7.75% Senior Notes due 2040



                 We are offering $200,000,000 in aggregate principal amount of 7.75% senior notes due 2040, which we refer to as the Notes. The Notes will mature on October 15, 2040. We will pay interest on the Notes on January 15, April 15, July 15, and October 15 of each year, beginning January 15, 2011. We may redeem the Notes in whole or in part at any time or from time to time on or after October 15, 2015, at the redemption price discussed under the caption "Specific Terms of the Notes and the Offering—Optional redemption" in this prospectus supplement. The Notes will be issued in minimum denominations of $25 and integral multiples of $25 in excess thereof.

                 The Notes will be our direct senior unsecured obligations and rank pari passu with all outstanding and future unsecured unsubordinated indebtedness issued by Ares Capital Corporation.

                 We intend to list the Notes on The New York Stock Exchange and we expect trading in the Notes on The New York Stock Exchange to begin within 30 days of the original issue date. The Notes are expected to trade "flat." This means that purchasers will not pay, and sellers will not receive, any accrued and unpaid interest on the Notes that is not included in the trading price. Currently, there is no public market for the Notes.

                 Ares Capital Corporation is a specialty finance company that is a closed-end, non-diversified management investment company incorporated in Maryland. We have elected to be regulated as a business development company under the Investment Company Act of 1940. Our investment objective is to generate both current income and capital appreciation through debt and equity investments. We invest primarily in first and second lien senior loans and mezzanine debt, which in some cases includes an equity component. To a lesser extent, we also make equity investments.

                 We are externally managed by Ares Capital Management LLC, an affiliate of Ares Management LLC, a global alternative asset manager and SEC registered investment adviser that as of June 30, 2010 managed investment funds with approximately $37 billion of committed capital. Ares Operations LLC, an affiliate of Ares Management LLC, provides the administrative services necessary for us to operate.

                 Investing in the Notes involves risks that are described in the "Risk Factors" sections beginning on page S-11 of this prospectus supplement and page 25 of the accompanying prospectus.

S-2


Table of Contents

 

You may be prevented from exchanging or transferring the Notes when they are subject to redemption. In case any Notes are to be redeemed in part only, the redemption notice will provide that, upon surrender of such Note, you will receive, without a charge, a new Note or Notes of authorized denominations representing the principal amount of your remaining unredeemed Notes.

 

Any exercise of our option to redeem the Notes will be done in compliance with the Investment Company Act of 1940, as amended, and the rules, regulations and interpretations promulgated thereunder (collectively, the "Investment Company Act"), to the extent applicable.

 

If we redeem only some of the Notes, the Trustee will determine the method for selection of the particular Notes to be redeemed, in accordance with the Investment Company Act and the rules and regulations promulgated thereunder, to the extent applicable. Unless we default in payment of the redemption price, on and after the date of redemption, interest will cease to accrue on the Notes called for redemption.

Repayment at option of Holders

 

Holders will not have the option to have the Notes repaid prior to the stated maturity date.

Covenant defeasance

 

The Notes are subject to covenant defeasance by us.

Form of Notes

 

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

Other covenants

 

In addition to the covenants described in the prospectus attached to this prospectus supplement, the following covenants shall apply to the Notes:

 

•       We agree that for the period of time during which the Notes are outstanding, we will not violate Section 18(a)(1)(A) as modified by Section 61(a)(1) of the Investment Company Act or any successor provisions.

S-3


Table of Contents

 

•       If, at any time, we are not subject to the reporting requirements of Sections 13 or 15(d) of the Securities Exchange Act to file any periodic reports with the SEC, we agree to furnish to holders of the Notes and the Trustee, for the period of time during which the Notes are outstanding, our audited annual consolidated financial statements, within 90 days of our fiscal year end, and unaudited interim consolidated financial statements, within 45 days of our fiscal quarter end. All such financial statements will be prepared, in all material respects, in accordance with applicable United States generally accepted accounting principles.

Modifications to events of default

 

The following event of default, as described in the prospectus attached to this prospectus supplement:

 

•       We do not pay the principal of, or any premium on, a debt security of the series on its due date, and do not cure this default within 5 days.

 

with respect to the Notes has been revised to read as follows:

 

•       We do not pay the principal of, or any premium on, any Note on its due date.

Global Clearance and Settlement Procedures

 

Interests in the Notes will trade in DTC's Same Day Funds Settlement System, and any permitted secondary market trading activity in such Notes will, therefore, be required by DTC to be settled in immediately available funds. None of the issuer, the Trustee or the paying agent will have any responsibility for the performance by DTC or its participants or indirect participants of their respective obligations under the rules and procedures governing their operations.

THE COMPANY

              This summary highlights some of the information contained elsewhere 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. You should read carefully the more detailed information set forth under "Risk Factors" in this prospectus supplement and in the accompanying prospectus and the other information included in this prospectus supplement and the accompanying prospectus. Except where the context suggests otherwise, the terms "we," "us," "our," "the Company" and "Ares Capital" refer to Ares Capital Corporation and its consolidated subsidiaries; "Ares Capital Management" or "the investment adviser" refers to Ares Capital Management LLC; "Ares Operations" refers to Ares Operations LLC; and "Ares" refers to Ares Partners Management Company LLC ("APMC") and its affiliated companies (other than portfolio companies of its affiliated funds), including Ares Management LLC, which we refer to separately as Ares Management.

              As described in more detail below, we consummated the acquisition (the "Allied Acquisition") of Allied Capital Corporation ("Allied Capital") on April 1, 2010. Other than as set forth in the pro forma financial information or otherwise specifically set forth herein or the accompanying prospectus, financial information presented herein and in the accompanying prospectus for and as of periods ended on or prior to March 31, 2010 does not include any information in respect of Allied Capital. In addition, other than as set forth in the pro forma financial information or otherwise specifically set forth herein or the accompanying prospectus, financial information for the six months ended June 30, 2010, including, without limitation, with respect to the Company's consolidated statements of operations, stockholders' equity and cash flows, only includes results attributable to Allied Capital for the period beginning on April 1, 2010.

Ares Capital

              Ares Capital, a Maryland corporation, is a specialty finance company that is a closed-end, non-diversified management investment company. We have elected to be regulated as a business development company, or a "BDC," under the Investment Company Act. We were founded on April 16, 2004, were initially funded on June 23, 2004 and completed our initial public offering on October 8, 2004. We are one of the largest BDCs with approximately $12 billion of total committed capital under management as of June 30, 2010, including available debt capacity (subject to leverage restrictions), funds managed or co-managed by us or our wholly owned subsidiary and funds managed or sub-managed by our wholly owned portfolio company, Ivy Hill Asset Management, L.P. ("IHAM").

              Ares Capital's investment objective is to generate both current income and capital appreciation through debt and equity investments. We invest primarily in U.S. middle-market companies, where we believe the supply of primary capital is limited and the investment opportunities are most attractive. However, we may from time to time invest in larger companies. In this prospectus supplement, we generally use the term "middle market" to refer to companies with annual EBITDA between $10 million and $250 million. As used herein, EBITDA represents net income before net interest expense, income tax expense, depreciation and amortization.

              On April 1, 2010, we consummated the Allied Acquisition in an all stock merger whereby each existing share of common stock of Allied Capital was exchanged for 0.325 shares of our common stock. The Allied Acquisition was valued at approximately $908 million as of April 1, 2010. In connection therewith, we issued approximately 58.5 million shares of our common stock to Allied Capital's then-existing stockholders, thereby resulting in our then-existing stockholders owning approximately 69% of the combined company and the then-existing Allied Capital stockholders owning approximately 31% of the combined company. For a description of the risks that the Company may face as a result of the Allied Acquisition, see in the accompanying prospectus "Risk Factors—Risks Relating to Our Business—We may be unable to realize the benefits anticipated by the Allied Acquisition, including estimated cost savings and synergies, or it may take longer than anticipated to achieve such benefits."

S-6


Table of Contents

              We invest primarily in first and second lien senior loans and mezzanine debt, which in some cases includes an equity component. First and second lien senior loans generally are senior debt instruments that rank ahead of subordinated debt of a given portfolio company. These loans also have the benefit of security interests on the assets of the portfolio company, which may rank ahead of or be junior to other security interests. Mezzanine debt is subordinated to senior loans and is generally unsecured. Our investments have ranged between $20 million and $200 million each, although the investment sizes may be more or less than the targeted range. Our investment sizes are expected to grow with our capital availability.

              To a lesser extent, we also make equity investments, which have generally been non-control equity investments of less than $20 million (usually in conjunction with a concurrent loan investment). However, we may increase the size or nature of these investments. Also, as a result of the Allied Acquisition, Allied Capital's equity investments, including equity investments larger than those we have historically made and controlled portfolio company equity investments, became part of our portfolio. We intend to actively seek opportunities over time to dispose of certain of these investments and rotate them into higher-yielding first and second lien senior loans and mezzanine debt investments. However, there can be no assurance that this strategy will be successful. For risks relating to these investments, see in the accompanying prospectus "Risk Factors—Risks Relating to Our Investments—Investments in equity securities involve a substantial degree of risk."

              The proportion of these investments will change over time given our views on, among other things, the economic and credit environment we are operating in. In connection with our investing activities, we may make commitments with respect to indebtedness or securities of a potential portfolio company substantially in excess of our final investment. In such situations, while we may initially agree to fund up to a certain dollar amount of an investment, we may syndicate a portion of such amount to third parties, such that we make a smaller investment than what was reflected in our original commitment.

              The first and second lien senior loans generally have stated terms of three to 10 years and the mezzanine debt investments generally have stated terms of up to 10 years, but the expected average life of such first and second lien loans and mezzanine debt is generally between three and seven years. However, we may invest in securities with any maturity or duration. The debt that we invest in typically is not initially rated by any rating agency, but we believe that if such investments were rated, they would be below investment grade (rated lower than "Baa3" by Moody's Investors Service, lower than "BBB-" by Fitch Ratings or lower than "BBB-" by Standard & Poor's). We may invest without limit in debt of any rating, as well as debt that has not been rated by any nationally recognized statistical rating organization.

              We believe that our investment adviser, Ares Capital Management, is able to leverage Ares' current investment platform, resources and existing relationships with financial sponsors, financial institutions, hedge funds and other investment firms to provide us with attractive investments. In addition to deal flow, the Ares investment platform assists our investment adviser in analyzing, structuring and monitoring investments. Ares has been in existence for more than 12 years and its senior principals have an average of over 20 years experience investing in senior loans, high yield bonds, mezzanine debt and private equity securities. The Company has access to the Ares staff of approximately 140 investment professionals and approximately 190 administrative professionals employed by Ares who provide assistance in accounting, legal, compliance, operations, technology and investor relations.

              While our primary focus is to generate current income and capital appreciation through investments in first and second lien senior loans and mezzanine debt and, to a lesser extent, equity securities of eligible portfolio companies, we also may invest up to 30% of our portfolio in opportunistic investments of non-eligible portfolio companies. Specifically, as part of this 30% basket,

S-7


Table of Contents


we may invest in debt of middle-market companies located outside of the United States, in investment funds that are operating pursuant to certain exceptions to the Investment Company Act, in advisers to similar investment funds and in debt and equity of public companies that do not meet the definition of eligible portfolio companies because their market capitalization of publicly traded equity securities exceeds the levels provided for in the Investment Company Act. We expect that these public companies generally will have debt that may be non-investment grade. From time to time we may also invest in high yield bonds, which, depending on the issuer, may or may not be included in this 30% basket.

              We and GE Commercial Finance Investment Advisory Services LLC also co-manage an unconsolidated senior debt fund: the Senior Secured Loan Fund LLC, or the "Senior Secured Loan Fund" or "Senior Secured Loan Program." The Senior Secured Loan Fund was initially formed in December 2007 and has approximately $3.6 billion of committed capital, approximately $915 million in aggregate principal amount of which was funded as of June 30, 2010. Of the $2.7 billion of unfunded committed capital as of June 30, 2010, approximately $340 million would be funded by Ares Capital.

              We also manage an unconsolidated fund, AGILE Fund I, LLC (the "AGILE Fund"), and our wholly owned subsidiary A.C. Corporation manages three unconsolidated loan funds: Emporia Preferred Funding I, Ltd., Emporia Preferred Funding II, Ltd. and Emporia Preferred Funding III, Ltd. (collectively, the "Emporia Funds"). As of June 30, 2010, A.C. Corporation managed approximately $1.2 billion of committed capital.

              In addition, we have made investments in our portfolio company, IHAM, which manages five unconsolidated senior debt funds, Ivy Hill Middle Market Credit Fund, Ltd. ("Ivy Hill I"), Ivy Hill Middle Market Credit Fund II, Ltd. ("Ivy Hill II"), Ivy Hill Senior Debt Fund, L.P. and related vehicles ("Ivy Hill SDF" and, together with Ivy Hill I and Ivy Hill II, the "Ivy Hill Funds"), and Knightsbridge CLO 2007-1, Ltd. and Knightsbridge CLO 2008-1, Ltd. (the "Knightsbridge Funds"), and serves as the sub-adviser/sub-manager for four others: CoLTS 2005-1 Ltd., CoLTS 2005-2 Ltd. and CoLTS 2007-1 Ltd., or collectively, the "CoLTS Funds," and FirstLight Funding I, Ltd., or "FirstLight." As of June 30, 2010, IHAM had total committed capital under management of over $2.9 billion, which includes approximately $0.3 billion of capital committed by Ares Capital.

About Ares

              Founded in 1997, Ares is a global alternative asset manager and SEC registered investment adviser with approximately $37 billion of total committed capital under management and over 330 employees as of June 30, 2010.

              Ares specializes in originating and managing assets in both the leveraged finance and private equity markets. Ares' leveraged finance activities include the origination, acquisition and management of senior loans, high yield bonds, mezzanine debt and special situation investments. Ares' private equity activities focus on providing flexible, junior capital to middle-market companies. Ares has the ability to invest across a capital structure, from senior floating rate debt to common equity. This flexibility, combined with Ares' "buy and hold" philosophy, enables Ares to structure an investment to meet the specific needs of a company rather than the less flexible demands of the public markets.

              Ares is comprised of the following groups:

S-8


Table of Contents

              Ares senior principals have been working together as a group for many years and have an average of over 20 years of experience in leveraged finance, private equity, distressed debt, investment banking and capital markets. They are backed by a large team of highly disciplined professionals. Ares rigorous investment approach is based upon an intensive, independent financial analysis, with a focus on preservation of capital, diversification and active portfolio management. These fundamentals underlie Ares' investment strategy and have resulted in large pension funds, banks, insurance companies, endowments and high net worth individuals investing in Ares' funds.

Ares Capital Management

              Ares Capital Management, our investment adviser, is served by a dedicated origination and transaction development team of approximately 65 investment professionals led by the senior partners of Ares Capital Management, Michael Arougheti, Eric Beckman, Kipp deVeer, Mitchell Goldstein and Michael Smith. Ares Capital Management leverages off of Ares' entire investment platform and benefits from the significant capital markets, trading and research expertise of all of Ares' investment professionals. Ares funds currently hold over 1,000 investments in over 30 different industries. Ares Capital Management's investment committee has eight members, including the senior partners of Ares' Private Debt Group and certain senior partners of Ares' Capital Markets and Private Equity Groups.

Recent Developments

              As of September 30, 2010, we had made new investment commitments of $512 million, $494 million of which was funded, since June 30, 2010. Of these new investment commitments, 45% were in investments in first lien senior secured debt, 41% were in subordinated notes of the Senior Secured Loan Program, 8% were in senior subordinated debt, 4% were in equity securities and 2% were in second lien senior secured debt.

              As of September 30, 2010, we had exited $221 million of investments since June 30, 2010. Of these investments, 66% were in first lien senior secured debt, 28% were in senior subordinated debt and 6% were in second lien senior secured debt. Of the $221 million of investments exited since June 30, 2010, $95 million were investments acquired as part of the Allied Acquisition, including $23 million that were on non-accrual status.

              In addition, as of September 30, 2010, we had an investment backlog and pipeline of $469 million and $428 million, respectively. We may syndicate a portion of these investments and commitments to third parties. The consummation of any of the investments in this backlog and pipeline depends upon, among other things: satisfactory completion of our due diligence investigation of the prospective portfolio company, our acceptance of the terms and structure of such investment and the execution and delivery of satisfactory transaction documentation. We cannot assure you that we will

make any of these investments or that we will syndicate any portion of such investments and commitments.

RISK FACTORS

The Notes will be unsecured and therefore will be effectively subordinated to any secured indebtedness we may incur.

              The Notes will not be secured by any of our assets or any of the assets of our subsidiaries. As a result, the Notes are effectively subordinated to any secured indebtedness we or our subsidiaries have currently incurred and may incur in the future (or any indebtedness that is initially unsecured to which we subsequently grant security) to the extent of the value of the assets securing such indebtedness. In any liquidation, dissolution, bankruptcy or other similar proceeding, the holders of any of our existing or future secured indebtedness and the secured indebtedness of our subsidiaries may assert rights against the assets pledged to secure that indebtedness in order to receive full payment of their indebtedness before the assets may be used to pay other creditors, including the holders of the Notes. As of September 30, 2010, we had $431.0 million outstanding under the Revolving Credit Facility. The Revolving Credit Facility is secured by certain of our assets and the indebtedness thereunder is therefore effectively senior to the Notes to the extent of the value of such assets.

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

              The Notes are obligations exclusively of Ares Capital and not of any of our subsidiaries. None of our subsidiaries is a guarantor of the Notes and the Notes are not required to be guaranteed by any subsidiaries we may acquire or create in the future. A significant portion of our indebtedness is held through subsidiary financing vehicles and secured by certain assets of ours or our subsidiaries. For example, our secured indebtedness with respect to the CP Funding Facility and the Debt Securitization are each held through our wholly owned subsidiaries, Ares Capital CP Funding LLC and ARCC Commercial Loan Trust 2006, respectively. See "Management's Discussion and Analysis of Financial Condition and Results of Operations—Financial Condition, Liquidity and Capital Resources—Debt Capital Activities" in the accompanying prospectus for more detail on the CP Funding Facility and the Debt Securitization.

              Except to the extent we are a creditor with recognized claims against our subsidiaries, all claims of creditors (including trade creditors) and holders of preferred stock, if any, of our subsidiaries will have priority over our claims (and therefore the claims of our creditors, including holders of the Notes) with respect to the assets of such subsidiaries. Even if we are recognized as a creditor of one or more of our subsidiaries, our claims would still be effectively subordinated to any security interests in the assets of any such subsidiary and to any indebtedness or other liabilities of any such subsidiary senior to our claims. Consequently, the Notes will be structurally subordinated to all indebtedness and other liabilities (including trade payables) of any of our subsidiaries and any subsidiaries that we may in the future acquire or establish as financing vehicles or otherwise. As of September 30, 2010, we had $283.4 million outstanding under the CP Funding Facility. As of September 30, 2010, we also had outstanding $177.2 million of CLO Notes that mature on December 20, 2019. All of such indebtedness would be structurally senior to the Notes. In addition, our subsidiaries may incur substantial additional indebtedness in the future, all of which would be structurally senior to the Notes.

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

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

S-11


Table of Contents

              In addition, the indenture will not require us to offer to purchase the Notes in connection with a change of control or any other event.

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

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

              Certain of our current debt instruments include more protections for their holders than the indenture and the Notes. See in the accompanying prospectus "Risk Factors—Risks Relating to Our Business—In addition to regulatory requirements that restrict our ability to raise capital, the Facilities, the CLO Notes and the Unsecured Notes contain various covenants which, if not complied with, could accelerate repayment under the Facilities, the CLO Notes and the Unsecured Notes, thereby materially and adversely affecting our liquidity, financial condition and results of operations." In addition, other debt we issue or incur in the future could contain more protections for its holders than the indenture and the Notes, including additional covenants and events of default. The issuance or incurrence of any such debt with incremental protections could affect the market for and trading levels and prices of the Notes.

An active trading market for the Notes may not develop, which could limit the market price of the Notes or your ability to sell them. Because one rating agency has assigned the Notes a non-investment grade rating, the Notes may be subject to greater price volatility than similar securities without such a rating.

              The Notes are a new issue of debt securities for which there currently is no trading market. Although we expect the Notes to be listed on The New York Stock Exchange, we cannot provide any

S-12


Table of Contents


assurances that an active trading market will develop for the Notes or that you will be able to sell your Notes. If the Notes are traded after their initial issuance, they may trade at a discount from their initial offering price depending on prevailing interest rates, the market for similar securities, our credit ratings, general economic conditions, our financial condition, performance and prospects and other factors. Moreover, because one rating agency has assigned the Notes a non-investment grade rating, the Notes may be subject to greater price volatility than securities of similar maturity without such a non-investment grade rating. The underwriters have advised us that they intend to make a market in the Notes, but they are not obligated to do so. The underwriters may discontinue any market-making in the Notes at any time at their sole discretion. Accordingly, we cannot assure you that a liquid trading market will develop for the Notes, that you will be able to sell your Notes at a particular time or that the price you receive when you sell will be favorable. To the extent an active trading market does not develop, the liquidity and trading price for the Notes may be harmed. Accordingly, you may be required to bear the financial risk of an investment in the Notes for an indefinite period of time.

USE OF PROCEEDS

              We estimate that the net proceeds we will receive from the sale of the $200.0 million aggregate principal amount of Notes in this offering will be approximately $193.2 million (or approximately $222.2 million if the underwriters fully exercise their overallotment option), in each case at a public offering price of 100% of par, after deducting the underwriting discounts and commissions of $6.3 million (or approximately $7.2 million if the underwriters fully exercise their overallotment option) payable by us and estimated offering expenses of approximately $0.5 million payable by us.

              We expect to use the net proceeds of this offering to repay or repurchase certain outstanding indebtedness under the Revolving Credit Facility ($431.0 million outstanding as of September 30, 2010). The interest charged on the indebtedness incurred under the Revolving Credit Facility is based on LIBOR (one, two, three or six month) plus an applicable spread of between 2.50% and 4.00%. As of September 30, 2010, the one, two, three and six month LIBOR were 0.26%, 0.27%, 0.29% and 0.46%, respectively, and the applicable spread was 3.00%. The Revolving Credit Facility matures on January 22, 2013.

              We intend to use any net proceeds from this offering that are not applied as described above for general corporate purposes, which include investing in portfolio companies in accordance with our investment objective and strategies and market conditions. Investing in portfolio companies could include investments in our investment backlog and pipeline that as of September 30, 2010, were approximately $469 million and $428 million, respectively. The consummation of any of the investments in this backlog and pipeline depends upon, among other things: satisfactory completion of our due diligence investigation of the prospective portfolio company, our acceptance of the terms and structure of such investment and the execution and delivery of satisfactory transaction documentation, and there can be no guarantee that we will consummate any of these investments. Our primary focus is to generate current income and capital appreciation through investments in first and second lien senior loans and mezzanine debt, and, to a lesser extent, equity securities of eligible portfolio companies. In addition to such investments, we may invest up to 30% of our portfolio in opportunistic investments of non-eligible portfolio companies. As part of this 30%, we may invest in debt of middle-market companies located outside of the United States. Pending such investments, we will invest a portion of the net proceeds primarily in cash, cash equivalents, U.S. government securities and other high-quality short-term investments. These securities may earn yields substantially lower than the income that we anticipate receiving once we are fully invested in accordance with our investment objective. As a result, we may not be able to achieve our investment objective and/or pay any dividends during this period or, if we are able to do so, such dividends may be substantially lower than the dividends that we expect to pay when our portfolio is fully invested. If we do not realize yields in excess of our expenses, we may incur operating losses and the market price of our shares may decline. See "Regulation—Temporary Investments" in the accompanying prospectus for additional information about temporary investments we may make while waiting to make longer-term investments in pursuit of our investment objective.

UNITED STATES FEDERAL INCOME TAX CONSEQUENCES

              The following discussion is a general summary of the material United States federal income tax considerations (and, in the case of a non-U.S. holder (as defined below), the material United States federal estate tax consequences) applicable to an investment in the Notes. This summary does not purport to be a complete description of the income tax considerations applicable to such an investment. The discussion is based upon the Internal Revenue Code of 1986, as amended (the "Code"), Treasury Regulations, and administrative and judicial interpretations, each as of the date of this prospectus supplement and all of which are subject to change, potentially with retroactive effect. You should consult your own tax advisor with respect to tax considerations that pertain to your purchase of our Notes.

              This discussion deals only with Notes held as capital assets within the meaning of Section 1221 of the Code and does not purport to deal with persons in special tax situations, such as financial institutions, insurance companies, controlled foreign corporations, passive foreign investment companies and regulated investment companies (and shareholders of such corporations), dealers in securities or currencies, traders in securities, former citizens of the United States, persons holding the Notes as a hedge against currency risks or as a position in a "straddle," "hedge," "constructive sale transaction" or "conversion transaction" for tax purposes, entities that are tax-exempt for United States federal income tax purposes, retirement plans, individual retirement accounts, tax-deferred accounts, persons subject to the alternative minimum tax, pass-through entities (including partnerships and entities and arrangements classified as partnerships for United States federal income tax purposes) and beneficial owners of pass-through entities, or persons whose functional currency is not the U.S. dollar. It also does not deal with beneficial owners of the Notes other than original purchasers of the Notes who acquire the Notes in this offering for a price equal to their original issue price (as defined below). If you are considering purchasing the Notes, you should consult your own tax advisor concerning the application of the United States federal tax laws to you in light of your particular situation, as well as any consequences to you of purchasing, owning and disposing of the Notes under the laws of any other taxing jurisdiction.

              For purposes of this discussion, the term "U.S. holder" means a beneficial owner of a Note that is, for United States federal income tax purposes, (i) an individual citizen or resident of the United States, (ii) a corporation or other entity treated as a corporation for United States federal income tax purposes, created or organized in or under the laws of the United States or of any political subdivision thereof, (iii) a trust (a) subject to the control of one or more United States persons and the primary supervision of a court in the United States, or (b) that has a valid election (under applicable Treasury Regulations) to be treated as a United States person, or (iv) an estate the income of which is subject to United States federal income taxation regardless of its source. The term "non-U.S. holder" means a beneficial owner of a Note that is neither a U.S. holder nor a partnership (including an entity or arrangement treated as a partnership for U.S. federal income tax purposes). An individual may, subject to exceptions, be deemed to be a resident alien, as opposed to a non-resident alien, by, among other ways, being present in the United States (i) on at least 31 days in the calendar year, and (ii) for an aggregate of at least 183 days during a three-year period ending in the current calendar year, counting for such purposes all of the days present in the current year, one-third of the days present in the immediately preceding year, and one-sixth of the days present in the second preceding year. Resident aliens are subject to United States federal income tax as if they were United States citizens.

              If a partnership (including an entity or arrangement treated as a partnership for U.S. federal income tax purposes) holds any Notes, the United States federal income tax treatment of a partner of the partnership generally will depend upon the status of the partner, the activities of the partnership and certain determinations made at the partner level. Partners of partnerships holding Notes should consult their own tax advisors.

Taxation of Note Holders

              Under present law, we are of the opinion that the Notes will constitute indebtedness of us for United States federal income tax purposes, which the below discussion assumes. We intend to treat all payments made with respect to the Notes consistent with this characterization.

              Payments or accruals of interest on a Note generally will be taxable to a U.S. holder as ordinary interest income at the time they are received (actually or constructively) or accrued, in accordance with the U.S. holder's regular method of tax accounting.

              Upon the sale, exchange, redemption or retirement of a Note, a U.S. holder generally will recognize capital gain or loss equal to the difference between the amount realized on the sale, exchange, redemption or retirement (excluding amounts representing accrued and unpaid interest, which are treated as ordinary income) and the U.S. holder's adjusted tax basis in the Note. A U.S. holder's adjusted tax basis in a Note generally will equal the U.S. holder's initial investment in the Note. Capital gain or loss generally will be long-term capital gain or loss if the Note was held for more than one year. Long-term capital gains recognized by individuals and certain other non-corporate U.S. holders generally are eligible for reduced rates of taxation. The distinction between capital gain or loss and ordinary income or loss is also important in other contexts; for example, for purposes of the limitations on a U.S. holder's ability to offset capital losses against ordinary income.

              Newly enacted legislation may require certain noncorporate U.S. holders to pay a 3.8% Medicare tax on, among other things, interest on and capital gains from the sale, exchange, redemption or retirement of the Notes. This legislation would apply for taxable years beginning after December 31, 2012. U.S. holders should consult their own tax advisors regarding the effect, if any, of this legislation on their ownership and disposition of the Notes.

              Taxation of Non-U.S. Holders.    A non-U.S. holder generally will not be subject to United States federal income or withholding taxes on payments of principal or interest on a Note provided that (i) income on the Note is not effectively connected with the conduct by the non-U.S. holder of a trade or business within the United States, (ii) the non-U.S. holder is not a controlled foreign corporation related to the Company through stock ownership, (iii) in the case of interest income, the recipient is not a bank receiving interest described in Section 881(c)(3)(A) of the Code, (iv) the non-U.S. holder does not own (actually or constructively) 10% or more of the total combined voting power of all classes of stock of the Company, and (v) the non-U.S. holder provides a statement on an Internal Revenue Service (IRS) Form W-8BEN (or other applicable form) signed under penalties of perjury that includes its name and address and certifies that it is not a United States person in compliance with applicable requirements, or satisfies documentary evidence requirements for establishing that it is a non-U.S. holder.

              A non-U.S. holder that is not exempt from tax under these rules generally will be subject to United States federal income tax withholding on payments of interest on the Notes at a rate of 30% unless (i) the income is effectively connected with the conduct of a United States trade or business, in which case the interest will be subject to United States federal income tax on a net income basis as applicable to U.S. holders generally (unless an applicable income tax treaty provides otherwise), or (ii) an applicable income tax treaty provides for a lower rate of, or exemption from, withholding tax.

              In the case of a non-U.S. holder that is a corporation and that receives income that is effectively connected with the conduct of a United States trade or business, such income may also be subject to a branch profits tax (which is generally imposed on a non-U.S. corporation on the actual or deemed repatriation from the United States of earnings and profits attributable to a United States trade or business) at a 30% rate. The branch profits tax may not apply (or may apply at a reduced rate) if the non-U.S. holder is a qualified resident of a country with which the United States has an income tax treaty.

S-16


Table of Contents

              To claim the benefit of an income tax treaty or to claim exemption from withholding because income is effectively connected with a United States trade or business, the non-U.S. holder must timely provide the appropriate, properly executed IRS forms. These forms may be required to be periodically updated. Also, a non-U.S. holder who is claiming the benefits of a treaty may be required to obtain a United States taxpayer identification number and to provide certain documentary evidence issued by foreign governmental authorities to prove residence in the foreign country.

              Generally, a non-U.S. holder will not be subject to United States federal income or withholding taxes on any amount that constitutes capital gain upon the sale, exchange, redemption or retirement of a Note, provided the gain is not effectively connected with the conduct of a trade or business in the United States by the non-U.S. holder (and, if required by an applicable income tax treaty, is not attributable to a United States "permanent establishment" maintained by the non-U.S. holder). Certain other exceptions may be applicable, and a non-U.S. holder should consult its tax advisor in this regard.

              A Note that is held by an individual who, at the time of death, is not a citizen or resident of the United States (as specially defined for United States federal estate tax purposes) generally will not be subject to the United States federal estate tax, unless, at the time of death, (i) such individual directly or indirectly, actually or constructively, owns ten percent or more of the total combined voting power of all classes of our stock entitled to vote within the meaning of Section 871(h)(3) of the Code and the Treasury Regulations thereunder or (ii) such individual's interest in the Notes is effectively connected with the individual's conduct of a United States trade or business.

              Information Reporting and Backup Withholding.    A U.S. holder (other than an "exempt recipient," including a corporation and certain other persons who, when required, demonstrate their exempt status) may be subject to backup withholding at a rate of 28% (which rate currently is scheduled to increase to 31% for taxable years beginning on or after January 1, 2011) on, and to information reporting requirements with respect to, payments of principal or interest on, and proceeds from the sale, exchange, redemption or retirement of, the Notes. In general, if a non-corporate U.S. holder subject to information reporting fails to furnish a correct taxpayer identification number or otherwise fails to comply with applicable backup withholding requirements, backup withholding at the applicable rate may apply. Non-U.S. holders generally are exempt from information reporting and backup withholding, provided, if necessary, that they demonstrate their qualification for exemption.

              You should consult your tax advisor regarding the qualification for an exemption from backup withholding and information reporting and the procedures for obtaining such an exemption, if applicable. Any amounts withheld under the backup withholding rules from a payment to a beneficial owner generally would be allowed as a refund or a credit against such beneficial owner's United States federal income tax provided the required information is timely furnished to the IRS.

You should consult your own tax advisor with respect to the particular tax consequences to you of an investment in our Notes, including the possible effect of any pending legislation or proposed regulations.

              Subject to the terms and conditions set forth in the purchase agreement, the underwriters have agreed, severally and not jointly, to purchase all of the Notes sold under the purchase agreement if any of these Notes are purchased. If an underwriter defaults, the purchase agreement provides that the purchase commitments of the nondefaulting underwriters may be increased or the purchase agreement may be terminated.

              We have agreed to indemnify the 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.

              The underwriters are offering the Notes, subject to prior sale, when, as and if issued to and accepted by them, subject to approval of legal matters by counsel, including the validity of the shares, and other conditions contained in the purchase agreement, such as the receipt by the underwriters of officer's certificates and legal opinions. The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.

              We expect that delivery of the Notes will be made against payment therefor on or about October 21, 2010, which will be the fifth business day following the date of the pricing of the Notes (such settlement being herein referred to as "T+5"). Under Rule 15c6-1 under the Securities Exchange Act of 1934, as amended, trades in the secondary market generally are required to settle in three business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers

S-19


Table of Contents


who wish to trade the Notes prior to the date of delivery hereunder will be required, by virtue of the fact that the Notes initially will settle in T+5 business days, to specify an alternate settlement arrangement at the time of any such trade to prevent a failed settlement.

Commissions and Discounts

              An underwriting discount of 3.15% per Note will be paid by us. This underwriting discount will also apply to any Notes purchased pursuant to the overallotment option.

              The following table shows the total underwriting discounts and commissions that we are to pay to the underwriters in connection with this offering. The information assumes either no exercise or full exercise by the underwriters of their overallotment option.

 
  Per Note   Without Option   With Option  

Public offering price

    100.00 % $ 200,000,000   $ 230,000,000  

Underwriting discount

    3.15 % $ 6,300,000   $ 7,245,000  

Proceeds, before expenses, to us

    96.85 % $ 193,700,00   $ 222,755,000  

              The underwriters propose to offer some of the Notes to the public at the public offering price set forth on the cover page of this prospectus supplement and some of the Notes to certain other Financial Industry Regulatory Authority (FINRA) members at the public offering price less a concession not in excess of 2.00% of the aggregate principal amount of the Notes. The underwriters may allow, and the dealers may reallow, a discount not in excess of 1.80% of the aggregate principal amount of the Notes. After the initial offering of the Notes to the public, the public offering price and such concessions may be changed. No such change shall change the amount of proceeds to be received by us as set forth on the cover page of this prospectus supplement.

              The expenses of the offering, not including the underwriting discount, are estimated at $540,000 and are payable by us.

Overallotment Option

              We have granted an option to the underwriters to purchase up to an additional $30,000,000 aggregate principal amount of the Notes offered hereby at the public offering price within 30 days from the date of this prospectus supplement solely to cover any overallotments. If the underwriters exercise this option, each will be obligated, subject to conditions contained in the purchase agreement, to purchase a number of additional Notes proportionate to that underwriter's initial principal amount reflected in the above table.

No Sales of Similar Securities

              Subject to certain exceptions, we have agreed not to directly or indirectly, offer, pledge, sell, contract to sell, grant any option for the sale of, or otherwise transfer or dispose of any debt securities issued or guaranteed by the Company or any securities convertible into or exercisable or exchangeable for debt securities issued or guaranteed by the Company or file any registration statement under the 1933 Act with respect to any of the foregoing for a period of 90 days after the date of this prospectus supplement without first obtaining the written consent of the Representatives, other than certain private sales of debt securities to a limited number of institutional investors. This consent may be given at any time without public notice.

Listing

              The Notes are a new issue of securities with no established trading market. We intend to list the Notes on The New York Stock Exchange. We expect trading in the Notes on The New York Stock

S-20


Table of Contents


Exchange to begin within 30 days after the original issue date. Currently there is no public market for the Notes.

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

Price Stabilization, Short Positions

              In connection with the offering, the underwriters may purchase and sell Notes in the open market. These transactions may include overallotment, covering transactions and stabilizing transactions. Overallotment involves sales of securities in excess of the aggregate principal amount of securities to be purchased by the underwriters in the offering, which creates a short position for the underwriters. Covering transactions involve purchases of the securities in the open market after the distribution has been completed in order to cover short positions. Stabilizing transactions consist of certain bids or purchases of securities made for the purpose of preventing or retarding a decline in the market price of the securities while the offering is in progress.

              The underwriters also may 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 Notes sold by or for the account of such underwriter in stabilizing or short covering transactions.

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

Electronic Offer, Sale and Distribution of Notes

              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. The underwriters may allocate a limited principal amount of the Notes for sale to their online brokerage customers.

Other Relationships

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

              Affiliates of the underwriters are limited partners of private investment funds affiliated with our investment adviser, Ares Capital Management LLC.

              The underwriters or their affiliates may also trade in our securities, securities of our portfolio companies or other financial instruments related thereto for their own accounts or for the account of

others and may extend loans or financing directly or through derivative transactions to Ares, Ares Capital, Ares Capital Management or any of the portfolio companies.

              We may purchase securities of third parties from the underwriters or their affiliates after the offering. However, we have not entered into any agreement or arrangement regarding the acquisition of any such securities, and we may not purchase any such securities. We would only purchase any such securities if—among other things—we identified securities that satisfied our investment needs and completed our due diligence review of such securities.

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

              A portion of the proceeds of this offering may be used to repay or repurchase outstanding indebtedness under our Revolving Credit Facility. Affiliates of certain of the underwriters serve as lenders under our credit facilities (including the Revolving Credit Facility) and are also lenders to private investment funds managed by Ivy Hill Asset Management L.P., our portfolio company. Accordingly, affiliates of the underwriters may receive a portion of the proceeds of this offering. Certain of the underwriters and their affiliates were underwriters in connection with our initial public offering and our subsequent common stock offerings and rights offering, for which they received customary fees.

              Frank E. O'Bryan, one of our independent directors, is a stockholder of the publicly traded parent company of one of the underwriters of this offering. As a result, Mr. O'Bryan may be considered an "interested person" of the Company during the pendency of this offering under relevant rules of the Investment Company Act.

              Ares Capital Corporation is a specialty finance company that is a closed-end, non-diversified management investment company incorporated in Maryland. We have elected to be regulated as a business development company under the Investment Company Act of 1940. Our investment objective is to generate both current income and capital appreciation through debt and equity investments. We invest primarily in first and second lien senior loans and mezzanine debt, which in some cases includes an equity component. To a lesser extent, we also make equity investments.

              We are externally managed by Ares Capital Management LLC, an affiliate of Ares Management LLC, a global alternative asset manager and a Securities and Exchange Commission ("SEC") registered investment adviser with approximately $37 billion of total committed capital under management as of June 30, 2010. Ares Operations LLC, an affiliate of Ares Management LLC, provides the administrative services necessary for us to operate.

              Our common stock is traded on The NASDAQ Global Select Market under the symbol "ARCC." On September 30, 2010, the last reported sales price of our common stock on The NASDAQ Global Select Market was $15.65 per share. The net asset value per share of our common stock at June 30, 2010 (the last date prior to the date of this prospectus on which we determined net asset value) was $14.11.

              Investing in our securities involves risks that are described in the "Risk Factors" section beginning on page 25 of this prospectus, including the risk of leverage.

The preferred stock, debt securities, subscription rights and warrants offered hereby may be convertible or exchangeable into shares of our common stock. The securities may be offered at prices and on terms to be described in one or more supplements to this prospectus.

PROSPECTUS SUMMARY

              This summary highlights some of the information contained elsewhere in this prospectus. It is not complete and may not contain all of the information that you may want to consider. You should read carefully the more detailed information set forth under "Risk Factors" and the other information included in this prospectus. Except where the context suggests otherwise, the terms "we," "us," "our," "the Company" and "Ares Capital" refer to Ares Capital Corporation and its consolidated subsidiaries; "Ares Capital Management" or "the investment adviser" refers to Ares Capital Management LLC; "Ares Operations" refers to Ares Operations LLC; and "Ares" refers to Ares Partners Management Company LLC ("APMC") and its affiliated companies (other than portfolio companies of its affiliated funds), including Ares Management LLC, which we refer to separately as "Ares Management."

              As described in more detail below, we consummated the acquisition (the "Allied Acquisition") of Allied Capital Corporation ("Allied Capital") on April 1, 2010. Other than as set forth in the pro forma financial information or otherwise specifically set forth herein, financial information presented herein for and as of periods ending on or prior to March 31, 2010 does not include any information in respect of Allied Capital. In addition, other than as set forth in the pro forma financial information or otherwise specifically set forth herein, financial information for the six months ended June 30, 2010, including, without limitation, with respect to the Company's consolidated statements of operations, stockholders' equity and cash flows, only includes results attributable to Allied Capital for the period beginning April 1, 2010.


THE COMPANY

              Ares Capital, a Maryland corporation, is a specialty finance company that is a closed-end, non-diversified management investment company. We have elected to be regulated as a business development company, or a "BDC," under the Investment Company Act of 1940, or the "Investment Company Act." We were founded on April 16, 2004, were initially funded on June 23, 2004 and completed our initial public offering on October 8, 2004. We are one of the largest BDCs with approximately $12 billion of total committed capital under management as of June 30, 2010, including available debt capacity (subject to leverage restrictions), funds co-managed by us and funds managed or sub-managed by our wholly owned portfolio company, Ivy Hill Asset Management, L.P. ("IHAM").

              Ares Capital's investment objective is to generate both current income and capital appreciation through debt and equity investments. We invest primarily in U.S. middle market companies, where we believe the supply of primary capital is limited and the investment opportunities are most attractive. However, we may from time to time invest in larger companies. In this prospectus, we generally use the term "middle market" to refer to companies with annual EBITDA between $10 million and $250 million. As used herein, EBITDA represents net income before net interest expense, income tax expense, depreciation and amortization.

              On April 1, 2010, we consummated the Allied Acquisition in an all stock merger whereby each existing share of common stock of Allied Capital was exchanged for 0.325 shares of our common stock. The Allied Acquisition was valued at approximately $908 million as of April 1, 2010. In connection therewith, we issued approximately 58.5 million shares of our common stock to Allied Capital's then-existing stockholders, thereby resulting in our then-existing stockholders owning approximately 69% of the combined company and the then-existing Allied Capital stockholders owning approximately 31% of the combined company. See "Risk Factors—Risks Relating to Our Business—We may be unable to realize the benefits anticipated by the Allied Acquisition, including estimated cost savings and synergies, or it may take longer than anticipated to achieve such benefits" for a description of the risks that the Company may face as a result of the Allied Acquisition.

              We invest primarily in first and second lien senior loans and mezzanine debt, which in some cases includes an equity component. First and second lien senior loans generally are senior debt instruments that rank ahead of subordinated debt of a given portfolio company. These loans also have

1


Table of Contents


the benefit of security interests on the assets of the portfolio company, which may rank ahead of or be junior to other security interests. Mezzanine debt is subordinated to senior loans and is generally unsecured. Our investments have ranged between $20 million and $200 million each, although the investment sizes may be more or less than the targeted range. Our investment sizes are expected to grow with our capital availability.

              To a lesser extent, we also make equity investments, which have generally been non-control equity investments of less than $20 million (usually in conjunction with a concurrent loan investment). However, we may increase the size or nature of these investments. Also, as a result of the Allied Acquisition, Allied Capital's equity investments, including equity investments larger than those we have historically made and controlled portfolio company equity investments, became part of our portfolio. We intend to actively seek opportunities over time to dispose of certain of these investments and rotate them into higher-yielding first and second lien senior loans and mezzanine debt investments. However, there can be no assurance that this strategy will be successful. For risks relating to these investments, see "Risk Factors—Risks Relating to Our Investments—Investments in equity securities involve a substantial degree of risk."

              The proportion of these investments will change over time given our views on, among other things, the economic and credit environment we are operating in. In connection with our investing activities, we may make commitments with respect to indebtedness or securities of a potential portfolio company substantially in excess of our final investment. In such situations, while we may initially agree to fund up to a certain dollar amount of an investment, we may syndicate a portion of such amount to third parties, such that we make a smaller investment than what was reflected in our original commitment.

              The first and second lien senior loans generally have stated terms of three to 10 years and the mezzanine debt investments generally have stated terms of up to 10 years, but the expected average life of such first and second lien loans and mezzanine debt is generally between three and seven years. However, we may invest in securities with any maturity or duration. The debt that we invest in typically is not initially rated by any rating agency, but we believe that if such investments were rated, they would be below investment grade (rated lower than "Baa3" by Moody's Investors Service, lower than "BBB-" by Fitch Ratings or lower than "BBB-" by Standard & Poor's). We may invest without limit in debt of any rating, as well as debt that has not been rated by any nationally recognized statistical rating organization.

              We believe that our investment adviser, Ares Capital Management, is able to leverage Ares' current investment platform, resources and existing relationships with financial sponsors, financial institutions, hedge funds and other investment firms to provide us with attractive investments. In addition to deal flow, the Ares investment platform assists our investment adviser in analyzing, structuring and monitoring investments. Ares has been in existence for more than 12 years and its senior principals have an average of over 20 years experience investing in senior loans, high yield bonds, mezzanine debt and private equity securities. The Company has access to the Ares staff of approximately 140 investment professionals and approximately 190 administrative professionals employed by Ares who provide assistance in accounting, legal, compliance, operations, technology and investor relations.

              While our primary focus is to generate current income and capital appreciation through investments in first and second lien senior loans and mezzanine debt and, to a lesser extent, equity securities of eligible portfolio companies, we also may invest up to 30% of our portfolio in opportunistic investments of non-eligible portfolio companies. Specifically, as part of this 30% basket, we may invest in debt of middle market companies located outside of the United States, in investment funds that are operating pursuant to certain exceptions to the Investment Company Act, in advisers to similar investment funds and in debt and equity of public companies that do not meet the definition of

2


Table of Contents


eligible portfolio companies because their market capitalization of publicly traded equity securities exceeds the levels provided for in the Investment Company Act. We expect that these public companies generally will have debt that may be non-investment grade. From time to time we may also invest in high yield bonds, which, depending on the issuer, may or may not be included in this 30% basket.

              We and GE Commercial Finance Investment Advisory Services LLC also co-manage an unconsolidated senior debt fund: the Senior Secured Loan Fund LLC (formerly known as the Unitranche Fund LLC), or the "Senior Secured Loan Fund."

              We also manage an unconsolidated fund, AGILE Fund I, LLC (the "AGILE Fund"), and our wholly owned subsidiary A.C. Corporation manages three unconsolidated loan funds: Emporia Preferred Funding I, Ltd., Emporia Preferred Funding II, Ltd. and Emporia Preferred Funding III, Ltd. (collectively, the "Emporia Funds").

              In addition, we have made investments in our portfolio company, IHAM, which manages five unconsolidated senior debt funds, Ivy Hill Middle Market Credit Fund, Ltd. ("Ivy Hill I"), Ivy Hill Middle Market Credit Fund II, Ltd. ("Ivy Hill II"), Ivy Hill Senior Debt Fund, L.P. and related vehicles ("Ivy Hill SDF" and, together with Ivy Hill I and Ivy Hill II, the "Ivy Hill Funds"), and Knightsbridge CLO 2007-1, Ltd. and Knightsbridge CLO 2008-1, Ltd. (the "Knightsbridge Funds"), and serves as the sub-adviser/sub-manager for four others: CoLTS 2005-1 Ltd., CoLTS 2005-2 Ltd. and CoLTS 2007-1 Ltd., or collectively, the "CoLTS Funds," and FirstLight Funding I, Ltd., or "FirstLight." As of June 30, 2010, IHAM had total committed capital under management of over $2.9 billion, which includes approximately $0.3 billion of capital committed by Ares Capital.

About Ares

              Founded in 1997, Ares is a global alternative asset manager and SEC registered investment adviser with approximately $37 billion of total committed capital under management and over 330 employees as of June 30, 2010.

              Ares specializes in originating and managing assets in both the leveraged finance and private equity markets. Ares' leveraged finance activities include the origination, acquisition and management of senior loans, high yield bonds, mezzanine debt and special situation investments. Ares' private equity activities focus on providing flexible, junior capital to middle market companies. Ares has the ability to invest across a capital structure, from senior floating rate debt to common equity. This flexibility, combined with Ares' "buy and hold" philosophy, enables Ares to structure an investment to meet the specific needs of a company rather than the less flexible demands of the public markets.

              Ares is comprised of the following groups:

3


Table of Contents

              Ares' senior principals have been working together as a group for many years and have an average of over 20 years of experience in leveraged finance, private equity, distressed debt, investment banking and capital markets. They are backed by a large team of highly disciplined professionals. Ares' rigorous investment approach is based upon an intensive, independent financial analysis, with a focus on preservation of capital, diversification and active portfolio management. These fundamentals underlie Ares' investment strategy and have resulted in large pension funds, banks, insurance companies, endowments and high net worth individuals investing in Ares' funds.

Ares Capital Management

              Ares Capital Management, our investment adviser, is served by a dedicated origination and transaction development team of approximately 65 investment professionals led by the senior partners of Ares Capital Management: Michael Arougheti, Eric Beckman, Kipp deVeer, Mitchell Goldstein and Michael Smith. Ares Capital Management leverages off of Ares' entire investment platform and benefits from the significant capital markets, trading and research expertise of Ares' investment professionals. Ares funds currently hold over 1,000 investments in over 30 different industries. Ares Capital Management's investment committee has nine members, including the senior partners of Ares Capital Management and certain Senior Partners of Ares' Capital Markets Group, Private Equity Group and the Managing Director of ACE.

MARKET OPPORTUNITY

              We believe there are opportunities for us to invest in middle market companies for the following reasons:

Table of Contents

COMPETITIVE ADVANTAGES

              We believe that we have the following competitive advantages over other capital providers to middle market companies:

Existing Investment Platform

              As of June 30, 2010, Ares managed approximately $37 billion of total committed capital under management in the related asset classes of non-syndicated first and second lien senior loans, syndicated loans, high yield bonds, mezzanine debt and private equity. We believe Ares' current investment platform provides a competitive advantage in terms of access to origination and marketing activities and diligence for Ares Capital. Specifically, the Ares platform provides the Company an advantage through its deal flow generation and investment evaluation process. Ares' asset management platform also provides additional market information, company knowledge and industry insight that benefit the investment and due diligence process. Ares' professionals maintain extensive financial sponsor and intermediary relationships, which provide valuable insight and access to transactions and information.

Seasoned Management Team

              Ares' senior professionals have an average of over 20 years of experience in leveraged finance, including substantial experience in investing in leveraged loans, high yield bonds, mezzanine debt, distressed debt and private equity securities. Ares Capital Management's investment professionals and members of its investment committee also have significant experience investing across market cycles. As a result of Ares' extensive investment experience and the history of its seasoned management team, Ares has developed a strong reputation across U.S. and European capital markets. We believe that Ares' long history in the leveraged loan market and the extensive experience of the principals investing across market cycles provides Ares Capital Management with a competitive advantage in identifying, investing in, and managing a portfolio of investments in middle market companies.

Experience and Focus on Middle Market Companies

              Ares has historically focused on investments in middle market companies and we benefit from this experience. In sourcing and analyzing deals, our investment adviser uses Ares' extensive network of relationships with intermediaries focused on middle market companies, including management teams, members of the investment banking community, private equity groups and other investment firms with whom Ares has long relationships. We believe this network enables us to attract well-positioned prospective portfolio company investments. Our investment adviser works closely with the Ares investment professionals, who oversee a portfolio of investments in over 1,000 companies and provide access to an extensive network of relationships and insights into industry trends and the state of the capital markets.

Disciplined Investment Philosophy

              In making its investment decisions, our investment adviser has adopted Ares' long-standing, consistent credit-based investment approach that was developed over 19 years ago by its founders. Specifically, Ares Capital Management's investment philosophy, portfolio construction and portfolio management involve an assessment of the overall macroeconomic environment, financial markets and company-specific research and analysis. Its investment approach emphasizes capital preservation, low volatility and minimization of downside risk. In addition to engaging in extensive due diligence from the perspective of a long-term investor, Ares Capital Management's approach seeks to reduce risk in investments by focusing on:

Extensive Industry Focus

              We concentrate our investing activities in industries with a history of predictable and dependable cash flows and in which the Ares investment professionals have had extensive investment experience. Since its inception in 1997, Ares investment professionals have invested in over 30 different industries. Ares investment professionals have developed long-term relationships with management teams and management consultants in these industries and have accumulated substantial information and identified potential trends within these industries. The experience of Ares' investment professionals investing across these industries throughout various stages of the economic cycle provides our investment adviser with access to market insights and investment opportunities.

Flexible Transaction Structuring

              We are flexible in structuring investments, including the types of securities in which we invest and the terms associated with such investments. Our investment adviser and its affiliates have extensive experience investing in a wide variety of securities for leveraged companies with a diverse set of terms and conditions. We believe this approach and experience enables our investment adviser to identify attractive investment opportunities throughout economic cycles and across a company's capital structure so we can make investments consistent with our stated investment objective and preserve principal while seeking appropriate risk adjusted returns. In addition, we have the ability to provide "one stop" financing with the ability to invest capital across the balance sheet and hold and syndicate larger investments than many of our competitors. The ability to underwrite, syndicate and hold larger investments benefits our stockholders by (a) potentially increasing net income and earnings through syndication, (b) increasing originated deal flow flexibility, (c) broadening market relationships and deal flow, (d) allowing us to optimize our portfolio composition and (e) allowing us to provide capital to middle market companies, which we believe currently have limited access to capital from traditional lending sources. We believe that the ability to provide capital at every level provides a strong value proposition to middle market borrowers and our senior debt capabilities provide superior deal origination and relative value analysis capabilities compared to traditional "mezzanine only" lenders.

Table of Contents

Broad Origination Strategy

              Our investment adviser focuses on self-originating most of our investments by identifying a broad array of investment opportunities across multiple channels. It also leverages off of the extensive relationships of the broader Ares platform, including relationships with the companies in the funds managed by IHAM, to identify investment opportunities. We believe that this allows for asset selectivity and that there is a significant relationship between proprietary deal origination and credit performance. We believe that our focus on generating proprietary deal flow and lead investing also gives us greater control over capital structure, deal terms, pricing and documentation and provides us with the ability to actively manage our investments. Moreover, by leading the investment process, our investment adviser is often able to secure controlling positions in credit tranches, thereby providing additional control in investment outcomes. Our investment adviser also has originated substantial proprietary deal flow from middle market intermediaries, which often allows us to act as the sole or principal source of institutional capital to the borrower.

OPERATING AND REGULATORY STRUCTURE

              Our investment activities are managed by Ares Capital Management and supervised by our board of directors, a majority of whom are independent of Ares and its affiliates. Ares Capital Management is an investment adviser that is registered under the Investment Advisers Act of 1940, or the "Advisers Act." Under our amended and restated investment advisory and management agreement, referred to herein as our "investment advisory and management agreement," we have agreed to pay Ares Capital Management an annual base management fee based on our total assets, as defined under the Investment Company Act (other than cash and cash equivalents but including assets purchased with borrowed funds), and an incentive fee based on our performance. See "Management—Investment Advisory and Management Agreement."

              As a BDC, we are required to comply with certain regulatory requirements. While we are permitted to finance investments using debt, our ability to use debt is limited in certain significant respects. See "Regulation." We have elected to be treated for U.S. federal income tax purposes as a regulated investment company, or a "RIC," under Subchapter M of the Internal Revenue Code of 1986, or the "Code." See "Certain Material U.S. Federal Income Tax Considerations."

MARKET CONDITIONS

              Due to volatility in global markets, the availability of capital and access to capital markets has been limited over the last two years. We have responded to constraints on raising new capital by pursuing other avenues of liquidity and growth, such as adjusting the pace of our investments, becoming more selective in evaluating investment opportunities, pursuing asset sales, developing our third-party asset management capabilities and/or reinvesting the proceeds from sales of lower yielding investments into higher yielding investments. We also intend to continue pursuing opportunities to manage third-party funds. As the global liquidity situation and market conditions evolve, we will continue to monitor and adjust our approach to funding accordingly. However, given the unprecedented nature of the volatility in the global markets, there can be no assurances that these activities will be successful. While levels of market disruption and volatility have improved, there can be no assurance that they will not worsen. If they do, we could face materially higher financing costs. Consequently, our operating strategy could be materially and adversely affected.

              Consistent with the volatile market conditions of the general economy, during 2008 and much of 2009, the stocks of BDCs as an industry traded at near historic lows as a result of concerns over liquidity, credit quality, leverage restrictions and distribution requirements. As a result of this market volatility, several of our peers are no longer active in the market and are winding down their investments, have defaulted on their indebtedness and/or have decreased their distributions to

stockholders. While market conditions have improved, we cannot assure you that the market pressures we face will not have a material adverse effect on our business, financial condition and results of operations.

              See "Risk Factors—Risks Relating to Our Business—Capital markets have recently been in a period of disruption and instability. These market conditions have materially and adversely affected debt and equity capital markets in the United States, which has had, and may in the future have, a negative impact on our business and operations."

ACQUISITION OPPORTUNITIES

              We believe that the dislocation in the credit markets has created compelling risk adjusted returns in both the primary and secondary markets. Further, the current dislocation and illiquidity in the credit markets has also increased the likelihood of further consolidation in our industry. To that end, over the past 12-18 months we and our portfolio company IHAM have evaluated (and expect to continue to evaluate in the future) a number of potential strategic acquisition opportunities, including acquisitions of:

              For example, in June 2009 our portfolio company IHAM completed the acquisition of contracts to sub-manage approximately $770 million of middle market loan assets in three CLO vehicles managed by affiliates of Wells Fargo & Company. IHAM also acquired certain equity interests in these three CLOs. On October 30, 2009, we completed our acquisition of Allied Capital's interests in the Senior Secured Loan Fund for $165 million in cash and on December 29, 2009, we made an incremental investment in IHAM to facilitate its acquisition of Allied Capital's management rights in respect of, and interests in, Ivy Hill SDF for approximately $33 million in cash. On March 24, 2010, we made an incremental investment in IHAM to facilitate its acquisition of Allied Capital's management rights in respect of, and a portion of its interests in, the Knightsbridge Funds. We also acquired interests in the Knightsbridge Funds. Finally, on April 1, 2010, we consummated the Allied Acquisition, becoming the largest business development company measured by market capitalization and total portfolio companies under management as of June 30, 2010. For further discussion on these transactions, see "Management's Discussion and Analysis of Financial Condition and Results of Operations—Allied Acquisition" and "Business—Investments."

              We and our portfolio company IHAM have been and from time to time engage in discussions with counterparties in respect of various potential strategic acquisition and investment transactions, including potential acquisitions of other finance companies. Some of these transactions could be material to our business and, if consummated, could be difficult to integrate, result in increased leverage or dilution and/or subject us to unexpected liabilities. However, none of these discussions has progressed to the point where the consummation of any such transaction could be deemed to be probable or reasonably certain as of the date of this prospectus. Consummation of any such transaction will be subject to completion of due diligence, finalization of key business and financial terms (including price) and negotiation of final definitive documentation as well as a number of other factors and conditions including, without limitation, the approval of our board of directors (after having determined that such transaction is in the best interest of our stockholders), any required third party consents and, in certain cases, the approval of our stockholders. We cannot predict how quickly the terms of any such transaction could be finalized, if at all. Accordingly, there can be no assurance that

definitive documentation for any such transaction would be executed or even if executed, that any such transaction will be consummated. In connection with evaluating potential strategic acquisition and investment transactions, we have, and may in the future, incur significant expenses for the evaluation and due diligence investigation of these potential transactions.

LIQUIDITY

              We are party to a senior secured revolving credit facility (as amended and restated, the "Revolving Credit Facility") that provides for up to $810.0 million (and, to the extent we fully exercise the "accordion" feature of this facility, $1.05 billion) of borrowings. The Revolving Credit Facility expires on January 22, 2013.

              In addition, our wholly owned subsidiary Ares Capital CP Funding LLC ("Ares Capital CP") is party to a revolving facility (as amended, the "CP Funding Facility"), which, as amended, currently provides for up to $400.0 million of borrowings. The CP Funding Facility expires on January 22, 2013 (with two one year extension options, subject to mutual consent).

              We use the term "Facilities" to refer to the Revolving Credit Facility and the CP Funding Facility.

              In July 2006, through ARCC Commercial Loan Trust 2006 ("ARCC CLO"), we completed a $400.0 million debt securitization referred to herein as the "Debt Securitization" and issued approximately $314.0 million principal amount of asset-backed notes (including $50.0 million revolving notes, $27.0 million of which were drawn down as of September 30, 2010), which we refer to as the "CLO Notes," to third parties that are secured by a pool of middle market loans that were purchased or originated by the Company. We serve as the servicer to ARCC CLO. The CLO Notes mature on December 20, 2019.

              On April 1, 2010, as part of the Allied Acquisition, we assumed all of Allied Capital's outstanding debt obligations, including Allied Capital's publicly issued unsecured notes: the 6.625% Notes due on July 15, 2011 (the "2011 Notes"), the 6.000% Notes due on April 1, 2012 (the "2012 Notes") and the 6.875% Notes due on April 15, 2047 (the "2047 Notes" and, together with the 2011 Notes and the 2012 Notes, the "Unsecured Notes").

              As of September 30, 2010, we had $431.0 million outstanding under the Revolving Credit Facility and $283.4 million outstanding under the CP Funding Facility. As of September 30, 2010, we also had outstanding $177.2 million of CLO Notes that mature on December 20, 2019 and had outstanding $632.6 million (principal amount of $691.8 million) of Unsecured Notes as follows: $294.3 million (principal amount of $300.6 million) of 2011 Notes, $157.5 million (principal amount of $161.2 million) of 2012 Notes and $180.7 million (principal amount of $230.0 million) of 2047 Notes. See "Management's Discussion and Analysis of Financial Condition and Results of Operations—Financial Condition, Liquidity and Capital Resources."

OFFERINGS

              We may offer, from time to time, in one or more offerings or series, up to $1,500,000,000 of our common stock, preferred stock, debt securities, subscription rights to purchase shares of our common stock or warrants representing rights to purchase shares of our common stock, preferred stock or debt securities, or units comprised of any combination of the foregoing, 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. The offering price per share of our common stock, less any underwriting commissions or discounts, generally will not be less than the net asset value per share of our common stock at the time of an offering. However, we may issue shares of our common stock pursuant to this prospectus at a price per share that is less than our net asset value per share (a) in connection with a rights offering to our existing stockholders, (b) with the prior approval of the majority of our common stockholders or (c) under such other circumstances as the SEC may permit. Any such issuance of shares of our common stock below net asset value may be dilutive to the net asset value of our common stock. See "Risk Factors—Risks Relating to Offerings Pursuant to this Prospectus."

              At our 2010 Annual Stockholders Meeting, subject to certain determinations required to be made by our board of directors, our stockholders approved our ability to sell or otherwise issue shares of our common stock, not exceeding 25% of our then outstanding common stock, at a price below the then current net asset value per share during a period beginning on June 7, 2010 and expiring on the earlier of the one-year anniversary of the date of the 2010 Annual Stockholders Meeting and the date of our 2011 Annual Stockholders Meeting, which is expected to be held in May 2011.

              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

  Unless otherwise specified in a prospectus supplement, we intend to use the net proceeds from the sale of our securities for general corporate purposes, which includes, among other things, (a)  investing in portfolio companies in accordance with our investment objective and strategies and market conditions and (b) repaying indebtedness. Each supplement to this prospectus relating to an offering will more fully identify the use of the proceeds from such offering. See "Use of Proceeds."

Distributions

 

We intend to distribute quarterly dividends to our stockholders out of assets legally available for distribution. Our quarterly dividends, if any, will be determined by our board of directors. For more information, see "Price Range of Common Stock and Distributions."

Taxation

 

We have elected to be treated for U.S. federal income tax purposes as a RIC. As a RIC, we generally will not pay corporate-level U.S. federal income taxes on any income and gain that we distribute to our stockholders as dividends on a timely basis. Among other things, in order to maintain our RIC status, we must meet specified income source and asset diversification requirements and distribute annually generally an amount equal to at least 90% of our investment

company taxable income, out of assets legally available for distribution. See "Risk Factors—Risks Relating to Our Business—We may be subject to certain corporate-level taxes regardless of whether we continue to qualify as a RIC" and "Price Range of Common Stock and Distributions."

Dividend reinvestment plan

 

We have a dividend reinvestment plan for our stockholders. This is an "opt out" dividend reinvestment plan. As a result, if we declare a cash dividend, then stockholders' dividends 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. Stockholders whose cash dividends are reinvested in additional shares of our common stock will be subject to the same U.S. federal, state and local tax consequences as stockholders who elect to receive their dividends in cash. See "Dividend Reinvestment Plan."

Anti-takeover provisions

 

Our board of directors is divided into three classes of directors serving staggered three-year terms. This structure is intended to provide us with a greater likelihood of continuity of management, which may be necessary for us to realize the full value of our investments. A staggered board of directors also may serve to deter hostile takeovers or proxy contests, as may certain other measures adopted by us. See "Description of Our Capital Stock."

Leverage

 

We borrow funds to make additional investments. We use this practice, which is known as "leverage," to attempt to increase returns to our common stockholders, but it involves significant risks. See "Risk Factors," "Senior Securities" and "Regulation—Indebtedness and Senior Securities." With certain limited exceptions, we are only allowed to borrow amounts such that our asset coverage, as defined in the Investment Company Act, equals at least 200% after such borrowing. The amount of leverage that we employ at any particular time will depend on our investment adviser's and our board of directors' assessments of market and other factors at the time of any proposed borrowing.

Management arrangements

 

Ares Capital Management serves as our investment adviser. Ares Operations serves as our administrator. For a description of Ares Capital Management, Ares Operations, Ares and our contractual arrangements with these companies, see "Management—Investment Advisory and Management Agreement," and "—Administration Agreement."

Available information

 

We are required to file periodic reports, proxy statements and other information with the SEC. This information is available free of charge by calling us collect at (310) 201-4200 or on our website at www.arescapitalcorp.com. The SEC also maintains a website at www.sec.gov that contains this information.

Table of Contents

FEES AND EXPENSES

              The following table is intended to assist you in understanding the costs and expenses that an investor in our common stock will bear directly or indirectly, based on the assumptions set forth below. We caution you that some of the percentages indicated in the table below are estimates and may vary. Except where the context suggests otherwise, whenever this prospectus contains a reference to fees or expenses paid or to be paid by "you," "us," "the Company" or "Ares Capital," or that "we" will pay fees or expenses, stockholders will indirectly bear such fees or expenses as investors in Ares Capital.

Stockholder transaction expenses (as a percentage of offering price):

       

Sales load paid by us

        (1)

Offering expenses borne by us

        (2)

Dividend reinvestment plan expenses

(1)
In the event that the securities to which this prospectus relates are sold to or through underwriters, a corresponding prospectus supplement will disclose the applicable sales load (underwriting discount or commission). Purchases of shares of our common stock on the secondary market are not subject to sales charges but may be subject to brokerage commissions or other charges. The table does not include any sales load that stockholders may have paid in connection with their purchase of shares of our common stock.

(2)
The related prospectus supplement will disclose the estimated amount of offering expenses, the offering price and the offering expenses borne by us as a percentage of the offering price.

(3)
The expenses of the dividend reinvestment plan are included in "other expenses."

(4)
The related prospectus supplement will disclose the offering price and the total stockholder transaction expenses as a percentage of the offering price.

(5)
"Consolidated net assets attributable to common stock" equals our average net assets for the six months ending June 30, 2010. Because the Allied Acquisition was consummated on April 1, 2010 and because we calculate consolidated net assets attributable to common stock as a monthly average based on the period from January 1, 2010 to June 30, 2010, the consolidated net assets attributable to common stock used to calculate the amounts shown in this table are significantly lower than our net assets as of June 30, 2010.

(6)
Our management fee is currently 1.5% of our total assets other than cash and cash equivalents (which includes assets purchased with borrowed amounts). For the purposes of this table, we have assumed that we maintain no cash or cash equivalents. The 3.09% reflected on the table is calculated on our average net assets (rather than our total assets). See "Management—Investment Advisory and Management Agreement."

This item represents our investment adviser's incentive fees based on annualizing actual amounts earned on our pre-incentive fee net income for the six months ended June 30, 2010 and assumes that the incentive fees earned at the end of the 2010 calendar year will be based on the actual realized capital gains as of June 30, 2010, computed net of realized capital losses and unrealized capital depreciation. It also assumes that this fee will remain constant although it is based on Ares Capital's performance and will not be paid unless Ares Capital achieves certain goals. We expect to invest or otherwise utilize all of the net proceeds from securities registered under the registration statement of which this prospectus is a part pursuant to a particular prospectus supplement within three months of the date of the offering pursuant to such prospectus supplement and may have capital gains and interest income that could result in the payment of an incentive fee to our investment adviser in the first year after completion of offerings pursuant to this prospectus. Since our inception, the average quarterly incentive fee payable to our investment adviser has been approximately 0.63% of our weighted net assets (2.51% on an annualized basis). For more detailed information about incentive fees previously incurred by us, please see Note 3 to our consolidated financial statements for the period ended June 30, 2010.

The incentive fee consists of two parts:

The first, payable quarterly in arrears, equals 20% of our pre-incentive fee net investment income (including interest that is accrued but not yet received in cash), subject to a 2.00% quarterly (8% annualized) hurdle rate and a "catch-up" provision measured as of the end of each calendar quarter. Under this provision, in any calendar quarter, our investment adviser receives no incentive fee until our net investment income equals the hurdle rate of 2.00% 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 2.50%. The effect of this provision is that, if pre-incentive fee net investment income exceeds 2.50% in any calendar quarter, our investment adviser will receive 20% of our pre-incentive fee net investment income as if a hurdle rate did not apply.

The second part, payable annually in arrears, equals 20% of our realized capital gains on a cumulative basis from inception through the end of the year, if any, 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.

We will defer cash payment of any incentive fee otherwise earned by our investment adviser if, during the most recent four full calendar quarter period ending on or prior to the date such payment is to be made, the sum of (a) our aggregate distributions to our stockholders and (b) our change in net assets (defined as total assets less indebtedness and before taking into account any incentive fees payable during the period) is less than 8.0% of our net assets at the beginning of such period. These calculations will be adjusted for any share issuances or repurchases.

See "Management—Investment Advisory and Management Agreement."

(8)
"Interest payments on borrowed funds" represents an estimate of our annualized interest expense based on actual interest and credit facility expenses incurred for the six months ended June 30, 2010. During the six months ended June 30, 2010, our average borrowings were $1,512.5 million and cash paid for interest expense was $20.3 million. We had outstanding borrowings of $1,307.8 million (with a carrying value of $1,244.9 million) at June 30, 2010. This item is based on our assumption that our borrowings and interest costs after an offering will remain similar to those prior to such offering. The prospectus supplement related to the offering of any debt securities pursuant to this prospectus will calculate this item based on the effects of our borrowings and interest costs after the issuance of such debt securities. The amount of leverage that we employ at any particular time will depend on, among other things, our board of directors' and our investment adviser's assessment of market and other factors at the time of any proposed

Includes our overhead expenses, including payments under our administration agreement with Ares Operations based on our allocable portion of overhead and other expenses incurred by Ares Operations in performing its obligations under the administration agreement. Such expenses are estimated based on annualized "Other expenses" for the six months ended June 30, 2010 (other than $16.3 million of professional fees and other costs related to the Allied Acquisition, which are included in "Other expenses" but not annualized). See "Management—Administration Agreement." The holders of shares of our common stock (and not the holders of our debt securities or preferred stock, if any) indirectly bear the cost associated with our annual expenses.

(10)
The Company's stockholders indirectly bear the expenses of underlying investment companies in which the Company invests. This amount includes the fees and expenses of investment companies in which the Company is invested as of June 30, 2010. Certain of these investment companies are subject to management fees, which generally range from 1% to 2.5% of total net assets, or incentive fees, which generally range between 15% to 25% of net profits. When applicable, fees and expenses are based on historic fees and expenses for the investment companies. For those investment companies with little or no operating history, fees and expenses are based on expected fees and expenses stated in the investment companies' offering memorandum, private placement memorandum or other similar communication without giving effect to any performance. Future fees and expenses for these investment companies may be substantially higher or lower because certain fees and expenses are based on the performance of the investment companies, which may fluctuate over time. The amount of the Company's average net assets used in calculating this percentage was based on average monthly net assets of $2.0 billion for the six months ended June 30, 2010.

(11)
"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 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 before taking into account any incentive fees payable during the period), rather than the total assets, including assets that have been funded with borrowed monies.

Example

              The following example demonstrates the projected dollar amount of total cumulative expenses over various periods with respect to a hypothetical investment in our common stock. In calculating the following expense amounts, we have assumed that we would have no additional leverage, that none of our assets are cash or cash equivalents, and that our annual operating expenses would remain at the levels set forth in the table above. Transaction expenses are not included in the following example. In the event that shares to which this prospectus relates are sold to or through underwriters, a corresponding prospectus supplement will restate this example to reflect the applicable sales load.

 
  1 year   3 years   5 years   10 years  

You would pay the following expenses on a $1,000 investment, assuming a 5% annual return(1)

  $ 89   $ 257   $ 412   $ 749  

(1)
The above illustration assumes that we will not realize any capital gains computed net of all realized capital losses and unrealized capital depreciation. The expenses you would pay, based on a $1,000 investment and assuming a 5% annual return resulting entirely from net realized capital gains (and therefore subject to the capital gain incentive fee), and otherwise making the same

Table of Contents

              The foregoing table is to assist you in understanding the various costs and expenses that an investor in our common stock will bear directly or indirectly. While the example assumes, as required by the SEC, a 5% annual return, our performance will vary and may result in a return greater or less than 5%. The incentive fee under the investment advisory and management agreement, which, assuming a 5% annual return, would either not be payable or have an insignificant impact on the expense amounts shown above, is not included in the example. If we achieve sufficient returns on our investments, including through the realization of capital gains, to trigger an incentive fee of a material amount, our expenses, and returns to our investors, would be higher. In addition, while the example assumes reinvestment of all dividends and distributions at net asset value, if our board of directors authorizes and we declare a cash dividend, participants in our dividend reinvestment plan who have not otherwise elected to receive cash will receive a number of shares of our common stock, determined by dividing the total dollar amount of the dividend 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 dividend. See "Dividend Reinvestment Plan" for additional information regarding our dividend reinvestment plan.

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

RISK FACTORS

              Before you invest in our securities, you should be aware of various risks, including those described below. You should carefully consider these risk factors, together with all of the other information included in this prospectus including our consolidated financial statements and the related notes thereto, 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, the net asset value of our common stock and the trading price of our securities could decline, and you may lose all or part of your investment.

RISKS RELATING TO OUR BUSINESS

Capital markets have recently been in a period of disruption and instability. These market conditions have materially and adversely affected debt and equity capital markets in the United States, which has had, and may in the future have, a negative impact on our business and operations.

              Beginning in 2007, the U.S. capital markets entered into a period of disruption as evidenced by a lack of liquidity in the debt capital markets, significant write-offs in the financial services sector, the re-pricing of credit risk in the broadly syndicated credit market and the failure of major financial institutions. Despite actions of the U.S. federal government, these events contributed to worsening general economic conditions that materially and adversely impacted the broader financial and credit markets and reduced the availability of debt and equity capital for the market as a whole and financial services firms in particular. While these conditions have improved, there can be no assurance that they will not worsen in the future. If these adverse market conditions return, we and other companies in the financial services sector may have to access, if available, alternative markets for debt and equity capital in order to grow. Equity capital may be difficult to raise because, subject to some limited exceptions, as a BDC, we are generally not able to issue additional shares of our common stock at a price less than net asset value without first obtaining approval for such issuance from our stockholders and our independent directors. At our 2010 Annual Stockholders Meeting, subject to certain determinations required to be made by our board of directors, our stockholders approved our ability to sell or otherwise issue shares of our common stock, not exceeding 25% of our then outstanding common stock, at a price below the then current net asset value per share during a period beginning on June 7, 2010 and expiring on the earlier of the one-year anniversary of the date of the 2010 Annual Stockholders Meeting and the date of our 2011 Annual Stockholders Meeting, which is expected to be held in May 2011. In addition, our ability to incur indebtedness (including by issuing preferred stock) is limited by applicable regulations such that our asset coverage, as defined in the Investment Company Act, must equal at least 200% immediately after each time we incur indebtedness. The debt capital that will be available, if at all, may be at a higher cost and on less favorable terms and conditions in the future. Any inability to raise capital could have a negative effect on our business, financial condition and results of operations.

              Moreover, recent market conditions have made, and may in the future make, it difficult to extend the maturity of or refinance our existing indebtedness and any failure to do so could have a material adverse effect on our business. The illiquidity of our investments may make it difficult for us to sell such investments if required. As a result, we may realize significantly less than the value at which we have recorded our investments.

              Capital markets volatility also affects our investment valuations. While most of our investments are not publicly traded, applicable accounting standards require us to assume as part of our valuation process that our investments are sold in a principal market to market participants (even if we plan on holding an investment through its maturity). As a result, volatility in the capital markets can adversely affect our valuations.

25


Table of Contents

              Given the recent extreme volatility and dislocation in the capital markets, many BDCs have faced, and may in the future face, a challenging environment in which to raise capital. As a result of the recent significant changes in the capital markets affecting our ability to raise capital, the pace of our investment activity has slowed. In addition, significant changes in the capital markets, including the recent extreme volatility and disruption, has had, and may in the future have, a negative effect on the valuations of our investments and on the potential for liquidity events involving our investments. An inability to raise capital, and any required sale of our investments for liquidity purposes, could have a material adverse impact on our business, financial condition or results of operations.

A failure on our part to maintain our status as a BDC would significantly reduce our operating flexibility.

              If we fail to maintain our status as a BDC, we might be regulated as a closed-end investment company under the Investment Company Act, which would subject us to additional regulatory restrictions and significantly decrease our operating flexibility. In addition, any such failure could cause an event of default under our outstanding indebtedness, which could have a material adverse effect on our business, financial condition or results of operations.

We are dependent upon Ares Capital Management's key personnel for our future success and upon their access to Ares' investment professionals.

              We depend on the diligence, skill and network of business contacts of Ares Capital Management's key personnel, including its investment committee. We also depend, to a significant extent, on Ares Capital Management's access to the investment professionals of Ares and the information and deal flow generated by Ares' investment professionals in the course of their investment and portfolio management activities. Our future success depends on the continued service of Ares Capital Management's key personnel, including its investment committee. The departure of any of Ares Capital Management's key personnel, including members of its investment committee, or of a significant number of the investment professionals or partners of Ares, could have a material adverse effect on our business, financial condition or results of operations. In addition, we cannot assure you that Ares Capital Management will remain our investment adviser or that we will continue to have access to Ares' investment professionals or its information and deal flow.

Our financial condition and results of operations depend on our ability to manage future growth effectively.

              Our ability to achieve our investment objective depends on our ability to acquire suitable investments and monitor and administer those investments, which depends, in turn, on Ares Capital Management's ability to identify, invest in and monitor companies that meet our investment criteria.

              Accomplishing this result on a cost-effective basis is largely a function of Ares Capital Management's structuring of the investment process and its ability to provide competent, attentive and efficient services to us. Our executive officers and the members of Ares Capital Management's investment committee have substantial responsibilities in connection with their roles at Ares and with the other Ares funds, as well as responsibilities under the investment advisory and management agreement. They may also be called upon to provide significant managerial assistance to certain of our portfolio companies. These demands on their time, which will increase as the number of investments grow, may distract them or slow the rate of investment. In order to grow, Ares Capital Management will need to hire, train, supervise and manage new employees. However, we cannot assure you that any such employees will be retained. Any failure to manage our future growth effectively could have a material adverse effect on our business, financial condition and results of operations.

              In addition, as we grow, we may open up new offices in new geographic regions that may increase our direct operating expenses without corresponding revenue growth.

We may be unable to realize the benefits anticipated by the Allied Acquisition, including estimated cost savings and synergies, or it may take longer than anticipated to achieve such benefits.

              On April 1, 2010, we consummated the Allied Acquisition. The realization of certain benefits anticipated as a result of the Allied Acquisition will depend in part on the integration of Allied Capital's investment portfolio and business with our investment portfolio and business. There can be no assurance that Allied Capital's investment portfolio or business can be operated profitably or integrated successfully into our operations in a timely fashion, or at all. The dedication of management resources to such integration may detract attention from our day-to-day business, including new origination activity, and there can be no assurance that there will not be substantial costs associated with the transition process or other material adverse consequences to our business as a result of these integration efforts. Such effects, including, but not limited to, incurring unexpected costs or delays in connection with such integration and failure of Allied Capital's investment portfolio to perform as expected, could have a material adverse effect on our financial results.

              We anticipate achieving certain cost savings and synergies from the Allied Acquisition when the two companies have fully integrated their portfolios. It is possible, however, that our estimates of these potential cost savings and synergies could be incorrect. Allied Capital had significantly higher average borrowings and cash paid for interest expense for the three months ended March 31, 2010 and the year ended December 31, 2009, as compared to Ares Capital's borrowings and interest expense. Assuming such debt remained outstanding, the combined company's annual expenses as a percentage of consolidated net assets attributable to common stock is estimated to increase for Ares Capital stockholders on a pro forma combined basis. In addition, the cost savings and synergies estimates also assume our ability to pay down or refinance certain portions of Allied Capital's debt and to combine our investment portfolio and business with Allied Capital's investment portfolio and business in a manner that permits those cost savings and synergies to be fully realized. If the estimates turn out to be incorrect or we are not able to successfully refinance or pay down certain portions of Allied Capital's debt and combine the investment portfolios and businesses of the two companies, the anticipated cost savings and synergies may not be fully realized, or realized at all, or may take longer to realize than expected.

Our ability to grow depends on our ability to raise capital.

              We will need to periodically access the capital markets to raise cash to fund new investments. Ares has elected to be treated as a RIC and operates in a manner so as to qualify for the U.S. federal income tax treatment applicable to RICs. Among other things, in order to maintain our RIC status, we must distribute to our stockholders on a timely basis generally an amount equal to at least 90% of our investment company taxable income, and, as a result, such distributions will not be available to fund investment originations. We must continue to borrow from financial institutions and issue additional securities to fund our growth. Unfavorable economic or capital market conditions may increase our funding costs, limit our access to the capital markets or could result in a decision by lenders not to extend credit to us. An inability to successfully access the capital markets could limit our ability to grow our business and fully execute our business strategy and could decrease our earnings, if any.

              In addition, with certain limited exceptions, we are only allowed to borrow amounts or issue debt securities or preferred stock, which we refer to collectively as "senior securities," such that our asset coverage, as defined in the Investment Company Act, equals at least 200% immediately after such borrowing, which, in certain circumstances, may restrict our ability to borrow or issue debt securities or preferred stock. The amount of leverage that we employ will depend on our investment adviser's and our board of directors' assessments of market and other factors at the time of any proposed borrowing or issuance of debt securities or preferred stock. We cannot assure you that we will be able to maintain our current Facilities or obtain other lines of credit at all or on terms acceptable to us.

Regulations governing our operation as a BDC affect our ability to, and the way in which we, raise additional capital.

              We may issue senior securities or borrow money from banks or other financial institutions, up to the maximum amount permitted by the Investment Company Act. Under the provisions of the Investment Company Act, we are permitted, as a BDC, to incur indebtedness or issue senior securities only in amounts such that our asset coverage, as defined in the Investment Company Act, equals at least 200% after each such incurrence or issuance. If the value of our assets declines, we may be unable to satisfy this test, which may prohibit us from paying dividends and could prevent us from maintaining our status as a RIC or may prohibit us from repurchasing shares of our common stock. In addition, our inability to satisfy this test could cause an event of default under our existing indebtedness. If we cannot satisfy this test, we may be required to sell a portion of our investments at a time when such sales may be disadvantageous and, depending on the nature of our leverage, repay a portion of our indebtedness. Accordingly, any failure to satisfy this test could have a material adverse effect on our business, financial condition or results of operations. As of June 30, 2010, our asset coverage for senior securities was 318%.

              We are not generally able to issue and sell our common stock at a price below net asset value per share. We may, however, sell our common stock, or warrants, options or rights to acquire our common stock, at a price below the current net asset value per share of our common stock if our board of directors determines that such sale is in our best interests and the best interests of our stockholders, and our stockholders approve such sale. Any such sale would be dilutive to the net asset value per share of our common stock. In any such case, the price at which our securities are to be issued and sold may not be less than a price which, in the determination of our board of directors, closely approximates the market value of such securities (less any commission or discount). If our common stock trades at a discount to net asset value, this restriction could adversely affect our ability to raise capital.

              At our 2010 Annual Stockholders Meeting, subject to certain determinations required to be made by our board of directors, our stockholders approved our ability to sell or otherwise issue shares of our common stock, not exceeding 25% of our then outstanding common stock, at a price below the then current net asset value per share during a period beginning on June 7, 2010 and expiring on the earlier of the one-year anniversary of the date of the 2010 Annual Stockholders Meeting and the date of our 2011 Annual Stockholders Meeting, which is expected to be held in May 2011.

              To generate cash for funding new investments, we have also securitized, and may in the future seek to securitize, our loans. To securitize loans, we may create a separate, wholly owned subsidiary and contribute or sell a pool of loans to such subsidiary (or one of its subsidiaries). Such subsidiary may then sell equity, issue debt or sell interests in the pool of loans, on a limited-recourse basis, the payments on which are generally limited to the pool of loans and the proceeds therefrom. We may also retain a portion of the equity interests in the securitized pool of loans. Any retained equity would be exposed to losses on the related pool of loans before any of the related debt securities. An inability to successfully securitize our loan portfolio could limit our ability to grow our business and fully execute our business strategy. The securitization market is subject to changing market conditions (including the recent, unprecedented dislocation of the securitization and finance markets generally) and we may not be able to access this market when we would otherwise deem appropriate. Moreover, the successful securitization of our loan portfolio might expose us to losses as the residual loans in which we do not sell interests may be those that are riskier and more apt to generate losses. The Investment Company Act may also impose restrictions on the structure of any securitization.

We borrow money, which magnifies the potential for gain or loss on amounts invested and may increase the risk of investing with us.

              Borrowings, also known as leverage, magnify the potential for gain or loss on amounts invested and, therefore, increase the risks associated with investing in our securities. We currently borrow under our Facilities, and in the future, may borrow from or issue debt securities to banks, insurance companies, funds, institutional investors and other lenders and investors. Holders of such debt securities have fixed dollar claims on our consolidated assets that are superior to the claims of our common stockholders or any preferred stockholders. If the value of our consolidated assets increases, then leveraging would cause the net asset value per share of our common stock to increase more sharply than it would have had we not incurred leverage.

              Conversely, if the value of our consolidated assets decreases, leveraging would cause net asset value to decline more sharply than it otherwise would have had we not incurred leverage. Similarly, any increase in our consolidated income in excess of consolidated interest payable on the borrowed funds would cause our net income to increase more than it would without the leverage, while any decrease in our consolidated income would cause net income to decline more sharply than it would have had we not borrowed. Such a decline could negatively affect our ability to make common stock dividend payments. There can be no assurance that a leveraging strategy will be successful.

              As of June 30, 2010, we had $357.9 million of outstanding borrowings under our Facilities, $214.4 million in aggregate principal amount of CLO Notes and $735.5 million in aggregate principal amount of Unsecured Notes. In order for us to cover our annual interest payments on indebtedness, we must achieve annual returns on our June 30, 2010 total assets of at least 1.56%. The weighted average interest rate charged on our borrowings as of June 30, 2010 was 4.74%. We intend to continue borrowing under the Facilities in the future and we may increase the size of the Facilities or issue debt securities or other evidences of indebtedness (although there can be no assurance that we will be successful in doing so). Our ability to service our debt depends largely on our financial performance and is subject to prevailing economic conditions and competitive pressures. The amount of leverage that we employ at any particular time will depend on our investment adviser's and our board of directors' assessments of market and other factors at the time of any proposed borrowing.

              Our Facilities, the CLO Notes and the Unsecured Notes impose financial and operating covenants that restrict our business activities, including limitations that could hinder our ability to finance additional loans and investments or to make the distributions required to maintain our status as a RIC. A failure to renew our Facilities or to add new or replacement debt facilities could have a material adverse effect on our business, financial condition or results of operations.

              The following table illustrates the effect on return to a holder of our common stock of the leverage created by our use of borrowing at the weighted average interest rate of 4.74% as of June 30, 2010, together with (i) our total value of net assets as of June 30, 2010; (ii) $1.24 billion debt outstanding as of June 30, 2010 and (iii) hypothetical annual returns on our portfolio of minus 15 to plus 15 percent.

In addition to regulatory requirements that restrict our ability to raise capital, the Facilities, the CLO Notes and the Unsecured Notes contain various covenants which, if not complied with, could accelerate repayment under the Facilities, the CLO Notes and the Unsecured Notes, thereby materially and adversely affecting our liquidity, financial condition and results of operations.

              The agreements governing the Facilities, the CLO Notes and the Unsecured Notes require us to comply with certain financial and operational covenants. These covenants include:

              As of the date of this prospectus, we are in compliance with the covenants of the Facilities, the CLO Notes and the Unsecured Notes. However, our continued compliance with these covenants depends on many factors, some of which are beyond our control. For example, depending on the condition of the public debt and equity markets and pricing levels, net unrealized depreciation in our portfolio may increase in the future. Any such increase could result in our inability to comply with our obligation to restrict the level of indebtedness that we are able to incur in relation to the value of our assets or to maintain a minimum level of stockholders' equity.

              Accordingly, although we believe we will continue to be in compliance, there are no assurances that we will continue to comply with the covenants in the Facilities, the CLO Notes and the Unsecured Notes. Failure to comply with these covenants would result in a default under the Revolving Credit Facility, the CP Funding Facility, the CLO Notes or the Unsecured Notes, which, if we were unable to obtain a waiver from the lenders under the Revolving Credit Facility, the purchasers under the CP Funding Facility, the trustee or holders of the CLO Notes or the trustees or holders of the Unsecured Notes, respectively, could accelerate repayment under the Revolving Credit Facility, the CP Funding Facility, the CLO Notes or the Unsecured Notes, respectively, and thereby have a material adverse impact on our business, financial condition and results of operations.

Our credit ratings may change and as a result the cost and flexibility under our debt instruments may change.

              As of June 30, 2010, we had a long-term counterparty credit rating from Standard & Poor's Ratings Service of BBB, a long-term issuer default rating from Fitch Ratings of BBB and a long-term issuer rating from Moody's Investor Service of Ba1. Interest expense on our Revolving Credit Facility and the CP Funding Facility is based on a pricing grid that fluctuates depending on our credit ratings. There can be no assurance that our ratings will be maintained. If our ratings are downgraded, our cost of borrowing will increase.

              In addition, if the ratings of our CLO Notes are downgraded, our ability to engage in certain transactions in respect of the investments held in the Debt Securitization, among other things, may under certain circumstances be restricted and certain principal proceeds may under certain circumstances be required to be used to further reduce the outstanding principal balance of the CLO Notes. There can be no assurance that the CLO Notes ratings will be maintained.

              In addition, ratings agencies are required to make substantial changes to their ratings policies and practices as a result of the Dodd-Frank Wall Street Reform and Consumer Protection Act (the "Dodd-Frank Act"), which President Obama signed into law on July 21, 2010. There can be no assurance that such changes will not affect our ratings.

We operate in a highly competitive market for investment opportunities.

              A number of entities compete with us to make the types of investments that we make in middle market companies. We compete with other BDCs, public and private funds, commercial and investment banks, commercial financing companies, insurance companies, high yield investors, hedge funds, and, to the extent they provide an alternative form of financing, private equity funds. Many of our competitors are substantially larger and have considerably greater financial, technical and marketing resources than we do. Some competitors may have a lower cost of funds and access to funding sources that are not available to us. In addition, some of our competitors may have higher risk tolerances or different risk assessments, which could allow them to consider a wider variety of investments and establish more relationships than us. Furthermore, many of our competitors are not subject to the regulatory restrictions that the Investment Company Act imposes on us as a BDC and that the Code imposes on us as a RIC. We cannot assure you that the competitive pressures we face will not have a material adverse effect on our business, financial condition and results of operations. Also, as a result of this competition, we may not be able to pursue attractive investment opportunities from time to time.

              We do not seek to compete primarily based on the interest rates we offer and we believe that some of our competitors may make loans with interest rates that are comparable to or lower than the rates we offer. Rather, we compete with our competitors based on our existing investment platform, seasoned management team, experience and focus on middle market companies, disciplined investment philosophy, extensive industry focus and flexible transaction structuring. For a more detailed discussion of these competitive advantages, see "Business—Competitive Advantages."

              We may lose investment opportunities if we do not match our competitors' pricing, terms and structure. If we match our competitors' pricing, terms and structure, we may experience decreased net interest income and increased risk of credit loss. As a result of operating in such a competitive environment, we may make investments that are on better terms to our portfolio companies than what we may have originally anticipated, which may impact our return on these investments.

We may be subject to certain corporate-level taxes regardless of whether we continue to qualify as a RIC.

              We have elected to be treated as a RIC under Subchapter M of the Code and operate in a manner so as to qualify for the U.S. federal income tax treatment applicable to RICs. As a RIC, we generally will not pay corporate-level U.S. federal income taxes on our income and gain that we distribute to our stockholders as dividends on a timely basis. To qualify as a RIC, we must meet certain income source, asset diversification and annual distribution requirements. We may also be subject to certain U.S. federal excise taxes, as well as state, local and foreign taxes.

              The annual distribution requirement for a RIC is satisfied if we distribute to our stockholders on a timely basis generally an amount equal to at least 90% of our investment company taxable income for each year. Because we use debt financing, we are subject to certain asset coverage ratio requirements under the Investment Company Act and financial covenants under our indebtedness that could, under certain circumstances, restrict us from making distributions necessary to qualify as a RIC. If we are unable to obtain cash from other sources, we may fail to qualify as a RIC and, thus, may be subject to corporate-level income tax. In that event, the resulting corporate-level taxes could substantially reduce our net assets, the amount of income available for distribution and the amount of our distributions. Because we must make distributions to our stockholders as described above, such

31


Table of Contents


amounts, to the extent a stockholder is not participating in our dividend reinvestment plan, will not be available to fund investment originations. We will be subject to corporate-level U.S. federal income tax on any undistributed income and/or gain.

              To qualify as a RIC, we must also meet certain annual income source requirements at the end of each taxable year and asset diversification requirements at the end of each calendar quarter. Failure to meet these tests may result in our having to (a) dispose of certain investments quickly or (b) raise additional capital to prevent the loss of RIC status. Because most of our investments are in private companies and are generally illiquid, any such dispositions may be at disadvantageous prices and may result in losses. Also, the rules applicable to our qualification as a RIC are complex with many areas of uncertainty. Accordingly, no assurance can be given that we have qualified or will qualify as a RIC. If we fail to qualify as a RIC for any reason and become subject to regular "C" corporation income tax, the resulting corporate 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. See "Certain Material U.S. Federal Income Tax Considerations—Taxation as a RIC."

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

              For U.S. federal income tax purposes, we include in income certain amounts that we have not yet received in cash, such as original issue discount, which may arise if we receive warrants in connection with the making of a loan or possibly in other circumstances, or payment-in-kind interest, which represents contractual interest added to the loan balance and due at the end of the loan term. Such original issue discount or increases in loan balances are included in income before we receive any corresponding cash payments. We also may be required to include in income certain other amounts that we will not receive in cash, including, for example, non-cash income from payment-in-kind securities, deferred payment securities and hedging and foreign currency transactions.

              Since, in certain cases, we may recognize income before or without receiving cash representing such income, we may have difficulty meeting the U.S. federal income tax requirement to distribute generally an amount equal to at least 90% of our investment company taxable income to maintain our status as a RIC. Accordingly, we may have to sell some of our investments at times we would not consider advantageous, raise additional debt or equity capital or reduce new investment originations to meet these distribution requirements. If we are not able to obtain cash from other sources, we may fail to qualify as a RIC and thus be subject to additional corporate-level taxes. See "Certain Material U.S. Federal Income Tax Considerations—Taxation as a RIC."

              If a portfolio company defaults on a loan that is structured to provide accrued interest, it is possible that accrued interest previously used in the calculation of the incentive fee will become uncollectible. The investment adviser is not under any obligation to reimburse us for any part of the incentive fee it received that was based on accrued income that we never receive as a result of a default by an entity on the obligation that resulted in the accrual of such income.

We may in the future determine to fund a portion of our investments with preferred stock, which would magnify the potential for gain or loss and the risks of investing in us in the same way as our borrowings.

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

We are exposed to risks associated with changes in interest rates.

              General interest rate fluctuations may have a substantial negative impact on our investments and investment opportunities and, accordingly, may have a material adverse effect on our investment objective and rate of return on invested capital. Because we borrow money and may issue debt securities or preferred stock to make investments, our net investment income is dependent upon the difference between the rate at which we borrow funds or pay interest or dividends on such debt securities or preferred stock and the rate at which we invest these funds. 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. Trading prices for debt that pays a fixed rate of return tend to fall as interest rates rise. Trading prices tend to fluctuate more for fixed-rate securities that have longer maturities. We have entered into certain hedging transactions, such as interest rate swap agreements, to mitigate our exposure to adverse fluctuations in interest rates, and we may continue to do so in the future. However, we cannot assure you that such transactions will be successful in mitigating our exposure to credit risk. Hedging transactions may also limit our ability to participate in the benefits of lower interest rates with respect to our portfolio investments. Although we have no policy governing the maturities of our investments, under current market conditions we expect that we will invest in a portfolio of debt generally having maturities of up to 10 years. This means that we are subject to greater risk (other things being equal) than a fund invested solely in shorter-term securities. A decline in the prices of the debt we own could adversely affect the trading price of our shares. Also, an increase in interest rates available to investors could make investment in our common stock less attractive if we are not able to increase our dividend rate, which could reduce the value of our common stock.

Many of our portfolio investments are not publicly traded and, as a result, there is uncertainty as to the value of our portfolio investments.

              A large percentage of our portfolio investments are not publicly traded. The fair value of investments that are not publicly traded may not be readily determinable. We value these investments quarterly at fair value as determined in good faith by our board of directors based on the input of our management and audit committee and independent valuation firms that have been engaged at the direction of the board to assist in the valuation of each portfolio investment without a readily available market quotation at least once during a trailing 12-month period. The valuation process is conducted at the end of each fiscal quarter, with approximately 50% (based on value) of our valuations of portfolio companies without readily available market quotations subject to review by an independent valuation firm each quarter. However, we may use additional independent valuation firms to review our valuation of investments more frequently, including in connection with the occurrence of significant events or changes in value affecting a particular investment. The types of factors that may be considered in valuing our investments include the enterprise value of the portfolio company, the nature and realizable value of any collateral, the portfolio company's ability to make payments and its earnings, the markets in which the portfolio company does business, comparison to publicly traded companies, discounted cash flow and other relevant factors. Because such valuations, and particularly valuations of private investments and private companies, are inherently uncertain, may fluctuate over short periods of time and may be based on estimates, our determinations of fair value may differ materially from the values that would have been used if a ready market for these investments existed and may differ materially from the values that we may ultimately realize. Our net asset value per share could be adversely affected if our determinations regarding the fair value of these investments are materially higher than the values that we realize upon disposition of such investments.

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

              As we generally make investments in private companies, substantially all of these investments are subject to legal and other restrictions on resale or are otherwise less liquid than publicly traded securities. The illiquidity of our investments may make it difficult for us to sell such investments if the need arises. In addition, if we are required to liquidate all or a portion of our portfolio quickly, we may realize significantly less than the value at which we have recorded our investments. In addition, we may face other restrictions on our ability to liquidate an investment in a portfolio company to the extent that we or an affiliated manager of Ares has material non-public information regarding such portfolio company.

We may experience fluctuations in our quarterly results.

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

There are significant potential conflicts of interest that could impact our investment returns.

              Certain of our executive officers and directors, and members of the investment committee of our investment adviser, serve or may serve as officers, directors or principals of other entities and affiliates of our investment adviser and investment funds managed by our affiliates. Accordingly, they may have obligations to investors in those entities, the fulfillment of which might not be in our or our stockholders' best interests or that may require them to devote time to services for other entities, which could interfere with the time available to provide services to us. For example, Messrs. Ressler, Rosenthal, Kissick and Sachs each have significant responsibilities for other Ares funds. Messrs. Ressler and Rosenthal are required to devote a substantial majority of their business time, and Mr. Kissick is required to devote a majority of his business time, to the affairs of ACOF. However, Ares believes that the efforts of Messrs. Ressler, Rosenthal and Kissick relative to Ares Capital and ACOF are synergistic with and beneficial to the affairs of each of Ares Capital and ACOF.

              In addition, certain Ares funds may have investment objectives that compete or overlap with, and may from time to time invest in asset classes similar to those targeted by, Ares Capital. We may compete with these Ares funds or other investment vehicles managed by our investment adviser and its affiliates for capital and investment opportunities. Ares Capital Management endeavors to allocate investment opportunities in a fair and equitable manner, and in any event consistent with any fiduciary duties owed to Ares Capital. Nevertheless, it is possible that we may not be given the opportunity to participate in certain investments made by investment funds managed by investment managers affiliated with Ares Capital Management. In addition, there may be conflicts in the allocation of investment opportunities among us and the funds managed by us or one or more of our controlled affiliates, including IHAM, or among the funds they manage. We may or may not participate in investments made by funds managed by us or one or more of our controlled affiliates.

              We have from time to time sold assets to certain funds managed by IHAM and, as part of our investment strategy, we may offer to sell additional assets to funds managed by us and/or one or more of our controlled affiliates or we may purchase assets from funds managed by us, IHAM and/or one or more of our controlled affiliates. In addition, funds managed by us, IHAM or one or more of our controlled affiliates may offer assets to or may purchase assets from one another. While assets may be sold or purchased at prices that are consistent with those that could be obtained from third parties in the marketplace, and although these types of transactions generally require approval of one or more

34


Table of Contents


independent parties, there is an inherent conflict of interest in such transactions between us, IHAM and funds managed by us or one of our controlled affiliates.

              We pay management and incentive fees to Ares Capital Management, and reimburse Ares Capital Management for certain expenses it incurs. In addition, investors in our common stock will invest on a gross basis and receive distributions on a net basis after expenses, resulting in, among other things, a lower rate of return than one might achieve through direct investments.

              Ares Capital Management's management fee is based on a percentage of our total assets (other than cash or cash equivalents but including assets purchased with borrowed funds) and Ares Capital Management may have conflicts of interest in connection with decisions that could affect our total assets, such as decisions as to whether to incur indebtedness or to make future acquisitions.

              The part of the incentive fee payable by us that relates to our pre-incentive fee net investment income is computed and paid on income that may include interest that is accrued but not yet received in cash. If a portfolio company defaults on a loan that is structured to provide accrued interest, it is possible that accrued interest previously used in the calculation of the incentive fee will become uncollectible.

              Our investment advisory and management agreement renews for successive annual periods if approved by our board of directors or by the affirmative vote of the holders of a majority of our outstanding voting securities, including, in either case, approval by a majority of our directors who are not "interested persons" of the Company as defined in Section 2(a)(19) of the Investment Company Act. However, both we and Ares Capital Management have the right to terminate the agreement without penalty upon 60 days' written notice to the other party. Moreover, conflicts of interest may arise if our investment adviser seeks to change the terms of our investment advisory and management agreement, including, for example, the terms for compensation. While any material change to the investment advisory and management agreement must be submitted to stockholders for approval under the Investment Company Act, we may from time to time decide it is appropriate to seek stockholder approval to change the terms of the agreement.

              Pursuant to a separate amended and restated administration agreement, referred to herein as our "administration agreement," Ares Operations, an affiliate of Ares Capital Management, furnishes us with administrative services and we pay Ares Operations at cost our allocable portion of overhead and other expenses incurred by Ares Operations in performing its obligations under the administration agreement, including our allocable portion of the cost of our officers and their respective staffs.

              Our portfolio company, IHAM, is party to a separate administration agreement, referred to herein as the "IHAM administration agreement," with Ares Operations, pursuant to which Ares Operations provides IHAM with the facilities and administrative services necessary for the operations of IHAM. Under the IHAM administration agreement, IHAM reimburses Ares Operations for the costs associated with such services, including Ares Operations' allocable portion of overhead and the cost of its officers and respective staff in performing its obligations under the IHAM administration agreement. Prior to entering into the IHAM administration agreement, IHAM was party to a services agreement with Ares Capital Management, pursuant to which Ares Capital Management provided similar services.

              We rent office space directly from a third party pursuant to a lease that expires on February 27, 2011. In addition, we have entered into a sublease with Ares Management whereby Ares Management subleases approximately 25% of the office space for a fixed rent equal to 25% of the basic annual rent payable by us under this lease, plus certain additional costs and expenses. Further, IHAM reimburses us for a portion of our total rent, plus certain additional costs and expenses, which corresponds to the amount of office space used by IHAM. We recently entered into a new office lease pursuant to which we will lease new office facilities from a third party and start to pay rent on the new

35


Table of Contents


office space in the first quarter of 2011. We also entered into separate subleases with Ares Management and IHAM, pursuant to which Ares Management and IHAM will sublease approximately 15% and 20%, respectively, of the new office space, for a fixed rent equal to 15% and 20%, respectively, of the basic annual rent payable by us under the new office lease, plus certain additional costs and expenses.

              As a result of the arrangements described above, there may be times when the management teams of Ares Capital Management and Ares Management have interests that differ from those of our stockholders, giving rise to a conflict.

              Our stockholders may have conflicting investment, tax and other objectives with respect to their investments in us. The conflicting interests of individual stockholders may relate to or arise from, among other things, the nature of our investments, the structure or the acquisition of our investments, and the timing of disposition of our investments. As a consequence, conflicts of interest may arise in connection with decisions made by our investment adviser, including with respect to the nature or structuring of our investments, that may be more beneficial for one stockholder than for another stockholder, especially with respect to stockholders' individual tax situations. In selecting and structuring investments appropriate for us, our investment adviser will consider the investment and tax objectives of the Company and our stockholders, as a whole, not the investment, tax or other objectives of any stockholder individually.

Changes in laws or regulations governing our operations or the operations of our portfolio companies, changes in the interpretation thereof or newly enacted legislation and regulations, such as the Dodd-Frank Act, and any failure by us or our portfolio companies to comply with these laws or regulations, could require changes to certain business practices of us or our portfolio companies, negatively impact the operations, cash flows or financial condition of us or our portfolio companies, impose additional costs on us or our portfolio companies or otherwise adversely affect our business or the business of our portfolio companies.

              We and our portfolio companies are subject to regulation by laws at the local, state and federal levels. These laws and regulations, as well as their interpretation, may be changed from time to time, and new laws and regulations may be enacted. Accordingly, any change in these laws or regulations, changes in their interpretation, or newly enacted legislation or regulation, and any failure by us or our portfolio companies to comply with these laws or regulations, could require changes to certain business practices of us or our portfolio companies, negatively impact the operations, cash flows or financial condition of us or our portfolio companies, impose additional costs on us or our portfolio companies or otherwise adversely affect our business or the business of our portfolio companies.

              On July 21, 2010, President Obama signed into law the Dodd-Frank Act. Many of the provisions of the Dodd-Frank Act have extended implementation periods and delayed effective dates and will require extensive rulemaking by regulatory authorities. In particular, Title IV of the Dodd-Frank Act, the Private Fund Investment Advisers Registration Act of 2010 (the "Advisers Registration Act"), becomes effective one year after the date of enactment and eliminates the "private adviser exemption" from SEC registration currently contained in Section 203(b)(3) of the Advisers Act. This provision exempted from registration investment advisers who do not hold themselves out to the public as investment advisers and have fewer than 15 clients. As a result, many investment advisers to private funds (with some exceptions) will be required to register with the SEC and will become subject to substantial regulatory reporting and recordkeeping requirements regarding the private funds they advise.

              While the impact of the Dodd-Frank Act on us and our portfolio companies may not be known for an extended period of time, the Dodd-Frank Act, including future rules implementing its provisions and the interpretation of those rules, along with other legislative and regulatory proposals directed at

36


Table of Contents


the financial services industry or affecting taxation that are proposed or pending in the U.S. Congress, may negatively impact the operations, cash flows or financial condition of us or our portfolio companies, impose additional costs on us or our portfolio companies, intensify the regulatory supervision of us or our portfolio companies or otherwise adversely affect our business or the business of our portfolio companies. In particular, the Advisers Registration Act will likely require our wholly owned portfolio company, IHAM, to register as an investment adviser under the Advisers Act. This would require IHAM to comply with the regulatory restrictions and obligations imposed on registered investment advisers generally. In addition, as a BDC, we are currently restricted in our ability to invest in a registered investment adviser.

              We currently intend to seek relief from the SEC to enable us to continue to invest in IHAM; however, there can be no assurance that such relief will be granted. If we are not able to obtain relief, we may not be able to make future investments in IHAM, which could harm IHAM's business and the performance of our investments in IHAM.

Our investment adviser's liability is limited under the investment advisory and management agreement, and we are required to indemnify our investment adviser against certain liabilities, which may lead our investment adviser to act in a riskier manner on our behalf than it would when acting for its own account.

              Our investment adviser has not assumed any responsibility to us other than to render the services described in the investment advisory and management agreement, and it will not be responsible for any action of our board of directors in declining to follow our investment adviser's advice or recommendations. Pursuant to the investment advisory and management agreement, our investment adviser and its managing members, officers and employees will not be liable to us for their acts under the investment advisory and management agreement, absent willful misfeasance, bad faith, gross negligence or reckless disregard in the performance of their duties. We have agreed to indemnify, defend and protect our investment adviser and its managing members, officers and employees with respect to all damages, liabilities, costs and expenses resulting from acts of our investment adviser not arising out of willful misfeasance, bad faith, gross negligence or reckless disregard in the performance of their duties under the investment advisory and management agreement. These protections may lead our investment adviser to act in a riskier manner when acting on our behalf than it would when acting for its own account. See "Risk Factors—Risks Relating to Our Investments—Our investment adviser's incentive fee may induce Ares Capital Management to make certain investments, including speculative investments."

We may be obligated to pay our investment adviser incentive compensation even if we incur a loss.

              Our investment adviser is entitled to incentive compensation for each fiscal quarter in an amount equal to a percentage of the excess of our pre-incentive fee net investment income for that quarter (before deducting incentive compensation, net operating losses and certain other items) above a threshold return for that quarter. Our pre-incentive fee net investment income for incentive compensation purposes excludes realized and unrealized capital losses or depreciation that we may incur in the fiscal quarter, even if such capital losses or depreciation result in a net loss on our statement of operations for that quarter. Thus, we may be required to pay our manager incentive compensation for a fiscal quarter even if there is a decline in the value of our portfolio or we incur a net loss for that quarter.

              Under the investment advisory and management agreement, we will defer cash payment of any incentive fee otherwise earned by our investment adviser if, during the most recent four full calendar quarter periods ending on or prior to the date such payment is to be made, the sum of (a) our aggregate distributions to our stockholders and (b) our change in net assets (defined as total assets less indebtedness and before taking into account any incentive fees payable during the period) is less than

Table of Contents


8.0% of our net assets at the beginning of such period. These calculations will be adjusted for any share issuances or repurchases. Any deferred incentive fees will be carried over for payment in subsequent calculation periods to the extent such payment can then be made under the investment advisory and management agreement.

We may not replicate Ares' historical success and our ability to enter into transactions with Ares and our other affiliates is restricted.

              Investors in Ares Capital are not acquiring an interest in other Ares managed funds. Accordingly, we cannot assure you that Ares Capital will replicate Ares' historical success, and we caution you that our investment returns could be substantially lower than the returns achieved by those funds.

              Further, we and certain of our controlled affiliates are prohibited under the Investment Company Act from knowingly participating in certain transactions with our upstream affiliates, our investment adviser and its affiliates without the prior approval of our independent directors and, in some cases, the SEC. Any person that owns, directly or indirectly, 5% or more of our outstanding voting securities is our upstream affiliate for purposes of the Investment Company Act and we are generally prohibited from buying or selling any security (other than our securities) from or to such affiliate, absent the prior approval of our independent directors. The Investment Company Act also prohibits "joint" transactions with an upstream affiliate, or our investment adviser or its affiliates, which could include investments in the same portfolio company (whether at the same or different times), without prior approval of our independent directors. In addition, we and certain of our controlled affiliates are prohibited from buying or selling any security from or to, or entering into joint transactions with, our investment adviser and its affiliates, or any person who owns more than 25% of our voting securities or is otherwise deemed to control, be controlled by, or be under common control with us, absent the prior approval of the SEC through an exemptive order (other than in certain limited situations pursuant to current regulatory guidance). The analysis of whether a particular transaction constitutes a joint transaction requires a review of the relevant facts and circumstances then existing.

              We have applied for an exemptive order from the SEC that would permit us and certain of our controlled affiliates to co-invest with funds managed by Ares. Any such order will be subject to certain terms and conditions and there can be no assurance that such order will be granted by the SEC. Accordingly, we cannot assure you that we or our controlled affiliates will be permitted to co-invest with funds managed by Ares, other than in the limited circumstances currently permitted by regulatory guidance or in the absence of a joint transaction.

RISKS RELATING TO OUR INVESTMENTS

Price declines and illiquidity in the corporate debt markets have adversely affected, and may in the future adversely affect, the fair value of our portfolio investments, reducing our net asset value through increased net unrealized depreciation.

              As a BDC, we are required to carry our investments at market value or, if no market value is ascertainable, at fair value as determined in good faith by or under the direction of our board of directors. We may take into account the following types of factors, if relevant, in determining the fair value of our investments: the enterprise value of a portfolio company (an estimate of the total fair value of the portfolio company's debt and equity), 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, a comparison of the portfolio company's securities to publicly traded securities, changes in the interest rate environment and the credit markets generally that may affect the price at which similar investments may be made in the future and other relevant factors. When an external event such as a purchase transaction, public offering or subsequent equity

38


Table of Contents


sale occurs, we use the pricing indicated by the external event to corroborate our valuation. Decreases in the market values or fair values of our investments are recorded as unrealized depreciation. Unprecedented declines in prices and liquidity in the corporate debt markets resulted in significant net unrealized depreciation in our portfolio in the recent past. The effect of all of these factors on our portfolio has reduced our net asset value by increasing net unrealized depreciation in our portfolio. Depending on market conditions, we could incur substantial realized losses and may suffer additional unrealized losses in future periods, which could have a material adverse impact on our business, financial condition and results of operations.

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

              As of the date of this prospectus, the economy recently has been in the midst of a recession and in the difficult part of a credit cycle with industry defaults increasing. Many of our portfolio companies may be materially and adversely affected by the credit cycle and, in turn, may be unable to satisfy their financial obligations (including their loans to us) over the coming months.

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

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

Investments in privately held middle market companies involve significant risks.

              We primarily invest in privately held U.S. middle market companies. Investments in privately held middle market companies involve a number of significant risks, including the following:

39


Table of Contents

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

              The debt that we invest in is typically not initially rated by any rating agency, but we believe that if such investments were rated, they would be below investment grade (rated lower than "Baa3" by Moody's Investors Service, lower than "BBB-" by Fitch Ratings or lower than "BBB-" by Standard & Poor's). Indebtedness of below investment grade quality is regarded as having predominantly speculative characteristics with respect to the issuer's capacity to pay interest and repay principal. Our mezzanine investments may result in an above average amount of risk and volatility or loss of principal. We also invest in assets other than mezzanine investments, including first and second lien loans, high-yield securities, U.S. government securities, credit derivatives and other structured securities and certain direct equity investments. These investments will entail additional risks that could adversely affect our investment returns. In addition, to the extent interest payments associated with such debt are deferred, such debt will be subject to greater fluctuations in value based on changes in interest rates. Also, such debt could subject us to phantom income, and since we generally do not receive any cash prior to maturity of the debt, the investment is of greater risk.

Investments in equity securities involve a substantial degree of risk.

              We may purchase common and other equity securities. Although common stocks have historically generated higher average total returns than fixed income securities over the long term, common stocks also have experienced significantly more volatility in those returns and in recent years have significantly under performed relative to fixed income securities. The equity securities we acquire may fail to appreciate and may decline in value or become worthless and our ability to recover our investment will depend on our portfolio company's success. Investments in equity securities involve a number of significant risks, including:

40


Table of Contents

              There are special risks associated with investing in preferred securities, including:

              Additionally, when we invest in first and second lien senior loans or mezzanine debt, we may acquire warrants or other equity securities as well. Our goal is ultimately to dispose of such equity interests and realize gains upon our disposition of such interests. However, the equity interests we receive may not appreciate in value and, in fact, may decline in value. Accordingly, we may not be able to realize gains from our equity interests, and any gains that we do realize on the disposition of any equity interests may not be sufficient to offset any other losses we experience.

              We may invest, to the extent permitted by law, in the equity securities of investment funds that are operating pursuant to certain exceptions to the Investment Company Act and in advisers to similar investment funds, and, to the extent we so invest, will bear our ratable share of any such company's expenses, including management and performance fees. We will also remain obligated to pay management and incentive fees to Ares Capital Management with respect to the assets invested in the securities and instruments of such companies. With respect to each of these investments, each of our common stockholders will bear his or her share of the management and incentive fee of Ares Capital Management as well as indirectly bearing the management and performance fees and other expenses of any such investment funds or advisers.

              Also, as a result of the Allied Acquisition, Allied Capital's equity investments, including equity investments larger than those we have traditionally made and equity investments pursuant to which Allied Capital controlled a particular portfolio company, became part of our portfolio. We intend to actively seek opportunities over time to dispose of certain of these investments and rotate them into higher-yielding first and second lien senior loans and mezzanine debt investments. However, there can be no assurance that this strategy will be successful.

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

              If one of our portfolio companies were to go bankrupt, even though we may have structured our interest as senior debt, depending on the facts and circumstances, a bankruptcy court might recharacterize our debt holding as an equity investment and subordinate all or a portion of our claim to that of other creditors. In addition, lenders can be subject to lender liability claims for actions taken by them where they become too involved in the borrower's business or exercise control over the borrower. For example, we could become subject to a lender's liability claim, if, among other things, we actually render significant managerial assistance.

Table of Contents


Our portfolio companies may incur debt or issue equity securities that rank equally with, or senior to, our investments in such companies.

              Our portfolio companies may have, or may be permitted to incur, other debt, or issue other equity securities, that rank equally with, or senior to, our investments. By their terms, such instruments may provide that the holders are entitled to receive payment of dividends, interest or principal on or before the dates on which we are entitled to receive payments in respect of our investments. These debt instruments usually prohibit the portfolio companies from paying interest on or repaying our investments in the event and during the continuance of a default under such debt. Also, in the event of insolvency, liquidation, dissolution, reorganization or bankruptcy of a portfolio company, holders of securities ranking senior to our investment in that portfolio company typically are entitled to receive payment in full before we receive any distribution in respect of our investment. After repaying such holders, the portfolio company may not have any remaining assets to use for repaying its obligation to us. In the case of securities ranking equally with our investments, we would have to share on an equal basis any distributions with other security holders in the event of an insolvency, liquidation, dissolution, reorganization or bankruptcy of the relevant portfolio company.

              The rights we may have with respect to the collateral securing any junior priority loans we make to our portfolio companies may also be limited pursuant to the terms of one or more intercreditor agreements that we enter into with the holders of senior debt. Under such an intercreditor agreement, at any time that senior obligations are outstanding, we may forfeit certain rights with respect to the collateral to the holders of the senior obligations. These rights may include the right to commence enforcement proceedings against the collateral, the right to control the conduct of such enforcement proceedings, the right to approve amendments to collateral documents, the right to release liens on the collateral and the right to waive past defaults under collateral documents. We may not have the ability to control or direct such actions, even if as a result our rights as junior lenders are adversely affected.

When we are a debt or minority equity investor in a portfolio company, we may not be in a position to exert influence on the entity, and management of the company may make decisions that could decrease the value of our portfolio holdings.

              We make both debt and minority equity investments; therefore, we are subject to the risk that a portfolio company may make business decisions with which we disagree, and the stockholders and management of such company may take risks or otherwise act in ways that do not serve our interests. As a result, a portfolio company may make decisions that could decrease the value of our investment.

Our portfolio companies may be highly leveraged.

              Some of our portfolio companies may be highly leveraged, which may have adverse consequences to these companies and to us as an investor. These companies may be subject to restrictive financial and operating covenants and the leverage may impair these companies' ability to finance their future operations and capital needs. As a result, these companies' flexibility to respond to changing business and economic conditions and to take advantage of business opportunities may be limited. Further, a leveraged company's income and net assets will tend to increase or decrease at a greater rate than if borrowed money were not used.

Our investment adviser's incentive fee may induce Ares Capital Management to make certain investments, including speculative investments.

              The incentive fee payable by us to Ares Capital Management may create an incentive for Ares Capital Management to make investments on our behalf that are risky or more speculative than would be the case in the absence of such compensation arrangement. The way in which the incentive fee

42


Table of Contents


payable to our investment adviser is determined, which is calculated as a percentage of the return on invested capital, may encourage our investment adviser to use leverage to increase the return on our investments. Under certain circumstances, the use of leverage may increase the likelihood of default, which would disfavor the holders of our common stock, including investors in offerings of common stock, securities convertible into our common stock or warrants representing rights to purchase our common stock or securities convertible into our common stock pursuant to this prospectus. In addition, the investment adviser will receive the incentive fee based, in part, upon net capital gains realized on our investments. Unlike the portion of the incentive fee based on income, there is no hurdle rate applicable to the portion of the incentive fee based on net capital gains. As a result, the investment adviser may have a tendency to invest more in investments that are likely to result in capital gains as compared to income producing securities. Such a practice could result in our investing in more speculative securities than would otherwise be the case, which could result in higher investment losses, particularly during economic downturns. The part of the incentive fee payable by us that relates to our pre-incentive fee net investment income will be computed and paid on income that may include interest that is accrued but not yet received in cash. If a portfolio company defaults on a loan that is structured to provide accrued interest, it is possible that accrued interest previously used in the calculation of the incentive fee will become uncollectible. The investment adviser is not under any obligation to reimburse us for any part of the incentive fee it received that was based on such accrued interest that we never actually receive.

              Because of the structure of the incentive fee, it is possible that we may have to pay an incentive fee in a quarter where we incur a loss. For example, if we receive pre-incentive fee net investment income in excess of the hurdle rate for a quarter, we will pay the applicable incentive fee even if we have incurred a loss in that quarter due to realized capital losses. In addition, if market interest rates rise, we may be able to invest our funds in debt instruments that provide for a higher return, which would increase our pre-incentive fee net investment income and make it easier for our investment adviser to surpass the fixed hurdle rate and receive an incentive fee based on such net investment income.

Our investments in foreign debt may involve significant risks in addition to the risks inherent in U.S. investments. We may expose ourselves to risks if we engage in hedging transactions.

              Our investment strategy contemplates potential investments in debt of foreign companies. Investing in foreign companies may expose us to additional risks not typically associated with investing in U.S. companies. These risks include changes in exchange control regulations, political and social instability, expropriation, imposition of foreign taxes (potentially at confiscatory levels), less liquid markets, less available information than is generally the case in the United States, higher transaction costs, less government supervision of exchanges, brokers and issuers, less developed bankruptcy laws, difficulty in enforcing contractual obligations, lack of uniform accounting and auditing standards and greater price volatility.

              Although most of our investments will be U.S. dollar denominated, our investments that are denominated in a foreign currency will be subject to the risk that the value of a particular currency will change in relation to one or more other currencies. Among the factors that may affect currency values are trade balances, the level of short-term interest rates, differences in relative values of similar assets in different currencies, long-term opportunities for investment and capital appreciation, and political developments. We may employ hedging techniques to minimize these risks, but we cannot assure you that such strategies will be effective.

              We have and may in the future enter into hedging transactions, which may expose us to risks associated with such transactions. We may utilize instruments such as forward contracts, currency options and interest rate swaps, caps, collars and floors to seek to hedge against fluctuations in the relative values of our portfolio positions from changes in currency exchange rates and market interest

43


Table of Contents


rates. Use of these hedging instruments may include counter party credit risk. Hedging against a decline in the values of our portfolio positions does not eliminate the possibility of fluctuations in the values of such positions or prevent losses if the values of such positions decline. However, such hedging can establish other positions designed to gain from those same developments, thereby offsetting the decline in the value of such portfolio positions. Such hedging transactions may also limit the opportunity for gain if the values of the underlying portfolio positions should increase. Moreover, it may not be possible to hedge against an exchange rate or interest rate fluctuation that is so generally anticipated that we are not able to enter into a hedging transaction at an acceptable price.

              The success of our hedging transactions will depend on our ability to correctly predict movements, currencies and interest rates. Therefore, while we may enter into such transactions to seek to reduce currency exchange rate and interest rate risks, unanticipated changes in currency exchange rates or interest rates may result in poorer overall investment performance than if we had not engaged in any such hedging transactions. In addition, the degree of correlation between price movements of the instruments used in a hedging strategy and price movements in the portfolio positions being hedged may vary. Moreover, for a variety of reasons, we may not seek to establish a perfect correlation between such hedging instruments and the portfolio holdings being hedged. Any such imperfect correlation may prevent us from achieving the intended hedge and expose us to risk of loss. In addition, it may not be possible to hedge fully or perfectly against currency fluctuations affecting the value of securities denominated in non-U.S. currencies because the value of those securities is likely to fluctuate as a result of factors not related to currency fluctuations. See also "Risk Factors—Risk Relating to our Business—We are exposed to risks associated with changes in interest rates."

We may initially invest a portion of the net proceeds of offerings pursuant to this prospectus primarily in high-quality short-term investments, which will generate lower rates of return than those expected from the interest generated on first and second lien loans and mezzanine debt.

              We may initially invest a portion of the net proceeds of offerings primarily in cash, cash equivalents, U.S. government securities and other high-quality short-term investments. These securities may earn yields substantially lower than the income that we anticipate receiving once we are fully invested in accordance with our investment objective. As a result, we may not be able to achieve our investment objective and/or pay any dividends during this period or, if we are able to do so, such dividends may be substantially lower than the dividends that we expect to pay when our portfolio is fully invested. If we do not realize yields in excess of our expenses, we may incur operating losses and the market price of our shares may decline.

The Allied Acquisition may have triggered certain "change of control" provisions and other restrictions in certain of our and Allied Capital's contracts and the failure to obtain any required consents or waivers could adversely impact us.

              Certain agreements of Allied Capital and Ares Capital or their controlled affiliates, including with respect to certain managed funds of Allied Capital and its affiliates, may have required the consent of one or more counterparties in connection with the Allied Acquisition. The failure to obtain any such consent may permit such counter-parties to terminate, or otherwise increase their rights or our or Allied Capital's obligations under, any such agreement because the Allied Acquisition may have violated an anti-assignment, change of control or similar provision. If this happens, we may have to seek to replace that agreement with a new agreement or seek a waiver or amendment to such agreement. We cannot assure you that we will be able to replace, amend or obtain a waiver under any such agreement on comparable terms or at all.

              If any such agreement is material, the failure to obtain consents, amendments or waivers under, or to replace on similar terms or at all, any of these agreements could adversely affect the

44


Table of Contents


financial performance or results of operations of the Company, including preventing us from operating a material part of Allied Capital's business.

              In addition, the Allied Acquisition may have violated, conflicted with, resulted in a breach of any provision of or the loss of any benefit under, constituted a default (or an event that, with or without notice or lapse of time or both, would constitute a default) under, or resulted in the termination, cancellation, acceleration or other change of any right or obligation (including any payment obligation) under our or Allied Capital's agreements. Any such violation, conflict, breach, loss, default or other effect could, if material, either individually or in the aggregate, adversely affect our business.

RISKS RELATING TO OFFERINGS PURSUANT TO THIS PROSPECTUS

Our shares of common stock have traded at a discount from net asset value and may do so again in the future, which could limit our ability to raise additional equity capital.

              Shares of closed-end investment companies frequently trade at a market price that is less than the net asset value that is attributable to those shares. This characteristic of closed-end investment companies is separate and distinct from the risk that our net asset value per share may decline. It is not possible to predict whether any shares of common stock offered hereby will trade at, above, or below net asset value. During much of 2009, the stocks of BDCs as an industry, including at times shares of our common stock, traded below net asset value and at near historic lows as a result of concerns over liquidity, leverage restrictions and distribution requirements. When our common stock is trading below its net asset value per share, we will generally not be able to issue additional shares of our common stock at its market price without first obtaining approval for such issuance from our stockholders and our independent directors.

There is a risk that investors in our equity securities may not receive dividends or that our dividends may not grow over time and that investors in our debt securities may not receive all of the interest income to which they are entitled.

              We intend to make distributions on a quarterly basis to our stockholders out of assets legally available for distribution. We cannot assure you that we will achieve investment results that will allow us to make a specified level of cash distributions or year-to-year increases in cash distributions. If we declare a dividend and if more stockholders opt to receive cash distributions rather than participate in our dividend reinvestment plan, we may be forced to sell some of our investments in order to make cash dividend payments.

              In addition, due to the asset coverage test applicable to us as a BDC, we may be limited in our ability to make distributions. Further, if we invest a greater amount of assets in equity securities that do not pay current dividends, it could reduce the amount available for distribution. See "Price Range of Common Stock and Distributions."

              The above referenced restrictions on distributions may also inhibit our ability to make required interest payments to holders of our debt securities, which may cause a default under the terms of our debt securities. Such a default could materially increase our cost of raising capital, as well as cause us to incur penalties under the terms of our debt securities.

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

              The Maryland General Corporation Law, our charter and our bylaws contain provisions that may discourage, delay or make more difficult a change in control of Ares Capital or the removal of our directors. We are subject to the Maryland Business Combination Act, subject to any applicable

45


Table of Contents


requirements of the Investment Company Act. Our board of directors has adopted a resolution exempting from the Business Combination Act any business combination between us and any other person, subject to prior approval of such business combination by our board, including approval by a majority of our disinterested directors. If the resolution exempting business combinations is repealed or our board does not approve a business combination, the Business Combination Act may discourage third parties from trying to acquire control of us and increase the difficulty of consummating such an offer. Our bylaws exempt from the Maryland Control Share Acquisition Act acquisitions of our stock by any person. If we amend our bylaws to repeal the exemption from the Control Share Acquisition Act, the Control Share Acquisition Act also may make it more difficult for a third party to obtain control of us and increase the difficulty of consummating such an offer.

              We have also adopted measures that may make it difficult for a third party to obtain control of us, including provisions of our charter classifying our board of directors in three classes serving staggered three-year terms, and provisions of our charter authorizing our board of directors to classify or reclassify shares of our stock in one or more classes or series, to cause the issuance of additional shares of our stock, and to amend our charter, without stockholder approval, to increase or decrease the number of shares of stock that we have authority to issue. These provisions, as well as other provisions of our charter and bylaws, may delay, defer or prevent a transaction or a change in control that might otherwise be in the best interests of our stockholders.

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

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

The market price of our common stock may fluctuate significantly.

              The capital and credit markets have experienced a period of extreme volatility and disruption that began in 2007. The market price and liquidity of the market for shares of our common stock may be significantly affected by numerous factors, some of which are beyond our control and may not be directly related to our operating performance. These factors include:

46


Table of Contents

              In the past, following periods of volatility in the market price of a company's securities, securities class action litigation has often been brought against that company. If our stock price fluctuates significantly, we may be the target of securities litigation in the future. Securities litigation could result in substantial costs and divert management's attention and resources from our business.

The net asset value per share of our common stock may be diluted if we sell shares of our common stock in one or more offerings at prices below the then current net asset value per share of our common stock or securities to subscribe for or convertible into shares of our common stock.

              At our 2010 Annual Stockholders Meeting, subject to certain determinations required to be made by our board of directors, our stockholders approved our ability to sell or otherwise issue shares of our common stock, not exceeding 25% of our then outstanding common stock, at a price below the then current net asset value per share during a period beginning on June 7, 2010 and expiring on the earlier of the one-year anniversary of the date of the 2010 Annual Stockholders Meeting and the date of our 2011 Annual Stockholders Meeting, which is expected to be held in May 2011.

              In addition, at our 2009 Annual Stockholders Meeting, our stockholders approved a proposal authorizing us to sell or otherwise issue warrants or securities to subscribe for or convertible into shares of our common stock subject to certain limitations (including, without limitation, that the number of shares issuable does not exceed 25% of our then outstanding common stock and that the exercise or conversion price thereof is not, at the date of issuance, less than the greater of the market value per share and the net asset value per share of our common stock). The authorization granted to sell or authorize issue warrants or securities to subscribe for or convertible into shares of our common stock has no expiration.

              Any decision to sell shares of our common stock below its then current net asset value per share or securities to subscribe for or convertible into shares of our common stock would be subject to the determination by our board of directors that such issuance is in our and our stockholders' best interests.

              If we were to sell shares of our common stock below its then current net asset value per share, such sales would result in an immediate dilution to the net asset value per share of our common stock. This dilution would occur as a result of the sale of shares at a price below the then current net asset value per share of our common stock and a proportionately greater decrease in the stockholders' interest in our earnings and assets and their voting interest in us than the increase in our assets resulting from such issuance. Because the number of shares of common stock that could be so issued and the timing of any issuance is not currently known, the actual dilutive effect cannot be predicted.

              In addition, if we issue warrants or securities to subscribe for or convertible into shares of our common stock, subject to certain limitations, the exercise or conversion price per share could be less than net asset value per share at the time of exercise or conversion (including through the operation of anti-dilution protections). Because we would incur expenses in connection with any issuance of such securities, such issuance could result in a dilution of the net asset value per share at the time of exercise or conversion. This dilution would include reduction in net asset value per share as a result of the proportionately greater decrease in the stockholders' interest in our earnings and assets and their voting interest than the increase in our assets resulting from such issuance.

              Further, if current stockholders of the Company do not purchase any shares to maintain their percentage interest, regardless of whether such offering is above or below the then current net asset value per share, their voting power will be diluted. For additional information and hypothetical

47


Table of Contents


examples of these risks, see "Sales of Common Stock Below Net Asset Value" and the prospectus supplement pursuant to which such sale is made.

Your interest in us may be diluted if you do not fully exercise your subscription rights in any rights offering. In addition, if the subscription price is less than our net asset value per share, then you will experience an immediate dilution of the aggregate net asset value of your shares.

              In the event we issue subscription rights, stockholders who do not fully exercise their subscription rights should expect that they will, at the completion of a rights offering pursuant to this prospectus, own a smaller proportional interest in us than would otherwise be the case if they fully exercised their rights. We cannot state precisely the amount of any such dilution in share ownership because we do not know at this time what proportion of the shares will be purchased as a result of such rights offering.

              In addition, if the subscription price is less than the net asset value per share of our common stock, then our stockholders would experience an immediate dilution of the aggregate net asset value of their shares as a result of the offering. The amount of any decrease in net asset value is not predictable because it is not known at this time what the subscription price and net asset value per share will be on the expiration date of a rights offering or what proportion of the shares will be purchased as a result of such rights offering. Such dilution could be substantial. See "Risk Factors—Risks Relating to Offerings Pursuant to this Prospectus—The net asset value per share of our common stock and our stockholders' voting interests in us may be diluted if we sell shares of our common stock in one or more offerings at prices below the then current net asset value per share of our common stock or securities to subscribe for or convertible into shares of our common stock" and "Sales of Common Stock Below Net Asset Value."

Investors in offerings of our common stock will likely incur immediate dilution upon the closing of such offering.

              We generally expect the public offering price of any offering of shares of our common stock to be higher than the book value per share of our outstanding common stock (unless we offer shares pursuant to a rights offering or after obtaining prior approval for such issuance from our stockholders and our independent directors). Accordingly, investors purchasing shares of common stock in offerings pursuant to this prospectus may pay a price per share that exceeds the tangible book value per share after such offering.

Our stockholders will experience dilution in their ownership percentage if they do not participate in our dividend reinvestment plan.

              All dividends declared in cash payable to stockholders that are participants in our dividend reinvestment plan are automatically reinvested in shares of our common stock. As a result, our stockholders that do not participate in our dividend reinvestment plan will experience dilution in their ownership percentage of our common stock over time.

Our stockholders may receive shares of our common stock as dividends, which could result in adverse tax consequences to stockholders.

              In order to satisfy the annual distribution requirement applicable to RICs, we have the ability to declare a large portion of a dividend in shares of our common stock instead of in cash. As long as a portion of such dividend is paid in cash (which portion can be as low as 10% for our taxable years ending on or before December 31, 2011) and certain requirements are met, the entire distribution would be treated as a dividend for U.S. federal income tax purposes. As a result, a stockholder would

48


Table of Contents


be taxed on 100% of the dividend in the same manner as a cash dividend, even though most of the dividend was paid in shares of our common stock.

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

              Sales of substantial amounts of our common stock, or the availability of such common stock for sale, could adversely affect the prevailing market prices for our common stock. If this occurs and continues, it could impair our ability to raise additional capital through the sale of securities should we desire to do so.

The trading market or market value of our publicly issued debt securities may fluctuate.

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

              You should also be aware that there may be a limited number of buyers when you decide to sell your debt securities. This too may materially adversely affect the market value of the debt securities or the trading market for the debt securities.

Terms relating to redemption may materially adversely affect your return on any debt securities that we may issue.

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

Our credit ratings may not reflect all risks of an investment in our debt securities.

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

Ares Capital Corporation and Subsidiaries
Notes to Pro Forma Condensed Consolidated Statements of Operations
Unaudited
(In thousands, except share and per share data unless otherwise stated)

1.     BASIS OF PRO FORMA PRESENTATION

              The unaudited pro forma condensed consolidated statements of operations related to the merger are included for the six months ended June 30, 2010 and for the year ended December 31, 2009. On October 26, 2009, we entered into a definitive agreement to acquire Allied Capital in an all stock transaction (the "Allied Acquisition"). On April 1, 2010, we completed the Allied Acquisition by acquiring the outstanding shares of Allied Capital in exchange for shares of our common stock in a transaction valued at approximately $908 million as of the closing date. Concurrently with the completion of the Allied Acquisition, we assumed and then repaid in full the $137 million of remaining amounts outstanding on Allied Capital's $250 million senior secured term loan. We also assumed all of Allied Capital's other outstanding debt obligations, including approximately $745 million in principal amount of Allied Capital's Unsecured Notes.

              Under the terms of the transaction, each Allied Capital stockholder received 0.325 shares of our common stock for each share of Allied Capital common stock then owned by such stockholder. In connection with the Allied Acquisition, approximately 58.5 million shares of our common stock (including the effect of outstanding in-the money Allied Capital stock options) were issued to Allied Capital's then-existing stockholders, thereby resulting in our then-existing stockholders owning approximately 69% of the combined company and the then-existing Allied Capital stockholders owning approximately 31% of the combined company.

              The Allied Acquisition was accounted for in accordance with the acquisition method of accounting as detailed in ASC 805-10 (previously SFAS No. 141(R)), Business Combinations. The acquisition method of accounting requires an acquirer to recognize the assets acquired, the liabilities assumed and any noncontrolling interest in the acquired entity based on their fair values as of the date of acquisition. As described in more detail in ASC 805-10, if the total acquisition date fair value of the identifiable net assets acquired exceeds the fair value of the consideration transferred, the excess will be recognized as a gain. Upon completion of our determination of the fair value of Allied Capital's identifiable net assets as of April 1, 2010, the fair value of such net assets exceeded the fair value of the consideration transferred, thereby, resulting in the recognition of a gain. The valuation of the investments acquired as part of the Allied Acquisition was done in accordance with Ares Capital's valuation policy (see Notes 2 and 8 to the consolidated financial statements as of and for the period ended June 30, 2010).

Represents cash payment for holders of any "in-the-money" Allied Capital stock options that elected to receive cash

              Ares Capital has elected to be treated as a RIC under subchapter M of the Code and operates in a manner so as to qualify for the tax treatment applicable to RICs. In order to qualify as a RIC, among other things, Ares Capital is required to timely distribute to its stockholders generally at least 90% of its investment company taxable income, as defined by the Code, for each year. The unaudited pro forma condensed consolidated financial information reflects that Ares Capital has made and intends to continue to make the requisite distributions to its stockholders, which will generally relieve Ares Capital from U.S. federal income taxes.

              The unaudited pro forma condensed consolidated statements of operations presented in this document is for illustrative purposes only and does not necessarily indicate the results of operations that would have resulted had the merger and subsequent combination been completed at the beginning of the applicable period presented, nor the impact of expense efficiencies, asset dispositions, share repurchases and other factors. The unaudited pro forma condensed consolidated statements of operations are not indicative of the results of operations in future periods of the combined company.

2.     PRO FORMA ADJUSTMENTS

              The pro forma purchase accounting allocation included in the unaudited pro forma condensed consolidated statements of operations is as follows:

A.
The purchase price of certain investments in debt securities being acquired from Allied Capital was determined by Ares Capital to be less than the expected recovery value of such investments. In accordance with GAAP, subsequent to April 1, 2010, Ares Capital will record the accretion to the expected recovery value in interest income over the remaining term of the investment. Other than what was included in the actual results for Ares Capital for the six months ended June 30, 2010, interest income has not been adjusted to reflect the accretion to the expected recovery value for the periods presented. The accretion for the first 12 months subsequent to April 1, 2010 is estimated to be approximately $12 million. However, there can be no assurance that such accretion will be more or less than such estimate.

B.
The fair value of the outstanding debt assumed from Allied Capital was determined by Ares Capital to be below the face amount of such debt. In accordance with GAAP, subsequent to

Table of Contents

C.
Base management fees were computed based on 1.5% of average total assets other than cash and cash equivalents but including assets purchased with borrowed funds per Ares Capital's investment advisory and management agreement with Ares Capital Management.

D.
Incentive management fees were recomputed based on the formula in Ares Capital's investment advisory and management agreement with Ares Capital Management.

E.
Adjustments to other expenses were made to reflect compensation costs for Allied Capital's employees that would have been covered by the base management fees paid to Ares Capital Management and therefore not incurred by Ares Capital. Additionally, all stock option costs were excluded as such costs would not exist at Ares Capital as there is no stock option plan maintained by Ares Capital. Payments of stock option costs to employees would have been similarly incurred by Ares Capital in the form of incentive management fees paid to Ares Capital Management. Lastly, any actual costs incurred related to the merger and subsequent combination, primarily various transaction costs, were also excluded.

F.
Weighted average shares for the six months ended June 30, 2010 and for the year ended December 31, 2009 have been adjusted to reflect the following:

USE OF PROCEEDS

              Unless otherwise specified in a prospectus supplement, we intend to use the net proceeds from the sale of our securities for general corporate purposes, which includes investing in portfolio companies in accordance with our investment objective and strategies and market conditions. We also expect to use the net proceeds of an offering to repay or repurchase outstanding indebtedness, including indebtedness under (a) the Revolving Credit Facility ($431.0 million outstanding as of September 30, 2010), (b) the CP Funding Facility ($283.4 million outstanding as of September 30, 2010), (c) the CLO Notes under the Debt Securitization ($177.2 million of CLO Notes outstanding as of September 30, 2010) and (d) the Unsecured Notes ($632.6 million of Unsecured Notes outstanding as of September 30, 2010). The interest charged on the indebtedness incurred under the Revolving Credit Facility is based on LIBOR (one, two, three or six month) plus an applicable spread of between 2.50% and 4.00%. As of September 30, 2010, the one, two, three and six month LIBOR were 0.26%, 0.27%, 0.29% and 0.46%, respectively, and the effective LIBOR spread was 3.00%. The Revolving Credit Facility expires on January 22, 2013. Subject to certain exceptions, the interest charged on the CP Funding Facility is based on LIBOR plus an applicable spread of between 2.25% and 3.75% or on a "base rate" (which is the higher of a prime rate, or the federal funds rate plus 0.50%) plus an applicable spread of between 1.25% to 2.75%, in each case based on a pricing grid depending upon the credit rating of the Company. The effective LIBOR spread under the CP Funding Facility on September 30, 2010 is 2.75%. The CP Funding Facility is scheduled to expire on January 22, 2013 (subject to two one-year extension options exercisable upon mutual consent). As of September 30, 2010, the blended pricing of the CLO Notes, excluding fees, was approximately three-month LIBOR plus 0.35%. The CLO Notes mature on December 20, 2019. The interest charged on the Unsecured Notes is as follows: (a) 6.625%, in the case of the 2011 Notes, (b) 6.000%, in the case of the 2012 Notes, and (c) 6.875%, in the case of the 2047 Notes. The 2011 Notes, 2012 Notes and 2047 Notes mature on July 15, 2011, April 1, 2012 and April 15, 2047, respectively. The supplement to this prospectus relating to an offering may more fully identify the use of the proceeds from such offering.

              We anticipate that substantially all of the net proceeds of an offering of securities pursuant to this prospectus and its related prospectus supplement will be used for the above purposes within three months of any such offering, depending on the availability of appropriate investment opportunities consistent with our investment objective and strategies and market conditions, but no longer than within six months of any such offerings.

              Our primary focus is to generate current income and capital appreciation through investments in first and second lien senior loans and mezzanine debt, and, to a lesser extent, equity securities of eligible portfolio companies. In addition to such investments, we may invest up to 30% of our portfolio in opportunistic investments of non-eligible portfolio companies. As part of this 30%, we may invest in debt of middle market companies located outside of the United States. Pending such investments, we will invest a portion of the net proceeds primarily in cash, cash equivalents, U.S. government securities and other high-quality short-term investments. These securities may earn yields substantially lower than the income that we anticipate receiving once we are fully invested in accordance with our investment objective. As a result, we may not be able to achieve our investment objective and/or pay any dividends during this period or, if we are able to do so, such dividends may be substantially lower than the dividends that we expect to pay when our portfolio is fully invested. If we do not realize yields in excess of our expenses, we may incur operating losses and the market price of our shares may decline. See "Regulation—Temporary Investments" for additional information about temporary investments we may make while waiting to make longer-term investments in pursuit of our investment objective.

PRICE RANGE OF COMMON STOCK AND DISTRIBUTIONS

              Our common stock trades on The NASDAQ Global Select Market under the symbol "ARCC." Our common stock has historically traded at prices both above and below its net asset value. It is not possible to predict whether the common stock offered hereby will trade at, above, or below net asset value. See "Risk Factors—Risks Relating to Offerings Pursuant to this Prospectus—Our shares of common stock have traded at a discount from net asset value and may do so again in the future, which could limit our ability to raise additional equity capital."

              The following table sets forth, for each fiscal quarter during the last two fiscal years and the current fiscal year, the net asset value per share of our common stock, the range of high and low closing sales prices of our common stock, the closing sales price as a percentage of net asset value and the dividends or distributions declared by us. On September 30, 2010, the last reported closing sales price of our common stock on The NASDAQ Global Select Market was $15.65 per share, which represented a premium of approximately 10.91% to the net asset value per share reported by us as of June 30, 2010.

              To maintain our RIC status, we must timely distribute generally an amount equal to at least 90% of our investment company taxable income out of the assets legally available for distribution for each year. To avoid certain excise taxes imposed on RICs, we are generally required to distribute during each calendar year an amount at least equal to the sum of (a) 98% of our ordinary income for the calendar year, plus (b) 98% of our capital gains in excess of capital losses for the one-year period ending on October 31 of the calendar year, plus (c) any ordinary income and capital gains for preceding years that were not distributed during such years. If this requirement is not met, we will be required to pay a nondeductible excise tax equal to 4% of the amount by which 98% of the current year's taxable income exceeds the distribution for the year. The taxable income on which an excise tax is paid is generally carried forward and distributed to stockholders in the next tax year. Depending on the level of taxable income earned in a tax year, we may choose to carry forward taxable income in

Table of Contents


excess of current year distributions into the next tax year and pay a 4% excise tax on such income, as required. Our excise tax benefit for the six months ended June 30, 2010 was approximately $0.1 million and $0.1 million for the year ended December 31, 2009. We cannot assure you that we will achieve results that will permit the payment of any cash distributions.

              We maintain an "opt out" dividend reinvestment plan for our common stockholders. As a result, if we declare a cash dividend, then stockholders' cash dividends 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 dividends. See "Dividend Reinvestment Plan."

RATIOS OF EARNINGS TO FIXED CHARGES

              For the six months ended June 30, 2010 and the years ended December 31, 2009, 2008, 2007, 2006 and 2005, the ratios of earnings to fixed charges of the Company, computed as set forth below, were as follows:

              For purposes of computing the ratios of earnings to fixed charges, earnings represent net increase in stockholders' equity resulting from operations plus (or minus) income tax expense including excise tax expense plus fixed charges. Fixed charges include interest and credit facility fees expense and amortization of debt issuance costs.

(1)
Earnings include the net change in unrealized appreciation or depreciation. Net change in unrealized appreciation or depreciation can vary substantially from year to year. Excluding the net change in unrealized appreciation or depreciation, the earnings to fixed charges ratio would be 10.0 for the six months ended June 30, 2010, 5.7 for the year ended December 31, 2009, 4.5 for the year ended December 31, 2008, 3.7 for the year ended December 31, 2007, 5.8 for the year ended December 31, 2006 and 25.6 for the year ended December 31, 2005.

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

              The information contained in this section should be read in conjunction with the "Selected Condensed Consolidated Financial Data of Ares Capital," the "Unaudited Selected Pro Forma Condensed Consolidated Financial Data," the "Unaudited Pro Forma Condensed Consolidated Financial Statements" and our and Allied Capital's financial statements and notes thereto appearing elsewhere in this prospectus or the accompanying prospectus supplement.

OVERVIEW

              We are a specialty finance company that is a closed-end, non-diversified management investment company incorporated in Maryland. We have elected to be regulated as a BDC under the Investment Company Act. We were founded on April 16, 2004 and were initially funded on June 23, 2004 and on October 8, 2004 completed our initial public offering (the "IPO").

              Our investment objective is to generate both current income and capital appreciation through debt and equity investments. We invest primarily in first and second lien senior loans and mezzanine debt, which in some cases includes an equity component like warrants. To a lesser extent, we also make equity investments, which have generally been non-control equity investments of less than $20 million (usually in conjunction with a concurrent loan investment). However, we may increase the size or nature of these investments. Also, as a result of the Allied Acquisition, Allied Capital's equity investments, including equity investments larger than those we have historically made and controlled portfolio company equity investments, became part of our portfolio. We intend to actively seek opportunities over time to dispose of certain of these investments and rotate them into higher-yielding first and second lien senior loans and mezzanine debt investments. However, there can be no assurance that this strategy will be successful. For risks relating to these investments, see "Risk Factors—Risks Relating to Our Investments—Investments in equity securities involve a substantial degree of risk."

              We are externally managed by Ares Capital Management, an affiliate of Ares Management, a global alternative asset manager and an SEC registered investment adviser, pursuant to the investment advisory and management agreement. Ares Operations, an affiliate of Ares Management, provides the administrative services necessary for us to operate.

              As a BDC, we are required to comply with certain regulatory requirements. For instance, we generally have to invest at least 70% of our total assets in "qualifying assets," including securities and indebtedness of private U.S. companies and certain public U.S. companies, cash, cash equivalents, U.S. government securities and high-quality debt investments that mature in one year or less.

              The Company has elected to be treated as a RIC under Subchapter M of the Code and operates in a manner so as to qualify for the tax treatment applicable to RICs. To qualify as a RIC, we must, among other things, meet certain source-of-income and asset diversification requirements and timely distribute to our stockholders generally at least 90% of our investment company taxable income, as defined by the Code, for each year. Pursuant to this election, we generally will not have to pay corporate level taxes on any income that we distribute to our stockholders provided that we satisfy those requirements.

Allied Acquisition

              On April 1, 2010, we consummated the Allied Acquisition in an all stock merger where each existing share of common stock of Allied Capital was exchanged for 0.325 shares of our common stock. The Allied Acquisition was valued at approximately $908 million as of April 1, 2010. In connection therewith, we issued approximately 58.5 million shares of our common stock to Allied Capital's then-existing stockholders, thereby resulting in our then-existing stockholders owning approximately

60


Table of Contents


69% of the combined company and the then-existing Allied Capital stockholders owning approximately 31% of the combined company. See "Risk Factors—Risks Relating to Our Business—We may be unable to realize the benefits anticipated by the Allied Acquisition, including estimated cost savings and synergies, or it may take longer than anticipated to achieve such benefits" for a description of the risks that the Company may face as a result of the Allied Acquisition.

              Accordingly, other than as set forth in the pro forma financial information or otherwise specifically set forth herein, financial information presented herein for and as of periods ending on or prior to March 31, 2010 does not include any information in respect of Allied Capital. In addition, other than as set forth in the pro forma financial information or otherwise specifically set forth herein, financial information for the six months ended June 30, 2010, including, without limitation, with respect to the Company's consolidated statements of operations, stockholders' equity and cash flows, only includes results attributable to Allied Capital for the period beginning April 1, 2010.

CRITICAL ACCOUNTING POLICIES

Basis of Presentation

              The accompanying consolidated financial statements have been prepared on the accrual basis of accounting in conformity with accounting principles generally accepted in the United States, and include the accounts of the Company and its wholly owned subsidiaries. The consolidated financial statements reflect all adjustments and reclassifications which, in the opinion of management, are necessary for the fair presentation of the results of the operations and financial condition as of and for the periods presented. All significant intercompany balances and transactions have been eliminated.

Cash and Cash Equivalents

              Cash and cash equivalents include short-term, liquid investments in a money market fund. Cash and cash equivalents are carried at cost which approximates fair value.

Concentration of Credit Risk

              The Company places its cash and cash equivalents with financial institutions and, at times, cash held in money market accounts may exceed the Federal Deposit Insurance Corporation insured limit.

Investments

              Investment transactions are recorded on the trade date. Realized gains or losses are computed using the specific identification method. Investments for which market quotations are readily available are typically valued at such market quotations. In order to validate market quotations, we look at a number of factors to determine if the quotations are representative of fair value, including the source and nature of the quotations. Debt and equity securities that are not publicly traded or whose market prices are not readily available (i.e., substantially all of our investments) are valued at fair value as determined in good faith by our board of directors, based on the input of our management and audit committee and independent valuation firms that have been engaged at the direction of the board to assist in the valuation of each portfolio investment without a readily available market quotation at least once during a trailing 12-month period and under a valuation policy and a consistently applied valuation process. The valuation process is conducted at the end of each fiscal quarter, with approximately 50% (based on value) of our valuations of portfolio companies without readily available market quotations subject to review by an independent valuation firm each quarter.

              As part of the valuation process, we may take into account the following types of factors, if relevant, in determining the fair value of our investments: the enterprise value of a portfolio company (an estimate of the total fair value of the portfolio company's debt and equity), the nature and

61


Table of Contents


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, a comparison of the portfolio company's securities to publicly traded securities, changes in the interest rate environment and the credit markets generally that may affect the price at which similar investments may be made in the future and other relevant factors. When an external event such as a purchase transaction, public offering or subsequent equity sale occurs, we use the pricing indicated by the external event to corroborate our valuation.

              Because there is not a readily available market value for most of the investments in our portfolio, we value substantially all of our portfolio investments at fair value as determined in good faith by our board of directors, based on the input of our management and audit committee and independent valuation firms under a valuation policy and a consistently applied valuation process. Due to the inherent uncertainty of determining the fair value of investments that do not have a readily available market value, the fair value of our investments may fluctuate from period to period. Additionally, the fair value of our investments may differ significantly from the values that would have been used had a ready market existed for such investments and may differ materially from the values that we may ultimately realize. Further, such investments are generally subject to legal and other restrictions on resale or otherwise are less liquid than publicly traded securities. If we were required to liquidate a portfolio investment in a forced or liquidation sale, we may realize significantly less than the value at which we have recorded it.

              In addition, changes in the market environment and other events that may occur over the life of the investments may cause the gains or losses ultimately realized on these investments to be different than the gains or losses that would be realized based on the valuations currently assigned. See "Risk Factors—Risks Relating to our Investments—Price declines and illiquidity in the corporate debt markets have adversely affected, and may in the future adversely affect, the fair value of our portfolio investments, reducing our net asset value through increased net unrealized depreciation."

              With respect to investments for which market quotations are not readily available, our board of directors undertakes a multi-step valuation process each quarter, as described below:

              Effective January 1, 2008, the Company adopted ASC 820-10 (previously Statement of Financial Accounting Standards No. 157, Fair Value Measurements ("SFAS 157")), which expands the application of fair value accounting for investments (see Note 8 to the consolidated financial statements for the period ended June 30, 2010). Investments acquired as part of the Allied Acquisition were accounted for in accordance with ASC 805-10 (previously SFAS No. 141(R)), Business Combinations, which requires that all assets be recorded at fair value. As a result, the initial amortized cost basis and

62


Table of Contents


fair value for the acquired investments were the same value at April 1, 2010 (see Note 15 to the consolidated financial statements for the period ended June 30, 2010).

Interest Income Recognition

              Interest income, adjusted for amortization of premium and accretion of discount, is recorded on an accrual basis. Discounts and premiums from par value on securities purchased are accreted/amortized into interest income over the life of the respective security using the effective yield method. The amortized cost of investments represents the original cost adjusted for the accretion of discounts and amortization of premiums, if any.

              Loans are generally placed on non-accrual status when principal or interest payments are past due 30 days or more or when there is reasonable doubt that principal or interest will be collected. Accrued interest is generally reversed when a loan is placed on non-accrual status. Interest payments received on non-accrual loans may be recognized as income or applied to principal depending upon management's judgment regarding collectability. Non-accrual loans are restored to accrual status when past due principal and interest is paid and, in management's judgment, are likely to remain current. The Company may make exceptions to this if the loan has sufficient collateral value and is in the process of collection.

Payment-in-Kind Interest

              The Company has loans in its portfolio that contain a payment-in-kind ("PIK") provision. The PIK interest, computed at the contractual rate specified in each loan agreement, is added to the principal balance of the loan and recorded as interest income. To maintain the Company's status as a RIC, this non-cash source of income must be paid out to stockholders in the form of dividends even though the Company has not yet collected the cash.

Capital Structuring Service Fees and Other Income

              The Company's investment adviser seeks to provide assistance to our portfolio companies in connection with the Company's investments and in return the Company may receive fees for capital structuring services. These fees are generally only available to the Company as a result of the Company's underlying investments, are normally paid at the closing of the investments, are generally non-recurring and are recognized as revenue when earned upon closing of the investment. The services that the Company's investment adviser provides vary by investment, but generally consist of reviewing existing credit facilities, arranging bank financing, arranging equity financing, structuring financing from multiple lenders, structuring financing from multiple equity investors, restructuring existing loans, raising equity and debt capital, and providing general financial advice, which concludes upon closing of the investment. Any services of the above nature subsequent to the closing would generally generate a separate fee payable to the Company. In certain instances where the Company is invited to participate as a co-lender in a transaction and does not provide significant services in connection with the investment, a portion of loan fees paid to the Company in such situations will be deferred and amortized over the estimated life of the loan. The Company's investment adviser may also take a seat on the board of directors of a portfolio company, or observe the meetings of the board of directors without taking a formal seat.

              Other income includes fees for asset management, management and consulting services, loan guarantees, commitments, amendments and other services rendered by the Company to portfolio companies. Such fees are recognized as income when earned or the services are rendered.

Foreign Currency Translation

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

              Results of operations based on changes in foreign exchange rates are separately disclosed in the statement of operations. Foreign security and currency translations may involve certain considerations and risks not typically associated with investing in U.S. companies and U.S. government securities. These risks include, but are not limited to, currency fluctuation and revaluations and future adverse political, social and economic developments, which could cause investments in foreign markets to be less liquid and prices more volatile than those of comparable U.S. companies or U.S. government securities.

Accounting for Derivative Instruments

              We do not utilize hedge accounting and marks its derivatives to market through operations.

Offering Expenses

              Our offering costs are charged against the proceeds from equity offerings when received.

Debt Issuance Costs

              Debt issuance costs are being amortized over the life of the related credit facility using the straight line method, which closely approximates the effective yield method.

U.S. Federal Income Taxes

              We have elected to be treated as a RIC under Subchapter M of the Code and operate in a manner so as to qualify for the tax treatment applicable to RICs. In order to qualify as a RIC, among other things, we are required to timely distribute to our stockholders generally at least 90% of investment company taxable income, as defined by the Code, for each year. We have made and intend to continue to make the requisite distributions to our stockholders, which will generally relieve us from U.S. federal income taxes.

              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 dividend distributions into the next tax year and pay a 4% excise tax on such income, as required. To the extent that we determine that our estimated current year annual taxable income will be in excess of estimated current year dividend distributions, we accrue this excise tax, if any, on estimated excess taxable income as taxable income is earned.

              Certain of our wholly owned subsidiaries are subject to U.S. Federal and state income taxes. Income taxes for certain of our subsidiaries are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases as well as operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled.

Dividends to Common Stockholders

              Dividends and distributions to common stockholders are recorded on the record date. The amount to be paid out as a dividend is determined by the board of directors each quarter and is generally based upon the current and expected future earnings estimated by management. Net realized capital gains, if any, are generally distributed at least annually, although we may decide to retain such capital gains for investment.

              We have adopted a dividend reinvestment plan that provides for reinvestment of any distributions we declare in cash on behalf of our stockholders, unless a stockholder elects to receive cash. As a result, if our board of directors authorizes, and we declare, a cash dividend, then our stockholders who have not "opted out" of our dividend reinvestment plan will have their cash dividends automatically reinvested in additional shares of our common stock, rather than receiving the cash dividend. While we generally use primarily newly issued shares to implement the dividend reinvestment plan (especially if our shares are trading at a premium to net asset value), we may purchase shares in the open market in connection with our obligations under the dividend reinvestment plan. In particular, if our shares are trading at a significant enough discount to net asset value and we are otherwise permitted under applicable law to purchase such shares, we intend to purchase shares in the open market in connection with our obligations under our dividend reinvestment plan.

Use of Estimates in the Preparation of Financial Statements

              The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of actual and contingent assets and liabilities at the date of the financial statements and the reported amounts of income or loss and expenses during the reporting period. Actual results could differ from those estimates. Significant estimates include the valuation of investments.

New Accounting Pronouncements

              In June 2009, the Financial Accounting Standards Board ("FASB") issued ASC 860 (previously SFAS No. 166, Accounting for Transfer of Financial Assets, which amends the guidance in SFAS No. 140, Accounting for Transfers and Servicing of Financial Assets and Extinguishments of Liabilities). It eliminates the concept of qualifying special-purpose entities ("QSPEs"), creates more stringent conditions for reporting a transfer of a portion of a financial asset as a sale, clarifies derecognition criteria of the previous guidance, revises how retained interests are initially measured, and removes the guaranteed mortgage securitization recharacterization provisions. ASC 860 requires additional year-end and interim disclosures for public and nonpublic companies that are similar to the disclosures required by FSP FAS 140-4 and FIN 46(R)-8, Disclosures by Public Entities (Enterprises) about Transfers of Financial Assets and Interests in Variable Interest Entities. ASC 860 is effective as of the beginning of a company's first fiscal year that begins after November 15, 2009 (January 1, 2010 for calendar year-end companies), and for subsequent interim and annual reporting periods. ASC 860's disclosure requirements must be applied to transfers that occurred before and after its effective date. Early adoption of ASC 860 is prohibited. We are currently evaluating the effect that the provisions of ASC 860 may have on our financial condition and results of operations.

              In June 2009, FASB issued ASC 810 (previously SFAS No. 167, Amendments to FASB Interpretation No. 46(R), which amends the guidance in FASB Interpretation No. ("FIN") 46(R), Consolidation of Variable Interest Entities). It requires reporting entities to evaluate former QSPEs for consolidation, changes the approach to determining the primary beneficiary of a variable interest entity (a "VIE") from a quantitative assessment to a qualitative assessment designed to identify a controlling financial interest, and increases the frequency of required reassessments to determine whether a company is the primary beneficiary of a VIE. It also clarifies, but does not significantly change, the

65


Table of Contents


characteristics that identify a VIE. ASC 810 requires additional year-end and interim disclosures for public and non-public companies that are similar to the disclosures required by FSP FAS 140-4 and FIN 46(R)-8. ASC 810 is effective as of the beginning of a company's first fiscal year that begins after November 15, 2009 (January 1, 2010 for calendar year-end companies), and for subsequent interim and annual reporting periods. All QSPE's and entities currently subject to FIN 46(R) will need to be reevaluated under the amended consolidation requirements as of the beginning of the first annual reporting period that begins after November 15, 2009. Early adoption of ASC 810 is prohibited. The FASB agreed at its January 27, 2010 meeting to issue an Accounting Standards Update to finalize its proposal to indefinitely defer ASC 810 for reporting enterprises' interests in entities that either have all of the characteristics of investments companies or for which it is industry practice to apply measurement principles for financial reporting purposes consistent with those that apply to investment companies. The provisions of ASC 810 will not have any impact on our financial condition or results of operations.

              In June 2009, FASB issued ASC 2005, (previously SFAS NO. 168, The FASB Accounting Standards Codification and the Hierarchy of Generally Accepted Accounting Principles ("GAAP")—a replacement of FASB Statement No. 162 ("Codification")). This Codification will become the source of authoritative U.S. GAAP recognized by FASB to be applied by nongovernmental entities. Once the Codification is in effect, all of its content will carry the same level of authority, effectively superseding SFAS No. 162, The Hierarchy of Generally Accepted Accounting Principles. In other words, the GAAP hierarchy will be modified to include only two levels of GAAP: authoritative and nonauthoritative. The Codification is not intended to change GAAP, but it will change the way GAAP is organized and presented. The Codification is effective for financial statements issued for interim and annual periods ending after September 15, 2009. In order to ease the transition to the Codification, the Company has provided the Codification cross-reference alongside the references to the standards issued and adopted prior to the adoption of the Codification.

              In January 2010, the FASB issued ASU 2010-06, Fair Value Measurements and Disclosures (Topic 820), Improving Disclosures About Fair Value Measurements. ASU 2010-06 adds new requirements for disclosures about transfers into and out of Level 1 and 2 inputs and separate disclosures about purchases, sales, issuances and settlements relating to Level 3 inputs. It also clarifies existing fair value disclosures about the level of disaggregation and about inputs and valuation techniques used to measure fair value, and entities will be required to provide fair value measurement disclosures for each class of assets and liabilities. ASU 2010-06 is effective for interim and annual reporting periods beginning after December 15, 2009, except for the disclosures about purchases, sales, issuances and settlements in the roll forward of activity in Level 3 fair value measurements. Those disclosures are effective for fiscal years beginning after December 15, 2010. Adoption of ASU 2010-06 is not expected to have a significant impact on the Company's financial condition and results of operations.

When we refer to the "weighted average yield at fair value" in this report, we compute it with respect to particular securities by taking the (a) annual stated interest rate or yield earned plus the net annual amortization of original issue discount and market discount earned on accruing debt included in such securities, and dividing it by (b) total debt and income producing securities at fair value included in such securities. When we refer to the "weighted average yield at amortized cost" in this report, we compute it with respect to particular securities by taking the (a) annual stated interest rate or yield earned plus the net annual amortization of original issue discount and market discount earned on accruing debt included in such securities, and dividing it by (b) total debt and income producing securities at amortized cost included in such securities.

Excludes investments acquired as a part of the Allied Acquisition on April 1, 2010.

              Our investment adviser employs an investment rating system to categorize our investments. In addition to various risk management and monitoring tools, our investment adviser grades the risk of all investments on a scale of 1 to 4 no less frequently than quarterly. This system is intended primarily to reflect the underlying risk of a portfolio investment relative to our initial cost basis in respect of such portfolio investment (i.e. at the time of acquisition), although it may also take into account under certain circumstances the performance of the portfolio company's business, the collateral coverage of the investment and other relevant factors. Under this system, investments with a grade of 4 involve the least amount of risk to our initial cost basis. The trends and risk factors for this investment since origination or acquisition are generally favorable, which may include the performance of the portfolio company or a potential exit. Investments graded 3 involve a level of risk to our initial cost basis that is similar to the risk to our initial cost basis at the time of origination or acquisition. This portfolio company is generally performing as expected and the risk factors to our ability to ultimately recoup the cost of our investment are neutral to favorable. All investments or acquired investments in new portfolio companies are initially assessed a grade of 3. Investments graded 2 indicate that the risk to our ability to recoup the cost of such investment has increased materially since origination or acquisition, including as a result of factors such as declining performance and non- compliance with debt covenants; however, payments are generally not more than 120 days past due. An investment grade of 1 indicates that the risk to our ability to recoup the cost of such investment has substantially increased since origination or acquisition, and the portfolio company likely has materially declining performance. For debt investments with an investment grade of 1, most or all of the debt covenants are out of compliance and payments are substantially delinquent. For investments graded 1, it is not anticipated that we will be repaid in an amount equal to our full initial cost basis. For investments graded 1 or 2, our investment adviser enhances its level of scrutiny over the monitoring of such portfolio company.

              Ares Capital assigned a fair value as of April 1, 2010 to each of the portfolio investments acquired in connection with the Allied Acquisition. Grades on each investment were initially assessed a grade of 3 (i.e., generally the grade we assign a portfolio company at acquisition), reflecting the relative risk to our initial cost basis of such investments. The initial cost basis of each investment acquired in connection with the Allied Acquisition was equal to the fair value of such investment as of April 1, 2010. Many of these portfolio investments were assigned a fair value reflecting a significant discount to Allied Capital's cost basis at the time of Allied Capital's origination or acquisition of the investment. It is important to note that our grading system does not take into account factors or events in respect of the period from when Allied Capital originated or acquired such portfolio investments or the current status of these portfolio investments in terms of compliance with debt facilities, financial performance and similar factors. Rather, it is only intended to measure the risk to Ares Capital's cost basis from the time that Ares Capital acquired the portfolio investment in connection with the Allied Acquisition. Accordingly, it is possible that the grade of certain of these portfolio investments may be reduced or increased in the future.

Income Tax Expense, Including Excise Tax

              The Company has elected to be treated as a RIC under Subchapter M of the Code and operates in a manner so as to qualify for the tax treatment applicable to RICs. In order to qualify as a

71


Table of Contents


RIC, among other things, the Company is required to timely distribute to its stockholders at least 90% of investment company taxable income, as defined by the Code, for each year. Among other things, the Company has, in order to maintain its RIC status, made and intends to continue to make the requisite distributions to its stockholders which will generally relieve the Company from U.S. Federal income taxes.

              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 dividend distributions into the next tax year and pay a 4% excise tax on such income, as required. To the extent that the Company determines that its estimated current year annual taxable income will be in excess of estimated current year dividend distributions, the Company accrues excise tax, if any, on estimated excess taxable income as taxable income is earned. For the three and six months ended June 30, 2010, the Company recorded no amounts for U.S. Federal excise tax. For the three months ended June 30, 2009, the Company recorded no amounts for U.S. Federal excise tax. For the six months ended June 30, 2009, the Company recognized $0.1 million of benefits for U.S. Federal excise tax.

              Certain of our subsidiaries are subject to U.S. Federal and state income taxes. For the three and six months ended June 30, 2010, we recorded a tax expense of $0.7 million and $0.5 million, respectively, for these subsidiaries, and for the three and six months ended June 30, 2009, we recorded a tax expense of approximately $0.1 million and $0.1 million, respectively, for these subsidiaries.

Net Unrealized Gains/Losses

              For the three months ended June 30, 2010, the Company had net unrealized gains of $72.8 million, which were primarily comprised of $125.5 million in unrealized appreciation, $43.3 million in unrealized depreciation and $9.4 million related to the reversal of prior period net unrealized appreciation. Of the total net unrealized gains for the three months ended June 30, 2010, $46.3 million were related to investments acquired as part of the Allied Acquisition, which were primarily comprised of $73.1 million in unrealized appreciation and $26.8 million in unrealized depreciation.
