6,000,000 Shares

Common Stock

We are offering for sale 6,000,000 shares of our common stock. Our common stock is traded on the NASDAQ Global Select Market under the symbol “PFLT.” The last reported closing sale price for our common stock on October 23, 2017 was $14.53 per share.

Our investment objectives are to generate current income and capital appreciation while seeking to preserve capital by investing primarily in loans bearing a variable-rate of interest, or Floating Rate Loans, and other investments made to U.S. middle-market companies. Floating Rate Loans or variable-rate investments pay interest at variable-rates, which are determined periodically, on the basis of a floating base lending rate such as the London Interbank Offered Rate, or LIBOR, with or without a floor plus a fixed spread. We can offer no assurances that we will achieve our investment objectives.

We are managed by PennantPark Investment Advisers, LLC. PennantPark Investment Administration, LLC provides the administrative services necessary for us to operate.

FEES AND EXPENSES

The following table will assist you in understanding the various 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 from actual results. The following table should not be considered a representation of our future expenses. Actual expenses may be greater or less than amounts shown below. Except where the context suggests otherwise, whenever this prospectus supplement and the accompanying prospectus contains a reference to fees or expenses paid by “you” or “us” or that “we” will pay, stockholders will indirectly bear such fees or expenses as investors in us.

S-8

Example

The following example illustrates the projected dollar amount of total cumulative expenses that you would pay on a $1,000 hypothetical investment in common shares, assuming (1) a     % sales load (underwriting discounts and commissions) (see note 1 above) and included offering expenses totaling     %, (2) total net estimated annual expenses of     % of average net assets attributable to common shares as set forth in the table above (other than performance-based incentive fees) and (3) a 5% annual return:

This example and the expenses in the table above should not be considered a representation of our future expenses. Actual expenses may be greater or less than those assumed. The table above is to assist you in understanding the various costs and expenses that an investor in our common stock will bear directly or indirectly. While the example assumes, as required by the SEC, a 5% annual return, our performance will vary and may result in a return greater or less than 5%. If we were to earn an annual return equal to or less than 5% from net investment income, the incentive fee under our Investment Management Agreement would not be earned or payable. If our returns on our investments, including the realized capital gains, result in an incentive fee, then our expenses would be higher. The example assumes that all distributions are reinvested at NAV. Reinvestment of distributions under our dividend reinvestment plan may occur at a price per share that differs from NAV. See “Distributions” and “Dividend Reinvestment Plan” in the accompanying prospectus for more information.

RISK FACTORS

Before you invest in our securities, you should be aware of various risks, including those described below and in the accompanying prospectus. You should carefully consider these risk factors, together with all of the other information included in this prospectus supplement and the accompanying prospectus before you decide whether to make an investment in our securities. The risks set out below are not the only risks we face. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition and/or operating results. If any of the following events occur, our business, financial condition and results of operations could be materially adversely affected. In such case, our net asset value and the trading price of our common stock may decline, and you may lose all or part of your investment.

There are material limitations with making preliminary estimates of our financial results for the period ended September 30, 2017 prior to the completion of our financial procedures for such period.

The preliminary financial estimates contained in “Supplemental Prospectus Summary—Recent Developments” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Recent Developments” are not a comprehensive statement of our financial results for the period ended September 30, 2017 and have not been audited by our independent registered public accounting firm. Our consolidated financial statements for the period ended September 30, 2017 will not be available until after this offering is completed and, consequently, will not be available to you prior to investing in this offering. Our actual financial results for the period ended September 30, 2017 may differ materially from the preliminary financial estimates we have provided as a result of the completion of our financial closing procedures, final adjustments and other developments arising between now and the time that our financial results for the period ended September 30, 2017 are finalized. The preliminary financial data included herein have been prepared by, and are the responsibility of management. Our independent registered public accounting firm has not audited, reviewed, compiled or performed any procedures with respect to such preliminary estimates. Accordingly, our independent registered public accounting firm does not express an opinion or any other form of assurance with respect thereto.

FORWARD-LOOKING STATEMENTS

This prospectus supplement contains statements that constitute forward-looking statements, which relate to us and our consolidated subsidiaries regarding future events or our future performance or future financial condition. These forward-looking statements are not historical facts, but rather are based on current expectations, estimates and projections about our Company, our industry, our beliefs and our assumptions. The forward-looking statements contained in this prospectus supplement involve risks and uncertainties, including statements as to:

We use words such as “anticipates,” “believes,” “expects,” “intends,” “seeks,” “plans,” “estimates” and similar expressions to identify forward-looking statements. You should not place undue influence on the forward-looking statements as our actual results could differ materially from those projected in the forward-looking statements for any reason, including the factors set forth in the accompanying prospectus under “Risk Factors” and elsewhere in this prospectus supplement and the accompanying prospectus.

Although we believe that the assumptions on which these forward-looking statements are based are reasonable, any of those assumptions could prove to be inaccurate, and as a result, the forward-looking statements based on those assumptions also could be inaccurate. Important assumptions include our ability to originate new loans and investments, certain margins and levels of profitability and the availability of additional capital. In light of these and other uncertainties, the inclusion of a projection or forward-looking statement in this prospectus supplement should not be regarded as a representation by us that our plans and objectives will be achieved.

We have based the forward-looking statements included in this prospectus supplement on information available to us on the date of this prospectus supplement, and we assume no obligation to update any such

S-11

forward-looking statements. Although we undertake no obligation to revise or update any forward-looking statements in this prospectus supplement, whether as a result of new information, future events or otherwise, you are advised to consult any additional disclosures that we may make directly to you or through reports that we in the future may file with the SEC, including reports on Form 10-K/Q and current reports on Form 8-K.

You should understand that under Section 27A(b)(2)(B) of the Securities Act of 1933, as amended, or the Securities Act, and Section 21E(b)(2)(B) of the Securities Exchange Act of 1934, as amended, or the Exchange Act, the “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995 do not apply to forward-looking statements made in connection with any offering of securities pursuant to this prospectus supplement or in periodic reports we file under the Exchange Act.

S-12

USE OF PROCEEDS

We estimate that net proceeds we will receive from the sale of 6,000,000 shares of our common stock in this offering will be approximately $         million (or approximately $         million if the underwriters fully exercise their option to purchase additional shares), after deducting the underwriting discounts and commissions of approximately $         million (or approximately $         million if the underwriters fully exercise their option to purchase additional shares) and estimated offering expenses of approximately $425,000 payable by us. The Investment Adviser has agreed to bear $         million of underwriting discounts and/or commissions in connection with this offering (or approximately $         million if the underwriters fully exercise their option to purchase additional shares), which will be determined at pricing. The amount of net proceeds may be more or less than the amount described in this prospectus supplement, which will be determined at pricing.

We expect to use the net proceeds from selling securities pursuant to this prospectus supplement to reduce outstanding obligations under our Credit Facility, to invest in new or existing portfolio companies, to capitalize a subsidiary or new joint venture or for other general corporate or strategic purposes. Affiliates of certain of the underwriters serve as lenders under our Credit Facility and thereby may receive proceeds from this offering that are used to reduce our outstanding obligations under our Credit Facility.

As of June 30, 2017, we had $83.8 million of unused borrowing capacity, subject to maintenance of the applicable total assets to debt ratio, as set forth in the 1940 Act, and $291.2 million in borrowings outstanding under our $375 million Credit Facility. Borrowings under our Credit Facility bear interest at an annual rate equal to LIBOR plus 200 basis points per annum during the revolving period, and the rate resets to LIBOR plus 425 points per annum for the remaining two years. At June 30, 2017, the interest rate on the Credit Facility was 3.00%, excluding the undrawn commitment fee of 0.375%. The Credit Facility is a revolving facility maturing in August 2020 and is secured by all of the assets of Funding I. Amounts repaid under our Credit Facility remain available for future borrowings during the revolving period. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in this prospectus supplement and the accompanying prospectus for more information.

We may invest the proceeds from an offering of securities in new or existing portfolio companies, and such investments may take up to a year from the closing of such offering, in part because privately negotiated investments in illiquid securities or private middle-market companies require substantial due diligence and structuring. During this period, we may use the net proceeds from our offering to reduce then-outstanding obligations under our Credit Facility or to invest such proceeds in cash equivalents, U.S. government securities and other high-quality debt investments that mature in one year or less. We expect to earn yields on such investments, if any, that are lower than the interest income that we anticipate receiving in respect of investments in non-temporary investments. As a result, any distributions we make during this investment period may be lower than the distributions that we would expect to pay when such proceeds are fully invested in non-temporary investments. See “Regulation—Temporary Investments” in the accompanying prospectus for more information.

S-13

CAPITALIZATION

The following table sets forth our cash and capitalization on June 30, 2017 (1) on an actual basis and (2) on an as-adjusted basis to reflect the effects of the sale of 6,000,000 shares of common stock in this offering at an offering price of $         per share ($         per share net of the sales load), and estimated offering expenses of $425,000 payable by us. The as-adjusted information is illustrative only; our capitalization following the completion of this offering is subject to further adjustments. You should read this table together with “Use of Proceeds” set forth in this prospectus supplement and in the accompanying prospectus for more information. You should also read this table with our Consolidated Financial Statements and related notes thereto, in conjunction with “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in this prospectus supplement and in the accompanying prospectus for more information.

PRICE RANGE OF COMMON STOCK

Our common stock is traded on the NASDAQ Global Select Market under the symbol “PFLT.” The following table lists the high and low closing sale price for our common stock, the closing sale prices as a premium or (discount) to our NAV per share and distributions per quarter per share since October 1, 2015. On October 23, 2017, the last reported closing sale price of our common stock was $14.53 per share.

Shares of BDCs may trade at a market price both above and below the NAV that is attributable to those shares. Our shares have traded above and below our NAV. Our shares closed on the NASDAQ Global Select Market at $14.11 and $13.23 on June 30, 2017 and September 30, 2016, respectively. Our NAV per share was $14.05 and $14.06 as of the same dates. 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 our NAV in the future.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Overview

PennantPark Floating Rate Capital Ltd. is a BDC whose objectives are to generate current income and capital appreciation while seeking to preserve capital by investing primarily in Floating Rate Loans and other investments made to U.S. middle-market companies.

We believe that Floating Rate Loans to U.S. middle-market companies offer attractive risk-reward to investors due to a limited amount of capital available for such companies and the potential for rising interest rates. We use the term “middle-market” to refer to companies with annual revenues between $50 million and $1 billion. Our investments are typically rated below investment grade. Securities rated below investment grade are often referred to as “leveraged loans” or “high yield” securities or “junk bonds” and are often higher risk compared to debt instruments that are rated above investment grade and have speculative characteristics. However, when compared to junk bonds and other non-investment grade debt, senior secured Floating Rate Loans typically have more robust capital-preserving qualities, such as historically lower default rates than junk bonds, represent the senior source of capital in a borrower’s capital structure and often have certain of the borrower’s assets pledged as collateral. Our debt investments may generally range in maturity from three to ten years and are made to U.S. and, to a limited extent, non-U.S. corporations, partnerships and other business entities which operate in various industries and geographical regions.

Under normal market conditions, we generally expect that at least 80% of the value of our Managed Assets will be invested in Floating Rate Loans and other investments bearing a variable-rate of interest. We generally expect that senior secured debt, or first lien loans, will represent at least 65% of our overall portfolio. We also generally expect to invest up to 35% of our overall portfolio opportunistically in other types of investments, including mezzanine debt and, to a lesser extent, equity investments. We seek to create a diversified portfolio by generally targeting an investment size between $3 million and $15 million, on average, although we expect that this investment size will vary proportionately with the size of our capital base.

Our investment activity depends on many factors, including the amount of debt and equity capital available to middle-market companies, the level of merger and acquisition activity for such companies, the general economic environment and the competitive environment for the types of investments we make. We have used, and expect to continue to use our Credit Facility, proceeds from the rotation of our portfolio and proceeds from public and private offerings of securities to finance our investment objectives.

Organization and Structure of PennantPark Floating Rate Capital Ltd.

PennantPark Floating Rate Capital Ltd., a Maryland corporation organized in October 2010, is a closed-end, externally managed, non-diversified investment company that has elected to be treated as a BDC under the 1940 Act. In addition, for federal income tax purposes we elected to be treated, and intend to qualify annually, as a RIC under the Code.

Our investment activities are managed by the Investment Adviser. Under our Investment Management Agreement, we have agreed to pay our Investment Adviser an annual base management fee based on our average adjusted gross total assets as well as an incentive fee based on our investment performance. We have also entered into an Administration Agreement with the Administrator. Under our Administration Agreement, we have agreed to reimburse the Administrator for our allocable portion of overhead and other expenses incurred by the Administrator in performing its obligations under our Administration Agreement, including rent and our allocable portion of the costs of compensation and related expenses of our Chief Compliance Officer, Chief Financial Officer and their respective staffs. Our board of directors, a majority of whom are independent of us, provides overall supervision of our activities, and the Investment Adviser supervises our day-to-day activities.

S-18

Revenues

We generate revenue in the form of interest income on the debt securities we hold and capital gains and dividends, if any, on investment securities that we may acquire in portfolio companies. Our debt investments, whether in the form of senior secured debt or mezzanine debt, typically have a term of three to ten years and bear interest at a fixed or floating rate. Interest on debt securities is generally payable quarterly or semiannually. In some cases, our investments provide for deferred interest payments or payment-in-kind, or PIK, interest. The principal amount of the debt securities and any accrued but unpaid interest generally becomes due at the maturity date. In addition, we may generate revenue in the form of amendment, commitment, origination, structuring or diligence fees, fees for providing managerial assistance and possibly consulting fees. Loan origination fees, original issue discount, or OID, and market discount or premium are capitalized and accreted or amortized using the effective interest method as interest income or, in the case of deferred financing costs, as interest expense. Dividend income, if any, is recognized on an accrual basis on the ex-dividend date to the extent that we expect to collect such amounts. From time to time, the Company receives certain fees from portfolio companies, which are non-recurring in nature. Such fees include loan prepayment penalties, structuring fees and loan waiver and amendment fees, and are recorded as other investment income when earned.

Expenses

Our primary operating expenses include the payment of a management fee and the payment of an incentive fee to our Investment Adviser, if any, our allocable portion of overhead under our Administration Agreement and other operating costs as detailed below. Our management fee compensates our Investment Adviser for its work in identifying, evaluating, negotiating, consummating and monitoring our investments. Additionally, we pay interest expense on the outstanding debt and unused commitment fees on undrawn amounts, under our Credit Facility. We bear all other direct or indirect costs and expenses of our operations and transactions, including:

S-19

Generally, during periods of asset growth, we expect our general and administrative expenses to be relatively stable or to decline as a percentage of total assets and increase during periods of asset declines. Incentive fees, interest expense and costs relating to future offerings of securities would be additive to the expenses described above.

PORTFOLIO AND INVESTMENT ACTIVITY

As of June 30, 2017, our portfolio totaled $698.9 million and consisted of $613.3 million of senior secured debt, $32.4 million of second lien secured debt, $32.5 million of subordinated debt and $20.7 million of preferred and common equity. Our debt portfolio consisted of 99% variable-rate investments (including 9% where LIBOR was below the floor) and 1% fixed-rate investments. As of June 30, 2017, we had one company on non-accrual, representing 0.4% and 0.2% of our overall portfolio on a cost and fair value basis, respectively.

Sales and repayments of investments for the three months ended June 30, 2016 totaled $40.3 million. For the nine months ended June 30, 2016, we invested $257.7 million in 29 new and 16 existing portfolio companies with a weighted average yield on debt investments of 8.1%. Sales and repayments of investments for the nine months ended June 30, 2016 totaled $97.1 million.

CRITICAL ACCOUNTING POLICIES

The preparation of our Consolidated Financial Statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amount of our assets and liabilities at the date of the Consolidated Financial Statements and the reported amounts of income and expenses during the reported periods. In the opinion of management, all adjustments, which are of a normal recurring nature, considered necessary for

S-20

the fair presentation of financial statements have been included. Actual results could differ from these estimates due to changes in the economic and regulatory environment, financial markets and any other parameters used in determining such estimates and assumptions. We may reclassify certain prior period amounts to conform to the current period presentation. We have eliminated all intercompany balances and transactions. References to the Accounting Standards Codification, or ASC, serve as a single source of accounting literature. Subsequent events are evaluated and disclosed as appropriate for events occurring through the date the Consolidated Financial Statements are issued. In addition to the discussion below, we describe our critical accounting policies in the notes to our Consolidated Financial Statements.

Investment Valuations

We expect that there may not be readily available market values for many of the investments which are or will be in our portfolio, and we value such investments at fair value as determined in good faith by or under the direction of our board of directors using a documented valuation policy and a consistently applied valuation process, as described in this prospectus supplement. With respect to investments for which there is no readily available market value, the factors that the board of directors may take into account in pricing our investments at fair value include, as relevant, the nature and realizable value of any collateral, the portfolio company’s ability to make payments and its earnings and discounted cash flow, the markets in which the portfolio company does business, comparison to publicly traded securities and other relevant factors. When an external event such as a purchase transaction, public offering or subsequent equity sale occurs, we consider the pricing indicated by the external event to corroborate or revise our valuation. Due to the inherent uncertainty of determining the fair value of investments that do not have a readily available market value, the price used in an actual transaction may be different than our valuation and the difference may be material.

Our portfolio generally consists of illiquid securities, including debt and equity investments. With respect to investments for which market quotations are not readily available, or for which market quotations are deemed not reflective of the fair value, our board of directors undertakes a multi-step valuation process each quarter, as described below:

Our board of directors generally uses market quotations to assess the value of our investments for which market quotations are readily available. We obtain these market values from independent pricing services or at the bid prices obtained from at least two brokers or dealers, if available, or otherwise from a principal market

S-21

maker or a primary market dealer. The Investment Adviser assesses the source and reliability of bids from brokers or dealers. If our board of directors has a bona fide reason to believe any such market quote does not reflect the fair value of an investment, it may independently value such investments by using the valuation procedure that it uses with respect to assets for which market quotations are not readily available.

Fair value, as defined under ASC 820, is the price that we would receive upon selling an investment or pay to transfer a liability in an orderly transaction to a market participant in the principal or most advantageous market for the investment or liability. ASC 820 emphasizes that valuation techniques maximize the use of observable market inputs and minimize the use of unobservable inputs. Inputs refer broadly to the assumptions that market participants would use in pricing an asset or liability, including assumptions about risk. Inputs may be observable or unobservable. Observable inputs reflect the assumptions market participants would use in pricing an asset or liability based on market data obtained from sources independent of us. Unobservable inputs reflect the assumptions market participants would use in pricing an asset or liability based on the best information available to us on the reporting date.

ASC 820 classifies the inputs used to measure these fair values into the following hierarchies:

A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. Generally, most of our investments and our Credit Facility are classified as Level 3. Due to the inherent uncertainty of determining the fair value of investments that do not have a readily available market value, the price used in an actual transaction may be different than our valuation and those differences may be material.

In addition to using the above inputs in cash equivalents, investments and our Credit Facility valuations, we employ the valuation policy approved by our board of directors that is consistent with ASC 820. Consistent with our valuation policy, we evaluate the source of inputs, including any markets in which our investments are trading, in determining fair value.

The carrying value of our consolidated financial liabilities approximates fair value. We adopted ASC 825-10, which provides companies with an option to report selected financial assets and liabilities at fair value, and made an irrevocable election to apply ASC 825-10 to our Credit Facility. We elected to use the fair value option for our Credit Facility to align the measurement attributes of both our assets and liabilities while mitigating volatility in earnings from using different measurement attributes. Due to that election and in accordance with GAAP, we had $0.1 million in expenses relating to amendment costs on the Credit Facility during both the three and nine months ended June 30, 2017, respectively. For the same periods in the prior year, we incurred expenses of zero and $0.9 million, respectively, relating to amendment fees on the Credit Facility. ASC 825-10 establishes presentation and disclosure requirements designed to facilitate comparisons between companies that choose different measurement attributes for similar types of assets and liabilities and to more easily understand the effect on earnings of a company’s choice to use fair value. ASC 825-10 also requires entities to display the fair value of the selected assets and liabilities on the face of the Consolidated Statements of Assets and Liabilities and changes in fair value of the Credit Facility are reported in our Consolidated Statements of Operations. We elected not to apply ASC 825-10 to any other financial assets or liabilities. For the three and nine months ended June 30, 2017, our Credit Facility had a net change in unrealized appreciation of $1.9 million

S-22

and $3.0 million, respectively. For the three and nine months ended June 30, 2016, our Credit Facility had a net change in unrealized depreciation of $0.3 million and $0.5 million, respectively. As of June 30, 2017 and September 30, 2016, the net unrealized (appreciation) depreciation on our Credit Facility totaled $(2.5) million and $0.5 million, respectively. We use a nationally recognized independent valuation service to measure the fair value of our Credit Facility in a manner consistent with the valuation process that the board of directors uses to value our investments.

Revenue Recognition

We record interest income on an accrual basis to the extent that we expect to collect such amounts. For loans and debt investments with contractual PIK interest, which represents interest accrued and added to the loan balance that generally becomes due at maturity, we will generally not accrue PIK interest when the portfolio company valuation indicates that such PIK interest is not collectible. We do not accrue as a receivable interest on loans and debt investments if we have reason to doubt our ability to collect such interest. Loan origination fees, OID, market discount or premium and deferred financing costs on liabilities, which we do not fair value, are capitalized and then accreted or amortized using the effective interest method as interest income or, in the case of deferred financing costs, as interest expense. Dividend income, if any, is recognized on an accrual basis on the ex-dividend date to the extent that we expect to collect such amounts. From time to time, the Company receives certain fees from portfolio companies, which are non-recurring in nature. Such fees include loan prepayment penalties, structuring fees and amendment fees, and are recorded as other investment income when earned.

Net Realized Gains or Losses and Net Change in Unrealized Appreciation or Depreciation

We measure realized gains or losses by the difference between the net proceeds from the repayment or sale and the amortized cost basis of the investment, using the specific identification method, without regard to unrealized appreciation or depreciation previously recognized, but considering unamortized upfront fees and prepayment penalties. Net change in unrealized appreciation or depreciation reflects the change in the fair values of our portfolio investments and Credit Facility during the reporting period, including any reversal of previously recorded unrealized appreciation or depreciation, when gains or losses are realized.

Foreign Currency Translation

Our books and records are maintained in U.S. dollars. Any foreign currency amounts are translated into U.S. dollars on the following basis:

1. Fair value of investment securities, other assets and liabilities – at the exchange rates prevailing at the end of the applicable period; and

2. Purchases and sales of investment securities, income and expenses – at the exchange rates prevailing on the respective dates of such transactions.

Although net assets and fair values are presented based on the applicable foreign exchange rates described above, we do not isolate that portion of the results of operations due to changes in foreign exchange rates on investments, other assets and debt from the fluctuations arising from changes in fair values of investments and liabilities held. Such fluctuations are included with the net realized and unrealized gain or loss from investments and liabilities.

Payment-in-Kind Interest or PIK

We have investments in our portfolio which contain a PIK interest provision. PIK interest is added to the principal balance of the investment and is recorded as income. In order for us to maintain our ability to be treated as a RIC for federal income tax purposes, substantially all of this income must be paid out to stockholders in the form of dividends for U.S. federal income tax purposes, even though we have not collected any cash with respect to interest on PIK securities.

S-23

Federal Income Taxes

We have elected to be treated, and intend to qualify annually to maintain our election to be treated, as a RIC under Subchapter M of the Code. To maintain our RIC tax election, we must, among other requirements, meet certain annual source-of-income and quarterly asset diversification requirements. We also must annually distribute dividends for U.S. federal income tax purposes to our stockholders out of the assets legally available for distribution of an amount generally at least equal to 90% of the sum of our net ordinary income and realized net short-term capital gains in excess of realized net long-term capital losses, or investment company taxable income, determined without regard to any deduction for dividends paid.

Although not required for us to maintain our RIC tax status, in order to preclude the imposition of a 4% nondeductible federal excise tax imposed on RICs, we must distribute dividends for U.S. federal income tax purposes to our stockholders in respect of each calendar year of an amount at least equal to the sum of (1) 98% of our net ordinary income (subject to certain deferrals and elections) for the calendar year, (2) 98.2% of the excess, if any, of our capital gains over our capital losses, or capital gain net income (adjusted for certain ordinary losses) for the one-year period ending on October 31 of the calendar year plus (3) the sum of any net ordinary income plus capital gain net income for preceding years that was not distributed during such years and on which we did not incur any federal income tax. In addition, although we may distribute realized net capital gains (i.e., net long-term capital gains in excess of net short-term capital losses), if any, at least annually, out of the assets legally available for such distributions in the manner described above, we have retained and may continue to retain such net capital gains or investment company taxable income, contingent on maintaining our ability to be subject to tax as a RIC, in order to provide us with additional liquidity.

Because federal income tax regulations differ from GAAP, distributions in accordance with tax regulations may differ from net investment income and net realized gain recognized for financial reporting purposes. Differences between tax regulations and GAAP may be permanent or temporary. Permanent differences are reclassified among capital accounts in the Consolidated Financial Statements to reflect their appropriate tax character. Temporary differences arise when certain items of income, expense, gain or loss are recognized at some time in the future.

We have formed and expect to continue to form certain taxable subsidiaries, including the Taxable Subsidiary, which are subject to tax as corporations. The Taxable Subsidiary allows us to hold equity securities of certain portfolio companies treated as pass-through entities for U.S. federal income tax purposes while allowing us to maintain our ability to qualify as a RIC under the Code.

RESULTS OF OPERATIONS

Set forth below are the results of operations for the three and nine months ended June 30, 2017 and 2016.

Investment Income

Investment income for the three and nine months ended June 30, 2017 was $15.2 million and $41.0 million, respectively, and was attributable to $13.9 million and $37.1 million from senior secured loans and $1.3 million and $3.9 million from second lien secured debt and subordinated debt. This compares to investment income for the three and nine months ended June 30, 2016, which was $10.8 million and $30.9 million, respectively, and was attributable to $9.0 million and $26.0 million from senior secured loans and the remainder from second lien secured debt and subordinated debt. The increase in investment income compared to the same periods in the prior year was primarily due to the growth of our portfolio.

Expenses

Expenses for the three and nine months ended June 30, 2017 totaled $7.0 million and $18.0 million, respectively. Base management fee for the same periods totaled $1.8 million and $5.1 million, incentive fee

S-24

totaled $1.4 million (including $0.2 million on realized gains and $0.4 million on unrealized gains accrued but not payable) and $3.4 million (including $0.2 million on realized gains and $0.9 million on unrealized gains accrued but not payable), Credit Facility expenses totaled $2.5 million and $6.3 million, general and administrative expenses totaled $1.2 million and $3.0 million and provision for taxes totaled $0.1 million and $0.2 million, respectively. This compares to expenses for the three and nine months ended June 30, 2016, which totaled $4.0 million and $11.7 million, respectively. Base management fee for the same periods totaled $1.3 million and $3.6 million, incentive fee totaled $0.5 million and $1.3 million, Credit Facility expenses totaled $1.3 million and $4.2 million (including $0.9 million of amendment expenses) and general and administrative expenses totaled $0.9 million and $2.6 million, respectively. The increase in expenses compared with the same periods in the prior year was primarily due to increases in base management and incentive fees as a result from the growth of our portfolio.

Net Investment Income

Net investment income totaled $8.2 million and $23.0 million, or $0.25 and $0.78 per share, for the three and nine months ended June 30, 2017, respectively. Net investment income totaled $6.8 million and $19.2 million, or $0.26 and $0.72 per share, for the three and nine months ended June 30, 2016, respectively. The increase in net investment income compared to the same period in the prior year was primarily due to the growth of our portfolio.

Net Realized Gains or Losses

Sales and repayments of investments for the three and nine months ended June 30, 2017 totaled $172.9 million and $314.8 million and net realized gains totaled $2.5 million and $5.0 million, respectively. Sales and repayments of investments totaled $40.3 million and $97.1 million and realized gains (losses) totaled $0.2 million and $(2.0) million for the three and nine months ended June 30, 2016, respectively. The change in realized gains/losses was primarily due to changes in the market conditions of our investments and the values at which they were realized.

Unrealized Appreciation or Depreciation on Investments and Credit Facility

For the three and nine months ended June 30, 2017, we reported a net change in unrealized appreciation on investments of $0.6 million and $0.4 million, respectively. For the three and nine months ended June 30, 2016, we reported a net change in unrealized appreciation (depreciation) on investments of $6.1 million and $(0.1) million, respectively. As of June 30, 2017 and September 30, 2016, our net unrealized appreciation on investments totaled $1.4 million and $1.0 million, respectively. The net change in unrealized appreciation on our investments was driven primarily by changes in capital market conditions, the financial performance of certain portfolio companies and the reversal of unrealized depreciation (appreciation) on investments that were sold.

For the three and nine months ended June 30, 2017, our Credit Facility had a net change in unrealized appreciation of $1.9 million and $3.0 million, respectively. For the three and nine months ended June 30, 2016, our Credit Facility had a net change in unrealized depreciation of $0.3 million and $0.5 million, respectively. As of June 30, 2017 and September 30, 2016, net unrealized (appreciation) depreciation on our Credit Facility totaled $(2.5) million and $0.5 million, respectively. The change in net unrealized depreciation compared to the same periods in the prior year was primarily due to changes in the capital markets.

Net Change in Net Assets Resulting from Operations

Net change in net assets resulting from operations totaled $9.3 million and $25.5 million, or $0.29 and $0.86 per share, respectively, for the three and nine months ended June 30, 2017. This compares to a net change in net assets resulting from operations which totaled $13.4 million and $17.6 million, or $0.50 and $0.66 per share, respectively, for the three and nine months ended June 30, 2016. The decrease/increase in the change in net assets from operations compared to the same periods in the prior year was primarily due to changes in portfolio investment values during the reporting periods.

S-25

LIQUIDITY AND CAPITAL RESOURCES

Our liquidity and capital resources are derived from public offerings, our Credit Facility, cash flows from operations, including investment sales and repayments, and income earned. Our primary use of funds from operations includes investments in portfolio companies and payments of fees and other operating expenses we incur. We have used, and expect to continue to use, our Credit Facility, the rotation of our portfolio and proceeds from public and private offerings of securities to finance our investment objectives.

Funding I’s multi-currency Credit Facility with the Lenders was $375.0 million as of June 30, 2017, subject to satisfaction of certain conditions and regulatory restrictions that the 1940 Act imposes on us as a BDC, has an interest rate spread above LIBOR of 200 basis points, a maturity date of August 2020 and a revolving period that ends in August 2018. As of June 30, 2017 and September 30, 2016, Funding I had $291.2 million and $232.9 million of outstanding borrowings under the Credit Facility, respectively. The Credit Facility had an interest rate of 3.00% and 2.57%, as of June 30, 2017 and September 30, 2016, respectively, excluding the undrawn commitment fees of 0.375%. The annualized weighted average cost of debt for the nine months ended June 30, 2017 and 2016, inclusive of the fee on the undrawn commitment and amendment costs on the Credit Facility, was 3.02% and 5.01%, respectively. As of June 30, 2017 and September 30, 2016, we had $83.8 million and $117.1 million of unused borrowing capacity under our Credit Facility, respectively, subject to the regulatory restrictions.

During the revolving period, the Credit Facility bears interest at LIBOR plus 200 basis points and, after the revolving period, the rate sets to LIBOR plus 425 basis points for the remaining two years, maturing in August 2020. The Credit Facility is secured by all of the assets of Funding I. Both PennantPark Floating Rate Capital Ltd. and Funding I have made customary representations and warranties and are required to comply with various covenants, reporting requirements and other customary requirements for similar credit facilities.

The Credit Facility contains covenants, including but not limited to, restrictions of loan size, currency types and amounts, industry requirements, average life of loans, geographic and individual portfolio concentrations, minimum portfolio yield and loan payment frequency. Additionally, the Credit Facility requires the maintenance of a minimum equity investment in Funding I and income ratio as well as restrictions on certain payments and issuance of debt. For instance, we must maintain at least $25 million in equity and must maintain an interest coverage ratio of at least 125%. The Credit Facility compliance reporting is prepared on a basis of accounting other than GAAP. As of June 30, 2017, we were in compliance with the covenants relating to our Credit Facility.

We own 100% of the equity interest in Funding I and treat the indebtedness of Funding I as our leverage. In accordance with the 1940 Act, with certain limited exceptions, we are only allowed to borrow amounts such that we are in compliance with our asset coverage ratio after such borrowing. Our Investment Adviser serves as collateral manager to Funding I under the Credit Facility.

Our interest in Funding I (other than the management fee) is subordinate in priority of payment to every other obligation of Funding I and is subject to certain payment restrictions set forth in the Credit Facility. We may receive cash distributions on our equity interests in Funding I only after it has made (1) all required cash interest and, if applicable, principal payments to the Lenders, (2) required administrative expenses and (3) claims of other unsecured creditors of Funding I. We cannot assure you that there will be sufficient funds available to make any distributions to us or that such distributions will meet our expectations from Funding I. The Investment Adviser has irrevocably directed that the management fee owed with respect to such services is to be paid to the Company so long as the Investment Adviser remains the collateral manager.

We may raise equity or debt capital through both registered offerings and private offerings of securities, securitizing a portion of our investments among other considerations or mergers and acquisitions. Furthermore, our Credit Facility availability depends on various covenants and restrictions as discussed in the preceding paragraphs. The primary use of existing funds and any funds raised in the future is expected to be for repayment

S-26

of indebtedness, investments in portfolio companies, cash distributions to our stockholders or for other general corporate purposes. In February 2017, we completed a follow-on public offering of 5,750,000 shares of common stock, which resulted in proceeds to us of $14.08 per share, including the exercise of the underwriters’ option to purchase additional shares, for gross proceeds of $81.0 million and net proceeds of $80.5 million after offering expenses. Our Investment Adviser paid $5.0 million in connection with this offering, which included the sales load and an additional supplemental payment.

At June 30, 2017 and September 30, 2016, we had cash equivalents of $49.0 million and $28.9 million, respectively, available for investing and general corporate purposes. We believe our liquidity and capital resources are sufficient to take advantage of market opportunities.

Our operating activities used cash of $93.9 million for the nine months ended June 30, 2017, and our financing activities provided cash of $113.8 million for the same period. Our operating activities used cash primarily for our investment activities and our financing activities provided cash primarily from our recent equity offering and net borrowings under the Credit Facility.

Our operating activities used cash of $143.2 million for the nine months ended June 30, 2016, and our financing activities provided cash of $138.5 million for the same period. Our operating activities used cash primarily for our investment activities and our financing activities provided cash primarily from net borrowings under the Credit Facility.

PennantPark Senior Secured Loan Fund I LLC

In May 2017, we and Trinity, a subsidiary of Kemper, formed PSSL, an unconsolidated joint venture. PSSL invests primarily in middle-market and other corporate debt securities consistent with our strategy. PSSL was formed as a Delaware limited liability company. As of June 30, 2017, PSSL had total assets of $77.8 million. PSSL’s portfolio consisted of debt investments in 14 portfolio companies as of June 30, 2017. As of June 30, 2017, at fair value, the largest investment in a single portfolio company in PSSL was $6.1 million and the five largest investments totaled $29.8 million. PSSL invests in portfolio companies in the same industries in which we may directly invest.

We provide capital to PSSL in the form of subordinated notes and equity interests. The subordinated notes are junior in right of payment to the repayment of temporary contributions made by us to fund investments of PSSL. As of June 30, 2017, we and Kemper owned 87.5% and 12.5%, respectively, of each of the outstanding subordinated notes and equity interests. Our investment in PSSL consisted of equity interests of $10.8 million and subordinated notes of $25.2 million as of June 30, 2017. As of the same date, we had commitments to fund subordinated notes to PSSL of $61.3 million, of which $36.1 million was unfunded. As of June 30, 2017, we had commitments to fund equity interests in PSSL of $26.2 million, of which $15.4 million was unfunded.

We and Kemper each appointed two members to PSSL’s four person board of directors and investment committee. All material decisions with respect to PSSL, including those involving its investment portfolio, require unanimous approval of a quorum of the board of directors or investment committee. Quorum is defined as (i) the presence of two members of the board of directors or investment committee; provided that at least one individual is present that was elected, designated or appointed by each member; (ii) the presence of three members of the board of directors or investment committee, provided that the individual that was elected, designated or appointed by the member with only one individual present shall be entitled to cast two votes on each matter; and (iii) the presence of four members of the board of directors or investment committee shall constitute a quorum, provided that two individuals are present that were elected, designated or appointed by each member.

Additionally, PSSL has entered into a senior secured revolving credit facility, or the PSSL Credit Facility, with Capital One, N.A. through its wholly-owned subsidiary, PennantPark Senior Secured Loan Facility LLC, or PSSL Subsidiary, which as of June 30, 2017 allowed PSSL Subsidiary to borrow up to $100.0 million at any one time outstanding, subject to leverage and borrowing base restrictions.

Contractual Obligations

A summary of our significant contractual payment obligations at cost as of June 30, 2017, including borrowings under our Credit Facility and other contractual obligations, is as follows:

We have entered into certain contracts under which we have material future commitments. Under our Investment Management Agreement, which was reapproved by our board of directors, including a majority of our directors who are not interested persons of us or the Investment Adviser, in February 2017, PennantPark Investment Advisers serves as our Investment Adviser. Payments under our Investment Management Agreement in each reporting period are equal to (1) a management fee equal to a percentage of the value of our gross assets and (2) an incentive fee based on our performance.

Under our Administration Agreement, which was reapproved by our board of directors, including a majority of our directors who are not interested persons of us, in February 2017, the Administrator furnishes us with office facilities and administrative services necessary to conduct our day-to-day operations. If requested to provide managerial assistance to our portfolio companies, we or the Administrator will be paid an additional amount based on the services provided. Payment under our Administration Agreement is based upon our allocable portion of the Administrator’s overhead in performing its obligations under our Administration Agreement, including rent and our allocable portion of the costs of our Chief Compliance Officer, Chief Financial Officer and their respective staffs.

If any of our contractual obligations discussed above are terminated, our costs under new agreements that we enter into may increase. In addition, we will likely incur significant time and expense in locating alternative parties to provide the services we expect to receive under our Investment Management Agreement and our Administration Agreement. Any new investment management agreement would also be subject to approval by our stockholders.

Recent Developments

On October 3, 2017, we declared a distribution of $0.095 per share payable on November 1, 2017 to stockholders of record as of October 19, 2017. Investors in this offering will not be entitled to this distribution.

Set forth below are certain preliminary estimates of our financial condition for the quarter ended September 30, 2017. These estimates are subject to the completion of our financial closing procedures and are not a comprehensive statement of our financial results for the year ended September 30, 2017. We advise you that our actual results may differ materially from these estimates as a result of the completion of our financial closing procedures, final adjustments and other developments arising between now and the time that our financial results for the year ended September 30, 2017 are finalized.

Net investment income is estimated to have totaled between $0.30 and $0.33 per share for the quarter ended September 30, 2017. This includes amounts received in a litigation settlement related to a former portfolio company of MCG of $0.07 per share net of the incentive fee payable on such amounts.

S-30

Net asset value as of September 30, 2017 is estimated to be between $14.08 and $14.11 per share.

As of September 30, 2017, we had borrowed $253.8 million under our $375 million Credit Facility.

Our and PSSL’s total investments at fair value are estimated to have increased by approximately $12 million and $29 million, respectively, during the three months ended September 30, 2017, after giving effect to purchases, sales, repayments and net change in unrealized appreciation.

The preliminary financial data included herein have been prepared by, and is the responsibility of, management. Our independent registered public accounting firm has not audited, reviewed, compiled or performed any procedures with respect to the accompanying preliminary financial data. Accordingly, our independent registered public accounting firm does not express an opinion or any other form of assurance with respect thereto.

Based on our historic activity levels and current pipeline, we anticipate an active fourth calendar quarter of origination activity.

In the near term, the Company intends to organize a series of debt investor meetings outside of the United States. A debt transaction may follow, subject to market conditions. We cannot assure you as to when a transaction will occur, if at all.

Off-Balance Sheet Arrangements

We currently engage in no off-balance sheet arrangements other than our funding requirements for the unfunded investments described above.

Distributions

In order to be treated as a RIC for federal income tax purposes and to not be subject to corporate-level tax on undistributed income or gains, we are required, under Subchapter M of the Code, to annually distribute dividends for U.S. federal income tax purposes to our stockholders out of the assets legally available for distribution of an amount generally at least equal to 90% of our investment company taxable income, determined without regard to any deduction for dividends paid.

Although not required for us to maintain our RIC tax status, in order to preclude the imposition of a 4% nondeductible federal excise tax imposed on RICs, we must distribute dividends for U.S. federal income tax purposes to our stockholders in respect of each calendar year of an amount at least equal to the sum of (1) 98% of our net ordinary income (subject to certain deferrals and elections) for the calendar year, (2) 98.2% of the excess, if any, of our capital gains over our capital losses, or capital gain net income (adjusted for certain ordinary losses) for the one-year period ending on October 31 of the calendar year plus (3) the sum of any net ordinary income plus capital gain net income for preceding years that was not distributed during such years and on which we did not incur any federal income tax. In addition, although we may distribute realized net capital gains (i.e., net long-term capital gains in excess of net short-term capital losses), if any, at least annually, out of the assets legally available for such distributions in the manner described above, we have retained and may continue to retain such net capital gains or investment company taxable income, contingent on maintaining our ability to be subject to tax as a RIC, in order to provide us with additional liquidity.

During the three and nine months ended June 30, 2017, we declared distributions of $0.285 and $0.855 per share, respectively, for total distributions of $9.3 million and $25.6 million, respectively. For the same periods in the prior year, we declared distributions of $0.285 and $0.855 per share, respectively, for total distributions of $7.6 million and $22.9 million, respectively. 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, common stockholders will be notified of the portion of those distributions deemed to be a tax return of capital. Tax characteristics of all distributions will be reported to stockholders subject to information reporting on Form 1099-DIV after the end of the calendar year and in our periodic reports filed with the SEC.

S-31

We intend to continue to make monthly distributions to our stockholders. Our monthly distributions, if any, are determined by the board of directors quarterly.

We maintain an “opt out” dividend reinvestment plan for our common stockholders. As a result, if we declare a distribution, then stockholders’ cash distributions will be automatically reinvested in additional shares of our common stock, unless they specifically “opt out” of the dividend reinvestment plan so as to receive cash distributions.

We may not be able to achieve operating results that will allow us to make distributions at a specific level or to increase the amount of these distributions from time to time. In addition, we may be limited in our ability to make distributions due to the asset coverage ratio for borrowings applicable to us as a BDC under the 1940 Act and/or due to provisions in future credit facilities. If we do not distribute a certain percentage of our income annually, we will suffer adverse tax consequences, including possible loss of our ability to be subject to tax as a RIC. We cannot assure stockholders that they will receive any distributions at a particular level.

Quantitative And Qualitative Disclosures About Market Risk

We are subject to financial market risks, including changes in interest rates. As of June 30, 2017, our debt portfolio consisted of 99% variable-rate investments (including 9% where LIBOR was below the floor) and 1% fixed-rate investments. The variable-rate loans are usually based on a LIBOR rate and typically have durations of three months, after which they reset to current market interest rates. Variable-rate investments subject to a floor generally reset by reference to the current market index after one to nine months only if the index exceeds the floor. In regards to variable-rate instruments with a floor, we do not benefit from increases in interest rates until such rates exceed the floor and thereafter benefit from market rates above any such floor. In contrast, our cost of funds, to the extent it is not fixed, will fluctuate with changes in interest rates since it has no floor.

Assuming that the most recent Consolidated Statements of Assets and Liabilities was to remain constant, and no actions were taken to alter the existing interest rate sensitivity, the following table shows the annualized impact of hypothetical base rate changes in interest rates:

Although management believes that this measure is indicative of our sensitivity to interest rate changes, it does not adjust for potential changes in the credit market, credit quality, size and composition of the assets on the Consolidated Statements of Assets and Liabilities and other business developments that could affect net increase in net assets resulting from operations or net investment income. Accordingly, no assurances can be given that actual results would not differ materially from those shown above.

Because we borrow money to make investments, our net investment income is dependent upon the difference between the rate at which we borrow funds and the rate at which we invest these funds, as well as our level of leverage. As a result, there can be no assurance that a significant change in market interest rates will not have a material adverse effect on our net investment income or net assets.

We may hedge against interest rate and foreign currency fluctuations by using standard hedging instruments such as futures, options and forward contracts or our Credit Facility subject to the requirements of the 1940 Act and applicable commodities laws. While hedging activities may insulate us against adverse changes in interest rates and foreign currencies, they may also limit our ability to participate in benefits of lower interest rates or higher exchange rates with respect to our portfolio of investments with fixed interest rates. During the periods covered by this prospectus supplement, we did not engage in interest rate hedging activities.

UNDERWRITING

We intend to offer the shares through the underwriters named in the table below. Morgan Stanley & Co. LLC, Goldman Sachs & Co. LLC, J.P. Morgan Securities LLC, Keefe, Bruyette & Woods, Inc., RBC Capital Markets, LLC and SunTrust Robinson Humphrey, Inc. are acting as joint bookrunners and representatives of the several underwriters. Subject to the terms and conditions described in an underwriting agreement among us and the underwriters, we have agreed to sell to the underwriters, and each underwriter has severally agreed to purchase from us, the number of shares set forth opposite the underwriter’s name.

The underwriting agreement provides that the obligations of the underwriters to purchase the shares included in this offering are subject to certain conditions precedent, including the absence of any material adverse change in our business and the receipt of certain certificates, opinions and letters from us, our counsel and our independent registered public accounting firm. The underwriters are committed to purchase all shares included in this offering, other than those shares covered by the option to purchase additional shares described below, if they purchase any of the shares. The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.

We have agreed to indemnify the several underwriters against certain liabilities, including liabilities under the Securities Act, or to contribute to payments the underwriters may be required to make in respect of those liabilities.

Commissions and Discounts

The underwriters have advised us that they propose initially to offer the shares to the public at the public offering price on the cover page of this prospectus supplement and to certain other Financial Industry Regulatory Authority (FINRA) members at that price less a concession not in excess of $         per share. After the public offering, the public offering price, concession and discount may be changed. No such change shall change the amount of proceeds to be received by us as set forth on the cover page of this prospectus supplement.

The following table shows the per share and total underwriting discounts and commissions we will pay to the underwriters assuming both no exercise and full exercise of the underwriters’ option to purchase up to an additional 900,000 shares.

S-33

Option to Purchase Additional Shares

We have granted an option to the underwriters to purchase up to 900,000 additional shares at the public offering price less the underwriting discount. The underwriters may exercise this option for 30 days from the date of this prospectus supplement. If the underwriters exercise this option, each will be obligated, subject to conditions contained in the underwriting agreement, to purchase the additional shares approximately proportionate to that underwriter’s initial purchase commitment.

No Sales of Similar Securities

We have agreed, with exceptions, not to sell or transfer any shares for 90 days after the date of this prospectus supplement without first obtaining the written consent of Morgan Stanley & Co. LLC.

Our executive officers and directors, PennantPark Investment Advisers, and Pennant Park Investment Administration have agreed, with exceptions, not to sell or transfer any common stock for 90 days after the date of this prospectus supplement without first obtaining the written consent of Morgan Stanley & Co. LLC. Specifically, we and these other individuals and entities have agreed not to directly or indirectly:

This lockup provision applies to common stock and to securities convertible into or exchangeable or exercisable for or repayable with common stock. It also applies to common stock owned now or acquired later by the person executing the agreement or for which the person executing the agreement later acquires the power of disposition.

Quotation on the NASDAQ Global Select Market

Our common stock is quoted on the NASDAQ Global Select Market under the symbol “PFLT.”

Price Stabilization and Short Positions

Until the distribution of the shares is completed, SEC rules may limit the underwriters from bidding for and purchasing our common stock. However, the underwriters may engage in transactions that stabilize the price of the common stock, such as bids or purchases to peg, fix or maintain that price.

S-34

If the underwriters create a short position in the common stock in connection with the offering (i.e., if they sell more shares than are listed on the cover of this prospectus supplement), the underwriters may reduce that short position by purchasing shares in the open market. The underwriters may also elect to reduce any short position by exercising all or part of the option to purchase additional shares as described above. In making this determination, the underwriters will consider, among other things, the price of shares available for purchase in the open market compared to the price at which the underwriters may purchase shares through the option to purchase additional shares. Purchases of the common stock to stabilize its price or to reduce a short position may cause the price of the common stock to be higher than it might be in the absence of such purchases.

The underwriters may also impose a penalty bid. This occurs when a particular underwriter repays to the underwriters a portion of the underwriting discount received by it because the representatives have repurchased shares sold by or for the account of such underwriter in stabilizing or short covering transactions.

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

The underwriters may make prospectuses available in electronic (PDF) format. A prospectus in electronic (PDF) format may be made available on a web site maintained by the underwriters, and the underwriters may distribute such prospectuses electronically.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders

PennantPark Floating Rate Capital Ltd. and its Subsidiaries

We have reviewed the accompanying consolidated statements of assets and liabilities of PennantPark Floating Rate Capital Ltd. and its Subsidiaries (collectively referred to as the “Company”), including the consolidated schedule of investments as of June 30, 2017, the related consolidated statements of operations for the three and nine months ended June 30, 2017 and 2016, and the related consolidated statements of changes in net assets and cash flows for the nine month periods ended June 30, 2017 and 2016. These consolidated financial statements are the responsibility of the Company’s management.

We conducted our review in accordance with the standards of the Public Company Accounting Oversight Board (United States). A review of interim financial information consists principally of applying analytical procedures to financial data and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the Public Company Accounting Oversight Board, the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

Based on our reviews, we are not aware of any material modifications that should be made to the accompanying consolidated financial statements referred to above for them to be in conformity with U.S. generally accepted accounting principles.

We have previously audited, in accordance with the standards of the Public Company Accounting Oversight Board, the consolidated statement of assets and liabilities of the Company, including the consolidated schedule of investments, as of September 30, 2016, and the related consolidated statements of operations, changes in net assets, and cash flows for the year then ended (not presented herein); and in our report dated November 22, 2016, we expressed an unqualified opinion on those consolidated financial statements. In our opinion, the information set forth in the accompanying consolidated statements of assets and liabilities as of September 30, 2016, is fairly stated, in all material respects, in relation to the consolidated statement of assets and liabilities from which it has been derived.
