ARCC Ares Capital Corporation

Proposal 1 (Election of Directors)

We urge you to support and vote FOR the election of Michael J Arougheti as a director of the Company:

Michael J Arougheti serves as the Co-Chairperson of our Board of Directors and has been a formative and active Board member since 2009, and our Board believes that Michael J Arougheti brings significant experience, skills and perspective to our Board. Michael J Arougheti has been instrumental in the Company’s success from the beginning, serving as its President or CEO from its initial public offering in 2004 through July 2014, and as the Co-Chair of our Board since July 2014. As a longtime Board member, current Co-Chairperson of our Board and former CEO and President, Michael J Arougheti has contributed significantly to the Company and remains a crucial member of the Company’s Board. In particular, Michael J Arougheti played a prominent role in the Company’s acquisitions of Allied Capital Corporation in 2010 and American Capital Ltd. in 2017, both of which were transformative transactions for the Company. Our Board’s Nominating and Governance Committee and our full Board have unanimously determined that the nomination and election of Michael J Arougheti is in the best interests of the Company and the opportunity for long-term value creation for our stockholders. Additionally, both our Board’s Nominating and Governance Committee and our full Board believe that depriving the Company of the services of Michael J Arougheti as a Board member is not in the best interests of the Company or its stockholders.

We are aware that ISS has adopted a policy of recommending “Against” votes for certain directors of public companies that serve on more than three public company boards of directors while serving as a CEO of another public company. We believe this policy is designed to ensure that executives have sufficient time to focus on the company for which they serve as CEO. Our Board’s Nominating and Governance Committee and our full Board noted that while Michael J Arougheti serves as the CEO and President of Ares Management and sits on four public company boards of directors (Ares Management, Ares Acquisition Corporation, Ares Capital Corporation, and Ares Commercial Real Estate Corporation), all of such companies relate to Ares Management (either directly or companies that are externally managed or sponsored by affiliates of Ares Management). We do not believe that ISS appreciates that the boards on which Michael J Arougheti sits are all Ares affiliated boards and notably, Michael J Arougheti does not hold a board seat on any public company outside of these Ares affiliated companies. Furthermore, our understanding is that ISS policy allows for an exception when service on one of the boards is integral to the CEO’s duties. We believe that Michael J Arougheti’s service on these boards of directors is an essential element of his position at Ares Management, enhances the collaboration across Ares’ vehicles and assists us in accomplishing our goal of delivering attractive risk adjusted investment returns to stockholders throughout market cycles.

We urge you to support and vote FOR the election of Steven B. McKeever as a director of the Company:

Steven B. McKeever served as an independent director of the Company since 2012 and is the Chairperson of our Board’s Nominating and Governance Committee.

We are aware that ISS has adopted a policy of recommending “Against” votes for certain directors of public companies that have governing documents that provide the board with the exclusive power to amend the company’s bylaws. We believe that ISS is expressing this view through their recommendation to withhold support for Steven B. McKeever’s election.

Our Board of Directors believes that it remains in the best interests of the Company and our stockholders if the power to amend our bylaws is vested exclusively in our Board of Directors as is permitted by Maryland law. Since our initial public offering in 2004, the power to amend our bylaws has been vested exclusively with our Board of Directors. This arrangement has served the interests of the Company and our stockholders well, we believe, because under Maryland law, our directors owe legal duties to the Company and our stockholders that require them to act with a reasonable belief that their actions are in the best interests of the Company and our stockholders. On the other hand, under Maryland law, stockholders are not bound by any such legal duty and are permitted to take or to recommend actions that are in their own individual interests as stockholders without taking into account the broader interests of other stockholders or the interests of the Company. As a result of these factors, we believe that our Board of Directors is in the best position to consider possible future bylaw amendments and will adopt such amendments only after concluding that such amendments are in the best interests of the Company and our stockholders.

For the foregoing reasons, we believe the against recommendation is unwarranted and we urge you to vote FOR the election of Michael J Arougheti and Steven B. McKeever as directors of the Company
