcy proceeding is also difficult to predict, and a creditor’s return on investment can be adversely affected by delays until the plan of reorganization or liquidation ultimately becomes effective. The administrative costs in connection with a bankruptcy proceeding are frequently high and would be paid out of the debtor’s estate prior to any return to creditors. Because the standards for classification of claims under bankruptcy law are vague, our influence with respect to the class of securities or other obligations we own may be lost by increases in the number and amount of claims in the same class or by different classification and treatment. In the early stages of the bankruptcy process, it is often difficult to estimate the extent of, or even to identify, any contingent claims that might be made. In addition, certain claims that have priority by law (for example, claims for taxes) may be substantial.

Any unrealized depreciation we experience on our investment portfolio may be an indication of future realized losses, which could reduce our income available for distribution.

As a BDC, we are required to carry our investments at fair value as determined in good faith by our board of directors. Decreases in the fair values of our investments will be recorded as unrealized depreciation. Any unrealized depreciation in our investment portfolio could be an indication of a portfolio company’s inability to meet its repayment obligations to us with respect to the affected investments. This could result in realized losses in the future and ultimately in reductions of our income available for distribution in future periods.

Defaults by our portfolio companies will harm our operating results.

A portfolio company’s failure to satisfy financial or operating covenants imposed by us or other lenders could lead to defaults and, potentially, termination of its loans and foreclosure on its assets. This could trigger cross-defaults under other agreements and jeopardize the portfolio company’s ability to meet its obligations under the debt or equity securities that we hold. We may incur expenses to the extent necessary to seek recovery upon default or to negotiate new terms, which may include the waiver of certain financial covenants, reduced interest and/or loss of principal, with a defaulting portfolio company.

-35-

To the extent OID and PIK-interest constitute a portion of our income, we will be exposed to typical risks associated with such income being required to be included in taxable and accounting income prior to receipt of cash representing such income.

Our investments may include original-issue-discount instruments and contractual PIK-interest arrangements. To the extent OID or PIK-interest constitutes a portion of our income, we are exposed to typical risks associated with such income being required to be included in taxable and accounting income prior to receipt of cash, including the following:

We do not expect to control many of our portfolio companies.

We do not expect to control many of our portfolio companies, even though we may have board representation or board observation rights, and the debt agreements may contain certain restrictive covenants. As a result, we are subject to the risk that a portfolio company in which we invest may make business decisions with which we disagree and the management of such company, as representatives of the holders of the company’s common equity, may take risks or otherwise act in ways that do not serve our interests as debt investors. Due to the lack of liquidity for our investments in private companies in the lower middle-market, we may not be able to dispose of our interests in our portfolio companies as readily as we would like or at an appropriate valuation. As a result, a portfolio company may make decisions that could decrease the value of our portfolio holdings.

We are a non-diversified investment company within the meaning of the 1940 Act; therefore we are not limited with respect to the proportion of our assets that may be invested in securities of a single issuer.

We are classified as a non-diversified investment company within the meaning of the 1940 Act, which means that we are not limited by the 1940 Act with respect to the proportion of our assets that we may invest in securities of a single issuer. To the extent that we assume large positions in the securities of a small number of issuers, our net asset value may fluctuate to a greater extent than that of a diversified investment company as a result of changes in the financial condition or the market’s assessment of the issuer and the aggregate returns we realize may be significantly adversely affected if a small number of investments perform poorly or if we need to

-36-

write down the value of any one investment. Additionally, while we are not targeting any specific industries, our investments may be concentrated in relatively few industries. As a result, a downturn in any particular industry in which we are invested could also significantly impact the aggregate returns we realize. We may also be more susceptible to any single economic or regulatory occurrence than a diversified investment company. Beyond the asset diversification requirements applicable to RICs, we do not have fixed guidelines for diversification, and our investments could be concentrated in relatively few portfolio companies.

Prepayments of our debt investments by our portfolio companies could adversely impact our results of operations and reduce our return on equity.

We are subject to the risk that the investments we make in our portfolio companies may be repaid prior to maturity. When this occurs, we will generally reinvest these proceeds in temporary investments (cash equivalents), pending future investments in new portfolio companies. These temporary investments will typically have substantially lower yields than the debt being repaid, and we could experience significant delays in reinvesting these amounts. In addition, any future investment of such amounts in a new portfolio company may also be at lower yields than the investment that was repaid. As a result, our results of operations could be materially adversely affected if one or more of our portfolio companies elect to prepay amounts owed to us. Additionally, prepayments could negatively impact our return on equity, which could result in a decline in the market price of our common stock.

We may not realize gains from our equity investments.

Certain investments that we have made in the past and may make in the future include warrants or other equity or equity-related securities. Typically we make non-control, equity investments in portfolio companies. Our goal is to realize gains upon our disposition of such equity interests. However, the equity interests we receive may not appreciate in value and, in fact, may decline in value. We also may be unable to realize any value if a portfolio company does not have a liquidity event, such as a sale of the business, recapitalization or public offering, which would allow us to sell the underlying equity interests. We often seek puts or similar rights to give us the right to sell our equity securities back to the portfolio company issuer. We may be unable to exercise these put rights for the consideration provided in our investment documents if the issuer is in financial distress. Accordingly, we may not be able to realize gains from our equity interests, and any gains that we do realize on the disposition of any equity interests may not be sufficient to offset any other losses we experience.

If our primary investments are deemed not to be qualifying assets, we could be precluded from investing in our desired manner or deemed to be in violation of the 1940 Act.

In order to maintain our status as a BDC, we may not acquire any assets other than “qualifying assets” unless, at the time of and after giving effect to such acquisition, at least 70.0% of our total assets are qualifying assets. We believe that most of the investments that we may acquire in the future will constitute qualifying assets. However, we may be precluded from investing in what we believe are attractive investments if such investments are not qualifying assets for purposes of the 1940 Act. If we do not invest a sufficient portion of our assets in qualifying assets, we could violate the 1940 Act provisions applicable to BDCs and be precluded from making follow-on investments in existing portfolio companies (which could result in the dilution of our position) or required to dispose of investments at inappropriate times in order to come into compliance with the 1940 Act. If we need to dispose of such investments quickly, it could be difficult to dispose of such investments on favorable terms. We may not be able to find a buyer for such investments and, even if we do find a buyer, we may have to sell the investments at a substantial loss. Any such outcomes would have a material adverse effect on our business, financial condition, results of operations and cash flows. Furthermore, any failure to comply with the requirements imposed on BDCs by the 1940 Act could cause the SEC to bring an enforcement action against us and/or expose us to claims of private litigants. If we do not maintain our status as a BDC, we would be subject to regulation as a registered closed-end investment company under the 1940 Act. As a registered closed-end investment company, we would be subject to substantially more regulatory restrictions under the 1940 Act, which would significantly decrease our operating flexibility.

-37-

The disposition of our investments may result in contingent liabilities.

A significant portion of our investments involve private securities and we expect that a significant portion of our investments will continue to involve private securities. In connection with the disposition of an investment in private securities, we may be required to make representations about the business and financial affairs of the portfolio company typical of those made in connection with the sale of a business. Additionally, customary terms of such sales agreements generally provide adjustments to the initial purchase price determined on the closing date if the portfolio company’s net working capital varies from preliminary amounts utilized in determining the initial purchase price; such adjustments could subsequently result in upward or downward revisions to the initial purchase price and impact our amount of realized gain or loss on sale. We may also be required to indemnify the purchasers of such investment to the extent that any such representations turn out to be inaccurate or with respect to potential liabilities. These arrangements may result in contingent liabilities that ultimately result in funding obligations that we must satisfy through its return of distributions previously made to it.

We may be unable to invest a significant portion of any net proceeds from an offering or from exiting an investment or other capital on acceptable terms, which could harm our financial condition and operating results.

We may be unable to invest the net proceeds of any offering or from exiting an investment or other sources of capital on acceptable terms within the time period that we anticipate or at all. Delays in investing such capital may cause our performance to be worse than that of fully invested BDCs or other lenders or investors pursuing comparable investment strategies.

Depending on market conditions and the amount of the capital involved, it may take us a substantial period of time to invest substantially all the capital in securities meeting our investment objective. During this period, we will invest such capital primarily in short-term securities consistent with our BDC election and our election to be taxed as a RIC, which may produce returns that are significantly lower than the returns which we expect to achieve when our portfolio is fully invested in longer-term investments in pursuit of our investment objective. Any distributions that we pay during such period may be substantially lower than the distributions that we may be able to pay when our portfolio is fully invested. In addition, until such time as the net proceeds of any offering or from exiting an investment or other sources capital are invested in new investments meeting our investment objective, the market price for our common stock may decline.

Our investment advisor’s liability is limited under the Investment Advisory Agreement, and we have agreed to indemnify our investment advisor against certain liabilities, which may lead our investment advisor to act in a riskier manner on our behalf than it would when acting for its own account.

Under the Investment Advisory Agreement, our investment advisor does not assume any responsibility to us other than to render the services called for under that agreement, and it is not responsible for any action of our board of directors in following or declining to follow our investment advisor’s advice or recommendations. Under the terms of the Investment Advisory Agreement, our investment advisor and its officers, directors, members, managers, partners, stockholders and employees are not liable to us, any subsidiary of ours, our directors, our stockholders or any subsidiary’s stockholders or partners for acts or omissions performed in accordance with and pursuant to the Investment Advisory Agreement, except those resulting from acts constituting gross negligence, willful misconduct, bad faith or reckless disregard of our investment advisor’s duties under the Investment Advisory Agreement. In addition, we have agreed to indemnify our investment advisor and its officers, directors, members, managers, partners, stockholders and employees from and against any claims or liabilities, including reasonable legal fees and other expenses reasonably incurred, arising out of or in connection with our business and operations or any action taken or omitted on our behalf pursuant to authority granted by the Investment Advisory Agreement, except where attributable to gross negligence, willful misconduct, bad faith or reckless disregard of such person’s duties under the Investment Advisory Agreement. These protections may lead our investment advisor to act in a riskier manner when acting on our behalf than it would when acting for its own account.

Risks Relating to an Offering of Our Securities

Shares of closed-end investment companies, including business development companies, frequently trade at a discount to their net asset value.

Shares of closed-end investment companies, including BDCs, frequently trade at a discount from net asset value. This characteristic of closed-end investment companies and BDCs is separate and distinct from the risk that our net asset value per share may decline. We cannot predict whether our common stock will trade at, above or below net asset value. In addition, if our common stock trades below net asset value, we will generally not be able to issue additional common stock at the market price without first obtaining the approval of our stockholders and our Independent Directors. On June 7, 2018 our stockholders voted to allow us to sell or otherwise issue common stock at a price below net asset value per share for a period of one year ending on the earlier of June 7, 2019 or the date of our 2019 Annual Meeting of Stockholders. We expect to present to our stockholders a similar proposal at our 2019 Annual Meeting of Stockholders. Selling or otherwise issuing shares of FIC’s common stock below its then current net asset value per share would result in a dilution of FIC’s existing common stockholders. The maximum number of shares issuable below net asset value pursuant to the authority granted by our stockholders that could result in such dilution is limited to 25.0% of FIC’s then outstanding common stock immediately prior to each such sale. We do not intend to sell or otherwise issue shares of our common stock below net asset value unless our board of directors determines that it would be in our stockholders’ best interests to do so. The level of net asset value dilution that could result from such an offering is not limited.

Market conditions may increase the risks associated with our business and an investment in us.

The current worldwide financial market situation may contribute to increased market volatility, may have long-term effects on the U.S. and worldwide financial markets and may cause economic uncertainties or deterioration in the U.S. and worldwide. These conditions raised the level of many of the risks described herein and, if repeated or continued, could have an adverse effect on our portfolio companies and on their results of operations, financial conditions, access to credit and capital. The stress in the credit market and upon banks has led other creditors to tighten credit and the terms of credit. In certain cases, senior lenders to our portfolio companies can block payments by our portfolio companies in respect of our loans to such portfolio companies. In turn, these could have adverse effects on our business, financial condition, results of operations, distributions to our stockholders, access to capital, valuation of our assets and our stock price. Notwithstanding any recent gains across either the equity or debt markets, these conditions may continue for a prolonged period of time or worsen in the future.

If, in the future, we sell common stock at a discount to our net asset value per share, stockholders who do not participate in such sale will experience immediate dilution in an amount that may be material.

On June 7, 2018, our stockholders approved our ability to sell or otherwise issue shares of our common stock at a discount from net asset value per share, as long as the cumulative number of shares sold pursuant to such authority does not exceed 25.0% of our then outstanding common stock immediately prior to each such sale, for a period of one year ending on the earlier of June 7, 2019 or the date of our 2019 Annual Meeting of Stockholders. Our stockholders will be asked to vote on a similar proposal at our 2019 Annual Meeting of Stockholders. If we sell or otherwise issue shares of our common stock at a discount to net asset value, it will pose a risk of dilution to our stockholders. In particular, stockholders who do not purchase additional shares at or below the discounted price in proportion to their current ownership will experience an immediate decrease in net asset value per share (as well as in the aggregate net asset value of their shares if they do not participate at all). These stockholders will also experience a disproportionately greater decrease in their participation in our earnings and assets and their voting power than the increase we experience in our assets, potential earning power and voting interests from such issuances or sale. In addition, such issuances or sales may adversely affect the price at which our common stock trades. For additional information and hypothetical examples of these risks, see “Sales of Common Stock Below Net Asset Value,” and for actual dilution illustrations specific to an offering, see the prospectus supplement pursuant to which such sale is made.

-39-

Our net asset value may have changed significantly since our last valuation.

Our board of directors determines the fair value of our portfolio investments on a quarterly basis based on input from our investment advisor, our audit committee and, as to certain of our investments, a third party independent valuation firm. While the board of directors will review our net asset value per share in connection with any offering, it will not always have the benefit of input from the independent valuation firm when it does so. The fair value of various individual investments in our portfolio and/or the aggregate fair value of our investments may change significantly over time. If the fair value of our investment portfolio at December 31, 2018 is less than the fair value was at the time of an offering during 2018, then we may record an unrealized loss on our investment portfolio and may report a lower net asset value per share than was reflected in the Selected Consolidated Financial Data and the financial statements included in the prospectus supplement of that offering. If the fair value of our investment portfolio at December 31, 2018 is greater than the fair value at the time of an offering during 2018, we may record an unrealized gain on our investment portfolio and may report a greater net asset value per share than so reflected in the prospectus supplement of that offering. Upon publication of this information in connection with our announcement of operating results for our fiscal year ended December 31, 2018, the market price of our common stock may fluctuate materially, and may be substantially less than the price per share you pay for our common stock in an offering.

The market price of our securities may fluctuate significantly.

The market price and liquidity of the market for shares of our common stock may be significantly affected by numerous factors, some of which are beyond our control and may not be directly related to our operating performance. These factors include:

Investing in our securities may involve an above average degree of risk.

The investments we make in accordance with our investment objective may result in a higher amount of risk than alternative investment options and a higher risk of volatility or loss of principal. Our investments in portfolio companies may be highly speculative; therefore, an investment in our securities may not be suitable for someone with lower risk tolerance.

-40-

Sales of substantial amounts of our common stock may have an adverse effect on the market price of our common stock.

As of April 24, 2019, we had 24,463,119 shares of common stock outstanding. Sales of substantial amounts of our common stock, or the availability of shares for sale, could adversely affect the prevailing market price of our common stock. If this occurs and continues, it could impair our ability to raise additional capital through the sale of equity securities should we desire to do so.

If we issue preferred stock and/or debt securities, the net asset value and market value of our common stock may become more volatile.

We cannot assure you that the issuance of preferred stock and/or debt securities would result in a higher yield or return to the holders of our common stock. The issuance of preferred stock and/or debt securities would likely cause the net asset value and market value of our common stock to become more volatile. If the distribution rate on the preferred stock, or the interest rate on the debt securities, were to approach the net rate of return on our investment portfolio, the benefit of leverage to the holders of our common stock would be reduced. If the distribution rate on the preferred stock, or the interest rate on the debt securities, were to exceed the net rate of return on our portfolio, the use of leverage would result in a lower rate of return to the holders of common stock than if we had not issued the preferred stock and/or debt securities. Any decline in the net asset value of our investment would be borne entirely by the holders of our common stock. Therefore, if the market value of our portfolio were to decline, the leverage would result in a greater decrease in net asset value to the holders of our common stock than if we were not leveraged through the issuance of preferred stock and/or debt securities. This decline in net asset value would also tend to cause a greater decline in the market price for our common stock.

There is also a risk that, in the event of a sharp decline in the value of our net assets, we would be in danger of failing to maintain required asset coverage ratios which may be required by the preferred stock and/or debt securities or of a downgrade in the ratings of the preferred stock and/or debt securities or our current investment income might not be sufficient to meet the distribution requirements on the preferred stock or the interest payments on the debt securities. In order to counteract such an event, we might need to liquidate investments in order to fund redemption of some or all of the preferred stock and/or debt securities. In addition, we would pay (and the holders of our common stock would bear) all costs and expenses relating to the issuance and ongoing maintenance of the preferred stock and/or debt securities. Holders of preferred stock and/or debt securities may have different interests than holders of common stock and may at times have disproportionate influence over our affairs.

If we issue auction rate preferred stock and you purchase such auction rate preferred stock, you may not be able to sell your auction rate preferred stock at an auction if the auction fails.

If we issue auction rate preferred stock and you purchase such auction rate preferred stock, you may not be able to sell your auction rate preferred stock at an auction if the auction fails, i.e., if more shares of auction rate preferred stock are offered for sale than there are buyers for those shares. Also, if you place an order (a hold order) at an auction to retain auction rate preferred stock only at a specified rate that exceeds the rate set at the auction, you will not retain your auction rate preferred stock. Additionally, if you place a hold order without specifying a rate below which you would not wish to continue to hold your shares and the auction sets a below-market rate, you will receive a lower rate of return on your shares than any market rate of those securities. Finally, the distribution period of these securities may be changed, subject to certain conditions and with notice to the holders of the auction rate preferred stock, which could also affect the liquidity of your investment.

If you try to sell your auction rate preferred stock between auctions, you may not receive full value on your investment.

If you try to sell your auction rate preferred stock between auctions, you may not be able to sell them for their liquidation preference per share or such amount per share plus accumulated distributions. If we have designated a special distribution period of more than seven days, changes in interest rates could affect the price

-41-

you would receive if you sold your shares in the secondary market. Broker-dealers that maintain a secondary trading market for the auction rate preferred stock are not required to maintain this market, and we will not be required to redeem auction rate preferred stock if either an auction or an attempted secondary market sale fails because of a lack of buyers. The auction rate preferred stock will likely not be registered on a stock exchange. If you sell your auction rate preferred stock to a broker-dealer between auctions, you may receive less than the price you paid for them, especially when market interest rates have risen since the last auction or during a special distribution period. Due to recent market disruption most auction-rate preferred stock have been unable to hold successful auctions and holders of such shares have suffered reduced liquidity, including the inability to sell such shares in a secondary market.

The trading market or market value of our debt securities or any convertible debt securities, if issued to the public, may be volatile.

Our debt securities or any convertible debt securities, if issued to the public, may or may not have an established trading market. We cannot assure investors that a trading market for our debt securities or any convertible debt securities, if issued to the public, would develop or be maintained if developed. In addition to our creditworthiness, many factors may materially adversely affect the trading market for, and market value of, our publicly issued debt securities or any convertible debt securities. These factors include, but are not limited to, the following:

There also may be a limited number of buyers for our debt securities. This too may materially adversely affect the market value of the debt securities or the trading market for the debt securities. Our debt securities may include convertible features that cause them to more closely bear risks associated with an investment in our common stock.

Our credit ratings, if any, may not reflect all risks of an investment in our debt securities or any convertible debt securities.

Our credit ratings, if any, will be an assessment by third parties of our ability to pay our obligations. Consequently, real or anticipated changes in our credit ratings will generally affect the market value of any publicly issued debt securities. Our credit ratings, however, may not reflect the potential impact of risks related to market conditions generally or other factors discussed herein about the market value of, or trading market for, any publicly issued debt securities.

Terms relating to redemption may materially adversely affect the return on any debt securities.

If we issue any debt securities or any convertible debt securities that are redeemable at our option, we may choose to redeem the debt securities at times when prevailing interest rates are lower than the interest rate paid on the debt securities. In addition, if the debt securities are subject to mandatory redemption, we may be required to redeem the debt securities at times when prevailing interest rates are lower than the interest rate paid on the debt securities. In this circumstance, a holder of our debt securities may not be able to reinvest the redemption proceeds in a comparable security at an effective interest rate as high as the debt securities being redeemed.

The issuance of subscription rights, warrants or convertible debt that are exchangeable for our common stock, will cause your interest in us to be diluted as a result of any such rights, warrants or convertible debt offering.

Stockholders who do not fully exercise rights, warrants or convertible debt issued to them in any offering of subscription rights, warrants or convertible debt to purchase our common stock should expect that they will, at the completion of the offering, own a smaller proportional interest in us than would otherwise be the case if they fully exercised their rights, warrants or convertible debt. We cannot state precisely the amount of any such dilution in share ownership because we do not know what proportion of the common stock would be purchased as a result of any such offering.

In addition, if the subscription price, warrant price or convertible debt price is less than our net asset value per share of common stock at the time of such offering, then our stockholders would experience an immediate dilution of the aggregate net asset value of their shares as a result of the offering. The amount of any such decrease in net asset value is not predictable because it is not known at this time what the subscription price, warrant price, convertible debt price or net asset value per share will be on the expiration date of such offering or what proportion of our common stock will be purchased as a result of any such offering. The risk of dilution is greater if there are multiple rights offerings. However, our board of directors will make a good faith determination that any offering of subscription rights, warrants or convertible debt would result in a net benefit to existing stockholders.

Future offerings of debt securities, which would be senior to our common stock upon liquidation, or equity securities, which could dilute our existing stockholders and may be senior to our common stock for the purposes of distributions, may harm the value of our common stock.

In the future, we may attempt to increase our capital resources by making additional offerings of debt or equity securities, including commercial paper, medium-term notes, senior or subordinated notes and classes of preferred stock or common stock, subject to the restrictions of the 1940 Act. Upon a liquidation of our company, holders of our debt securities and shares of preferred stock and lenders with respect to other borrowings would receive a distribution of our available assets prior to the holders of our common stock. Additional equity offerings by us may dilute the holdings of our existing stockholders or reduce the value of our common stock, or both. Any preferred stock we may issue would have a preference on distributions that could limit our ability to make distributions to the holders of our common stock. Because our decision to issue securities in any future offering will depend on market conditions and other factors beyond our control, we cannot predict or estimate the amount, timing or nature of our future offerings. Thus, our stockholders bear the risk of our future offerings reducing the market price of our common stock and diluting their stock holdings in us. In addition, proceeds from a sale of common stock will likely be used to increase our total assets or to pay down our borrowings, among other uses. This would increase our asset coverage ratio and permit us to incur additional leverage under rules pertaining to BDCs by increasing our borrowings or issuing senior securities such as preferred stock or additional debt securities.

Provisions of the Maryland General Corporation Law and our charter and bylaws could deter takeover attempts and have an adverse effect on the price of our common stock.

The Maryland General Corporation Law contains provisions that may discourage, delay or make more difficult a change in control of us or the removal of our directors. In addition, our board of directors may, without stockholder action, authorize the issuance of shares of stock in one or more classes or series, including preferred stock. Our charter and bylaws contain provisions that limit liability and provide for indemnification of our directors and officers. These provisions and others also may have the effect of deterring hostile takeovers or delaying changes in control or management. We are generally prohibited from engaging in mergers and other business combinations with stockholders that beneficially own 10.0% or more of the voting power of our outstanding voting stock, or with their affiliates, for five years after the most recent date on which such stockholders became the beneficial owners of 10.0% or more of the voting power of our outstanding voting stock

and thereafter unless our directors and stockholders approve the business combination in the prescribed manner. See “Description of Our Capital Stock—Business Combinations.” Maryland law may discourage third parties from trying to acquire control of us and increase the difficulty of consummating such an offer.

We have also adopted measures that may make it difficult for a third party to obtain control of us, including provisions of our charter authorizing our board of directors to classify or reclassify shares of our stock in one or more classes or series and to cause the issuance of additional shares of our stock, including preferred stock. In addition, we have adopted a classified board of directors. A classified board may render a change in control of us or removal of our incumbent management more difficult. These provisions, as well as other provisions of our charter and bylaws, may delay, defer or prevent a transaction or a change in control that might otherwise be in the best interests of our stockholders.

Our business and operation could be negatively affected if we become subject to any securities litigation or shareholder activism, which could cause us to incur significant expense, hinder execution of investment strategy and impact our stock price.

In the past, following periods of volatility in the market price of a company’s securities, securities class action litigation has often been brought against that company. Shareholder activism, which could take many forms or arise in a variety of situations, has been increasing in the BDC space recently. While we are currently not subject to any securities litigation or shareholder activism, due to the potential volatility of our stock price and for a variety of other reasons, we may in the future become the target of securities litigation or shareholder activism. Securities litigation and shareholder activism, including potential proxy contests, could result in substantial costs and divert management’s and our board of directors’ attention and resources from our business. Additionally, such securities litigation and shareholder activism could give rise to perceived uncertainties as to our future, adversely affect our relationships with service providers and make it more difficult to attract and retain qualified personnel. Also, we may be required to incur significant legal fees and other expenses related to any securities litigation and activist shareholder matters. Further, our stock price could be subject to significant fluctuation or otherwise be adversely affected by the events, risks and uncertainties of any securities litigation and shareholder activism.

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus contains forward-looking statements that involve substantial risks and uncertainties. These forward-looking statements are not historical facts, but rather are based on current expectations, estimates and projections about us, our current and prospective portfolio investments, our industry, our beliefs, and our assumptions. Words such as “anticipates,” “expects,” “intends,” “plans,” “will,” “may,” “continue,” “believes,” “seeks,” “estimates,” “would,” “should,” “targets,” “projects” and variations of these words and similar expressions are intended to identify forward-looking statements. The forward-looking statements contained in this report involve risks and uncertainties, including statements as to:

These statements are not guarantees of future performance and are subject to risks, uncertainties and other factors, some of which are beyond our control and difficult to predict and could cause actual results to differ materially from those expressed or forecasted in the forward-looking statements, including without limitation:

-45-

Although we believe that the assumptions on which these forward-looking statements are based are reasonable, any of those assumptions could prove to be inaccurate, and as a result, the forward-looking statements based on those assumptions also could be inaccurate. Important assumptions include our ability to originate new loans and investments, certain margins and levels of profitability and the availability of additional capital. In light of these and other uncertainties, the inclusion of a projection or forward-looking statement in this prospectus should not be regarded as a representation by us that our plans and objectives will be achieved. These risks and uncertainties include those described or identified in “Risk Factors” and elsewhere in this prospectus. You should not place undue reliance on these forward-looking statements, which apply only as of the date of this prospectus. The forward-looking statements and projections contained in this prospectus are excluded from the safe harbor protection provided by Section 27A of the Securities Act of 1933, as amended, or the Securities Act.

USE OF PROCEEDS

Unless otherwise specified in any prospectus supplement accompanying this prospectus, we intend to use the net proceeds from the sale of our securities to invest in lower middle-market companies in accordance with our investment objective and strategies, to repay the outstanding indebtedness under our Credit Facility, if any, and for working capital and general corporate purposes. We will also pay operating expenses, including management, incentive and administrative fees, and may pay other expenses, from the net proceeds of any offering. We plan to raise new equity when we have attractive investment opportunities available. Pending such use, we will invest the net proceeds of any offering primarily in short-term securities consistent with our BDC election and our election to be taxed as a RIC. See “Regulation—Temporary Investments” for additional information about temporary investments we may make while waiting to make longer-term investments in pursuit of our investment objective.

Pending such use, we will invest the net proceeds of this offering primarily in cash, cash equivalents, U.S. Government securities and other high-quality debt instruments that mature in one year or less, or “temporary investments,” as appropriate. These securities may have lower yields than our other investments and accordingly result in lower distributions, if any, by us during such period. See “Regulation—Temporary Investments.” Our ability to achieve our investment objective may be limited to the extent that the net proceeds from the offering, pending full investment, are held in interest bearing deposits or other short-term instruments that produce income at a rate less than our cost of capital.

PRICE RANGE OF COMMON STOCK AND DISTRIBUTIONS

Our common stock began trading on June 21, 2011 on the NASDAQ Global Market under the symbol “FDUS.” Effective January 3, 2012, our common stock was included in the Nasdaq Global Select Market. The following table lists the high and low closing sale price for our common stock, and the closing sale price as a percentage of net asset value, or NAV, and the cash distributions per share that we have declared on our common stock for each fiscal quarter during the last two most recently completed fiscal years and through April 24, 2019.

Shares of BDCs may trade at a market price that is less than the net asset value of those shares. The possibilities that our shares of common stock will trade at a discount from net asset value or at premiums that are unsustainable over the long term are separate and distinct from the risk that our net asset value will decrease. It is not possible to predict whether any common stock offered pursuant to this prospectus supplement will trade at, above, or below net asset value.

We intend to continue to pay quarterly distributions to our stockholders. Our distributions may include returns of paid-in capital, as well as declared dividends from earnings and profits. Our quarterly distributions, if any, are determined by our board of directors. We have elected to be taxed as a RIC under Subchapter M of the Code. As long as we qualify for tax treatment as a RIC, we will not be taxed on our investment company taxable income or net capital gain, to the extent that such income or gain is distributed, or deemed to be distributed, to stockholders on a timely basis.

There were no deemed distributions during the years 2018, 2017 or 2016.

-48-

We may not be able to achieve operating results that will allow us to make distributions at a specific level or to increase the amount of these distributions from time to time. If we do not distribute a certain percentage of our income annually, we will suffer adverse tax consequences, including possible loss of our tax treatment as a RIC. We cannot assure stockholders that they will receive any distributions at a particular level.

We have adopted a dividend reinvestment plan that provides for reinvestment of our distributions on behalf of our stockholders, unless a stockholder elects to receive cash. As a result, if our board of directors authorizes, and we declare, a cash distribution, then our stockholders who have not “opted out” of our dividend reinvestment plan will have their cash distribution automatically reinvested in additional shares of our common stock, rather than receiving the cash distribution. Under the terms of our dividend reinvestment plan, dividends will primarily be paid in newly issued shares of common stock. However, we reserve the right to purchase shares in the open market in connection with the implementation of the plan. This feature of the plan means that, under certain circumstances, we may issue shares of our common stock at a price below net asset value per share, which could cause our stockholders to experience dilution.

To maintain our tax treatment as a RIC, we must, among other things, distribute at least 90.0% of our net ordinary income and our net short-term capital gains in excess of our net long-term capital losses, if any. In order to avoid certain excise taxes imposed on RICs, we currently intend to distribute during each calendar year an amount at least equal to the sum of (1) 98.0% of our net ordinary income for the calendar year, (2) 98.2% of our capital gain net income for the calendar year and (3) any net ordinary income and capital gain net income for the preceding calendar year that were not distributed during such year and on which we paid no U.S. federal income tax. We may retain for investment some or all of our net capital gain (i.e., net long-term capital gains in excess of net short-term capital losses) and treat such amounts as deemed distributions to our stockholders. If we do this, you will be treated as if you received an actual distribution of the capital gain we retain and then reinvested the net after-tax proceeds in our common stock. You also may be eligible to claim a tax credit (or, in certain circumstances, a tax refund) equal to your allocable share of the tax we paid on the capital gain deemed distributed to you. Please refer to “Material U.S. Federal Income Tax Considerations” for further information regarding the consequences of our retention of net capital gain. We can offer no assurance that we will achieve results that will permit the payment of any cash distributions and, if we issue senior securities, we will be prohibited from making distributions if doing so causes us to fail to maintain the asset coverage ratios stipulated by the 1940 Act or if distributions are limited by the terms of any of our borrowings. See “Regulation” and “Material U.S. Federal Income Tax Considerations.”

We may make distributions that are payable in cash or shares of our common 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. This published guidance applies even if the aggregate amount of cash available to be distributed to all stockholders is no more than 20% of the aggregate declared distribution. Under the published guidance, 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 decide to make any distributions that are payable in part in shares of our stock, U.S. stockholders receiving such distributions generally 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

-49-

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.

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 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. Our board of directors presently intends to declare and pay quarterly dividends. Our ability to pay dividends could be affected by future business performance, liquidity, capital needs, alternative investment opportunities and loan covenants.
