Amended and Restated Investment Advisory Agreement

At a special meeting of stockholders of FS KKR Capital Corp., a Maryland corporation (“FSK”), held on May 21, 2021, FSK received stockholder approval to amend and restate the investment advisory agreement, dated December 20, 2018 (the “Original Advisory Agreement”), by and between FSK and FS/KKR Advisor, LLC (the “Advisor”).

On June 16, 2021, FSK entered into an amended and restated investment advisory agreement (the “Amended Advisory Agreement”) with the Advisor. A description of the Amended Advisory Agreement is set forth in “FS KKR Capital Corp. Proposal 3: Approval of FSK Advisory Agreement Amendment Proposal” (“Proposal 3”) in FSK’s joint proxy statement/prospectus, as amended, filed with the Securities and Exchange Commission (the “SEC”) on February 25, 2021 (the “Proxy Statement”) and is incorporated into this Current Report on Form 8-K by reference. As described in Proposal 3, the Original Advisory Agreement was amended to (i) reduce the income incentive fee from 20% to 17.5% and (ii) remove the total return lookback provision applicable to the subordinated incentive fee on income from the Original Advisory Agreement.

In connection with the entry into the Amended Advisory Agreement, the Advisor has also agreed to waive income incentive fees in the amount of $15 million per quarter for the first six full fiscal quarters of operations following the closing Merger (as defined below) for a total waiver of $90 million. In addition, the Advisor has agreed to exclude from the calculation of the subordinated incentive fee on income and the incentive fee on capital gains any changes to the fair value recorded for the assets and liabilities of FS KKR Capital Corp. II (“FSKR” and, together with FSK, the “Funds”) resulting solely from the new cost basis of the acquired FSKR investments determined in accordance with Accounting Standards Codification Topic 805-50, Business Combinations--Related Issues as a result of the Merger.

Information regarding the material relationships between FSK and the Advisor is set forth in “Part I—Item 1. Business—About the Advisor” and “Part III—Item 13. Certain Relationships and Related Transactions, and Director Independence” in FSK’s Annual Report on Form 10-K for the fiscal year ended December 31, 2020, as amended, originally filed with the SEC on March 1, 2021, and is incorporated into this Current Report on Form 8-K by reference.

The foregoing description of the Amended Advisory Agreement does not purport to be complete and is qualified in its entirety by reference to the Amended Advisory Agreement, which is attached hereto as Exhibit 10.1 and is incorporated into this Current Report on Form 8-K by reference.

Item 2.01. Completion of Acquisition or Disposition of Assets.

On June 16, 2021, FSK completed its previously announced merger with FSKR, pursuant to that certain Agreement and Plan of Merger (the “Merger Agreement”), dated as of November 23, 2020, by and among FSK, FSKR, Rocky Merger Sub, Inc., a Delaware corporation and wholly-owned subsidiary of FSK (“Merger Sub”), and the Advisor.

Pursuant to the Merger Agreement, Merger Sub was first merged with and into FSKR, with FSKR continuing as the surviving company (the “First Merger”), and, immediately following the First Merger, FSKR was then merged with and into FSK, with FSK as the surviving company (together with the First Merger, the “Merger”).

In the Merger, each share of FSKR common stock issued and outstanding immediately prior to the effective time of the First Merger was converted into 0.9498 shares of FSK common stock. The exchange ratio was determined based on the net asset value per share of FSKR common stock, divided by the net asset value per share of FSK common stock (determined, in each case, no earlier than 48 hours (excluding Sundays and holidays) prior to the closing date of the Merger). As a result of the Merger, FSK issued an aggregate of approximately 161,374,027 shares of FSK common stock to former FSKR stockholders. As part of the closing of the Merger, FSK will not be paying cash in lieu of fractional shares.

The foregoing description of the Merger and the Merger Agreement does not purport to be complete and is qualified in its entirety by reference to the Merger Agreement, a copy of which was filed by FSK as Exhibit 2.1 to its Current Report on Form 8-K filed on November 24, 2020 and is incorporated into this Current Report on Form 8-K by reference.
