PROXY STATEMENT
2013 ANNUAL MEETING OF STOCKHOLDERS

        The proxy card that accompanies this statement is being solicited by the board of directors (the "Board") of Ares Capital Corporation, a Maryland corporation (the "Company," "we," "us" or "our"), for use at the 2013 Annual Meeting of Stockholders (the "Annual Meeting") to be held on June 4, 2013 at 8:00 a.m., Los Angeles Time, at The Century Plaza Towers, 2029 Century Park East, Concourse Level, Conference Room B, Los Angeles, California 90067, or at any adjournment or postponement thereof. This proxy statement, the accompanying proxy card and the Company's Annual Report on Form 10-K, which includes audited financial statements for the year ended December 31, 2012, are first being released to the Company's stockholders on or about April 19, 2013.

        We encourage you to vote your shares, either by voting in person at the Annual Meeting or by granting a proxy (i.e., authorizing someone to vote your shares). If you properly authorize your proxy and the Company receives it in time for the Annual Meeting, the persons named as proxies will vote the shares registered directly in your name in the manner that you specify. If no specification is made, the votes entitled to be cast by such shares will be cast FOR the election of the three director nominees, FOR the ratification of KPMG LLP as the Company's independent registered public accounting firm for the year ending December 31, 2013 and FOR the proposal to authorize the Company, with the approval of the Board, to sell or otherwise issue shares of its common stock at a price below its then current net asset value per share subject to certain limitations set forth herein (including, without limitation, that the number of shares issued does not exceed 25% of its then outstanding common stock).

        Any stockholder "of record" (i.e., stockholders holding shares directly in their name) giving a valid proxy for the Annual Meeting may revoke it before it is exercised by giving a later-dated properly executed proxy, by giving notice of revocation to the Company in writing before or at the Annual Meeting or by attending the Annual Meeting and voting in person. However, the mere presence of the stockholder at the Annual Meeting does not revoke the proxy. If your shares are held for your account by a broker, bank or other institution or nominee, you may vote such shares at the Annual Meeting only if you obtain proper written authority from your institution or nominee and present it at the meeting. If your shares are held for your account by a broker, bank or other institution or nominee, to revoke any voting instructions prior to the time the vote is taken at the Annual Meeting, you must contact such broker, bank or other institution or nominee to determine how to revoke your vote in accordance with their policies a sufficient time in advance of the Annual Meeting.

        Unless revoked as stated above, the shares of common stock represented by valid proxies will be voted on all matters to be acted upon at the Annual Meeting. With respect to the election of directors, proxies cannot be voted for a greater number of persons than the number of nominees named.

        The Board is not aware of any matter to be presented for action at the Annual Meeting other than the matters set forth herein. Should any other matter requiring a vote of stockholders arise, it is the intention of the persons named in the proxy to vote in accordance with their discretion on such matters. Stockholders have no dissenters' or appraisal rights in connection with any of the proposals described herein.

---

        The record date for determination of stockholders entitled to vote at the Annual Meeting is the close of business on April 11, 2013. As of April 11, 2013, there were 268,043,157 shares of the Company's common stock outstanding. Each share of common stock has one vote. The presence, in person or by proxy, of the holders of shares of common stock of the Company entitled to cast a majority of the votes entitled to be cast shall constitute a quorum for the purposes of the Annual Meeting. If there are not sufficient votes for a quorum or to approve or ratify any of the foregoing proposals at the time of the Annual Meeting, the chairman of the meeting may adjourn the Annual Meeting in order to permit further solicitation of proxies by the Company.

        Abstentions and broker non-votes will be deemed to be present for the purpose of determining a quorum for the Annual Meeting. However, abstentions and broker non-votes are not counted as votes cast. A "broker non-vote" with respect to a matter occurs when a broker, bank or other institution or nominee holding shares on behalf of a beneficial owner has not received voting instructions from the beneficial owner on a particular proposal and does not have, or chooses not to exercise, discretionary authority to vote the shares on such proposals.

        The affirmative vote of holders of at least a majority of the total outstanding shares of the Company's common stock is required under the Company's Bylaws (as amended, the "Bylaws") to approve Proposal 1 (to elect three directors to serve for a term of three years, and until their successors are duly elected and qualify). For purposes of the vote on Proposal 1, abstentions and broker non-votes will have the same effect as votes against this proposal.

        The affirmative vote of holders of at least a majority of all of the votes cast at a meeting at which a quorum is present is required for approval of Proposal 2 (to ratify the selection of KPMG LLP as the Company's independent registered public accounting firm). For purposes of the vote on Proposal 2, abstentions and broker non-votes will not be counted as votes cast and will have no effect on the result of the vote.

        The affirmative vote of holders of at least a "majority," as defined in the Investment Company Act of 1940, as amended (the "Investment Company Act"), of (1) the outstanding shares of the Company's common stock and (2) the outstanding shares of the Company's common stock held by persons that are not affiliated persons of the Company, is required to approve Proposal 3 (to authorize the Company, with the approval of the Board, to sell or otherwise issue shares of its common stock at a price below its then current net asset value per share subject to certain limitations set forth herein (including, without limitation, that the number of shares issued does not exceed 25% of its then outstanding common stock)). Under the Investment Company Act, the vote of holders of a "majority" means the vote of the holders of the lesser of (a) 67% or more of the outstanding shares of the Company's common stock present or represented by proxy at the Annual Meeting if the holders of more than 50% of the shares of the Company's common stock are present or represented by proxy and (b) more than 50% of the outstanding shares of the Company's common stock. Abstentions and broker non-votes will have the effect of a vote against Proposal 3.

        The Company will bear the cost of solicitation of proxies in the form accompanying this statement. Proxies will be solicited by mail or by requesting brokers and other custodians, nominees and fiduciaries to forward proxy soliciting material to the beneficial owners of shares of common stock held of record by such brokers, custodians, nominees and fiduciaries, each of whom the Company will reimburse for its expenses in so doing. In addition to the use of mail, directors, officers and regular employees of Ares Capital Management LLC, the Company's investment adviser ("Ares Capital Management" or the "investment adviser") or Ares Operations LLC, the Company's administrator ("Ares Operations" or the "administrator"), without special compensation therefor, may solicit proxies personally, by telephone, by electronic mail or by facsimile, telegram or other electronic means from stockholders.

        The Company has engaged the services of D.F. King & Co., Inc. ("D.F. King") for the purpose of assisting in the solicitation of proxies at an anticipated cost of approximately $15,000, plus reimbursement of certain expenses and fees for additional services requested. Please note that D.F. King may solicit stockholder proxies by telephone on behalf of the Company. They will not attempt to influence how you vote your shares, but only ask that you take the time to authorize your proxy. You may also be asked if you would like to authorize your proxy over the telephone and to have your voting instructions transmitted to the Company's proxy tabulation firm.

PROPOSAL 1: ELECTION OF DIRECTORS

        Under the Company's charter (as amended, the "Charter") and the Bylaws (together with the Charter, the "Charter Documents"), the Company's directors are divided into three classes. Directors are elected for a staggered term of three years each, with a term of office of only one of these three classes of directors expiring each year. Each director will hold office for the term to which he or she is elected and until his or her successor is duly elected and qualifies.

        The terms of Frank E. O'Bryan, Antony P. Ressler and Eric B. Siegel, the Class III directors, will expire at the Annual Meeting, and the nominating and governance committee has recommended, and the Board has nominated, Messrs. O'Bryan, Ressler and Siegel to stand for re-election at the Annual Meeting and to hold office until the annual meeting to be held in 2016 and until their successors are duly elected and qualify. Messrs. O'Bryan, Ressler and Siegel have agreed to serve as directors if elected and have consented to be named as nominees. The Charter Documents provide that directors shall be elected by the affirmative vote of holders of at least a majority of the shares of common stock outstanding and entitled to vote in such election. Therefore, the affirmative vote of holders of at least a majority of the shares of common stock outstanding as of the close of business on the record date is required to elect Messrs. O'Bryan, Ressler and Siegel as directors of the Company for the term for which they have been nominated.

        A stockholder can vote for or withhold his or her vote from such nominee. In the absence of instructions to the contrary, it is the intention of the persons named as proxies to vote such proxy FOR the election of the nominees named herein. If any nominee should decline or be unable to serve as a director, it is intended that the proxy will be voted for the election of such person as is nominated as a replacement by the nominating and governance committee and by the Board. The Board has no reason to believe that any nominee will be unable or unwilling to serve.

        The Board recommends that you vote for the election of Frank E. O'Bryan, Antony P. Ressler and Eric B. Siegel as directors of the Company for the term for which they have been nominated.

Ownership information for those persons who beneficially own 5% or more of the outstanding shares of the Company's common stock is based upon Schedule 13D, Schedule 13G or other filings by such persons with the Commission and other information obtained from such persons.

DOLLAR RANGE OF SECURITIES BENEFICIALLY OWNED BY DIRECTORS

        The following table sets forth the dollar range of the Company's equity securities beneficially owned by the director nominees and each of its other directors as of April 18, 2013. The Company is not part of a "family of investment companies," as the term is defined in the Investment Company Act.

SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

        Pursuant to Section 16(a) of the Exchange Act, the Company's directors and executive officers, and any persons holding 10% or more of its common stock, are required to report their beneficial ownership and any changes therein to the Commission and the Company. Specific due dates for those reports have been established and the Company is required to report herein any failure to file such reports by those due dates. Based solely upon a review of Forms 3, 4 and 5 filed by such persons, the Company believes that each of its directors and executive officers and any persons holding 10% or more of its common stock complied with all Section 16(a) filing requirements applicable to them during the fiscal year ended December 31, 2012.

CORPORATE GOVERNANCE

Director Independence

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

        The Board has determined that the following directors are independent: Ms. Bates and Messrs. Bartlett, McKeever, O'Bryan and Siegel. Based upon information requested from each such director concerning his or her background, employment and affiliations, the Board has affirmatively determined that none of the independent directors has a material business or professional relationship with the Company, other than in his or her capacity as a member of the Board or any committee thereof.

Organization of the Board of Directors

        The Board has established an audit committee and a nominating and governance committee. The Company does not have a compensation committee because its executive officers do not receive any direct compensation from the Company. During 2012, the Board held 11 formal meetings, the audit committee held eight formal meetings, and the nominating and governance committee held seven formal meetings. The Company encourages, but does not require, the directors to attend the Company's annual meeting of its stockholders in person. Eight of the nine directors attended last year's annual meeting of stockholders in person. All directors attended at least 75% of the aggregate number of meetings of the Board and of the respective committees on which they served.

Board Leadership Structure

        The Board monitors and performs an oversight role with respect to the business and affairs of the Company, including with respect to investment practices and performance, compliance with regulatory requirements and the services, expenses and performance of service providers to the Company. Among other things, the Board approves the appointment of the investment adviser, administrator and officers, reviews and monitors the services and activities performed by the investment adviser, administrator and officers and approves the engagement, and reviews the performance of, the Company's independent registered public accounting firm.

        Under the Bylaws, the Board may designate a chairman to preside over the meetings of the Board and meetings of the stockholders and to perform such other duties as may be assigned to him by the Board. The Company does not have a fixed policy as to whether the chairman of the Board should be

17

---

an independent director and believes that its flexibility to select its chairman and reorganize its leadership structure from time to time is in the best interests of the Company and its stockholders.

        Presently, Mr. Rosenthal serves as the chairman of the Board. Mr. Rosenthal is an interested director because he is on the Investment Committee of the investment adviser and is a member of, and serves on the Executive Committee of, APMC, which indirectly controls Ares Management, the managing member of the investment adviser. The Company believes that Mr. Rosenthal's history with the Company, familiarity with the Ares investment platform and extensive experience in the management of private equity and debt investments qualifies him to serve as the chairman of the Board. Moreover, the Company believes that it is best served through its existing leadership structure with Mr. Rosenthal as chairman of the Board, as Mr. Rosenthal's relationship with the investment adviser provides an effective bridge between the Board and the investment adviser, thus ensuring an open dialogue between the Board and the investment adviser and that both groups act with a common purpose.

        The independent directors have designated a lead independent director whose duties include, among other things, chairing executive sessions of the independent directors, acting as a liaison between the independent directors and the chairman of the Board and between the independent directors and management of the Company and the investment adviser, facilitating communication among the independent directors and the Company's counsel, reviewing and commenting on Board and committee meeting agendas and calling additional meetings of the independent directors as appropriate. In August 2010, the Board designated and appointed Mr. Siegel as the lead independent director and Mr. Siegel has served as lead independent director since that time.

        The Company believes that board leadership structures must be evaluated on a case by case basis and that its existing board leadership structure is appropriate. However, the Company continually re-examines its corporate governance policies on an ongoing basis to ensure that they continue to meet the Company's needs.

Board Role in Risk Oversight

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

        As described below in more detail under "Audit Committee" and "Nominating and Governance Committee," the audit committee and the nominating and governance committee assist the Board in performing its risk oversight function and fulfilling its risk oversight responsibilities. The audit committee's risk oversight responsibilities include overseeing the Company's accounting and financial reporting processes, assisting the Board in fulfilling the Board's oversight responsibilities relating to the Company's systems of internal controls regarding finance and accounting and audits of the Company's financial statements and disclosure controls and procedures, and discussing with management the Company's major financial risk exposures and the steps management has taken to monitor and control such exposures, including the Company's risk assessment and risk management policies. The nominating and governance committee's risk oversight responsibilities include selecting, researching and nominating directors for election by the Company's stockholders, developing and recommending to the Board a set of corporate governance principles and overseeing the evaluation of the Board and the its committees.

        The Board also performs its risk oversight function and fulfills its risk oversight responsibilities by working with the Company's Chief Compliance Officer to monitor risk in accordance with the Company's policies and procedures. The Chief Compliance Officer prepares a written report annually discussing the adequacy and effectiveness of the compliance policies and procedures of the Company

18

---

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

        The Company believes that the Board's role in risk oversight is effective and appropriate given the extensive regulation to which it is already subject as a BDC. Specifically, as a BDC the Company must comply with certain regulatory requirements and restrictions that control the levels of risk in its business and operations. For example, the Company's ability to incur indebtedness is limited such that its asset coverage must equal at least 200% immediately after each time it incurs indebtedness, the Company generally has to invest at least 70% of its total assets in "qualifying assets" and, subject to certain exceptions, the Company is subject to restrictions on its ability to engage in transactions with Ares and its affiliates. In addition, the Company elected to be treated as a regulated investment company ("RIC") under the Internal Revenue Code. As a RIC the Company must, among other things, meet certain source of income and asset diversification requirements.

        The Company believes that the extent of the Board's (and its committees') role in risk oversight complements the Board's leadership structure because it allows the Company's independent directors, through the two fully independent Board committees, a lead independent director, executive sessions with each of the Company's Chief Compliance Officer, the Company's independent registered public accounting firm and independent valuation providers, and otherwise, to exercise oversight of risk without any conflict that might discourage critical review.

        The Company believes that board roles in risk oversight must be evaluated on a case by case basis and that the Board's existing role in risk oversight is appropriate. However, the Board re-examines the manner in which it administers its oversight function on an ongoing basis to ensure that it continues to meet the Company's needs.

Audit Committee

        The members of the audit committee are Ms. Bates and Messrs. O'Bryan and Siegel, each of whom is independent for purposes of the Investment Company Act and The NASDAQ Global Select Market's corporate governance regulations. Ms. Bates currently serves as chairperson of the audit committee. The Board has adopted a charter for the audit committee, which is available on the Company's website at www.arescapitalcorp.com. The contents of our website are not intended to be incorporated by reference into this proxy statement or in any other report or document we file with the Commission, and any references to our website are intended to be inactive textual references only.

        The function of the audit committee is to assist the Board in fulfilling its responsibilities by: (i) overseeing the Company's accounting and financial reporting processes and the audits of the Company's financial statements and (ii) reviewing the financial reports and other types of financial information provided by the Company to the public. The audit committee is also responsible for approving the Company's independent registered public accounting firm and recommending them to the Board (including a majority of the independent directors) for approval and submission to its stockholders for ratification, reviewing with its independent registered public accounting firm the plans and results of the audit engagement, approving professional services provided by its independent

19

---

registered public accounting firm, reviewing the independence of its independent registered public accounting firm and reviewing the adequacy of its internal controls and procedures.

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

        This description of the audit committee's role and responsibilities is summary in nature, is not exhaustive and is qualified in its entirety by reference to the charter of the audit committee, which can be accessed via the Company's website at www.arescapitalcorp.com.

        The Board has determined that Ms. Bates and Mr. O'Bryan are each an "audit committee financial expert" within the meaning of the rules of the Commission.

Nominating and Governance Committee

        The members of the nominating and governance committee are Messrs. McKeever, O'Bryan and Siegel, each of whom is independent for purposes of the Investment Company Act and The NASDAQ Global Select Market's corporate governance regulations. Mr. Siegel currently serves as chairman of the nominating and governance committee. The Board has adopted a charter for the nominating and governance committee, which is available on the Company's website at www.arescapitalcorp.com. The nominating and governance committee is responsible for developing and reviewing changes in policies regarding the nomination of directors, selecting, researching and nominating directors for election by the Company's stockholders, selecting nominees to fill vacancies on the Board or a committee of the Board, developing and recommending to the Board a set of corporate governance principles and overseeing the evaluation of the Board and its committees.

        The nominating and governance committee's policy is to identify potential nominees based on suggestions from the President of the Company, members of the nominating and governance committee, other members of the Board, other executive officers, management of the investment adviser and stockholders of the Company and by other means, and to evaluate such persons as a committee. In addition, from time to time, the Board may determine that it requires a director with a particular expertise or qualification and will actively recruit such a candidate.

        In considering which persons to nominate as directors for election by stockholders, the Board and its nominating and governance committee consider the diversity of skills, experiences and perspectives of candidates. The nominating and governance committee has adopted certain policies regarding director nominations that provide that the Board shall take into account candidates that represent a range of backgrounds and experience. As required by such policies, qualified candidates for membership on the Board will be considered without regard to race, color, creed, religion, national origin, age, gender, sexual orientation or disability. The nominating and governance committee will review and evaluate each candidate's character, judgment, skills (including financial literacy), background, experience and other qualifications (without regard to whether a nominee has been recommended by the Company's stockholders), as well as the overall size and composition of the Board, and recommend to the Board for its approval the slate of directors to be nominated for election at the annual meeting of the Company's stockholders. In general, the Company seeks a Board that includes a diversity of perspectives and a broad range of experiences and includes individuals that possess backgrounds, skills, expertise and attributes that allow them to function collaboratively and effectively together in their oversight of the Company. The Board and its nominating and governance committee periodically review board composition and the policies with respect thereto and as part of

20

---

this review, the nominating and governance committee evaluates the effectiveness of its policies, including the provisions with respect to diversity.

        In considering possible candidates for election as a director, the nominating and governance committee takes into account, in addition to such other factors as it deems relevant, the desirability of selecting directors who:

•

are of high character and integrity;



•

are accomplished in their respective fields, with superior credentials and recognition;



•

have relevant expertise and experience upon which to be able to offer advice and guidance to management;



•

have sufficient time available to devote to the affairs of the Company;



•

are able to work with the other members of the Board and contribute to the success of the Company;



•

can represent the long-term interests of the Company's stockholders as a whole; and



•

are selected such that the Board represents a range of backgrounds and experience.

        The nominating and governance committee also considers all applicable legal and regulatory requirements that govern the composition of the Board.

        The nominating and governance committee may consider recommendations for nomination of directors from the Company's stockholders. Nominations made by stockholders must be delivered to or mailed (setting forth the information required by the Bylaws) and received at the Company's principal executive offices not earlier than 150 days nor fewer than 120 days in advance of the first anniversary of the date on which the Company first mailed its proxy materials for the previous year's annual meeting of stockholders; provided, however, that if the date of the annual meeting has changed by more than 30 days from the prior year, the nomination must be received not earlier than the 150th day prior to the date of such annual meeting nor later than the later of (1) the 120th day prior to the date of such annual meeting or (2) the 10th day following the day on which public announcement of such meeting date is first made.

        In addition to information regarding the nominating stockholder as set forth in the Bylaws, a stockholder's notice shall set forth as to each individual whom the stockholder proposes to nominate for election or reelection as a director:

•

the name, age, business address and residence address of such individual;



•

the class, series and number of any shares of stock of the Company that are beneficially owned by such individual;



•

the date such shares were acquired and the investment intent of such acquisition;



•

whether such stockholder believes any such individual is, or is not, an "interested person" of the Company, as defined in the Investment Company Act or is, or is not, "independent" as set forth in the requirements established by The NASDAQ Global Select Market or any other exchange or automated quotation service on which the Company's securities are listed, and information regarding such individual that is sufficient, in the discretion of the Board or any committee thereof or any authorized officer of the Company, to make either such determination; and



•

all other information relating to such individual that is required to be disclosed in solicitations of proxies for election of directors in an election contest (even if an election contest is not involved), or is otherwise required, in each case pursuant to Regulation 14A under the Exchange

21

---

Act (including such individual's written consent to being named in the proxy statement as a nominee and to serving as a director if elected).

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

        This description of the nominating and governance committee's role and responsibilities is summary in nature, is not exhaustive and is qualified in its entirety by reference to the charter of the nominating and governance committee, which can be accessed via the Company's website at www.arescapitalcorp.com.

Compensation Committee

        The Company does not have a compensation committee because its executive officers do not receive any direct compensation from the Company. However, the compensation payable to the investment adviser pursuant to the investment advisory and management agreement is separately approved by a majority of the independent directors in accordance with NASDAQ Marketplace Rule 5605(d).

Communications Between Stockholders and the Board of Directors

        The Board welcomes communications from the Company's stockholders. Stockholders may send communications to the Board, or to any particular director, to the following address: c/o Ares Capital Corporation, 2000 Avenue of the Stars, 12th Floor, Los Angeles, California 90067. Stockholders should indicate clearly the director or directors to whom the communication is being sent so that each communication may be forwarded directly to the appropriate director(s).

Most of the services necessary for the origination and administration of our investment portfolio are provided by investment professionals employed by the investment adviser or the administrator. In addition, we reimburse the administrator for its allocable portion of expenses incurred by it in performing its obligations under the administration agreement, including its allocable portion of the cost of certain of our officers and their respective staffs, and the investment adviser for certain expenses under the investment advisory and management agreement.

        For the year ended December 31, 2012, in accordance with the investment advisory and management agreement, we accrued, and the investment adviser earned, base management fees and incentive fees related to pre-incentive fee net investment income of $86.2 million and $95.2 million, respectively.

PROPOSAL 2: RATIFICATION OF SELECTION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

        The audit committee and the Board, including a majority of the independent directors, have selected KPMG LLP as the independent registered public accounting firm for the Company for the year ending December 31, 2013 and are submitting the selection of KPMG LLP to the stockholders for ratification.

        If the stockholders fail to ratify the selection, the audit committee and the Board will reconsider whether or not to retain KPMG LLP. Even if the selection is ratified, the audit committee and the Board may direct the appointment of a different independent registered public accounting firm at any time during the year if they determine that such a change would be in the best interests of the Company and its stockholders.

        KPMG LLP has advised the Company that neither the firm nor any present member or associate of it has any financial interest, direct or indirect, in the Company or its affiliates.

        The Company expects that a representative of KPMG LLP will be present at the Annual Meeting, will have an opportunity to make a statement if he or she so chooses and will be available to answer questions.

        The Company engaged KPMG LLP to act as its independent registered public accounting firm for 2012.

REPORT OF THE AUDIT COMMITTEE

        The role of the audit committee (the "Audit Committee") of the board of directors (the "Board") of Ares Capital Corporation (the "Company") is to assist the Board in fulfilling its oversight responsibilities by (1) overseeing the Company's accounting and financial reporting processes and the audits of the Company's financial statements and internal control over financial reporting and (2) reviewing the financial reports and other financial information provided by the Company to the public. However, it is not the Audit Committee's duty to plan or conduct the audits or to determine that the Company's financial statements are complete, accurate and in accordance with generally accepted accounting principles or that its internal control over financial reporting is effective. The Company's management is responsible for the preparation, presentation and integrity of its financial statements, for its accounting and financial reporting principles and for the establishment and effectiveness of internal controls and procedures designed to assure compliance with accounting standards and applicable laws and regulations.

        The independent registered public accounting firm is responsible for performing an independent audit of the Company's financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States) and expressing an opinion as to the conformity of such financial statements with generally accepted accounting principles in the United States of America and for auditing and reporting on the effectiveness of the Company's internal control over financial reporting.

        The Audit Committee has reviewed and discussed the Company's audited financial statements, along with management's assessment of the effectiveness of the Company's internal control over financial reporting and the independent registered public accounting firm's evaluation of the Company's internal control over financial reporting, with management and with KPMG LLP, the Company's independent registered public accounting firm for 2012. The Audit Committee has discussed with KPMG LLP the matters required to be discussed by Statement on Auditing Standards No. 61, Communication with Audit Committees, as currently in effect. The Audit Committee has received from KPMG LLP the written disclosures and the letter required by applicable requirements of the Public Company Accounting Oversight Board Rule 3526, Communication with Audit Committees Concerning Independence, regarding the independent registered public accounting firm's communications with the Audit Committee concerning independence, and have discussed with the independent registered public accounting firm its independence.

        The Board has determined that each member of the Audit Committee is independent for purposes of the Investment Company Act of 1940, as amended, and The NASDAQ Global Select Market's corporate governance regulations. The Board has also determined that each member is able to read and understand fundamental financial statements, as such qualifications are defined under the rules of The NASDAQ Global Select Market's corporate governance regulations, and that Ms. Bates and Mr. O'Bryan are each an "audit committee financial expert" within the meaning of the rules of the Securities and Exchange Commission (the "Commission").

        Based on the review and discussions referred to above, the Audit Committee has recommended to the Board that the audited consolidated financial statements for the year ended December 31, 2012 be included in the Company's Annual Report on Form 10-K for such year for filing with the Commission. In addition, the Audit Committee has approved, and recommended to the Board that it approve, KPMG LLP to serve as the Company's independent registered public accounting firm for the year ending December 31, 2013 and that the selection of KPMG LLP be submitted to the Company's stockholders for ratification.

28

---

        The affirmative vote of holders of at least a majority of the votes cast at the Annual Meeting is required for ratification of the selection of KPMG LLP as the Company's independent registered public accounting firm for the fiscal year ending December 31, 2013. The persons named in the accompanying proxy intend to vote proxies received by them in favor of this proposal unless a choice "Against" or "Abstain" is specified.

        The Board, based on the approval and recommendation of the audit committee, recommends voting for ratification of the selection of KPMG LLP as the Company's independent registered public accounting firm for the fiscal year ending December 31, 2013.

PROPOSAL 3: AUTHORIZATION OF THE COMPANY TO SELL OR OTHERWISE ISSUE SHARES OF ITS COMMON STOCK AT A PRICE BELOW ITS THEN CURRENT NET ASSET VALUE PER SHARE SUBJECT TO THE CONDITIONS SET FORTH IN THIS PROPOSAL

        The Company is a closed-end investment company that has elected to be regulated as a BDC under the Investment Company Act. As a BDC, the Company is generally prohibited from issuing its common stock at a price below the then current net asset value per share ("NAV") unless it meets certain conditions, including obtaining stockholder approval.

        As a result, the Company is seeking the approval of its common stockholders so that it may, in one or more public or private offerings of its common stock, sell or otherwise issue shares of its common stock, not exceeding 25% of its then outstanding common stock, at a price below NAV, subject to the conditions set forth in this proposal. If approved, the authorization would be effective for securities issued during a period beginning on the date of such stockholder approval and expiring on the earlier of the anniversary of the date of the Annual Meeting and the date of the Company's 2014 Annual Meeting of Stockholders, which is expected to be held in June 2014. The Company's stockholders approved similar proposals at the Company's 2009, 2010, 2011 and 2012 Annual Meetings of Stockholders.

        The Board, including a majority of the directors who have no financial interest in this proposal and a majority of the independent directors, has approved this proposal as in the best interests of the Company and its stockholders and recommends it to the stockholders for their approval. The Board believes that having the flexibility for the Company to sell its common stock below NAV in certain instances is in the Company's best interests and the best interests of its stockholders. This would, among other things, provide access to capital markets to pursue attractive investment opportunities during periods of volatility, improve capital resources to enable the Company to compete more effectively for high quality investment opportunities and add financial flexibility to comply with BDC and credit facility requirements, including the 1:1 debt to equity ratio. Upon obtaining the requisite stockholder approval, the Company will comply with the conditions described below in connection with any offering undertaken pursuant to this proposal. See below for a discussion of the risks of dilution.

Background and Reasons to Offer Common Stock Below NAV

Market Conditions Have Created, and May in the Future Create, Attractive Investment Opportunities

        As a result of the disruption and volatility in the credit markets over the last several years, the Company has seen a reduction in capital available to certain specialty finance companies and other capital providers, causing a reduction in competition. In particular, the Company believes that favorable investment opportunities to invest at attractive risk-adjusted returns have been created during these periods of disruption and volatility, and may in the future be created if such conditions re-occur. Indeed, during a period of significant credit market volatility when credit spreads increased materially during 2009, the Company, acting pursuant to prior stockholder approval, prudently issued shares of its common stock at a price below NAV and invested the proceeds from such issuance at attractive returns to stockholders. Therefore, these periods of market volatility and dislocation have created, and may

29

---

create again, favorable opportunities for the Company to make investments at attractive risk-adjusted returns, including opportunities that, all else being equal, may increase NAV over the longer-term, even if financed with the issuance of common stock below NAV.

        While recent market conditions have improved, there continue to be periods of volatility and disruption. If these volatile market conditions re-occur or increase in severity and duration, the Company and other companies in the financial services sector may not have access to sufficient debt and equity capital in order to take advantage of favorable investment opportunities that are created during these periods. In addition, the debt capital that will be available, if any, may be at a higher cost and on less favorable terms and conditions in the future. Stockholder approval of the proposal to sell shares of the Company's common stock below NAV, subject to the conditions set forth in this proposal, would provide the Company with the flexibility to invest in such attractive opportunities, which typically need to be made expeditiously.

Greater Investment Opportunities Due to Larger Capital Resources

        The additional capital raised through an offering of the Company's common stock may help the Company generate additional deal flow. With more capital to make investments, the Company could be a more meaningful capital provider and such additional capital would allow it to compete more effectively for high quality investment opportunities. Such investment opportunities may be funded with proceeds of an offering of shares of the Company's common stock.

Status as a BDC and RIC and Maintaining a Favorable Debt to Equity Ratio

        As a BDC and a RIC for tax purposes, the Company is dependent on its ability to raise capital through the issuance of its common stock. RICs generally must distribute substantially all of their earnings to stockholders as dividends in order to achieve pass-through tax treatment, which prevents the Company from using those earnings to support operations, which may include new investments (including investments into existing portfolio companies). Further, BDCs must meet a debt to equity ratio of less than 1:1 in order to incur debt or issue senior securities, which requires the Company to finance its investments with at least as much equity as debt and senior securities in the aggregate. In addition, certain of the Company's debt facilities also require that it maintain a debt to equity ratio of less than 1:1. Therefore, to continue to build the Company's investment portfolio, the Company endeavors to maintain consistent access to capital through the public and private debt markets and the public equity markets enabling it to take advantage of investment opportunities as they arise.

        Exceeding the 1:1 debt to equity ratio could have severe negative consequences for a BDC, including the inability to pay dividends, breaching debt covenants and failure to qualify for tax treatment as a RIC. Although the Company does not currently expect that it will exceed this 1:1 debt to equity ratio, the markets it operates in and the general economy may be volatile and uncertain. Even though the underlying performance of a particular portfolio company may not indicate an impairment or its inability to repay all principal and interest in full, volatility in the capital markets may negatively impact the valuations of investments and result in unrealized write-downs of those investments. Any such write-downs, as well as unrealized write-downs based on the underlying performance of the Company's portfolio companies, if any, will negatively impact stockholders' equity and the resulting debt to equity ratio. Issuing additional equity would improve the Company's debt to equity ratio. In addition to meeting legal requirements applicable to BDCs, having a more favorable debt to equity ratio would also generally strengthen the Company's balance sheet and give it more flexibility to fully execute its business strategy.

Summary

        The Board believes that having the flexibility to issue common stock below NAV in certain instances is in the best interests of the Company and its stockholders. This would, among other things, provide access to capital markets to pursue attractive investment opportunities during periods of volatility, improve capital resources to enable the Company to compete more effectively for high quality investment opportunities and add financial flexibility to comply with BDC and credit facility requirements, including the 1:1 debt to equity ratio. It could also minimize the likelihood that the Company would be required to sell assets that the Company would not otherwise sell, which sales could occur at times that are disadvantageous to the Company.

        While the Company's common stock is currently trading above NAV, it is seeking stockholder approval now in order to provide flexibility if the trading price of its common stock falls below NAV and it desires to issue shares of its common stock below NAV, which typically must be undertaken quickly. The final terms of any such sale will be determined by the Board at the time of issuance and the shares of common stock will not include preemptive rights. Also, because the Company's common stock is currently trading above NAV and it has no immediate plans to issue any shares of its common stock, it is impracticable to describe the transaction or transactions in which such shares of common stock would be issued. Instead, any transaction where the Company issues such shares of common stock, including the nature and amount of consideration that would be received by the Company at the time of issuance and the use of any such consideration, will be reviewed and approved by the Board at the time of issuance. If this proposal is approved, no further authorization from the stockholders will be solicited prior to any such issuance in accordance with the terms of this proposal. If approved, the authorization would be effective for securities issued during a period beginning on the date of such stockholder approval and expiring on the earlier of the anniversary of the date of the Annual Meeting and the date of the Company's 2014 Annual Meeting of Stockholders, which is expected to be held in June 2014.

Trading History

        The following table sets forth, for each fiscal quarter during the last three fiscal years and the first quarter of the current fiscal year, the NAV of the Company's common stock, the range of high and low closing sales prices of its common stock as reported on The NASDAQ Global Select Market and the closing sales price as a premium (discount) to NAV. On April 18, 2013, the last reported closing sales price of the Company's common stock on The NASDAQ Global Select Market was $16.93 per share, which represented a premium of approximately 5.5% to the NAV reported by the Company as of December 31, 2012.

        The Company's common stock has historically traded at prices both above and below its NAV. It is not possible to predict whether its common stock will trade at, above or below NAV in the future.

Examples of Dilutive Effect of the Issuance of Shares Below NAV

        The following three headings and accompanying tables explain and provide hypothetical examples on the impact of a public offering of the Company's common stock at a price less than NAV on three different types of investors:

•

existing stockholders who do not purchase any shares in the offering;



•

existing stockholders who purchase a relatively small amount of shares in the offering or a relatively large amount of shares in the offering; and



•

new investors who become stockholders by purchasing shares in the offering.

        A placement of common stock at a price less than NAV to a third party in a private placement would have an impact substantially similar to the impact on existing stockholders who do not purchase any shares in the public offering described below.

Impact On Existing Stockholders Who Do Not Participate in the Offering

        The Company's existing stockholders who do not participate in an offering below NAV or who do not buy additional shares in the secondary market at the same or lower price as the Company obtains in the offering (after expenses and commissions) face the greatest potential risks. These stockholders will experience an immediate dilution in the net asset value of the shares of common stock they hold and their NAV. These stockholders will also experience a disproportionately greater decrease in their participation in the Company's earnings and assets and their voting power than the increase the Company will experience in its assets, potential earning power and voting interests due to such offering. These stockholders may also experience a decline in the market price of their shares, which often reflects to some degree announced or potential increases and decreases in NAV. This decrease could be more pronounced as the size of the offering and level of discounts increases. Further, if current stockholders do not purchase any shares to maintain their percentage interest, regardless of whether such offering is above or below NAV, their voting power will be diluted.

        The following chart illustrates the level of NAV dilution that would be experienced by a nonparticipating stockholder in three different hypothetical offerings of different sizes and levels of discount from NAV. It is not possible to predict the level of market price decline that may occur.

        The examples assume that the issuer has 30 million shares outstanding, $600 million in total assets and $150 million in total liabilities. The current net asset value and NAV are thus $450 million and $15.00. The chart illustrates the dilutive effect on Stockholder A of (a) an offering of 1.5 million shares of common stock (5% of the outstanding shares) at $14.25 per share after offering expenses and commissions (a 5% discount from NAV), (b) an offering of 3 million shares of common stock (10% of the outstanding shares) at $13.50 per share after offering expenses and commissions (a 10% discount from NAV) and (c) an offering of 6 million shares of common stock (20% of the outstanding shares) at $12.00 per share after offering expenses and commissions (a 20% discount from NAV). The prospectus pursuant to which any discounted offering is made will include a chart based on the actual number of

33

---

shares of common stock in such offering and the actual discount to the most recently determined NAV. It is not possible to predict the level of market price decline that may occur.

Impact On Existing Stockholders Who Do Participate in the Offering

        The Company's existing stockholders who participate in an offering below NAV or who buy additional shares in the secondary market at the same or lower price as the Company obtains in the offering (after expenses and commissions) will experience the same types of NAV dilution as the nonparticipating stockholders, although at a lower level, to the extent they purchase less than the same percentage of the discounted offering as their interest in shares of the Company's common stock immediately prior to the offering. The level of NAV dilution will decrease as the number of shares such stockholders purchase increases. Existing stockholders who buy more than such percentage will experience NAV dilution but will, in contrast to existing stockholders who purchase less than their proportionate share of the offering, experience accretion in NAV over their investment per share and will also experience a disproportionately greater increase in their participation in the Company's earnings and assets and their voting power than the Company's increase in assets, potential earning power and voting interests due to such offering. The level of accretion will increase as the excess number of shares such stockholder purchases increases. Even a stockholder who over-participates will, however, be subject to the risk that the Company may make additional discounted offerings in which such stockholder does not participate, in which case such a stockholder will experience NAV dilution as described above in such subsequent offerings. These stockholders may also experience a decline in the market price of their shares, which often reflects to some degree announced or potential increases and

34

---

decreases in NAV. This decrease could be more pronounced as the size of the offering and level of discounts increases.

        The following chart illustrates the level of dilution and accretion in the hypothetical 20% discount offering from the prior chart (Example 3) for a stockholder that acquires shares equal to (a) 50% of its proportionate share of the offering (i.e., 3,000 shares, which is 0.05% of an offering of 6 million shares) rather than its 0.10% proportionate share and (b) 150% of such percentage (i.e. 9,000 shares, which is 0.15% of an offering of 6 million shares rather than its 0.10% proportionate share). The prospectus pursuant to which any discounted offering is made will include a chart for these examples based on the actual number of shares in such offering and the actual discount from the most recently determined NAV. It is not possible to predict the level of market price decline that may occur.

Impact On New Investors

        Investors who are not currently stockholders and who participate in an offering of shares of the Company's common stock below NAV, but whose investment per share is greater than the resulting NAV due to selling compensation and expenses paid by the Company, will experience an immediate decrease, although small, in the net asset value of their shares and their NAV compared to the price they pay for their shares. Investors who are not currently stockholders and who participate in an offering of shares of the Company's common stock below NAV and whose investment per share is also less than the resulting NAV due to selling compensation and expenses paid by the Company being significantly less than the discount per share, will experience an immediate increase in the net asset value of their shares and their NAV compared to the price they pay for their shares. These investors will experience a disproportionately greater participation in the Company's earnings and assets and their voting power than the Company's increase in assets, potential earning power and voting interests due to such offering. These investors will, however, be subject to the risk that the Company may make additional discounted offerings in which such new stockholder does not participate, in which case such

35

---

new stockholder will experience dilution as described above in such subsequent offerings. These investors may also experience a decline in the market price of their shares, which often reflects to some degree announced or potential increases and decreases in NAV. This decrease could be more pronounced as the size of the offering and level of discounts increases.

        The following chart illustrates the level of dilution or accretion for new investors that would be experienced by a new investor in the same hypothetical 5%, 10% and 20% discounted offerings as described in the first chart above. The illustration is for a new investor who purchases the same percentage (0.10%) of the shares in the offering as Stockholder A in the prior examples held immediately prior to the offering. The prospectus pursuant to which any discounted offering is made will include a chart for these examples based on the actual number of shares in such offering and the actual discount from the most recently determined NAV. It is not possible to predict the level of market price decline that may occur.

Conditions to Sales Below NAV

        If stockholders approve this proposal, the Company will only issue shares of its common stock at a price below NAV pursuant to this stockholder proposal if the following conditions are met:

•

a "required majority" of the Company's directors have determined that any such sale would be in the best interests of the Company and its stockholders; and



•

a "required majority" of the Company's directors, in consultation with the underwriter or underwriters of the offering if it is to be underwritten, have determined in good faith, and as of a time immediately prior to the first solicitation by or on behalf of the Company of firm commitments to purchase such common stock or immediately prior to the issuance of such common stock, that the price at which such shares of common stock are to be sold is not less than a price which closely approximates the market value of those shares of common stock, less any distributing commission or discount.

36

---

        Under the Investment Company Act, a "required majority" of directors means both a majority of the Company's directors who have no financial interest in the transaction and a majority of the Company's independent directors. For these purposes, directors will not be deemed to have a financial interest solely by reason of their ownership of the Company's common stock.

        Prior to the time of issuance, the Board may determine to issue shares of the Company's common stock below NAV in a registered public offering or in a private placement either with or without an obligation to seek to register their resale at the request of the holders. The Board may also determine to use an underwriter or placement agent to assist in selling such shares of common stock if it concludes that doing so would assist in marketing such securities on favorable terms.

Key Stockholder Considerations

        Before voting on this proposal or giving proxies with regard to this matter, stockholders should consider the potentially dilutive effect of the issuance of shares of the Company's common stock at a price that is less than NAV and the expenses associated with such issuance. Any sale of common stock at a price below NAV would result in an immediate dilution to existing common stockholders who do not participate in such sale on at least a pro rata basis. This dilution would include reduction in NAV as a result of the issuance of shares at a price below NAV and a proportionately greater decrease in a stockholder's interest in the earnings and assets of the Company and voting interest in the Company than the increase in the assets of the Company resulting from such issuance.

        The Investment Company Act establishes a connection between common stock sale price and NAV because, when stock is sold or otherwise issued at a sale price below NAV, the resulting increase in the number of outstanding shares is not accompanied by a proportionate increase in the net assets of the issuer. The Board will consider the potential dilutive effect of the issuance of shares at a price below NAV when considering whether to authorize any such issuance pursuant to the stockholder approval being sought here.

        Stockholders should also consider that they will have no subscription, preferential or preemptive rights to additional shares of the common stock proposed to be authorized for issuance pursuant to this proposal, and thus any future issuance of common stock at a price below NAV will dilute such stockholders' holdings of common stock as a percentage of shares outstanding to the extent such stockholders do not purchase sufficient shares in the offering or otherwise to maintain their percentage interest. Further, if current stockholders of the Company do not purchase any shares to maintain their percentage interest, regardless of whether such offering is above or below the then current NAV, their voting power will be diluted.

        As discussed above, it should be noted that the maximum number of shares issuable below NAV that could result in such dilution is limited to 25% of the Company's then outstanding common stock.

        The affirmative vote of holders of at least a "majority," as defined in the Investment Company Act, of (1) the outstanding shares of the Company's common stock and (2) the outstanding shares of the Company's common stock held by persons that are not affiliated persons of the Company, is required to approve this proposal. Under the Investment Company Act, the vote of holders of a "majority" means the vote of the holders of the lesser of (a) 67% or more of the outstanding shares of the Company's common stock present or represented by proxy at the Annual Meeting if the holders of more than 50% of the shares of the Company's common stock are present or represented by proxy or (b) more than 50% of the outstanding shares of the Company's common stock. Abstentions and broker non-votes will have the effect of a vote against this proposal.

        The Board recommends voting for this proposal to authorize the Company to sell or otherwise issue shares of its common stock at a price below its then current NAV subject to the limitations set forth in this proposal.

FINANCIAL STATEMENTS AVAILABLE

        A copy of the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2012 containing audited financial statements accompanies this proxy statement. Such financial statements are hereby incorporated herein by reference.

        Along with this proxy statement, the Company will provide to each stockholder a copy (without exhibits, unless otherwise requested) of its Annual Report on Form 10-K required to be filed with the Commission for the year ended December 31, 2012. Copies of these documents may also be accessed electronically by means of the Commission's home page on the internet at http://www.sec.gov. Other than the financial statements incorporated by reference above, the Annual Report on Form 10-K is not part of the proxy solicitation materials.

HOUSEHOLDING OF PROXY MATERIALS

        The Commission has adopted rules that permit companies and intermediaries (e.g., brokers) to satisfy the delivery requirements for proxy statements and annual reports with respect to two or more stockholders sharing the same address by delivering a single proxy statement and annual report addressed to those stockholders. This process, which is commonly referred to as "householding," potentially means extra convenience for stockholders and cost savings for companies.

        This year a number of brokers with account holders who are the Company's stockholders will be "householding" its proxy materials. A single proxy statement will be delivered to multiple stockholders sharing an address unless contrary instructions have been received from the affected stockholders. If you have received notice from your broker that it will be "householding" communications to your address, "householding" will continue until you are notified otherwise or until you revoke your consent. We will promptly deliver a separate copy of these documents to you upon written or oral request to our Investor Relations Department at Ares Capital Management, 245 Park Avenue, 44^th Floor, New York, New York 10167 or 888-818-5298. If, at any time, you no longer wish to participate in "householding" and would prefer to receive a separate proxy statement and annual report, please notify your broker. Stockholders who currently receive multiple copies of the proxy statement and annual report at their addresses and would like to request "householding" of their communications should contact their brokers.
