PROSPECTUS SUPPLEMENT
(to Prospectus dated July 11, 2019)
Horizon Technology Finance Corporation
Up to $50,000,000

Common Stock
We have entered into an at market issuance sales agreement, dated August 2, 2019, or the Equity Distribution Agreement, with Goldman Sachs & Co. LLC, or Goldman Sachs, and B. Riley FBR, Inc., or B. Riley FBR, relating to the shares of common stock offered by this prospectus. Our common stock is listed on the Nasdaq Global Select Market, or Nasdaq, under the symbol “HRZN”. The last reported sale price on Nasdaq on August 1, 2019 was $12.10. The net asset value per share of our common stock at June 30, 2019 (the last date prior to the date of this prospectus supplement on which we determined net asset value) was $11.60.
We are a non-diversified, closed-end management investment company that has elected to be regulated as a business development company, or BDC, under the Investment Company Act of 1940, as amended. We are externally managed by Horizon Technology Finance Management LLC, a registered investment adviser under the Investment Advisers Act of 1940, as amended. Our investment objective is to maximize our investment portfolio’s total return by generating current income from the debt investments we make and capital appreciation from the warrants we receive when making such debt investments. Substantially all of our investments consist of secured debt investments to development-stage companies in the technology, life science, healthcare information and services and cleantech industries.
The Equity Distribution Agreement provides that we may offer and sell up to $50 million worth of our common stock from time to time through Goldman Sachs and B. Riley FBR, which we refer to as the “Agents”. Sales of our common stock, if any, under this prospectus supplement and the accompanying prospectus may be made in negotiated transactions or transactions that are deemed to be “at the market,” as defined in Rule 415 under the Securities Act of 1933, as amended, or the Securities Act, including sales made directly on the Nasdaq or similar securities exchange or sales made to or through a market maker other than on an exchange, at prices related to the prevailing market prices or at negotiated prices.
The Agents will receive a commission from us of 1.75% of the gross sales price of any shares of our common stock sold through the Agents under the Equity Distribution Agreement. The Agents are not required to sell any specific number or dollar amount of common stock, but will use their commercially reasonable efforts consistent with their sales and trading practices to sell the shares of our common stock offered by this prospectus supplement and the accompanying prospectus. See “Plan of Distribution” in this prospectus supplement. The sales price per share of our common stock offered by this prospectus supplement and the accompanying prospectus, less the Agents’ commission, will not be less than the net asset value per share of our common stock at the time of such sale.
Investing in our common stock should be considered highly speculative, and involves a high degree of risk including the risk of a substantial loss of investment and the risk of leverage and dilution. Before purchasing any shares of our common stock, you should read the discussion of the principal risks of investing in our securities, which are summarized in “Risk Factors” in this prospectus supplement, in the accompanying prospectus, in our most recent Annual Report on Form 10-K, in any of our other filings with the Securities and Exchange Commission, and in any free writing prospectus to read about risks that you should consider before investing in our common stock, including the risk of leverage.

TABLE OF CONTENTS
PROSPECTUS SUPPLEMENT SUMMARY
This summary highlights some of the information in this prospectus supplement and the accompanying prospectus. It is not complete and may not contain all of the information that you may want to consider before investing in our common stock. To understand the terms of the common stock we are offering, you should read the entire prospectus supplement and the accompanying prospectus carefully. Together, these documents describe the specific terms of the shares we are offering. You should carefully read the sections titled “Risk Factors,” “Selected Consolidated Financial and Other Data,” “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and “Financial Statements” as well as the documents identified in the section titled “Available Information” in this prospectus supplement.
Horizon Technology Finance Corporation, a Delaware corporation, was formed on March 16, 2010 for the purpose of acquiring, continuing and expanding the business of its wholly owned subsidiary, Compass Horizon Funding Company LLC, a Delaware limited liability company, which we refer to as “Compass Horizon,” raising capital in its initial public offering, or IPO, and operating as an externally managed BDC under the Investment Company Act of 1940, as amended, or the 1940 Act. Except where the context suggests otherwise, the terms “we,” “us,” “our” and “Company” refer to Horizon Technology Finance Corporation and its consolidated subsidiaries. In addition, we refer to Horizon Technology Finance Management LLC, a Delaware limited liability company, as “HTFM,” our “Advisor” or our “Administrator.”
Our Company
We are a specialty finance company that lends to and invests in development-stage companies in the technology, life science, healthcare information and services and cleantech industries, which we refer to collectively as our “Target Industries.” Our investment objective is to maximize our investment portfolio’s total return by generating current income from the debt investments we make and capital appreciation from the warrants we receive when making such debt investments. We are focused on making secured debt investments, which we refer to as “Venture Loans,” to venture capital backed companies in our Target Industries, which we refer to as “Venture Lending.” We also selectively provide Venture Loans to publicly traded companies in our Target Industries. Our debt investments are typically secured by first liens or first liens behind a secured revolving line of credit, or “Senior Term Loans.” Venture Lending is typically characterized by (1) the making of a secured debt investment after a venture capital or equity investment in the portfolio company has been made, which investment provides a source of cash to fund the portfolio company’s debt service obligations under the Venture Loan, (2) the senior priority of the Venture Loan which requires repayment of the Venture Loan prior to the equity investors realizing a return on their capital, (3) the relatively rapid amortization of the Venture Loan and (4) the lender’s receipt of warrants or other success fees with the making of the Venture Loan.
We are an externally managed, closed-end, non-diversified management investment company that has elected to be regulated as a BDC under the 1940 Act. In addition, for U.S. federal income tax purposes, we have elected to be treated as a regulated investment company, or RIC, under Subchapter M of the Internal Revenue Code of 1986, as amended, or the Code. As a BDC, we are required to comply with regulatory requirements, including limitations on our use of debt. We are permitted to, and expect to, finance a portion of our investments through borrowings. On March 23, 2018, the Small Business Credit Availability Act, or SBCAA, amended Section 61(a) of the 1940 Act to add Section 61(a)(2) which enables BDCs to reduce their asset coverage requirements from 200% to 150%. This provision permits a BDC to double the maximum amount of leverage that it is permitted to incur, so long as the BDC meets certain disclosure requirements and obtains certain approvals. As defined in the 1940 Act, asset coverage of 150% means that for every $100 of net assets a BDC holds, it may raise up to $200 from borrowing and issuing senior securities. We received approval from our stockholders to reduce our asset coverage requirement from 200% to 150% on October 30, 2018. The amount of leverage that we may employ will depend on our assessment of market conditions and other factors at the time of any proposed borrowing. As a RIC, we generally do not have to pay corporate-level federal income taxes on our investment company taxable income and our net capital gain that we distribute to our stockholders as long as we meet certain source-of-income, distribution, asset diversification and other requirements.

TABLE OF CONTENTS
THE OFFERING
Common stock offered by us
$50 million of shares
Common stock outstanding prior to this offering
13,544,212 shares
Manner of offering
“At the market” offering that may be made from time to time through Goldman Sachs and B. Riley FBR, as sales agents, using commercially reasonable efforts. See “Plan of Distribution” in this prospectus supplement.
Use of proceeds
We intend to use substantially all of the net proceeds from this offering to make investments in development-stage companies in accordance with our investment objective and strategies described in this prospectus supplement, the accompanying prospectus, and the documents incorporated by reference, and for general corporate purposes. We may also use a portion of the net proceeds to reduce any of our outstanding borrowings. Pending such use, we will invest the net proceeds primarily in high quality, short-term investments, consistent with our business development company election and our election to be taxed as a RIC.
See “Use of Proceeds” in this prospectus supplement for more information.
Distributions
We intend to continue to pay monthly distributions to our stockholders out of assets legally available for distribution. Our distributions, if any, will be determined by our board of directors, or the Board. Our ability to declare distributions depends on our earnings, our overall financial condition (including our liquidity position), maintenance of RIC status and such other factors as our Board may deem relevant from time to time.
To the extent our taxable earnings fall below the total amount of our distributions for any given fiscal year, a portion of those distributions may be deemed to be a return of capital to our common stockholders for U.S. federal income tax purposes.
Thus, the source of a distribution to our stockholders may be the original capital invested by the stockholder rather than our income or gains. Stockholders should read any written disclosure accompanying a distribution payment carefully and should not assume that the source of any distribution is our ordinary income or gains.
Dividend Reinvestment Plan
We have adopted a dividend reinvestment plan, or DRIP, for our stockholders. The DRIP is an “opt out” DRIP. As a result, distributions to our stockholders are automatically reinvested in additional shares of our common stock, unless a stockholder specifically “opts out” of the DRIP so as to receive cash distributions. Stockholders who receive distributions in the form of stock will generally be subject to the same federal, state and local tax consequences as stockholders who elect to receive their distributions in cash. See “Dividend Reinvestment Plan” in accompanying prospectus.

TABLE OF CONTENTS
Taxation
We have elected to be treated as a RIC. Accordingly, we generally will not incur corporate-level income taxes on any investment company taxable income determined without regard to any deductions for dividends paid and net capital gains that we distribute as dividends for U.S. federal income tax purposes to our stockholders. To maintain RIC tax treatment, we must meet specified source-of-income and asset diversification requirements and distribute annually an amount generally equal to at least 90% of our investment company taxable income, determined without regard to any deduction for dividends paid.
Listing
Our common stock is traded on Nasdaq under the symbol “HRZN”.

TABLE OF CONTENTS
FEES AND EXPENSES
The following table is intended to assist you in understanding the costs and expenses that an investor in shares of our common stock will bear directly or indirectly. However, we caution you that some of the percentages indicated in the table below are estimates and may vary. The following table and example should not be considered a representation of our future expenses. Actual expenses may be greater or less than shown. Except where the context suggests otherwise, whenever this prospectus supplement and the accompanying prospectus contain a reference to fees or expenses paid by “you” or “us” or that “we” will pay fees or expenses, stockholders will indirectly bear such fees or expenses as investors in the Company.

(1)
Represents the estimated commissions with respect to the shares sold by us in this offering.
(2)
The offering expenses of this offering borne by us are estimated to be approximately $250,000.
(3)
The expenses associated with the DRIP are included in “Other Expenses” in the table. See “Dividend Reinvestment Plan” in the accompanying prospectus.
(4)
Net Assets Attributable to Common Stock equals estimated average net assets for the current fiscal year and is based on our net assets at June 30, 2019 and includes the net proceeds of the offering estimated to be received by the Company.
(5)
Our base management fee under the Investment Management Agreement is based on our gross assets, less cash and cash equivalents, which includes assets acquired using leverage, including any leverage disclosed in the accompanying prospectus, and is payable monthly in arrears. The management fee referenced in the table above is based on our gross assets, less cash and cash equivalents, of $282 million as of June 30, 2019 and includes net proceeds of the offering, after the net proceeds have been invested in portfolio companies, and $58 million of assets estimated to be acquired in the current fiscal year using leverage. See “Investment Management and Administration Agreements —  Investment Management Agreement” in the accompanying prospectus.
(6)
Our incentive fee payable under the Investment Management Agreement consists of two parts:
The first part, which is payable quarterly in arrears, subject to a Fee Cap and Deferral Mechanism, equals 20% of the excess, if any, of our Pre-Incentive Fee Net Investment Income over a 1.75% quarterly (7% 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 Advisor receives no incentive fee until our net investment income equals the hurdle rate of 1.75% but then receives, as a “catch-up,” 100% 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 2.1875%. The effect of this provision is that, if Pre-Incentive Fee Net Investment Income exceeds 2.1875% in any
S-5

TABLE OF CONTENTS
calendar quarter, our Advisor will receive 20% of our Pre-Incentive Fee Net Investment Income as if a hurdle rate did not apply. The first part of the incentive fee is computed and paid on income that may include interest that is accrued but not yet received in cash.
The second part of the incentive fee equals 20% of our Incentive Fee Capital Gains, if any. Incentive Fee Capital Gains are our realized capital gains on a cumulative basis from inception through the end of each calendar year, computed net of all realized capital losses and unrealized capital depreciation on a cumulative basis, less the aggregate amount of any previously paid capital gain incentive fees. The second part of the incentive fee is payable, in arrears, at the end of each calendar year (or upon termination of the Investment Management Agreement, as of the termination date). For a more detailed discussion of the calculation of this fee, see “Investment Management and Administration Agreements — Investment Management Agreement” in the accompanying prospectus.
The incentive payable to our Advisor represents our estimated annual expense incurred under the first part of the incentive fee payable under the Investment Management Agreement over the next twelve months. As of June 30, 2019, our cumulative realized capital gains and unrealized capital appreciation did not exceed our cumulative realized capital losses and unrealized capital depreciation. Given our strategy of investing primarily in Venture Loans, which are fixed-income assets, we believe it is unlikely that our cumulative realized capital gains and unrealized capital appreciation will exceed our cumulative realized capital losses and unrealized capital depreciation in the next twelve months. Consequently, we do not expect to incur any Incentive Fee Capital Gains during the next twelve months. As we cannot predict the occurrence of any capital gains from the portfolio, we have assumed no Incentive Fee Capital Gains.
(7)
Interest payments on borrowed funds represent our estimated annual interest payments on borrowed funds based on current debt levels as adjusted for projected increases in debt levels over the next twelve months. We may issue additional debt securities pursuant to the registration statement of which this prospectus supplement forms a part. In the event we were to issue additional debt securities, our borrowing costs, and correspondingly our total annual expenses, including, in the case of such preferred stock, our base management fee as a percentage of our net assets attributable to common stock, would increase.
(8)
“Other Expenses” includes our overhead expenses, including payments under the Administration Agreement, based on our allocable portion of overhead and other expenses incurred by the Administrator in performing its obligations under the Administration Agreement. See “Investment Management and Administration Agreements — Administration Agreement” in the accompanying prospectus. “Other expenses” also includes the ongoing administrative expenses to the independent accountants and legal counsel of the Company and compensation of independent directors.
(9)
Our stockholders indirectly bear the expenses of underlying funds or other investment vehicles that would be investment companies under Section 3(a) of the 1940 Act but for the exceptions to that definition provided for in Section 3(c)(1) and 3(c)(7) of the 1940 Act, or Acquired Funds, in which we invest.
Specifically, our stockholders indirectly bear the expenses of our investment in Horizon Secured Loan Fund I, or HSLFI. No management fee is paid by HSLFI. Included in the expenses indirectly borne by our investment is HSLFI are interest expense, professional fees, as well as bank and custody fees. Future fees and expenses for Acquired Funds, including HSLFI, may be substantially higher or lower because certain fees and expenses are based on performance of such Acquired Funds, which may fluctuate over time.
(10)
“Total Annual Expenses” as a percentage of consolidated net assets attributable to common stock are higher than the total annual expenses percentage would be for a company that is not leveraged. We borrow money to leverage our net assets and increase our total assets. The SEC requires that the “Total Annual Expenses” percentage be calculated as a percentage of net assets (defined as total assets less indebtedness and after taking into account any incentive fees payable during the period), rather than the total assets, including assets that have been funded with borrowed monies.

TABLE OF CONTENTS
Example
The following example demonstrates the projected dollar amount of total cumulative expenses that would be incurred over various periods with respect to a hypothetical investment in our common stock. 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. In calculating the following expense amounts, we have assumed that our annual operating expenses remain at the levels set forth in the table above.
1 Year
3 Years
5 Years
10 Years
You would pay the following expenses on a $1,000 investment, assuming a 5% annual return
$ 146.00 $ 394.00 $ 593.00 $ 936.00
The example and the expenses in the tables above should not be considered a representation of our future expenses, and actual expenses may be greater or lesser than those shown.
While the example assumes, as required by the applicable rules of the SEC, a 5% annual return, our performance will vary and may result in a return greater or less than 5%. The incentive fee under the Investment Management Agreement is unlikely to be significant assuming a 5% annual return and is not included in the example. This illustration assumes that we will not realize any capital gains (computed net of all realized capital losses and unrealized capital depreciation) in any of the indicated time periods. 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 distributions to our common stockholders and our expenses would likely be higher. If the 5% annual return were derived entirely from capital gains, you would pay expenses on a $1,000 investment of  $132.00, $363.00, $554.00 and $903.00 over periods of one year, three years, five years and ten years, respectively. See “Investment Management and Administration Agreements —  Investment Management Agreement — Examples of Incentive Fee Calculation” in the accompanying prospectus for additional information regarding the calculation of incentive fees.
In addition, while the example assumes reinvestment of all dividends and other distributions at net asset value, or NAV participants in our DRIP 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. This price may be at, above or below NAV. See “Dividend Reinvestment Plan” in the accompanying prospectus for additional information regarding our DRIP.

TABLE OF CONTENTS
RISK FACTORS
Investing in our securities may be speculative and involves a high degree of risk. You should carefully consider the risk factors incorporated by reference from our most recent Annual Report on Form 10-K and any subsequent Quarterly Reports on Form 10-Q or Current Reports on Form 8-K we file after the date of this prospectus supplement, and all other information contained or incorporated by reference into this prospectus supplement, the accompanying prospectus, and any free writing prospectus, as updated by our subsequent filings under the Exchange Act. Additional risks and uncertainties not presently known to us or not presently deemed material by us may also impair our operations and performance. Each of the risk factors could materially adversely affect our business, financial condition and results of operations. In such case, our NAV and the trading price of our securities could decline, and you may lose all or part of your investment.

TABLE OF CONTENTS
USE OF PROCEEDS
Sales of our common stock, if any, under this prospectus supplement and the accompanying prospectus may be made in negotiated transactions that are deemed to be “at the market” as defined in Rule 415 under the Securities Act, including sales made directly on the Nasdaq or sales made to or through a market maker other than an exchange. There is no guarantee that there will be any sales of our common stock pursuant to this prospectus supplement and the accompanying prospectus. Actual sales, if any, of our common stock under this prospectus supplement and the accompanying prospectus may be less than as set forth in this paragraph. Assuming the sale of  $50 million worth of shares of common stock on the Nasdaq, we estimate that the net proceeds of this offering will be approximately $48.9 million after deducting the estimated sales commission payable to the Sales Agents and our estimated offering expenses.
We expect to use the net proceeds from this offering to fund investments in debt securities in accordance with our investment objective and for other general corporate purposes.
We intend to seek to invest the net proceeds received in this offering as promptly as practicable after receipt of such proceeds consistent with our investment objective. We anticipate that substantially all of the net proceeds from any offering of our securities will be used as described above within three to six months, depending on market conditions. We anticipate that the remainder will be used for working capital and general corporate purposes, including potential payments or distributions to shareholders. Pending such use, we intend to invest a portion of the net proceeds of this offering in short-term investments, such as cash and cash equivalents, which we expect will earn yields substantially lower than the interest income that we anticipate receiving in respect of investments in accordance with our investment objective.

TABLE OF CONTENTS
PLAN OF DISTRIBUTION
We have entered into an at market issuance sales agreement with Goldman Sachs & Co. LLC and B. Riley FBR, Inc. (which we collectively refer to as the “Agents”), under which we may offer and sell from time to time our common stock having an aggregate offering price of up to $50 million. The Agents may act as agent on our behalf or purchase shares of our common stock as principal.
Sales, if any, of common stock under the at market sales agreement may be made in ordinary brokers’ transactions, to or through a market maker, on or through the Nasdaq Global Select Market or any other market venue where the securities may be traded, in the over-the-counter market, in privately negotiated transactions, or through a combination of any such methods of sale. The Agents may also sell our common stock by any other method permitted by law.
The securities may be sold at market prices prevailing at the time of sale, at prices related to such prevailing market prices or at negotiated prices.
We will designate the minimum amount of common stock to be sold through the sales agent, the time period during which sales are requested to be made, any limitation on the number of shares of common stock that may be sold in any one trading day and any minimum price below which sale may not be made. Subject to the terms and conditions of the at market issuance sales agreement, the Agents will use their commercially reasonable efforts consistent with their normal sales and trading practices to sell on our behalf all of the designated shares of common stock. We may instruct the Agents not to sell any common stock if the sales cannot be effected at or above the price designated by us in any such instruction. We or the Agents may suspend the offering of our common stock by notifying the other party.
The Agents will provide to us written confirmation no later than the opening of the trading day immediately following the trading day on which they have made sales under the at market issuance sales agreement. Each confirmation will include the number of shares of common stock sold on such day, the net sales proceeds and the compensation payable by us to the Agents. We will report at least quarterly the number of shares of common stock sold through the sales agent under the at market issuance sales agreement, the net proceeds to us (before expenses) and the compensation paid by us to the Agents in connection with the sales of the shares of common stock.
We will pay the Agents a commission of 1.75% of the gross sales price per share of common stock sold through the Agents under the at market issuance sales agreement. We have also agreed to reimburse the Agents for certain of their expenses.
Settlement of any sales of common stock will occur on second business day following the date on which such sales were made (or such earlier day as is industry practice for regular-way trading). There is no arrangement for funds to be received in an escrow, trust or similar arrangement.

We are a non-diversified closed-end 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”). We are externally managed by Horizon Technology Finance Management LLC, a registered investment adviser under the Investment Advisers Act of 1940, as amended (the “Advisers Act”). Our investment objective is to maximize our investment portfolio’s total return by generating current income from the debt investments we make and capital appreciation from the warrants we receive when making such debt investments. We make secured debt investments to development-stage companies in the technology, life science, healthcare information and services and cleantech industries.
We may offer, from time to time, in one or more offerings or series, together or separately, up to $250,000,000 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.”
We may sell our securities 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. In the event we offer common stock or warrants or rights to acquire such common stock hereunder, the offering price per share of our common stock less any underwriting commissions or discounts will not be less than the net asset value per share of our common stock at the time we make the offering except (1) in connection with the exercise of certain warrants, options or rights whose issuance has been approved by our stockholders at an exercise or conversion price not less than the market value of our common stock at the date of issuance (or, if no such market value exists, the net asset value per share of our common stock as of such date); (2) to the extent such an offer or sale is approved by our stockholders and by our board of directors (our “Board”); or (3) under such other circumstances as may be permitted under the 1940 Act or by the Securities and Exchange Commission (the “SEC”).
Our common stock is listed on The Nasdaq Global Select Market (“Nasdaq”) under the symbol “HRZN”. In addition, our 6.25% Notes due 2022 trade on the New York Stock Exchange under the ticker symbol “HTFA”. On June 19, 2019, the last reported sale price of a share of our common stock on Nasdaq was $11.69. The net asset value per share of our common stock at March 31, 2019 (the last date prior to the date of this prospectus on which we determined net asset value) was $11.55.
Shares of closed-end investment companies, including BDCs, frequently trade at a discount to their net asset value. If our shares trade at a discount to net asset value, it may increase the risk of loss for purchasers in this public offering.

We will provide the specific terms of these offerings and securities in one or more supplements to this prospectus.

Except where the context suggests otherwise, the terms “we,” “us,” “our” and “Company” refer to our predecessor Compass Horizon Funding Company, LLC and its consolidated subsidiary prior to our initial public offering, or IPO, and to Horizon Technology Finance Corporation and its consolidated subsidiaries after the IPO. The terms our “Advisor” and our “Administrator” refer to Horizon Technology Finance Management, LLC, a Delaware limited liability company, and, where the context requires, Horizon Technology Finance, LLC, or “HTF”, our Advisor’s predecessor.
Our company
We are a specialty finance company that lends to and invests in development-stage companies in the technology, life science, healthcare information and services and cleantech industries, which we refer to collectively as our “Target Industries.” Our investment objective is to maximize our investment portfolio’s total return by generating current income from the debt investments we make and capital appreciation from the warrants we receive when making such debt investments. We are focused on making secured debt investments, which we refer to as “Venture Loans,” to venture capital backed companies in our Target Industries, which we refer to as “Venture Lending.” We also selectively provide Venture Loans to publicly traded companies in our Target Industries. Our debt investments are typically secured by first liens or first liens behind a secured revolving line of credit, or “Senior Term Loans.” Venture Lending is typically characterized by (1) the making of a secured debt investment after a venture capital or equity investment in the portfolio company has been made, which investment provides a source of cash to fund the portfolio company’s debt service obligations under the Venture Loan, (2) the senior priority of the Venture Loan which requires repayment of the Venture Loan prior to the equity investors realizing a return on their capital, (3) the relatively rapid amortization of the Venture Loan and (4) the lender’s receipt of warrants or other success fees with the making of the Venture Loan.
We are an externally managed, closed-end, non-diversified management investment company that has elected to be regulated as a BDC under the 1940 Act. In addition, for U.S. federal income tax purposes, we have elected to be treated as a regulated investment company, or RIC, under Subchapter M of the Internal Revenue Code of 1986, as amended, or the Code. As a BDC, we are required to comply with regulatory requirements, including limitations on our use of debt. We are permitted to, and expect to, finance a portion of our investments through borrowings. On March 23, 2018, the Small Business Credit Availability Act, or SBCAA, amended Section 61(a) of the 1940 Act to add Section 61(a)(2) which enables BDCs to reduce their asset coverage requirements from 200% to 150%. This provision permits a BDC to double the maximum amount of leverage that it is permitted to incur, so long as the BDC meets certain disclosure requirements and obtains certain approvals. As defined in the 1940 Act, asset coverage of 150% means that for every $100 of net assets a BDC holds, it may raise up to $200 from borrowing and issuing senior securities. We received approval from our stockholders to reduce our asset coverage requirement from 200% to 150% on October 30, 2018. The amount of leverage that we may employ will depend on our assessment of market conditions and other factors at the time of any proposed borrowing. As a RIC, we generally do not have to pay corporate-level federal income taxes on our investment company taxable income and our net capital gain that we distribute to our stockholders as long as we meet certain source-of-income, distribution, asset diversification and other requirements.
We are externally managed and advised by our Advisor. Our Advisor manages our day-to-day operations and also provides all administrative services necessary for us to operate.

TABLE OF CONTENTS
Our advisor
Our investment activities are managed by our Advisor, and we expect to continue to benefit from our Advisor’s ability to identify attractive investment opportunities, conduct diligence on and value prospective investments, negotiate investments and manage our portfolio of investments. In addition to the experience gained from the years that they have worked together both at our Advisor and prior to the formation of our Advisor, the members of our investment team have broad lending backgrounds, with substantial experience at a variety of commercial finance companies, technology banks and private debt funds, and have developed a broad network of contacts within the venture capital and private equity community. This network of contacts provides a principal source of investment opportunities.
Our Advisor is led by five senior managers including Robert D. Pomeroy, Jr., our Chief Executive Officer, Gerald A. Michaud, our President, Daniel R. Trolio, our Senior Vice President and Chief Financial Officer, John C. Bombara, our Senior Vice President, General Counsel and Chief Compliance Officer, and Daniel S. Devorsetz, our Senior Vice President and Chief Investment Officer.
Our strategy
Our investment objective is to maximize our investment portfolio’s total return by generating current income from the loans we make and capital appreciation from the warrants we receive when making such loans. To further implement our business strategy, we expect our Advisor to continue to employ the following core strategies:

Structured investments in the venture capital and private and public equity markets.   We make loans to development-stage companies within our Target Industries typically in the form of secured loans. The secured debt structure provides a lower risk strategy, as compared to equity or unsecured debt investments, to participate in the emerging technology markets because the debt structures we typically utilize provide collateral against the downside risk of loss, provide return of capital in a much shorter timeframe through current-pay interest and amortization of principal and have a senior position to equity in the borrower’s capital structure in the case of insolvency, wind down or bankruptcy. Unlike venture capital and private equity investments, our investment returns and return of our capital do not require equity investment exits such as mergers and acquisitions or IPOs. Instead, we receive returns on our debt investments primarily through regularly scheduled payments of principal and interest and, if necessary, liquidation of the collateral supporting the debt investment upon a default. Only the potential gains from warrants depend upon equity investment exits.

“Enterprise value” lending.   We and our Advisor take an enterprise value approach to structuring and underwriting loans. Enterprise value includes the implied valuation based upon recent equity capital invested as well as the intrinsic value of the applicable portfolio company’s particular technology, service or customer base. We secure our lien position against the enterprise value of each portfolio company.

Creative products with attractive risk-adjusted pricing.   Each of our existing and prospective portfolio companies has its own unique funding needs for the capital provided from the proceeds of our Venture Loans. These funding needs include funds for additional development “runways”, funds to hire or retain sales staff or funds to invest in research and development in order to reach important technical milestones in advance of raising additional equity. Our loans include current-pay interest, commitment fees, end-of-term payments, or ETPs, pre-payment fees, success fees and non-utilization fees. We believe we have developed pricing tools, structuring techniques and valuation metrics that satisfy our portfolio companies’ financing requirements while mitigating risk and maximizing returns on our investments.

Opportunity for enhanced returns.   To enhance our debt investment portfolio returns, in addition to interest and fees, we frequently obtain warrants to purchase the equity of our portfolio companies as additional consideration for making debt investments. The warrants we obtain generally include a “cashless exercise” provision to allow us to exercise these rights without
2

TABLE OF CONTENTS
requiring us to make any additional cash investment. Obtaining warrants in our portfolio companies has allowed us to participate in the equity appreciation of our portfolio companies, which we expect will enable us to generate higher returns for our investors.

Direct origination.   We originate transactions directly with technology, life science, healthcare information and services and cleantech companies. These transactions are referred to our Advisor from a number of sources, including referrals from, or direct solicitation of, venture capital and private equity firms, portfolio company management teams, legal firms, accounting firms, investment banks and other lenders that represent companies within our Target Industries. Our Advisor has been the sole or lead originator in substantially all transactions in which the funds it manages have invested.

Disciplined and balanced underwriting and portfolio management.   We use a disciplined underwriting process that includes obtaining information validation from multiple sources, extensive knowledge of our Target Industries, comparable industry valuation metrics and sophisticated financial analysis related to development-stage companies. Our Advisor’s due diligence on investment prospects includes obtaining and evaluating information on the prospective portfolio company’s technology, market opportunity, management team, fund raising history, investor support, valuation considerations, financial condition and projections. We seek to balance our investment portfolio to reduce the risk of down market cycles associated with any particular industry or sector, development-stage or geographic area by quarterly reviewing each criteria and, in the event there is an overconcentration, seeking investment opportunities to reduce such overconcentration. Our Advisor employs a “hands on” approach to portfolio management requiring private portfolio companies to provide monthly financial information and to participate in regular updates on performance and future plans. For public companies, our Advisor typically relies on publicly reported quarterly financials.

Use of leverage.   We use leverage to increase returns on equity through our revolving credit facility, or the Key Facility, provided by KeyBank National Association, or Key, and through our unsecured 6.25% notes due 2022, or the 2022 Notes. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations — Liquidity and capital resources” in our most recently filed Annual Report on Form 10-K for additional information about our use of leverage. In addition, we may issue additional debt securities or preferred stock in one or more series in the future, the specific terms of which will be described in the particular prospectus supplement relating to that series. See “Description of Debt Securities That We May Issue” and “Description of Preferred Stock That We May Issue” for additional information about the debt securities or preferred stock we may issue.
Market opportunity
We focus our investments primarily in four key industries of the emerging technology market: technology, life science, healthcare information and services and cleantech. The technology sectors we focus on include communications, networking, data storage, software, cloud computing, semiconductor, internet and media and consumer-related technologies. The life science sectors we focus on include biotechnology, drug discovery, drug delivery, bioinformatics and medical devices. The healthcare information and services sectors we focus on include diagnostics, electronic medical record services and software and other healthcare related services and technologies that improve efficiency and quality of administered healthcare. The cleantech sectors we focus on include alternative energy, power management, energy efficiency, green building materials and waste recycling. We refer to all of these companies as “technology-related” companies because the companies are developing or offering goods and services to businesses and consumers which utilize scientific knowledge, including techniques, skills, methods, devices and processes, to solve problems. We intend, under normal market conditions, to invest at least 80% of the value of our total assets in such companies.

TABLE OF CONTENTS
We believe that Venture Lending has the potential to achieve enhanced returns that are attractive notwithstanding the high degree of risk associated with lending to development-stage companies. Potential benefits include:

interest rates that typically exceed rates that would be available to portfolio companies if they could borrow in traditional commercial financing transactions;

the debt investment support provided by cash proceeds from equity capital invested by venture capital and private equity firms or access to public equity markets to access capital;

relatively rapid amortization of principal;

senior ranking to equity and collateralization of debt investments to minimize potential loss of capital; and

potential equity appreciation through warrants.
We believe that Venture Lending also provides an attractive financing source for portfolio companies, their management teams and their equity capital investors, as it:

is typically less dilutive to the equity holders than additional equity financing;

extends the time period during which a portfolio company can operate before seeking additional equity capital or pursuing a sale transaction or other liquidity event; and

allows portfolio companies to better match cash sources with uses.
Competitive strengths
We believe that we, together with our Advisor, possess significant competitive strengths, which include the following:

Consistently execute commitments and close transactions.   Our Advisor and its senior management and investment professionals have an extensive track record of originating, underwriting and managing Venture Loans. Our Advisor and its predecessor have directly originated, underwritten and managed Venture Loans with an aggregate original principal amount over $1.5 billion to more than 235 companies since operations commenced in 2004.

Robust direct origination capabilities.   Our Advisor has significant experience originating Venture Loans in our Target Industries. This experience has given our Advisor a deep knowledge of our Target Industries and an extensive base of transaction sources and references.

Highly experienced and cohesive management team.   Our Advisor’s senior management team of experienced professionals has been together since our inception. This consistency allows companies, their management teams and their investors to rely on consistent and predictable service, loan products and terms and underwriting standards.

Relationships with venture capital and private equity investors.   Our Advisor has developed strong relationships with venture capital and private equity firms and their partners.

Well-known brand name.   Our Advisor has originated Venture Loans to more than 235 companies in our Target Industries under the “Horizon Technology Finance” brand.
Our portfolio
From the commencement of operations of Compass Horizon on March 4, 2008 through March 31, 2019, we funded 171 portfolio companies and invested $1.1 billion in debt investments. As of March 31, 2019, our debt investment portfolio consisted of 35 debt investments with an aggregate fair value of $235.3 million. As of March 31, 2019, 100.0%, or $235.3 million, of our debt investment portfolio at fair value consisted of Senior Term Loans. As of March 31, 2019, our net assets were $156.4 million, and all of our debt investments were secured by all or a portion of the tangible and intangible assets of the applicable portfolio company. The debt investments in our portfolio are generally not rated by any rating agency. If the individual debt investments in our portfolio were rated, they would be rated below “investment grade”. Debt investments that are unrated or rated below investment grade are sometimes referred to as “junk bonds” and have predominantly speculative characteristics with respect to the issuer’s capacity to pay interest and repay principal.

TABLE OF CONTENTS
For the three months ended March 31, 2019, our dollar-weighted annualized yield on average debt investments (excluding any yield from warrants, equity, other investments and Horizon Secured Loan Fund I LLC, or HSLFI, a joint venture formed with Arena Sunset SPV, LLC, or Arena) was 14.4%. We calculate the dollar-weighted yield on average debt investments for any period as (1) total investment income (excluding income from HSLFI) during the period divided by (2) the average of the fair value of debt investments outstanding on (a) the last day of the calendar month immediately preceding the first day of the period and (b) the last day of each calendar month during the period. The dollar-weighted annualized yield on average debt investments is higher than what investors will realize because it does not reflect our expenses or any sales load paid by investors.
For the three months ended March 31, 2019, our investment portfolio (including any yield from warrants, equity, other investments and HSLFI) had an overall total yield of 13.1%. We calculate the dollar-weighted yield on average investments for any period as (1) total investment income during the period divided by (2) the average of the fair value of investments outstanding on (a) the last day of the calendar month immediately preceding the first day of the period and (b) the last day of each calendar month during the period. The dollar-weighted annualized yield on average investments is higher than what investors will realize because it does not reflect our expenses or any sales load paid by investors.
As of March 31, 2019, our debt investments had a dollar-weighted average term of 47 months from inception and a dollar-weighted average remaining term of 35 months. As of March 31, 2019, substantially all of our debt investments had an original committed principal amount of between $3 million and $20 million, repayment terms of between 10 and 60 months and bore current pay interest at annual interest rates of between 9% and 15%.
For the three months ended March 31, 2019, our total return based on market value was 7.5%. Total return based on market value is calculated as (x) the sum of  (i) the closing sales price of our common stock on the last day of the period plus (ii) the aggregate amount of distributions paid per share during the period, less (iii) the closing sales price of our common stock on the first day of the period, divided by (y) the closing sales price of our common stock on the first day of the period.
In addition to our debt investments, as of March 31, 2019, we held warrants to purchase stock, predominantly preferred stock, in 68 portfolio companies, equity positions in eight portfolio companies and success fee arrangements in nine portfolio companies.
On June, 1 2018, we and Arena formed a joint venture, HSLFI, to make investments, either directly or indirectly through subsidiaries, primarily in the form of secured loans to development-stage companies in our Target Industries. HSLFI was formed as a Delaware limited liability company and is not consolidated by either us or Arena for financial reporting purposes. Investments held by HSLFI are measured at fair value.

TABLE OF CONTENTS
OFFERINGS
We may offer, from time to time, up to $250,000,000 of our common stock, preferred stock, subscription rights, debt securities and/or warrants representing rights to purchase shares of our common stock, preferred stock or debt securities on terms to be determined at the time of the offering. Any debt securities, preferred stock, warrants and subscription rights offered by means of this prospectus may be convertible or exchangeable into shares of our common stock, on terms to be determined at the time of the offering. We will offer our securities at prices and on terms to be set forth in one or more supplements to this prospectus.
We may offer our securities directly to one or more purchasers, including existing stockholders in a rights offering, through agents that we designate from time to time or to or through underwriters or dealers. The prospectus supplement relating to each offering will identify any agents or underwriters involved in the sale of our securities and will set forth any applicable purchase price, fee, commission or discount arrangement between us and our agents or underwriters or among our underwriters or the basis upon which such amount may be calculated. See “Plan of Distribution.” We may not sell any of our securities through agents, underwriters or dealers without delivery of a prospectus supplement describing the method and terms of the offering of our securities.
Set forth below is additional information regarding offerings of our securities:
Use of proceeds
We intend to use the net proceeds from selling our securities to make new investments in portfolio companies in accordance with our investment objective and strategies as described in this prospectus and for working capital and general corporate purposes.
Listing
Our common stock is traded on Nasdaq under the symbol “HRZN.” Our 2022 Notes trade on the New York Stock Exchange, or NYSE, under the ticker symbol “HTFA.”
Distributions
We intend to continue to pay monthly distributions to our stockholders out of assets legally available for distribution. Our distributions, if any, will be determined by our Board. Our ability to declare distributions depends on our earnings, our overall financial condition (including our liquidity position), maintenance of RIC status and such other factors as our Board may deem relevant from time to time.
To the extent our taxable earnings fall below the total amount of our distributions for any given fiscal year, a portion of those distributions may be deemed to be a return of capital to our common stockholders for U.S. federal income tax purposes. Thus, the source of a distribution to our stockholders may be the original capital invested by the stockholder rather than our income or gains. Stockholders should read any written disclosure accompanying a distribution payment carefully and should not assume that the source of any distribution is our ordinary income or gains.
Taxation
We have elected to be treated as a RIC. Accordingly, we generally will not incur corporate-level income taxes on any investment company taxable income determined without regard to any deductions for dividends paid and net capital gains that we distribute as dividends for U.S. federal income tax purposes to our stockholders. To maintain RIC tax treatment, we must meet specified source-of-income and asset diversification requirements and distribute annually an amount generally equal to at least 90% of our investment

TABLE OF CONTENTS
company taxable income, determined without regard to any deduction for dividends paid.
Leverage
We borrow funds to make additional investments. We use this practice, which is known as “leverage,” to attempt to increase returns to our stockholders, but it involves significant risks. See “Risk Factors” in our annual, quarterly and other reports filed with the SEC from time to time. With certain limited exceptions, we are only allowed to borrow amounts such that our asset coverage, as defined in the 1940 Act, after such borrowing equals at least 150%, subject to certain disclosure requirements.
Trading at a discount
Shares of closed-end investment companies, including BDCs, 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.
Dividend Reinvestment Plan
We have adopted a DRIP for our stockholders. The dividend reinvestment plan is an “opt out” DRIP. As a result, distributions to our stockholders are automatically reinvested in additional shares of our common stock, unless a stockholder specifically “opts out” of the DRIP so as to receive cash distributions. Stockholders who receive distributions in the form of stock will generally be subject to the same federal, state and local tax consequences as stockholders who elect to receive their distributions in cash. See “Dividend Reinvestment Plan.”
Sales of common stock below net asset value
In the event we offer common stock or warrants or rights to acquire such common stock, the offering price per share of our common stock less any underwriting commissions or discounts will not be less than the net asset value per share of our common stock at the time we make the offering except (1) in connection with the exercise of certain warrants, options or rights whose issuance has been approved by our stockholders at an exercise or conversion price not less than the market value of our common stock at the date of issuance (or, if no such market value exists, the net asset value per share of our common stock as of such date); (2) to the extent such an offer or sale is approved by stockholders holding a majority of our outstanding securities and our Board; or (3) under such other circumstances as may be permitted under the 1940 Act or by the SEC. For purposes of  (2) above, a “majority” of outstanding securities is defined in the 1940 Act as (i) 67% or more of the voting securities present at a stockholders’ meeting if the holders of more than 50% of our outstanding voting securities are present or represented by proxy; or (ii) 50% of our outstanding voting securities, whichever is less.
Certain anti-takeover provisions
Our certificate of incorporation and bylaws, as well as certain statutory and regulatory requirements, contain certain provisions that may have the effect of discouraging a third party from making an acquisition proposal for us. These

TABLE OF CONTENTS
anti-takeover provisions may inhibit a change in control in circumstances that could give the holders of our common stock the opportunity to realize a premium over the market price for our common stock. See “Description of Common Stock That We May Issue.”
Investment Management Agreement
Under an amended and restated investment management agreement, or the Investment Management Agreement, subject to the overall supervision of our Board, our Advisor manages our day-to-day operations and provides investment advisory services to us. For providing these services, our Advisor receives a base management fee from us, paid monthly in arrears, at an annual rate of 2.00% of  (i) our gross assets, including any assets acquired with the proceeds of leverage less (ii) assets consisting of cash and cash equivalents. From and after October 31, 2018, the first date on which the reduced asset coverage requirements in Section 61(a)(2) of the 1940 Act applied to the Company, the base management fee is calculated at an annual rate of 2.00% of the Company’s gross assets (less cash and cash equivalents) including any assets acquired with the proceeds of leverage; provided, that, to the extent the Company’s gross assets (less cash and cash equivalents) exceed $250 million, the base management fee on the amount of such excess over $250 million is calculated at an annual rate of 1.60% of the Company’s gross assets (less cash and cash equivalents) including any assets acquired with the proceeds of leverage.
The Investment Management Agreement also provides that our Advisor may be entitled to an incentive fee under certain circumstances. The incentive fee has two parts, which are independent of each other, with the result that one part may be payable even if the other is not. Under the first part, subject to a “Fee Cap and Deferral Mechanism”, we pay our Advisor quarterly in arrears 20.00% of Pre-Incentive Fee Net Investment Income (as defined below) which exceeds 1.75% (7.00% annualized) of our net assets at the end of the immediately preceding calendar quarter, subject to a “catch-up” feature.
For this purpose, “Pre-Incentive Fee Net Investment Income” means interest income, dividend income and any other income (including any other fees (other than fees for providing managerial assistance), such as commitment, origination, structuring, diligence and consulting fees or other fees received from portfolio companies) accrued during the calendar quarter, minus operating expenses for the quarter (including the base management fee, expenses payable under the Administration Agreement (as defined below), and any interest expense and any dividends paid on any issued and outstanding preferred stock, but excluding the incentive fee).
The incentive fee on Pre-Incentive Fee Net Investment Income is subject to a fee cap and deferral mechanism which is determined based upon a look-back period of up to three years and is expensed when incurred. For this purpose,
8

TABLE OF CONTENTS
the look-back period for the incentive fee based on Pre-Incentive Fee Net Investment Income, or the Incentive Fee Look-back Period, includes the relevant calendar quarter and the 11 preceding full calendar quarters. Each quarterly incentive fee payable on Pre-Incentive Fee Net Investment Income is subject to a cap, or the Incentive Fee Cap, and a deferral mechanism through which the Advisor may recoup a portion of such deferred incentive fees, or collectively, the Incentive Fee Cap and Deferral Mechanism. The Incentive Fee Cap is equal to (a) 20.00% of Cumulative Pre-Incentive Fee Net Return (as defined below) during the Incentive Fee Look-back Period less (b) cumulative incentive fees of any kind paid to the Advisor during the Incentive Fee Look-back Period. To the extent the Incentive Fee Cap is zero or a negative value in any calendar quarter, the Company will not pay an incentive fee on Pre-Incentive Fee Net Investment Income to the Advisor in that quarter. To the extent that the payment of incentive fees on Pre-Incentive Fee Net Investment Income is limited by the Incentive Fee Cap, the payment of such fees will be deferred and paid in subsequent calendar quarters up to three years after their date of deferment, subject to certain limitations, which are set forth in the Investment Management Agreement. We only pay incentive fees on Pre-Incentive Fee Net Investment Income to the extent allowed by the Incentive Fee Cap and Deferral Mechanism. Cumulative Pre-Incentive Fee Net Return during any Incentive Fee Look-back Period means the sum of (a) Pre-Incentive Fee Net Investment Income and the base management fee for each calendar quarter during the Incentive Fee Look-back Period and (b) the sum of cumulative realized capital gains and losses, cumulative unrealized capital appreciation and cumulative unrealized capital depreciation during the applicable Incentive Fee Look-back Period.
Under the second part of the incentive fee, we pay our Advisor at the end of each calendar year 20.00% of our realized capital gains, if any, from October 28, 2010 through the end of that calendar year, computed net of all realized capital losses and all unrealized capital depreciation on a cumulative basis through the end of such year, less all previous amounts paid in respect of the capital gain incentive fee. The second part of the incentive fee is not subject to any minimum return to stockholders. The Investment Management Agreement may be terminated by either party without penalty by delivering written notice to the other party upon not more than 60 days’ written notice. See “Business — Investment Management Agreement” in our most recently filed Annual Report on Form 10-K.
Administration Agreement
We reimburse our Administrator for the allocable portion of overhead and other expenses incurred by our Administrator in performing its obligations under an administration agreement, or the Administration Agreement, including furnishing rent, the fees and expenses associated with performing compliance functions and our allocable portion of the costs of

TABLE OF CONTENTS
FEES AND EXPENSES
The following table is intended to assist you in understanding the costs and expenses that an investor will bear directly or indirectly. However, we caution you that some of the percentages indicated in the table below are estimates and may vary. The following table and example should not be considered a representation of our future expenses. Actual expenses may be greater or less than shown. Except where the context suggests otherwise, whenever this prospectus contains a reference to fees or expenses paid by “you” or “us” or that “we” will pay fees or expenses, stockholders will indirectly bear such fees or expenses as investors in the Company.

In the event that securities to which this prospectus relates are sold to or through underwriters or agents, a corresponding prospectus supplement will disclose the applicable sales load.
(2)
In the event that we conduct an offering of any of our securities, a corresponding prospectus supplement will disclose the estimated offering expenses because they will be ultimately borne by the stockholders.
(3)
The expenses associated with the DRIP are included in “Other Expenses” in the table. See “Dividend Reinvestment Plan.”
(4)
Net Assets Attributable to Common Stock equal estimated average net assets for the next twelve months and is based on our net assets at March 31, 2019.
(5)
Our base management fee under the Investment Management Agreement is based on our gross assets, less cash and cash equivalents, which includes assets acquired using leverage, including any leverage incurred under this prospectus, and is payable monthly in arrears. The management fee referenced in the table above is based on our gross assets, less cash and cash equivalents, of  $273 million as of March 31, 2019 and includes $13 million of assets estimated to be acquired over the next twelve months using leverage, which management estimates will be in the amount of  $13 million. See “Business — Investment Management Agreement” in our most recently filed Annual Report on Form 10-K.
(6)
Our incentive fee payable under the Investment Management Agreement consists of two parts:
The first part, which is payable quarterly in arrears, subject to a Fee Cap and Deferral Mechanism, equals 20.00% of the excess, if any, of our Pre-Incentive Fee Net Investment Income over a 1.75% quarterly (7.00% 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 Advisor receives no incentive fee until our net investment income equals the hurdle rate of 1.75% but then receives, as a “catch-up,” 100% 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 2.1875% quarterly (8.75% annualized). The effect of this provision is that, if Pre-Incentive Fee Net Investment
11

TABLE OF CONTENTS
Income exceeds 2.1875% in any calendar quarter, our Advisor will receive 20.00% of our Pre-Incentive Fee Net Investment Income as if a hurdle rate did not apply. The first part of the incentive fee is computed and paid on income that may include interest that is accrued but not yet received in cash.
The second part of the incentive fee equals 20.00% of our Incentive Fee Capital Gains, if any. Incentive Fee Capital Gains are our realized capital gains on a cumulative basis from inception through the end of each calendar year, computed net of all realized capital losses and unrealized capital depreciation on a cumulative basis, less the aggregate amount of any previously paid capital gain incentive fees. The second part of the incentive fee is payable, in arrears, at the end of each calendar year (or upon termination of the Investment Management Agreement, as of the termination date). For a more detailed discussion of the calculation of this fee, see “Investment Management and Administration Agreements — Investment Management Agreement.”
The incentive payable to our Advisor represents our estimated annual expense incurred under the first part of the incentive fee payable under the Investment Management Agreement over the next twelve months. As of March 31, 2019, our cumulative realized capital gains and unrealized capital appreciation did not exceed our cumulative realized capital losses and unrealized capital depreciation. Given our strategy of investing primarily in Venture Loans, which are fixed-income assets, we believe it is unlikely that our cumulative realized capital gains and unrealized capital appreciation will exceed our cumulative realized capital losses and unrealized capital depreciation in the next twelve months. Consequently, we do not expect to incur any Incentive Fee Capital Gains during the next twelve months. As we cannot predict the occurrence of any capital gains from the portfolio, we have assumed no Incentive Fee Capital Gains.
(7)
Interest payments on borrowed funds represent our estimated annual interest payments on borrowed funds based on current debt levels as adjusted for projected increases in debt levels over the next twelve months. We may issue additional debt securities pursuant to this registration statement. In the event we were to issue additional debt securities, our borrowing costs, and correspondingly our total annual expenses, including, in the case of such preferred stock, our base management fee as a percentage of our net assets attributable to common stock, would increase.
(8)
“Other Expenses” includes our overhead expenses, including payments under the Administration Agreement, based on our allocable portion of overhead and other expenses incurred by the Administrator in performing its obligations under the Administration Agreement. See “Business — Administration Agreement” in our most recently filed Annual Report on Form 10-K. “Other Expenses” also includes the ongoing administrative expenses to the independent accountants and legal counsel of the Company and compensation of independent directors and are based on estimated amounts to be incurred during the current fiscal year.
(9)
Our stockholders indirectly bear the expenses of underlying funds or other investment vehicles that would be investment companies under Section 3(a) of the 1940 Act but for the exceptions to that definition provided for in Section 3(c)(1) and 3(c)(7) of the 1940 Act, or Acquired Funds, in which we invest.
Specifically, our stockholders indirectly bear the expenses of our investment in Horizon Secured Loan Fund I, or HSLFI. No management fee is paid by HSLFI. Included in the expenses indirectly borne by our investment is HSLFI are interest expense, professional fees, as well as bank and custody fees. Future fees and expenses for Acquired Funds, including HSLFI, may be substantially higher or lower because certain fees and expenses are based on performance of such Acquired Funds, which may fluctuate over time.
(10)
“Total Annual Expenses” as a percentage of consolidated net assets attributable to common stock are higher than the total annual expenses percentage would be for a company that is not leveraged. We borrow money to leverage our net assets and increase our total assets. The SEC requires that the “Total Annual Expenses” percentage be calculated as a percentage of net assets (defined as total assets less indebtedness and after taking into account any incentive fees payable during the period), rather than the total assets, including assets that have been funded with borrowed monies.

TABLE OF CONTENTS
Example
The following example demonstrates the projected dollar amount of total cumulative expenses that would be incurred over various periods with respect to a hypothetical investment in our common stock. 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. In calculating the following expense amounts, we have assumed that our annual operating expenses remain at the levels set forth in the table above. In the event that shares to which this prospectus relates are sold to or through underwriters or agents, a corresponding prospectus supplement will restate this example to reflect the applicable sales load and estimated offering expenses.

You would pay the following expenses on a
$1,000 investment, assuming a 5% annual
return (assumes no return from net
realized capital gains or net unrealized
capital appreciation)
$ 137 $ 374 $ 568 $ 915
The example and the expenses in the tables above should not be considered a representation of our future expenses, and actual expenses may be greater or lesser than those shown.
While the example assumes, as required by the applicable rules of the SEC, a 5% annual return, our performance will vary and may result in a return greater or less than 5%. The incentive fee under the Investment Management Agreement is unlikely to be significant assuming a 5% annual return and is not included in the example. This illustration assumes that we will not realize any capital gains (computed net of all realized capital losses and unrealized capital depreciation) in any of the indicated time periods. 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 distributions to our common stockholders and our expenses would likely be higher.
The following example demonstrates the projected dollar amount of total cumulative expenses that would be incurred over various periods with respect to a hypothetical investment in our common stock assuming a 5% annual return derived entirely from capital gains.

You would pay the following expenses on a

$ 126 $ 348 $ 536 $ 886
See “Business — Investment Management Agreement” in our most recently filed Annual Report on Form 10-K for additional information regarding the calculation of incentive fees.
In addition, while the examples assume reinvestment of all dividends and other distributions at net asset value, or NAV, participants in our DRIP 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. This price may be at, above or below NAV. See “Dividend Reinvestment Plan” for additional information regarding our DRIP.

TABLE OF CONTENTS
Risk Factors
Investing in our securities involves a high degree of risk. Before deciding whether to invest in our securities, you should carefully consider the risks and uncertainties described in the section titled “Risk Factors” in the applicable prospectus supplement and any related free writing prospectus, and discussed in the section titled “Risk Factors” in our most recent Annual Report on Form 10-K, as well as any amendments reflected in subsequent filings with the SEC, which are incorporated by reference into this prospectus in their entirety, together with other information in this prospectus, the documents incorporated by reference, and any free writing prospectus that we may authorize for use in connection with this offering. The risks described in these documents are not the only ones we face. Additional risks and uncertainties that we are unaware of, or that we currently believe are not material, may also become important factors that adversely affect our business. Past financial performance may not be a reliable indicator of future performance, and historical trends should not be used to anticipate results or trends in future periods. If any of these risks actually occurs, our business, reputation, financial condition, results of operations, revenue, and future prospects could be seriously harmed. This could cause our net asset value and trading price of our securities to decline, resulting in a loss of all or part of your investment. Please also read carefully the section titled “Cautionary Statement Regarding Forward-Looking Statements.”

TABLE OF CONTENTS
USE OF PROCEEDS
Unless otherwise specified in any applicable prospectus supplement or in any free writing prospectus we have authorized for use in connection with a specific offering, we intend to use the net proceeds from the sale of our securities for investment in portfolio companies in accordance with our investment objective and strategies and for working capital and general corporate purposes. We may also use a portion of the net proceeds from the sale of our securities to repay amounts outstanding under the Key Facility, which bore an annual interest rate of 5.74% (i.e., one-month LIBOR plus 3.25% per annum, with a LIBOR floor of 0.75%) as of March 31, 2019. We may request advances under the Key Facility until April 6, 2021 and all outstanding advances are due and payable on April 6, 2023. We may also use a portion of the net proceeds to redeem the 2022 Notes after they are subject to optional redemption in September 2019. The 2022 Notes bear interest at an annual rate of 6.25% and otherwise mature on September 15, 2022. We estimate that it will take up to six months for us to substantially invest the net proceeds of any offering made pursuant to this prospectus, depending on the availability of attractive opportunities and market conditions. However, we can offer no assurances that we will be able to achieve this goal.
Pending such use, we will invest the remaining net proceeds of this offering primarily in cash, cash equivalents, U.S. government securities and high-quality debt investments that mature in one year or less from the date of investment. These temporary investments may have lower yields than our other investments and, accordingly, may result in lower distributions, if any, during such period. See “Business — Regulation — Temporary Investments” in our most recently filed Annual Report on Form 10-K for additional information about temporary investments we may make while waiting to make longer-term investments in pursuit of our investment objective.

COMMON STOCK AND DISTRIBUTIONS
Our common stock is traded on Nasdaq, under the symbol “HRZN.” The last reported price for our common stock on June 19, 2019 was $11.69 per share. which represented a 1% premium to NAV per share. As of June 19, 2019 we had 16 stockholders of record, which did not include stockholders for whom shares are held in nominee or “street” name.
Shares of BDCs may trade at a market price that is less than the NAV that is attributable to those shares. The possibility that our shares of common stock will trade at a discount from NAV or at a premium that is unsustainable over the long term is separate and distinct from the risk that our NAV will decrease. It is not possible to predict whether our shares will trade at, above or below NAV in the future.
Issuer Purchases of Equity Securities
On April 26, 2019, our Board extended a previously authorized stock repurchase plan which allows us to repurchase up to $5.0 million of our outstanding common stock. Unless extended by our Board, the repurchase program will expire on the earlier of June 30, 2020 and the repurchase of  $5.0 million of common stock. During the quarter ended December 31, 2018, we did not repurchase any shares of our common stock. During the three months ended March 31, 2019, we did not repurchase any shares of our common stock. From the inception of the stock repurchase program through March 31, 2019, we repurchased 167,465 shares of our common stock at an average price of  $11.22 on the open market at a total cost of  $1.9 million.
Any shares repurchased by us may have the effect of maintaining the market price of our common stock or retarding a decline in the market price of the common stock, and, as a result, the price of our common stock may be higher than the price that otherwise might exist in the open market. In addition, as any shares repurchased pursuant to the stock repurchase plan will be purchased at a price below the NAV per share as reported in our most recent financial statements, share repurchases may have the effect of increasing our NAV per share.
Distributions
We intend to continue making monthly distributions to our stockholders. The timing and amount of our monthly distributions, if any, is determined by our Board. Any distributions to our stockholders are declared out of assets legally available for distribution. We monitor available net investment income to determine if a tax return of capital may occur for the fiscal year. To the extent our taxable earnings fall below the total amount of our distributions for any given fiscal year, a portion of those distributions may be considered a return of capital to our common stockholders for U.S. federal income tax purposes. Thus, the source of distribution to our stockholders may be the original capital invested by the stockholder rather than our income or gains. Stockholders should read any written disclosure accompanying a distribution payment carefully and should not assume that the source of any distribution is our ordinary income or gains.
In order to qualify to be subject to tax as a RIC, we must meet certain source-of-income, asset diversification and annual distribution requirements. Generally, in order to qualify as a RIC, we must derive at least 90% of our gross income during each tax year from dividends, interest, payments with respect to certain securities, loans, gains from the sale or other disposition of stock, securities or foreign currencies, or other income derived with respect to our business of investing in stock or other securities. We must also meet certain asset diversification requirements at the end of each quarter of each tax year. Failure to meet these diversification requirements on the last day of a quarter may result in us having to dispose of certain investments quickly in order to prevent the loss of RIC status. Any such dispositions could be made at disadvantageous prices or times, and may cause us to incur substantial losses.
In addition, in order to be eligible for the special tax treatment accorded to RICs and to avoid the imposition of corporate level tax on the income and gains we distribute to our stockholders, each tax year we are required under the Code to distribute as dividends of an amount generally at least 90% of our investment company taxable income, determined without regard to any deduction for dividends paid to our stockholders. We refer to such amount as the Annual Distribution Requirement. Additionally, we must distribute, in respect of each calendar year, dividends of an amount generally at least equal to the sum of

TABLE OF CONTENTS
98% of our calendar year net ordinary income (taking into account certain deferrals and elections); 98.2% of our capital gain net income (adjusted for certain ordinary losses) for the one year period ending on October 31 of such calendar year; and any net ordinary income or capital gain net income for preceding years that was not distributed during such years and on which we previously did not incur any U.S. federal income tax in order to avoid the imposition of a 4% U.S. federal excise tax. If we fail to qualify as a RIC for any reason and become subject to corporate income tax, the resulting corporate income taxes could substantially reduce our net assets, the amount of income available for distribution and the amount of our distributions. Such a failure would have a material adverse effect on us and our stockholders. In addition, we could be required to recognize unrealized gains, incur substantial taxes and interest and make substantial distributions in order to re-qualify as a RIC. We cannot assure stockholders that they will receive any distributions.
Depending on the level of taxable income earned in a tax year, we may choose to carry forward taxable income in excess of current year distributions into the next tax year and pay a 4% U.S. federal excise tax on such undistributed income. Distributions of any such carryover taxable income must be made through a distribution declared as of the earlier of the filing date of the corporate income tax return related to the tax year in which such taxable income was generated or the 15th day of the ninth month following the end of such tax year, in order to count towards the satisfaction of the Annual Distribution Requirement for the tax year in which such taxable income was generated. 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 may be prohibited from making distributions if doing so causes us to fail to maintain the asset coverage stipulated by the 1940 Act or if distributions are limited by the terms of any of our borrowings. See “Material U.S. Federal Income Tax Considerations.”
We have adopted an “opt out” DRIP for our common stockholders. As a result, if we make a distribution, then stockholders’ cash distributions are automatically reinvested in additional shares of our common stock, unless they specifically opt out of the DRIP. If a stockholder opts out, that stockholder receives cash distributions. Although distributions paid in the form of additional shares of common stock are generally subject to U.S. federal, state and local taxes, stockholders participating in our DRIP do not receive any corresponding cash distributions with which to pay any such applicable taxes. We may use newly issued shares to implement the DRIP, or we may purchase shares in the open market in connection with our obligations under the DRIP.

RATIO OF EARNINGS TO FIXED CHARGES
For the three months ended March 31, 2019 and the years ended December 31, 2018, 2017, 2016, 2015 and 2014, our ratios of earnings to fixed charges, computed as set forth below, were as follows:

2015
2014
Earnings to Fixed Charges(1)
2.5 3.1 2.9 0.1 3.1 2.8
For purposes of computing the ratios of earnings to fixed charges, earnings represent net increase in net assets resulting from operations plus (or minus) income tax expense (benefit) including excise tax expense and fixed charges. Fixed charges include interest expense, which includes amortization of debt issuance costs and non-use fees.
(1)
Earnings include net realized and unrealized gains or losses. Net realized and unrealized gains or losses can vary substantially from period to period.
Excluding the net unrealized gains or losses, the earnings to fixed charges ratio would be 3.1 for the three months ended March 31, 2019, 3.3 for the year ended December 31, 2018, (0.7) for the year ended December 31, 2017, 2.6 for the year ended December 31, 2016, 3.1 for the year ended December 31, 2015 and 1.8 for the year ended December 31, 2014.
Excluding the net realized and unrealized gains or losses, the earnings to fixed charges ratio would be 2.6 for the three months ended March 31, 2019, 3.2 for the year ended December 31, 2018, 3.4 for the year ended December 31, 2017, 3.9 for the year ended December 31, 2016, 3.4 for the year ended December 31, 2015 and 2.2 for the year ended December 31, 2014.

TABLE OF CONTENTS
PORTFOLIO COMPANIES
The following table sets forth certain information as of March 31, 2019 for each portfolio company in which we had a debt, equity or other investment. Other than these investments, our only relationships with our portfolio companies involve the managerial assistance we may separately provide to our portfolio companies, such services being ancillary to our investments, and the board observer or participation rights we may receive in connection with our investment. We do not “control” any of our portfolio companies, each as defined in the 1940 Act. In general, under the 1940 Act, we would “control” a portfolio company if we owned more than 25% of its voting securities.

Debt investments are at variable rates for the term of the debt investment, unless otherwise indicated.

ETPs are contractual fixed-interest payments due in cash at the maturity date of the applicable debt investment, including upon any prepayment, and are a fixed percentage of the original principal balance of the debt investments unless otherwise noted. Interest will accrue during the life of the debt investment on each ETP and will be recognized as non-cash income until it is actually paid. Therefore, a portion of the incentive fee the Company may pay its Advisor will be based on income that the Company has not yet received in cash.

On June 1, 2018, the Company entered into an agreement with Arena Sunset SPV, LLC (“Arena”) to co-invest through Horizon Secured Loan Fund I (“HSLFI”), a joint venture, which is expected to make investments, either directly or indirectly through subsidiaries, primarily in the form of secured loans to development-stage companies in the technology, life science, healthcare information and services and cleantech industries. All HSLFI investment decisions require unanimous approval of a quorum of HSLFI’s board of managers. Although the Company owns more than 25% of the voting securities of HSLFI, the Company does not have sole control over significant actions of HSLFI for purposes of the 1940 Act or otherwise.

TABLE OF CONTENTS
DIVIDEND REINVESTMENT PLAN
We have adopted a DRIP that provides for reinvestment of our cash distributions and other distributions on behalf of our stockholders, unless a stockholder elects to receive cash as provided below. As a result, if our Board declares a cash distribution, then our stockholders who have not “opted out” of our DRIP have their cash distribution automatically reinvested in additional shares of our common stock, rather than receiving the cash distribution.
No action is required on the part of a registered stockholder to have their cash distribution reinvested in shares of our common stock. A registered stockholder may elect to receive an entire distribution in cash by notifying Computershare Shareowner Services, the plan administrator and our transfer agent and registrar, in writing so that such notice is received by the plan administrator no later than 10 days prior to the record date for distributions to stockholders. The plan administrator sets up an account for shares acquired through the plan for each stockholder who has not elected to receive dividends or other distributions in cash and holds such shares in non-certificated form. Upon request by a stockholder participating in the plan, received in writing not less than 10 days prior to the record date, the plan administrator will, instead of crediting shares to the participant’s account, issue a certificate registered in the participant’s name for the number of whole shares of our common stock and a check for any fractional share.
Those stockholders whose shares are held by a broker or other financial intermediary may receive distributions in cash by notifying their broker or other financial intermediary of their election.
We intend to use primarily newly issued shares to implement the plan, whether our shares are trading at a premium or at a discount to net asset value. However, we reserve the right to purchase shares in the open market in connection with our implementation of the plan. The number of shares to be issued to a stockholder is determined by dividing the total dollar amount of the distribution payable to such stockholder by the market price per share of our common stock at the close of regular trading on Nasdaq on the valuation date, which date shall be as close as practicable to the payment date for such distribution. Market price per share on that date will be the closing price for such shares on Nasdaq or, if no sale is reported for such day, at the average of their reported bid and asked prices. The number of shares of our common stock to be outstanding after giving effect to payment of the distribution cannot be established until the value per share at which additional shares will be issued has been determined and elections of our stockholders have been tabulated. Stockholders who do not elect to receive distributions in shares of common stock may experience accretion to the net asset value of their shares if our shares are trading at a premium at the time we issue new shares under the plan and dilution if our shares are trading at a discount. The level of accretion or discount would depend on various factors, including the proportion of our stockholders who participate in the plan, the level of premium or discount at which our shares are trading and the amount of the distribution payable to a stockholder.
There are no brokerage charges or other charges to stockholders who participate in the plan. The plan administrator’s fees under the plan are paid by us. If a participant elects by written notice to the plan administrator to have the plan administrator sell part or all of the shares held by the plan administrator in the participant’s account and remit the proceeds to the participant, the plan administrator is authorized to deduct a $15.00 transaction fee plus a $0.10 per share trading fee from the proceeds.
Stockholders who receive distributions in the form of stock are generally subject to the same federal, state and local tax consequences as are stockholders who elect to receive their distributions in cash. Any stock received in a dividend has a new holding period for tax purposes commencing on the day following the day on which the shares are credited to the U.S. stockholder’s account. See “Material U.S. Federal Income Tax Considerations.”
Participants may terminate their accounts under the plan by notifying the plan agent via its website at www.computershare.com/investor, by filling out the transaction request form located at bottom of their statement and sending it to the plan agent at c/o Computershare Shareowner Services LLC, P.O. Box 505000, Louisville, Kentucky 40233 or by calling the plan administrator at 877-373-6374.
The plan may be terminated by us upon notice in writing mailed to each participant. All correspondence concerning the plan should be directed to the plan administrator by mail at Plan Administrator c/o Computershare Shareowner Services LLC, P.O. Box 505000, Louisville, Kentucky 40233.

TABLE OF CONTENTS
If you withdraw or the plan is terminated, the plan administrator will continue to hold your shares in book-entry form unless you request that such shares be sold or issued. Upon receipt of your instructions, a certificate for each whole share in your account under the plan will be issued and you will receive a cash payment for any fraction of a share in your account.
If you hold your common stock with a brokerage firm that does not participate in the plan, you are not able to participate in the plan and any dividend reinvestment may be effected on different terms than those described above. Consult your financial advisor for more information.

TABLE OF CONTENTS
DESCRIPTION OF COMMON STOCK THAT WE MAY ISSUE
General
The following description does not purport to be complete and is subject to the provisions of our certificate of incorporation and bylaws, each of which are filed as exhibits to this registration statement. The description is qualified in its entirety by reference to our certificate of incorporation and bylaws and to applicable law. We urge you to read the applicable prospectus supplement and any related free writing prospectus that we may authorize to be provided to you related to any shares of our capital stock being offered.
Under the terms of our certificate of incorporation, our authorized common stock consists solely of 100,000,000 shares, par value $0.001 per share, of which 13,542,873 shares were outstanding as of June 19, 2019. Our common stock is traded on Nasdaq under the symbol “HRZN”. There are no outstanding options or warrants to purchase our stock. No stock has been authorized for issuance under any equity compensation plans. Under the DGCL, our stockholders generally are not personally liable for our debts or obligations.
Under the terms of our certificate of incorporation, all shares of our common stock have equal rights as to earnings, assets, distributions and voting. When they are issued, shares of our common stock will be duly authorized, validly issued, fully paid and non-assessable. Distributions may be paid to the holders of our common stock if, as and when declared by our Board out of assets legally available therefor, subject to any preferential dividend rights of outstanding preferred stock. Holders of common stock are entitled to one vote for each share held on all matters submitted to a vote of stockholders, including the election of directors, and do not have cumulative voting rights. Accordingly, holders of a majority of the shares of common stock entitled to vote in any election of directors may elect all of the directors standing for election. Upon our liquidation, dissolution or winding up, the holders of common stock are entitled to receive ratably our net assets available after the payment of all debts and other liabilities and subject to the prior rights of any outstanding preferred stock. Holders of common stock have no preemptive, subscription, redemption or conversion rights. The rights, preferences and privileges of holders of common stock are subject to the rights of the holders of any series of preferred stock which we may designate and issue in the future. In addition, holders of our common stock may participate in our DRIP.
Anti-takeover effects of provisions of our certificate of incorporation, bylaws, the DGCL and other arrangements
Certain provisions of our certificate of incorporation and bylaws, applicable provisions of the DGCL and certain other agreements to which we are a party may make it more difficult for or prevent an unsolicited third party from acquiring control of us or changing our Board and management. These provisions may have the effect of deterring hostile takeovers or delaying changes in our control or in our management. These provisions are intended to enhance the likelihood of continued stability in the composition of our Board and in the policies furnished by them and to discourage certain types of transactions that may involve an actual or threatened change in our control. The provisions also are intended to discourage certain tactics that may be used in proxy fights. These provisions, however, could have the effect of discouraging others from making tender offers for our shares and, as a consequence, they also may inhibit fluctuations in the market price of our shares that could result from actual or rumored takeover attempts.
Election of directors.   Our certificate of incorporation and bylaws provide that the affirmative vote of a plurality of all votes cast at a meeting of stockholders duly called at which a quorum is present shall be sufficient to elect a director. Under our certificate of incorporation, our Board may amend the bylaws to alter the vote required to elect directors.
Classified board of directors.   The classification of our Board and the limitations on removal of directors and filling of vacancies could have the effect of making it more difficult for a third party to acquire us, or of discouraging a third party from acquiring us. Our Board is divided into three classes, with the term of one class expiring at each annual meeting of stockholders. At each annual meeting, one class of directors is elected to a three-year term. This provision could delay for up to two years the replacement of a majority of our Board.
35

TABLE OF CONTENTS
Number of directors; vacancies; removal.   Our certificate of incorporation provides that, by amendment to our bylaws, our Board is authorized to change the number of directors without the consent of stockholders to any number between three and nine.
Our certificate of incorporation provides that, subject to the rights of any holders of preferred stock, any vacancy on our Board, however the vacancy occurs, including a vacancy due to an enlargement of our Board, may only be filled by vote of a majority of the directors then in office.
Subject to the rights of any holders of preferred stock, a director may be removed at any time at a meeting called for that purpose, but only for cause and only by the affirmative vote of the holders of at least 75% of the shares then entitled to vote for the election of the respective director.
The limitations on the ability of our stockholders to remove directors and fill vacancies could make it more difficult for a third party to acquire, or discourage a third party from seeking to acquire, control of us.
Action by stockholders.   Under our certificate of incorporation and bylaws, stockholder action can only be taken at an annual meeting or special meeting and not by written action in lieu of a meeting. This may have the effect of delaying consideration of a stockholder proposal until the next annual meeting.
Advance notice requirements for stockholder proposals and director nominations.   Our bylaws provide that with respect to an annual meeting of stockholders, nominations of persons for election to our Board and the proposal of business to be considered by stockholders may be made only (1) by or at the direction of our Board, (2) pursuant to our notice of meeting or (3) by a stockholder who is entitled to vote at the meeting and who has complied with the advance notice procedures of the bylaws. Nominations of persons for election to our Board at a special meeting may be made only (1) by or at the direction of our Board, or (2) provided that our Board has determined that directors will be elected at the meeting, by a stockholder who is entitled to vote at the meeting and who has complied with the advance notice provisions of the bylaws. The purpose of requiring stockholders to give us advance notice of nominations and other business is to afford our Board a meaningful opportunity to consider the qualifications of the proposed nominees and the advisability of any other proposed business and, to the extent deemed necessary or desirable by our Board, to inform our stockholders and make recommendations about such qualifications or business, as well as to provide a more orderly procedure for conducting meetings of stockholders. Although our bylaws do not give our Board any power to disapprove stockholder nominations for the election of directors or proposals recommending certain action, they may have the effect of precluding a contest for the election of directors or the consideration of stockholder proposals if proper procedures are not followed and of discouraging or deterring a third party from conducting a solicitation of proxies to elect its own slate of directors or to approve its own proposal without regard to whether consideration of such nominees or proposals might be harmful or beneficial to us and our stockholders.
Amendments to certificate of incorporation and bylaws.   The DGCL provides generally that the affirmative vote of a majority of the shares entitled to vote on any matter is required to amend a corporation’s certificate of incorporation or bylaws, unless a corporation’s certificate of incorporation or bylaws requires a greater percentage. Our certificate of incorporation provides that the affirmative vote of 75% of the then outstanding shares entitled to vote generally in the election of directors voting together as a single class is required to amend provisions of our certificate of incorporation relating to the classification, size and vacancies of our Board, as well as the removal of directors. However, if 6623% of the continuing directors have approved such amendment or repeal, the affirmative vote for such amendment or repeal shall be a majority of such shares. The affirmative vote of 75% of the then outstanding shares voting together as a single class is required to amend provisions of our certificate of incorporation relating to the calling of a special meeting of stockholders or the ability to amend or repeal the bylaws. Our certificate of incorporation permits our Board to amend or repeal our bylaws, provided that any amendment or repeal shall require the approval of at least 6623% of the continuing directors. The stockholders do not have the right to adopt or repeal the bylaws.
Stockholder meetings.   Our certificate of incorporation and bylaws provide that any action required or permitted to be taken by stockholders at an annual meeting may only be taken if it is properly brought before such meeting. For business to be properly brought before an annual meeting by a stockholder, the stockholder must provide timely notice to our Secretary. Notice is timely if it is delivered by a nationally

TABLE OF CONTENTS
recognized courier service or mailed by first class United States mail and received not earlier than 90 days nor more than 120 days in advance of the anniversary of the date our proxy statement was released to stockholders in connection with the previous year’s annual meeting. Action taken at a special meeting of stockholders is limited to the purposes stated in the properly provided notice of meeting. These provisions could have the effect of delaying until the next stockholder meeting actions that are favored by the holders of a majority of our outstanding voting securities.
Calling of special meetings by stockholders.   Our certificate of incorporation and bylaws provide that special meetings of the stockholders may only be called by our Board, Chairman, Chief Executive Officer or President.
Section 203 of the DGCL.   We are subject to the provisions of Section 203 of the DGCL. In general, these provisions prohibit a Delaware corporation from engaging in any business combination with any interested stockholder for a period of three years following the date that the stockholder became an interested stockholder, unless:

prior to such time, the board of directors approved either the business combination or the transaction which resulted in the stockholder becoming an interested stockholder;

upon consummation of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced; or

on or after the date the business combination is approved by the board of directors and authorized at a meeting of stockholders, by at least two-thirds of the outstanding voting stock that is not owned by the interested stockholder.
Section 203 defines “business combination” to include the following:

any merger or consolidation involving the corporation and the interested stockholder;

any sale, transfer, pledge or other disposition (in one transaction or a series of transactions) of 10% or more of either the aggregate market value of all the assets of the corporation or the aggregate market value of all the outstanding stock of the corporation involving the interested stockholder;

subject to certain exceptions, any transaction that results in the issuance or transfer by the corporation of any stock of the corporation to the interested stockholder;

any transaction involving the corporation that has the effect of increasing the proportionate share of the stock of any class or series of the corporation owned by the interested stockholder; or

the receipt by the interested stockholder of the benefit of any loans, advances, guarantees, pledges or other financial benefits provided by or through the corporation.
In general, Section 203 defines an interested stockholder as any entity or person beneficially owning 15% or more of the outstanding voting stock of the corporation and any entity or person affiliated with or controlling or controlled by any of these entities or persons.
The statute could prohibit or delay mergers or other takeover or change in control attempts and, accordingly, may discourage attempts to acquire us.
Conflict with 1940 Act.   Our bylaws provide that, if and to the extent that any provision of the DGCL or our bylaws conflict with any provision of the 1940 Act, the applicable provision of the 1940 Act will control.
Approval of certain transactions.   To convert us to an open-end investment company, to merge or consolidate us with any entity in a transaction as a result of which the governing documents of the surviving entity do not contain substantially the same anti-takeover provisions as are provided in our certificate of incorporation, to liquidate and dissolve us, or to amend any of the anti-takeover provisions discussed herein, our certificate of incorporation requires the affirmative vote of a majority of our continuing directors followed by the favorable vote of the holders of at least 75% of each affected class or
37

TABLE OF CONTENTS
series of our shares, voting separately as a class or series, unless such amendment has been approved by the holders of at least 80% of the then outstanding shares of our capital stock, voting together as a single class. If approved in the foregoing manner, our conversion to an open-end investment company could not occur until 90 days after the stockholders meeting at which such conversion was approved and would also require at least 30 days’ prior notice to all stockholders. As part of any such conversion to an open-end investment company, substantially all of our investment policies and strategies and portfolio would have to be modified to assure the degree of portfolio liquidity required for open-end investment companies. In the event of conversion, the common shares would cease to be listed on any national securities exchange or market system. Stockholders of an open-end investment company may require the company to redeem their shares at any time, except in certain circumstances as authorized by or under the 1940 Act, at their net asset value, less such redemption charge, if any, as might be in effect at the time of a redemption. You should assume that it is not likely that our Board would vote to convert us to an open-end fund.
The 1940 Act defines “a majority of the outstanding voting securities” as the lesser of a majority of the outstanding shares and 67% of a quorum of a majority of the outstanding shares. For the purposes of calculating “a majority of the outstanding voting securities” under our certificate of incorporation, each class and series of our shares vote together as a single class, except to the extent required by the 1940 Act or our certificate of incorporation, with respect to any class or series of shares. If a separate class vote is required, the applicable proportion of shares of the class or series, voting as a separate class or series, also will be required.
Our Board has determined that provisions with respect to our Board and the stockholder voting requirements described above, which voting requirements are greater than the minimum requirements under the DGCL or the 1940 Act, are in the best interest of stockholders generally.
It is a default under our Key Facility if  (i) a person or group of persons (within the meaning of the Exchange Act) acquires beneficial ownership of 20% or more of our issued and outstanding stock or (ii) during any twelve month period individuals who at the beginning of such period constituted our Board cease for any reason, other than death or disability, to constitute a majority of the directors in office. If either event were to occur, Key could accelerate our repayment obligations under, and/or terminate, our Key Facility. We urge you to read the applicable prospectus supplement and any free writing prospectus that we may authorize to be provided to you related to the common stock.
Limitations of liability and indemnification
The indemnification of our officers and directors is governed by Section 145 of the DGCL, and our certificate of incorporation and bylaws. Subsection (a) of Section 145 of the DGCL empowers a corporation to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation) by reason of the fact that the person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with such action, suit or proceeding if  (1) such person acted in good faith, (2) in a manner such person reasonably believed to be in or not opposed to the best interests of the corporation and (3) with respect to any criminal action or proceeding, such person had no reasonable cause to believe the person’s conduct was unlawful.
Subsection (b) of Section 145 of the DGCL empowers a corporation to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor by reason of the fact that the person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against expenses (including attorneys’ fees) actually and reasonably incurred by such person in connection with the defense or settlement of such action or suit if such person acted in good faith and in a manner the person reasonably believed to be in, or not opposed to, the best interests of the corporation, and except that no indemnification may be made in respect of any claim, issue or matter as to which such person has been adjudged to be liable to the corporation unless and only to the extent that the
38

TABLE OF CONTENTS
Delaware Court of Chancery or the court in which such action or suit was brought determines upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Delaware Court of Chancery or such other court deems proper.
Section 145 of the DGCL further provides that to the extent that a present or former director or officer is successful, on the merits or otherwise, in the defense of any action, suit or proceeding referred to in subsections (a) and (b) of Section 145 of the DGCL, or in defense of any claim, issue or matter therein, such person will be indemnified against expenses (including attorneys’ fees) actually and reasonably incurred by such person in connection with such action, suit or proceeding. In all cases in which indemnification is permitted under subsections (a) and (b) of Section 145 of the DGCL (unless ordered by a court), it will be made by the corporation only as authorized in the specific case upon a determination that indemnification of the present or former director, officer, employee or agent is proper in the circumstances because the applicable standard of conduct has been met by the party to be indemnified. Such determination must be made, with respect to a person who is a director or officer at the time of such determination, (1) by a majority vote of the directors who are not parties to such action, suit or proceeding, even though less than a quorum, (2) by a committee of such directors designated by majority vote of such directors, even though less than a quorum, (3) if there are no such directors, or if such directors so direct, by independent legal counsel in a written opinion or (4) by the stockholders. The statute authorizes the corporation to pay expenses incurred by an officer or director in advance of the final disposition of a proceeding upon receipt of an undertaking by or on behalf of the person to whom the advance will be made, to repay the advances if it is ultimately determined that he or she was not entitled to indemnification. Section 145 of the DGCL also provides that indemnification and advancement of expenses permitted under such Section are not to be exclusive of any other rights to which those seeking indemnification or advancement of expenses may be entitled under any bylaw, agreement, vote of stockholders or disinterested directors, or otherwise. Section 145 of the DGCL also authorizes the corporation to purchase and maintain liability insurance on behalf of its directors, officers, employees and agents regardless of whether the corporation would have the statutory power to indemnify such persons against the liabilities insured.
Our certificate of incorporation provides that our directors will not be liable to us or our stockholders for monetary damages for breach of fiduciary duty as a director to the fullest extent permitted by the DGCL. Section 102(b)(7) of the DGCL provides that the personal liability of a director to a corporation or its stockholders for breach of fiduciary duty as a director may be eliminated except for liability (1) for any breach of the director’s duty of loyalty to the corporation or its stockholders, (2) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (3) under Section 174 of the DGCL, relating to unlawful payment of distributions or unlawful stock purchases or redemption of stock or (4) for any transaction from which the director derives an improper personal benefit.
Under our certificate of incorporation, we fully indemnify any person who was or is involved in any actual or threatened action, suit or proceeding by reason of the fact that such person is or was one of our directors or officers. So long as we are regulated under the 1940 Act, the above indemnification and limitation of liability is limited by the 1940 Act or by any valid rule, regulation or order of the SEC thereunder. The 1940 Act provides, among other things, that a company may not indemnify any director or officer against liability to it or its security holders to which he or she might otherwise be subject by reason of his or her willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of his or her office unless a determination is made by final decision of a court, by vote of a majority of a quorum of directors who are disinterested, non-party directors or by independent legal counsel that the liability for which indemnification is sought did not arise out of the foregoing conduct.
We have obtained liability insurance for our directors and officers. In addition, we have entered into indemnification agreements with each of our directors and officers in order to effect the foregoing except to the extent that such indemnification would exceed the limitations on indemnification under Section 17(h) of the 1940 Act.

DESCRIPTION OF PREFERRED STOCK THAT WE MAY ISSUE
Under the terms of our certificate of incorporation, our authorized preferred stock consists of 1,000,000 shares, par value $0.001 per share, of which no shares were outstanding as of June 19, 2019, and our Board is authorized to issue shares of preferred stock in one or more series without stockholder approval. Particular terms of any preferred stock we offer will be described in the prospectus supplement relating to such preferred stock shares.
Our Board has discretion to determine the rights, preferences, privileges and restrictions, including voting rights, dividend rights, conversion rights, redemption privileges and liquidation preferences of each series of preferred stock. Every issuance of preferred stock will be required to comply with the requirements of the 1940 Act. The 1940 Act limits our flexibility as to certain rights and preferences of the preferred stock that our certificate of incorporation may provide and requires, among other things, that (1) immediately after issuance and before any distribution is made with respect to our common stock, and before any purchase of common stock is made, such preferred stock together with all other senior securities must not exceed an amount equal to 50% of our total assets (or 6623% if certain approval and disclosure requirements are met) after deducting the amount of such dividend, distribution or purchase price, as the case may be, (2) the holders of shares of preferred stock, if any are issued, must be entitled as a class to elect two directors at all times and to elect a majority of the directors if and for so long as distributions on the preferred stock are in arrears by two years or more and (3) such shares be cumulative as to distributions and have a complete preference over our common stock to payment of their liquidation preference in the event of a dissolution. Certain matters under the 1940 Act require the separate vote of the holders of any issued and outstanding preferred stock. For example, holders of preferred stock would vote separately from the holders of common stock on a proposal to cease operations as a BDC. The features of the preferred stock will be further limited by the requirements applicable to RICs under the Code. The purpose of authorizing our Board to issue preferred stock and determine its rights and preferences is to eliminate delays associated with a stockholder vote on specific issuances. The issuance of preferred stock, while providing desirable flexibility in connection with providing leverage for our investment program, possible acquisitions and other corporate purposes, could make it more difficult for a third party to acquire, or could discourage a third party from acquiring, a majority of our outstanding voting stock.
For any series of preferred stock that we may issue, our Board will determine, and the prospectus supplement relating to such series will describe:

the designation and number of shares of such series;

the rate and time at which, and the preferences and conditions under which, any distributions will be paid on shares of such series, as well as whether such distributions are participating or non-participating;

any provisions relating to convertibility or exchangeability of the shares of such series;

the rights and preferences, if any, of holders of shares of such series upon our liquidation, dissolution or winding up of our affairs;

the voting powers, if any, of the holders of shares of such series;

any provisions relating to the redemption of the shares of such series;

any limitations on our ability to pay dividends or make distributions on, or acquire or redeem, other securities while shares of such series are outstanding;

any conditions or restrictions on our ability to issue additional shares of such series or other securities;

if applicable, a discussion of certain U.S. federal income tax considerations; and

any other relative power, preferences and participating, optional or special rights of shares of such series, and the qualifications, limitations or restrictions thereof.

TABLE OF CONTENTS
The preferred stock may be either fixed rate preferred stock or variable rate preferred stock, which is sometimes referred to as “auction rate” preferred stock. All shares of preferred stock that we may issue will be identical and of equal rank except as to the particular terms thereof that may be fixed by our Board, and all shares of each series of preferred stock will be identical and of equal rank except as to the dates from which cumulative distributions, if any, thereon will be cumulative. If we issue shares of preferred stock, holders of such preferred stock will be entitled to receive cash distributions at an annual rate that will be fixed or will vary for the successive dividend periods for each series. In general, the dividend periods for fixed rate preferred stock can range from quarterly to weekly and are subject to extension. We urge you to read the applicable prospectus supplement and any free writing prospectus that we may authorize to be provided to you related to any preferred stock being offered, as well as the complete articles supplementary that contain the terms of the applicable series of preferred stock.

DESCRIPTION OF SUBSCRIPTION RIGHTS THAT WE MAY ISSUE
We may issue subscription rights to purchase common stock. Subscription rights may be issued independently or together with any other offered security and may or may not be transferable by the person purchasing or receiving the subscription rights. In connection with any subscription rights offering to our stockholders, we may enter into a standby underwriting or other arrangement with one or more underwriters or other persons pursuant to which such underwriters or other persons would purchase any offered securities remaining unsubscribed for after such subscription rights offering. We will not offer transferable subscription rights to our stockholders at a price equivalent to less than the then current net asset value per share of common stock, excluding underwriting commissions, unless we first file a post-effective amendment that is declared effective by the SEC with respect to such issuance and the common stock to be purchased in connection with the rights represents no more than one-third of our outstanding common stock at the time such rights are issued. In connection with a subscription rights offering to our stockholders, we would distribute certificates evidencing the subscription rights and a prospectus supplement to our stockholders on the record date that we set for receiving subscription rights in such subscription rights offering. Our common stockholders will indirectly bear the expenses of such subscription rights offerings, regardless of whether our common stockholders exercise any subscription rights.
The applicable prospectus supplement would describe the following terms of subscription rights in respect of which this prospectus is being delivered:

the title of such subscription rights;

the exercise price or a formula for the determination of the exercise price for such subscription rights;

the number or a formula for the determination of the number of such subscription rights issued to each stockholder;

the extent to which such subscription rights are transferable;

if applicable, a discussion of the material U.S. federal income tax considerations applicable to the issuance or exercise of such subscription rights;

the date on which the right to exercise such subscription rights would commence, and the date on which such rights shall expire (subject to any extension);

the extent to which such subscription rights include an over-subscription privilege with respect to unsubscribed securities;

if applicable, the material terms of any standby underwriting or other purchase arrangement that we may enter into in connection with the subscription rights offering; and

any other terms of such subscription rights, including terms, procedures and limitations relating to the exchange and exercise of such subscription rights.
Exercise of subscription rights
Each subscription right would entitle the holder of the subscription right to purchase for cash such amount of shares of common stock at such exercise price as shall in each case be set forth in, or be determinable as set forth in, the prospectus supplement relating to the subscription rights offered thereby or another report filed with the SEC. Subscription rights may be exercised at any time up to the close of business on the expiration date for such subscription rights set forth in the applicable prospectus supplement. After the close of business on the expiration date, all unexercised subscription rights would become void.

TABLE OF CONTENTS
Subscription rights may be exercised as set forth in the prospectus supplement relating to the subscription rights offered thereby. Upon receipt of payment and the subscription rights certificate properly completed and duly executed at the corporate trust office of the subscription rights agent or any other office indicated in the prospectus supplement, we will forward, as soon as practicable, the shares of common stock purchasable upon such exercise. We may determine to offer any unsubscribed offered shares of common stock directly to stockholders, persons other than stockholders, to or through agents, underwriters or dealers or through a combination of such methods, including pursuant to standby underwriting or other arrangements, as set forth in the applicable prospectus supplement. We have not previously completed such an offering of subscription rights.

DESCRIPTION OF DEBT SECURITIES THAT WE MAY ISSUE
We may issue debt securities in one or more series in the future that, if publically offered, will be under an indenture to be entered into between the Company and a trustee. We urge you to read the applicable prospectus supplement and any free writing prospectus that we may authorize to be provided to you related to the series of debt securities being offered, as well as the complete indentures that contain the terms of the debt securities.
As required by federal law for all bonds and notes of companies that are publicly offered, debt securities are governed by a document called an “indenture.” An indenture is a contract between us and U.S. Bank National Association, a 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.” Second, the trustee performs certain administrative duties for us.
Because this section is a summary, it does not describe every aspect of the debt securities and the indenture. We urge you to read the indenture because it, and not this description, defines your rights as a holder of debt securities. For example, in this section, we use capitalized words to signify terms that are specifically defined in the indenture. Some of the definitions are repeated in this prospectus, but for the rest you will need to read the indenture. We have filed the form of the indenture with the SEC. See “Available Information” for information on how to obtain a copy of the indenture.
The prospectus supplement, which will accompany this prospectus, will describe the particular series of debt securities being offered, including among other things:

the designation or title of the series of debt securities;

the total principal amount of the series of debt securities;

the percentage of the principal amount at which the series of debt securities will be offered;

the date or dates on which principal will be payable;

the rate or rates (which may be either fixed or variable) and/or the method of determining such rate or rates of interest, if any;

the date or dates from which any interest will accrue, or the method of determining such date or dates, and the date or dates on which any interest will be payable;

the terms for redemption, extension or early repayment, if any;

the currencies in which the series of debt securities are issued and payable;

whether the amount of payments of principal, premium or interest, if any, on a series of debt securities will be determined with reference to an index, formula or other method (which could be based on one or more currencies, commodities, equity indices or other indices) and how these amounts will be determined;

the place or places of payment, transfer, conversion and/or exchange of the debt securities;

the denominations in which the offered debt securities will be issued;

the provision for any sinking fund;

any restrictive covenants;

whether the series of debt securities are issuable in certificated form;

any provisions for defeasance or covenant defeasance;

any special federal income tax implications, including, if applicable, U.S. federal income tax considerations relating to original issue discount;

whether and under what circumstances we will pay additional amounts in respect of any tax, assessment or governmental charge and, if so, whether we will have the option to redeem the debt securities rather than pay the additional amounts (and the terms of this option);

any provisions for convertibility or exchangeability of the debt securities into or for any other securities;
