Item 5.07. Submission of Matters to a Vote of Security Holders.

FS Investment Corporation IV (the “Company”) held its Annual Meeting of Stockholders (the “Annual Meeting”) on June 12, 2017. As of April 20, 2017, the record date for the determination of stockholders entitled to notice of, and to vote at, the Annual Meeting, 20,394,115 shares of common stock were eligible to be voted. At the Annual Meeting, stockholders present in person or by proxy did not represent more than one-third of the outstanding shares of common stock and, therefore, a quorum was not present for the conduct of business. The Company adjourned the Annual Meeting to permit additional time to solicit stockholder votes.

The reconvened meeting (the “Reconvened Meeting”) will be held on July 17, 2017 at 2:00 p.m., Eastern Time, at 201 Rouse Boulevard, Philadelphia, Pennsylvania 19112. Stockholders have been asked to consider and act upon the following proposals, each of which are described in the Company’s definitive proxy statement filed with the Securities and Exchange Commission (the “SEC”) on April 28, 2017 (the “Proxy Statement”):

Valid proxies submitted prior to the Annual Meeting will continue to be valid for the Reconvened Meeting, unless properly changed or revoked prior to votes being taken at the Reconvened Meeting. The record date of April 20, 2017 will remain the same for the Reconvened Meeting.
