Michael Forman

Thanks, Robert, and welcome everyone. I would like to thank you all for joining us today.

Earlier this morning we announced that FS KKR Capital Corp. and FS KKR Capital Corp. II have entered into a merger agreement pursuant to which FSKR will merge with and into FSK. Today’s announcement is a significant step toward our long-term strategic goal of creating a premier middle-market lending franchise and industry leading BDC, and we believe a significant step forward for our shareholders.    

Since the establishment of the FS KKR partnership in April of 2018, we have undertaken a disciplined, methodical approach of merging six different BDC entities of varying sizes into what is now poised to become a single company with approximately $15 billion in assets. Over this same time period, both KKR Credit and FS Investments together have attracted some of the most talented investment and operating professionals in the industry to prepare ourselves for the future.

Highlights over the last three years include the December 2018 merger of FSIC and CCT which created FS KKR Capital Corp. A year later, in December of 2019, we completed the merger of four separate, non-traded BDCs to create FS KKR Capital Corp. II which was, at the time, the third largest BDC. In June of this year we successfully listed FS KKR Capital Corp. II on the New York Stock Exchange under the ticker symbol “FSKR.”

The strategic rationale for the proposed merger of FSK and FSKR hinges on our belief that scale is a critical factor in positioning us for access to the higher quality investment flow within the middle market. Just ten years ago the largest BDC had approximately $4.5 billion of assets and the entire BDC Industry was comprised of 15 public companies and approximately $27 billion of assets. Today, the BDC industry has approximately $115 billion of assets spread across nearly 70 traded and non-traded firms, and our franchise manages approximately $15 billion of that $115 billion. Going forward, we believe the advantages of size and scale will be critical competitive elements as non-bank lenders continue to become the financial backbone of the private debt market in the United States. We believe companies that can offer flexible financing solutions, including the ability to access forms of capital ranging from traditional first lien debt to bespoke products such as asset based financing solutions, foreign currency optionality, second lien debt, and minority equity investments will be better positioned to provide their shareholders with a blend of low beta income streams through current dividends coupled with the potential for capital appreciation in certain situations.

In terms of mechanics, the merger of FSK and FSKR will be completed through a stock-for-stock exchange, in which shareholders of FSKR will receive shares of FSK equivalent to the Net Asset Value of the FSKR shares they hold. The combined entity will operate as FS KKR Capital Corp. and trade on the New York Stock Exchange under the ticker symbol “FSK”. In addition, the Board has authorized a $100 million share repurchase program, which is expected to go into effect following the closing of the merger.

Tangible benefits expected as a result of today’s announced merger include:

• Enhanced portfolio diversification consisting of 216 portfolio companies across 23 industries as of September 30, 2020.

• Approximately 72% of the combined portfolio will consist of senior secured debt investments with an average investment size of less than 0.50% of total assets.

• Operational synergies, totaling approximately $5 million, in expected near-term annual cost savings from the elimination of duplicative functions and platform simplification.

• Enhancements to our liquidity profile and the visibility of our publicly traded stock, coupled with the elimination of trading complexities between FSK and FSKR shares.

In addition to these operating benefits, there also are several amendments to our incentive fee structure:

• Beginning at the closing of the merger, the adviser will waive $90 million of incentive fees spread evenly over the first six quarters following the closing. This waiver equates to $15 million per quarter.

• Also upon the closing, the combined company will permanently reduce its incentive fee to 17.5% from the existing level of 20.0%. The hurdle rate will remain at 7.0%. The reduction in the incentive fee from 20.0% to 17.5% will

5

result in approximately $0.07 per share per year of Net Investment Income accretion in perpetuity. In conjunction with the permanent fee reduction, the look back provision will be removed.

And with that, I’ll turn the call over the Dan to provide some additional perspective regarding today’s announcement.

Dan Pietrzak

Thanks, Michael.

In 2018, when we established our partnership with FS Investments, our blueprint for the future highlighted a date such as today, when we could look forward to operating a single company with the competitive attributes we believe this merger provides. As some of you know, the FS KKR BDC franchise is a major component of KKR’s overall credit vertical and represents approximately 20% of KKR’s total credit assets under management. By combining the two vehicles, which are stronger together than apart, we believe we will be better positioned to achieve our long-term goal of being the premier provider of capital to companies operating in the upper middle market.

As Michael mentioned, there are several outward facing benefits associated with today’s announcement. Over the last several years, KKR has invested significant time and resources building out a broad-based team focused on the future. Since the establishment of the FS KKR partnership, we have meaningfully increased the size of

6

our investment team while, at the same time, we have continued to focus on being stewards of the capital entrusted to us. On a pro forma basis, the combined company investment portfolio consists of approximately 71% of either FS KKR or KKR originated assets. As many of you know, we have worked diligently to rotate certain legacy investments out of the portfolio through refinancings, investment sales, and in some instances, restructurings. Since we established the FS KKR partnership, through our third quarter 2020 reported results, we have originated over $8.4 billion of new investments and have experienced cumulative depreciation of $163 million. This equates to a cumulative annualized depreciation rate of 78 basis points during a period which includes the effects of COVID-19. We are proud of our investment performance over this almost three-year period and we look forward to continuing to deliver strong returns in the future.

In terms of key operating statistics, on a pro forma basis, the combined company’s investment portfolio has a weighted average yield on accruing debt investments of 8.6% as of September 30, 2020, and the median leverage and EBITDA of our first lien originated positions are 5.1x and $65 million, respectively, as of September 30, 2020.

From an investment strategy standpoint, our goals will remain the same as we continue to be highly selective in our origination and underwriting process, while continuing to focus on the upper end of the middle market. We believe the combined company will continue to benefit from exposure to Asset Based Finance, which we see as providing compelling risk adjusted returns in the current market, as well as from our Joint Venture,

7

which provides access to some of the more global aspects of the KKR Credit platform, including certain non-eligible portfolio company investments. As a reminder, we are targeting portfolio allocations of 10-to-15% for Asset Based Finance and 10% to our Joint Venture.

With a larger and more diversified balance sheet, the combined company will have the potential to improve our access to the capital markets. We believe a consolidated and simplified capital structure has the potential to provide us with incremental financial flexibility, as the company should benefit from FSK’s investment grade credit ratings and access to the unsecured debt markets. As of September 30, 2020, on a pro forma basis, the combined company’s overall weighted average cost of debt is 3.4%. In terms of leverage and liquidity, the combined company had a net debt-to-equity level of 0.93x at September 30, 2020, which is below our still targeted range of 1-to-1.25x, with immediately available liquidity of approximately $3.3 billion upon closing. This dry powder provides us with a clear runway to pursue portfolio growth in a disciplined manner.

From a forward-looking perspective, we expect that we are poised to continue to deliver on our previously stated goal of providing investors with at least a 9.0% current dividend yield on the combined company’s Net Asset Value upon closing. Simply using our third quarter results for the combined company on a pro forma basis, without providing for any benefit of growth between today and when the transaction is expected to close, results in Net Investment Income per share of approximately $0.58 for the most recent quarter. This equates to an annualized net investment income yield on our current Net Asset Value of approximately 9.5%.

And with that I’ll turn the call back to Michael for a few closing remarks before we open the call for questions.

Michael Forman

Thanks Dan.    

After our announcement this morning, someone commented to me that we must be pleased to have completed this “final step” in terms of the merger. My reaction is quite different. This merger, while beneficial and impactful, represents the beginning rather than the end of a process. The closing of this merger will create a new, dynamic company in the non-bank lending arena. And while we will continue to operate under the BDC regulatory framework, we expect that the combined company will continue to evolve, as we dedicate ourselves to providing much needed capital to companies which are growing and transforming their own respective industries and which, in turn, are helping to lead our country’s economy forward.

On behalf of the entire FS / KKR operating team, a group of over 250 dedicated professionals, I would like to thank everyone for joining us on the call today. We are grateful for your interest and your support. And we hope each of you, your families, and your colleagues remain safe over the coming Thanksgiving holiday.

And with that, Operator, we would like to open the call for questions.
