Exhibit 99.1

FS/KKR ANNOUNCES SHAREHOLDER APPROVAL OF MERGER OF FS INVESTMENT CORPORATION AND CORPORATE CAPITAL TRUST

FS Investment Corporation to Be Renamed FS KKR Capital Corp. and Trade under Ticker Symbol FSK on NYSE

PHILADELPHIA, PA and NEW YORK, NY – December 3, 2018 – FS/KKR Advisor, LLC (FS/KKR), a partnership between FS Investments and KKR Credit Advisors (US) LLC, today announced that the shareholders of each of FS Investment Corporation (NYSE: FSIC) and Corporate Capital Trust, Inc. (NYSE: CCT) have voted to approve the proposals related to the merger of FSIC and CCT at FSIC’s and CCT’s respective annual meetings of shareholders held on December 3, 2018.

Subject to the satisfaction of certain other closing conditions, FS/KKR currently expects the merger to close on or around December 19, 2018. Upon closing of the merger, FS Investment Corporation will be renamed FS KKR Capital Corp. On the day following the closing of the merger, FS KKR Capital Corp. will begin trading on the New York Stock Exchange under the ticker symbol “FSK.”

In addition, on November 29, 2018, CCT’s board of directors declared a conditional special cash distribution that, subject to the closing of the merger, will be payable on or about December 27, 2018. The amount of the special cash distribution, which will be announced following the closing of the merger, will equal $0.40 per share plus any remaining estimated undistributed net investment income and net realized gains of CCT prior to the closing of the merger after giving effect to the $0.40 per share amount. Notwithstanding the record date, CCT shareholders must remain holders until the closing of the merger to retain rights to the payment of the special cash distribution.

The record date of the special cash distribution will be the close of business on December 18, 2018 but because CCT’s special cash distribution is conditioned on the closing of the merger, shares of CCT’s common stock will trade with a “due bill”. The holder of a share of CCT common stock that receives shares of FSIC in the merger will also receive the special cash distribution for that CCT share. A holder that sells shares of CCT common stock following the record date will not receive the special cash distribution for the CCT shares that are sold.
