Commission File No. 814-00827

On August 10, 2018, FS Investment Corporation (“FSIC”) held a conference call to discuss FSIC’s financial results for the quarter ended June 30, 2018. The conference call contained information regarding FSIC’s proposed acquisition of Corporate Capital Trust, Inc. (“CCT”).

The following are excerpts from the transcript of FSIC’s August 10, 2018 conference call discussing FSIC’s proposed acquisition of CCT.

TODD BUILIONE: Finally, we announced the merger of FSIC and CCT on July 23. We believe that merging these entities will provide business and operational synergies in the near term as well as longer term, that will expand shareholder value, specifically through reductions in administrative costs, further expansion and diversification of the investment portfolio and the optimization of our capital structure with lower borrowing costs. We recently filed a preliminary joint proxy statement with the SEC, hope to begin the proxy solicitation process in September, and expect to close before year-end, subject to shareholder approval and, of course, the satisfaction of other closing conditions.

We’ll continue to provide updates on these initiatives in the coming months. With that, I’ll turn the call over to Dan to discuss our portfolio activity during the quarter.

MIKE KELLY: One final point on leverage. Our position with respect to incremental leverage has not changed from what we stated last quarter. And we are pleased to note that S&P and Fitch affirmed FSIC’s investment-grade credit rating and stable outlook following the announcement of the merger.

***

TODD BUILIONE: Thanks, Mike. We appreciate everyone’s time this morning. We’re excited by the benefits we believe this partnership is creating for our investors, and we remain relentlessly focused on delivering the BDC industry’s premier platform. With that, we’ll now open the call up for questions.

***

FIN O’SHEA: Okay. Thank you. And then just to clear things up. There were, of course, a few regime changes on the fee structure surrounding the advisory merger. With the incentive fee, you’re still at about 19.2% incentive fee on pre — as a percent of pre-incentive fee NII. What’s holding back the lookback of kicking in at this point? Is it starting from a low starting period? Or is there a delay in the lookback kicking in?

***

TODD BUILIONE: Oh, wait, wait, wait, no. Sorry. So, the punchline is—Fin, thanks for that question, too. We expect it could kick in next quarter. We’ve kind of had the benefit of prior gains rolling off in prior quarters. But certainly, there’ll be some benefit of that in prospective quarters.
